Introduction
Why are some teams more effective than others? One potential explanation, of interest to scholars since the earliest days of team research, lies in the way that team members interact in pursuit of their goals. Despite a general acceptance of the importance of team interaction patterns, our understanding of them remains limited. This is because team research to date has predominantly used “statistical approaches directly or indirectly grounded in the general linear model” to capture team interactions (Knight, Kennedy, & McComb, 2016, p. 223). Team interaction patterns, however, are decidedly
An important distinction of a team’s task context is whether it operates in a routine or nonroutine manner (Kerr, 2017). A routine task context is characterized by higher levels of stability and predictability, whereas a nonroutine task context is defined by more complex and novel situations (e.g., Lei, Waller, Hagen, & Kaplan, 2016). To advance the CAS theory at the team level, we identified and examined patterns of team interaction and how they are related to team effectiveness in both task contexts. Our key research question is, “How do team interaction patterns impact team effectiveness, and does this vary in routine or nonroutine task contexts?”
In addition to examining team interaction patterns and how they may vary, given their contexts, the CAS theory advocates combining nonlinear and linear methods to expand our understanding of team effectiveness (Ramos-Villagrasa et al., 2018). Integrative frameworks of team effectiveness and CAS theory promote the inclusion of team processes as antecedents of team effectiveness and “products” of team interaction dynamics (Curşeu, 2006; Marks et al., 2001, p. 358). An influential team process that is known to “result from the dynamic process” of team interaction is information sharing (Curşeu, 2006, p. 252; Mesmer-Magnus & DeChurch, 2009); effective teams are considered to be information-sharing and, subsequently, adaptive entities (Marks et al., 2001). Prior studies on team interaction patterns have examined such patterns and team processes in isolation (e.g., Kanki, Folk, & Irwin, 1991; Kolbe et al., 2014; Stachowski, Kaplan, & Waller, 2009; Zijlstra, Waller, & Phillips, 2012). Some scholars (e.g., Kanki, Folk, & Irwin, 1991) have called for more comprehensive models that integrate team interaction patterns with important team processes as well as task contexts (or contextual dynamics) and effectiveness (see also, Curşeu, 2006; Green & Mitchell, 1979). Through recent advances in CAS theory (including its underlying nonlinear dynamical systems [NDS] approach), we can now examine in more integrative terms which team interaction patterns are associated with team information sharing and team effectiveness in different task contexts.
This article contributes to a better understanding of effective patterns of team interaction. Specifically, we investigate (a) the team-task
Theory and Hypotheses
A CAS Approach to Team Interaction Patterns
Although management scholars have referred to teams as CAS, very few studies have empirically examined the dynamics of team interaction (Ramos-Villagrasa et al., 2012). To advance our understanding of why some teams are more effective than others, more team models need to incorporate these dynamics (McGrath & Tschan, 2007). An NDS approach (Ramos-Villagrasa et al., 2018; Ramos-Villagrasa et al., 2012) requires the modeling and measurement of temporal processes among several elements that interact (Pincus, Kiefer, & Beyer, 2018). Guastello and Liebovitch (2019) argue that “when combined with domain-specific knowledge about psychological phenomena, NDS constructs . . . reveal commonalities in dynamical structure among phenomena that might not have been compared or connected otherwise” (p. 1). To better understand the dynamics of team interaction, task context cannot be bypassed when viewing teams as CAS (Ramos-Villagrasa et al., 2012). In other words, the within-team dynamics can be assumed related to team contexts. As we capture nonlinear team interaction patterns in the present field study, we take an NDS approach and examine how three team patterns are linked to team effectiveness in two different task contexts.
Team interaction patterns are defined as sets of observable behaviors that evolve sequentially and occur at certain time intervals. These patterns are, thus, sequential sets of behavioral events which occur above and beyond chance, if they are all independently distributed (Magnusson, 2000; Magnusson, Burgoon, & Casarrubea, 2016; Waller & Kaplan, 2018). Over time, through successive iterations, team interactions can, thus, become discernible as discrete “patterns” of interaction. Particular interaction patterns may be required for teams to operate effectively (Stachowski et al., 2009). Gorman et al. (2012) argued that
The various patterns of team interaction can be detected with so-called T-pattern analysis (see, for example, Kolbe et al., 2014; Stachowski et al., 2009; Zijlstra et al., 2012), permitting the identification of interactive behavioral chains that are governed by structures of variable stability (Gorman et al., 2012; Magnusson et al., 2016). Herein, we will also use T-pattern analysis to detect team interaction patterns. Addressing how these team interactions are linked to team context and perceived information sharing, as well as to team effectiveness, aims to enhance our understanding of effective team interaction (Gorman, Amazeen, & Cooke, 2010; Gorman et al., 2012). In the text below, we describe how the three team interaction patterns are linked to perceived information sharing, which subsequently influences team effectiveness. We hypothesize also how team-task context may moderate the relation between the three types of interaction patterns and information sharing (see Figure 1).

