Abstract : This grant supported interdisciplinary training (psychology, neuroscience and computer science) of a graduate student (Julie Epelboim), who earned a Ph.D. in Psychology by participating as a graduate Research Assistant on AFOSR Grants 91-0124 & F49620-94-l-0333, entitled "Coordinated action in 3-D Space". Epelboim's doctoral thesis: "Cognitive and Motor Coordination in Visuomotor Tasks", was successfully defended on July 17, 1995 (Ph.D.-degree will be conferred December 1995). The problems studied during AASERT training derived from objectives of the "parent" grants, namely, the test of alternative hypotheses about the control of gaze-shifts associated with arm motions, when an unrestrained, seated subject manipulated objects within arms's reach. Two different mechanistic models had been proposed, namely, (a) an "on-line" feedback model and (b) a ""single packet" model that based accurate gaze control on pre-planned patterns of coordinated movements of the head and eyes. Tests of these alternatives led to support for the first. The second problem studied the speed and accuracy of visually guided hand movements and the correlation of these performance measures with binocular gaze-errors. Much more is now known about this problem thanks in no small measure to Epelboim's contributions. Epelboim's contributions earned her first authorship in a number of important publications
