A wide range of studies supports the conclusion that people defend themselves against threats by mentally isolating them. Repressors have been shown to process information in a rushed, shallow, or minimal fashion. When presented with some negative information, they will often generate spontaneous happy thoughts or feelings, minimizing its impact. Depressed people process information much more thoroughly, whether it is good or bad. This high level of processing develops strong associative links with similar information. When a depressed person tries to avoid a damaging cognition, they often think of some other negatively affecting thought. Evidence from human and animal studies shows that isolation prompts sensitivity to social threats and motivates the renewal of social connections.
