European .humai o/'Psychology of Education 2009. yol. XXIK n-'2. 155^168 © 2009, l.S.P.A. Effects of gender role and task content on performance in same-gender dyads: Transactive memory as a potential mediator Estelle Michinov Nicolas Michinov University of Rennes 2, France Pascal Huguet University of Provence and CNRS, France This experiment was designed to examine the effects of gender role and task content on performance in ¡earning dyads and to test the potential mediator effect of an intragroup process related to transactive memory. A total of 44 same-gender dyads participated in the study and were asked to collaborate on a .stereotypically masculine or feminine task in a laboratory setting. Collective performance and transactive memory were measured. As predicted, the /•e.sults .showed an interaetion between group gender and task content on group performance, with male dyads showing poorer performance on a masculine ta.s'k than female dyads. However, contrary to expectations, this moderation effect was not mediated by transactive memory, which appeared as a simple mediator of the relationship between group gender and performance. The results are discussed in the framework ofthe social role theory, and implications for future research in small learning groups are proposed. In educational settings, dyads and small groups are often used to facilitate learning among students (e.g.. Doise & Mugny, 1984, 1997; Gillies, 2004; Johnson & Johnson, 1995; Slavin, 1995). The growing popularity of team approaches to leaming (and working) has led edueational (and organizational) researchers to investigate the factors and processes underlying group effectiveness. More than 50 years of psychological research into small groups has identified key processes and emergent states that enable group members to combine their knowledge, effort, and skills to improve group performance and effectiveness The authors express their sintere gratitude to the E.A. 31 14 "Psychologie des âges ttc la vie".

N, MICHINOV. & P, HUGUET (Koziowski & llgen. 2006). There is solid research-based evidence for the importanee of group composition, task content and interpersonal behaviours in group effectiveness. In the present study, our spécifie aims were to examine: (I) ihe combined effects of gender role and task content on performance in same-gender dyads, and (2) the potential mediator effect of an intragroup process related lo the development of transactive memory systems in same-gender dyads. The reasons for this specific focus were indicated below. With regard to group performance. S,ocial Role Theory- (e.g.. Eagly, 1987; Eagly, Wood, & Diekman. 2000; Wood. 1987) has offered clear evidence for the effects of gender role and task content, Aeeording to this theory, men and women will generally behave in ways that are consistent with their expected soeial roles, and so socialized traits are posited to influence behaviour in groups (Strodtbcek & Mann. 1956; Strodtbeck. James, & Hawkins. 1957). The key assertion of Social Role Theory is that the majority of beliefs about gender differences pertain to communal or agentic attributes (Eagly. 19X7). Communal characteristics involve primarily concern for the welfare of other people, for example, being friendly, unselfish, considerate, and emotionally expressive. In contrast, agentic characteristics describe primarily assertive, ambitious, dominant, independent, self-confident, and competitive individuals. Women arc expected to possess high levels of communal attributes and men high levels of agentic qualities. In addition, it has been demonstrated that perception of competence and expectation of success are higher when the gender orientation of the task is congruent rather than incongruent with participants' gender (e.g.. Dovidio. Brown, Heltman, Ellyson, & Keating. 1988; Karakowsky & McBey. 2001). The task content frequently generates cues about the relative expertise of group members (Miller & Karakowsky. 2005). and consequently women arc more likely to emerge as leaders and be more task-oriented with stcrcotypically feminine than masculine tasks (e.g., Deaux & Emswillcr, 1974; Eagly. Karau. & Makhijani. 1995), Some studies have recently demonstrated that this congruency effect is stronger in same-gender than in mixed-gender groups (e.g.. Karakowsky & Siegel. 1999; Miller &. Karakowsky. 2005; Myaskovsky. Unikel, & Dew. 2005). Miller and Karakowsky (2005). for example, suggested that agentic characteristics are especially likely to occur among men in same-gender groups (i.e., made with only mates), and even more likely when the gender orientation of the task is congruent with the gender of the performer (i.e., masculine task). Similarly. Karakowsky and Siegel (1999) found that men were most likely to ask for feedback when perfonning a malc-oricnted task in a same-gender group than in a mixed-gender group and when they viewed themselves as competent members of the group (ego-dcfensiveness and impression management). Hypothesis I - In the light of studies based on Social Role Theory (e.g.. Karakowsky & Siege!. 