The exact time of the shift can hardly be predicted in typically developing children and might be even less predictable in children with atypical development.
Individuals with Autistic Disorder were found to exhibit significantly more feeding and sleep difficulties than those with PDD-NOS, who in turn presented with more difficulties of this type than those with atypical development.
Four adolescents with atypical development were taught to conditionally relate visual stimuli of two distinct sets (AB relations).
Disruption of these networks can lead to disorders of sex development (DSD), which are congenital conditions with atypical development of the chromosomal, gonadal or anatomical sex [2].
Relative pitch is a more musically relevant mode of pitch processing than AP, which is actually associated with atypical development (e.g., autism [12], [13]; Williams syndrome [14]) and with non-human auditory processing [15], [16].
Even centile ranks near the recommended cut-off points to identify infants with atypical development (10th centile at 4mo and 5th centile at ≥8mo) 19 should not be used in isolation to make clinical decisions regarding follow-up or intervention.
While these models have been discussed with respect to atypical development (e.g. gene environment models in Williams Syndrome; Karmiloff-Smith, 2006), there has been no formal empirical testing of these contrasting hypotheses in the early development of ASD.
This study had 3 goals, which were to examine the following: the frequency of atypical development, consistent with the broader autism phenotype, in high-risk infant siblings of children with autism spectrum disorder (ASD); the age at which atypical development is first evident; and which developmental domains are affected.
We propose that these findings portray an altered configuration of working memory function in the brain, potentially indicative of an adaptive response to atypical development associated with the manifestation of PEs.
Older mothers may have more experience with child development, increasing their recognition of "atypical" development and their desire for services, and lower unmet needs likely enabled mothers to work more.
Instead, activation of this network was consistently decreased for children with epilepsy across childhood, suggesting a pattern of atypical development.
