The rationale underpinning the diagnosis of acute stress disorder is that cognitive mechanisms result in avoidant processing of aversive experiences. This study investigated acutely traumatized participants with either acute stress disorder (ASD; n = 15) or no ASD (n = 14) and nontraumatized comparison participants (n = 16). Participants were administered intermixed presentations on a computer screen of positive, neutral, and trauma-related words that were followed by instructions to either remember or forget each word. On a subsequent recall test, ASD participants displayed poorer recall of to-be-forgotten trauma-related words than did non-ASD participants. Severity of psychopathology was negatively correlated with to-be-remembered positive words. These findings are consistent with the proposal that people who develop ASD display an aptitude for superior forgetting of aversive material.

Acute stress disorder is characterized by dissociative responses that are theorized to result in deficient encoding and retrieval of trauma-related material. This study examined retrieval inhibition using the list method of the directed forgetting paradigm in traumatized individuals with acute stress disorder (ASD; n = 14), no ASD (n = 14), and a nontraumatized control group (n = 15). Participants were presented with a list of intermixed positive, neutral, and trauma-related words. Instructions to forget that list and instead remember a second list were then given, and a new list presented. ASD participants exhibited poorer recall of to-be-forgotten trauma words than the non-ASD and control groups. The ASD group also demonstrated deficient recognition of to-be-remembered and to-be-forgotten positive words. Severity of acute posttraumatic stress response was associated with retrieval impairments. The cumulative findings suggest that ASD is associated with impoverished memory for trauma-related and positive material.

The decline in self-related memory in ASD was investigated by using encoding, forgetting, and source monitoring. Participants memorized action sentences verbally, observationally, or by enacted encoding. Then, they underwent recall, recognition, and source monitoring memory tests immediately and 1 week later. If the information were properly encoded, memory performance in the enacted encoding would be the highest (enactment effect). The result of memory tests in ASD and TD people showed that enacted encoding was superior. However, recall and source monitoring in ASD was significantly lower than in TD, which was not the case for recognition and forgetting. These results suggest that the decline in memory of self in ASD is associated with a deficit in memory reconstruction and source monitoring.
