Individuals with Autism Spectrum Disorder (ASD) and the Broad Autism Phenotype (BAP) are more likely than individuals with typical development (TD) to report a sexual minority orientation (e.g., Bejerot and Eriksson, PLoS ONE 9:1-9, 2014; DeWinter et al., Journal of Autism and Developmental Disorders 47:2927-2934, 2017; Qualls et al., Journal of…

This is the first study to evaluate an autism intervention model, the parent-delivered Early Start Denver Model (P-ESDM), for young children with fragile X syndrome (FXS), a known genetic disorder associated with autism spectrum disorder. Four parent-child dyads participated in a low-intensity, parent coaching model of the P-ESDM to evaluate…

Existing models of autism spectrum disorder (ASD) disagree as to whether the core features should be conceptualized as convergent (related) or divergent (unrelated), and the few previous studies addressing this question have found conflicting results. We examined standardized parent ratings of symptoms from three domains (social, communication,…

ASD is one of the most heritable neuropsychiatric disorders, though comprehensive genetic liability remains elusive. To facilitate genetic research, researchers employ the concept of the broad autism phenotype (BAP), a milder presentation of traits in undiagnosed relatives. Research suggests that the BAP Questionnaire (BAPQ) demonstrates…

The formation and function of the mammalian cerebral cortex relies on the complex interplay of a variety of genetic and environmental factors through protracted periods of gestational and postnatal development. Biogenic amine systems are important neuromodulators, both in the adult nervous system, and during critical epochs of brain development.…
