The Relationship Between Mindfulness and Life Stress in Student-Athletes : The Mediating Role of Coping Effectiveness and Decision Rumination

The role of dispositional mindfulness on stress in student-athletes and factors that mediate this relationship has yet to be examined. Accordingly, the purpose of this study was to investigate the relationships between the facets of mindfulness and life stress in student-athletes and whether these relationships are mediated through coping effectiveness and decision rumination. Participants were 202 student-athletes who completed validated measures of dispositional mindfulness, student-athlete life stress, decision rumination and coping effectiveness in sport. Results indicated that the acting with awareness and non-judging facets of mindfulness were negative predictors of life stress, whereas the observe facet was a positive predictor of life stress. Mediation analyses revealed that these relationships were mediated through coping effectiveness and decision rumination. Findings provide new insight into the role dispositional mindfulness plays on student-athlete perceptions of life stress and implications for practitioners are discussed

The role of pre-performance and in-game emotions on cognitive interference during sport performance: The moderating role of self-confidence and reappraisal

In this research we examined whether prevalent pre-performance (Study 1) and in-game (Study 2) emotions were associated with cognitive interference (i.e., thoughts of escape, task irrelevant thoughts and performance worries), and whether any effects were moderated by reappraisal and self-confidence. In Study 1, we found team sport players’ pre-performance anxiety positively, and excitement negatively, predicted cognitive interference during a competitive match. However, no moderating effects for reappraisal or confidence were revealed. In Study 2, we found that badminton players’ in-game anxiety, dejection and happiness positively predicted, whereas excitement negatively predicted, cognitive interference during a competitive match. Moreover, reappraisal and confidence moderated the relationships for excitement and happiness with task irrelevant thoughts. Our findings underscore the role that pre-performance and in-game emotions can play on athletes thought processing during sport performance, as well as highlight the importance of considering self-confidence and reappraisal on the role of in-game emotions on cognitive interference

The role of reinvestment in performance of simulated laparoscopic surgery under time pressure

Free Communications: Verbal and Poster - Motor Learning and ControlOBJECTIVE: To examine the impact of ‘reinvestment’ on laparoscopic performance under a common intra-operative stressor, time pressure. Background Study of the breakdown of performance under stress has been gaining momentum in the motor skill learning domain as well as domains like aviation and anesthesia, but this has not been the case in the domain of surgery until recently. Research on intra-operative stressors has focused on external factors without considering individual differences in the ability to cope with stress. One individual difference that is implicated in adverse effects of stress on performance is ‘reinvestment’, the propensity for conscious monitoring and control of movements. METHODS: Thirty-one medical students were divided into high and low reinvestment groups based on their scores on the Movement Specific Reinvestment Scale. Participants were first trained to proficiency on a peg transfer task and then tested on the same task in a control and time pressure condition. In the control condition, participants were simply asked to do their best, as they had in training. In the time pressure condition, participants were informed that operating surgeons sometimes are required to perform under time constraints and they should try to complete the task faster than their best time in training (of which they were informed).Outcome measures included generic performance and process measures. Stress levels were assessed using heart rate and the State Trait Anxiety Inventory (STAI). RESULTS: High and low reinvesters demonstrated increased anxiety levels from control to time pressure conditions as indicated by their STAI scores, although no differences in heart rate were found. Low reinvesters performed significantly faster when under time pressure, whereas high reinvesters showed no change in performance times. Low reinvesters tended to display greater performance efficiency (shorter path lengths, fewer hand movements) than high reinvesters. Conclusion Trained medical students with a high individual propensity to consciously monitor and control their movements (high reinvesters) displayed less capability (than low reinvesters) to meet the demands imposed by time pressure during a laparoscopic task. The finding implies that the propensity for reinvestment may have a moderating effect on laparoscopic performance under time pressure.published_or_final_versionThe 2012 Conference of the North American Society for the Psychology of Sport and Physical Activity (NASPSPA 2012), Honolulu, HI., 7-9 June 2012.

Examining Movement-Specific Reinvestment and Performance in Demanding Contexts.

