Changes in step variability of new walkers with typical development and with Down syndrome

Models of human gait are based on adult locomotion. C. E. Bauby and A. D. Kuo (2000) proposed that adults rely on passive mechanisms at the spinal level to control motion in the anteroposterior direction and rely on direct monitoring of postural control in the lateral direction. The authors' purpose in this study was to determine if that model applies to control at the onset of walking in typically developing toddlers (n = 9) and in toddlers with Down syndrome (n = 6). Their longitudinal data suggested that toddlers control gait in a distinctly different manner than adults do. An adult pattern of control emerges with experience. In addition, the effect of experience on the emergence of that pattern is magnified by task-specific early intervention. The present data support the emergence and discovery of efficient patterns of control in this fundamental human behavior.     

What is the relationship between synaesthesia and visuo-spatial number forms?

This study compares the tendency for numerals to elicit spontaneous perceptions of colour or taste (synaesthesia) with the tendency to visualise numbers as occupying particular visuo-spatial configurations (number forms). The prevalence of number forms was found to be significantly higher in synaesthetes experiencing colour compared both to synaesthetes experiencing taste and to control participants lacking any synaesthetic experience. This suggests that the presence of synaesthetic colour sensations enhances the tendency to explicitly represent numbers in a visuo-spatial format although the two symptoms may nevertheless be logically independent (i.e. it is possible to have number forms without colour, and coloured numbers without forms). Number forms are equally common in men and women, unlike previous reports of synaesthesia that have suggested a strong female bias. Individuals who possess a number form are also likely to possess visuo-spatial forms for other ordinal sequences (e.g. days, months, letters) which suggests that it is the ordinal nature of numbers rather than numerical quantity that gives rise to this particular mode of representation. Finally, we also describe some consequences of number forms for performance in a number comparison task.     

Social anxiety and problematic alcohol consumption: the mediating role of drinking motives and situations

Social anxiety is inconsistently associated with alcohol use variables. To elucidate factors that contribute to the relationship between social anxiety and problematic alcohol use, the present study investigated drinking motives and drinking situations in an undergraduate sample (N = 293). Social anxiety was significantly correlated with endorsement of enhancement drinking motives (i.e., drinking to enhance positive experiences or emotions) but not social or coping motives. Social anxiety was also correlated with endorsement of drinking in the following high-risk situations: unpleasant emotions, conflict with others, social pressure, and testing personal control. Importantly, enhancement motives and each of these drinking situations mediated the relationship between social anxiety and alcohol-related problems. Findings suggest that alcohol use to enhance positive affect or in response to these specific situations may account for the risk for alcohol-related problems among those with social anxiety.     

“Man's best friend:” How the presence of a dog reduces mental distress after social exclusion

A substantial amount of research shows that social exclusion is a threat to mental health. In the research reported here, we tested the hypothesis that the presence of a companion animal can serve as a buffer against these adverse effects. In a controlled laboratory experiment, we found that only socially excluded participants who did not work in the presence of a dog reported lower mental well-being compared with socially excluded participants who performed in the presence of a dog and participants who were not socially excluded. The theoretical and practical implications of these findings are discussed.     

Cognitive style and learning: performance of adaptors and innovators in a novel dynamic task

The influence of cognitive style on performance in a novel dynamic task modelled on the task of controlling air traffic was investigated. It was hypothesized that participants who preferred a more adaptive cognitive style would maintain better rule adherence and safe distances between aircraft in a low‐fidelity air traffic control task than those who preferred a more innovative style. Problems were presented to participants using computer‐based scenarios in screening, practice, and experimental trials. Performance was measured by the number of times the participant violated two types of scenario rules. Screening, practice, and experimental performance were analysed separately. Cognitive style had a significant effect on performance only during experimental trials. Performance of individuals who preferred a more adaptive style improved across experimental trials while those preferring a more innovative style did not. Results suggest that the more innovative participants, although perhaps having some initial advantage, may not be able to sustain performance in this type of task.

Balancing Confidentiality and Collaboration Within Multidisciplinary Health Care Teams

As multidisciplinary perspectives are increasingly integrated into the treatment of health problems, opportunities for clinical psychologists in medical settings are expanding. Although cross-discipline collaboration is at the core of multidisciplinary treatment models, psychologists must be particularly cautious about information sharing due to their profession??s ethical standards regarding patient confidentiality. Psychologists?? ethical obligations require them to achieve a delicate balance between contributing to the treatment team and protecting patient confidentiality. In the current review, relevant ethical standards and federal guidelines are applied to everyday practices of clinical psychologists in medical settings. Additionally, recommendations for individual psychologists, health care organizations, and graduate training programs are presented.     

Fit of Political Skill to the Work Context: A Two‐Study Investigation

A two‐study investigation was designed to examine the role of job type (i.e. fit of political skill to work context) as a contextual moderator of the political skill–job performance relationship. Specifically, it was hypothesised that political skill operates most effectively in enterprising job contexts, and thus is most predictive of job performance in such contexts, but political skill would demonstrate no relationship with job performance in job contexts that did not emphasise interpersonal interaction and effectiveness. In Study 1, enterprising job demands interacted with political skill to affect job performance. That is, political skill positively and significantly predicted job performance in enterprising job contexts, as hypothesised. Study 2 selected one specific job context (i.e. insurance sales) high in enterprising job demands, and hypothesised that political skill would significantly predict objective measures of insurance sales (i.e. sales volume, performance‐based income, performance‐based commission rate, and performance‐based status). The results demonstrated significant predictive effects of political skill (i.e. beyond age, sex, education level, tenure on the job, and experience in sales) on all four measures of sales performance. Contributions and implications of this research, strengths and limitations, and directions for future study are discussed.
