I'm in general interested in how groups can effectively perform and work together. Within this broad theme, I've worked on a number of different topics, such as the role of group diversity, and potential moderators, such as leadership, emotions, reflexivity, regulatory focus, and personality. Next to this work on groups, I am interested in coordination between people in terms of power dynamics and leadership.
My main research focus deals with diversity in (work)groups and more specifically with how one can obtain the benefits in group diversity (see van Knippenberg, De Dreu, & Homan, 2004 for a theoretical framework regarding the effects of diversity in groups; and Homan, in press, for a recent overview). In this respect, I and my colleagues have examined the role of diversity beliefs, cross-categorization, super-ordinate identity, and leadership as potential moderators of the "group diversity - group performance and processes" link in order to examine how detrimental categorization processes can be limited and positive information elaboration processes can be enhanced (e.g., Greer et al., 2012; Homan et al., 2007a; 2007b; 2008; 2010; 2011; 2013; van Knippenberg et al., 2011; 2013). My recent research builds on this previous work by examining the effects of different leadership styles in diverse teams (together with, among others, colleagues at Jacobs University in Bremen), arguing for the crucial role of diversity perceptions (Homan et al., 2010; Rosenauer et al.,2016), diversity training (Homan et al., 2015), testing the moderating influence of error culture in diverse teams (Rupert et al., working paper), looking at antecedents and outcomes of the minority glass ceiling (together with Seval Gündemir and Mark van Vugt, Mosaic grant; Gündemir et al., 2014; Gündemir, Dovidio et al., 2017; Gündemir, Homan et al., 2017), effects of a variety of diversity ideologies on both majority and traditionally underrepresented group members (Gündemir, Martin, & Homan, 2019; Gündemir, Phillips, & Homan, working paper), the glass cliff effect for Asian Americans (Gündemir, Carton, & Homan, 2019) examining gender differences in leadership styles (together with Marleen Redeker, Reinout de Vries, Mark van Vugt [all at the VU], Filip de Fruyt [Ghent University], Danny Rouckhout [University of Antwerp] and Patrick Vermeren [Performance Coaching]), and testing the role of leadership prototypicality in terms of age (Buengeler et al., 2016; Homan et al., working paper). The policy implications of this work have been summarized in a paper in Perspective on Psychological Science (Galinsky, Todd, Homan et al., 2015).
The second line of research deals with how emotions matter in interpersonal interactions at work (Van Kleef et al., 2012), for example, how leader emotional displays affect group performance. We have shown that the epistemic motivation of group members (i.e., the degree to which they are willing to think about the informational aspect of the displayed emotion of the leader) determines the effects of angry vs. happy emotional displays of the leader on actual group functioning (Van Kleef et al., 2009). Additionally, we have found that the followers' level of agreeableness also acts as a crucial moderator in this relationship by showing that groups scoring higher on agreeableness experience more workload and perform less well when confronted with an angry leader than groups scoring lower on agreeableness (Van Kleef et al., 2010). Connected to this work is a line of research examining the role of emotions in groups and conformity of individual group members. Some questions that we are examining there are how emotions displayed by group members influence the behavior of other members within the group (e.g., Heerdink et al., 2013; 2015a; 2015b). This line of research was integrated with my research on diversity in teams in a recent paper on how emotional displays of team members influence the perceptions of diverse teams (Homan et al., 2016).
Within this line of research, we examined the contingencies of reflexivity in groups, showing that reflexivity is especially beneficial for groups that have initially performed below par (Schippers et al., 2013) and the contingencies of regulatory focus in groups (Beersma et al., 2013). This research shows that depending on task structure (regulatory focus), teams require a different focus to perform optimally. Another line of research deals with how one's position in the group influences the behavior of this person in an intergroup negotiation. This research shows that a person's prototypicality will affect his or her behavior in negotiating with another party in such a way that more peripheral group members are more likely to adhere to group norms and to pay better attention to information than more prototypical group members (e.g., Steinel et al., 2010; Van Kleef et al., 2012).
Within this topic, I recently started to get interested in how people attain power in the eyes of others by focusing on norm violating behaviors. More specifically, we examine whether observing someone exhibiting norm violating behaviors results in increased perceptions of power and status conferral (together with Gerben van Kleef, Eftychia Stamkou, Florian Wanders, and Annelies van Vianen, UvA, & Catrin Finkenauer, VU; Stamkou et al., 2016; 2018, in press; Van Kleef et al., 2011; 2012; 2015). Additionally, I have been working with Erik de Kwaadsteniet and Eric van Dijk (Leiden University) on the role of social category information in tacit coordination (de Kwaadsteniet et al., 2012) and Brian Spisak and Mark van Vugt on evolutionary perspectives on leadership and followership (VU University; Spisak et al., 2012). Finally, we have been working on the role of personality and LMX in the relationship between transformational leadership and outcomes (Boer et al., 2016; Deinert et al., 2015), and the role of leadership in the development of identification at work (Horstmeier et al.,2017; Horstmeier et al., 2016).
