They reported their gender and were assessed with the BFAS, STA, EQ and the SQ-R. Results 2: Hierarchical regression to predict Schizotypal Personality Assessment (STA) scores General personality dimensions associated with EB strengthened some aspects of both EFB and EMB theories while weakening its other claims: 1)The significant contribution of Compassion and Politeness toward heightened EB supports the hypothesis that the EFB is associated with hyper-mentalizing (Crespi & Badcock 2008). 2)That Orderliness predicted the decline of EB is consistent with the notion that Autistic symptomatology, which is comorbid with Obsessiveness (Lewis et al. 2011), characterizes the EMB (Baron-Cohen 2002). 3)Intellect negatively predicting EB is in line with the EMB hypothesis that the male cognitive pattern is associated with scientific engagement (Kaufman et al. 2015). 4)Schizotypy as measured by STA was predicted by Withdrawal, suggesting that STA measured behavioral inhibition mediated negative symptoms (DeYoung, Quilty & Peterson 2007). 5)That systemizing is related to negative symptoms, which are more common in males, emerged as SQ-R contributed unique variance beyond the aspect of Withdrawal in predicting STA.
