Hearing loss in childhood and infancy can have a major effect on the development and continuation of language. It hinders the acoustic signal that enters the ear canal to not be fully received by the auditory cortex which then affects and distorts what we receive and how we comprehend the auditory stimuli. There are different types and degrees of severity of hearing loss that can impair one or both ears, or can be congenital. Children with a hearing loss that is either severe or profound, in both ears, sensory neural, or congenital are considered to be a candidate for a cochlear implant. Cochlear implants are the only way for these children to develop oral language and auditory skills when hearing aids are not beneficial (Jimenez-Romero, 2015). …show more content…

They compared whether children with cochlear implants, children the same age with normal hearing, and children with the same vocabularies could fast map, retain, and extend new words while being shown their “unfamiliar object referents” (Walker and McGregor 2013). They concluded that children with cochlear implants only had difficulties in retention of producing the word and being able to comprehend it. Fast mapping and extension for children with cochlear implants, compared to same aged children with normal hearing and children with the same vocabularies, proved to be unaffected (Walker & McGregor …show more content…

They examined the infant’s attention to speech to determine language development. The main purpose was to compare whether infant-directed speech or adult-directed speech influenced the infant’s attention to speech. The researchers also wanted to conclude if the infants with cochlear implants payed attention to infant-directed speech and to see if that associated with language development. The results established that infant-directed speech does have an effect on deaf infants, with cochlear implants, attention to speech. Infants with cochlear implants prefer infant-directed speech over adult-directed speech and this has a result on language development (Wang et al.,
