Abstract

Individual differences in Visual Scanning behavior, Heart Rate and Spatial Ability were examined on a Delay and Non-Delay Match-To-Sample task. Mitchell (2005) demonstrated that the direction (Heart Rate acceleration or deceleration) and the magnitude of Heart Rate change represent specific attending behaviors during visual discrimination learning; that is, Heart Rate deceleration is associated primarily with stimulus orientation, whereas Heart Rate acceleration corresponds to stimulus feature comparison. The data from this experiment support that Heart Rate is a valid indicator of attending behavior. Individuals who displayed greater Heart Rate change (acceleration) from baseline solved the Match-To-Sample problems more quickly (had shorter response latencies) and tended to score higher on an intelligence assessment of spatial ability. Also, systematic and exhaustive Visual Scanning resulted in faster Match-To-Sample learning on the Delay task.
