Obsessive beliefs predict cognitive behavior therapy outcome for obsessive compulsive disorder

Cognitive accounts of obsessive compulsive disorder (OCD) assert that core beliefs are crucial to the development, maintenance, and treatment of the disorder. There are a number of obsessive beliefs that are considered fundamental to OCD, including personal responsibility, threat estimation, perfectionism, need for certainty, importance of thoughts, and thought control. The present study investigated if pretreatment severity of obsessive beliefs, as well as the change in obsessive beliefs following treatment, predicted intensive, residential cognitive behavioral therapy (CBT) treatment outcome. A series of hierarchical regression analyses were carried out to investigate the relations between obsessive beliefs and treatment outcome. Results indicated that inflated pretreatment responsibility/threat estimation beliefs were significantly related to less overall obsessive compulsive (OC) symptom reduction at discharge, explaining 2% of the overall variance. Changes in obsessive beliefs broadly, and importance/control of thoughts specifically, were positively related to overall OC symptom reduction at discharge, respectively explaining 18% and 3.6% variance. Results are modestly consistent with a number of theoretical models, which argue that inflated responsibility, threat estimation, and thought control are important to the maintenance and treatment of OCD.     

The Functional Forecast Model of Emotion Expression Processing

Fleeting nonverbal emotion expressions trigger a variety of spontaneous responses in human observers. To account for these effects, we introduce a functional forecast model (FFM) of emotion expression processing. The FFM assumes that emotion expressions provide timely forecasts of impending events. Responses to these forecasts are adaptive and may be learned or innately prepared, but in either case, observers need not infer mental states to exhibit immediate responses to emotion expressions. We postulate a diffuse route that operates pre‐attentively and activates appetitive and defensive motivational systems in response to gross affective meaning relevant to imminent environmental threats and available or scarce survival resources. We postulate a focal route that requires attention to efficiently and spontaneously activate specific, though tacit behavioral expectations. We explain how the FFM accounts for a variety of responses to emotion expressions, including physiological responses, affective responses, behavioral responses, trait attributions, and emotion recognition. Lastly, we describe how the FFM relates to other models of emotion, and describe future directions based on the model.     

Attentional sensitization of unconscious visual processing: Top-down influences on masked priming

Classical theories of automaticity assume that automatic processes elicited by unconscious stimuli are autonomous and independent of higher-level cognitive influences. In contrast to these classical conceptions, we argue that automatic processing depends on attentional amplification of task-congruent processing pathways and propose an attentional sensitization model of unconscious visual processing: According to this model, unconscious visual processing is automatic in the sense that it is initiated without deliberate intention. However, unconscious visual processing is susceptible to attentional top-down control and is only elicited if the cognitive system is configured accordingly. In this article, we describe our attentional sensitization model and review recent evidence demonstrating attentional influences on subliminal priming, a prototypical example of an automatic process. We show that subliminal priming (a) depends on attentional resources, (b) is susceptible to stimulus expectations, (c) is influenced by action intentions, and (d) is modulated by task sets. These data suggest that attention enhances or attenuates unconscious visual processes in congruency with attentional task representations similar to conscious perception. We argue that seemingly paradoxical, hitherto unexplained findings regarding the automaticity of the underlying processes in many cognitive domains can be easily accommodated by our attentional sensitization model. We conclude this review with a discussion of future research questions regar-ding the nature of attentional control of unconscious visual processing.     

The detrimental effects of a suggestion of sexism in an instruction situation

This research investigates the hypothesis that the mere suggestion of sexism can harm women’s experience of an instruction situation. Across three experiments, women exposed to the suggestion about the sexism of a male instructor reported a less positive experience, performed worse on a logic test, and rated the instructor as less competent than did women who were not exposed to the suggestion. The same harmful consequences did not befall men, even when they were potential targets of the alleged sexism. To interpret results, the authors emphasize the concept of social identity threat: the concern that one will be the target not only of stereotypes about inferiority, but also a more general hostility based on a salient social identity. Results suggest the need to expand conceptions of discrimination to include systemic forms of identity threat that can be sufficient to produce harm, even in situations where differential treatment is initially absent.     

The mirror effect in recognition memory

The mirror effect in recognition memory refers to the fact that, with several different classes of stimuli, performance on new items from each class mirrors (is correlated with) performance on the corresponding classes of old items. Classes of stimuli that are accurately recognized as old when old are also accurately recognized as new when new; those that are poorly recognized as old when old are also poorly recognized as new when new. The statement above is shown not to be a tautology. A survey demonstrates that the effect holds for several types of variables (ways to classify stimuli)—word frequency, concreteness, meaningfulness, and others. The survey includes a total of 80 findings. The theoretical implications of the effect are considered.     

Body image in bulimic,dieting, and normal females

The present investigation examined body-size estimation and overvaluation of a thin shape in bulimic females, females having been obese as adults who later lost weight, females with no history of obesity who were dieting, and females with no history of obesity as adults and not currently dieting. Each subject was presented with a set of seven silhouettes, one having been drawn from the subject's actual photograph and the remaining silhouettes representing 2.5, 5, and 7.5% increases and decreases in the size of certain body areas of the original figure. Subjects selected both their actual size and their ideal size. In addition, objective raters selected an ideal size for each subject. The hypotheses that bulimics would overestimate their size or overvalue an ultrathin body size as compared with other females were not supported. A history of childhood obesity appears to influence significantly body-size overestimation. Finally, the hypothesis that bulimics would appear more dissatisfied with their body image was not supported, with the three groups currently dieting appearing equally dissatisfied with their shape.The authors greatly appreciate the assistance of the graphic artist, Susan Meier.     

A multicomponent investigation of the interaction of generalized anxiety and phobia

Forty female undergraduates forming four groups, high or low trait anxiety with or without a specific fear (rats), participated in a psychophysiological assessment of their response to the phobic object, a neutral object (rabbit), and to a general anxiety-induction procedure (threat of shock). Subjects also completed a number of tasks requiring sustained attention. Blood samples were drawn to determine thyroid hormone (T3 and T4) levels. Trait anxiety was found to interact with specific fear in response to the feared object. The high-trait anxious/high-fear group was most physiologically responsive to the rat. Trait- anxious subjects were more responsive to the threat of shock and showed performance deficits on reaction time, vigilance, and backward digit span tasks. These subjects also had significantly higher T3 and T4 levels. The findings are discussed with regard to the role of general anxiety in the etiology and/or maintenance of specific fears and the role of thyroid hormones in accentuating physiological response to feared stimuli.
