Baron-Cohen (2003) proposed that males are predisposed to learn about objects and their mechanical interactions, whereas females are predisposed to learn about people and their emotional interactions. He cited as evidence an experiment conducted on newborn infants Wheelwright, Batki, & Ahluwalia, 2000). Infants viewed, side by side, an active and expressive person and a similarly sized inanimate object. Male infants looked longer at the object, whereas female infants looked longer at the person. Baron-Cohen suggested that male infants’ focus on objects leads them to become systemizers who engage both with the mechanical world and with abstract systems like mathematics.
