Impact of Language Experience on Early...
The objective of the study is to longitudinally evaluate the impact of language modality and early language experience on the core numerical representation and on the acquisition of the concept of an exact number. To do this, 180 children aged 3 to 5 will be followed for up to two years.
Leveraging the natural variability occurring within the deaf community, 60 children will be native American Sign Language (ASL) users, 60 children will have been exposed to a visual language after 24 months of age (e.g., deaf children with late cochlear implant and no in-home visual language), and the remaining will be English speaking children with no hearing loss and no delay in language exposure.
Children will be evaluated at ~8 months intervals, between two and four times, on basic number skills until they reach a proficient understanding of the exact number concept. They will also be assessed for language skills and general IQ. Parents will fill out a comprehensive survey on their child’s language use and in-home language.
This paradigm will determine the impact of language modality and proficiency on the developmental trajectory of the core numerical representation. It will also determine if the stages for reaching a full understanding of the exact number concept can be delayed or facilitated depending on language modality.
These long-standing questions in the field of numerical cognition can be uniquely answered through the perspective of a visual language and time of language exposure.
