まとめ
高齢者は報酬を失うことを避けるために多くの努力を払い、若者は報酬を得るために多くの努力を払った。努力の支出は気分や意欲とは相関しなかった。
科学分野:
- 認知心理学
- 神経科学
- 行動経済学
背景:
- 努力ベースの意思決定は、目標指向行動に不可欠である。
- 選択の年齢とフレーミング(リスク対報酬)は、努力の配分に影響を与える可能性がある。
主な方法:
- 修正版努力支出報酬タスク(M-EEfRT)を若年成人(YA)と高齢者(OA)に実施した。
- 参加者は気分(PANAS)と意欲(DAS)の質問票に回答した。
結論:
- 努力の支出に対するフレーミング効果は、年齢層によって異なる。
- 客観的なパフォーマンス指標は、主観的な自己申告とは相関しなかった。
- 今後の研究では、代替タスク検証方法を検討する。
