PSYC 720 Lecture Notes - Lecture 3: Evolutionary Arms Race, Detection Theory, Monarch Butterfly
Document Summary
A warning signal associated with the unprofitability of a prey item to potential predators (ie. being conspicuous: example: bright colors of poisonous animals. M llerian mimicry: two or more species have very similar warming signals and share genuine anti-predation attributes: example: viceroys and monarch butterflies. Batesian mmicry: the mimic shares signals similar to the model, but does not have the attribute that makes it unprofitable to predators: essentially, one is actually poisonous and the other is not, but they look the same. Electrophysiology: single cell studies, neural sensitivity. Recording natural behaviors: in field or in lab, detailed understanding of behavior required, behavior may be confounded with variables. How bright must a light be to detect it: discrimination. Different cells = different sensitivity: hubel & weissel experiment. Records from particular cell during a stimulus showing. Each cell is only interested in one particular stimulus.
