Differences in autobiographical memories reported using text and voice during everyday life.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• Autobiographical memory research often uses diary methods for ecological validity.
• Laboratory studies typically involve spoken recall of memories.
• Direct comparisons of typing versus spoken recall in real-world settings are limited.

Purpose of the Study:

• To directly compare autobiographical memories recorded via typing versus oral recording.
• To investigate differences in memory reporting frequency, promptness, and content.
• To inform methodological choices in autobiographical memory research.

Main Methods:

• A four-day smartphone diary study comparing two groups: typing autobiographical memories (n=43) and orally recording them (n=39).
• Participants reported memories as they occurred in daily life.
• Data analyzed for reporting frequency, promptness, word count, and episodic/perceptual detail.

Main Results:

• The audio recording group reported memories more frequently and with more words.
• The typing group reported memories more promptly after occurrence.
• Typing resulted in richer episodic details and a higher proportion of perceptual details.

Conclusions:

• The modality of reporting (typing vs. speaking) influences autobiographical memory characteristics.
• Audio recording may capture more frequent and voluminous memory recall.
• Typing may enhance the richness and detail of recalled episodic memories.
• Methodological choices in memory research should align with specific research objectives.
