Learning and Memory
Vocabulary for Theme 4
Term | Definition |
---|---|
Classical Conditioning | A learning procedure in which associations are made between a natural stimulus and a neutral stimulus. |
Neutral Stimulus | A stimulus that does not initially elicit any part of the unconditioned response. |
Unconditioned Stimulus [UCS] | An event that elicits a certain predictable response typically without previous training. |
Unconditioned Response [UCR] | An organism's automatic [or natural] reaction to a stimulus. |
Conditioned Stimulus [CS] | A once-neutral event that elicits a given response after a period of training in which it has been paired with an unconditioned stimulus. |
Conditioned Response [CR] | The learned reaction to a conditioned stimulus. |
Generalization | Responding similarly to a range of similar stimuli. |
Discrimination | The ability to respond differently to similar but distinct stimuli. |
Extinction | The gradual disappearance of a conditioned response when the conditioned stimulus is repeatedly presented without the unconditioned stimulus. |
Operant Conditioning | Learning in which a certain action is reinforced or punished, resulting in corresponding increases or decreases in occurrence. |
Reinforcement | Stimulus or event that follows a response and increases the likelihood that the response will be repeated. |
Primary Reinforcer | Stimulus that is naturally rewarding, such as food or water. |
Secondary Reinforcer | Stimulus such as money that becomes rewarding through its link with a primary reinforcer. |
Fixed-Ratio Schedule | A pattern of reinforcement in which a specific number of correct responses is required before reinforcement can be obtained. |
Variable-Ratio Schedule | A pattern of reinforcement in which an unpredictable number of responses are required before reinforcement can be obtained. |
Fixed-Interval Schedule | A pattern of reinforcement in which a specific amount of time must elapse before a response will elicit reinforcement. |
Variable-Interval Schedule | A pattern of reinforcement in which changing amounts if time must elapse before a response will obtain reinforcement. |
Shaping | Technique in which the desired behavior is "molded" by first rewarding any act similar to that behavior and then requiring ever-closer approximations to the desired behavior before giving the reward. |
Response Chain | Learned reactions that follow one another in sequence, each reaction producing the signal for the next. |
Aversive Control | Process of influencing behavior by means of unpleasant stimuli. |
Negative Reinforcement | Increasing the strength of a given response by removing or preventing a painful stimulus when the response occurs. |
Escape Conditioning | Training of an organism to remove or terminate an unpleasant stimulus. |
Avoidance Conditioning | Training of an organism to withdraw from or prevent an unpleasant stimulus before it starts. |
Social Learning | Process of altering behavior by observing and imitating the behavior(s) of others. |
Cognitive Learning | Form of altering behavior that involves mental processes and may result from observation or imitation. |
Cognitive Map | A mental picture of spatial relationships between events. |
Latent Learning | Alteration of a behavioral tendency that is not demonstrated by an immediate, observable change in behavior. |
Learned Helplessness | Condition in which repeated attempts to control a situation fail, resulting in the belief that the situation is uncontrollable. |
Modeling | Learning by imitating others; copying behavior. |
Behavior Modification | Systematic application of learning principles to change people's actions and or feelings. |
Token Economy | Conditioning in which desirable behavior is reinforced with valueless objects, which can be accumulated and exchanged for valued rewards. |
Memory | The storage and retrieval of what has been learned or experienced. |
Encoding | The transforming of information so the nervous system can process it. |
Storage | The process by which information is maintained over a period of time. |
Retrieval | The process of obtaining information that has been stored in memory. |
Sensory Memory | Very brief memory storage immediately following the initial stimulation of a receptor. |
Short-Term Memory | Memory that is limited in capacity to about seven items and in duration by the subject's active rehearsal. |
Maintenance Rehearsal | A system for remembering that involves repeating information to oneself without attempting to find meaning in it. |
Chunking | The process of grouping items to make them easier to remember. |
Semantic Memory | Knowledge if language, including its rules, words, and meanings. |
Episodic Memory | Memory of one's life, including time of occurence. |
Declarative Memory | Memory of knowledge that can be called forth consciously as needed. |
Procedural Memory | Memory of learned skills that does not require conscious recollection. |
Recognition | Memory retrieval in which a person identifies an object, idea, or situation as one he or she has or has not experienced before. |
Recall | Memory retrieval in which a person reconstructs previously learned material. |
Reconstructive Processes | The alteration of a recalled memory that may be simplified, enriched, or distorted, depending on an individual's experiences, attitudes, or inferences. |
Confabulation | The act of filling in memory gaps. |
Schemas | Conceptual frameworks a person uses to make sense of the world. |
Eidetic Memory | The ability to remember with great accuracy visual information on the basis of short-term exposure. |
Decay | Fading away of memory over time. |
Interference | Blockage of a memory by previous or subsequent memories. |
Elaborative Rehearsal | The linking of new information to material that is already known. |
Mnemonic Devices | Techniques for using associations to memorize and retrieve information. |