1999; Miller & Karakowsky. 2005; Myaskovsky ct al,. 2005), we expected that female dyads would be more likely to activate communal artrihuWs of gender stereotypes than male dyads, and would consequently achieve better collective performance, especially in a congruent feminine task. Conversely, we expected that male dyads would be more likely to activate agentic attributes than female dyads and achieve poorer collective performance, especially in a congruent masculine task. To explain this moderation effect of task content on collective performance in samegender dyads, researchers have proposed that women and men collaborating in same-gender dyads may have different interaction styles and cooperative attitudes (c,g. Eagly. Wood, & Diekman, 2000; Wood & Karten. 1986). In the present study, we suggest that this moderation effect eould be explained by male and female differences in communication, coordination and collaboration behaviours within groups. As members collaborate, they encode and recall information together, and they may build knowledge that becomes embedded in a group's structures and processes (King. 1998; Lewis, Lange. & Gillis. 2005; Moreland. 1999). Knowledge embedding has been studied in a system called the Transactive Memory System or TMS' (Wegner, 1986). which has been shown to influence group leaming and performance. A TMS occurs when two or more people cooperatively encode, store, retrieve, and communicate information and knowledge (Hollingshead. 2001; Wegner, 1986), As observed GENDER ROLE AND TRANSACTIVE MEMORY 157 by Wegner (1986): "One person has access to information in another's memory by virtue of knowing that the other person is a location for an item with a certain labe!. This allows both people to depend on communication with each other for the enhancement of iheir personal memory stores" (p. 189, Wegner. 1986). TMS are more likely to develop within groups when grotip members have trained together and have the opporttinity to communicate with each other directly (e.g.. Lewis, 2003; Liang, Moreland. & Argote, 1995; Moreland, 1999; Moreland & Myaskovsky, 2000). Thus, people may rely on others to process and encode knowledge related to their area of expertise within a TMS (Hollingshcad, 2000). The benefits of transactive memory for group performance have been demonstrated in a wide variety of tasks in groups of different sizes (e.g.. Hollingshead. 1998; Wegner, Erbcr. & Raymond, 1991), in the laboratory (Hollingshead, 2001; Liang ct al.. !995). work organizations (e.g., Austin, 2003; Lewis, 2003; Michinov, Olivier-Chiron, Rusch, & Chiron, 2008; Zhang, Hempel, Han. & Tjosvold, 2007) and leaming contexts (e.g., Michinov, 2007; Michinov & Michinov. 2009). Relating social role theory and transative memorv Despite this variety of studies on TMS. most e.\periments in laboratory sctting.s have involved same-gender groups with masculine tasks (e.g., radio assembly task). Surprisingly, the influence of gender role and task content has been widely neglected in the area of TMS, except in a few recent studies (e.g.. HoMingshead & Fraidin, 2003; Myaskovsky ct a l , 2005). For example, Hollingshcad and Fraidin (2003) found that participants who expected to work with other-gender partners learned more information in categories consistent with gender stereotypes. Thus, it seems that gender stereotypes may influence the development and/or the use of transactive memory systems within groups without any effective communieation between group members. In another study in which participants were involved in effective interactions, Myaskovsky ct al. (2005) examined group perlbnnance and intragroup process such as transactive memory system as a function of whether participants worked in mixed- or same-gender groups. They did not tlnd any effect on performance or transactive memory measures, but only differences in interpersonal behaviour. Thus, women collaborating in same-gender groups were highly task-oriented, whereas men tended to be self-focused in a similar situation. The authors suggested that their results may have been specific to the "stercotypically masculine" task (i.e., radio assembly). The present sttidy was designed to further earlier research (e.g.. Wood, 1987) which found that task contents or settings account for perfonnance differences between women and men, by comparing masculine and feminine tasks. Hypothesis 2 - Based on previous studies (e.g.. Hollingshcad & Fraidin, 2003; Myaskovsky et al., 2005). we expected that transactive memory would be a mediator of ihe interaction between task content and gender role in group performance. Thus, female dyads collaborating on a congruent feminine task would become more task-oriented, and this attention shift eould positively affect encoding, storage and retrieval of group members' knowledge (i.e., TMS. Wegner, 1986), and consequently group performance. Conversely, male dyads