Retention of Quiet Eye in Older Skilled Basketball Players

There is mounting research to suggest that cognitive and motor expertise is more resistant to age-related decline than more general capacities. The authors investigated the retention of skills in medium-aged skilled (n = 14) and older-aged skilled (n = 7) athletes by comparing them with medium-aged less skilled (n = 15) and older-aged less skilled (n = 15) participants. Participants performed basketball free throws and dart throws as a transfer task under standardized conditions. Motor performance (accuracy) and perceptual performance (quiet eye) were examined across the four groups. There were significant differences between skill groups and age groups in throwing accuracy on both throwing tasks. Skilled players outperformed less skilled and medium-aged players outperformed older-aged players in basketball and dart throws. There were no significant differences in quiet eye duration across the skill or age groups in either task. These results indicate expertise in a perceptual motor task such as the basketball free throw can be retained in older athletes and that present models of skill maintenance should be re-evaluated to consider the issue of transfer.

Background

The diagnostic and statistical manual of mental disorders 5 (DSM-5) includes a revision of the DSM-IV criteria for somatoform disorders. The aim of the current work was to investigate whether (a) patients with DSM-IV diagnoses of somatization disorder, pain disorder and hypochondriasis and (b) whether patients categorized as having the DSM-5 somatic symptom disorder and illness anxiety disorder differ with respect to illness anxiety and cognition regarding somatic symptoms.

Material and methods

The data from 269 inpatients from the psychosomatic clinic Schön Klinik Bad Bramstedt were used. Somatoform disorders were diagnosed using the German version of the structured clinical interview for DSM-IV (SCID).

Results

Patients with a DSM-IV diagnosis of hypochondriasis differed in illness anxiety and catastrophizing interpretation of somatic symptoms compared to patients with other somatoform disorders. Patients with illness anxiety disorder differed in the catastrophizing interpretation of physical symptoms, autonomic sensations, bodily weakness and intolerance of physical complaints compared to patients with somatic symptom disorder.

Conclusion

The present results indicate that illness anxiety and a catastrophizing interpretation of somatic symptoms play a fundamental role in patients with somatoform disorders. Therefore, psychotherapy should address illness anxiety and health-related concerns in all patients with somatoform disorders.     

The consumer psychology of customer–brand relationships: Extending the AA Relationship model

The Attachment–Aversion (AA) Relationship model offers a unifying model of customer–brand relationships. To develop it further as a relevant consumer-psychology model, future research should examine three key factors: how brand perception differs from person perceptions; what role brand experiences play as determinants of customer–brand relationships, and how the AA Relationship model fits with other brand frameworks. The author offers insights and suggestions on how to address these three tasks.     

Differences in sharing knowledge interpersonally and via databases: The role of evaluation apprehension and perceived benefits

Knowledge sharing is an essential component of effective knowledge management. However, evaluation apprehension, or the fear that your work may be critiqued, can inhibit knowledge sharing. Using the general framework of social exchange theory, we examined the effects of evaluation apprehension and perceived benefit of knowledge sharing (such as enhanced reputation) on employees' knowledge sharing intentions in two contexts: interpersonal (i.e., by direct contact between two employees) and database (i.e., via repositories). Evaluation apprehension was negatively associated with knowledge sharing intentions in both contexts while perceived benefit was only positively associated with knowledge sharing intentions in the database context. Moreover, compared to the interpersonal context, evaluation apprehension was higher and knowledge sharing lower in the database context. Finally, the negative effects of evaluation apprehension upon knowledge sharing intentions were worse when perceived benefits were low compared to when perceived benefits were high.     

Dangerous Enough: Moderating Racial Bias with Contextual Threat Cues

Research shows that participants shoot armed Blacks more frequently and quickly than armed Whites, but make don't-shoot responses more frequently and quickly for unarmed Whites than unarmed Blacks. We argue that this bias reflects the perception of threat — specifically, threat associated with Black males. Other danger cues (not just race) may create a similar predisposition to shoot, and if these cues promote shooting when the target is White, they should attenuate racial bias. We embedded targets in threatening and safe backgrounds. Racial bias was evident in safe contexts but disappeared when context signaled danger, and this reduction was largely due to an increased tendency to shoot White targets.     

