SPONSOR/MONITOR'S REPORT NUMBER(S) DISTRIBUTION / AVAILABILITY STATEMENT Approved for Public Release; Distribution Unlimited SUPPLEMENTARY NOTES ABSTRACT The ability to accurately and efficiently monitor the neurocognitive status of US warfighters under diverse operational and experimental conditions is of critical importance to the ongoing mission and network-centered initiatives of the United States military. The Automated Neuropsychological Assessment Metrics (ANAM) is a computer assisted tool for evaluating neurocognitive performance with demonstrated effectiveness for application in diverse military operational and research testing scenarios. The primary objective of this project is to examine select psychometric and administration properties of the newlyreleased ANAM4. Four studies are proposed that will 1) examine common use practices and determine the effect of specific administration procedures on ANAM4 performance, 2) assess the test-retest reliability of individual ANAM4 tests, 3) examine the validity of the ANAM4 mood scale, and 4) develop a representative normative dataset for Army National Guard service members. Data collection is complete for Studies 1, 2 and 3; data analysis and manuscript preparation is underway for all three studies. Data collection is underway for Study 4. 15.

Assessment of dynamic predictive timing with indices of visuo-motor synchronization during circular ocular pursuit. Behavior Research Methods, under review. Abstract When visually tracking a moving target, spatial and temporal predictions are used to circumvent the neural delay required for the visuo-motor processing. However, the internally generated predictions must be synchronized to the external stimulus during continuous tracking. We examined the utility of a circular visual tracking paradigm for assessment of predictive timing using normal human subjects. Disruptions of gaze-target synchronization were associated with anticipatory saccades that caused the gaze to be temporarily ahead of the target along the circular trajectory. These anticipatory saccades indicated preserved spatial and temporal prediction but suggested that the timing of the execution of the temporal prediction, i.e. predictive timing, was impaired. We quantified gaze-target synchronization with several indices, whose distributions across subjects were such that instances of extremely poor performances were identifiable outside the margin of error determined by test-retest measures. Because predictive timing is an important element of attention functioning, the visual tracking paradigm and indices described here may be useful for attention assessment.
