Social Robots for Evaluating Attention State in Older Adults

Area of Science:

• Cognitive Psychology
• Human-Robot Interaction
• Gerontology

Background:

• Sustained attention is crucial for older adults' independence and preventing health risks like falls.
• Mind-wandering, a decline in attentional focus, is typically reduced in older adults.
• Familiarity with technology can be a barrier for older adults in online studies.

Purpose of the Study:

• To investigate if the age-related reduction in mind-wandering can be observed using a robotic experimenter with older adults.
• To assess the feasibility of using social companion robots for cognitive evaluations in older populations.
• To examine the relationship between attention performance, mind-wandering, and confidence in older adults.

Main Methods:

• A modified Sustained Attention to Response Task (SART) was administered to 28 younger and 22 older adults.
• Participants responded to thought probes about their attention states and provided confidence ratings.
• A robotic experimenter was used to engage participants, particularly older adults less familiar with online technology.

Main Results:

• Older adults exhibited a conservative response strategy, characterized by slower responses and increased omission errors.
• Slower responses and more omission errors were correlated with reduced self-reported mind-wandering.
• These findings align with older adults' higher subjective ratings of attentional control.

Conclusions:

• The study successfully replicated the age-effect on reduced mind-wandering using a robotic experimenter.
• Social companion robots show potential for creating age-specific cognitive profiles for attention evaluation at home.
• This approach may facilitate remote cognitive monitoring and support for older adults.
