PSY397H5 Lecture Notes - Lecture 2: Morris Water Navigation Task, Cortisol, Conditioned Taste Aversion
Document Summary
Examples of associative conditioning: context and cue dependent fear: In this experiment freezing is measured in time, depending on how long it is frozen for: the next day being placed in the same chamber there are 50-60% of rats freezing. Measuring the cumulative distance from the target is the best measure for this experiment: escape latency: how long does it take for the mouse to get to the platform. Conditioned taste aversion: neophobia: the avoidance of new things. Conditioned taste aversion: unusually long delay between conditioned stimulus (cs = taste) and unconditioned stimulus (us = nausea) and unusually long lasting memory (conditioned response = food avoidance) Slicing the learning pie: categories of learning according to training method, motor (procedural) learning, pavlovian conditioning (stimulus association) - the cs and ucs, operant (instrumental) conditioning (behaviour-outcome association, the motor response is being reinforced.
