Black-white differences in memory test performance among children and adolescents.
1Texas A&M University and Meyer Rehabilitation Institute, College Station 77843-4225, USA.
Summary
This study found minimal racial differences in short-term memory performance among children and adolescents. Unlike other cognitive tests, race had little impact on most memory measures examined.
Area of Science:
- Neuropsychology
- Cognitive Psychology
- Individual Differences
Background:
- Racial disparities in mental test scores are well-documented.
- Neuropsychologists have recently begun examining demographic factors in test performance.
- Short-term memory has not been extensively studied in this context.
Purpose of the Study:
- To investigate racial differences in short-term memory performance.
- To analyze performance on 14 distinct short-term memory measures.
- To compare findings with typical results from intellectual aptitude tests.
Main Methods:
- A nationally stratified, population-proportionate sampling plan was used.
- 168 Black and 983 White children and adolescents (ages 5–19) were tested.
- Age-corrected deviation scaled scores were calculated using rolling weighted averages.
Main Results:
- Only one significant racial difference was observed across 14 memory measures.
- This contrasts sharply with findings for intellectual and other aptitude measures.
- Most short-term memory tests showed no significant performance differences between racial groups.
Conclusions:
- Racial group differences in short-term memory appear minimal.
- Neuropsychological test performance may vary significantly across different cognitive domains.
- Further research is needed to understand the nuances of demographic influences on memory.
