Stuart, Nicole; Whitehouse, Andrew; Palermo, Romina; Bothe, Ellen; Badcock, Nicholas – Journal of Autism and Developmental Disorders, 2023
Reduced eye contact early in life may play a role in the developmental pathways that culminate in a diagnosis of autism spectrum disorder. However, there are contradictory theories regarding the neural mechanisms involved. According to the amygdala theory of autism, reduced eye contact results from a hypoactive amygdala that fails to flag eyes as…

Zapparrata, Nicole M.; Brooks, Patricia J.; Ober, Teresa M. – Journal of Autism and Developmental Disorders, 2023
Autism spectrum disorder (ASD) is a complex neurodevelopmental condition affecting information processing across domains. The current meta-analysis investigated whether slower processing speed is associated with the ASD neurocognitive profile and whether findings hold across different time-based tasks and stimuli (social vs. nonsocial; linguistic…

Reichow, Brian; George-Puskar, Annie; Lutz, Tara; Smith, Isaac C.; Volkmar, Fred R. – Journal of Autism and Developmental Disorders, 2015
Rett syndrome (RTT) is a neurogenetic disorder in which a period of typical development is followed by loss of previously acquired skills. Once thought to occur exclusively in females, increasing numbers of male cases of RTT have been reported. This systematic review included 36 articles describing 57 cases of RTT in males. Mutations of the MECP2…

Earlier autism diagnosis, the importance of early intervention, and development of specific interventions for young children have contributed to the emergence of similar, empirically supported, autism interventions that represent the merging of applied behavioral and developmental sciences. "Naturalistic Developmental Behavioral Interventions…

Kang-Yi, Christina D.; Grinker, Roy R.; Mandell, David S. – Journal of Autism and Developmental Disorders, 2013
This paper reviews the literature on early child development among Koreans, with a focus on autism spectrum disorders (ASD). The literature review of 951 abstracts in English, 101 abstracts in Korean and 27 full articles published from 1994 to 2011 was performed to understand the presentation of and response to ASD in Korean culture. Based on…

Courchesne, Eric – Journal of Autism and Developmental Disorders, 1995
In a study by Toshiaki Hashimoto and colleagues (EC 611 142), 10 infants with developmental delay, poor eye contact, and poor facial expression underwent magnetic resonance brain imaging and were later diagnosed with autism. This offered direct evidence of abnormality of the cerebellar vermis and the brainstem at the beginning stages of behavioral…
