| Research Abstract |
In this project, we aimed to construct the special purpose production system for the psychological studies of musical cognition, and to make use of it for building the simulation model of the human musical cognitive behavior. Followings are the brief description of the results of this project.
(i) Construction of production system. We implemented an experimental adaptive production system - APSH (Adaptive Production System - Hokkaido University) - which has the following facilities;
(1) a module-structured production memory which facilitates the well formed encoding of the hierarchical knowledge structure.
(2) flexible production rules which can add, delete, and change either of production rules in production memory or data elements in working memory.
(ii) Experiments and model building of human melody perception and prediction.
We conducted two experiments to investigate the "final-tone" extrapolating behavior of two music experts, one of Western classic music and the other of Japanese traditional music, for three-note melodies. The experiments verified the schema-driven properties of their perception and prediction of melody. The results indicate that the Westernmusic expert assimilated the stimulus tone sequences to the "diatonic" tonal system of Western music but that the Japanese-music expert did not. The response structures of the Western-music expert were discussed in terms of the processing rules of her tonal schema. We implemented the model of her processing rules on APSH and discussed the psychological validity of the model.