collaborating on a congruent masculine task would become more self-focused, and this attention shift could negatively affect TMS and group performance. Method Participants and design A total of 88 university students (44 men, 44 women) in a Freneh University partieipated in this study. Students were enrolled in different academic programs: 23 [Female(f)^15, Male(m)=9j were psychology students, 28 (1=13, m-18) were students in arts, humanities and 158 E. MICHINOV, N. MICHINOV, & P. HUGUET social sciences, and 31 (f=16. m^l7) were students in language and literature. There was no difference in age between the male and female participants (Ms=20.0^ and 19.81 years, respectively). The students, who all participated voluntarily, did not know each other, and were randomly assigned to 44 same-gender dyads (22 female, 22 male dyads), which were then assigned either stereotypically masculine or feminine tasks. Materials and procedure The experiment was presented to participants as a study on collaboration within groups. A detailed procedural scenario was given to the experimenter to ensure that the same instructions were delivered to all groups in the same way. The experiment was divided into two sessions, sequentially organized for encoding and reeall of a complex figure, ln the first session, participants were trained to encode a complexified version of the Rey-Osterrieth Complex Figure (ROCF. Osterrieth. 1944; Rey, 1941) {see Appendix 1). The experimenter asked them to work together to copy the ROCF as accurately as possible on a single sheet of paper {encoding phase). To introduce different perceptions regarding the expertise and abilities of men and women, the task was presented to half the dyads as a "test of spatial orientation ability", and to the other half as a "test of interior decoration ability"-. The participants in each dyad were seated side by side at a table and were allowed to talk to each other during the test. Each one had a different selection of colored pencils to prevent social loafing (Karau & Williams. 1993) and also to identify their respective contribution within the dyad. There was a time limit of 3 minutes to complete this test, and during the test the experimenter left the room. Participants were then given two 2-mÍnute interfering tasks to avoid a recency effect: a vowel crossing-out test {Zazzo, 1972) and a letter comparison test^ (Salthouse. Fristoe. & Rhee. 1996). In the second session which followed immediately, the experimenter gave dyads one blank sheet of paper (with just the heading: "Test of spatial orientation ability"or "Test of interior decoration ability") and inslRicted them to draw the ROCF without the model {recall phase). Dyads were told that they would be evaluated for both speed and aeeuracy. To add a sense of urgency, an egg timer was put on the table. There was a time limit of two minutes, during which time the experirnenler left the room. As in previous studies (e.g., Myakovsky et al.. 2005), incentives for good performance were introduced by informing participants that the three best dyads would receive a cinema ticket. Dyads had no feedback of their performance during the experiment. After the reeall phase, tnembers of the dyads were separated and asked to complete a questionnaire. Finally, the partieipants were debriefed and the experimenter explained the objeetives of the study. Participants were invited to give the experimenter their email address or phone number so that they could be contacted if they had won a cinema ticket; each member of the best three dyads was indeed given a ticket a few weeks later. Dependent variable measures The dependent variables of interest in this experiment were dyad perfonnance on tbe ROCF task and the development of transactive memory system within dyads. Recall performance on the ROCF task. Task performance was scored by two research assistants, who were unaware of the hypotheses and had been trained to seore the ROCF task. The reliability of these scores was extremely high (lntraclass Correlation Coefficiem=.97), and therefore very satisfactory. Thus scores given by the two assistants were averaged to produce single scores for each dyad. The recall perfonnance was measured as suggested by Osterrieth (1944), and involved both the number and quality of units reproduced (26 units in this modified version of Rey's complex figure; see Appendix I). Two points were given if the unit was correct and properly positioned, 1 point if it was either altered but correctly placed, or GENDER ROLE AND TRANSACTIVE MEMORY 159 not altered but iticorrectly placed. 