title: Affective ratings and startle modulation in people with nonclinical depression.
abstract: This study tested predictions based on the emotion context insensitivity (ECI) hypothesis of Rottenberg, Gross, and Gotlib (2005) that a nonclinical sample of people with depressive symptoms would show reduced responses to both positive and negative stimuli relative to people without depression and would show an enhanced response to novelty. Seventy individuals completed diagnostic questionnaires, made ratings of 21 affectively valenced pictures, and then viewed the same 21 pictures and 21 novel pictures while startle blink responses were recorded from electromyographic activity of the orbicularis oculi. People with scores on the Beck Depression Inventory (BDI; Beck, Ward, Mendelson, Mock, & Erbaugh, 1961) indicative of depression demonstrated a lack of affective startle modulation compared to the nondepression group. For all participants, the startle response was larger for novel pictures than for previously viewed pictures, but scores on the BDI were not related to response to novelty. Taken together, the results suggest that nonclinical depression is associated with a lack of affective modulation of startle, as has been shown for clinical depression.
