Working Memory Performance Across Development And Following Acute Exercise, Patrice L. Stering
Working Memory Performance Across Development And Following Acute Exercise, Patrice L. Stering
Masters Theses 1911 - February 2014
This thesis investigates the developmental trajectory of visuo-spatial working memory as well as the potential influence of acute exercise on working memory performance. Individuals between the ages of 6 and 25 years were randomly assigned to a 30-minute bout of exercise on an elliptical trainer or to a no-exercise control condition. Participants then performed a computerized N-back task to assess working memory. Developmental results suggest that working memory ability continues to develop into early adulthood with the exact trajectory depending on the cognitive demand of the task being assessed. No difference in working memory performance was found between the exercise …

Posture becomes integrated with other goal-directed behaviors early in infancy and continues to develop into the second decade of life. However, the developmental time course over which posture is stabilized relative to the base of support during a dynamic manual precision task has not been examined. Postural-manual integration was assessed in 7-year-olds, 10-year-olds, and adults using a postural-manual task in which task precision (target fitting size) and postural difficulty (reaching distance to a target) were manipulated. The main dependent variable was postural time-to-contact (TtC). Results indicated systematic age effects in which TtC was shortest in the 7-year-olds, increased in the …
