PSYC 122 Lecture Notes - Lecture 12: Donald Griffin, Animal Echolocation, Honey Bee
Document Summary
Mechanisms that we use to identify food, with senses. The animal produces a high-frequency pulse of sound and listens for the echo to determine the location of objects and prey. The systm is so precise, bats can recognize the type of insect from echolocation alone. The primary salient feature is the wing flutter of the insect species. May also detect electrical impulses and magnetic fields. So sensitive that it can pick up magnetic changes in the earth, could be how they migrate to long periods olfaction dogs. In vertabrates- receptors in the nasal epithelium detect molecules specific to particular smell. Dogs have 100 times more receptors than humans. We have very specific aspects but not all animals do. Rat observer will always choose cinnamon when previously sees a demonstrator eat a cinnamon food- cause tells rat its an ok thing-
