Do older people know how good they are?

Area of Science:

• Cognitive Psychology
• Neuroscience of Aging

Background:

• Crystallized intelligence remains stable with age, unlike fluid intelligence.
• Metamemory, or knowledge about one's own memory, may be preserved in older adults.

Purpose of the Study:

• To investigate if metamemory accuracy is independent of age-related fluid intelligence decline.
• To assess the relationship between metamemory, fluid intelligence, and self-perception in older adults.

Main Methods:

• 320 participants aged 50-79 predicted performance on memory tasks.
• Predictions were compared to actual task performance.
• Correlations with age, IQ scores, self-ratings, and depression scales were analyzed.

Main Results:

• Actual memory performance correlated with age and IQ, but not self-ratings.
• Prediction accuracy was linked to fluid IQ, self-confidence, and depression scores.
• Higher cognitive test scores predicted more accurate and optimistic self-assessments.

Conclusions:

• Metamemory accuracy is influenced by fluid intelligence and psychological factors like self-regard.
• Age-related changes in fluid IQ and self-perception impact self-assessment accuracy.
• Metamemory is not entirely independent of cognitive aging processes.