Research model.
Information Sharing
Team members’ frequent sharing of task-relevant information is considered the bedrock of team effectiveness (Brodbeck, Kerschreiter, Mojzisch, & Schulz-Hardt, 2007; Mesmer-Magnus & DeChurch, 2009). The more information a team can share, analyze, store, and use, the greater the team’s effectiveness, especially for knowledge-intensive teams (Schippers, Homan, & van Knippenberg, 2013; Tost, Gino, & Larrick, 2013). Team members’ proactive sharing of information produces apt team knowledge, which improves coordination as well as decision-making (Klimoski & Mohammed, 1994; Marks, Zaccaro, & Mathieu, 2000; van Ginkel & van Knippenberg, 2009; Zaccaro, Rittman, & Marks, 2001). According to Phelps, Heidl, and Wadhwa (2012), higher degrees of perceived information sharing are associated with effective social interaction in a team. Hence, when interacting with each other, team members can make optimal use of each other’s information and knowledge. Thus, team interaction patterns can be seen as a primary mechanism of how information gets shared and exchanged (Marks et al., 2000; Zellmer-Bruhn, Waller, & Ancona, 2004); they can either enable or inhibit perceived information sharing (Schippers, Edmondson, & West, 2014; Super, Li, Ishqaidef, & Guthrie, 2016).
A specific interaction pattern that is likely to influence both team information sharing and effectiveness is the so-called recurring team interaction pattern. In their taxonomy of information-processing failures, Schippers et al. (2014) highlight habitual team routines as being detrimental to team information sharing. Using habitual “scripts” that teams developed earlier on in their interactions might not spark information sharing any longer in the current moment. As opposed to “mindful” engagement or behavioral adaptation to the moment, recurring patterns of team interaction are likely to curb perceived information sharing. Thus, when a team engages in habitual routines (i.e., in repeatedly co-occurring actions or interactions), it may fail to allow an exchange of information among team members that represents changed situational dynamics. Conversely, teams that adapt quickly are more flexible or open toward each member’s input, such as information and knowledge (Stachowski et al., 2009). Hence, recurring patterns of team interaction might inhibit the open, continuous sharing of opinions, ideas, and knowledge in a team. Recurring team interaction patterns are, thus, likely to create a sense of stability that may lead to rigidity in teams, which, in turn, might limit their effectiveness (LePine, 2003). When teams adhere to many recurring interactions, lower team effectiveness or even tragic team failures may come about as shown in post hoc accident investigations (Gersick & Hackman, 1990; Lei et al., 2016; Stachowski et al., 2009; Zijlstra et al., 2012). Therefore, we can hypothesize that in teams with a high number of recurring team interaction patterns, within-team information sharing fails, leading to lower team effectiveness.
In addition to recurring patterns, heterogeneous team interaction patterns may also affect team effectiveness. When the heterogeneity of team interaction patterns is high, the total number of different interaction patterns in a team is high. 1 Such heterogeneity, thus, entails a relatively large range of different team interaction patterns (Kanki, Folk, & Irwin, 1991). Teams with heterogeneous patterns of interaction are assumed to share more information and knowledge among their members. A high degree of team members’ sharing of information has been associated with high team performance because the information can be used to make sense of the team’s task environment and then take proper action (e.g., Larson, Christensen, Abbott, & Franz, 1996). Although compositional heterogeneity in teams (e.g., in terms of diversity, tenure, or expertise) has been linked to diversity in information and expertise, sparking the interaction and exchange of ideas (Frigotto & Rossi, 2012), heterogeneity in team interaction patterns has not been frequently associated with team performance or information sharing. When teams engage in heterogeneous interaction patterns, team members interact in a more flexible, nonstandard, or prescribed manner with each other (Zijlstra et al., 2012). This greater variety of interaction is assumed, in turn, to lead to a higher level of team information sharing and performance, due to more information and knowledge exchange (Rico, Sánchez-Manzanares, Gil, & Gibson, 2008). Consistent with the idea that compositional heterogeneity is functional for team information sharing (Frigotto & Rossi, 2012), we hypothesize that more diversity in team interaction patterns stimulates team effectiveness through a higher degree of team members’ information sharing.
