Contingency learning in 9-month-old infants with Down syndrome
Insights
Infants with Down syndrome showed difficulty learning a contingency task compared to typically developing infants. Some infants with Down syndrome mastered the task, correlating with mental development scores.
Area of Science:
- Developmental Psychology
- Pediatrics
- Genetics
Background:
- Infants' ability to learn cause-and-effect (contingency learning) is crucial for development.
- Down syndrome is associated with cognitive and developmental challenges.
- Understanding learning in infants with Down syndrome informs early intervention strategies.
Purpose of the Study:
- To assess the contingency learning abilities of 9-month-old infants with Down syndrome.
- To compare their learning to infants without disabilities.
- To explore the relationship between learning and cognitive development in infants with Down syndrome.
Main Methods:
- Ten 9-month-old infants with Down syndrome and a control group of infants without disabilities participated.
- Arm movements were reinforced with auditory and visual stimuli to teach a contingency.
- The Bayley Scales of Infant Development were used to assess mental development.
Main Results:
- Infants with Down syndrome, as a group, did not learn the contingency as effectively as the control group.
- Individual performance varied, with some infants with Down syndrome successfully mastering the task.
- Contingency learning performance was related to scores on the Mental Development Index.
Conclusions:
- Some infants with Down syndrome may face challenges in conditionability, potentially declining with age.
- Conditionability appears linked to overall mental development in infants with Down syndrome.
- These findings highlight the heterogeneity within the Down syndrome population regarding learning abilities.
Abstract:
The ability of ten 9-month-old infants with Down syndrome to acquire a contingency in which arm movements were reinforced with auditory and visual stimulation was assessed. Unlike a group of infants without identifiable disabilities, those with Down syndrome did not learn the contingency. Examination of the performance of individual infants with Down syndrome indicated that some infants did master the contingency. In addition, there was a relation between contingency performance and scores on the Mental Development Index of the Bayley Scales of Infant Development. Results were discussed in terms of the possibility that some infants with Down syndrome experience a decline in conditionability with age and the relation between conditionability and mental development.

Cognitive Learning
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
