Activation theory and task design: An empirical test of several new predictions

Abstract

Presents predictions from activation theory concerning task design and modifies activation theory to (a) account for the frequent empirical finding that relatively nonstimulating tasks cause elevated arousal levels and (b) allow for effects of individual differences on task-characteristics/task-response relationships. An experiment was conducted with 54 undergraduates to test the hypotheses that (a) a relatively nonstimulating task would cause more negative reactions (increased arousal, decreased satisfaction) than a moderately high-stimulating task; (b) electrodermal lability and extraversion would moderate task-stimulation-level/task-response relationships; and (c) there would be inverted- U relationships between activation levels and performance. Ss completed the Eysenck Personality Inventory Extraversion scale, were familiarized with physiological recording equipment, and then participated in a nonstimulating or a stimulating task while connected to the equipment. Ss then completed measures of task satisfaction, activation level, and perceptions of task characteristics (Job Diagnostic Survey). Modest support for each of the hypotheses was obtained. Activation theory is discussed as an explanation for the process that intervenes between task stimulation and responses of task performers.
