  • Title: The role of stability in the dynamics of learning, memorizing, and forgetting new coordination patterns.
    Author: Tallet J, Kostrubiec V, Zanone PG.
    Journal: J Mot Behav; 2008 Mar; 40(2):103-16. PubMed ID: 18400677.
    Abstract:
    According to a dynamic theory of learning, how a new memory is formed depends on the stability of the nearest preexisting memories. To predict retention after practice, the authors analyzed how 15 participants memorized 2 bimanual coordination patterns (45 degrees or 135 degrees relative phase). The authors assessed (a) how participants memorized the required patterns with learning and (b) how the associated memory layout evolved. Results showed that a practiced 45 degrees pattern near a very stable memory (0 degrees ) persisted, whereas a 135 degrees pattern near a less stable memory (180 degrees ) was forgotten. Those findings corroborate the proposition that retention of coordination patterns depends on the stability of the extant motor memories. The authors discuss that proposal in terms of the coevolution of accuracy and stability with learning to predict persistence of required or false memories.
