Supporting older and younger adults' memory for recent everyday events: A prospective sampling study using SenseCam

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Gerontology

Background:

• Memory recall for everyday events can decline with age.
• Wearable technology offers potential tools to aid memory retrieval.
• Understanding how visual cues impact memory is crucial for developing assistive technologies.

Purpose of the Study:

• To evaluate the effectiveness of the SenseCam wearable camera in enhancing memory recall.
• To compare the impact of SenseCam on memory in older versus younger adults.
• To investigate the role of temporal order in SenseCam-assisted memory retrieval.

Main Methods:

• Participants prospectively sampled events using SenseCam over one week.
• Memory recall was assessed two weeks later under three conditions: title only, title with forward-order images, and title with random-order images.
• Episodic and semantic memory recall were measured for both older and younger adults.

Main Results:

• SenseCam significantly increased both episodic and semantic recall in all participants compared to a control condition.
• Older adults showed comparable episodic memory to younger adults when using SenseCam.
• Forward-order SenseCam images showed a slight advantage over random-order images, indicating the importance of temporal sequencing.

Conclusions:

• SenseCam is an effective tool for supporting memory retrieval of recent everyday events across different age groups.
• The temporal order of visual cues plays a role in memory enhancement, suggesting mechanisms related to event sequencing.
• Wearable cameras hold promise for memory augmentation strategies in aging populations and beyond.
