Document Summary
Statistical learning is an automatic acquisition or inference about the statistical properties of a stream of items. Domain-general learning mechanism: applies across both various types of stimuli (verbal/nonverbal) Important for language acquisition: 8 month old infants can learn statistical properties of stream of verbal info. Phase 1: view a continuous stream of shapes for 5-10 minutes. Phase 2: forced choice recognition test (did you see option a or b?). Experiment uses stimuli from fiser and aslin and a method based on turk-brown et al. to illustrate statistical learning. Stream was made up of four triplets (triplet is three shapes that always occurred in same order). Each triplet preceded and followed every other triplet equally often. At test, 2 triplets were shown, indicate which was more familiar. Always: three shapes that always appeared in succession (abc) Impossible: made up of three shapes never appearing in succession (adg)