Ecstasy Use,Outcome Expectancies,and Sexual Risk Taking

Ecstasy has become one of the most widely used illicit drugs in Australia. This study investigated outcome expectancies as possible motivating and maintaining factors in ecstasy use and sexual risk‐taking behaviour. A sample of regular ecstasy users (N = 220) from Sydney and Canberra, Australia, was recruited for structured face‐to‐face interviews. They also completed an Ecstasy Expectancy Questionnaire. Seven of eight subscales significantly differentiated regular users from non‐users. Interestingly, light and heavier users held similar outcome expectancies, except that light users endorsed items on the sexual enhancement subscale more strongly than heavier users. Further investigation showed that the level of sexual risk taking observed in this sample was high, with the majority of participants reporting multiple partners, “casual” sexual encounters, sex under the influence of substances, and inconsistent condom use. Using logistic regression analyses, a key finding was that positive sex‐related ecstasy outcome expectancies were associated with involvement in disinhibited sexual behaviour under the influence of ecstasy. These effects persisted after statistically controlling for the frequency of ecstasy use. The findings suggest that sexual risk taking is related not only to the disinhibiting properties of ecstasy but also to beliefs that users hold about the effects of the drug.     

Designing Selection Systems for Medicine: The importance of balancing predictive and political validity in high‐stakes selection contexts

Selection into medical education and training is a high‐stakes process. A key unanswered issue is the effectiveness of measuring noncognitive predictors via both low‐fidelity and high‐fidelity selection approaches in this high‐stakes context. We review studies investigating the effectiveness of multiple selection instruments in terms of predictive validity, incremental validity, and applicant reactions in both entry‐level and advanced‐level medical selection. Our results show that the situational judgment test (SJT) is the best single predictor of performance, operationalized in multiple ways. In addition, the low‐fidelity SJT has incremental predictive power over cognitively oriented tests, and high‐fidelity assessment center (AC) exercises add incremental validity over the low‐fidelity (and less costly) selection methods. Concerning applicant reactions, results show that overall, the selection system is positively received. However, the method with the highest predictive validity – the SJT – received comparatively lower face validity ratings which may present a ‘justice dilemma’ for employers. Furthermore, various other stakeholders have a political interest in the selection methods used (e.g., government, the regulators and trade unions).     

The consumer psychology of brands

This article presents a consumer-psychology model of brands that integrates empirical studies and individual constructs (such as brand categorization, brand affect, brand personality, brand symbolism and brand attachment, among others) into a comprehensive framework. The model distinguishes three levels of consumer engagement (object-centered, self-centered and social) and five processes (identifying, experiencing, integrating, signifying and connecting). Pertinent psychological constructs and empirical findings are presented for the constructs within each process. The article concludes with research ideas to test the model using both standard and consumer-neuroscience methods.     

Brands on the brain: Do consumers use declarative information or experienced emotions to evaluate brands?

An fMRI study was conducted with unfamiliar and familiar (strong and weak) brands to assess linguistic encoding and retrieval processes, and the use of declarative and experiential information, in brand evaluations. As expected, activations in brain areas associated with linguistic encoding were higher for unfamiliar brands, but activations in brain areas associated with information retrieval were higher for strong brands. Interestingly, weak brands were engaged simultaneously in both processes. Most importantly, activations of the pallidum, associated with positive emotions, for strong brands and activations of the insula, associated with negative emotions, for weak and unfamiliar brands suggested that consumers use experienced emotions rather than declarative information to evaluate brands. As a result, brand experiences should be considered a key driver of brand equity in addition to brand awareness and cognitive associations.     

On models with variable universe

In this paper some parts of the model theory for logics based on generalised Kripke semantics are developed. Löwenheim-Skolem theorems and some applications of ultraproduct constructions for generalised Kripke models with variable universe are investigated using similar theorems of the model theory for classical logic. The results are generalizations of the theorems of [4].
