Upper level college students in the United States (N = 28) were presen
ted with vignettes describing a manager as possessing either (a) high
coercive and reward power, or (b) low coercive and reward power. The m
anipulation of these two power bases had a significant impact on all f
ive of French and Raven's (1959) power bases (i.e., referent, coercive
, expert, legitimate, and reward). Moreover, population effect size es
timates (eta-squares) were noticeably large, ranging from .17 to .68.
These findings are interpreted utilizing a cognitive perspective, and
expanding the construct of cognitive structures to the realm of social
power.
