Modeling Dynamic Control in Normal Aging


Complex and dynamic decision making environments are common throughout life, but little is known about how normal aging influences performance on these types of scenarios. To determine performance differences associated with normal aging, we test older and younger adults in a dynamic control task. The task involves the control of a single output variable via multiple and uncertain input controls. A computational model is developed to determine the behavioral characteristics associated with normal aging in a dynamic control task. Older adults exhibit a positivity effect, congruent with previous research. Model based analysis demonstrates a unique performance signature profile associated with normal aging.
