Language Development

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Higher Mental Functions of the Brain: Language

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Summary

Cochlear implants improve hearing in deaf children, but language skills vary significantly. This variability may stem from factors beyond auditory thresholds, possibly involving the child's linguistic brain development.

Area of Science:

Neuroscience
Genetics
Audiology

Background:

Cochlear implants significantly enhance sensory perception in deaf children.
However, considerable variability exists in language proficiency among children with cochlear implants.

Observation:

This case series examined language acquisition in four prelingually deaf children with GJB2 gene mutation Cx26-related deafness.
Despite similar clinical histories and good post-implant audiometry, two children showed poor speech audiometry results, while two performed well.

Findings:

Language impairment in some cochlear-implant recipients may not solely depend on auditory thresholds.
This suggests potential underlying damage to the brain's linguistic processing centers.

Implications:

Further research is needed to understand the neurological factors influencing language outcomes in implanted children.
This may lead to more personalized interventions for congenital deafness.
