Summary
The SON-R 5 1/2-17, a non-verbal intelligence test, is feasible for assessing fluid intelligence in older adults. Further research is needed to develop adult norms for this user-friendly tool.
Area of Science:
- Neuropsychology
- Gerontology
- Psychometrics
Background:
- The SON-R 5 1/2-17 is a non-verbal intelligence test designed for deaf children.
- Its potential utility in assessing older adults, including neurological patients, warrants investigation.
Purpose of the Study:
- To evaluate the feasibility and validity of the SON-R 5 1/2-17 in a healthy elderly population.
- To explore its suitability for future use with older neurological patients.
Main Methods:
- Investigated 58 healthy elderly individuals.
- Administered the SON-R 5 1/2-17, Raven Progressive Matrices, and a Dutch reading test.
- Collected subjective user feedback on the tests.
Main Results:
- The SON-R 5 1/2-17 demonstrated user-friendliness.
- High correlations between subtests and with other intelligence measures suggest SON-R validity for fluid intelligence in the elderly.
- Existing norms are unsuitable for adult populations.
Conclusions:
- The SON-R 5 1/2-17 is a valid and user-friendly tool for measuring fluid intelligence in older adults.
- Development of specific adult norms is crucial for accurate assessment.
- The test shows promise for application in older neurological patients.
