Procedure - Hasset

• Procedure

  
  

  Seven 25-minute trials were completed in the outdoor enclosure, each with a different pair of toys. Before each observation, observers placed a pair of toys (1 wheeled, 1 plush) outside while the monkeys waited inside.
• The toys varied in shape, size, and colour, and were selected on what you could ‘do’ with them.
• Toys

   6 wheeled toys, including a wagon, truck, and car.
• Data Collection = A video camera was focused on each toy to record interactions. 2 observers watched the videos and used a behavioural checklist to categorise the behaviour of the monkeys. They recorded the data using the app Handobs on their palm pilots (a device similar to mobile phones).
• Behavioural checklist included: extended touching, holding, sitting on, dragging, carrying, etc.
• Examples of operationalised behaviours:

  • Extended touch – Placing a hand or foot on the toy.• Sit on – Seated on the toy or a part of the toy.
• Toys were placed 10 metres apart and their positions were counterbalanced (to ensure the monkeys didn’t prefer a certain area of the enclosure).
• 7 Plush toys, including a Winnie-the-Pooh, Raggedy Ann, and Scooby Doo doll.