A third type of pattern, participative team interaction, is also assumed to co-occur with a high degree of perceived information sharing and subsequent team effectiveness. Earlier research on team interaction and communication dynamics has shown that greater amounts of communicative action or participation among leaders and followers nurture the revelation of new information (Cotton, 1993). When team-level interaction patterns are more participative, in the sense that they include more frequent switches among team members, including the team leader, more possibilities to exchange and co-construct relevant information arise (Edmondson & Lei, 2014). Team members in team meetings characterized by highly participative or collaborative patterns are strongly involved in sharing and exchanging their ideas; a steady informational flow among the team members has been associated with collective team behavior (Bourbousson & Fortes-Bourbousson, 2016). This means that participative or collaborative relationships can enable the transfer of information among team members (Phelps et al., 2012). Hence, to perform team tasks effectively, interdependent action and interaction among team members may be required (e.g., Cheng, 1983). Such action or collaborative communication may be associated with a high degree of exchange of information and knowledge (Butchibabu, Sparano-Huiban, Sonenberg, & Shah, 2016). More participative team interaction patterns might, thus, enhance team performance. In addition, meetings have been perceived as more effective when active employee participation is warranted and relevant informational input is provided by the employees as well as their leader (Meinecke, Lehmann-Willenbrock, & Kauffeld, 2017). Based on the above, we hypothesize that participative team interaction patterns are positively related to team effectiveness, and that they are mediated by perceived team information sharing.
Task Context
In team research, the difference between a routine and nonroutine task context has been highlighted as one of the most powerful moderators of team interaction and a contingent condition of information sharing (Chung & Jackson, 2013; Kerr, 2017; Unger-Aviram, Zwikael, & Restubog, 2013). Both task contexts vary in their degree of knowledge-intensiveness (Campbell, 1988). Routine team contexts include team tasks that are more predictable and are handled with standardized work procedures and efficient team interaction (e.g., Resick, Murase, Randall, & DeChurch, 2014). Nonroutine contexts, in contrast, involve team tasks that occur in less predictable situations, with frequent change, requiring relatively unique interactive team behaviors. In an experimental study, Rico et al. (2008) found that team members in a nonroutine or more novel task environment exchanged more information and ideas compared with teams in a routine environment. Although team interaction and effectiveness depend crucially upon the teams’ task context, most prior empirical research focused on one type of task context only (Kerr, 2017). Our inclusion of more than one team-task context enables insight into how team interaction patterns may vary with this context.
Drawing upon the structural contingency approach (Drach-Zahavy & Freund, 2007), which stresses that the optimal course of action is dependent upon the situation, it is likely that the effectiveness of different team interaction patterns is contingent upon the task context (Agliati, Vescovo, & Anolli, 2006; L. A. Perlow, Gittell, & Katz, 2004). Knowledge-intensive teams tend to work on more ambiguous or nonroutine team tasks. Therefore, they need to gather and share information to adapt adequately or adroitly to changing circumstances (Raes, Heijltjes, Glunk, & Roe, 2011). When a team’s task is knowledge-intensive, the team members “experience greater changes and exceptions to their task and hence, are likely to become less familiar with their task” (Wong, 2004, p. 647). Complex issues are also less likely to have standard solutions (Cummings & Cross, 2003; Jehn, 1997). Such issues call for anticipation of dynamic behavioral adjustment by the team (Gardner, Gino, & Staats, 2012; Kozlowski, Gully, Nason, & Smith, 1999). Thus, vigorous, interactive work contexts call for members to behave flexibly, to adapt to continually changing demands and objectives (Gardner et al., 2012).
When a team displays recurring interaction patterns, it relies on a habitual mode of interaction. Kozlowski and colleagues (1999) theorized about the opposite: To be effective, teams undertaking complex or rapidly changing work must integrate their members’ knowledge in an ongoing process of mutual adjustment (Chung & Jackson, 2013; Thompson, 1967; Van de Ven, Delbecq, & Koenig, 1976). Drawing upon CAS theorizing, the wider the variety of interaction patterns that are being displayed by teams, the more this enables them to effectively exchange information and adapt to unpredictable situations (Ramos-Villagrasa et al., 2012). The effect of more recurring interaction patterns on team information sharing may, thus, be negative in knowledge-intensive teams, as this context requires more dynamic anticipation and a less habitual form of interaction. Recurring modes of interaction patterns are likely to occur more in teams with routine tasks (Kerr, 2017; Resick et al., 2014). Because routine tasks are less knowledge-intensive, they can be properly handled with standard or more recurring team interaction patterns and with considerably less information sharing. We hypothesize, therefore, that if recurring team interaction patterns occur in knowledge-intensive teams, they inhibit information sharing and consequently team effectiveness.
