Response Devices and Cognitive Tasks

Abstract

This report is for two years of research conducted primarily at the Air Force Armstrong Laboratory, Project Lamp. The aims of the research were to (1) study the effects of response mode and response complexity on basic cognitive tasks, and (2) to use the information obtained to develop more elaborated models of cognitive functioning which take these factors into account. Subjects were tested on a set of computer-administered cognitive tasks, using both keyboard and touchscreen response modes, and under varying sets of response load conditions. The results clearly show tha response load has a substantial effect on the performance of cognitive tasks. A detailed investigation of the effects of response load in choice reaction time showed that Hick's Law, formerly attributed to cognitive decision factor related to task complexity, is largely due to response factors.