0.5 if it was altered and in the wrong place, and 0 if it was missing or unrecognizable. A perfonnance score was computed for each dyad as a sum ofthe scores on the ROCF task. The performance score ranged from 0 to 52 (maximum score: 26 units X 2 points). Higher scores indicate higher group performance. Member ratings ofthe Transactive Memory' System, in the final questionnaire, participants were asked to evaluate the group processes involved during the task, using a modified version ofthe Transactive Memory Scale (Lewis, 2003). The reliability and validity of ihis scale have been shown in both laboratory and field contexts, and it has been adapted into French for group leaming in a higher education context (Michinov, 2007; Miehinov & Michinov, 2009). This adapted French TMS scale contains 13 items instead ofthe 15 in the original scale (for examples of items, see Appendix 2). Each item was scored on a 5-poÍnt scale (\=strongly disagree, 5=strongly agree). In accordance with Lewis (2003). a TMS composite score was computed for each participant by summing scores on the 13 ilems (alpha=.7O), Higher scores indicated a stronger TMS development within dyads. To confirm that participants' seores eould be aggregated at the dyad level, we calculated the r^^ index (Cohen, Doveh, & Eick, 2001: James, Demaree, & Wolf, 1993), which measures the cfegrcc to which individual ratings within a dyad arc interchangeable. Mean r^^,g values of 0.70 or above provide evidence of acceptable agreement atnong members" responses (James et al,, 1993). For the present study, the average r^g was 0,65, with 69% ofthe r^g values above 0.70. Although this r^^.^ index was slightly below 0.70, the participants' responses to the TMS items were aggregated at the group level for statistical analyses. Results Experimental manipulation check The effectiveness ofthe task content manipulation was measured by a single item in the final questionnaire, whereby participants were asked to indicate what type of ability was tested (visuo-spatial orientation or interior decoration). A large majority of participants (98%) gave the correct answer. The manipulation of the gender of the group was not checked, the perception ofthe partner's gender being evident. Moderation effect of task content on performance of female and male dyads Our first hypothesis predicted an interaction effect between group gender and task content on performance. To test this hypothesis, we entered the variables into the regression analysis in two steps: (1) ihe effects of main variables (i.e.. Group gender and Task content), and (2) the interaction term (Group gender x Task content)'*. The results are summarized in Table I (see Model 1). The first step of analysis yielded no effect of task content (/^.13, ns), and only a marginal main effect of Group gender \jd=.25, /(43)=1.69, p=.O9], indicating ihat performance tended to be higher in female dyads (A/=^32.42, 5'D=7.3O) than in male dyads (W=29.20, 5'D=9.00). The second step ofthe analysis provided support for Hypothesis I: a significant Group gender by Task content interaction clearly occured (ß=-.l>2, /(43)=-2.16, /j=.O37). Figure 1 shows the pattern of this interaction. As expected, separate tests for simple effects in each task condition showed that mate dyads performed lower when the task was characterized as masculine (A^24.8I, 5£>=8.90) than when it was characterized as feminine (M=32.I2, 50=8.16),/?=.4I, /(19)-1.89, p<.05. Conversely, contrary to our expectations, female dyads performed at the same level on a feminine task (A/=31,0, 5D=8.11) and a masculine task (A^34.09, SD=b.2Q),ß=-.22. /(23)=-1.03, ns. The first hypothesis conceming the combined effect of group gender and task content on group performance was therefore only partially supported. E. MICHINÜV, N. MICHINOV, & P. HUGUET 16Ü Gender group Female Feminine Task Figure I. Mean recall performance as a function of group gender and task eontent Moderation effect of task content mediated by Transactive Memory System Our second hypothesis predicted that the interaction effect between group gender and task content on performance would be mediated by the transactive memory system. To test this hypothesis, we carried out a mediated moderation analysis (cf. Muller, Judd, & Yzerbyt, 2005; Preacher, Rucker, & Hayes, 2007). According to Baron and Kenny (1986) and Müller et al. (2005), three conditions must be met to test a mediated moderation: (a) the coefficient associated with the interaction term (i.e.. Group gender x Task content) should significantly affect the dependent variable (i.e., Performanee; see Model I above); (b) after controlling for the other predictor variables, the coefficient associated with the interaction tcmi should affect the mediator (i.e.. Transactive memory; Model 2), and after controlling for the Mediator x Moderator tenn and the other predictor variables, the coefficient associated with the mediator should significantly affect the dependent variable (see Model 3); finally (c) after controlling forthe mediator, the coefficient associated with the interaction term on performance should be lower in magnitude (partial mediation) or become non-significant (complete mediation). The regression models used to test the effect of mediated moderation are summarized in Table 1. Table 1 Summary of regression analysis results Predictors IV: group gender Moderator: task cotitent !

