Learning sequential structures is of fundamental importance for a wide variety of human skills. While it has long been debated whether implicit sequence learning is perceptual or response-based, here we propose an alternative framework that cuts across this dichotomy and assumes that sequence learning rests on associative changes that can occur…

The present article attempts to discover if learners can use three higher order transitions between subunits- to extend structures made of right-branching trees, to elaborate a tree by adding substructures, alternating responses from the two subsystems. (Author)