Two experiments examined the roles of the dimensions of movement-specific reinvestment (movement self-consciousness and conscious motor processing) on performance under demanding conditions. In Experiment 1, novice golfers practiced a golf putting task and were tested under low- and high-anxiety conditions. Conscious motor processing was not associated with putting proficiency or movement variability; however, movement self-consciousness was positively associated with putting proficiency and appeared to be negatively associated with variability of impact velocity in low-anxiety conditions, but not in high-anxiety conditions. Increased anxiety and effort possibly left few attention resources for movement self-consciousness under high anxiety. In Experiment 2, participants performed a quiet standing task in single- and dual-task conditions. Movement self-consciousness was positively associated with performance when attention demands were low (single task) but not when attention demands were high (dual task). The findings provide insight into the differential influence of the two dimensions of movement-specific reinvestment under demanding conditions

Dimensions of movement specific reinvestment in practice of a golf putting task

© 2014 Elsevier Ltd. Objectives: This study aimed to investigate the role of the two dimensions of movement specific reinvestment (conscious motor processing and movement self-consciousness) in performance of a complex task early and later in practice. Furthermore, the study also examined the underlying kinematic mechanisms by which conscious motor processing and movement self-consciousness influence performance in practice. Methods: Trait measures of conscious motor processing and movement self-consciousness were obtained from participants using the Movement Specific Reinvestment Scale. Participants (n=30) with no prior golf putting experience practiced 300 golf putts over the course of two days. Putting proficiency (number of putts holed) and variability of movement kinematics (SD impact velocity and SD putter face angle at impact) were assessed early and later in practice. Results: Movement self-consciousness positively influenced putting proficiency early and later in practice by reducing variability of impact velocity and putter face angle at impact. Conscious motor processing positively influenced putting proficiency early in practice by reducing variability of impact velocity and putter face angle at impact. Later in practice, conscious motor processing was not associated with putting proficiency. Conclusion: The findings suggest that higher propensity for movement self-consciousness potentially influences performance early and later in practice by reducing variability of impact velocity and putter face angle at impact. A higher propensity for conscious motor processing benefits performance in a similar manner as movement self-consciousness early in practice but it does not seem to influence performance later in practice. The findings of the current study suggest that movement self-consciousness and conscious motor processing differentially influence performance at different stages in practice of a complex motor skill, suggesting that they might depict different types of conscious processing

Conscious motor processing and movement self-consciousness: two dimensions of personality that influence laparoscopic training.

PublishedResearch Support, Non-U.S. Gov'tBACKGROUND: Identifying personality factors that account for individual differences in surgical training and performance has practical implications for surgical education. Movement-specific reinvestment is a potentially relevant personality factor that has a moderating effect on laparoscopic performance under time pressure. Movement-specific reinvestment has 2 dimensions, which represent an individual's propensity to consciously control movements (conscious motor processing) or to consciously monitor their 'style' of movement (movement self-consciousness). OBJECTIVE: This study aimed at investigating the moderating effects of the 2 dimensions of movement-specific reinvestment in the learning and updating (cross-handed technique) of laparoscopic skills. METHODS: Medical students completed the Movement-Specific Reinvestment Scale, a psychometric assessment tool that evaluates the conscious motor processing and movement self-consciousness dimensions of movement-specific reinvestment. They were then trained to a criterion level of proficiency on a fundamental laparoscopic skills task and were tested on a novel cross-handed technique. Completion times were recorded for early-learning, late-learning, and cross-handed trials. RESULTS: Propensity for movement self-consciousness but not conscious motor processing was a significant predictor of task completion times both early (p = 0.036) and late (p = 0.002) in learning, but completion times during the cross-handed trials were predicted by the propensity for conscious motor processing (p = 0.04) rather than movement self-consciousness (p = 0.21). CONCLUSION: Higher propensity for movement self-consciousness is associated with slower performance times on novel and well-practiced laparoscopic tasks. For complex surgical techniques, however, conscious motor processing plays a more influential role in performance than movement self-consciousness. The findings imply that these 2 dimensions of movement-specific reinvestment have a differential influence in the learning and updating of laparoscopic skills.This work was supported by a GRF grant from the Research Grants Council, University Grants Committee, Hong Kong (HKU752211H)
