The effects of the intertrial interval on a visual imagery task

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.
