| Research Abstract |
It is known that, when attention is directed toward a particular location, attention tends to spread over a whole object/group region that includes the location.The present study examined attention-spreading for emerging objects, by using event-related brain potentials with a high temporal resolution of brain activities. According to results in several experiments, we identified three attention processes: attention-spreading for groups represented as figures against the background at around 150 ms post-stimulus, selection of parsing objects at around 250 ms, and an interaction process between top-down attention and attention-spreading at around 350 ms. We also found that these processes have systematic individual differences.
