Abstract:
Abstract: We investigated the influence of pictures,
presented both in peripheral and central portions of the visual
field, on a subsequent word-stem completion task. Well
characterized line-drawing pictures (Snodgrass & Vanderwert,
1980) were presented in sets of ten, either in the center, left, or
right visual field. A dual purkinje image eyetracker coupled with a
stimulus deflector was used to control for eye movements by
retinally stabilizing the image, and thus ensuring consistent
central and peripheral presentations of the pictures. Following
each set of ten pictures, participants received a list of 20
three-letter word-stems to complete. Ten stems were from the
pictures just presented and served as primed test stems, ten were
from pictures not presented and served as non-primed control stems.
There was a significant difference between percentage of completed
primed and unprimed word-stems (F = 7.113, p < .02), with
participants completing ~10% more primed stems. There was no
significant difference between stems primed with central
presentations and stems primed with peripheral presentations (F =
1.25, p < .29). These data demonstrate that pictures can
effectively serve as word primes, and that such priming in the
peripheral visual field is comparable to priming in the central
visual field.
