A comparison of BASIC language timing loops for the TRS-80 microcomputer

For users who wish to program the TRS-80 microcomputer exclusively in BASIC, the FOR-NEXT timing loop provides almost twice as fine temporal resolution as the incrementing loop. A temporal resolution of 6.62 msec is possible with the FOR-NEXT loop.     

Applied sport psychology: A view from britain

Abstract

Based on the findings of a field study with youth sport coaches, contextual factors in youth sport arc considered. Youth sport is discussed as a “developmental intervention” (Birkel, Lerner, &; Smyer, 1989). Although past research has examined a variety of issues in youth sport (e.g., coaching behavior, participation motivation), the dynamics of the context have been largely ignored. It is argued that situational factors may have important implications for the quality of children's youth sport experiences. Data arc presented to show the significance of contextual factors in coaches' experiences. Examples of previous interventions aimed at manipulating contexts arc offered and suggestions for future interventions, based on the present study, arc discussed. The roles of parents. spectator location. rules, and time are discussed in detail.     

Athletes' perceptions of how cognitive interference during competition influences concentration and effort

Abstract

This paper investigates athletes' perception of the relationship between cognitive interference and its effects on concentration and effort during sport performance. The sample consisted of 115 volleyball players that took part in a national university tournament. Three different kinds of thoughts were investigated: ‘performance worries’, ‘situation-irrelevant thoughts’, and ‘thoughts of escape’. Path analysis was used to examine the relationships. All kinds of thoughts were reported to be detrimental to concentration, whereas different patterns of associations emerged between different thoughts and subsequent effort. ‘Performance worries’ were reported to be related to increases in effort for athletes holding higher goal attainment expectancies and decreases in effort for athletes holding lower goal attainment expectancies. ‘Thoughts of escape’ were reported to be related to decreases in effort, while no significant relation between ‘situation irrelevant thoughts’ and effort emerged. Results stress the importance of further examining the role of interfering thoughts athletes experience during competition.

The relationship of coping and its perceived effectiveness to positive and negative affect in sport

This article examined the ability of six different coping strategies and their perceived effectiveness in predicting positive and negative affect in sport. Furthermore, it was investigated whether perceived coping effectiveness moderated the influence of coping strategies on affect. British University athletes (N = 356) were requested to recall a recent important competition in their sport when they had a stressful or challenging experience. They were then asked to rate the extent to which they relied on a number of different coping strategies to deal with the situation and the degree to which they found these effective. In agreement with the theoretical predictions of Folkman (1984), problem-focused coping predicted positive affect whereas emotion-focused coping predicted negative affect. Furthermore, for almost all the coping variables, their perceived effectiveness predicted, in a positive way, positive affect and negatively, negative affect. Moreover, the perceived effectiveness of the coping strategies of seeking social support, venting of emotions, and behavioural disengagement, moderated the influence of those strategies on affect. Lastly, a comparison between high and low effective coping groups showed that the former was associated with more pleasant affective experiences.
