Influences of Recognition on Direct and Indirect Measures of Memory

Malingering, the exaggeration of symptoms for secondary gain, is a serious threat to neuropsychological practice and diagnosis validity, as well as a drain on mental health funding. Performance validity tests, which measure level of effort, have become a standard practice in testing batteries. However, they can be susceptible to implicit factors such that they can be willfully failed at chance or above-chance levels. Eyetracking represents a way to obtain objective implicit measurements of recognition memory faster than behavior responses. This project will measure eye movements and pupil dilation with regard to learned and unlearned stimuli in controls and those instructed to simulate memory impairment. The objective is to determine if an eyetracking recognition test can be used to detect the presence of malingering. Data from both groups will be compared on a variety of eye behavior and behavioral response variables.
