Age-related decline in perception of prosodic affect

Area of Science:

• Neuropsychology
• Psycholinguistics
• Cognitive Aging

Background:

• Affect perception in speech is crucial for understanding speaker intent, often exceeding semantic meaning.
• Right-hemisphere lesions can impair affect perception, yet emotional prosody is under-explored in clinical neuropsychology.
• Emotional prosody perception is vital for social communication and understanding emotional nuances in spoken language.

Purpose of the Study:

• To present data from a revised Emotional Perception Test (EPT-R).
• To investigate age-related differences in the perception of emotional prosody.
• To compare the magnitude of age-related prosodic perception deficits with other cognitive functions.

Main Methods:

• Utilized a revised Emotional Perception Test (EPT-R) to assess emotional prosody perception.
• Compared performance between IQ-matched younger and older adult participants.
• Analyzed differences in prosodic perception abilities across age groups.

Main Results:

• Older participants performed significantly worse on prosodic perception tasks than younger participants.
• Age-related deficits in emotional prosody perception were observed.
• The magnitude of these age-related differences was comparable to those found in memory tests.

Conclusions:

• The revised Emotional Perception Test (EPT-R) highlights significant age-related decline in emotional prosody perception.
• These findings underscore the importance of considering emotional prosody in clinical neuropsychology, particularly in aging populations.
• The observed decline in prosodic perception parallels memory impairments, suggesting broader cognitive aging effects.
