Autistic children understand cardinality similarly to peers but struggle with conservation tasks and counting strategies. Targeted interventions may improve foundational numerical skills in autistic children.
Area of Science:
- Developmental Psychology
- Autism Spectrum Disorder Research
- Cognitive Science
Background:
- Understanding numerical concepts like cardinality and conservation is crucial for mathematical development.
- Autism Spectrum Disorder (ASD) can impact cognitive processing, potentially affecting numerical understanding.
- Previous research has explored numerical cognition in autistic individuals, but specific strategy use requires further investigation.
Purpose of the Study:
- To compare cardinality and conservation understanding in autistic and non-autistic children (aged 4-7 years).
- To investigate the relationship between counting strategies and numerical understanding in these groups.
- To identify potential areas for intervention to support mathematical development in autistic children.
Main Methods:
- Study included 82 children (41 autistic, 41 neurotypical), aged 4-7 years, without intellectual disability.
- Participants completed tasks assessing cardinality, conservation, and counting strategies (verbal counting with pointing [VCP], rapid recognition [N]).
- Response times during counting tasks were recorded.
Main Results:
- Both groups showed similar cardinality understanding.
- Autistic children performed significantly lower on conservation tasks and had longer counting response times.
- Autistic children favored VCP and used the N strategy less, even for small sets; N strategy linked to conservation.
Conclusions:
- Autistic children may face relative difficulties in conservation and specific counting strategy use.
- Foundational numerical skills, particularly conservation, may benefit from targeted interventions.
- Supporting diverse counting strategies could enhance mathematical development in autistic children.
