Rapid alternating stimulus naming in the developmental dyslexias.
Brain and Language
|March 1, 1986
Summary
This study shows that rapid, alternating stimulus (RAS) naming performance in kindergarten predicts later reading ability in children. Early RAS results help identify reading impairments and reading subgroups.
Area of Science:
- Cognitive Psychology
- Developmental Psychology
- Educational Psychology
Background:
- Dyslexic readers often struggle with rapid serial naming tasks, which involve directing attention to contextual patterns.
- The development of automaticity in reading is crucial for fluent word recognition.
Purpose of the Study:
- To investigate the developing ability of dyslexic readers to attend to contextual patterns during rapid serial naming.
- To determine the predictive validity of rapid, alternating stimulus (RAS) naming for later reading abilities.
Main Methods:
- A 3-year longitudinal study involving 98 children.
- Development and application of a rapid, alternating stimulus (RAS) naming measure.
- Analysis of RAS performance to differentiate reading abilities and identify dyslexic subgroups.
Main Results:
- RAS performances effectively distinguished between average and impaired readers.
- Distinct dyslexic subgroups were identified based on RAS performance, with some unable to complete tasks in kindergarten.
- Early RAS performance strongly predicted later single-word reading levels.
Conclusions:
- RAS naming is a valuable tool for assessing attentional and retrieval speed in reading development.
- Early identification of reading difficulties using RAS measures can inform targeted interventions.
- The findings highlight the critical link between retrieval speed, automaticity, and reading proficiency in dyslexia.