Viewing teams as CAS, one could argue that nonroutine team tasks require proactive anticipation or continuous adaptation by team members: In such task contexts, a wide variety of content must be reflected in the team’s interaction patterns (Ramos-Villagrasa et al., 2012). Hence, team interaction patterns that are more varied (i.e., more heterogeneous) might have an impact on how well the team can anticipate a complex task context. Whereas nonroutine situations require continuous monitoring of complex systems and quick adaption to novel situations (e.g., Waller, Gupta, & Giambatista, 2004), routine team tasks require more conventional forms of interaction with lower variety in their content. In line with this, Kanki, Folk, and Irwin (1991) found that in a realistic flight scenario, requiring prescribed sequences of action and communication, highly effective aviation teams exhibited more homogeneous (or protocolized) interaction patterns. Hence, only in routine-type task contexts that require conventional forms of interaction can team members predict each other’s behavior (Kanki, Folk, & Irwin, 1991). In nonroutine or more knowledge-intensive task contexts, constant adaptation and coordination is seen as an important source of team performance (LeBaron, Christianson, Garrett, & Ilan, 2016). When team members in such task contexts show high behavioral conformity, they are unable to address the dynamic demands typical of nonroutine task contexts (Uitdewilligen, Waller, & Zijlstra, 2010). Thus, in nonroutine team-task contexts, homogeneous interaction patterns might reduce information sharing. Nonroutine task contexts call for more “nonscripted” team interactions (LePine, 2003). We surmise, therefore, that in nonroutine task environments, heterogeneous team interaction patterns are beneficial for perceived information sharing.
Teams in nonroutine task environments tend to be confronted with new and changing task elements. To perform well, these teams are required to alter or modify their knowledge or information frequently (Chen, Thomas, & Wallace, 2005). Thus, knowledge-intensive team tasks seem to require continuous exchange, sharing, and interpretation of complex information among team members (Kozlowski & Bell, 2013). In such contexts, in which continuous sharing of member expertise and coordination is important, leaders and followers exchange ideas and develop a shared understanding of their changing task environment (Lei et al., 2016). Kanki, Palmer, and Veinott (1991) found that swift-starting teams, which were constantly facing unpredictable, challenging, and new situations, were more effective when they showed more participative interaction patterns. Curşeu (2006) also took a CAS perspective to better understand the emergence of important team processes and interaction in teams. He suggested that efficient use of information technology creates higher levels of team participation and interaction between virtual team members, which is crucial for high performance. As virtual teams tend to operate mostly in the context of knowledge-intensive tasks (Castellano, Davidson, & Khelladi, 2017) and can, thus, be considered as working in a nonroutine-type task context, highly participative team interaction in such teams enhances the transfer of knowledge and information. Therefore, we expect that in such nonroutine contexts, participative team interaction patterns enhance perceived information sharing.
Method
Sample
A stratified random sample of 150 teams was drawn from one large public-sector organization in the Netherlands; 96 teams, or 64%, accepted our invitation to be videotaped during one randomly selected, regular staff meeting. A total of 1,395 members participated, including the 96 formally appointed team leaders. There was freedom and variety in how the team meetings were conducted, so that possible agenda-setting effects are likely to have been randomly distributed across the teams. In terms of the teams’ tasks, they processed financial-administrative data (in various degrees of knowledge-intensiveness) or created the infrastructure to increase efficiency while complying with regulative, normative, and cultural forces. An example of a nonroutine task context in our sample is a team of software developers; an example of a team operating in a routine task context in our sample is a call center for internal clients. During the videotaped meetings, more than 80% of the team members were present. Immediately following these meetings, they all completed a hard-copy survey to rate the degree of perceived information sharing of their own team. Later, 167 expert ratings of team effectiveness were collected: an average of 1.8 ratings per team. These experts held managerial positions senior to the focal team leaders and were well acquainted with each team.
The team leaders averaged 50.94 years of age (ranging from 27 to 64:
Measures
Team effectiveness
The Gibson, Cooper, and Conger (2009) scale, consisting of four items, was used to capture the overall idea of team effectiveness, rather than whether specific goals were accomplished. A high level of team effectiveness implies that a team accomplishes its assigned tasks very satisfactorily (Gibson et al., 2009). Scores were given by the experts on a Likert-type scale ranging from 1 (
Team information sharing
Using the four items developed by Bunderson and Sutcliffe (2002), team information sharing was rated by the team members on a survey scale from 1 (
Team interaction patterns
We analyzed behavioral patterns in regular team staff meetings (Hoogeboom & Wilderom, 2015; Lehmann-Willenbrock, Meinecke, Rowold, & Kauffeld, 2015; Meinecke & Lehmann-Willenbrock, 2015). Such meetings can provide rich insights into interaction patterns between team members (see also, Agliati et al., 2006; Gardner et al., 2012). They have often served as a prime context for ethnographic-type workplace studies (e.g., Svennevig, 2008; Vine, Holmes, Marra, Pfeifer, & Jackson, 2008). Lehmann-Willenbrock, Chiu, Lei, and Kauffeld (2017) highlighted that interactions during regular staff meetings mirror the social interactions outside the meeting context.
