We examined distraction and attentional narrowing in a dual-task auto-racing simulation. Participants were randomly assigned to six groups: distraction control, distraction anxiety, relevant control, relevant anxiety, central control, and central anxiety. Those in central conditions performed a driving task; the other four groups identified peripheral lights in addition to driving. Irrelevant peripheral lights were included in distraction conditions. Participants in anxiety conditions were exposed to increasing levels of anxiety via a time-to-event paradigm. In 3 sessions of 20 trials, measures of cognitive anxiety, arousal. visual search patterns, and performance were recorded. At higher levels of anxiety, the identification of peripheral lights became slower and less accurate. and significant performance decrements occurred in central and peripheral tasks. Furthermore, visual search patterns were more eccentric in the distraction anxiety group. Results suggest that drivers who are highly anxious experience an altered ability to acquire peripheral information at the perceptual level.

There has been a notable increase in research on aging and physical activity in recent years. Most of this research derives from the natural sciences, using quantitative methods to examine the consequences of the physically aging body. Although these investigations have contributed significantly to our knowledge, to further understand the complex meanings attached to physical activity we also need social-science research. The article explores how a variety of social scientists (positivisls, postpositivists, interpretive social scientists, critical social scientists, poststructuralists, and postmodernists) who use quantitative and qualitative methods approach physical activity and aging. Through examples from research on aging and physical activity, the authors highlight the differences, possibilities, and limitations of each research approach. Their intention is not to declare one research approach superior to any other but to increase awareness and acceptance of different paradigms and to encourage dialogue between those who study aging and physical activity from a variety of perspectives.

Over the past few years, attention has been drawn to the importance of neighborhood influences on physical activity behavior and the need to consider a multilevel analysis involving not only individual-level variables but also social-and physical-environment variables at the neighborhood level in explaining individual differences in physical activity outcomes. This new paradigm raises a series of issues concerning systems of influence observed at different hierarchical levels (e.g., individuals, neighborhoods) and variables that can be defined at each level. This article reviews research literature and discusses substantive, operational, and statistical issues in studies involving multilevel influences on middle-aged and older adults’ physical activity. To encourage multilevel research, the authors propose a model that focuses attention on multiple levels of influence and the interaction among variables characterizing individuals, among variables characterizing neighborhoods, and across both levels. They conclude that a multilevel perspective is needed to increase understanding of the multiple influences on physical activity.

As part of the emergence of alternative research paradigms in exercise and sport psychology, we draw upon data from an ethnographic study of 3 individuals with schizophrenia to explore the use of exercise as an adjunct therapy for schizophrenia. A 10-week exercise program of twice-weekly sessions was implemented. Participant observation and interviews with participants and their assigned key-workers were the primary sources of data collection used. The influence of exercise on the lives of participants and their mental health and the underlying mechanisms of change were explored. Our findings indicate that exercise has the potential to help reduce participants’ perceptions of auditory hallucinations, raise self-esteem, and improve sleep patterns and general behavior. The process of exercising, via the provision of distraction and social interaction rather than the exercise itself, was very influential in providing these benefits. In conclusion, we strongly recommend the inclusion of exercise as an adjunct treatment in psychiatric rehabilitation.

Embedded in the self-determination theory (Deci & Ryan, 2000) framework, we obtained self-report data from 418 paid and voluntary coaches from a variety of sports and competitive levels with the aim of exploring potential antecedents of coaches’ perceived autonomy supportive and controlling behaviors. Controlling for socially desirable responses, structural equation modeling revealed that greater job security and opportunities for professional development, and lower work–life conflict were associated with psychological need satisfaction, which, in turn, was related to an adaptive process of psychological well-being and perceived autonomy support toward athletes. In contrast, higher work–life conflict and fewer opportunities for development were associated with a distinct maladaptive process of thwarted psychological needs, psychological ill-being, and perceived controlling interpersonal behavior. The results highlight how the coaching context may impact upon coaches’ psychological health and their interpersonal behavior toward athletes. Moreover, evidence is provided for the independence of adaptive and maladaptive processes within the self-determination theory paradigm.

