Perceived group variability and dispositional need for closure

Based on the closure motivation theory proposed by Kruglanski and Webster (1996), it was hypothesized that the extent of perceived variability of target group members would be related to dispositional need for closure. Israeli teachers (n = 160) judged their professors by means of two methods and answered the need for cognitive closure questionnaire (NFCS, Webster & Kruglanski, 1994). The findings show that need for closure is related to social judgment. The perception of participants high in need for closure was less differentiated and more extreme, in comparison to participants low in need for closure. Findings also yielded that measures of variability are method dependent.