The introduction of the mediator by moderiiiioii interaction term is necessary' to make ä distitietion between these two case.s (see Müller et ai., 2005). +p<.lQ:'f><-.05.*'p<.0\. 161 GENDER ROLE AND TRANSACTIVE MEMORY The results only partially verify the mediated moderation hypothesis, and. as we can see in Table 1. the three models are not all supported. Model 1 (testing our Hypothesis I) was supported, as already described above showing the moderation effect of task content on perfomiance of male and female dyads. Model 2 was not supported however. It showed that the interaction between group gender and task content did not affect the mediator variable (i.e., transactive memory system). Only a marginal effect of group gender on transactive memory was found {/J=.2S.. t (43)= 1.8!. /»=.O78). indicating that the transactive memory system tended to be more developed in female dyads (W=56,85. SD=4.97) than in male dyads (M=55.37, 5D^4,08). In model 3, we predicted that the coefficient associated with the moderation effect (Gender group x Task content) would be reduced or eliminated after controlling for the effect of the mediator variable (i.e.. tuuisaetive memory). The results did not support this prediction. Indeed, we observed a significant regression coefficient associated with the moderation effeet (/^-.44, t (43)=-3.I4,/J=.OO3) on performance after controlling for the mediator effect of transactive memory {ß=.31, t (43)=2.67, p=.0\ I) and the interaction between transactive memory and task content (/?=.3O, / {43)=2.1S, p=.O35). Thus, transactive memory did not mediate the moderation between group gender and task content. Simple mediation effect of transactive memory. To explore in depth the marginal effects of group gender on performance (sec Table 1. Model I) and on TMS scores (see Table I, Model 2), we carried out a simple mediation analysis in which group gender was the predictor variable, group performance was the outcome, and transactive memory was the mediator (see Eigure 2). Eirst. the analysis revealed a marginally significant relationship between the predictor (group gender) and the outcome (group performance). (/?=.23, /(43)^I.5O, /j^.IO). The relationship between the predictor and the mediator (transactive memory) was significant {/h.3O. /(43)=1,96,/J=.O5), as was the link between the mediator (transactive memory) and the outcome (group performance) after controlling for the effect of group gender [ß'-.31, í(43)=2.18./7-.O35). The effect of group gender on performance became non-signitlcanl when the mediator (transactive memory) was entered into the equation (/í^.lO, ns). Even though SobePs test was not significant-^, the diminution of the beta provided some support for a partial mediation effect of TMS on the relationship between group gender and performance. /!= .37* Oroup Gender tiroup perfomianco /î=,10. n.v F/gwre 2. Mediation model of the role of transactive memory in explaining the impact of group gender on performance Note- +p<M)\-p<.05\"p<.Q\. Discussion The goal of this experiment was to examine the combined influence of gender role and task content on group perfonnancc. looking at transactive memory as a potential mediator of this moderation effect. Based on recent flndings in the framework of Social Role Theory (e.g., Karakowsky & Siegel, 1999; Miller & Karakowsky, 2005). our first hypothesis predicted that female dyads in a collaboralive setting would activate communal allribuies and would achieve 162 E. MICHINOV, N. MICHINOV, & P. HUGUET better performance, especially in a feminine task. Conversely, maies collaborating in dyads would activate agentic attributes and achieve poorer collective performance, especially in a masculine task. As predicted, an interaction effeet was found between group gender and task content on group performance, with male dyads obtaining poorer recall performance scores than female dyads when the task was supposedly a masculine task. This result supports recent studies carried out in the framework of social role theory (e.g., Karakowsky & Siegel, 1999; Miller & Karakowsky, 2005; Myaskovsky et al., 2005) which found that agentic characteristics occur more frequently among men in same-gender groups, and particularly when the gender orientation of the task is congruent with the gender of the performer (i.e., masculine task). However, contrary to our expectations, female dyads did not perform better when collaborating on a congruent feminine task. It seems that whatever the nature of the task, female dyads activate communal characteristics and consequently achieve better collective performance in same-gender