The association between ruminative thinking and negative interpretation bias in social anxiety.

Cognitive models propose that both, negative interpretations of ambiguous social situations and ruminative thoughts about social events contribute to the maintenance of social anxiety disorder. It has further been postulated that ruminative thoughts fuel biased negative interpretations, however, evidence is rare. The present study used a multi-method approach to assess ruminative processing following a social interaction (post-event processing by self-report questionnaire and social rumination by experience sampling method) and negative interpretation bias (via two separate tasks) in a student sample (n = 51) screened for high (HSA) and low social anxiety (LSA). Results support the hypothesis that group differences in negative interpretations of ambiguous social situations in HSAs vs. LSAs are mediated by higher levels of post-event processing assessed in the questionnaire. Exploratory analyses highlight the potential role of comorbid depressive symptoms. The current findings help to advance the understanding of the association between two cognitive processes involved in social anxiety and stress the importance of ruminative post-event processing.

Exercise and Memory.

Our memory is crucial to our daily functioning, our identity, and how we interact with the world around us. Maintaining memory functioning is therefore important in many ways. Exercise positively affects our memory. Even a single exercise session can directly boost different memory types, including working, procedural, and episodic memory. Due to these benefits, exercise has great potential as an intervention in different settings, such as schools or rehabilitation centers, and as a prevention strategy. In this chapter, we first give an overview of what memory is and why it is so relevant to our mental health. Next, we briefly discuss how, for whom, and under which circumstances exercise improves memory functioning. Then, we will summarize the literature of experimental studies investigating the direct effect of exercise on different memory types, while acknowledging current limitations and potential future directions. Finally, we briefly highlight the potential of exercise as intervention to preserve and improve memory.
