Orienting response: any response to which an organism directs appropriate sensory organs (eyes, ears, mouth) toward source of stimulus i. e. an automatic response. Classical conditioning involves learning about conditions that predict that a certain significant event will occur: classical conditioning: stimulus (the ucs) comes to be controlled by another stimulus (cs) process by which a response normally elicited by one ex. Pavlov"s experiment pavlov rang a bell at the beginning of the experiment. The dogs did not salivate; there is no link between salivation and the bell. However, if food (ucs) was presented to the dog, it would salivate (ucr). Over a number of trials, the bell and the (cs) is run just before the food is delivered.
