Cambridge International Hassett details
| Term | Definition |
|---|---|
| What is meant by 'socialisation'? | The way in which a child is taught to behave in a way that is acceptable within society |
| What was the aim of this study? | To determine whether sex differences in toy preferences observed in humans were also seen in monkeys |
| What species of monkey was used in this study? | Rhesus |
| What was the background to this study? | It had been established that human boys prefer toys with wheels on them, whereas human girls did not show a particular toy preference |
| Why were non-humans used in this study? | In order to decide whether sex differences were the result of gender socialisation in humans, or due to an innate mechanism |
| Why were rhesus monkeys chosen specifically? | They show hormonally biased sexually differentiated juvenile behaviour, but there is no evidence of gender socialisation |
| What method was used in this study/ | Controlled, non-participant observation |
| Describe the sample used in this study. Include as many details as possible | Rhesus monkeys: 61 female, 21 male from a group of 135. Many had data excluded (e.g. because they had fewer than 5 total behaviour), meaning the final N was 23 females and 11 males |
| What was the experimental design in this study? | Independent groups - as they were either male or female |
| What was the main independent variable in this study? | Sex of the monkey |
| What were the two categories of toy that monkeys were presented with? | Wheeled or plush |
| How was preference towards toy operationalised in this study? | Frequency of interaction with toy and duration of interaction with toy |
| Give details of control variables in this study | Monkeys chosen were not part of any hormonal treatment prior to the study, Placement of toys was counterbalanced |
| Why was placement of toys counterbalanced? | In order to avoid favouring one set of toys over another due to a better placement |
| List all of the wheeled toy examples | Wagon, truck, car, construction vehicle, shopping cart, dump truck |
| List all of the plush toy examples | Winnie-the-Pooh, Raggedy-Ann, koala bear hand puppet, armadillo, teddy bear, Scooby-Doo, turtle |
| How many trials were used, and how long did each trial last? | Seven trials, 25 mins each |
| BC: Extended touch | Placing a hand or foot on toy |
| BC: Hold | Stationary support w/one or more limbs |
| BC: Sit on | Seated on the toy or a part of the toy |
| BC: Carry in hand | Moving w/toy in hand and off the ground |
| BC: Carry in arm | Moving w/ toy in arm and off the ground |
| BC: Carry in mouth | Moving w/toy in mouth and off the ground |
| BC: Drag | Moving the toy along the ground behind the animal |
| BC: Manipulate part | Moving, twisting, or turning a part |
| BC: Turn entire toy | Shifting 3-D orientation of toy |
| BC: Touch | Brief contact using hands or fingers |
| BC: Sniff | Coming very close to the toy with the nose |
| BC: Mouth | Brief oral contact – no biting or pulling |
| BC: Destroy | Using mouth or hands to bite or tear toy |
| BC: Jump away | Approach, then back away from toy with a jumping motion |
| BC: Throw | Project into air with hands |
| What percentage of males preferred wheeled toys? | 73% |
| What percentage of males preferred plush toys? | 9% |
| What percentage of females preferred wheeled toys? | 39% |
| What percentage of females preferred plush toys? | 30% |
| Which sex spent signifcantly longer with one type of toy than the other? | Males |
| What did Hassett conclude from this study? | That sex differences in toy preferences are innate and not due to socialisation |
| What link was found between rank and toy type preference in females? | Females who showed no preference (between plush or wheeled) were, on average, of a lower rank than those who showed a preference for plush toys? |
