Document Summary
De nition of learning: as a relatively lasting change in behaviour that is the result of experience. Learning became a major focus of study in psychology during the early part of the twentieth century as behaviourism rose to become a major school of thought. Habituation and sensitization: habituation refers to decreases in responses by repeated presentation of a known stimulus; sensitization is the opposite and refers to increased responses, with both types of change resulting from previous experience. Both occur in many situations, but always require repeated exposure to a stimulus. Classical conditioning: a learning process that occurs when two stimuli are repeatedly paired; a response that is at rst elicited by the second stimulus is eventually elicited by the rst stimulus alone. Unconditioned stimulus: (ucs) is one that unconditionally, naturally, and automatically triggers a response. For example, when you smell one of your favourite foods, you may immediately feel very hungry.
