How Age and Linguistic Competence Affect Memory for Heard Information

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Auditory Perception

Background:

• Older first language (EL1) adults exhibit poorer memory than younger EL1 adults in paired-associate tasks.
• Second language (EL2) listeners may have less developed semantic and linguistic skills.
• Previous research indicates age-related memory decline may stem from higher-order cognitive processes.

Purpose of the Study:

• To compare short-term memory performance in young English as a second language (EL2) listeners versus younger and older English as a first language (EL1) listeners.
• To investigate if less developed EL2 semantic and linguistic skills lead to memory deficits.
• To determine if memory performance differences persist after equating for word recognition across groups.

Main Methods:

• Participants included young EL2 listeners, young EL1 listeners, and older EL1 listeners.
• A paired-associate memory task was administered in quiet and noisy conditions.
• Auditory noise levels were adjusted to equalize word recognition across all listener groups.

Main Results:

• No significant memory performance differences were observed between young EL1 and young EL2 listeners.
• Equating word recognition eliminated memory deficits in young EL2 listeners compared to young EL1 listeners.
• Findings suggest that semantic and linguistic skill differences had minimal impact on paired-associate recall.

Conclusions:

• Age-related memory decline may be linked to declines in higher-order processes like stream segregation and episodic memory.
• The cognitive load on memory processes might increase due to age-related declines.
• The study provides insights into spoken language comprehension challenges for different listener groups.
