Coordination Of Continuous And Discrete Components Of Action, Stephanie L. Kilian

Goal-directed movement may contain discrete and continuous components of action. In this experiment, participants moved back and forth between targets using a computer mouse in a cyclical aiming task. It was of interest to examine the relation between a discrete button press on a computer mouse, indicating an attempt at target capture, and the peak position of the corresponding, continuous movement trajectory of the mouse. How might the spatial and temporal relations between those events vary as a function of variations in task constraints? In particular, this experiment varied the target width (W) and amplitude requirement (A), where variations of …

Neuropsychological performance was measured in chronic alcoholics who maintained abstinence for at least six months and with matched controls. Specifically, measures of verbal memory were assessed utilizing the Rey Auditory Verbal Learning Test (RAVLT) and measures of nonverbal memory with the Rey Osterreith Complex Figure Test (ROCF) and a new measure, the Poreh Nonverbal Memory Test (PNMT). In addition, both the RAVLT and the PNMT provide a measure of operationalized learning, as they are multi-trial tasks utilizing five trials to assess recall in each trial. Verbal memory includes the ability to encode, store and retrieve information for words, language and …

The purpose of this study is to gather data in order to develop new indices to aid clinicians in more accurately distinguishing between patients feigning posttraumatic stress disorder (PTSD) and those with genuine PTSD. Participants were administered a battery of tests that included the Digit Span, Digit Symbol, Trail Making Test (TMT), and Rey Auditory Verbal Learning Test (RAVLT) twice, once while performing genuinely and again while simulating PTSD. The results of this study found that trails 21-25 of part A of the TMT are a good indicator of poor effort. This measurement was found to have high sensitivity (90.7 …
