Document Summary
A change in an organism"s behaviour or thought as a result of experience. Non-associative = learning about direct properties of a stimulus (a simple form of learning: habituation; becoming less sensitive to a stimulus due to repeated exposure. Eg. ignoring sounds from a road near your house after a few weeks of moving: sensitisation; becoming more responsive to a stimulus in the environment. Eg. if you feel a spasm near your pocket and think it"s your phone. You"ve become used to it vibrating and have become sensitive for it. learning through association due to repetitive pairing. Studied aplysia californicus- a simple organism with a simple ns so that changes due to learning was easily observable. Associative = learning about the relations bw stimuli. Ucr (salivation due to food) automatic, not learned. Probability of response = no. of trials when conditioned response occurs. The cs must precede the ucs (0. 5-10 seconds is best)
