Term | Definition |
---|---|
Learning | The process of acquiring through experience new and relatively enduring information or behaviors. |
Associative Learning | Learning that certain events occur together. |
Stimulus | Any event or situation that evokes a response. |
Respondent Behavior | Behavior that occurs as an automatic response to some stimulus. |
Operant Behavior | Behavior that operates on the environment, producing consequences. |
Cognitive Learning | We learn things we have neither experienced, nor learned. |
Classical Conditioning | We learn to expect and prepare for significant events such as food or pain. |
Behaviorism | A school of psychology that studies the behavior of humans and animals based on observable, measurable, and quantitative events. |
Neutral Stimulus | A stimulus which does not innately evoke a response. |
Unconditioned Response | An unlearned response that occurs naturally in reaction to the unconditioned stimulus. |
Unconditioned Stimulus | A stimulus that leads to an automatic response without prior learning. |
Conditioned Response | A learned response to a previously neutral stimulus that occurs after conditioning. |
Conditioned Stimulus | A previously neutral stimulus that eventually triggers a conditioned response. |
Acquisition | Classical conditioning: creating the initial association. Operant Conditioning: strengthening of a reinforced response or decreasing of a punished response |
Extinction | When an unconditioned stimulus does not follow a conditioned stimulus. |
Spontaneous Recovery | The reappearance, after a pause, of as extinguished conditioned response. |
Generalization | The tendency for stimuli similar to the conditioned stimulus to elicit similar responses. |
Discrimination | The learned ability to distinguish between a conditioned stimulus and similar stimuli that do not signal to an unconditioned stimulus. |
Operant conditioning | We learn to repeat acts that bring rewards and avoid acts that bring unwanted results. |
Reinforcement | gradual modification of synaptic properties that occurs during learning. |
Positive Reinforcement | Any stimulus that, when presented after a response, strengthens the response. |
Negative Reinforcement | Any stimulus that, when removed after a response, strengthens the response. |
Primary Reinforcer | Innately reinforcing stimuli such as those that satisfy a biological need. |
Conditioned Reinforcer | Stimuli that gain their reinforcing power through their learned association with a primary reinforcer. |
Reinforcement Schedule | Patterns that define how often a certain desired response will be reinforced. |
Punishment | An event that tends to decrease the behavior it follows. Behavior that is punished is less likely to occur again. |
