Chapter 8 - Flashcards
associative learning
Learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or response and its consequences (as an operant conditioning)
classical conditioning
A type of learning in which an organism comes to associate stimuli. A neutral stimulus that signals an unconditioned stimulus (US) begins to produce a response that anticipates and prepares for the unconditioned stimulus. Also called Pavlovian or respondent conditioning
Behaviorism
The view that psychology (1) should be an objective science that (2) Studies behavior without reference to mental processes. most research psychologist today agree with one but not with two
unconditioned response (UR)
in classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food is in the mouth
unconditioned stimulus (US)
in classical conditioning, a stimulus that unconditionally – naturally and automatically – triggers a response
conditioned response (CR)
in classical conditioning, the learned response to a previously neutral (but now conditioned) stimulus (CS)
conditioned stimulus (CS)
in classical conditioning, and originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response
acquisition
The initial stage in classical conditioning; the phase associating a neutral stimulus with an unconditioned stimulus so that the neutral stimulus comes to elicit a conditioned response. In operant conditioning, the strengthening of a reinforced response
extinction
The diminishing of a conditioned response; occurs in a classical conditioning when an unconditioned stimulus does not follow a conditioned stimulus; occurs in operant conditioning 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 elicit the same responses
discrimination
in classical conditioning, 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 behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
respondent behavior
behavior that occurs as an automatic response to some stimulus; Skinners term for behavior learned through classical conditioning
operant behavior
behavior that operates on the environment, producing consequences
law of effect
Thorndike’s principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely
operant chamber
The chamber also known as a skinner box, containing a bar or key that an animal can manipulate to obtain a food or water reinforcer, with attached devices to record the animals rate of bar pressing or key packing. Used in operant conditioning research
shaping
in operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
reinforcer
in operant conditioning, any event that strengthens the behavior it follows
positive reinforcement
increasing behaviors by presenting positive stimuli, such as food. A positive reinforcer is any stimulus that, when presented after response, strengthens the response
negative reinforcement
increasing behaviors by stopping or reducing negative stimuli, such as shock. The negative reinforcer is any stimulus that, when removed after response, strengthens the response. (Note: negative reinforcement is not punishment).
primary reinforcer
an innately reinforcing stimulus, such as one that satisfies a biological need
conditioned reinforcer
A stimulus that gains it’s reinforcing power through its association with a primary reinforcer; also known as secondary reinforcer
continuous reinforcement
reinforcing the desired response every time it occurs
