Individual differences and ergonomic factors in performance on a videotex-type task

Abstract

This study manipulated ergonomic aspects of a videotex–type task and attempted to relate paper and pencil measures of field dependence-independence, intelligence, capacity to complete a computer science curriculum and attitudes toward computers, to the performance of novice users. Results indicated that fault-tolerant aspects of the software and the use of self–defined commands resulted in superior performance. In addition, field independence and higher intelligence were associated with better performance. No substantial relationship was found between ability to complete a computer science curriculum and performance on the task. Those subjects who expressed an ‘awesome’ view of the nature of computers appeared to perform less well and it was suggested that this may be related to their lack of experience, although it was not possible to statistically verify this interpretation.
