进行了两项研究，以调查是否有意义的任务转换结构可以确定，如果是这样，以确定它是如何与高阶认知的措施和成年年龄。这两项研究都表明，任务切换的措施是适度相关的不同组合的任务和切换结构可以区分从一个结构反映处理速度。第二项研究的结果表明，虽然任务转换结构与年龄和情景记忆，归纳推理和空间视觉化的措施有关，大多数转换结构与年龄和其他认知措施之间的关系与其他变量共享。
Two studies were conducted to investigate whether a meaningful task-switching construct could be identified and, if so, to determine how it was related to measures of higher order cognition and to adult age. Both studies revealed that measures of task switching were moderately correlated across different combinations of tasks and that a switching construct could be distinguished from a construct reflecting processing speed. The results of the 2nd study revealed that although the task-switching construct was related to age and to measures of episodic memory, inductive reasoning, and spatial visualization, most of the relations between the switching construct and both age and other measures of cognition were shared with other variables.
