Dataset: Exploring the Relationships Between Autism Traits, Face Recognition Abilities, Cradling Preferences, and Personality Traits

Autism, prosopagnosia, and atypical cradling are linked to altered lateralization and socio-emotional patterns. This study explores how autism traits, cradling-side preferences, and face recognition abilities predict personality traits. Three-hundred neurotypical adults (150 males) completed a survey including the autism spectrum quotient (AQ), imaged cradling preferences, Prosopagnosia index-20 (PI-20), and the Big Five Personality (BFQ). Results showed a strong LCB, unaffected by sex, handedness, parental status, autism traits, or face recognition abilities. AQ negatively predicted Extraversion, Agreeableness, Emotional Stability, and Openness. LCB correlated with higher Agreeableness and moderated the negative association between AQ and Extraversion. These findings suggest cradling preferences and autism traits influence personality, possibly reflecting reduced right-hemisphere specialization in emotional processing and social behavior.
