This study examined cross-task compatibility and aging on dual-task and task-switching performance. Koch and Prinz' (2002) work on cross-task compatibility suggests that response code activation improves performance when dual tasks are performed. That is, switching from a first task to a second task has a greater performance benefit when both tasks share the same specific response code. The role of aging on cross-task compatibility effects was examined in this dissertation. Three specific hypotheses were examined. The first hypothesis was that the method used in Experiment 1 would replicate the cross-task compatibility effects found in Koch and Prinz (2002). The second hypothesis was that older adults would demonstrate a comparable, if not better, benefit from cross-task compatibility as younger adults (both Experiments 1 and 2). The third hypothesis was that increased stimulus-stimulus compatibility would have a positive performance effect on the cross-task compatibility effect (Experiment 2). The results of Experiment 1 were consistent with the findings of Koch and Prinz, thus supporting Hypothesis 1. In regards to Hypothesis 2 for Experiment 1 and 2, older adults demonstrated a benefit for cross-task compatibility. There was no significant interaction between age and compatibility which suggested that the benefit for older adults from compatibility was not different from the benefit received for younger adults. Experiment 2 tested the 3rd hypothesis. The results of Experiment 2 demonstrated that on cross-task compatible trials when there is a further compatible element between the stimuli (stimulus-stimulus compatibility) on both tasks there is not a greater benefit for reaction time performance than cross-task compatibility alone. The results of these two experiments were discussed in terms of benefits to task-switching and the implications for task-switching and aging.
