Developmental changes in oculomotor control and working-memory efficiency

In the present study, we examined the developmental changes in the efficiency of saccadic inhibitory control. More specifically, the contribution of age-related changes in working-memory engagement was investigated. We manipulated the efficiency of inhibitory oculomotor control in antisaccade tasks by using fixation-offset conditions, which are supposed to affect inhibitory demands, and by adding increasing working-memory loads to the antisaccade task. In general, in comparison to antisaccade performance of adults, the antisaccade performance of 8-year-old and 12-year-old children was characterized by an increase in direction errors, and/or longer saccadic onset latencies on correct antisaccades. However, this pattern was not altered by the fixation-offset manipulations. In contrast, increased working-memory demands deteriorated 8-year-olds' antisaccade performance unequally as compared to older children and young adults. These findings suggest that - at least in young children - the available functional working-memory capacity is engaged in oculomotor inhibition.     

A DEFENSE OF BUDDHISM,MEDITATION, AND FREE WILL: A THEORY OF MENTAL FREEDOM

This is my response to the criticisms of Gregg Caruso, David Cummiskey, and Karin Meyers, in their roles as members of the “Author Meets Critics” panel devoted to my book, Buddhism, Meditation, and Free Will: A Theory of Mental Freedom at the 2019 annual meeting of the Eastern Division of the American Philosophical Association, organized by Christian Coseru. Caruso's main objection is that I am not sufficiently attentive to details of opposing arguments in Western philosophy, and Cummiskey's and Meyers’ objections, similarly, are that I am insufficiently attentive to details of Buddhism. I argue that all such objections, however putatively correct, do not rise to the level of objections that actually undermine my account of mental freedom.     

Gender differences in sport involvement: Applying the eccles' expectancy-value model

Abstract

With the growth of the field of sport psychology has come a growing interest and concern over gender differences in achievement and participation in various sports. Why do girls and boys differ from one another in their participation rates and participation patterns in sports? Over the past 10 years, Eccles and her colleagues have put together a theoretical model for analyzing the motivational factors underlying individuals' decisions regarding achievement-related choices. This paper describes this theoretical model and uses data from two studies, one focusing on adolescents, and one focusing on elementary school-aged children, to evaluate the utility of this model for understanding gender differences in sport participation. It reaches the following conclusions: (a) the Eccles et al. model holds for sport as well as, if not better than, it does for academic subjects; (b) gender differences in children's attitudes toward sport are quite strong and emerge at a very young age; and (c) these gender differences seem to be a consequence more of gender-role socialization than of “natural” aptitudinal differences.     

Decreasing household television time: a pilot study of a combined behavioral and environmental intervention

Excessive TV viewing is associated with weight gain across the lifespan; thus developing strategies to decrease household viewing time may be an effective obesity prevention approach. This pilot study (n = 6 families) examined the feasibility and short‐term impact of a 2‐pronged environmental plus behavioral approach designed to reduce TV time in the entire family. The environmental manipulation involved placing TV Allowances (programmed to turn off power after family members had watched 75% of their baseline hours) on all TVs in the home. A kit with behavioral strategies for reducing TV time was also sent to the home each week and family members self‐monitored viewing time. Viewing was objectively assessed with the TV Allowances at baseline and at 8 weeks. A significant decrease in objectively measured TV viewing hours was observed, t(5) = 3.1, p = 0.03, 29.8 ± 10.3 versus 14.9 ± 6.0 h (equivalent of decreasing from 7.5 to 3.7 h per day). Fifty percent of families reduced their viewing time by ≥50%. The acceptability of the intervention was high, with 100% of families reporting they would recommend the TV Allowances to others. Further research is needed to test the long‐term efficacy of the program and its impact on weight. Copyright © 2006 John Wiley & Sons, Ltd.     

Individual and common components of the social environment at work and psychological well-being

Interpretations of correlational research on the social origins of psychological well-being are limited by the possibility of reciprocal influences between persons and their social situations and by respondent bias. These issues are addressed in a study of the relation between the social environment at work and mental health. Two components of a social environment were measured: a common social environment, the social climate shared by employees in the same work setting. The study related (a) averaged co-workers' ratings and individuals' own ratings of the social environment to (b) individuals' self-reported psychological well-being. A group of 37 bank branches represented work environments, and nonmanagerial personnel in the branches served as participants. Results indicated that the quality of the social environment at work is related to the mental health of employees. More important, the relation was confirmed with an independent measure of the social environment. Aggregate co-worker ratings of the common social environment were significantly correlated with individual depression and anxiety. However, an individual's perceptions appeared to mediate the social environment's impact. As hypothesized, well-being was more closely tied to the proximal individual social environment than to the more distal common social environment.
