Additional analyses. The collective motive versus the individual motive. In both the high respect condition and the average respect condition, participants showed enhanced levels of affective commitment when compared with participants in the low respect condition (see Table 5). To confirm our predictions that when people are respected, enhanced feelings of affective commitment will be related to more engagement in discretionary group efforts, we subjected affective commitment, situational group attachment an>iety, and discretionary group efforts to linear regression analyses. Linear regression analysis within the relevant conditions (i.e. the high respect condition and average respect condition) showed the following: After having received higher or average respect, when both affective commitment and situational group attachment an>iety were in the equation, only affective commitment, R2ch = .06, β = .25, t(2,90) = 2.48, p < .05, revealed a significant relation with the discretionary group efforts measure, whereas situational group attachment an>iety showed no significant relation to the discretionary group efforts measure, R2ch = .02, β = .12, t(2,90) = 1.22, p = .23 (see Figure 1). Figure 1 Results of linear regression analysis of Discretionary Group Efforts on Affective Commitment and Situational Group Attachment Anxiety when Respected or Disrespected Discretionary group efforts Affective commitment β = .25* When respected (the collective motive) Situational group attachment anxiety β = .12ns When disrespected (the individual motive) β = .02ns Discretionary group efforts Affective commitment Situational group attachment anxiety β = .31* Note. * = significant at p < .05 ns = not significant By contrast, participants in the low respect condition indicated to have more feelings of situational group attachment an>iety compared to participants in respectively the high respect condition or average respect condition (see Table 5). To further support our assumption that when people perceive themselves as disrespected, displays of discretionary group efforts will appear due to higher levels of situational group attachment an>iety for those in the disrespected condition, we subjected affective commitment, situational group attachment an>iety, and discretionary group efforts to linear regression analyses. Within the disrespect condition when both affective commitment and situational group attachment an>iety were in the equation, instead of affective commitment, R2ch = .01, β = .02, t(2,42) = .15, p = .89, this time only situational group attachment an>iety R2ch = .09, β = .31, t(2,42) = 2.03, p < .05, related significantly to the discretionary group efforts measure (see Figure 1). This indeed provides further evidence for our reasoning that whereas respected people engage in discretionary group efforts motivated by their affective commitment to the group, disrespected people engage in similar group supportive behavior motivated by the situational group attachment an>iety they e>perienced.
