Previous empirical and theoretical work suggests differences among attachme
nt types with regard to their openness in perceiving and organizing social
information. To examine these hypothesized differences, participants were g
iven two sets of information characterizing the same target person, one set
depicting an insecurely attached person, the other portraying a securely a
ttached person. Proposed differences in openness to incorporating new infor
mation, differentiation in cognitive representations of others, and recall
were assessed. As hypothesized, avoidant individuals were less open to new
information than were secure subjects, and they differentiated their repres
entations less than did both secure and anxious-ambivalent individuals. Mor
eover, as expected, there were no significant differences between secure an
d anxious-ambivalent individuals on the dimensions of openness and differen
tiation. However, avoidant individuals did not evidence poorer recall of th
e stimulus material. Theoretical and clinical implications of avoidant indi
viduals' relatively more rigid, simplistic models of others are explored.
