AnnotationThe effects of old age on the reaction time (RT) decrement associated with task alternation were examined in three experiments. Old age was associated with increased "mixing-cost", which is the RT difference between two conditions: "mixed task", where trials involving two tasks are intermixed; and "single task", where all the trials involved the same task. Old age was also associated with an increasing "switching cost", which is the RT difference between trials in which the task was just changed and trials in which it was repeated. However, old age was associated with an almost intact ability to prepare for an upcoming task switch. (RH).
