Summary
Normal aging negatively impacts confrontational naming ability. Older adults showed lower accuracy and slower response times on the Chinese Naming Test compared to younger adults.
Area of Science:
- Neuroscience
- Psychology
- Linguistics
Background:
- Confrontational naming ability changes with normal aging.
- Previous studies reported inconsistent findings on this topic.
- Accurate assessment requires considering both accuracy and response latency.
Purpose of the Study:
- To reexamine the effect of normal aging on confrontational naming.
- To investigate age-related differences in naming accuracy and response latency.
- To clarify the impact of aging on confrontational naming in Cantonese-speaking Chinese.
Main Methods:
- Study included 60 healthy Cantonese-speaking Chinese adults.
- Participants were divided into a Young Age Group (n=30) and an Old Age Group (n=30).
- The Chinese Naming Test (CNT) was used to measure confrontational naming ability.
Main Results:
- Younger adults significantly outperformed older adults in naming accuracy.
- Older adults exhibited slower response latencies compared to younger adults.
- Performance differences were not attributable to variations in educational attainment or gender.
Conclusions:
- Normal aging has a detrimental effect on confrontational naming.
- Age-related decline in naming ability is evident in both accuracy and speed.
- The observed decline in naming ability with aging is likely multifactorial.
