Document Summary
The pairing between an unconditioned stimulus (ucs) and an unconditioned response (ucr) is given by nature. Food (the ucs) automatically produces salivation (the ucr). The sound of a tuning fork (the cs) precedes and predicts the presentation of food (the ucs). Food powder: for optimal learning (under most circumstances), the cs must precede and predict the ucs, precede, predict. Robert rescorla: dogs had the opportunity to learn the relationship between a tone (cs) and a shock (ucs) to learn to escape the shock. Pavlov"s dogs began to salivate before they got the food powder: for video, classical conditioning demonstration, we know that you"ve been conditioned when: * the cr occurs in the absence of the ucs: generalization: rabbits were trained so that they produced a conditioned response (they closed their outer eyelid) when they heard a 1000 hertz tone (siegel et al. , 1968). Pavlov"s dogs would salivate on trials that omitted the food powder: stimulus discrimination: shenger-krestovnikova.
