  2. Are men or women better at recognizing family resemblance? Folk psychologists predict that women will be better at recognizing differences due to the belief that women are better than men at social tasks. Evolutionary psychologists predict that men will be better at recognizing differences due to paternity confidence and potentially due to natural selection. Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  3. Folk Psychologists They were approached at an outdoor fair 64 out of 65 thought women would be superior at recognizing family resemblance Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  4. Evolutionary Psychologists They were approached at a conference 13 out of 19 predicted that men would do better at recognizing family resemblance Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  5. Methods 200 Caucasian parent/child photographs (only 24 were used) Father/daughter Father/son Mother/daughter Mother/son Only ½ were related Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  6. Methods cont’d 8 additional single photos were added to asses the ability to recall faces 4 had been seen before, 4 hadn’t 200 subjects used (92 males, 108 females) Motivated by $50 reward if they got the highest score Asked to mark “yes”/”no” to affirm parent/child relationship Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  7. Results Women and men equal in ability to judge family resemblance Both sexes were better able to judge resemblance for mothers Men and women were better at judging relatedness for children of their own sex Women were superior at the ability to recall faces Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  8. Discussion Ability is not influenced by demographics (age, number of children, number of siblings, education, or marital status) Researchers proposed that the ability to recognize family resemblance doesn’t improve by experience, but rather is an aspect of social intelligence Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  9. Discussion cont’d Critique of Folk psychology Generalization that women tend to be better at social tasks (very common and consistent error) Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  10. Discussion cont’d Critique of Evolutionary psychology Individuals did not spend enough time on question Put too much importance on paternity confidence and ignored other factors Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  11. Conclusion Sex differences would not result from natural selection Cost of maintaining the mechanism is small Same benefits to both sexes Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  12. Critical Review The study had an unbalanced number of folk psychologists vs. evolutionary psychologists They had an insufficient sample of humanity (only used Caucasians for photographs) They didn’t specify what the race of their sample was (it has been shown that it is easier to identify differences among peopleofyour own race) Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21

  13. Any questions??? Nesse, R.M., Silverman, A., & Bortz, A. (1990). Sex Differences in Ability to Recognize Family Resemblance. Ethology and Sociobiology. 11, 11-21
