| Abstract/Results: | ABSTRACT:
OBJECTIVES:
Investigate the mechanism underlying implicit contextual learning and study its neural correlates.
METHODS:
A series of contextual cueing tasks were developed to study different aspects of implicit contextual learning using eye movement recording. Moreover, to define the neural correlates of implicit contextual cueing, several patient and neuroimaging studies were performed.
RESULTS:
We have shown that a snapshot of local contextual information is made using peripheral vision and that different types of contextual information can be used to facilitate visual search through a specific underlying mechanisms. Furthermore, we have demonstrated the importance of the basal ganglia in implicit learning. Finally, distinct neural correlates were found when different types of contextual information were used.
CONCLUSIONS:
Implicit contextual cueing is a complex learning mechanism in which different types of contextual information can be used to facilitate visual search through distinct attention mechanisms. Furthermore, neural correlates of implicit contextual cueing include the basal ganglia, MTL and fronto-parietal networks.
DISCUSSION:
Future research projects should be aimed at further defining the specific role of the basal ganglia and MTL.
