Unformatted text preview: I. Examples of Learning Besides Classical, Operant A. Complex: Honeyguide Behavior B. Simple: One-stimulus Learning I. An Ecological View: Learning is Helpful, Specific A. Features of Taste Aversion Learning B. Imprinting C. Play 1. What is it? 2. Who does it/ whats its function? From Thursday How would you answer a person who says that what we claim to be learning [e.g. learning to avoid prey that have bright markings] is really just instinct [e.g. animal is born w/ ability to avoid brightly colored animals]? point out it is not an either/or question give examples of situations where animal does not know something at first, but gains that information over time point out that while some species might rely on instincts, others might NEED learningspecifically, long-lived animals that live under changing circumstances. give examples of complex learning Crows---tool use and complex learning. VIDEO Using and ALTERING a tool (without being taught) to reach a food item. Dropping nuts into street crosswalks so cars crack them Laboratory chimpanzees---young chimpanzees outperform college students on a short-term memory task Honeyguides---Lead humans to bees nests to get honey. Involves fairly complex learning. VIDEO Approach when called (simple associative learning) Spatial learning---Find specific location over 1 mile away Communication w/ humans Adjust behavior to humans actions (e.g. go back if they are not following) Single-Stimulus Learning Habituation--the relatively persistent waning of a response that results from repeated stimulus presentations without any consequences.-Getting used to a new object or noise-Getting used to a human observer, thus acting normally-For conservationists, getting used to humans can be a bad thing (no healthy fear of hunters, poachers) Usually, habituation is beneficial because it saves energy and time, which can then be used to pay attention to other important activities. Single-Stimulus Learning Sensitization--increase of a response that results from repeated or constant stimulus presentation.-Responding to repeated annoying sound like snoring or sniffling-Perhaps getting seasick from boat movement An Ecological View --- Not all learning is the same. It serves specific purposes for specific species, and is subject to natural selection. Conditioned taste aversion: avoiding a food that makes you ill because cues associated with that food become unpleasant. It is a very strong, specific learning: 1-trial learning possible Can have a long delay from the cue to the unpleasant effect Also the TYPE of cue, or conditioned stimulus, is important Garcia and Koelling [1966] exposed rats to gamma rays [producing nausea] following one of 2 CSs: 1] a tone/light...
