Summary
Cochlear implants significantly improved language skills in deaf children. Children using the CLARION device showed faster language growth than hearing peers, regardless of communication method.
Area of Science:
- Pediatric Audiology
- Developmental Linguistics
- Speech-Language Pathology
Background:
- Prelingually deaf children face significant language development challenges.
- Cochlear implantation is a key intervention for profound hearing loss.
- The CLARION Multi-Strategy Cochlear Implant offers a novel approach to auditory rehabilitation.
Purpose of the Study:
- To evaluate the impact of the CLARION cochlear implant on language development in prelingually deaf children.
- To compare language skill progression in the initial 6 months post-implantation.
- To assess the influence of communication modality (oral vs. total communication) on language outcomes.
Main Methods:
- Longitudinal study involving 23 prelingually, profoundly deaf children.
- Preoperative and 6-month postoperative assessment of language skills using the Reynell Developmental Language Scales (RDLS).
- Evaluation across preferred communication modes: spoken English or simultaneous spoken and signed English.
Main Results:
- Significant improvements in both receptive and expressive language skills were observed post-implantation.
- Implanted children demonstrated a language growth rate exceeding that of normal-hearing children matched for language age.
- No significant difference in language performance was found between children using oral communication versus total communication.
Conclusions:
- The CLARION cochlear implant facilitates substantial language development in prelingually deaf children.
- Children implanted with CLARION show accelerated language acquisition post-surgery.
- Communication modality does not appear to be a significant factor in early language outcomes with this device.

Hearing
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.
The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
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...

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 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.
