Document Summary
Change in an organism"s behaviour or thought as a result of experience. Sensitization: responding more strongly to the same stimulus over time. Habituation: responding less strongly to the same stimulus over time. British associationists (1800"s): school of thinkers who believed that we acquire all of our knowledge by conditioning. Once connection is made, we only need one element to retrieve the other from memory. Simple associations = mental building blocks for higher order thinking. Most famous for work on digestion of the dog. Made an unexpected discovery about how animals learning. Metronome went from neutral stimulus to condition salivate when dog salivates by listening to metronome. Neutral stimulus (ns): does not elicit a particular response i. e. metronome. Pair the ns repeatedly with the unconditioned stimulus (ucs), which elicits an unconditioned response (ucr) Eventually, the ns becomes a conditioned stimulus, eliciting a conditioned response i. e. , metronome elicits salivation.
