This study tested the validity of hostile attributional bias as a cogn
itive correlate of anger/aggression in adults. Findings generalized ho
stile attributional bias into adult populations in ambiguous situation
s, and extended the construct into benign and hostile situations. Supp
ort was seen for the notion that hostile attributional bias is a separ
ate functional entity from simple attribution of intentionality in neg
ative social interactions, with some indication of a tiered cognitive
process - attributing first intentionality then hostility of intent. F
orced cognitive mediation was seen to have greater effect on angry res
ponse in ambiguous situations for aggressive than nonaggressive subjec
ts. The findings are discussed in light of relevant cognitive-behavior
al and social information processing theories.
