Summary
Patients with stroke show poorer prospective memory (PM) performance than controls, but do not report more PM failures. This dissociation highlights the need for comprehensive PM assessments in stroke patients.
Area of Science:
- Neuroscience
- Cognitive Psychology
Background:
- Prospective memory (PM) is crucial for daily activities.
- PM deficits are common in stroke survivors, impacting quality of life.
- Understanding PM in stroke requires evaluating both performance and self-perception.
Purpose of the Study:
- To compare prospective memory failures between stroke patients and healthy controls.
- To investigate discrepancies between objective PM performance and subjective self-assessment.
- To explore the implications of metacognitive awareness in stroke-related PM deficits.
Main Methods:
- Thirty-five stroke patients and forty healthy controls participated.
- Participants completed the Prospective scale of the Prospective and Retrospective Memory Questionnaire (PRMQ).
- The event-based task of the Miami Prospective Memory Test (MPMTevent) was administered.
Main Results:
- Stroke patients demonstrated significantly impaired performance on the MPMTevent compared to controls.
- No significant differences in PRMQ scores were found between stroke patients and controls.
- Stroke patients underestimated their PM deficits compared to objective performance.
Conclusions:
- A dissociation exists between objective PM performance and self-reported awareness in stroke patients.
- Reduced metacognitive awareness may impede stroke survivors' ability to implement compensatory strategies.
- Comprehensive PM assessment should integrate performance-based tasks and self-report measures for stroke patients.

03:00Self-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...
02:05Self-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...
01:22Self-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.
01:29Self-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...
01:29Introspection
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...
01:24Sources 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,...
