Learning
Term | Definition |
---|---|
Learning | The process of acquiring new and relatively enduring information or behaviors. |
Habituates | An organism's decreasing response to a stimulus with repeated exposure to it. |
Associative Learning | Learning that certain events occur together. The events may be 2 stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning) |
Stimulus | Any event of situation that evokes a response. |
Cognitive Learning | The acquisition of mental information, wether by observing events, by watching others, or through language. |
Classical Conditioning | A type of learning in which one learns to link two or more stimuli and anticipate events. (discovered by Ivan Parlov) |
Behavioralism | 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 (2). |
Neutral Stimuli (NS) | In classical conditioning, a stimulus that elicits no response before conditioning. |
Unconditioned Response (UR) | In classical conditioning, an unlearned, naturally occurring response (such as salivation) to an unconditioned stimulus (US) (such as food in the mouth). |
Unconditioned Stimulus (US) | In classical conditioning, a stimulus that unconditionally - naturally and automatically - triggers a response (UR). |
Conditioned Response (CR) | In classical conditioning, a learned response to a previously neutral (but now conditioned) stimulus (CS). |
Conditioned Stimulus (CS) | In classical conditioning, an originally irrelevant stimulus that, after association, with an unconditioned stimulus (US), comes to trigger a conditioned response (CR). |
Acquisition | 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. |
Higher-order conditioning | A procedure in which the conditioned stimulus in one conditioning experience is paired with a neutral stimulus creating a second (often weaker) conditioned stimulus. |
Extinction | The diminishing of a conditioned response, occurs in classical conditioning when a unconditioned stimulus (US) does not follow a conditioned stimulus (CS); 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 a stimuli similar to the conditioned stimulus to elicit a similar response. |
Discrimination | In classical conditioning, the learned ability to distinguish between a conditioned stimulus and a stimuli that does 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. |
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 | In operant conditioning research, a chamber (skinner box) containing a bar or a key that an animal can manipulate to obtain food or water reinforcers; attached devices record the animal's rate of bar pressing or key pecking. |
Reinforcement | In operant conditioning, any event that strengthens the behavior it follows. |
Shaping | An operant conditioning procedure in which reinforcers guide behavior towards closer and closer approximations of the desired behavior. |
Discriminative Stimulus | In operant conditioning, a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reward) |
Positive Reinforcement | Increasing behaviors by presenting positive reinforcers. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response. |
Negative Reinforcement | Increasing behaviors by stopping or reducing negative stimuli. A negative reinforcer is any stimulus that when removed after a response, strengthens the response. (it is not a punishment) |
Primary Reinforcer | A innately reinforcing stimulus, such as one that satisfies a biological need (unlearned). |
Conditioning Reinforcer | A stimulus that gains its reinforcing power through its association with a primary reinforcer; also known as a secondary reinforcer (learned). |
Reinforcement Schedule | A pattern that defines how often a desired response will be reinforced. |
Continuous Reinforcement | Reinforcing the desired response every time it occurs. |
Partial (Intermittent) Reinforcement | Reinforcing a response only part of the time; results in a slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement. |
Fixed-Ratio Schedule | In operant conditioning, a reinforcement schedule that reinforces a response only after a specific number of responses. |
Variable-Ratio Schedule | In operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses. |
Fixed-Interval Schedule | In operant conditioning, a reinforcement schedule that reinforces a response only after a specific time has elapsed. |
Variable-Interval Schedule | In operant conditioning, a reinforcement schedule that reinforces a response at unpredictable time intervals. |
Punishment | An event that tends to decrease the behavior that it follows. |
Biofeedback | A system of electronically recording, amplifying, and feeding back information regarding a subtle physiological state, such as blood pressure or muscle tension. |
Respondent Behavior | (Classical) Behavior that occurs as an automatic response to some stimulus. |
Operant Behavior | (Operant) Behavior that operates on the environment, producing consequences. |
Cognitive Map | A mental representation of the layout of one's environment. |
Latent Learning | Learning that occurs but is not apparent until there is an incentive to demonstrate it. |
Insight | A sudden realization of a problem's solution. |
Intrinsic Motivation | A desire to preform a behavior effectively for its own sake. |
Extrinsic Motivation | A desire to preform a behavior to receive promised rewards or avoid threatened punishment. |
Coping | Alleviating stress using emotional, cognitive, or behavioral methods. |
Problem-Focused Coping | Attempting to alleviate stress directly -- by changing the stressor or the way we interact with that stressor. |
Emotion-Focused Coping | Attempting to alleviate stress by avoiding or ignoring a stressor and attending to emotional needs related to one's stress reaction. |
Learned Helplessness | The hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events. |
External Locus of Control | The perception that chance or outside forces beyond our personal control determine our fate. |
Internal Locus of Control | The perception that you control your own fate. |
Self-Control | The ability to control impulses and delay short-term gratification for greater long-term rewards. |
Observational Learning | Learning by observing others. Also called social learning. |
Modeling | The process of observing and imitating a specific behavior. |
Mirror Neurons | Frontal lobe neurons that some scientists believe fire when preforming certain actions or when observing another doing so. The brain's mirror of another's action may enable imitation and empathy. |
Prosocial Behavior | Positive, constructive, helpful behavior. The opposite of antisocial behavior. |