Three separate video cameras were used to record each of the 96 regular staff meetings. To minimize obtrusiveness, all three cameras were set up before each meeting began. The postmeeting surveys found both the videotaped meetings (
Each recording was sent directly to the university and was systematically coded by two members of a rotating panel of 14 trained and supervised MSc and BSc students majoring in Business Administration, Psychology, or Communication Science. They used a 15-page validated codebook and specialized coding software (“The Observer XT”: Noldus, 1991; Noldus, Trienes, Hendriksen, Jansen, & Jansen, 2000; Spiers, 2004). The codebook was developed and refined during earlier behavioral studies (Hoogeboom & Wilderom, 2015). The basis of the codebook was developed in a prior PhD study with a set of mutually exclusive behavioral categories, allowing for exhaustive coding of a full range of leader–follower interactions (Bakeman & Quera, 2011). It was later refined and further detailed on the basis of existing behavioral taxonomies and team communication research. Since then, the codebook has been validly used in other studies (Hoogeboom & Wilderom, 2015).
In total, 18 mutually exclusive micro-behaviors were coded (Table 1: interrater reliability [IRR] = 82.53, kappa = .81, indicating “almost perfect agreement”; Landis & Koch, 1977, p. 165). The unit of analysis when systematically coding the videos was a speech segment that reflected a completed statement (Bales, 1950; Borgatta, 1962). For example, when a team member says, “Yes, exactly,” in reaction to an opinion of another member, this is coded as
Examples of the Video-Coded Behaviors.
Next, pattern recognition algorithms were employed using Theme software (Magnusson, 2000; Magnusson et al., 2016). Theme is capable of discovering behavioral patterns in a temporal order. The program predicts whether the occurrence of sets of sequential behavioral events within a specific time period appear significantly more often than by chance (i.e., when the data are randomized). A so-called T-pattern reflects a sequence of temporal behaviors (see Figure 2). The behavioral input is aggregated by Theme into time sequences of multiple behaviors, based on statistically significant thresholds. First, Theme detects patterns involving two sequential behaviors that occur significantly more often than by chance (e.g.,

Schematic illustration of team interaction patterns.
Theme provides the following information about the detected T-patterns: (a) recurring team interaction patterns (i.e., the total number of times patterns of team interaction occurred), (b) heterogeneous team interaction patterns or the number of unique patterns, 3 and (c) participative team interaction patterns, as represented by the number of actor switches in a pattern (i.e., the number of times that another actor–leader or follower–starts to speak in the patterns). Participative team interaction patterns are, thus, represented by interaction sequences of the same set of actors.
In this study, a total of 110,635 separate behavioral events were coded, and Theme detected 7,879 behavioral patterns. By comparing the average number of detected patterns in the randomized data with the actual number of patterns, we verified that the generated patterns were due neither to chance nor to the presence of many data points (Figure 3). Here, the randomly distributed data produced significantly fewer patterns. This means that the patterns of behavior found during the team meetings had a statistically valid basis for interpretation. All earlier available team pattern studies (Kanki, Folk, & Irwin, 1991; Lei et al., 2016; Stachowski et al., 2009; Zijlstra et al., 2012) had smaller sample sizes and focused on pattern length, complexity, and number of actor switches. The focus of the present study is on the context, effects, and behavioral content of team interaction patterns.

Randomized versus real data.
Across all Theme analyses, the default of pattern occurrences was set at “3”; based on the minimum meeting time of 30 min, a pattern had to occur at least once every 10 min. A similar default was used by Zijlstra et al. (2012). Figure 3, demonstrating that meaningful patterns were detected, also shows that, in terms of the patterns’ length, fewer patterns were detected that consisted of four or five behaviors. Hence, the figure also reveals that complex patterns (consisting of more than three behaviors) are less likely to be repeated within short time intervals. Although the figure combines two distinct “parameters (i.e., pattern occurrence and pattern length),” it implies that if a threshold of 4 would have been used (i.e., a pattern had to occur every 7 min), the more complex patterns would not have been captured by the analysis. Note that the number of patterns was standardized to the shortest video time to control for variability in the staff meeting duration.
T-pattern analysis has been used in several domains, including animal research (Casarrubea, Sorbera, Magnusson, & Crescimanno, 2011), sports science (e.g., Bloomfield, Jonsson, Polman, Houlahan, & O’Donoghue, 2005), child psychology (e.g., Merten & Schwab, 2005), psychiatry, psychopharmacology, ethology, and, only recently, team research (Lei et al., 2016; Stachowski et al., 2009; Zijlstra et al., 2012). The software reveals patterns that would be difficult to observe with the naked eye and are, therefore, easily overlooked.
