Abstract:
This experiment examined how (disrespectful vs. respectful) treatment and (negative vs. positive) performance evaluation, both received from the same fellow group members, affects collective identification and willingness to engage in group-serving behavior. It was predicted and found that respectful as opposed to disrespectful intragroup treatment increased collective identification and willingness to engage in group-serving behavior in the immediate group situation, irrespective of whether intragroup evaluation was positive or negative. There was also evidence of a mediating role of collective identification. Regression analyses based on the measurement of perceived intragroup treatment and perceived intragroup evaluation as continuous variables corroborated these findings but also pointed to limits of the positive effects of respectful intragroup treatment. Finally, the interrelation of treatment and evaluation by fellow group members as two possible components of intragroup respect are discussed as well as the political dimension of research on intragroup respect.
