An Ecological Framework for Evaluating Relationship‐Functional Aspects of Youth Mentoring1

The present research examined what is necessary to make youth mentoring effective. Central to the discussion is mentee–mentor relationship quality in relation to program effectiveness. Data were drawn from an ongoing youth mentoring program organized in Hong Kong using a conceptual framework derived from ecological psychology to guide analysis. Data analysis followed a multistage process. Quantitative factor analysis was computed to identify the principal components of the mentee–mentor relationship. Then, to explore subjective meanings of the quantitative findings, in‐depth interviews were conducted with 48 mentees who were randomly selected from the respondents. Further statistical associations and qualitative categorizations were conducted with this subsample to examine the complex relations between the relationship outcomes and the program (functional) outcomes.     

Voluntary timing and brain function: an information processing approach.

This article takes an information processing perspective to review current understanding of brain mechanisms of human voluntary timing. Theoretical accounts of timing of the production of isochronous tapping and rhythms and of bimanual responding repetitive responding are reviewed. The mapping of higher level temporal parameter setting and memory processes and of lower level motor implementation process onto cortical and subcortical brain structures is discussed in relation to evidence from selective lesions in a range of neurological motor disorders. Brain activation studies that have helped identify key brain structures involved in the control of timing are reviewed.     

Cognitive demands of error processing associated with preparation and execution of a motor skill

Maxwell et al. [Maxwell, J. P., Masters, R. S. W., Kerr, E., & Weedon, E. (2001). The implicit benefit of learning without errors. The Quarterly Journal of Experimental Psychology, 54A, 1049–1068. The implicit benefit of learning without errors. The Quarterly Journal of Experimental Psychology, 54A, 1049–1068] suggested that, following unsuccessful movements, the learner forms hypotheses about the probable causes of the error and the required movement adjustments necessary for its elimination. Hypothesis testing is an explicit process that places demands on cognitive resources. Demands on cognitive resources can be identified by measuring probe reaction times (PRT) and movement times. Lengthened PRT and movement times reflects increased cognitive demands. Thus, PRT and movement times should be longer following errors, relative to successful, movements. This hypothesis was tested using a motor skill (golf putting). Furthermore, the association between error processing and the preparation and execution phases of movement was examined. The data confirmed that cognitive demand is greater for trials following an error, relative to trials without an error. This effect was apparent throughout learning and in both the preparatory and execution phases of the movement. Cognitive effort also appeared to be higher during movement preparation, relative to movement execution.     

Women’s Perspectives Related to Occupational Performance Following Participation in Substance Use Recovery Programs

Very little research has examined how substance abuse programs affect occupational performance. The progression of addiction and its etiology for women are still under-reported. This study aimed to explore perceived effects of substance use and participation in peer-based programs on women’s occupational performance. Qualitative semi-structured interviews were completed with seven women. Four themes were identified: (1) substance use did not markedly inhibit participation in daily life; (2) recovery was supported by replacing substance related occupations with non-substance related occupations; (3) perceived value of shared perspectives and experiences with others; and (4) the embracing of new perspectives as part of recovery.     

Bilingual comparison of Mandarin and English cognitive bias tasks

Most research into cognitive biases has used Western samples, despite potential East-West socio-cultural differences. One reason is the lack of appropriate measures for non-Westerners. This study is about cross-linguistic equivalence which needs to be established before assessing cross-cultural differences in future research. We developed parallel Mandarin and English measures of interpretation bias and attention bias using back-translation and decentering procedures. We assessed task equivalence by administering both sets of measures to 47 bilingual Mandarin-English speakers. Interpretation bias measurement was similar and reliable across language versions, confirming suitability of the Mandarin versions for future cross-cultural research. By contrast, scores on attention bias tasks did not intercorrelate reliably, suggesting that nonverbal stimuli such as pictures or facial expressions of emotion might present better prospects for cross-cultural comparison. The development of the first set of equivalent measures of interpretation bias in an Eastern language paves the way for future research investigating East-West differences in biased cognition.     

Cognitive factors associated with depression and anxiety in adolescents: A two-year longitudinal study

Background/Objective: To examine the roles of anxiety sensitivity and attentional bias in the development of anxiety and depression symptoms among adolescents. Method: 214 grade 7 to grade 10 Hong Kong Chinese students completed a package of psychometric inventories to measure levels of anxiety sensitivity, selective attentional processing, and anxiety and depressive symptoms in 2016 and then again in 2017. Results: Girls, when compared with boys, exhibited more anxiety symptoms and anxiety sensitivity in 2016. They also reported a significant increase in mean depression level from 2016 to 2017. Regression analyses revealed that the physical-concerns dimension of anxiety sensitivity, positive attentional bias, and to a lesser extent negative attentional bias were related to the development of both anxiety and depression symptoms one year later. Fear of mental incapacity could predict depression one year later but not anxiety symptoms. Conclusions: Intervention through anxiety sensitivity training to reduce somatic concerns and attentional bias modification to increase habitual attention to positive stimuli and to disengage from negative stimuli can reduce anxiety and depression symptoms among high school students.     

Grasp size and accuracy of approach in reaching

In reaching for an object in the environment, it has been suggested that movement components concerned with transport of the hand toward the object and those related to grasping the object are organized and executed independently. An experiment is reported that demonstrates people adjust grasp aperture to compensate for factors affecting transport error. Grasp aperture was found to be greater in reaching movements performed faster than normal, and grasp aperture was also found to be wider when reaching with the eyes closed. In both cases, transport was spatially less accurate. It is argued that, in advance of movement, formation of grasp is planned to take into account not only the perceived characteristics of the object but, also, internalized information based on past experience about the likely accuracy of the transport component.     

The effect of family variables on child weight change

Previous research has shown that family size, the number of obese persons living at home, and parental weight influence the development of childhood obesity. Our study reports the relevance of these factors to child weight loss during a 1-year treatment period. Multiple linear regression procedures showed that the amount of relative weight change was related to initial treatment success, the number of children in the family, and the gender of the child. Children who were more successful lost more weight initially, had fewer siblings, and were female. These results suggest that family size may interact with treatment to determine weight change. The effects of family size on outcome may be operating simply by reducing the amount of time that a parent has to spend with the child in promoting behavior change. Likewise, increased family size may be operating as a stressor, reducing the effectiveness of parents in effectively managing their children.
