Summary
Cochlear implants (CI) significantly improve auditory and language skills in prelingual deaf children. Early implantation and higher socioeconomic status are key factors for better outcomes in Mandarin-speaking children.
Area of Science:
- Pediatric Audiology
- Speech-Language Pathology
- Otolaryngology
Background:
- Prelingual deafness impacts auditory, speech, and language development.
- Cochlear implantation (CI) is a primary intervention for pediatric hearing loss.
- Understanding early outcomes in diverse linguistic populations is crucial.
Purpose of the Study:
- To assess early auditory, speech perception, and language skills in Mandarin-speaking children post-CI.
- To identify factors influencing auditory and language development after cochlear implantation.
- To analyze outcomes within the first two years following CI surgery.
Main Methods:
- Longitudinal study of 132 Mandarin-speaking children pre- and post-CI.
- Utilized standardized assessments: ITMAIS/MAIS, MESP, and PCDI.
- Evaluated auditory integration, speech perception, and language development.
Main Results:
- CI recipients showed developmental trajectories similar to normal-hearing peers.
- Significant improvements in speech perception (MESP categories) were observed.
- Age at implantation and socioeconomic status correlated with auditory and language gains.
Conclusions:
- Mandarin-speaking children demonstrate substantial auditory and language progress with CI.
- While following normative paths, a developmental gap persists.
- Earlier CI and higher socioeconomic status predict enhanced early auditory and language skills.

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 is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.

01:24Components of Language

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

01:27Language and Cognition
813
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.

01:11The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

01:17Auditory Perception

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...
