The relationship between reasoning and language ability: comparing children with cochlear implants and children with...

Area of Science:

• Cognitive Science
• Developmental Psychology
• Neuroscience

Background:

• Language facilitates complex analogical reasoning.
• Children with cochlear implants (CI) may have language differences impacting cognitive tasks.
• Analogical reasoning is crucial for higher-order thinking.

Purpose of the Study:

• To investigate if language ability explains differences in analogical reasoning between children with CI and typically hearing (TH) children.
• To compare verbal and non-verbal analogical reasoning in children with CI versus two TH groups (age/language matched and age matched).

Main Methods:

• Assessed analogical reasoning (verbal, non-verbal, complex non-verbal) in 15 children with CI (mean age 6;7).
• Compared CI group to 23 age/language matched TH children (TH-A+L, mean age 6;5) and 23 age matched TH children (TH-A, mean age 6;5).

Main Results:

• Children with CI performed similarly to TH-A+L on non-verbal tasks but worse on verbal analogical reasoning.
• Children with CI performed significantly worse than TH-A on complex non-verbal and verbal analogical reasoning tasks.
• A trend difference was observed for simple non-verbal analogical reasoning between CI and TH-A groups.

Conclusions:

• Verbal strategies influence performance on complex non-verbal analogical reasoning tasks.
• Differences in expressive vocabulary may explain performance disparities between children with CI and TH children.
• Language ability is a key factor in analogical reasoning, particularly for complex tasks.
