摘要：Visual search functions require visual attention for the detection of particular stimuli from large amounts of information. In a state of storing a target stimulus, visual search is performed to determine whether the stimulus in front of the eye is a target stimulus. Therefore, the number of stimuli to remember is believed to affect performance of the task. This study examined the effects of memory load on visual search using the cancellation task. Participants were 28 healthy adults. Participants performed six type cancellation tasks consisting of the number of target types: 1–6. Results showed that canceling efficiency became lower as the error increased and that the time to completion is prolonged by an increase in the number of target types. The effects of increasing the memory load on the visual search showed strong correlation in the logarithmic function, which suggests that when the target types are few, the effect of the number of target types on the task performance is strong, but for numerous target types, the effect of the number of target types on the task performance is weak.
