TEST 2 (UNITS 5 - 7) Flashcards
any event or object in the environment to which an organism responds
STIMULUS
a relatively permanent change in behaviour, capability or attitude that is acquired through experience and cannot be attributed to illness, injury or maturation
LEARNING
a process through which a response previously made only to a specific stimulus is made to another stimulus that has been paired repeatedly with the original stimulus
CLASSICAL CONDITIONING
a stimulus that elicits a specific response without prior learning; eg. food
UNCONDITIONED STIMULUS
a response that is invariably elicited by the unconditioned stimulus without prior learning; eg. salivation in response to food
UNCONDITIONED RESPONSE
a neutral stimulus that, after repeated pairing with an unconditioned stimulus, becomes associated with it and elects a conditioned response; eg. the tone
CONDITIONED STIMULUS
a response that comes to be elicited by a conditioned stimulus as a result of its repeated pairing with an unconditioned stimulus; eg. salivation in response to the tone
CONDITIONED RESPONSE
DEFINITION: the weakening and often eventual disappearance of learned response, by repeated presentation of the conditioned stimulus without the unconditioned stimulus
EXAMPLE:
EXTINCTION
DEFINITION: the reappearance of an extinguished response (in a weaker form) when an organism is exposed to the original conditioned stimulus following a rest period.
EXAMPLE:
SPONTANEOUS RECOVERY
DEFINITION: in classical conditioning, the tendency to make a conditioned response to a stimulus that is similar to the original conditioned stimulus
EXAMPLE: a child attacked by a dog can easily develop a long-lasting fear of all dogs
GENERALIZATION
DEFINITION: the learned ability to distinguish between similar stimuli so that the conditioned response occurs only to the original conditioned stimulus but not to similar stimuli
EXAMPLE: this ability has survival value in that we know the difference between a rattlesnake and a garter snake
DISCRIMINATION
DEFINITION: occurs when a neutral stimulus is paired with an existing conditioned stimulus, becomes associated with it, and gains the power to elicit the same conditioned response
EXAMPLE: Suppose that after Pavlov conditioned the dogs to salivate to a tone, he presented a light (neutral stimulus) immediately before the tone a number of times. The light would become associated with the tone, and the dogs would learn to give the salivation response to the light alone.
higher-order conditioning
PRINCIPLE OF WHAT?
a type of learning in which the consequences of behaviour tend to modify that behaviour in the future (behaviour that is reinforced tends to be repeated; behaviour that is ignored or punished is less likely to be repeated).
OPERANT CONDITIONING
PRINCIPLE OF WHAT?
the consequences of behaviour are manipulated to increase or decrease the frequency of a response or to shape an entirely new response.
OPERANT CONDITIONING
DEFINITION: technique that reinforces any movement in the direction of the desired response, and gradually guiding the responses closer and closer to the ultimate goal
EXAMPLE: eg. Even though the B that Billy wrote looked more like a D, his teacher, Mrs. Chen, praised him because it was better than his previous attempts. Mrs. Chen is using a procedure called shaping.
SHAPING
POSITIVE OR NEGATIVE REINFORCEMENT?
a reward or pleasant consequence that follows a response and increases the probability that the response will be repeated
- eg. salary raises, promotions, awards, bonuses, good grades, and candy
POSITIVE
POSITIVE OR NEGATIVE REINFORCEMENT? the termination of an unpleasant stimulus after a response in order to increase the probability that the response will be repeated
- eg. turning on one’s air conditioner to terminate heat or getting out of bed to turn off a faucet to avoid listening to the annoying “drip, drip, drip.”
NEGATIVE
Differentiate between primary reinforcers and secondary reinforcers and examples of each kind
primary reinforcer: reinforcer that fulfills a basic physical need for survival and does not depend on learning; EG. food, water, sleep, sex, and the termination of pain
secondary reinforcer: neutral stimulus that becomes reinforcing after repeated pairing with other reinforcers; EG. attention from others is a powerful type of this reinforcer
4 factors that influence operant conditioning:
- magnitude of reinforcement
- immediacy of reinforcement
- level of motivation
- schedule of reinforcement
3 factors that influence the effectiveness of punishment
- timing of application
- intensity of application
- consistency of application
Compare and contrast classical and operant conditioning:
In classical conditioning, the focus is on what precedes the response. In operant conditioning, the focus is on what follows the response.
- Generally, in classical conditioning, the subject is passive and responds to the environment rather than acting upon it. In operant conditioning, the subject is active and operates on the environment.