This study examined the interaction between a skill/extraneous attentional focus and an internal/external focus of attention using a dual-task paradigm. Thirty-two low-skill participants completed a primary dart-throwing task with their dominant arm while simultaneously performing a secondary arm-stabilizing task with their nondominant arm. Two aspects of the participants’ attentional focus were manipulated: skill versus extraneous focus and external versus internal focus. Participants completed 120 trials across four conditions created by combining the dimensions of the two variables. Performance on the primary task was assessed by measuring throwing accuracy and the kinematics of the throwing action. Results indicated that accuracy improved under the external, skill-oriented condition relative to all other conditions; no differences between the remaining conditions were observed. These findings suggest that an external, skill-oriented focus of attention is needed to facilitate performance improvements in novices.

Nearly 200 studies have examined the impact that either acute or long-term exercise has upon cognition. Subsets of these studies have been reviewed using the traditional narrative method, and the common conclusion has been that the results are mixed. Therefore, a more comprehensive review is needed that includes all available studies and that provides a more objective and reproducible review process. Thus, a meta-analytic review was conducted that included all relevant studies with sufficient information for the calculation of effect size (N = 134). The overall effect size was 0.25, suggesting that exercise has a small positive effect on cognition. Examination of the moderator variables indicated that characteristics related to the exercise paradigm, the participants, the cognitive tests, and the quality of the study influence effect size. However, the most important finding was that as experimental rigor decreased, effect size increased. Therefore, more studies need to be conducted that emphasize experimental rigor.

Failures of awareness are common when attention is otherwise engaged. Such failures are prevalent in attention-demanding team sports, but surprisingly no studies have explored the inattentional blindness paradigm in complex sport game-related situations. The purpose of this paper is to explore the link between breadth of attention, inattentional blindness, and tactical decision-making in team ball sports. A series of studies revealed that inattentional blindness exists in the area of team ball sports (Experiment 1). More tactical instructions can lead to a narrower breadth of attention, which increases inattentional blindness, whereas fewer tactical instructions widen the breadth of attention in the area of team ball sports (Experiment 2). Further meaningful exogenous stimuli reduce inattentional blindness (Experiment 3). The results of all experiments are discussed in connection with consciousness and attention theories as well as creativity and training in team sports.

Three experiments examined the relative efficacy of different imagery perspectives on the performance of tasks in which form was important. In Experiment 1,25 experienced karateists learned a new kata using either external or internal visual imagery or stretching. Results indicated that external visual imagery was significantly more effective than internal visual imagery, which was significantly more effective than stretching. In Experiment 2, 40 sport science students learned a simple gymnastics floor routine under one of four conditions: external or internal visual imagery with or without kinesthetic imagery. Results revealed a significant main effect for visual imagery perspective (external visual imagery was best) but no effect for kinesthetic imagery. Experiment 3 employed the same paradigm as Experiment 2 but with high-ability rock climbers performing difficult boulder problems. Results showed significant main effects for both visual imagery perspective (external visual imagery was best) and kinesthetic imagery. The findings are discussed in terms of the cognitive processes that might underlie imagery effects.

The effect of exercise on negative affect has been examined in hundreds of studies. However, the effect of exercise on diagnosed clinical depression has received far less attention. Furthermore, poor methodological techniques predominate and results have been conflicting. A meta-analysis was conducted to investigate the effect of exercise on clinical depression and depression resulting from mental illness. The chosen studies examined the effect of a chronic exercise paradigm (independent variable) on depression (dependent variable). Each study’s variables were coded: design, subjects, exercise, and dependent measure characteristics that could moderate the effect of exercise on depression. Moderator variables were analyzed using analysis of variance (ANOVA). Results from 30 studies showed an overall mean effect of −.72. Therefore, individuals who exercised were −.72 of a standard deviation less depressed than individuals who did not exercise. Moderating variables and implications for the prescription of exercise as an effective treatment for depression are discussed.
