Assessment of intellectually handicapped adults: a cognitive processing model
Applied Research in Mental Retardation
|January 1, 1982
Summary
This study found that successive processing ability is key for work success in intellectually handicapped adults. This information processing measure is more predictive than IQ tests for vocational training and program planning.
Area of Science:
- Cognitive Psychology
- Intellectual Disability Research
- Vocational Rehabilitation
Background:
- Traditional assessments of intellectual disability often rely on standardized IQ tests.
- Emerging research focuses on information processing measures for a more nuanced understanding of cognitive abilities.
- Work samples are recognized as effective predictors of vocational success.
Purpose of the Study:
- To examine cognitive processing ability, specifically within the information-integration model.
- To investigate the relationship between cognitive processing and performance on work samples.
- To determine the implications for program planning and vocational training for intellectually handicapped adults.
Main Methods:
- Assessed cognitive processing abilities in 50 intellectually handicapped adults.
- Utilized measures based on the information-integration model.
- Correlated processing abilities with performance on validated work samples.
Main Results:
- The study supported the core principles of the information-integration theory in this population.
- Successive processing ability demonstrated a significant relationship with work sample performance.
- Simultaneous processing and planning abilities were less strongly associated with work success.
Conclusions:
- Information-integration theory provides a valid framework for understanding cognitive function in intellectually handicapped individuals.
- Successive processing is a critical factor for predicting vocational success.
- Findings can inform the development of targeted vocational training programs and educational strategies.
