• Nature verses Nurture

Introduction
• Small differences in behaviors between men and women
• Nature versus nurture debate• Specifically, women are more skilled at social interaction than men

A study of Turner’s Syndrome
• You all remember, right?!• Only one chromosome - which one?• Child develops into a female• Study:
To determine whether differences would be obvious between TS individuals depending on whether their X chromosome was maternally or paternally derived
• Findings: Paternally derived X chromosome yielded lower social-cognitive dysfunction than those that were maternally derived
Normal boys also scored lower on social-cognitive dysfunction than normal girls.

Turner’s Syndrome (continued)
• Explanations: Boys are less socially skilled and more vulnerable to
developmental disorders• Conclusions of Skuse et al. (1997):
Evidence that the origin of the X chromosome (either maternal or paternal) plays a role in the development of sexual dimorphism in social behavior

Conclusions of Choi
• Gene expression depends on internal and external factors
• Society’s responsibility to establish an equal foundation where biology and genetics are balanced when comparing sexes
• The genetic makeup of chromosomes highly influences your social abilities

Test Questions
• 1. What determines sex differences? A. Nature B. Biology C. Nurture D. Both A & C
• 2. Turner’s Syndrome is a genetic condition in with the individual has A. no gonads B. no ovaries C. two sex chromosomes, one inherited from each parent. D. none of the above
• 3. Who is the least socially competent? A. Turner’s Syndrome, maternally derived X chromosome B. Turner’s Syndrome, paternally derived X chromosome C. Normal girls D. Normal boys
True or false?• 4. Boys are more vulnerable to developmental disorders.• 5. Men are more skilled at social interaction than women.• 6. Gene expression changes depend upon both the internal and external
environments.

Critical Review
• Interesting points: Male gene is responsible for social cognizance in
Turner’s Syndrome. This is genetically derived!
Those with Turner Syndrome are even more social than most females!
For an equal society, it is necessary to see how nature and nurture intermingle and how they relate to sex differences
• Unclear points: Why she talks about developmental disorders (e.g. autism)
with no background information The kind of questionnaire distributed was not discussed She doesn’t take evolutionary changes into consideration
when talking about how males will always be stronger than females
