PSYCHOLOGY: Hassett et al.
1. Outline the debate over toy preference.: View 1
- Socialization processes primarily shape toy preference.
View 2
- Biological factors determine toy preference.
View 3
- Hormones are the source of differences. (Girls with CAH show masculine toy preference, when encouraged to play
with female toys, they reject and continue play with traditionally male toys.)
2. Explain the prior research of Hassett et al.: In 2002, Alexander and Hines did a study with vervet monkeys.
- Proportion of males toy interactions with masculine toys was greater than the pro- portion of females interactions with
masculine toys. (Males interacted with masculine toys more than females)
- Authors suggested that the preference for masculine toys implied boys preferences for masculine toys reflected stronger
gendered socialization of boys toy preference relative to girls.
- In the Alexander/Hines study, the monkeys were not presented with actual choices, findings limited to cross-sex
willingness to play with any toy.
3. State the aims of the study Hassett et al.: - Investigate the sex differences in toy preferences of rhesus monkeys
- See if socialization processes or biological mechanisms affect sex stereotypical toy choice.
- See if there are sex differences in toy choice of rhesus monkeys compared to human children
4. Identify the sample and sampling technique of Hasset et al.: Opportunity sampling
135 monkeys from the National Primate Research Center Field Station (Atlanta, Georgia)
14 were on hormonal treatments and not included 39 infants were not
included

, PSYCHOLOGY: Hassett et al.
*61 FEMALES AND 21 MALES.
Housed in 25mx25m outdoor compounds with temperature controlled indoor quar- ters
Water was continuously available
Fed monkey chow twice daily; supplemented once per day with fruits and vegetables.
5. State the type of experiment and research method of Hasset et al.: Labora- tory experiment
Observations Controlled
Non-participant Covert
Structured (Time/event sampling)
6. Describe the type of data collected in Hassett et al.: Quantitative Calculated average frequencies
and durations for each behavior
7. Provide several behaviors from the behavioral checklist of Hassett et al.: -
Extended touch Hold
Sit on
Carry in hand Carry in
arm Carry in mouth
Drag Manipulate part
Turn entire toy Touch
Sniff Mouth
Destroy Jump
away Throw
8. State the IV's of Hassett et al.: Monkeys genders (Male, female)
9. State the DV's of Hassett et al.: Whether or not the monkeys interacted with the toys
Social rank Age
10.Describe the experimental design of Hassett et al.: Independent measures since two groups of monkeys were
compared: Males, females
