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...

Hearing

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

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.

Summary

This summary is machine-generated.

Children with cochlear implants (CIs) show word learning deficits, particularly in retaining new words. Their word learning abilities are comparable to younger hearing children with similar vocabulary sizes.

Area of Science:

Pediatric audiology
Developmental psychology
Speech and language pathology

Background:

Cochlear implants (CIs) offer auditory input but may impact cognitive processes.
Word learning is crucial for language development in children.

Purpose of the Study:

To investigate word learning challenges in children with CIs.
To assess fast mapping, retention, and extension abilities in pediatric CI users.

Main Methods:

Compared 24 children with CIs to 24 age-matched and 23 vocabulary-matched hearing children.
Assessed novel word learning through comprehension and production measures.
Evaluated word retention and generalization (extension) to new word examples.

Main Results:

Children with CIs exhibited poorer fast mapping and retention compared to age-matched peers.
Hearing peers improved over time, while CI users did not show similar gains.
CI users' performance on word extension was comparable to peers, though some struggled.

Conclusions:

Children with CIs experience significant word learning difficulties, especially with retention.
Word learning in CI users was similar to younger children with comparable vocabulary sizes.
