The Impacts of Aging on Affective Prosody Comprehension: A Comparative Study.

Area of Science:

• Psychology
• Neuroscience
• Linguistics

Background:

• Affective prosody comprehension, the ability to understand emotions in speech, declines with healthy aging.
• This ability relies on perceptual, lexical, and semantic cognitive components.
• The specific cognitive components and psycholinguistic variables affected by aging remain unclear.

Purpose of the Study:

• To investigate the impact of aging on affective prosody comprehension.
• To explore the relationship between aging, underlying cognitive components, and psycholinguistic variables.
• To determine how emotion category, valence, and arousal influence age-related changes in emotion recognition from speech.

Main Methods:

• Recruited 60 healthy adults (30 younger, 30 older).
• Administered a general affective prosody comprehension task.
• Assessed perceptual, lexical, and semantic cognitive components through specific tasks.

Main Results:

• Older adults demonstrated reduced performance in general affective prosody comprehension compared to younger adults.
• Lexical abilities were specifically impacted in older adults.
• Psycholinguistic variables, including emotion category and arousal, influenced the decreased performance observed in older adults.

Conclusions:

• Aging significantly affects affective prosody comprehension, with a notable decline in lexical processing.
• Understanding the role of psycholinguistic variables is crucial for comprehending age-related changes in emotion recognition from speech.
• These findings advance the understanding of normal aging processes in affective prosody comprehension.
