AbstractThe avoidance theory of worry (Borkovec, Alcaine, & Behar, 2004) posits that the verbal-linguistic (versus imagery-based) nature of worry elicits abstract (versus concrete) processing, which inhibits affective responding and generates a host of negative consequences. Although suppression of worrisome thinking is maladaptive (Purdon, 1999), expression of worry using vivid imagery may increase concreteness of worrisome thinking and facilitate more adaptive emotional responding. The present study examined whether the valence, content, and expression of mentation impacts concreteness of thought. Participants (N = 62) were randomly assigned to verbalize their thoughts while engaging in either verbal-linguistic- or imagery-based mentation about both worrisome and neutral topics. Participants were also randomly assigned to engage in a 5-min period of suppressing or expressing the target stimuli before engaging in 5-min of freely expressing the targets. Verbalizations of mental content were coded for level of abstractness/concreteness. For neutral stimuli, imagery-based mentation led to greater concreteness than did verbal-linguistic mentation; however, for worrisome stimuli, imagery-based mentation did not enhance concreteness. In addition, for neutral (but not worrisome) stimuli, an initial period of suppression was associated with increased concreteness during subsequent expression. Imagery-based mentation about worrisome stimuli may not enhance concreteness; moreover, unlike suppression of neutral stimuli, suppression of worrisome stimuli may maintain, rather than ameliorate, abstractness of thought.Published by Elsevier Ltd.
