Question.810 - In the Evolutionary Psychology & Gender Mini Lecture, I talk a lot about what the traditional evolutionary psychological ideas have been with regard to gender (e.g. men try to reproduce with as many women as possible and avoid investing in any one child; women try to find reliable men who will be monogamous, loyal, and who WILL invest in the few children they bear during their reproductive years). The Gettler et al. article is an example of more modern scholarship in this area that complicates these traditional ideas and suggests that human males may be more "wired" to care for children than we previously thought.? Please read the article, which can be found?here?Download here. Then, please answer the following questions: When they talk about T, what are they referring to? (1 point) Is this study correlational/observational or experimental? Why? (3 points) Why is this considered a longitudinal study? (2 points) How many men are in the sample? (1 point) In what country did this study take place? (1 point) The authors used data from a health survey and also went into the field and collected testosterone samples from men who had participated in the health survey. What was the survey called? (1 point) The authors hypothesized that men with higher T at the beginning of the study would be more likely to partner (because men with higher testosterone tend to be more successful at finding a partner and producing children).??Did they find support for this hypothesis? (2 points) The authors also hypothesized that men who became fathers would see a decrease in their T after the birth of their babies. The idea is that men's - not just women's - bodies might be "wired" to adapt hormonally to taking care of babies. Lower T means a more nurturing, less aggressive father. Did they find support for this hypothesis? (2 points) Finally, the authors hypothesized that men who spent more time caring for their children would see an even steeper decline in T. The idea is that human bodies respond biologically to events in their environment, and time spent caring for a baby might be negatively correlated with testosterone. (In other words, it's a snowball effect - the more you care for a baby, the more nurturing/less aggressive you get.) Did they find support for this hypothesis? (2 points) Finally, do the results of this study surprise you? Why or why not? (3 points) Bonus question, worth up to 3 points:? Why was it important that this study be longitudinal (studying the same people over a long period of time) rather than cross-sectional (comparing the testosterone of a group of men who haven't become fathers yet to a group of men who have already become fathers)??
