The effects of the intertrial interval on a visual imagery task

Stearns, Branka Prazich January 1980 (has links)
This experiment was initially inspired by the visual imagery studies of R.J. Weber and colleagues (1969, 1970, 1972). The purpose of the present study was to examine various aspects of mental fatigue associated with the forming of mental images as suggested by Weber and Castleman (1970).A total of 45 undergraduates were given 10 trials on the Weber Alphabet Task (Weber and Kelley, 1969) which involves mental imagery, The experimental design compared three inter-trial interval periods, 0 sec, 10 sec, and 30 sec, on speed and accuracy of performance. The results indicated that the more trials a subject completed, the faster he was able to complete later trials, regardless of the intertrial interval. However, on the error data, the effedt of the intertrial interval was significant. It was demonstrated that the 0 sec intertrial interval group made most errors on the imagery task when compared to the other two groups.

The pupillary response as an indicator of fatigue : a study of task-induced effects

Christie, Carol A. January 1981 (has links)
Previous studies of cognitive fatigue which have used the pupillary response have centered on long term, time-induced effects. Results have indicated that pupil diameter decreases as a function of cognitive fatigue. This study examined the effects of short term, task-induced fatigue on the pupillary response.The research design involved the use of a pre/post paradigm with an interpolated mental multiplication task designed to produce cognitive fatigue. Pupil diameter and rating scale measures were obtained, as well as a measure of the subjects' numerical aptitude. By analyzing the pre/post differences in pupil diameter over time, the use of the pupillary response for the assessment of short term, task-induced cognitive fatigue was demonstrated to be feasible.
