The acquisition of a linguistic skill by adults: Procedural and declarative memory interact in the learning of an artificial morphological rule

摘要: Abstract How does practice make perfect in the acquisition of morphological skill adults? Participants underwent intensive, multi-session training on an artificial rule (AMR) requiring phonological transformations verbs according to a semantic distinction. All participants learned apply AMR repeated items, with power law like improvement speed and accuracy (group average), both within-sessions between-sessions (consolidation phase) gains, robust retention, as non-linguistic learning. Generalization new items evolved separately for different aspects AMR. Phonological were generalized by all participants, independently explicit (declarative) knowledge, well fitted function. However, generalization aspect required discovery its requisite role, was not universally attained; when attained, knowledge coincided abrupt increase initiated phase fluency gains (proceduralization). Our results suggest that procedural declarative memory contribute differentially learning distinct rule, at stages along mastering skilled linguistic performance.
