| Summary: | The anchoring effect, very well-known and robust, has never been shown in non-human subjects. Based on Frederick and Mochon's proposal of a scale distortion theory that explains the anchoring effect in humans (2011a), this research project aims to test scale distortion in capuchin monkeys (Sapajus apella). The main research question was: What is the effect of exposure to a numeric anchor prior to solving a quantity discrimination task in capuchin monkeys? To answer that question, 6 capuchin monkeys were tested in a total of 1191 trials of a quantity discrimination task in which they had to choose one out of two containers with different amounts of peanuts. A change in their response patterns due to anchor exposure was expected. The 5 monkeys that understood the task were not able to consistently choose the higher amount as capuchin monkeys have been shown to do in similar tasks multiple times in the past... |
