The research design was based on the intervention program which incorporated language measures, measures of non-verbal intelligence and vocabulary skills of the sample. The researcher has utilized standard measurement and assessment protocols for each examination.
SD (Standard Deviation), PTA (Pure Tone Average), DEIP (Diagnostic Early Intervention Program), TC (Total Communication), FM (Frequency Modulate), PPVT (Peabody Picture Vocabulary Test), EOWPVT (Expressive One-Word Picture Vocabulary Test), SE (Standard Error) and PLAI (Preschool Language Assessment Instrument).
The researcher of this study has acquired the previous experience through literature that appropriate interventions can help deaf or hard of hearing individuals to achieve language abilities similar to a hearing and normal individual. Several empirical researches have influenced the researcher to utilize and assess the outcomes of language intervention on deaf children’s linguistic capabilities.
The researcher of this study has examined every deaf and hard of hearing child using standard protocols of EOWPVT and PLAI after the completion of DEIP. Every test was conducted in a separate setting and time on the whole sample.
The study explored that the impact of DEIP is significantly better in those children who were enrolled in a younger age than those who were enrolled later. The negative correlation of enrolment age and language outcomes was found at the age of 5 years in the whole sample. The degree of hearing loss did not have a significant impact in the measurements and ...Show more
