Sex Differences in Rhesus Monkey Toy Preferences

These flashcards cover key concepts and findings from the study on sex differences in toy preferences in rhesus monkeys, comparing them to similar findings in children.

What is the primary focus of the study by Hassett et al. regarding rhesus monkeys?

The study investigates sex differences in toy preferences in rhesus monkeys and compares these preferences to those observed in children.

What type of toys were males and females compared on in the study?

Males and females were compared on their interactions with wheeled toys (masculine-type) and plush toys (feminine-type).

What significant preference did male monkeys show in the study?

Male monkeys showed a strong and consistent preference for wheeled toys over plush toys.

How did female monkeys' toy preferences differ from those of males?

Female monkeys exhibited greater variability in their preferences and did not show a significant preference for either toy type.

According to the study, what factors are thought to shape sex differences in toy preferences?

Sex differences in toy preferences are thought to be shaped by both biological influences (such as hormones) and socialization processes.

What hypothesis did the authors propose regarding toy preferences?

The authors hypothesize that toy preferences reflect hormonally influenced behavioral and cognitive biases molded by social processes.

What evidence suggests that biological predispositions may influence toy preferences?

Girls with congenital adrenal hyperplasia (CAH) show more boy-typical toy preferences, suggesting that hormonal exposure influences preference.

How does the toy preference of juvenile male monkeys compare to that of female monkeys according to the findings?

Juvenile male monkeys engage in more rough and tumble play, while female monkeys show greater interest in infants.

What methodological approach did the researchers take to assess toy preferences in monkeys?

The researchers conducted trials presenting monkeys with simultaneous access to wheeled and plush toys to directly measure preferences.

What overall conclusion can be drawn from the study regarding sex differences in toy preferences?

The study concludes that sex differences in toy preferences in rhesus monkeys parallel those observed in humans, suggesting a biological basis for such preferences.
