Here we inquired about the functional roles of and interactions among visual awareness, attention, and WM in a series of experiments. With a visual pop-out paradigm, we show that even though subjects were not aware of a suppressed pop-out display, their subsequent performance on an orientation discrimination task was significantly better at the pop-out location than at a control location. By measuring the probability and the time it took for a pop-out display to break suppression, we further discovered that the probability of a location being firstly perceived increases significantly when a pop-out target was present in that location. With an object-tracking paradigm, we show that orientation discriminability at locations near the final position of an invisible moving object was significantly better than that at distal locations. However, orientation discriminability at the on-trajectory location was not significantly different from that at a nearby off-trajectory location. These findings indicate that a pop-out target or moving object can still attract attention when presented subliminally. In contrast, the dynamic trajectory of an invisible object may not be monitored and maintained in visual WM. References Hsieh, P.-J., and Colas, J.T. (in press).
