Table 1 Descriptive statistics for the Adult Developmental Coordination Disorder Checklist (ADC), Autism Spectrum Quotient (AQ), autostereogram self-assessment (ASA), and Stereopsis Screening Inventory (SSI) (n = 650). Clinically significant impairment is based on Coren and Hakstian [56], Kirby et al. [57], and Baron-Cohen e al. [58]
From: Does stereopsis account for the link between motor and social skills in adults?