Task context
The organization distinguishes between teams working in a routine versus nonroutine task context. This classification of teams is a long-standing tradition in public-sector organizations in the Netherlands. The same distinction was adopted here. The teams that work in a routine task context are described as doing comparatively more of the same, repetitive tasks. They do work that includes strong procedural guidelines, including protocols on what to do when deviations occur. Teams that operate in a nonroutine task context are constantly facing new situations and have to continuously adapt their way of working to fit the changing task context. Hence, the level of task complexity varies between the teams that operate in routine versus nonroutine task contexts. In total, 40% of the teams in our sample worked in routine task contexts, and the rest in nonroutine task contexts.
Control variables
Prior studies that examined both information sharing and the nature of team interactions noted that these dynamics are affected by the gender and age of the group members as well as by team tenure and size (e.g., Chang, Bordia, & Duck, 2003; Gardner et al., 2012; Gersick & Hackman, 1990; Stasser, Taylor, & Hanna, 1989). Compared with team members who had spent a long time working together, those team members who had spent less time working together showed more adaptive interaction dynamics (Gorman et al., 2010). Throughout the analyses, individual responses about gender, age, and tenure in the team were aggregated to the team level. Team size was measured by the total number of employees.
Data Analysis
To test the hypotheses, hierarchical multiple regression analyses were conducted. All the reported agreement and reliability indices, for the variables for which more than one rater was present, justify aggregation to the team level (James, Demaree, & Wolf, 1984). The variables and our theorizing were all pitched at the team level. Hence, we did not perform a multilevel analysis (Gooty & Yammarino, 2011). Although we tested the mediation hypothesis with Baron and Kenny’s (1986) four well-known conditions, 4 we strengthened the examination of the moderated-mediation effects by following Edwards and Lambert (2007). Previous tests of moderated mediation, such as splitting the data into subgroups (e.g., Fabrigar & Wegener, 2011), the moderated causal steps procedure for mediation (Baron & Kenny, 1986), or the piecemeal approach to test mediation and moderation, have limitations: They do not reveal which of the dependent, independent, or mediator paths vary as a function of the moderator; or they lower the statistical power by splitting up the sample. Using the path-analytical approach, in addition to Baron and Kenny’s (1986) procedure, provides several important benefits and overcomes the issues associated with these earlier analytical approaches.

Support was found for Hypothesis 1, which proposed that the relationship between recurring patterns of team interaction and team effectiveness is mediated by information sharing. The hierarchical regression analysis shows that (a) recurring team interaction patterns were negatively related to team effectiveness (β = −.34,
No support was found for Hypothesis 2, which stated that heterogeneous team interaction patterns are positively related to team effectiveness through information sharing. Heterogeneous team interaction patterns did not significantly predict team effectiveness (β = −.05,
Hypothesis 3, stating that the relationship between participative team interaction patterns and team effectiveness would be mediated by information sharing, was supported. Participative team interaction patterns were significantly related to team effectiveness (β = .29,

Moderating effect of task context between participative team interaction and team information sharing.
When analyzing the control variables that were included in our hierarchical regression analyses, team age and tenure yielded no significant effects on information sharing and team effectiveness. In some models on team information sharing, a significant negative relationship between team gender and team information sharing appeared (see, for example, β = −.23,
Post Hoc Analysis
No effects were found for the heterogeneous team interaction patterns; this type of pattern was not associated with information sharing or effectiveness. To better understand how all three patterns are linked to perceived information sharing and team effectiveness, we conducted post hoc content analysis of the behaviors involved in the patterns. Table 6 illustrates the most frequently occurring patterns within the 15 most effective and the 15 least effective teams. These teams were selected on the basis of an extreme scores analysis in which the most effective teams had effectiveness scores above 7.5 and the least effective teams had scores below 6.25 (on a scale of 1 to 10, which is the most customary performance rating scale in the Netherlands). The number of frequently occurring patterns was 258 for the most effective teams and 263 for the least effective teams. The pattern characteristics were visualized by the software program but were counted manually. 5 By doing this, we overcame the limitation noted by Gorman et al. (2012) of looking only at mean results; we also engaged in a detailed behavioral content analysis.
Post Hoc Analysis: Differences in the Behavioral Content Between the Most and Least Effective Teams.
Table 6 shows that even the most effective teams showed recurring behavioral patterns, but much less so than the least effective teams. In terms of the content of the interaction patterns of the most effective teams, task-oriented behavior prevails; in the most effective teams, many patterns consist entirely of task-oriented behaviors, such as transactional or initiating structure behavior (e.g., leader transactional–follower initiating structure–follower transactional; see Table 6, row 1). This task-directedness was observed in 54% (i.e., from rows 1, 3, 4, 7, and 8, we add up (33 + 32 + 31 + 22 + 21)/258) of the most effective teams, compared with just 40% in the least effective teams. It is noteworthy that the task-oriented “transactional” and “initiating structure” behaviors were the most dominant type of behaviors in the identified team interaction patterns (Judge & Piccolo, 2004). Surprisingly, transformational behavior hardly played a part in the patterns presented in Table 6. The least effective teams demonstrated much more counterproductive behavior within their interactions; this behavior occurred in 38% of their patterns, compared with 7% in the highly effective teams (Table 6).
