Memory in learning disabled children: digit span and the Rey Auditory Verbal Learning Test
1Cobb County Public Schools, Marietta, GA, USA.
Summary
Digit span tests are insufficient for diagnosing auditory memory issues in learning disabled students. Rey Auditory Verbal Learning Test (RAVLT) scores showed no significant relationship with digit span measures in this study.
Area of Science:
- Neuropsychology
- Educational Psychology
Background:
- Learning disabilities often involve auditory processing and memory deficits.
- Accurate assessment of auditory memory is crucial for effective intervention.
Purpose of the Study:
- To investigate the relationship between Rey Auditory Verbal Learning Test (RAVLT) performance and WISC-R digit span in learning disabled students.
- To determine if digit span is a reliable indicator of auditory memory functioning in this population.
Main Methods:
- Compared RAVLT scores with WISC-R forward and backward digit span in 153 learning disabled students.
- Utilized regression analyses controlling for age and IQ.
- Performed factor analysis on memory test variables.
Main Results:
- No significant relationships were found between RAVLT scores and any digit span measures (forward, backward, total).
- Factor analysis identified distinct memory components: long-term memory, and short-term memory with high/low coding demands.
- Digit span did not adequately capture the nuances of auditory memory assessed by the RAVLT.
Conclusions:
- Digit span alone is inadequate for diagnosing auditory memory deficits in learning disabled students.
- Auditory memory functioning is complex and not fully represented by simple digit span tasks.
- Relying solely on digit span may lead to misdiagnosis and inappropriate educational planning.
