Extraversion, activation and the recall of prose
British Journal of Psychology (London, England : 1953)

Summary
Moderate arousal levels enhance memory recall. This study found that individuals with moderate activation, specifically high activation extraverts and low activation introverts, made fewer errors and recalled more information accurately.
Area of Science:
- Cognitive Psychology
- Personality Psychology
Background:
- Individual differences in personality, such as extraversion, influence cognitive processes.
- Arousal levels are known to impact performance on various tasks, including memory.
Purpose of the Study:
- To investigate the interactive effects of personality (extraversion) and arousal (activation) on memory recall performance.
- To determine optimal arousal levels for accurate information retrieval.
Main Methods:
- Participants were categorized into four groups based on Eysenck Personality Inventory (EPI) extraversion scores and Thayer's Activation-Deactivation Adjective Check List (ADACL) activation scores.
- Subjects were tasked with recalling a prose passage under error-avoidance instructions.
Main Results:
- Significant interactions were observed between activation and extraversion for both error rates and correctly recalled phrases.
- Optimal recall performance (fewest errors, most correct phrases) was associated with moderate arousal levels: high activation in extraverts and low activation in introverts.
Conclusions:
- Arousal plays a critical role in memory recall.
- The findings suggest that arousal influences memory retrieval processes, with specific optimal levels depending on personality traits.
