Learning and Conditioning Vocab Flashcards
the process of acquiring through experience new and relatively enduring information or behaviors
ex: knowing not to do a behavior after being negatively punished
learning
decreasing responsiveness with repeated exposure to a stimulus
ex: a squirt of water causes a sea slug to withdraw its gills; if the water repeatedly squirts, eventually the slug will not withdraw its gills (it gets used to it)
habituation
learning that certain events occur together; the events may be two stimuli (as in classical conditioning) or a response and its consequence (as in operant conditioning)
ex: the sea slug associates the squirt with an impending shock (if it is shocked after the squirt of water, its response grows stronger)
associative learning
any event or situation that evokes a response
ex: we learn a flash of lightning signals an impending crack of thunder
stimulus
behavior that occurs as an automatic response to some stimulus
ex: when lightning flashes, we start to brace ourselves
respondent behavior
behavior that operates on the environment, producing consequences
ex: a child uses good manners and gets rewarded, therefore they become a well-mannered adult
operant behavior
the acquisition of mental information, whether by observing events, by watching others, or through language
ex: chimpanzees learn behaviors by watching others perform
cognitive learning
a type of learning in which we link two or more stimuli; as a result, to illustrate with Pavlov’s classic experiment, the first stimulus (a tone) comes to elicit behavior (drooling) in anticipation of the second stimulus (food)
ex: dog associates a tone with food
classical conditioning
the view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes; most research psychologists today agree with (1) but not with (2)
ex: Watson hated mentalistic concepts and thought that all references to inner thoughts, feelings, and motives should be discarded when it comes to psychology
behaviorism
in classical conditioning, a stimulus that elicits no response before conditioning
ex: when the tone is first presented to the dog it means nothing; eventually it makes the link between it and food
neutral stimulus (NS)
in classical conditioning, an unlearned, naturally occurring response (such as salivation) to an unconditioned stimulus (US) (such as food in the mouth)
unconditioned response (UR)
in classical conditioning, a stimulus that unconditionally-naturally and automatically-triggers an unconditioned response (UR)
ex: food to dog
unconditioned stimulus (US)
in classical conditioning, a learned response to a previously neutral (but now conditioned) stimulus (CS)
ex: dog eventually associates tone with food
conditioned response (CR)
in classical conditioning, an originally neutral stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response (CR)
ex: previously meaningless tone that now triggers salivation
conditioned stimulus (CS)
in classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response; in operant conditioning, the strengthening of a reinforced response
ex: research where repeatedly presenting a female quail and turning a red light on causes a male quail to become turned on just from the light (increasing reproduction)
acquisition
a procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus
ex: an animal that has learned that a tone predicts food might then learn that a light predicts the tone and begin responding to the light alone
higher-order conditioning (also called second-order conditioning)
the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced
ex: researchers stop playing the tone when presenting food
extinction
the reappearance, after a pause, of an extinguished conditioned response
ex: after a few hours, the researchers play tone again when presenting the food
spontaneous recovery
the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses; (in operant conditioning, this occurs when responses learned in one situation occur in other, similar situations)
ex: a slightly different tone is played to dogs when presenting food, they still give the conditioned response (drool); a toddler learns to fear moving cars, so they also fear trucks and motorcycles
generalization
in classical conditioning, the learned ability to distinguish between a conditioned stimulus and similar stimuli that do not signal an unconditioned stimulus; (in operant conditioning, the ability to distinguish responses that are reinforced from similar responses that are not reinforced)
ex: occasionally, a dog might distinguish the original tone from the slightly different tone
discrimination
a type of learning in which a behavior becomes more likely to recur if followed by a reinforcer or less likely to recur if followed by a punisher
ex: a parent gives their child a time out after the child was throwing tantrums
operant conditioning
Thorndike’s principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely
ex: if you work hard and receive a promotion, you will be more likely to continue putting in more effort
law of effect
in operant conditioning research, a chamber (also known as a Skinner box) containing a bar or a key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animal’s rate of bar pressing or key pecking
operant chamber
in operant conditioning, any event that strengthens the behavior it follows
ex: praise, attention, a paycheck
reinforcement
an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
ex: when a baby is learning to walk step by step
