Reciprocal influences of attentional focus on postural and suprapostural task performance

The authors examined the influence that attentional focus on either a postural or a suprapostural task had on the performance of each task. Participants (N = 32) stood on an inflated rubber disk and held a pole horizontally. All participants performed under 4 attentional focus conditions: external (disk) or internal (feet) focus on the postural task, and external (pole) or internal (hands) focus on the suprapostural task. Compared with internal focuses, external focuses on either task resulted in similar and reduced postural sway. Response frequency on each task increased when participants focused on the respective task. Finally, an external focus on either task produced higher frequencies of responding on the suprapostural task. The authors conclude that suprapostural task goals have a stronger influence on postural control than vice versa, reflecting the propensity of the motor system to optimize control processes on the basis of the desired movement effect.     

Healthy and unhealthy emotion regulation: personality processes, individual differences, and life span development

Abstract Individuals regulate their emotions in a wide variety of ways. Are some forms of emotion regulation healthier than others? We focus on two commonly used emotion regulation strategies: reappraisal (changing the way one thinks about a potentially emotion‐eliciting event) and suppression (changing the way one responds behaviorally to an emotion‐eliciting event). In the first section, we review experimental findings showing that reappraisal has a healthier profile of short‐term affective, cognitive, and social consequences than suppression. In the second section, we review individual‐difference findings, which show that using reappraisal to regulate emotions is associated with healthier patterns of affect, social functioning, and well‐being than is using suppression. In the third section, we consider issues in the development of reappraisal and suppression and provide new evidence for a normative shift toward an increasingly healthy emotion regulation profile during adulthood (i.e., increases in the use of reappraisal and decreases in the use of suppression).     

The effects of cooperation and competition on intrinsic motivation and performance

The authors examined the effects of competition and cooperation on intrinsic motivation and performance in 4 studies. Across 3 behavioral studies that involved shooting a basketball, no differences were observed between competition and cooperation on task enjoyment or performance. However, the combination of competition and cooperation (intergroup competition) consistently led to higher levels of intrinsic motivation, and in 2 of the 3 studies, performance. In a questionnaire study, the authors replicated the positive effects of intergroup competition on enjoyment and examined process measures that might account for these effects. These findings suggest that competition and cooperation both have positive aspects and that structuring recreational activities to include both can facilitate high levels of both intrinsic motivation and performance.     

The effects of motor neurone disease on language: further evidence

It might sound surprising that Motor Neurone Disease (MND), regarded still by many as the very example of a neurodegenerative disease affecting selectively the motor system and sparing the sensory functions as well as cognition, can have a significant influence on language. In this article we hope to demonstrate that language dysfunction is not only a pronounced and well documented symptom in some MND patients but also that the study of language in MND can address interesting theoretical questions about the representation of language and conceptual knowledge in the brain. After a brief introduction delineating clinical and pathological features of the disease we discuss the evidence available in the literature for language dysfunction in MND. We then present linguistic data from our own study of seven patients with MND/dementia/aphasia syndrome focusing on the dissociation between noun and verb processing. To illustrate the clinical, neuropsychological and linguistic aspects of MND we describe in more detail the patient E.N., a pathologically confirmed case of MND/dementia. Finally, we attempt to characterise the nature of the linguistic impairment in MND in the light of current debates about the mechanisms underlying noun/verb dissociation.     

Size of the neocerebellar vermis is associated with cognition in healthy elderly men

Cerebellar volumes show small positive correlations with cognitive ability in young adults, but no studies have examined this relationship in older adults. Furthermore, no studies have examined relationships between sizes of subareas of the cerebellum and cognitive ability. We hypothesized that size of the two areas of the neocerebellar vermis would correlate with a battery of eight cognitive tests in 50 men aged 65-70. Size of the neocerebellar areas of the vermis correlated positively with several cognitive tests (r's=.29-.37, p<.05), whilst sizes of other parts of the vermis did not correlate with any cognitive tests. Total cerebellar volumes correlated significantly with a test of nonverbal reasoning (r=.030, p=.42). These findings suggest a specific association of neocerebellar vermis size with variations in cognitive ability in older adults.     

A Web-based family problem-solving intervention for families of children with traumatic brain injury

We developed a Web-based intervention for pediatric traumatic brain injury (TBI) and examined its feasibility for participants with limited computer experience. Six families, including parents, siblings, and children with TBI, were given computers, Web cameras, and high-speed Internet access. Weekly videoconferences with the therapist were conducted after participants completed on-line interactive experiences on problem solving, communication, and TBI-specific behavior management. Families were assigned to videoconference with NetMeeting (iBOT cameras) or ViaVideo. Participants ranked the Web site and videoconferences as moderately to very easy to use. ViaVideo participants rated videoconferencing significantly more favorably relative to face-to-face meetings than did NetMeeting participants. Both the Web site and videoconferencing were rated as very helpful. All families demonstrated improved outcomes on one or more target behaviors, including increased understanding of the injury and improved parent-child relationships. All parents and siblings and all but 1 child with TBI said they would recommend the program to others. We conclude that a face-to-face intervention can be successfully adapted to the Web for families with varied computer experience.     

The Temporal Automated System for Taste Experiments (TASTE)

We describe a new, open flow device for presenting taste stimuli to human subjects under controlled conditions of timing. The device delivers each stimulus as a mist to the participant’s tongue through one of 16 nozzles attached to a linear slide. Software controls the position of the slide, the duration of the stimulus, and the duration of the pre- and poststimulus water rinses and records the responses of the participant. Temporal characteristics of this system make it especially applicable to studies on the role of attention in taste perception.     

Body dissatisfaction in married women: the role of spousal influence and marital communication patterns

Family factors and the media have been established as determinants of body satisfaction, yet little research has looked at the contribution of spousal influence in body dissatisfaction. Marital quality and satisfaction can be a protective factor in the health of women, while high rates of criticism have been associated with poorer health outcomes. The present study investigated the relationship between perceptions of family and spousal factors and body dissatisfaction in married women. Additionally, the impact of marital communication was investigated. Seventy-seven married women completed self-report questionnaires assessing familial body-focused comments, spousal evaluation of a wife’s body, marital communication patterns, and body dissatisfaction. After controlling for weight status, women’s perceptions of familial body-focused comments and spousal evaluation emerged as significant predictors of body dissatisfaction. It was also found that more destructive communication patterns moderated the effect of perceived spousal evaluation on body dissatisfaction. This study provides some context for understanding the impact of specific influences on women’s body dissatisfaction.
