Broader Autism Phenotype and Nonverbal Sensitivity: Evidence for an Association in the General Population

This study examined the relationship between characteristics of the Broader Autism Phenotype (BAP) and nonverbal sensitivity, the ability to interpret nonverbal aspects of communication, in a non-clinical sample of college students. One hundred and two participants completed a self-report measure of the BAP, the Autism Spectrum Quotient (AQ), and two tests of nonverbal sensitivity, the Test of Nonverbal Cue Knowledge (TONCK), and the Diagnostic Analysis of Nonverbal Accuracy 2 (DANVA2). AQ score was correlated with TONCK performance and number of errors on the adult faces subtest of the DANVA2, but not adult paralanguage or postures. These findings suggest that characteristics of ASD in the general population are associated with differences in both explicit and implicit knowledge of nonverbal cues.
