The objective of the present study was to examine the different kind of switch costs among a varied population using a modified bimanual serial reaction time task. Alternating between responses produce a cost of increased response time, which is termed a switch cost. However, not all switch costs are equal, and its effect on response time is dependent on what previous hand and digit combination was utilized. A detachable touchscreen tablet PC running a custom built JavaScript based software prompted participants to press down with their digits (2nd-5th) to corresponding buttons which would light up in …

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 …
