Term
Habituation
Definition
Learning not to respond to stimulation (simplest form of learning)
Term
Learning
Definition
Relatively permanent change in behavior and mental processes due to experience
Term
Mere Exposure Effect
Definition
Learned preference for stimuli we've been previously exposed to
Term
Operant Conditioning
Definition
Based on consequences of behavior, such as rewards and punishments, influence the probability that the behavior is repeated
Term
Trial-and-Error Learning
Definition
(Mouse->maze) Learner gradually learns the correct response by attempting many behaviors and noting which ones produce the desired consequence
Term
Classical Conditioning
Definition
A stimulus that produces an innate relex that becomes associated with a previously neutral stimulus. (What happens before something happens)
Term
Extinction
Definition
Weakening association in the absence of an unconditioned stimulus (ringing the bell without bringing food)
Term
Spontaneous Recovery
Definition
Relearning or remembering the associations (Weaker than in acquisition, but stronger than extinction)
Term
Acquisition
Definition
(Process of learning) Initial stage in classical conditioning (Pairing the NS with the UCS = CR)
Term
Unconditioned Stimulus
Definition
Anything that triggers a biological reaction (unconditioned response)[Puff of air->blink] [Food->dog salivates]

Stimulus Discrimination
Definition
Behaving differently with similar conditioned stimulus
Term
Neutral Stimulus
Definition
Any stimulus that produces no conditioned response prior to learning (The bell)
Term
B.F. Skinner
Definition
(Behaviorism)"The power of reinforcement" (Mouse->box) [Radical Behaviorist]
Term
Positive Reinforcement
Definition
Adding a pleasant stimulus so the behavior will happen again [Tell dog to sit, if he sits, he gets a treat]
Term
Negative Reinforcement
Definition
Remove an unpleasant stimulus to continue a behavior (Annoying bell when you don't put on your seatbelt)
Term
Continuous Reinforcement
Definition
All correct responses are reinforced
Term
Partial (Intermittent) Reinforcement
Definition
Responses are only sometimes reinforced (Slot machines)
Term
Ratio Schedules
Definition
Reinforcement depends on number of correct responses (Set number to attain reinforcer)
Term
Interval Schedules
Definition
Reinforcement depends on timed interval that has elapsed
Term
Fixed Ratio
Definition
Rewards appear after a certain set number of responses
Term
Variable Ratio
Definition
Unpredictable; rewards after a certain number of responses, but number varies from trial to trial
Term
Fixed Interval
Definition
Certain amount of time; rewards appear regardless of number of responses (Paycheck)
Term
Variable Interval
Definition
(Tremendous resistance to extinguishment) Rewards appear after a certain amount of time, but that amount of time varies trial to trial (Fishing)
Term
Primary Reinforcers
Definition
Non-learned, satisfy physiological need (Food, water, etc.(
Term
Secondary Reinforcers
Definition
Learned (Grades, praise and approval)
Term
Instinctive Drift
Definition
Innate response tendencies interfere with learned behaviors; innate tendencies can override behaviors learned through environment (cats clawing)
Term
Premack Principle
Definition
Reinforce low frequency response; a preferred activity can reinforce a less preferred activity (if children finish homework, they can go outside and play with friends)
Term
Punishment
Definition
(Goal: Diminish/stop behavior) Different from negative reinforcement
Term
Positive Punishment
Definition
Adding aversive stimulus after a response (Kicking/spanking a cat when it misbehaves)
Term
Negative Punishment
Definition
Removing attractive stimuls after a response (Taking video game away after misbehavior)
Term
Positive Reinforcement
Definition
Add bonus; encourages desirable behaviors
Term
Negative Reinforcement
Definition
Take aspirin, removes headache
Term
Insight Learning
Definition
[Kohler] Problem-solving occurs by suddenly perceiving new forms or relationships (Monkey->crates->bananas) [Lightbulb Moment]
Term
Cognitive Maps
Definition
A mental image used to navigate through a familiar environment [Thinking of how many window are in your house; "Is there a Dillard's in Lynnhaven Mall?" "Yes."]
Term
Latent Learning
Definition
Learning without reinforcement (Blank keyboard->fill it out)
Term
Behaviorism
Definition
Rewards and punishments only impact an individual; it works on the person watching and receiving (Albert Bandura)
Term
Observational Learning
Definition
Acquire new responses after watching others' behaviors
Term
Long-term Potentiation
Definition
Physical changes strengthen synapses; neurons fire rapidly; once we've learned it, the firing slows down
Term
Memory
Definition
Active cognitive system (stores, organizes, alters and retrieves information)Basic Functions->Encode, Store, and Retrieval
Term
Elaboration
Definition
Adding meaning to encoded information so it's more easily stored and retrieved
Term
Storage
Definition
Retention of encoded info over time
Term
Access and Retrieval
Definition
Involves location and recovery of information
Term
Icon
Definition
Fleeting image
Term
Echo
Definition
Fleeting sound
Term
Sensory Memory
Definition
Preserves brief sensory impressions of stimuli, also called sensory register
Term
Working Memory
Definition
(Also referred to as Short Term Memory) Sketchpad; preserves recently perceived events or experiences briefly (phonetically--based on sound)
Term
Chunking
Definition
CIAFBIMTVRCACBS (Breaking information into smaller, meaningful units)
Term
Elaborate Rehearsal
Definition
New info, connect with long-term info
Term
Level-of-processing Theory
Definition
The more thoroughly you connect new information with what you already know, the better you'll remember it.
Term
Long-Term Memory
Definition
Storehouse of knowledge; limitless, stores material organized according to meaning
Term
Procedural Memory
Definition
Storage of information regarding skills (Typing, riding a bike, etc.)
Term
Declarative Memory
Definition
Store factual information (dates) [Amnesia patients lose this]
Term
Episodic Memory
Definition
Subdivision of declarative; stores memories for personal events, times, and places (Graduation)
Term
Semantic Memory
Definition
Subdivision of declarative, impersonal facts; general knowledge [12 months in a year]
Term

Term
Encoding Specificity Principle
Definition
Memory is encoded and stored with specific cues in the context it was formed (Seeing professor in the grocery store in sweats with three children; it takes a minute to recognize her)

Term
Primary Effect
Definition
Relative ease of remembering first items (last items)

Definition
Forgetting caused by shifting attention elsewhere (retrieval issue) ["Where are my keys?"]
