Relationship between Cognitive Ability and the Iconic Processing of Spatial and Identity Information

摘要

The present investigation established the reliability of a classification technique which separates subjects into groups based on individual differences in the ability to process spatial location and identity information from tachistoscopically presented displays. Performance of the two groups then was compared on an iconic processing task which required the simultaneous processing of both location and identity information. Results indicated those subjects who process location information well performed significantly better on the Averbach-Coriell bar probe task than subjects who process identity information well. Subjects also were administered a battery of cognitive tests to determine whether differences at the iconic level are related to performance at more molar levels of cognition. Results of a series of correlational analyses indicated that a relationship does exist between iconic ability and more molar cognitive abilities.
