Induced processing biases have causal effects on anxiety

After briefly describing the nature of emotional processing biases associated with vulnerability to anxiety, and a model of how they may be produced, we review new data on the experimental induction of attentional and interpretative biases. We show that these biases can be readily induced in the laboratory, in the absence of mood changes. However, induced biases exert effects on the processing of new information and cause congruent changes in state anxiety when they influence how emotionally significant information is encoded. We can therefore conclude that biases have causal effects on vulnerability to anxiety via their influence on how significant events are processed. Finally, we discuss how our model might account for the acquisition of processing bias and for when they can influence anxiety.     

Biased interpretation in perfectionistic concerns: an experimental investigation

Background and objectives: Perfectionism is associated with the development and maintenance of several disorders. Given the importance of perfectionism understanding the biased information processes that underpin it is critical. The present study tested the hypothesis that heightened concern over mistakes subscale scores of the Frost Multidimensional Perfectionism Scale are characterized by a tendency to impose emotionally negative interpretations on perfectionism-relevant situations.

Method and design: Seventy-six non-clinical, general population participants’ were presented with interpretations of scenarios where a protagonist was described as achieving well above what was required, but fell short of their own high standard. Using a within-subjects, quasi-experimental design, we assessed interpretations of these scenarios by examining the degree to which participants rated test sentences as being likely implications of the original scenarios.

Results: A generalized linear mixed model revealed higher concern over mistakes scores were associated with an increased tendency to rate negative target test sentences as being similar to the original perfectionism-relevant scenarios, and a reduced tendency to rate positive target test sentences as being similar to these original scenarios.

Conclusions: The findings provide support for the cognitive–behavioral model of perfectionism. These findings support the inclusion of strategies in cognitive–behavioral treatment of perfectionism to reduce interpretation bias.
