Laterality Across The Lifespan: The Effects Of Task Complexity, Nicole Williams

Theses and Dissertations (Comprehensive)

The current study aimed to build on the work of Gooderham & Bryden (2013) by comparing the effects of task complexity on hand selection across the lifespan. It was hypothesized that the increasing complexity of a task would override a biomechanically efficient movement such that participants would use only the preferred hand to complete the task. It was also hypothesized that older adults would perform similarly to young children with respect to switch points in space. Four age groups of participants (3-7 year olds, 8-12 year olds, 18-25 year olds and adults over 70 years) completed the newly designed Hand …
