まとめ
脳卒中患者は、対照群と比較して見込み記憶(PM)のパフォーマンスが低いことを示していますが、PM障害の報告は多くありません。この乖離は、脳卒中患者における包括的なPM評価の必要性を強調しています。
科学分野:
- 神経科学
- 認知心理学
背景:
- 見込み記憶(PM)は、日常生活活動にとって非常に重要です。
- PMの障害は脳卒中生存者によく見られ、生活の質に影響を与えます。
- 脳卒中におけるPMの理解には、パフォーマンスと自己認識の両方の評価が必要です。
研究 の 目的:
- 脳卒中患者と健康な対照群の間で見込み記憶障害を比較すること。
- 客観的なPMパフォーマンスと主観的な自己評価との間の不一致を調査すること。
- 脳卒中関連のPM障害におけるメタ認知意識の含意を探求すること。
主な方法:
- 35人の脳卒中患者と40人の健康な対照群が参加しました。
- 参加者は、見込み記憶および回顧記憶質問票(PRMQ)の見込み記憶尺度を完了しました。
- マイアミ見込み記憶テスト(MPMTevent)のイベントベースタスクが管理されました。
主要な成果:
- 脳卒中患者は、対照群と比較してMPMTeventで有意に低下したパフォーマンスを示しました。
- 脳卒中患者と対照群の間でPRMQスコアに有意な差は見られませんでした。
- 脳卒中患者は、客観的なパフォーマンスと比較してPM障害を過小評価していました。
結論:
- 脳卒中患者における客観的なPMパフォーマンスと自己報告された認識との間には乖離が存在します。
- メタ認知意識の低下は、脳卒中生存者が代償戦略を実施する能力を妨げる可能性があります。
- 包括的なPM評価には、脳卒中患者のパフォーマンスベースのタスクと自己報告測定値を統合する必要があります。

Self-Evaluation: Self-Enhancement and Self-Verification
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
Self-Presentation: Self-Monitoring and Self-Handicapping
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
Self-Evaluation Maintenance Model
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
Introspection
Introspection, long upheld as a reliable route to self-knowledge, involves examining one's thoughts, emotions, and mental processes. It underpins many psychological practices, from mindfulness meditation to psychotherapy and self-help strategies. However, empirical evidence challenges the accuracy of introspection as a means of understanding oneself.Limitations of Introspective InsightSeminal work by Nisbett and Wilson demonstrated that individuals are frequently unaware of the true causes...
Sources of Self-Esteem II: Performance Feedback
Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem: self-efficacy,...
