Question 1: List the reasons Singh (1993) gave for why he hypothesized that selection produced adaptations for male preference for low WHR. Describe the stimuli Singh used to test his hypothesis. What WHR did men in his study find most attractive?

Question 2: According to Lassek & Gaulin (2005), what is the function of gluteal femoral fat? What was the relationship between female WHR and cognitive performance? What was the relationship between female WHR and offspring cognitive performance?

Question 3: What was the "weight" and WHR of the line drawings Yu & Shepard (1999) presented to Machiguenga men? Which stimuli did more remote Machiguenga prefer? Which stimuli did more acculturated Machiguenga prefer? How do Yu & Shepard explain this pattern of results?

Question 4: According to Sugiyama, what is the problem with Yu & Shepard's explanation for the differences between remote and acculturated Machiguenga men's preferences in their study?

Question 5: Sugiyama (1996, 2004) hypothesized that WHR preference would be calibrated to the range of variation in the local population. What was the mean female WHR in his Shiwiar sample? When presented with all 12 of Singh's original stimuli, which figures did Shiwiar men prefer? When Sugiyama presented only line drawings of women within a weight class, what did Shiwiar men prefer?

Question 6: What were the basic results of both Marlowe & Wetsman's (1999) study of WHR preference among the Hadza? Did Marlowe, Apicella & Reed's (2005) study of WHR preference among the Hadza come to the same basic conclusions regarding whether or not Hadza men had preferences for low WHR? Were the results similar or different, and why?

Question 7: Tovee et al. used silhouettes of actual women in their study of WHR preference. What did they find regarding the relative importance of BMI and WHR in assessments of female attractiveness? According to Sugiyama, why are these conclusions unlikely to be valid?

Question 8: Sugiyama & Blackwell presented stimuli derived from the same individuals from childhood through adulthood. What was the age range of the figures found most attractive? Based on this preference, and data from Tanner & Whitehead on growth and development in this sample, what aspect of female mate value does male preference appear to be targeting?

Question 9: Even though female Shuar WHR is higher than in Western populations, does WHR still distinguish between females and males? Does Shuar BMI differ by sex? There is no significant relationship between BMI and WHR among the Shuar: can preferences for WHR be a byproduct of preference for BMI? Among Shuar, is WHR related to women's total live births? If so, how?
