The Relation Between Vocabulary Knowledge and Phonological Awareness in Children With Cochlear Implants
1Davies School of Communication Sciences & Disorders, Texas Christian University, Fort Worth.
Summary
Children with cochlear implants show delays in vocabulary and phonological awareness. However, they utilize lexical information similarly to hearing peers, suggesting potential for targeted interventions.
Area of Science:
- Speech and Hearing Sciences
- Developmental Psychology
- Linguistics
Background:
- Children with cochlear implants (CIs) often experience challenges in language development.
- Lexical knowledge and phonological awareness are crucial for reading acquisition.
- The relationship between these skills in children with CIs requires further investigation.
Purpose of the Study:
- To examine the connection between lexical knowledge and phonological awareness in children with CIs.
- To compare the performance of children with CIs to age-matched and vocabulary-matched children with normal hearing.
- To investigate the role of word neighborhood density in phonological awareness tasks.
Main Methods:
- Thirty children with CIs (5-7 years) and sixty children with normal hearing participated.
- Participants completed a vocabulary knowledge assessment.
- Phonological awareness was evaluated using tasks involving high and low word neighborhood density.
Main Results:
- Children with CIs performed worse than age-matched peers but similarly to vocabulary-matched peers.
- Performance on phonological awareness tasks was influenced by word neighborhood density.
- Vocabulary size significantly correlated with phonological awareness across all groups.
Conclusions:
- Children with CIs exhibit delays in both vocabulary and phonological awareness.
- Children with CIs appear to process lexical information comparable to their hearing peers.
- Findings suggest that lexical information may support phonological awareness development in children with CIs.

01:27Language 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.

01:13The Cochlea
49.8K
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.

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 auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

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...

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...
