Cascaded acquisition of spatial contextual cueing

Spatial contextual cueing refers to the facilitation of visual search when invariant spatial configurations of the target and distractors are learned. Using the instance theory of automatization and the reverse hierarchy theory of visual perceptual learning, this study explores the acquisition of spatial contextual cueing. The findings support the reverse hierarchy theory, which predicts that the acquisition of spatial contextual cueing progresses in an easy-to-difficult cascading manner. However, these findings are inconsistent with instance theory, which predicts that the acquisition of spatial contextual cueing in easy-half-repeated trials would keep pace with that in difficult-half-repeated trials. This study concludes that compared with instance theory, reverse hierarchy theory more plausibly explains the acquisition of spatial contextual cueing.
