Abstract:
Abstract: Recently, it has been shown that long-term object
priming can occur that is sensitive to changes in both location and
left-right reflection of the primed object. To further specify the
extent of the location specificity of this priming, we presented
probe images in either 1) a location identical to the location of
the prime, 2) in the same visual quadrant as the prime or 3) in a
different visual quadrant than the prime. After naming object
images in a priming phase, the subjects' task was to identify the
object in a rapid visual stream of nonobject distracters. Probe
images presented in the same visual quadrant as the prime image
were identified faster than probe images presented in a different
visual quadrant than the prime image. Within a visual quadrant,
changes in location between prime and probe had no effect on object
identification. These results suggest that the majority of this
priming resides in area V4 (in which receptive fields are limited
to a visual quadrant).
