Judgement of facial affect among depressives and schizophrenics.

Forty depressives, 48 schizophrenics and 105 non-patient controls were asked to judge the mutual similarities amongst six different facial affects depicted in photographs. Inter-stimulus distances suggest two dimensions of affect operative in controls: pleasantness-unpleasantness and arousal-non-arousal. Depressives' judgements correspond to the former dimension whilst schizophrenics' judgements correspond to the latter.
