    Abstract

    Several studies have investigated the effects of depression on the intensity and frequency of facial displays. Comparativly little research has investigated dynamic aspects of facial displays in depression such as timing. The aim of the study was to investigate the effects of depression on the timing of smiles by measuring latency and related timing characteristics in the production of positive facial displays in response to stimuli intended to elicit positive emotion. Results represent the first evidence fo the effects of bipolar disorder on the timing characteristics of smiles. Results also suggest that the presence of dampening actions during smiles is related to depressive symptomatology.
