Stimulus selection by the retarded: list length and response requirement
The American Journal of Psychology
|March 1, 1975
Summary
Institutionalized individuals with intellectual disabilities improved cue selection efficiency in memory tasks as information load increased. They adapted by using strategies that reduced memory demands when faced with complex paired-associate learning.
Area of Science:
- Cognitive Psychology
- Developmental Psychology
- Neuroscience
Background:
- Individuals with intellectual disabilities often exhibit challenges in memory and information processing.
- Understanding adaptive strategies in this population is crucial for developing effective interventions.
Purpose of the Study:
- To investigate stimulus selection and memory strategies in institutionalized individuals with intellectual disabilities.
- To determine if participants could adapt their processing strategies based on task demands.
Main Methods:
- Paired-associate learning using redundant trigrams and double digits.
- Manipulation of list length (four or six items) and response requirements (recall or recognition).
- Transfer test to assess stimulus selection efficiency.
Main Results:
- Participants demonstrated increased efficiency in cue selection as the amount of information in the paired-associate task increased.
- This suggests an active adaptation of cognitive strategies to manage memory load.
Conclusions:
- Institutionalized individuals with intellectual disabilities can develop and employ adaptive memory strategies.
- Findings indicate a capacity for metacognitive control, adjusting processing to minimize memory load under increased task complexity.
