Metro State University [Article Review Summary]
The study conducted by Ozonoff et al. (2014) was aimed to determine the prevalence of atypical development in accordance with the occurrence of the broader autism phenotype among the sibling of children with autism spectrum disorder. The study was also objectified to identify the age at which the atypical development can be observed while determining the developmental domains that are highly affected due to the prevalence of atypical development. The study proposed that the prevalence of atypical development can be identified during the early two years of development, while effecting the language, motor cognitive and …show more content…
All the measured were comprised of scale questions that were responded by the clinicians after observing the infants at the given intervals by using the structured questionnaire. In the initial phase, the participants were recruited by means of assessing their siblings for autism using the Social Communication Questionnaire and Autism Diagnostic Observation Schedule (ADOS) (Ozonoff et al., …show more content…
Moreover, residual analysis was also conducted to determine the change in the extent of pattern. The results of the study indicated that 28% of the high-risk infants group accounted for Non-Typical Development which was comprised of low Mullen score and increased ADOS score. Additionally, the growth curve models indicated that Non-Typical Development group at the age of 36 months was not different from the results at 6 months, whereas empirical significance was observed at the age of 12 months (Ozonoff et al., 2014).
The results also indicated that Non-Typical Development group accounted for the atypical development prevailed in the motor, language, cognitive and social domains. However, significant inhibition was observed in the domain of social communication. The overall findings indicated that the prevalence of atypical development, in accordance with the occurrence of autism can be identified by the age 12 months. The inhibited development in social, motor, language and cognitive domains can be a significant predictor of autism (Ozonoff et al.,
