Visual attention can be manipulated by temporal and spatial factors of stimuli. The purpose of this study is to investigate the underlying mechanism of visual spatial attention of healthy subjects through event-related potential (ERP) study.The subjects of the study were 17 healthy adults, mean age 23.3 years. The visual stimuli were generated by the Neurostim system and presented in groups of eight under three different conditions: cueing (valid, invalid), delay (100 ms, 800 ms) and visual field sides (right and left). ERPs were recorded by 10 Neuroscan systems electrodes placed on each subject's scalp. The latencies and amplitudes of ERPs …
