question 83

Essay

In the metacognition experiment described in the text, a monkey was shown a sample and then given a choice: It may proceed with the trial, or skip the trial and get a piece of not-so-yummy monkey chow. If it proceeds, it is presented with several stimuli and must choose the one it was just shown. If the monkey chooses correctly, it gets a yummy peanut. If the monkey chooses incorrectly, it gets nothing and experiences a longer wait before the next trial. The monkey became more likely to skip the trial as the time between the sample presentation and the choice to proceed increased. How does this experiment assess metacognition?
