Summary
Newborn hearing screening leads to earlier diagnosis and cochlear implantation for children with severe hearing loss. This early intervention significantly improves spoken language development after cochlear implantation.
Area of Science:
- Pediatric Audiology
- Developmental Pediatrics
- Speech-Language Pathology
Background:
- Early detection of hearing loss is crucial for optimal child development.
- Newborn hearing screening programs aim to identify infants with hearing impairments shortly after birth.
- Delayed diagnosis and intervention can negatively impact spoken language acquisition.
Purpose of the Study:
- To evaluate the impact of newborn hearing screening on the timing of diagnosis and cochlear implantation.
- To assess the effect of early screening on spoken language development in severely hearing-impaired children.
- To compare language outcomes between early and late screened children post-cochlear implantation.
Main Methods:
- Retrospective analysis of severely hearing-impaired children divided into early (n=149) and late (n=139) screened groups.
- Evaluation of age at diagnosis and age at cochlear implantation.
- Quantification of spoken language development using language quotients (LQs) at 1, 2, and 3 years post-implantation.
Main Results:
- Children identified through early screening were significantly younger at diagnosis and cochlear implantation.
- Early screening was associated with enhanced receptive and expressive spoken language skills.
- A positive correlation was observed between early intervention and improved language outcomes.
Conclusions:
- Newborn hearing screening facilitates earlier intervention for infants with hearing loss.
- Early identification and cochlear implantation positively influence spoken language development.
- The implemented screening programs effectively improved developmental trajectories for deaf children.

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 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.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
