Chapter 5: Learning and Behaviour Habituation modifying behaviour to fit environment = a form of learning assumption: all the new things we learn are built upon lower things lowest of the low is basic stimulus responses that we are born with (ex. Food in your mouth, your whole digestive system starts up) were interested in the association between the stimulus and response Conditioned: something that is learned Unconditioned: something that we didnt have to learn (inate, born with) Habituation: simplest form of learning; learning not to respond to an unimportant event that occurs repeatedly ex. getting used to something, learning to ignore it makes sense from an evolutionary perspective: paying attention to useless things is a waste of time and energy 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: process by which a response normally elicited by one stimulus (the UCS) comes to be controlled by another stimulus (CS) ex. Pavlovs 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. This is where the learning takes place. After a number of conditioning trials, if the CS is presented alone without the food, it will typically lead to a CR (salivating). Now, there is a link between salivation and the bell (CS). Unconditioned Stimulus: (UCS) a stimulus (food) that naturally elicits a reflexive behaviour (salvation) Unconditioned Response (UCR): a response, (salivation) that is elicited by the UCS (food) Conditional Stimulus: a stimulus that, due to its repeated association with a UCS, eventually elicits a CR (bell) Conditional Response: (CR) response elicited by CS (salivation) two functions f classical conditioning: (1) built ability to learn to recognize stimuli that predict occurrence of an important event; learner can make appropriate response faster 1 www.notesolution.com
