Can people's tendency towards aggression distort their memory for ambiguous information? We investigated the effect of subjects‚ recall for an ambiguous list containing words that could be interpreted as describing either an aggressive or non-aggressive theme. Subjects read lists of associated words-- but half read a list of insult words immediately before presentation of the ambiguous list. The other half read only neutral lists. Both highly aggressive subjects and insulted subjects were more likely to falsely report that the ambiguous list contained at least one violent non-presented word, compared to low aggressive and non-insulted counterparts. Our results suggest that a propensity towards aggression can bias processing and interpretation of ambiguous information.
