Age-Related Changes in Attentional Refocusing during Simulated Driving.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Gerontology

Background:

• Attentional control, particularly refocusing, declines with age.
• This decline may affect real-world tasks like driving.
• Previous research indicated age-related difficulties in switching attention between tasks.

Purpose of the Study:

• To investigate age-related impairments in attentional refocusing within a simulated driving environment.
• To compare performance on single-task versus dual-task (switching) scenarios across different age groups.
• To explore the neural mechanisms underlying age-related attention deficits using electroencephalography (EEG).

Main Methods:

• 118 participants across five age groups (18-91 years) completed a continuous simulated driving task.
• Participants switched attention between braking for traffic and reading road signs.
• EEG data were collected from young (18-30) and older (60+) adults to analyze neural oscillations.

Main Results:

• Significant age-related increases in switch-costs (longer response times) were observed.
• Deficient modulation of theta and alpha brainwave frequencies correlated with age-related attention impairments.
• EEG data revealed age-related changes in neural signatures associated with attentional refocusing.

Conclusions:

• Attentional refocusing difficulties worsen with age, extending to complex, naturalistic tasks like driving.
• Virtual reality (VR) and Neuro-VR offer valuable tools for gerontological and psychological research on aging and cognition.
• Findings underscore the need for strategies to support older drivers' attentional capabilities.
