Document Summary

Ivan petrovich pavlov: got noble price on work on digestion (work ended up being wrong) Classical or pavlovian conditioning: unconditioned stimulus (ucs, us, effective stimulus that unconditionally-automatically and naturally triggers, conditioned stimulus (cs, previously neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response. Classical conditioning: acquisition, an increase in the intensity of the behavior if the cs is presented alone. Extinction: a decrease in the intensity of the behavior if the cs is presented alone, if you present cs alone the animal predicts the tone doesn"t result in food, acquisition (cs+ucs) Drosophila melanogaster: drosophila has hundreds of thousands of neurons. Short term memory leads to long term memory. Other studies show: short term memory leads to middle term memory and then it branched out to long term memory and _____ Backward conditioning used to be used as control. Stimulus conditioning: the cs (light) and ucs (shock) come on and go off at same time.
