Term
Memory
Definition
Encode, store, receive. Constructed.

Encoding
Definition
The process by which we transform what we perceive, think, or feel into an enduring memory
Term

Term
Encoding Specificity
Definition
Retrieval is facilitated in environmental contexts similar to when info was encoded
Term
State Dependent retrieval

Term
Explicit Memory (Semantic, Episodic)
Definition
Consciously & intentionally retrieving information. Semantic: Facts/general knowledge. Episodic: Personally experienced events.
Term
Implicit Memory (Procedural, Priming)
Definition
Unconscious influence of past behavior. Procedural: Gradual acquisition of behavioral skills as a result of practice or learning. Priming: The automatic influence of recent information leading to biased retrieval, faster recognition of previously seen stimuli.
Term
Transience
Definition
Forgetting information with the passage of time. Loss of information levels off after 9 hours. Goes from specific to general
Term
Interference (Retroactive, Proactive)
Definition
Retro: Later learning impairs ability to recall previously learned info. Pro: Earlier learning impairs memory for info acquired later.

Term
Learning
Definition
A process that incolves some experience that results in a relative permanent change in the state of learner. Cannot be directly observed, learned is not the opposite of innate.
Term
Habituation
Definition
Repeated/prolongued exposure to a stimulus results in a gradual reuction in responding
Term

Term
Classical Conditioning (Ivan Pavlov)
Definition
A process of association in which a previous neutral stimulus elicits a new response

Term
Unconditioned Response (UR)
Definition
A reflexive reaction that is reliably elicited by an unconditioned stimulus
Term
Conditioned Stimulus (CS)
Definition
A stimulus that is initially neutral and produces no reliable response
Term
Conditioned Response (CR)
Definition
A reaction that resembles an unconditioned response but is produced by a conditioned stimulus
Term
Acquisition
Definition
Pairing of the CS and UR. Most effective when the US immediately follows CS
Term
Extinction
Definition
The gradual elimination of a learned response after the US is removed (CS only)
Term
Spontaneous Recovery
Definition
Tendency of a learned behavior to recover from extinction after a rest period
Term
Savings
Definition
If the CS/US are repaired after extinction, the CR is learned considerably faster than first acquisition
Term
Generalization

When the CR is observed in the context of a slightly different stimulus (CS)
Term
Discrimination
Definition
The ability to distinguish between similar but distint stimuli
Term
Little Albert
Definition
Presented with fuzzy animals (CS), paired with loud sounds (US). Soon the CS alone without the US was enough to produce his CR, a fearful reaction.
Term
Amygdala in Classical Conditioning
Definition
Allows you to experience fear/anxiety and form emotional memories.
Term
Cognition
Definition
Ability to acquire knowledge..conditioning is easier when conditioned stimulus is unfamiliar and without other associations
Term
Rescorla-Wagner Model
Definition
Familiarity with the stimulus hinders new conditioning. A child being present in the acquisition of a bad event doesn't cause parent to respond poorly to presence of child from then on
Term
Evolutionary adaptive process
Definition
Learned food aversions prevent poisoning..
Term
Evolutionary adaptive process
Definition
Learned food aversions prevent poisoning..
Term
Biological preparedness
Definition
A tendency for learning particular kinds of associations over others
Term
Operant Conditioning
Definition
A type of learning in which the consequences of an organism's behavior determine whether it will be repeated in the future
Term

Definition
Unpleasant stimulus is taken away
Term
Positive punishment
Definition
