Hasset et al Experiment profile
The psychology being investigated
Play
Sex differences and the role of nature
Socialistaion and the role of nature
Hormones and toy prefernces
Research methodolgy
IV: Sex of the monkeys
DV: Whether the monkey interacted more with the plush or wheeled toys
Experiment
Not necessarily a lab or field experiment
Aims
Aim 2
To investigate if male and female rhesus monkeys have similar toy preferences to human infants despite no socialistaion experiences with humans
Aim 1
To test if sex differences in children's toy preferences result from biological factors - CAH or rather through socialisation
Sample
135 monkeys
-39 to young to identify biological sex
-48 no significant interaction with any toy
-14 prenatal hormones
Total sample: 34 monkeys
23 Females
11 males
Procedure
The observers placed a pair of toys (1 plush & 1 wheeled) in the outdoor area while the monkeys waited inside
A video camera was focused on each toy for analysis
Seven 25 minute observations were completed in the outdoor area of the monkeys enclosure
Standardisation of procedure
There were 2 observers to avoid an observer bias
Each toy type had a fixed size range
Used palm pilots to calculate accurate interaction duration's
Used a behavioral checklist
The position of the toys were counterbalanced
Results
Males spent more time with wheeled toys
Male monkeys prefer wheeled toys
No significant time differences in female monkeys
Positive correlation between rank of the monkey and the time spent interacting with a toy
Female monkeys showed no consistent preferences
Conclusions
Toy preferences in humans may result from biological sex differences
Human toy preferences as with monkeys reflect hormonal influence d behavioral and cognitive biases
