Examining Mental Imagery and Post-event Processing among Socially Anxious Individuals

Abstract

Social anxiety disorder (SAD) is characterized by an intense fear of negative evaluation from others in social and/or performance situations. Research has demonstrated that socially anxious individuals' post-event processing, or post-mortem review of social situations, often affects their levels of anxiety, negative emotions, interpretations, and memories of events (Brozovich & Heimberg, 2008). Furthermore, research has shown that processing negative descriptions using imagery is more emotion-evoking than semantic processing of the same material (Holmes & Mathews, 2005; Holmes & Mathews, 2010). The present study investigated post-event processing involving mental imagery and its effects on mood, anxiety, and potentially biased interpretations of social and nonsocial events. Socially anxious and non-anxious participants were told they would give a 5 min impromptu speech at the end of the experimental session. They were then randomly assigned to one of three manipulation conditions: post-event processing imagery (PEP-Imagery), post-event processing semantic (PEP-Semantic), or a Control condition. In the post-event processing conditions, participants recalled a past anxiety-provoking speech and thought about the anticipated speech either using imagery (PEP-Imagery) or focusing on their meaning (PEP-Semantic). Following the condition manipulation, participants completed a variety of affect, anxiety, and interpretation measures. Consistent with our predictions, socially anxious individuals in the PEP-Imagery condition displayed greater anxiety than individuals in the other conditions immediately following the induction and before the anticipated speech task. Socially anxious individuals in the PEP-Imagery condition also interpreted ambiguous scenarios in a more socially anxious manner than individuals in the Control condition. The impact of imagery during post-event processing in social anxiety and its implications for cognitive-behavioral interventions are discussed.
