In a previous study, Egly, Driver, and Rafal (1994) observed both space-and object-based components of visual selective attention. However, the mechanisms underlying these two relationship between them are not well understood. present research, with similar paradigm, issues were addressed by manipulating cue validity. Behavioral results indicated presence under high validity, to Egly et al.'s study. addition, low space-based component was absent, whereas maintained. Further event-related potential demonstrated an effect at sensory level over posterior areas brain, anterior region. The data suggest that reflect mainly voluntary reflexive mechanisms, respectively.
