Abstract
Cognitive processes that underlie working memory (WM), attention,
and awareness are closely intertwined. 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.
