Body image importance and body dissatisfaction among indigenous Australian adolescents

Despite their elevated risk of health problems and a propensity to be more overweight or underweight relative to the other members of the Australian population, there has been no previous investigation of body image concerns among Indigenous Australians. In this study we investigated the level of body image importance and body image dissatisfaction among 19 rural Indigenous adolescents (7 males, 12 females) and 28 urban Indigenous adolescents (15 males and 13 females). Our hypotheses that there would be gender differences in body image importance and body image satisfaction were not generally supported. However, males placed more importance on muscle size and strength than females, and rural participants placed more importance on weight than urban participants. Comparison to existing data obtained from Caucasian adolescents suggested that Indigenous youth may be less concerned and dissatisfied with body weight and shape. These results are discussed in relation to findings from studies of non-Indigenous adolescents, and Indigenous health issues. The limitations of the current study and the need for further studies are also discussed.     

General and specific traits of personality and their relation to sleep and academic performance

Few studies have examined the links between personality variables and sleep and their combined effect on specific real-world outcomes. Participants in this study completed numerous personality, sleep, and performance measures; we examined the associations among these measures. Personality was assessed using the Five-Factor Model. The personality trait of Conscientiousness (especially its facet of Achievement Striving) was a substantial predictor of academic performance. Analyses of the sleep variables revealed three distinct constructs: quantity, quality, and schedule. Sleep quantity showed few interesting correlates. In contrast, sleep quality was associated with greater well-being and improved psychological functioning, whereas sleep schedule (i.e., average rising and retiring times) was significantly related to Conscientiousness, such that conscientious individuals maintain earlier schedules.     

Does a prosocial-selfish distinction help explain the biological affects? Comment on Buck (1999)

R. Buck (1999) argued that a conceptual distinction between prosocial and selfish motivation is necessary to understand the biological affects (consciously experienced feelings and desires having an innate neurochemical basis). However, at a biological level of analysis, a prosocial-selfish distinction is doubtful empirically and conceptually. For this reason, Buck's proposed typology of biological affects is unclear. Moreover, a prosocial-selfish distinction is not necessary to explain hemispheric differences in brain activity associated with affect. In contrast, an approach-withdrawal distinction explains some data uniquely well, although numerous exceptions imply that simple models are inadequate. To extend hemispheric models of experienced emotion, a prosocial-selfish distinction is unlikely to be explanatory, whereas an alternative account based on a distinction between verbal and nonverbal working memory may be useful.     

Dyslexia linked to talent: global visual-spatial ability

Dyslexia has long been defined by deficit. Nevertheless, the view that visual-spatial talents accompany dyslexia has grown, due to reports of individuals with dyslexia who possess visual-spatial strengths, findings of elevated incidence of dyslexia in certain visual-spatial professions, and the hypothesis that left-hemisphere deficits accompany right-hemisphere strengths. Studies have reported superior, inferior, and average levels of visual-spatial abilities associated with dyslexia. In two investigations, we found an association between dyslexia and speed of recognition of impossible figures, a global visual-spatial task. This finding suggests that dyslexia is associated with a particular type of visual-spatial talent-enhanced ability to process visual-spatial information globally (holistically) rather than locally (part by part).     

Categorical perception of speech stimuli in children at risk for reading difficulty

Children determined to be at risk (n = 24) or not at risk (n = 13) for reading difficulty listened to tokens from a voice onset time (VOT) (/ga/-/ka/) or tone series played in a continuous unbroken rhythm. Changes between tokens occurred at random intervals and children were asked to press a button as soon as they detected a change. For the VOT series, at-risk children were less sensitive than not-at-risk children to changes between tokens that crossed the phonetic boundary. Maps of group stimulus space produced using multidimensional scaling of reaction times for the VOT series indicated that at-risk children may attend less to the phonological information available in the speech stimuli and more to subtle acoustic differences between phonetically similar stimuli than not-at-risk children. Better phonological processing was associated with greater sensitivity to changes between VOT tokens that crossed the phonetic boundary and greater relative weighting of the phonological compared to the acoustic dimension across both groups.     

Lapses of concentration and dyslexic performance on the Ternus task

Recently, Cestnick and Coltheart (Cognition 71 (1999) 231) have reported evidence of abnormal performance on the Ternus apparent motion task in dyslexics. We demonstrate that some aspects of their data may be accounted for by more frequent lapses of concentration in the dyslexic group than in controls. We then report on a study in which a modification of the Ternus procedure was employed to simplify the task and to control for the effects of inattention. The results suggest that dyslexics do genuinely differ from normal readers in their perceptual processing.     

If You Are Emotionally Intelligent: The effects of customer‐related social stressors on counterproductive work behavior for front‐line service employees

Recent literature in the area of employee–customer interactions suggests that stressful encounters contribute to negative outcomes for service employees. Few studies, however, have focused on the effects of customer‐related social stressors (CSS) on counterproductive work behavior (CWB) among front‐line service employees. The researchers tested a moderated mediation model of the effects of CSS on CWB with the key objective of exploring the mediation effects of emotional exhaustion and the moderating effects of emotional intelligence on this relationship. Based on a sample of 244 call center representatives in China, the research revealed that CSS led to emotional exhaustion, which, in turn, related to CWB for service employees. Furthermore, emotional intelligence acted as a buffer on the effects of CSS on CWB via emotional exhaustion.     

The MR2: A multi-racial,mega-resolution database of facial stimuli

Faces impart exhaustive information about their bearers, and are widely used as stimuli in psychological research. Yet many extant facial stimulus sets have substantially less detail than faces encountered in real life. In this paper, we describe a new database of facial stimuli, the Multi-Racial Mega-Resolution database (MR2). The MR2 includes 74 extremely high resolution images of European, African, and East Asian faces. This database provides a high-quality, diverse, naturalistic, and well-controlled facial image set for use in research. The MR2 is available under a Creative Commons license, and may be accessed online.     

Can Video Self-Modeling Improve Affected Limb Reach and Grasp Ability in Stroke Patients?

The authors examined whether feedforward video self-modeling (FF VSM) would improve control over the affected limb, movement self-confidence, movement self-consciousness, and well-being in 18 stroke survivors. Participants completed a cup transport task and 2 questionnaires related to psychological processes pre- and postintervention. Pretest video footage of the unaffected limb performing the task was edited to create a best-of or mirror-reversed training DVD, creating the illusion that patients were performing proficiently with the affected limb. The training yielded significant improvements for the forward movement of the affected limb compared to the unaffected limb. Significant improvements were also seen in movement self-confidence, movement self-consciousness, and well-being. FF VSM appears to be a viable way to improve motor ability in populations with movement disorders.
