Chapter 7 Learning; Vocab
| Term | Definition |
|---|---|
| Learning | The acquisition, from experience, of new knowledge, skills, or responses that results in a relatively permanent change in the state of the learner. |
| Habituation | A general process in which repeated or prolonged exposure to a stimulus results in a gradual reduction in responding |
| Sensitization | A simple form of learning that occurs when presentation of a stimulus leads to an increased response to a later stimulus |
| Classical Conditioning | A type of learning that occurs when a neutral stimulus produces a response after being paired with a stimulus that naturally produces a response |
| Unconditioned Stimulus (US) | Something that reliably produces a naturally occurring reaction in an organism |
| Unconditioned Response (UR) | A reflexive reaction that is reliably produced by an unconditioned response |
| Acquisition | The phase of classical conditioning when the conditioned stimulus (CS) and the unconditioned stimulus (US) are presented together |
| Conditioned Stimulus (CS) | A previously neutral stimulus that produces a reliable response in an organism after being paired with an unconditioned stimulus (US) |
| Conditioned Response (CR) | A reaction that resembles an unconditioned responses but is produced by a conditioned stimulus (CS) |
| Second-Order Conditioning | A type of learning where a conditioned stimulus (CS) is paired with a stimulus that became associated with the unconditioned stimulus (US) in an earlier procedure |
| Extinction | The gradual elimination of a learned response that occurs when the conditioned stimulus (CS) is repeatedly presented without the unconditioned stimulus (US) |
| Spontaneous Recovery | The tendency of a learned behavior to recover from extinction after a rest period |
| Generalization | The conditioned response (CR) is observed even though the conditioned stimulus (CS) is slightly different from the conditioned stimulus (CS) used during acquisition |
| Discrimination | The capacity to distinguish between similar but distinct stimuli |
| Biological Preparedness | A propensity for learning particular kinds of association over others |
| Operant Conditioning | A type of learning in which the consequences of an organism's behavior determine whether it will repeat that behavior in the future |
| Law of Effect | The principle that behaviors that are followed by a "satisfying state of affairs" tend to be repeated, and those that produce an "unpleasant state of affairs" are less likely to be repeated |
| Operant Behavior | Behavior that an organism performs that has some impact on the environment |
| Reinforcer | Any stimulus or event that increases the likelihood of the behavior that led to it |
| Punisher | Any stimulus or event that decreases the likelihood of the behavior that led to it |
| Fixed-Interval Schedule (FI) | An operant conditioning principle whereby reinforcers are presented at fixed time periods, provided that the appropriate response is made |
| Variable-Interval Schedule (VI) | An operant conditioning principle whereby behavior is reinforced on the basis of an average time that has expired since the last reinforcement |
| Fixed-Ratio Schedule (FR) | An operant conditioning principle whereby reinforcement is delivered after a specific number of responses have been made |
| Variable-Ratio Schedule (VR) | An operant conditioning principle whereby the delivery of reinforcement is based on a particular average number of responses |
| Intermittent Reinforcement | An operant conditioning principle whereby only some of the responses made are followed by reinforcement |
| Intermittent Reinforcement Effect | The fact that operant behaviors that are maintained under intermittent reinforcement schedules resist extinction better than those maintained under continuous reinforcement |
| Shaping | Learning that results from the reinforcement of successive steps to a final desired behavior |
| Latent Learning | A process in which something is learned, but it is not manifested as a behavioral change until sometime in the future |
| Cognitive Map | A mental representation of the physical features of the environment |
| Observational Learning | A condition in which an organism learns by watching the actions of others |
| Diffusion Chain | A process in which individuals initially learn a behavior by observing another individual perform that behavior, and then become models from which other individuals learn the behaviors |
| Implicit Learning | Learning that takes place largely independent of awareness of both the process and the products of information of acquisition |
