The BAPQ has demonstrated a high sensitivity (>70%) to detecting these phenotypes and therefore was suitable for use in this study to provide an indication of current behavioural traits associated with the autism phenotype. An independent-samples t test indicated a highly significant difference between groups on total BAPQ score as the autistic participants scored much higher than the neurotypical participants, t (26) = 4.56, p < 0.001, d = 1.79 (see Table 1 ).
