[Contextual control in teaching numbers to a child with intellectual disability]

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Behavioral Analysis

Background:

• Individuals with intellectual disabilities often face challenges in abstract concept learning.
• Understanding number concepts like 'equal' and 'different' is foundational for mathematical skills.
• Contextual control is a key principle in analyzing and teaching complex discriminations.

Purpose of the Study:

• To teach a seven-year-old child with intellectual disability to discriminate between 'equal' and 'different' numerical concepts.
• To investigate the effectiveness of second-order conditional discrimination in teaching number relations.
• To assess the transfer of learned discrimination skills to novel numerical stimuli.

Main Methods:

• A second-order conditional discrimination procedure was implemented.
• The participant was trained to select specific number comparisons based on sample stimuli and contextual cues ('equal' or 'different').
• Generalization was tested by introducing new number sets (three and four) without explicit training.

Main Results:

• The child successfully learned the 'equal' and 'different' number discriminations with the initial set of numbers (one and two).
• The participant demonstrated learning transfer, correctly applying the discrimination rules to the novel number sets (three and four).
• No explicit training was required for the transfer to the new numbers, indicating robust learning.

Conclusions:

• Second-order conditional discrimination is an effective method for teaching abstract numerical concepts to individuals with intellectual disabilities.
• Learned number discriminations can generalize to untrained stimuli, suggesting the development of a generalized concept.
• This approach holds promise for improving mathematical foundational skills in children with intellectual disabilities.
