Influence of feedback modality on sensorimotor adaptation: contribution of visual, kinesthetic, and verbal cues

In 4 studies, the authors tested the contributions of visual, kinesthetic, and verbal knowledge of results to the adaptive control of reaching movements toward visual targets. The same apparatus was used in all experiments, but the procedures differed in the sensory modality of the feedback that participants (N s = 5, 5, 6, and 6, respectively, in Experiments 1, 2, 3, and 4) received about their performances. Using biased visual, proprioceptive, or verbal feedback, the authors introduced a 5 degrees shift in the visuomanual relationship. Results showed no significant difference in the final amount of adaptation to the mismatch: On average, participants adapted to 79% of the perturbation. That finding is consistent with the view that adaptation is a multisensory, highly flexible process whose efficiency does not depend on the sensory channel conveying the error signal.     

Influence of ball type on home advantage in French professional soccer

The home advantage has been consistently found in soccer matches, but conclusive evidence of the origin of this home advantage has yet to be identified. One factor often thought to contribute is familiarity with a local facility. The present study examined home advantage in the French professional soccer male championships (20 teams in each Ligue 1 and 2) and explored the influence of soccer ball type on this phenomenon. Whether it is knowing how a soccer ball rolls on a particular grass surface or some other aspect, the home team can react to the situation better if they know from experience what is likely to happen. The results suggest that type of soccer ball may have an influence on home advantage. Confounding factors are discussed.     

Can medicalization be good? Situating medicalization within bioethics

Medicalization has been a process articulated primarily by social scientists, historians, and cultural critics. Comparatively little is written about the role of bioethics in appraising medicalization as a social process. The authors consider what medicalization means, its definition, functions, and criteria for assessment. A series of brief case sketches illustrate how bioethics can contribute to the analysis and public policy discussion of medicalization.

Listen Out! Behavioural and Subjective Responses to Verbal Warnings

Both the behavioural and subjective impacts of single‐word spoken warnings were examined. Behaviourally, the effect of infrequently occurring warnings was studied through their disruptive impact on a visually presented serial recall task. In separate experiments, ratings of the same words were elicited. Experiment 1 showed a localized effect of the warnings (on the item immediately following the warning), with the urgently intoned warning having a greater disruptive effect than its valence (emotional content). Valence and intonation (urgency) did not interact. The performance changes were mirrored in the ratings of the words. Experiment 2 showed no systematic effect on performance of either the action‐relatedness of the word or its lexicality. There was, however, a systematic effect of lexicality but not action‐relatedness on ratings. The study demonstrates the feasibility of using objective performance methods to establish the likely effects of verbal warnings and the utility of using such methods for the design of alarm systems.

Family Background and Individual Measures as Predictors of Turkish Primary School Children's Academic Achievement

The primary purpose of this study was to predict academic grade point averages (GPAs) of Turki primary school children, using family background and individual measures (sociometric standing, self-reported loneliness, and social efficacy) as predictors. We hypothesized that these two measures would explain the wide variation in GPA for samples differing with respect to sex and paternal education. Regression analyses with male and female subsamples revealed that the background measures explained twice as much variance in GPA, popularity, and loneliness for girls as for boys. Another finding was that the background measures explained a greater proportion of the variance in GPA for children with less-versus more-educated fathers, whereas individual measures explained a greater proportion of the variance for children with more as opposed to less educated fathers.     

Longitudinal links between childhood peer acceptance and the neural correlates of sharing

Childhood peer acceptance is associated with high levels of prosocial behavior and advanced perspective taking skills. Yet, the neurobiological mechanisms underlying these associations have not been studied. This functional magnetic resonance imaging study examined the neural correlates of sharing decisions in a group of adolescents who had a stable accepted status (n = 27) and a group who had a chronic rejected status (n = 19) across six elementary school grades. Both groups of adolescents played three allocation games in which they could share money with strangers with varying costs and profits to them and the other person. Stably accepted adolescents were more likely to share their money with unknown others than chronically rejected adolescents when sharing was not costly. Neuroimaging analyses showed that stably accepted adolescents, compared to chronically rejected adolescents, exhibited higher levels of activation in the temporo‐parietal junction, posterior superior temporal sulcus, temporal pole, pre‐supplementary motor area, and anterior insula during costly sharing decisions. These findings demonstrate that stable peer acceptance across childhood is associated with heightened activity in brain regions previously linked to perspective taking and the detection of social norm violations during adolescence, and thereby provide insight into processes underlying the widely established links between peer acceptance and prosocial behavior.     

Visual distraction and visuo‐spatial memory: A sandwich effect

The functional characteristics of visuo‐spatial serial memory and its sensitivity to irrelevant visual information are examined in the present study, through the investigation of the sandwich effect (e.g., ). The memory task was one of serial recall for the position of a sequence of seven spatially and temporally separated dots. The presence of irrelevant dots interpolated with to‐be‐remembered dots affected performance over most serial positions (Experiment 1) but that effect was significantly reduced when the interpolated dots were distinct from the to‐be‐remembered dots by colour and shape (Experiment 2). Parallels are made between verbal and spatial serial memory, and the reduction of the sandwich effect is discussed in terms of the contribution of perceptual organisation and attentional factors in short‐term memory.
