Document Summary
Life sci 2d03: chapter 5 learning and cognition. Learning: a relatively permanent change in behavior as a result of experience. Adults (<1 y/o: provided food that required different levels of manipulation (chewing) based on size. The handling time of each food item was recorded: found that adults had the lowest handling time and recently fledged birds had highest. This also led to differences in energy intake rate (same as above: concluded the differences is to differences in experience. Animals learn in order to modify their behavior to deal with dynamic and changing environments: two factors affect evolution of learning: environmental stability and reliability of past experience. Independent of each other, but not mutually exclusive. Increase in environmental regularity decreased favor for learning. Increase of reliability of past experience increased favor for learning: there needs to be a predictable relationship between experience and the best option now available.
