Mapping the structure of perceptual and visual-motor abilities in healthy young adults.
Repository Usage Stats
The ability to quickly detect and respond to visual stimuli in the environment is critical to many human activities. While such perceptual and visual-motor skills are important in a myriad of contexts, considerable variability exists between individuals in these abilities. To better understand the sources of this variability, we assessed perceptual and visual-motor skills in a large sample of 230 healthy individuals via the Nike SPARQ Sensory Station, and compared variability in their behavioral performance to demographic, state, sleep and consumption characteristics. Dimension reduction and regression analyses indicated three underlying factors: Visual-Motor Control, Visual Sensitivity, and Eye Quickness, which accounted for roughly half of the overall population variance in performance on this battery. Inter-individual variability in Visual-Motor Control was correlated with gender and circadian patters such that performance on this factor was better for males and for those who had been awake for a longer period of time before assessment. The current findings indicate that abilities involving coordinated hand movements in response to stimuli are subject to greater individual variability, while visual sensitivity and occulomotor control are largely stable across individuals.

NOTE: As of 8/1/2015 Dr. Mitroff and his lab will move to The George Washington University in Washington D.C. Lab focus: My lab has an active interest in visual search—how we find targets amongst distractors. With a dual goal of informing both academic theory and applied "real-world" performance, we explore various influences on search. We work with a variety of expert groups to understand the effects of experience and expertise, and to reveal individual differences in performa
