Attachment theorists propose that individuals’ internal working models influence their social information processing. This study explored links between attachment representations and social information processing by examining adolescents’ (n = 189; Mage = 16.5 years) attachment-related memory biases. Participants completed laboratory tasks assessing memory for (a) emotionally salient childhood events, (b) adjectives describing their parents, and (c) generalized parent-related characteristics not specific to their own parents. As expected, dismissing attachment (assessed using the Adult Attachment Interview) was linked across tasks to a deactivating strategy in which memory for emotional childhood events and attachment-relevant stimuli was reduced. In contrast, evidence that preoccupied attachment was linked to a hyperactivating strategy in which memory was heightened emerged only in relation to emotional childhood events.
