The mediating effect of peripheral narrowing in the negative life event stress (N-LES)/athletic injury relationship was investigated. LES and other psychosocial variables were measured, and peripheral vision was assessed in nonstressful (practice day) and stressful (game day) sport situations. Results showed that total LES, N-LES, and psychological coping skills significantly contributed to the prediction of the occurrence of athletic injury. Additionally, psychological coping skills buffered the N-LES/athletic injury relationship. Peripheral narrowing during stress significantly mediated 8.1% of the N-LES/athletic injury relationship. The findings support the predictions of the model of stress and injury, provide evidence for peripheral narrowing as a mechanism in the LES/athletic injury relationship, and suggest directions for future research examining mediating effects in the model of stress and injury.

Anxiety, Expertise, and Visual Search Strategy in Karate
A. Mark Williams and David Elliott
The effects of anxiety and expertise on visual search strategy in karate were examined. Expert and novice karate performers moved in response to taped karate offensive sequences presented under low (LA) and high anxiety (HA). Expert performers exhibited superior anticipation under LA and HA. No differences were observed between groups in number of fixations, mean fixation duration, or total number of fixation locations per trial. Participants displayed scan paths ascending and descending the centerline of the body, with primary fixations on head and chest regions. Participants demonstrated better performance under HA than under LA. Anxiety had a significant effect on search strategy, highlighted by changes in mean fixation duration and an increase in number of fixations and total number of fixation locations per trial. Increased search activity was more pronounced in novices, with fixations moving from central to peripheral body locations. These changes in search strategy with anxiety might be caused by peripheral narrowing or increased susceptibility to peripheral distractors.

partially attribute this outcome to a tunnel vision effect brought on by physical fatigue known as “peripheral narrowing,” or an inability for a person to recognize cues in their peripheral visual field ( Ando et al., 2008 ). This research describes how physical fatigue may serve as an organismic constraint
