Modifiability of fluid intelligence in aging: a short-term longitudinal training approach
Journal of Gerontology
|March 1, 1978
Summary
Cognitive training can enhance fluid intelligence in older adults. This study shows that targeted interventions can improve cognitive abilities, suggesting intellectual performance is modifiable with age.
Area of Science:
- Cognitive Neuroscience
- Gerontology
- Psychology
Background:
- Fluid intelligence, a key cognitive ability, often declines with age.
- Previous research suggested limited plasticity of cognitive functions in older adults.
Purpose of the Study:
- To assess the modifiability of fluid intelligence in aged individuals.
- To evaluate the effectiveness of a cognitive training program targeting Figural Relations.
Main Methods:
- 15 experimental and 15 control subjects (mean age 69) participated.
- A cognitive training program focused on fluid intelligence (Figural Relations).
- Post-training assessments included near (fluid intelligence) and far (crystallized intelligence) transfer measures at 1 week, 1 month, and 6 months.
Main Results:
- The training program successfully enhanced performance on the nearest fluid intelligence measure across all posttests.
- Improvements were also observed for a near fluid intelligence measure at the first posttest.
- General retest effects, possibly due to test sophistication, were noted but were not hierarchically ordered.
Conclusions:
- Cognitive training can significantly improve specific components of fluid intelligence in older adults.
- Intellectual performance in old age demonstrates greater modifiability through behavioral interventions than previously assumed.
- Findings support the potential for targeted cognitive interventions to enhance cognitive function in aging populations.
