Document Summary
Classical conditioning is the simplest mechanism whereby the relationship between two stimuli is learned about so that future behaviour can be changs. Classical conditioning capitalizes on the predictable sequence of events in the environment, if one stimulus reliably precedes another stimulus, then these two stimuli can become associated. Pavlov"s discovery of classical conditioning came about through work on digestion. Vul"fson studied the salivary reponse of dogs when various substances were placed in mouth. Snarskii looked at salivary response to artificial substances and black water. Object learning: when the dogs learned to associate a visual feature of the water with the flavour. Unconditional stimulus: elicits a response without learning, usually biologicall relevant. Conditional stimulus: is learned about, wouldn"t elicit response when presented the first time and needs to be paired with an us to cause a response. If a response is elicited by the cs, learning has taken place.
