Abstract

Affective reactions to briefly presented pictures were investigated to determine whether fleeting stimuli engage the motivational systems mediating emotional responses. Emotional and neutral pictures were presented for 500 ms: heart rate, skin conductance. corrugator EMG. and the evoked startle reflex were measured. The time course of reflex modulation was similar to thatobtained with longer (6 s) presentations, suggesting that picture processing continues in the absence of a sensory stimulus. Affective reactions found with more sustained presentation were also obtained, with more corrugatorEMG activity for unpleasant pictures, and greater skin conductance reactivity for emotional pictures. Heart rate modulation, however. appears to relyon the presence of a sensory stimulus. The data also suggest that brief presentations of unpleasant pictures may result in less defensive activation than sustained presentation.
