Recent findings indicate that frontal brain asymmetry may be a marker of for depression. However, the psychological predispositions that account linkage between frontal brain asymmetry and depression are unclear. approach-withdrawal hypothesis is the primary framework that has been to account for the linkages between frontal brain asymmetry and or emotional disorders. We review evidence consistent with this and suggest several directions for its extension. One such direction is to constrain the approach-withdrawal hypothesis by linking frontal asymmetry to the known functions (...) of the prefrontal cortex. On this we propose that frontal brain asymmetry may be preferentially linked processes that promote the temporal continuity and shifting of or emotional priorities and the suppression of interference by sources of motivation or emotion. We review evidence from and neurobiological studies of depression that is broadly consistent with these predictions. We emphasise the need for future studies testing our hypotheses. (shrink)

Using a paradigm that allows a quasi-continuous tracking of memory performance over time, two experiments were designed to test the hypotheses that persons with a cognitively avoidant style of coping with threat manifest a dissociation between short-term and long-term retrieval of aversive information and persons with a vigilant coping style recall aversive information particularly well after long retention intervals, provided they are free to think about aversive events. Study 1 showed that avoiders manifest a poor memory for aversive pictures after (...) long retention intervals only. Study 2 replicated this finding. In addition, manipulation of the cognitive load during the retention interval influenced vigilants’ recall of aversive information in the predicted way. Results indicate that processes occurring during the retention interval are essential for individual difference in memory for aversive information and require similar attention as encoding, appraisal, and retrieval processes.