leaming groups. Another explanation of these findings could arise from studies in another domain which suggest that the gender composition of the context in which performanee is measured could constitute a stereotype threat among women (Huguct & Regner, 2007; Inzlicht & Ben-Zeev, 2000; Sekaquaptewa & Thompson, 2003). For example, in Inzlicht and Ben-Zeev's (2000) study, women's performance on a math test was found to be lower when they were asked to take the test with a majority of men than when they worked in a same-gender setting (see also Sekaquaptewa & Thompson, 2003). Likewise, in a more normal classroom context, Huguet and Regner (2007) found that school girls working alone or in mixed-gender groups (i.e.. with mixed-gender classmates) performed poorly when they were led to believe that the task measured mathematical skill. However, this deficit was not observed in same-gender groups (i.e.. with only same-gender classmates). Contrary to our second hypothesis, the results of the mediated moderation analysis indicated that the moderation effect was not mediated by the development of a transactive memory system. Instead, results provide evidence for a simple mediation cfíect of transactive memory on the relationship between group composition and performance. It seems that women arc more likely to cooperate and develop transactive memory than men. and this transactive memory system eould lead to better joint performance. Several explanations ean be put forward to explain our findings. The first explanation is related to general differences in social orientation between males and females (e.g., Eagly, 1987; Miller & Karakowsky, 2005; Wood, 1987). Women often have a more collectivist orientation (i.e., cooperative, interdependent or communal self-concept), while men exhibit a more individualist orientation (i.e., eompetitive, independent or agentic self-eoneept). Women are less likely to reduce their efforts for the group and exhibit a lower degree of social loafing (Karau & Williams, 1993), whereas men, by striving to be better than others using social comparison strategies (Karakowsky & Siegel. 1999). demonstrate the reverse pattern, regardless of the consequences for the group outcome, lt is possible that men are more eompetitive than women and show a tendency towards ego-defensiveness when they compare themselves with each other (Karakowsky & Siegel. 1999). Although this interpretation is speculative, because we did not specifically measure ego-defensiveness and social comparisons within groups, future research should assess these aspects and the relationship with transactive memory processes more directly (see Miller & Karakowsky, 2005). Such differences in communal and agentic attributes between women and men may explain why certain gender differences were observed in the development of transactive communication and transactive memory. Moreover, men are more likely to exhibit competitive behavior when the task is relevant for their self-definition than when it is irrelevant (cf. Huguet & Monteil, 1995), and the competitive social behavior among men during the test of spatial orientation ability (i.e., stereotypically masculine task) may in fact have interfered with the development of transactive memory, and consequently with group performance. Furthermore, this eompetitive attitude among men may have occurred because they did not have time to get to know each other when carrying out a time-limited task. Some recent findings with groups of students performing a series of real academic tasks spread over time have demonstrated that transactive memory develops differently over time (Michinov & Michinov., 2009). The performance of women and GENDER ROLE AND TRANSACTIVE MEMORY 163 men on a masculine task may be similar if they have to carry out similar tasks spread over time or a longer collaborative task. Consequently, fijture studies should examine the development of transactive memory in male and female dyads over time in greater depth. Although the present experiment provides some evidence for the combined effects of task content and group gender on group performance, and the potential mediation effeet of transaetive memory on the relationship between gender and performanee, a number of limitations and unanswered questions need to be highlighted. The first limitation concerns the issue of generalizability arising from the nature of the sample chosen; the male participants were mostly students in psychology, the arts or humanities. This raises the question of whether the same gender differences would have been observed with seienee students. Some studies (Chatard, 