Assimilation Effects in Coincident Timing Responses

Abstract

The purpose of the study was to investigate ways in which gender-related perceptions and actions influenced students' construction of realities in curriculum-in-action in secondary school physical education. The participants were junior and senior secondary school students in a midwestern city in the United States. Data collection methods included observations and interviews. Data were analyzed with inductive analytical procedures. The findings of the study revealed that a majority of the female and male students reproduced traditionally dominant forms of femininity and masculinity. Female students patterned their behavior consistent with feminine ideology in selecting and participating in class activities, and male students chose and participated in class activities along masculine conceptions. The results were interpreted with reproduction and resistance theories. While femininity and masculinity cultures were reproduced through students' choice of activities and participation patterns, these cultures were resisted through students' construction of oppositional behavior.     

Effects of Proximity on the Choice to Be Physically Active or Sedentary

The link between physical activity and weight loss has precipitated interest in interventions to foster adherence to exercise. It has been suggested that treatment effects, when significant, should be analyzed to determine theory-based mediators. This research assessed possible mediation of changes in Physical Self-Concept, Exercise Self-Efficacy, Total Mood Disturbance, and Body Areas Satisfaction scores on the relationship between exercise session attendance and participation by obese women in a 6-month treatment based on tenets of social cognitive theory (n = 73) or a control condition (n = 64). Participation in the treatment was associated with significantly greater exercise session attendance and significantly greater improvements in Physical Self-Concept, Exercise Barriers Self-Efficacy, and Body Areas Satisfaction. Overall, changes in the assessed psychological factors demonstrated significant mediation of the association between group membership and exercise session attendance, R² = .23, with only change in Physical Self-Concept scores providing a significant unique contribution. Extensions of this research across different sample types, and with longer durations, were suggested to refine theory and, ultimately, improve exercise adherence treatments.     

New Frontiers in Visual Search: An Exploratory Study in Live Tennis Situations

This study compares the motor skills and physical fitness of school-age children (6-12 years) with visual impairments (VI; n = 60) and sighted children (n = 60). The relationships between the performance parameters and the children's body composition are investigated as well as the role of the severity of the impairment. The degree of VI did not differentially affect the outcomes. Compared to their sighted peers, the children with VI scored lower on the locomotor and object control skills as assessed with the Test of Gross Motor Development-2, and the physical fitness (Eurofit) parameters of plate tapping, the standing broad jump, the modified 5 × 10-m shuttle run, and 20-m multistage shuttle run (20-MST). Their body mass and body fat indexes were inversely correlated with the standing broad jump and the 20-MST, but positively correlated with handgrip strength. Moreover, significant inverse correlations were found between their locomotor and object control skills on the one hand and plate tapping and the 5 × 10-m shuttle run on the other hand. Given the relatively high proportion (25%) of overweight/obese children within the VI sample, educators are recommended to promote health-related activities and help enhance motor skills in this population.     

Variance Estimation for Differential Test Functioning Based on Mantel-Haenszel Statistics

This article concerns the simultaneous assessment of DIF for a collection of test items. Rather than an average or sum in which positive and negative DIF may cancel, we propose an index that measures the variance of DIF on a test as an indicator of the degree to which different items show DIF in different directions. It is computed from standard Mantel-Haenszel statistics (the logodds ratio and its variance error) and may be conceptually classified as a variance component or variance effect size. Evaluated by simulation under three item response models (IPL, 2PL, and 3PL), the index is shown to be an accurate estimate of the DTF generating parameter in the case of the 1PL and 2PL models with groups of equal ability. For groups of unequal ability, the index is accurate under the I PL but not the 2PL condition; however, a weighted version of the index provides improved estimates. For the 3PL condition, the DTF generating parameter is underestimated. This latter result is due in part to a mismatch in the scales of the log-odds ratio and IRT difficulty.     

A Qualitative Study of the Experiences of Counseling Students Who Participate in Mindfulness-Based Activities in a Counseling Theory and Practice Course

This study explored the lived experiences of two cohorts of counselors in training (CITs) who experienced mindfulness-based activities in a counseling theory and practice course. Utilizing Merriam’s Interpretive Qualitative Approach (Merriam 1988, 2002), the data suggested that students perceived the activities to have enhanced their experiences as students and development as counselors. Implications for improving counselor preparation are considered.     

Prediction of attributional consequences in an actual achievement setting

One hundred ninety-six undergraduates who received feedback on a midterm examination participated in this study. A random subgroup formed a cross-validation sample. Through the use of regression analysis, it was found that both objective and subjective performance ratings did not predict subjects' expectancy ratings but did substantially predict their ratings of pride/shame. Inclusion of attributions enhanced prediction of expectancy but not pride/shame ratings of subjects. On the basis of the findings from this study, a partial reformulation of Weiner's attributional model was proposed. In addition, numerous methodological concerns associated with attributional research were examined.     

Visually impaired children: Development and implications for education

This paper examines some of the models used for conceptualizing the possible developmental implications of blindness and severe visual impairment. It takes up the question of the significance in infancy of certain skills and proficiencies, especially motor, that may be impeded by the lack of vision. The paper then addresses such issues for the school age child as access to literacy, with the emphasis being on ways of mitigating the potentially educationally handicapping consequences of visual disability. Educational technology is cited as one of the principal means available to teachers for meeting these challenges, and examples are given of procedures and devices that are being explored. A central argument is that for psychologists, teachers, and educational technologists the search must be to pinpoint the specific and changing needs of the individual learner.     

The Development of Verb Concepts: Children''s Use of Verbs to Label Familiar and Novel Events

The importance of actions, results, and instruments in verb concepts was examined in four studies. Study 1 investigated how children label familiar events for which instrument, action, and result verbs were appropriate labels. In Study 2, subjects were taught novel verbs and were asked to use these verbs to label events in which the instrument, action, or result had been changed. Study 1 showed that 3-year-olds used action verbs more frequently than older children and adults, and that they preferred to use an action verb over a result verb when both verbs were appropriate labels. Instrument verbs were used most frequently as first responses to the events, and were most frequently used by older children and adults. In Study 2, subjects were least likely to use the novel verbs to label events in which the result had changed. This effect increased with age. Action changes had a moderate effect for all age groups, while instrument changes had the weakest effect. Studies 3 and 4 ruled out stimulus salience and a familiar word strategy as interpretations of these findings. The studies are discussed in terms of current theory and research on conceptual development, word-learning strategies, and the semantic organization of nouns and verbs.
