There have been major advances in science and technology related to hearing impairments over the past 30 years, however, there continues to be an absence of change seen within the deaf and hard-of-hearing population and their language development. The average deaf high school graduate demonstrates language levels below the average fourth-grader. Yoshinaga-Itano, Sedey, Coulter and Mehl’s (1998) research focused on comparing the receptive and expressive language skills of early- and later-identified children with hearing loss. Data was collected from 150 deaf (uses standard American Sign Language (ASL) to communicate) and hard-of-hearing (use other devices to communicate (hearing aids, cochlear implants, etc.)) children. All the children involved received intervention services between one …show more content…
Although, a few limitations existed; sample sizes were relatively low, most research was limited in degrees of hearing losses or failed to account for demographic variables associated with language development. Yoshinaga, et. al., worked to avoid such limitations by gathering data from a large sample (150 children), not constricted to high risk criteria, which allowed for the full spectrum of hearing loss (mild to profound) and in analyzing the data, they accounted for demographics such as, cognitive ability, age at testing, mode of communication, gender, degree of hearing loss, minority status, socioeconomic status, and whether additional disabilities were active. However, to acquire definite results, the researchers would have obtained a random sample of children, arbitrarily assigned to each group, early or later identified. In doing so, the later identified group would be withheld early intervention services due to later identification resulting in unethical practice, therefore, early and later identified groups in this population have to be naturally occurring in order to