2004; Guimond & Roussel, 2002) have in faet demonstrated that the choice of academic orientation reflects gender stereotypes. Thus, gender stereotypes about the abilities of men and women in the arts (i.e., a stereotypically feminine domain) and mathematics (i.e., a stereotypically masculine domain) occur among university students and influence their performanee expectations. Such fmdings suggest the need to examine the combined effects of gender stereotype, task content and group composition with students following scientific programs, A second limitation concerns the method used to measure transactive memory. Although the validity of the transactive memory scale (Lewis, 2003; Michinov, 2007) has been attested, this indirect measure was carried out as a post-experimental questionnaire after the interactions between partners. In faet, transactive memory should be assessed while the tasks are being carried out, through observation and coding of behaviours and verbal interactions. Although more costly for researchers than questionnaires, video recording assessments already exist (Hollingshead, 2001; Liang, Moreland, & Argote, 1995; Moreiand, 1999) and should be used in future studies. To conclude, the present study provides an initial experimental examination of the eombined effect of group gender and task orientation on the distribution of expertise among students. We hope that the present fmdings will eneourage educational researchers to carry out further investigations into group composition using different criteria (e.g., gender, ethnicity, social class) and its impact on interpersonal behaviour, group processes and performance to optimize group learning activities in educational settings.

Notes 1 While (ransactive memory refers to memory held at the individual level, the transactive tnemory systetn (TMS) describes how group members actively use their transactive memory to encode, store, and retrieve information at a group level (Lewis, lOt).!), 2 To assess the gender-oriented task, a pre-test was conducted with 100 students (4X male and 52 female). The students were asked to estimate their perceptions regarding the gender orientation of !he two tasks on a 5-point scale (l=primarily men to .''=primarily women). The resuits ofthe pre-test confirmed that the two tasks are differently perceived regarding iheir gender orientation. Specifically, one sample t-test analysis (different from Ihe value 3) revealed that men were marginally perceived as more expert and knowledgeable ihan women regarding the spatial task {M=2.3<^. SD=0.^2. /(99)=-7.8û./X.Ü7), By contrast, women were perceived as more expen and knowledgeable than men regarding the decoration task(A^4,l4, SD=O.7I./(99)=lh.06.;)<.05), i The paper-anti-penLJl version ofthe Letter Comparison Test (Salthouse et al.. 1996) consisted of a page containing pairs of letter strings with 3, 6, or 9 letters (e.g., OXL OXL) presented in random onjer. Participants had to indicate wheiher the two strings of letters were the same or different. 4 To reduce any potential problems of multicollinearity, we centered the variables before calculating the interaction terms (Aiken& West. 1991). 5 One ofthe assumptions necessary for the Sobel-lest is that the sample size is large (cf.

GENDER ROLE AND TRANSACTIVE MEMORY 167 L 'objectif de cette expérience était d'examiner les effets des râles de genre et de la connotation stéréotypique de ¡a tâche sur la performance de groupes d'apprenants, ainsi que l'effet potentiel d'un processus médiateur relié à la mémoire transactive. 44 dyades (dyades masculine vs. féminine) étaient invitées à participer à une tâche d'apprentissage connotée sexuellement (féminine vs. masculine) en situation de laboratoire. Des mesures de performance collective et de mémoire transactive étaient recueillies. Conformément à nos hypothèses, les résultats ont montré une interaction entre ¡a composition des dyades et la connotation de la lâche sur la performance collective, montrant que ¡es performances des dyades masculines sont plus faibles que celles des dyades féminines lorsque la tâche d'apprentissage est connotée masculine. Toutefois, contrairement aia attentes, cet effet d'interaction entre la composition des dyades et la connotation de la tâche n 'est pas médiatisé par le processus de mémoire transactive. En effet, celui-ci apparaît comme un simple médiateur de lu relation entre la composition des dvades et la performance collective. Les résultats sont discutés dans le cadre de ¡a théorie des râles sociaux. Les implications pour ¡es recherches futures sur les groupes d'apprentissage sont également proposées.
