Depression impairs the ability to ignore the emotional aspects of facial expressions: Evidence from the Garner task

We assessed dysphoric and clinically distressed individuals' ability to ignore the emotional aspects of facial expressions using the Garner speeded‐classification task. Garner's paradigm tests the ability to selectively focus on a single relevant dimension while ignoring variations on other, irrelevant, ones. In the present task, the stimuli were faces of men and women expressing happy, angry, and neutral emotions. In Experiments 1 and 2, dysphoric and nondysphoric participants performed the Garner task, focusing on gender and ignoring emotion (Experiment 1) and focusing on emotion and ignoring gender (Experiment 2). Results suggest that dysphoric individuals exhibited more difficulty ignoring the emotional dimension of social stimuli even under specific instructions to do so than nondysphoric individuals. In Experiments 3 and 4, we replicated these results in clinically distressed and nondistressed individuals. The results of Experiment 3 further suggested that depression was more closely associated with the inability to selectively ignore emotion than was social anxiety. Experiment 4 confirmed that this failure of selective attention was specific to processing emotional, and not gender features. The implications of these findings for cognitive and interpersonal theories of depression are discussed.     

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.     

The relationship between the structural mere exposure effect and the implicit learning process

Three experiments are reported that investigate the relationship between the structural mere exposure effect (SMEE) and implicit learning in an artificial grammar task. Subjects were presented with stimuli generated from a finite-state grammar and were asked to memorize them. In a subsequent test phase subjects were required first to rate how much they liked novel items, and second whether or not they thought items conformed to the rules of the grammar. A small but consistent effect of grammaticality was found on subjects' liking ratings (a "structural mere exposure effect") in all three experiments, but only when encoding and testing conditions were consistent. A change in the surface representation of stimuli between encoding and test (Experiment 1), memorizing fragments of items and being tested on whole items (Experiment 2), and a mismatch of processing operations between encoding and test (Experiment 3) all removed the SMEE. In contrast, the effect of grammaticality on rule judgements remained intact in the face of all three manipulations. It is suggested that rule judgements reflect attempts to explicitly recall information about training items, whereas the SMEE can be explained in terms of an attribution of processing fluency.
