The effect of figure - ground segregation on visual search and implicit learning

E Kim, J Lee, W Jung

Three experiments were conducted to investigate the effect of the difficulty of figure - ground segregation on implicit learning of the task-irrelevant background and on visual search. In all experiments, contextual cueing paradigm was used and the difficulty of figure - ground segregation was defined by similarity of features between background and search items. The results of experiment 1 showed that repeated background helped search target, indicating that the background was implicitly learned. As similarity of features increased, the implicit learning of background became stronger. Experiment 2 was performed with the figure and background separated by binocular depth cue. The implicit learning of the background also occurred when the background was repeatedly presented and a feature of the background was similar to one of the search items, whereas when it was dissimilar implicit learning became weaker. In experiment 3, with random dots, implicit learning of the background disappeared, indicating that the background without form information could not be learned implicitly. These results mean that task-irrelevant background can be learned implicitly, and figure - ground segregation has an important role in visual search and implicit learning.[This research was supported as a Brain Neuroinformatics Research
