Outline of Final Research Achievements	The contrast between the unidirectional and bidirectional flow of the auditory information was tested in the yoked-control design. The participants of both groups were required to clap their hands in time to the same piano performance. While the pianist received the feedback sounds of the hand clapping of the bidirectional group, the pianist did not receive those of the unidirectional group. The onset time of each beat was estimated by a signal processing to the digital recordings of the piano sounds and those of clap sounds. The result revealed higher synchronization indices for the bidirectional condition than for the unidirectional condition. The cross-correlations made an analysis of inter-beat interval of each the performance and hand clapping. The result revealed that the performer and the audience for the bidirectional condition tried to match by mutually using the beat of the past beats.
Free Research Field	音楽心理学、音楽教育学
Academic Significance and Societal Importance of the Research Achievements	学術的意義の１点目は、聴覚フィードバックという演奏と聴衆の相互作用を生じさせる要因から科学的に証明した点にある。2点目は演奏と手拍子の拍時点を音響解析から推定したことにある。MIDIで取得できない楽器など多様な演奏場面へ拡張可能となる。3点目は演奏と聴衆の相互作用を、聴取中の経時的変化から分析し、動的な様相を捉えられたことにある。このほかに、演奏者と聴衆の相互作用は演奏や鑑賞の質に影響し、本研究の成果は演奏場面や音楽教育へ汎用できる点に社会的意義が認められる。
