Abstract：
:The affect-modulated startle response is a reliable indicator of the affective processing of stimuli. It may be influenced by trait and state affective variables as well as psychopathological status. The aim of the present study was to determine the influence of the current mood state on startle modulation. Forty-five healthy volunteers viewed affective stimuli while eye blink responses and subjective emotional ratings were assessed. In addition, the current state of mood was assessed, pre and post the experimental procedure. Subjects were divided into those that were in a more positive and those that were in a more negative mood based on a median split. Compared to subjects in a positive mood those in a more negative mood showed significantly reduced startle amplitudes after viewing the negative and neutral stimuli. The results of the present study show that changes in startle responses are not only related to the current state of psychopathology but also to the general affective state of the participants during the assessments.