Another differentiator between the most effective and least effective teams was the type of team member who initiated a team interaction pattern. In the least effective teams, followers initiated interaction patterns more often than the leaders (80% of the patterns in the least effective teams vs. 27% in the most effective teams). Conversely, more leader-only patterns were visible in the most effective teams; in such patterns, the leader appraised, inspired, and steered his or her team.
Discussion
This CAS study identified three team interaction patterns in two types of real-life task contexts and examined how the patterns relate to perceived team information sharing and team effectiveness. Multimethod/source data on the 96 videotaped teams, involving the micro-behaviors of 1,395 team members, were used to link the patterns to both perceived team information sharing and effectiveness. By combining linear and nonlinear statistical methods, we established that a high frequency of recurring team interaction patterns reduces the sharing of information among team members, especially in nonroutine task contexts, thereby lowering team effectiveness. In both nonroutine and routine task contexts, participative team interaction patterns are shown to be beneficial for perceived information sharing and team effectiveness. No effects were found for the heterogeneous team interaction patterns; this type of team interaction pattern appears not to be associated with team information sharing or effectiveness. Potentially divergent effects of the possibly related team interactive and compositional heterogeneity may have masked the hypothesized effects. Through content analysis, we illustrated that even the highly effective teams show recurring patterns. As noted by Gersick and Hackman (1990), a certain low degree of recurring team interaction is needed to accomplish team goals. The most effective teams appear to have predominantly task-based interaction patterns that only recur occasionally. The least effective teams manifest many more counterproductive behaviors.
We have shown that team dynamics captured with nonlinear techniques might be coupled to important team processes, such as perceived team information sharing. Having identified how this key process may be reached (through nonrecurring, participative team interaction), by viewing teams as CAS and incorporating nonlinear techniques, we extend the linear team research tradition (Ramos-Villagrasa et al., 2018). In addition to establishing that both nonrecurring and participative team interaction patterns are associated with information sharing and effectiveness, our study shows that the effects of those patterns can depend on the team task context. Thus, we empirically support the idea that the task context is a key aspect of teams as CAS (Kerr, 2017; Ramos-Villagrasa et al., 2018; Stevens & Galloway, 2014); highly knowledge-intensive teams are more vulnerable to the negative effects of recurring team interaction patterns, as this limits their information sharing. A greater variety of informational sources, such as those from various external and internal stakeholders, must then be integrated to make high-quality team decisions (Cummings & Cross, 2003). To perform well as a team, members of knowledge-intensive teams must bring together disparate bodies of information and knowledge for robust team sharing of information (Hau, Kim, Lee, & Kim, 2013). Based on our results, this can be accomplished with a high degree of participative deliberation within these teams. More generally, to improve their information sharing capacity and effectiveness, both types of teams should become more participative in their patterns of team interaction. But because little information exchange and elaboration are usually needed in effective routine team-task execution (Resick et al., 2014), many recurring interaction patterns are less detrimental for routine types of team work (see the moderation effect in Figure 4).
Our findings support a key element of the team information sharing theory (Stasser & Titus, 1985). Team information sharing implies adaptive coordination, which, in turn, can explain why teams with participative interaction patterns contribute to a higher level of team effectiveness, and why teams with mainly recurring team interaction patterns contribute so little. Our results show that team information sharing is especially inhibited when teams engage in recurring interaction patterns. In other words, recurring interaction patterns can be seen as signs of team “information processing failure” (Schippers et al., 2014, p. 731). Full utilization of the potentially available informational resources of all team members leads to a high level of team effectiveness. This research outcome points to the potential value of examining leadership
Practical Implications
One of the fundamental characteristics that make a team “a team,” and more than just a collection of individuals, involves the interactions that occur between and among its members. The present study found that team interaction patterns need to match their task environment; an adequate match, in essence, leads to effectiveness. We show evidence in this study that participative team interaction patterns are associated with a team’s extensive sharing of information and, in turn, with team effectiveness in both routine and nonroutine task contexts. Especially in nonroutine task contexts, recurring team interaction patterns are undesirable, because then little information is exchanged among the members of a team, which makes the team ineffective. Thus, to be effective as a team, its members need to become aware of the patterns in their team interactions so that they can move to or stay in a mode in which they can optimally share and use each other’s information.
