Document Summary

There are 4 major categories of learning; 3 are relatively simple and the fourth is more complex. ----classical conditioning: involves an association between two stimuli (neutral and unconditioned) ----instrumental (or operant) conditioning: involves an association between a stimulus and a response. There are 4 key elements to classical conditioning: us, ur, cs, and cr. What is the relationship between these elements before, during, and after training? (hint: see text definition on p. 436 and slide 6, lecture 20) Us = puff of air; ur = eyeblink. Cs = 1000-hz tone; cr = eyeblink: before training: us --> ur, cs , during training: cs + us --> ur, after training: cs --> cr. In eyeblink conditioning, the motor neuron responsible for eyeblink receives 2 synapses: one (we"ll call. Synapse p) from a touch neuron activated by the air puff on the eye and the other (we"ll call synapse t) from an auditory neuron activated by the tone.
