Realized that dogs learned to make connections about the stimulus that signals the food and the actual food. That occurs when a neutral object comes to elicit a reflexive response. When the neutral stimulus is associated with another stimulus that produces that reflex. Put meat powder on tongue: led to salivation (natural reflex) Played a metronome (at the same time: did not lead to salivation (neutral stimulus) Part 2 (done over and over; conditioning trial) Metronome sounded, a few seconds later, meat powder was put on tongue: this pairing led to salivation. Metronome sounded but no meat powder presented (critical trial: led to salivation. Neutral stimulus doesn"t automatically trigger reflexive response (metronome) Unconditioned stimulus (us/ucs) elicits reflexive (unlearned/automatic) behavior (meat powder) Unconditioned response (ur/ucr) automatic response to ucs (drooling)
