Inhibitory function in the stimulus-response compatibility task.

Changes of a location-based inhibitory function were investigated by performing a Stimulus-Response Compatibility task under two conditions. This task allows study of the efficiency of the inhibitory function by analyzing differences in error rates and in response time under various conditions of stimulus and response compatibility. In Exp. 1, with 28 college students, the effect of a dual task on the Stimulus-Response Compatibility effect was examined. In a dual-task, a predetermined stimulus such as a color is identified and the number of times a color is displayed is counted. In this experiment, under a dual task using visual stimuli, a decline in error responses and reduction of the Stimulus-Response Compatibility effect were observed. In Exp. 2, 29 college students participated in an identical experiment with the exception that an auditory stimulus was presented as the dual task. Similar to Exp. 1, there was a significant reduction in the number of error responses in the dual-task condition. Conversely, there was no significant change in Stimulus-Response Compatibility effect as estimated by response time. These results suggest that the two visual pathways as proposed by Goodale (1995) and the evocation of intentional attention may affect the Stimulus-Response Compatibility effect.

Inhibition of return using location discrimination in two age groups.

The present study investigated "inhibition of return" which refers to increased response latency when the target in a location discrimination task appears in the same location on consecutive trials. Research to date has suggested that this effect is little changed across age. However, this study, which compared 12 older adults in good health (M=73.0, SD=5.3) with younger adults using the target-target paradigm to examine inhibition of return, suggests there is a strong and continuous effect in older adults in comparison to younger adults. Results indicate the possibility that the inhibitory function may become stronger at an older age.

Inhibition of return using discrimination of location.

The present study investigated "inhibition of return" which refers to increased response latency when the target in a location discrimination task appears in the same location on consecutive trials. Location discrimination tasks were performed by 28 university students (19-21 years of age) in two experiments. In Exp. 1 the task was to press a left or right button in response to a stimulus displayed on a computer screen. The first condition manipulated stimulus-response compatibility which resulted in changing the inhibition of return. Inhibition of return was stronger when the condition was stimulus-response incompatibility. This result shows that inhibition of return functions strongly under incompatible conditions. A second condition required performance of dual tasks in Exp. 2. Again, changes in inhibition of return were seen. These results show that inhibition of return functions strongly under both dual task and incompatible conditions. Inhibition of return was interpreted as functioning strongly when the task was more difficult.
