Sustained Attention and Response Rate as a Function of Task Difficulty and Feedback Arrangements.
Snelbecker, Glenn E.; And Others
Two studies were performed to evaluate the extent to which response patterns and sustained attentiveness is a function of the demands of a secondary task, primary task difficulty, and feedback arrangements. The first study varied primary task stimulus difficulty level, feedback arrangements on the primary task, and presence of the secondary task. The main objective of the second study was to determine whether primary task feedback arrangements would interact with secondary task demands to influence attentiveness to the primary task; thus, primary task difficulty was held constant, and primary task feedback arrangements and secondary task difficulty level were varied. Results showed that subjects were able to detect changes in stimuli used in the primary task and to detect presentations of the secondary stimuli, although apparently subjects were not consistently attending to stimulus characteristics. Further, there seemed to be some dimunition in attention to stimulus characteristics and a greater reliance on feedback whenever feedback was available on the primary task. Overall, results suggest the need for multilevel model of attention and that it is not sufficient to conceive of stimulus control in a unitary sense. (SH)