Especially leaders of teams must become aware of the effectiveness benefits of various interaction patterns; to achieve team effectiveness, high participative and few recurring interaction patterns among the members must be ensured. Team coaches must also be able to detect the two team interaction patterns with the demonstrated opposing effects. Such coaches are increasingly charged with “getting teams out of a rut” or with helping team members and leaders to adapt better to the realities of their task environment (Hackman & Wageman, 2005). On the basis of our results, coaching guidance seems especially important for restoring the effectiveness of knowledge-intensive work teams. A final, more classical strategy to reduce the debilitating recurrent team interaction patterns is changing the composition of a team; how to do that well during an important team assignment is a practically relevant topic deserving future quasi-experimental field research into the degree to which and when certain members of teams are more inclined to engage in recurring team interaction patterns than other members.
Strengths, Limitations, and Future Research
The examination of real-time, behavioral data to understand team effectiveness better has been on the research agenda for at least a decade (Arrow et al., 2004; Cronin et al., 2011; Humphrey & Aime, 2014; Leenders et al., 2015; Mathieu, Maynard, Rapp, & Gilson, 2008; Salas, Cooke, & Rosen, 2008). To the best of our knowledge, no other large-scale, time-based study has coupled various team interaction patterns—derived from real-life organizational team member behaviors—to different team-task contexts. This CAS study has also limitations that must be acknowledged.
First, the study was carried out within a single organization in the Netherlands. Different patterns of team behavior may exist in other national and organizational cultures (Erez & Earley, 1993; M. Perlow, 2003), especially because the Netherlands is known as a low power-distance country. In the Netherlands, participation in a team’s affairs during regularly scheduled team meetings is the norm. Similar research in a high power-distance country must examine whether or not comparable results of participative team interaction patterns on team information sharing and effectiveness can be retrieved. Future studies will, thus, need to examine whether the results are generalizable across nations or cultures.
Second, although our hypothesized relationship between heterogeneous interaction patterns, information sharing, and subsequent team effectiveness yielded no results, other studies did find an effect of heterogeneous interaction patterns on team performance. Kanki, Folk, and Irwin (1991) established that team performance is inhibited in aviation teams when the interaction patterns are more heterogeneous. Aviation teams need to perform in highly standardized and formalized work contexts, with predefined protocols for information sharing. Heterogeneous interaction patterns might inhibit effective information sharing in crisis contexts because, to respond quickly to a rapidly changing situation, the members must share the most crucial information efficiently so as to resolve the situation. Hence, although the suggested relationship could not be confirmed empirically in this study, it was found to be crucial in another context.
Third, the data include one video recording per team of one randomly selected, regularly held team meeting. Nevertheless, all behaviors of the 1,395 team members in those 96 team meetings, including 96 leaders, were reliably coded with a predeveloped behavioral observation scheme. To date, fine-grained analytical techniques have been cumbersome, and team processes have been typically studied as aggregated, perceptual measures, without considering the time-based patterns of team interaction (Leenders et al., 2015). Even though Note 5 shows that the nonlinear software in use still needs improvement, future team-effectiveness research can be greatly enriched with continuous-time data from real-life patterns of team interaction.
Fourth, even though the methods used in this study enable the mapping of three different patterns of real-time team interactions, the field data are cross-sectional. Due to our use of various methods and sources, common-source/method bias is not an issue, and, moreover, the order in which we collected the data for the variables is correctly reflected in our analyses. More research on the antecedents and content of team interaction patterns is recommended so that leaders and coaches are enabled even better to prevent or correct detrimental patterns (Bolger & Laurenceau, 2013). Qualitative examinations of how team interaction patterns unfold over time (e.g., Harrison & Rouse, 2015) could result in a more complete understanding of the development of such patterns.
Fifth, in this study, we rely on a perceptual measure of information sharing. Hence, by using this measure to assess information sharing, we were not able to delineate whether the shared information is either unique or common knowledge (Stasser & Titus, 1985). Moreover, information can take different forms (see, for example, Uitdewilligen & Waller, 2018, who distinguished between fact, interpretation, and projection sharing). Future empirical research on the team dynamics of information sharing must focus on the different types of information sharing needed in various task contexts. Most prior studies on the relationship between information sharing and team effectiveness have relied on the perceptions of team members. Also, using more objective measures of information sharing within teams has become desirable.
Conclusion
We took a CAS approach to better understand how real-life interaction patterns within teams are associated with team effectiveness in different task contexts. As hypothesized, when a large number of recurring team interaction patterns are present, this is negatively related to team effectiveness, through limited team information sharing. Instead, the more teams engage in participative patterns of interaction, the more they engage in information sharing, which, in turn, is associated with higher levels of team effectiveness. Knowledge-intensive teams, in particular, are advised to avoid frequently
