In many practical situations involving data presentation the human operator is called upon merely to check-read or "monitor" instrument dials. Such monitoring involves relatively simple perceptual repsonses to specific aspects of rapidly changing stimuli. Previous studies of perceptual set in the present series have been concerned with more complex perceptual responses (identification) in relatively static conditions, such as frequently characterize operational situations. Accordingly, an experiment was designed to learn the effectiveness of setting cues as an aid to accuracy of dial-checking when subjects were simultaneously performing a competing visual motor task. Degree of setting and sense channel of cuing were the experimental variables. The results indicate that dial-checking accuracy was significantly improved by the introduction of setting cues. Performance on the competing task was unaffected by the setting operations. Sense channel of cuing was not a significant factor, a suprising finding in view of the "crowded" visual channel resulting from the employment of the two simultaneously visually controlled tasks.
