Learning
the process of acquiring new and relatively enduring information or behaviours
Habituation
an organism’s decreasing response to a stimulus with repeated exposure to it
Stimulus
any event or situation that evokes a response
Classical Conditioning
a type of learning in which one learns to link two or more stimuli and anticipate events
Neutral Stimulus
a stimulus that elicits no response before conditioning
Unconditioned Response
an unlearned, naturally occurring response to an unconditioned stimulus
Unconditioned Stimulus
a stimulus that unconditionally-naturally and automatically-triggers a response
Conditioned Response
a learned response to a previously neutral (but now conditioned) stimulus
Conditioned Stimulus
an originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response
Acquisition
when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response; the strengthening of a reinforced response
Extinction
the diminishing of a conditioned response; occurs when an unconditioned stimulus does not follow a conditioned stimulus; occurs when a response is no longer reinforced
Spontaneous Recovery
the reappearance, after a pause, of an extinguished conditioned response
Generalization
the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elect similar responses
Discrimination
the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus
Operant Conditioning
a type of learning in which behaviour is strengthened if followed by a reinforcer or diminished if followed by a punisher
Law of Effect
Thorndike’s principle that behaviours followed by favourable consequences become more likely, and that behaviours followed by unfavourable consequences become less likely
Reinforcement
any event that strengthens the behaviour it follows
Shaping
an operant conditioning procedure in which reinforcers guide behaviours toward closer and closer approximations of the desired behaviour
Discriminative Stimulus
a stimulus that elicits a response after association with reinforcement
Positive Reinforcement
increasing behaviours by presenting positive reinforcers
