Outline of Annual Research Achievements

2021年度は、研究項目1、2、3について研究を進めた。
1. 共想法に立脚した共創的コミュニケーション支援技術のランダム化対照群つき比較試験データの解析:試験終了後の介入群、対照群の頭部MRI画像を、脳の状態を調べる代表的な3通りの方法(安静時機能的結合resfMRI、局所脳体積VBM、白質線維経路DTI)で撮像したものを解析し、関連する脳の領域間のつながりがよくなり、関連する脳の領域の体積が増加する可能性が示された。
2. 社会性と相関のある認知機能、脳機能および構造の解明:高齢者の社会的比較志向性が認知や脳の状態とどのように関連しているかを明らかにした。社会的比較志向性とは、自己と他者を比較する心理傾向のことを指し、それには「意見」と「能力」の二つの次元があるとされている。これら二つの次元についての主観的な度合いと、認知機能検査のスコアおよびMRI検査で測られる脳の様々な指標との間の関係を調べた結果、「意見」を比較する傾向が強い高齢者ほど、認知機能検査のスコアが高く、海馬と呼ばれる脳領域の体積が大きく、安静時の機能的結合が強く、白質繊維連絡の拡散異方性が高いことが分かった。一方で、「能力」を比較する傾向の強さとの間には、これらのような関係は見られなかった。
3. 言語特徴量と相関のある認知機能、脳機能および構造の解明:話し言葉における語彙の豊かさと関連する脳の状態を明らかにした。語彙の豊かさを表す指標としてHeaps’ lawと呼ばれるスケーリング則の指数であるβを用い、高齢者のグループ会話の録音データを基に個人のβの値を算出し、βとMRI検査で測られる脳の様々な指標との間の関係を調べたところ、βの値が高い人ほど、意味処理に関連する左中側頭回前部の体積が大きく、この領域とデフォルト・モード・ネットワークのコア領域である楔前部の安静時の機能的結合が弱いことが分かった。
