Discrimination of facial appearance stimuli in body dysmorphic disorder

Cognitive-behavioral models of body dysmorphic disorder (BDD) propose that information-processing biases--in particular, selective attention to a defect in one's appearance as well as improved aesthetical perception--might contribute to the development or maintenance of the disorder. In the present study, the authors tested the hypothesis that patients with BDD discriminate facial appearance stimuli more accurately than controls. Sixty female patients from a dermatological clinic participated in the study: 21 patients with BDD, 19 patients with disfiguring dermatological conditions, and 20 patients with nondisfiguring dermatological disorders. Participants rated dissimilarities between pictures of neutral faces that had been manipulated with regard to aesthetic characteristics. Manipulation ratings of participants with BDD were significantly more accurate than those of both control groups. Implications of these results for cognitive theories of BDD are discussed.     

Novelty and saliency in attentional capture by unannounced motion singletons

The present study examined attentional capture by an unannounced motion singleton in a visual search task. The results showed that a motion singleton only captured attention on its first unannounced occurrence when the observers had not encountered moving items before in the experiment, whereas it failed to capture when observers were familiar with moving items. This indicates that motion can capture attention independently of top-down attentional control settings, but only when motion as a feature is unexpected and new. An additional experiment tested whether salient items can capture attention when all stimuli possess new and unexpected features, and novelty information cannot guide attention. The results showed that attention was shifted to the location of the salient item when all items were new and unexpected, reinforcing the view that salient items receive attentional priority. The implications of these results for current theories of attention are discussed.     

The Interpersonal Adaptiveness of Dispositional Guilt and Shame: A Meta‐Analytic Investigation

Despite decades of empirical research, conclusions regarding the adaptiveness of dispositional guilt and shame are mixed. We use meta‐analysis to summarize the empirical literature and clarify these ambiguities. Specifically, we evaluate how guilt and shame are uniquely related to pro‐social orientation and, in doing so, highlight the substantial yet under‐acknowledged impact of researchers’ methodological choices. A series of meta‐analyses was conducted investigating the relationship between dispositional guilt (or shame) and pro‐social orientation. Two main methodological moderators of interest were tested: test format (scenario vs. checklist) and statistical analysis (semi‐partial vs. zero‐order correlations). Among studies employing zero‐order correlations, dispositional guilt was positively correlated with pro‐social orientation (k = 63, Mr = .13, p < .001), whereas dispositional shame was negatively correlated, (k = 47, Mr = –.05, p = .07). Test format was a significant moderator for guilt studies only, with scenario measures producing significantly stronger effects. Semi‐partial correlations resulted in significantly stronger effects among guilt and shame studies. Although dispositional guilt and shame are differentially related to pro‐social orientation, such relationships depend largely on the methodological choices of the researcher, particularly in the case of guilt. Implications for the study of these traits are discussed.     

Heart Rate Recovery After Exercise in Outpatients with Coronary Heart Disease: Role of Depressive Symptoms and Positive Affect

Heart rate recovery after 1 min of exercise cessation (HRR-1) is an important prognostic factor in patients with cardiovascular disease (CVD). We aimed to further elucidate the association between HRR-1 and known psychosocial risk factors in patients referred for comprehensive cardiac rehabilitation. We examined 521 patients with coronary heart disease in the first week of an outpatient cardiac rehabilitation program. Depressive and anxiety symptoms were measured with the Hospital Anxiety and Depression Scale, and positive (PA) and negative affect were rated with the Global Mood Scale. Depressive symptoms showed a significant inverse relationship with HRR-1 (p?<?.05), controlling for sociodemographic and medical covariates, whereas anxiety symptoms did not show a significant association. PA made a significant contribution to HRR-1 as well (p?<?.05). Our findings suggest an independent association between HRR-1 and psychosocial risk factors of CVD.     

Explain this: explaining childhood events inflates confidence for those events

To examine whether explaining hypothetical childhood events makes people more confident that the events really happened, we used a method similar to the imagination inflation procedure devised by Garry, Manning, Loftus, and Sherman (1996). First, participants rated how confident they were that a list of events occurred in their childhood. Two weeks later, participants explained how four of the eight target events could have happened to them before the age of 10. Finally, participants made confidence ratings about the list of childhood events for a second time. Participants were more confident that the explained hypothetical childhood events really did happen compared to events they did not explain. We discuss both theoretical and practical implications of these results. Copyright © 2004 John Wiley & Sons, Ltd.     

Adaptation to biological motion leads to a motion and a form aftereffect

Recent models have proposed a two-stage process of biological motion recognition. First, template or snapshot neurons estimate the body form. Then, motion is estimated from body form change. This predicts separate aftereffects for body form and body motion. We tested this prediction. Observers viewing leftward- or rightward-facing point-light walkers that walked forward or backward subsequently experienced oppositely directed aftereffects in stimuli ambiguous in the facing or the walking direction. These aftereffects did not originate from adaptation to the motion of the individual light points, because they occurred for limited-lifetime stimuli that restrict local motion. They also occurred when the adaptor displayed a random sequence of body postures that did not induce the walking motion percept. We thus conclude that biological motion gives rise to separate form and motion aftereffects and that body form representations are involved in biological motion perception.     

When history constrains identity: Expressing the self to others against the backdrop of a problematic past

Negative histories threaten collective identity. Much research has focussed on how group members strategically defend against such threats. However, within certain groups such defence is difficult—because the group's past actions were unambiguously negative and because these were public and continue to frame relations with outgroups. We explored the consequences of this form of identity constraint on the individual's experience of the self. Two studies varied the salience of the past as German participants expressed their national identity to either an ingroup (German) or outgroup (English) audience. In both studies expressing German identity to an outgroup audience when the past was salient resulted in a more fragmented sense of self and reduced self‐esteem. This effect was mediated through a perceived inability to enact the self. Results are discussed with respect to the power of context to constrain identity expression, and the consequences of this for the self. Copyright © 2010 John Wiley & Sons, Ltd.     

Reversing the hands of time: changing the mapping from seeing to saying

To describe a scene, speakers must map visual information to a linguistic plan. Eye movements capture features of this linkage in a tendency for speakers to fixate referents just before they are mentioned. The current experiment examined whether and how this pattern changes when speakers create atypical mappings. Eye movements were monitored as participants told the time from analog clocks. Half of the participants did this in the usual manner. For the other participants, the denotations of the clock hands were reversed, making the big hand the hour and the little hand the minute. Eye movements revealed that it was not the visual features or configuration of the hands that determined gaze patterns, but rather top-down control from upcoming referring expressions. Differences in eye-voice spans further suggested a process in which scene elements are relationally structured before a linguistic plan is executed. This provides evidence for structural rather than lexical incrementality in planning and supports a "seeing-for-saying" hypothesis in which the visual system is harnessed to the linguistic demands of an upcoming utterance.
