Abstract:

In the current study, we investigated whether
visual salience attracts attention in a bottom-up manner.
We presented abstract and depictive paintings as well as
photographs to naıve participants in free-viewing (Experiment
1) and target-search (Experiment 2) tasks. Image
salience was computed in terms of local feature contrasts in
color, luminance, and orientation. Based on the theories of
stimulus-driven salience effects on attention and fixations,
we expected salience effects in all conditions and a characteristic
short-lived temporal profile of the salience-driven
effect on fixations. Our results confirmed the predictions.
Results are discussed in terms of their potential
implications.
