sensory memory
|
holds a large amount of perceptual inpput for a very brief time, typically less then one second
|
|
short term memory
|
memory that holds relatively little information (5-9 items) for as long as 30 seconds
|
|
long term memory
|
memory store that holds a huge amount of information for a long time. (hours, years)
|
|
codes
|
a type of mental representation, an internal "representation" of a stimulus or event.
|
|
verbal code
|
verbal description of visual
|
|
visual code
|
visualization of verbal description
|
|
consolidation
|
process of converting information stored dynamically in LTM, into structural change in the brain
-hippocampus involved |
|
primary effect
|
increased memory for the first few stimuli, reflecting storage information on the LTM
|
|
recency effect
|
increased memory for the last few stimuli in a set, reflecting storage on the STM
|
|
Unconditioned Stimulus
|
A stimulus that elicits an automatic response, without requiring prior learning
ex- food. |
|
conditioned response
|
A response that depends, or that is conditional on pairing of the conditioned stimulus with an unconditioned stimulus; once learned, the conditioned response occurs when the conditioned stimulus is presented alone.
|
|
conditioned stimulus
|
An originally neutral stimulus that acquires significance through pairings with an unconditioned stimulus
ex- tone |
|
unconditioned response
|
the reflexive response elicited by a particular stimulus
ex salavation |
|
Acquisition
|
in classical conditioning, the initial learning of the conditioned response. (obtaining the imposed/direct behavior)
|
|
Extinction
|
“unpairing” of the Conditioned Stimulus and the Unconditioned Stimulus.
|
|
spontaneous recovery
|
The process of extinction is achieved by repeatedly giving the conditioned stimulus (tone) without the unconditioned stimulus (food)
|
|
Operant conditioning
|
Process by which behavior becomes associated with its consequences. Includes voluntary behavior such as generalization, discrimination, and extinction. Includes Stimulus, response, and consequence.
|
|
Classical conditioning
|
A type of learning that occurs when neutral stimulus becomes paired (associated) with a stimulus that causes a reflexive behavior and, in time, is sufficient enough to produce that behavior
|
|
Punishment
|
decrease the likelihood that a certain behavior will occur.
|
|
Reinforcement
|
increase likelihood that a certain behavior will occur.
|
|
Positive Reinforcement
|
Occurs when a desired reinforcer is presented after a behavior, thereby increasing the likelihood of a recurrence of that behavior. (reinforcer is given after good behavior)
|
|
Negative Reinforcement
|
Occurs when an unpleasant event or circumstance is removed, thereby increasing the likelihood of a recurrence of the behavior. (bad event or action that was given prior to behavior is removed, in hope of continuous behavior)
|
|
Negative Punishment
|
Occurs when a behavior leads to the removal of a pleasant event or circumstance, thereby decreasing the likelihood of a recurrence of the behavior. (Removal of pleasant event or circumstance to decrease repetition of that behavior)
|
|
Positive Punishment
|
Occurs when a behavior leads to an undesired consequence, thereby decreasing the likelihood of a recurrence of that behavior. (Behavior produces undesired consequence, to decrease reoccurrence of that behavior.)
|
|
Generalization
|
ability to emit a learned behavior in response to a similar stimulus. Ex- child learns to wipe nose on tissue, may then wipe nose on anything else that may resemble a tissue, such as cloth, sleeve, etc.
|
|
Discrimination
|
ability to engage in a learned behavior in response to a particular stimulus but not in response to a similar one. (punishment or reinforcement for certain objects. Child is reinforced when using tissue, rather then using a sleeve)
|
|
Successive approximations
|
series of smaller behavior involved in shaping a complex behavior
|
|
Shaping
|
gradual process of reinforcing an organism for behavior that gets closer and closer to the behavior you wish to produce.
|
|
Fixed Interval
|
reinforcement schedule in which reinforcement is given for a response emitted after a variable interval of time.(reinforcement given on a strict schedule ex- every 10 minutes)
|
|
Variable interval schedule
|
reinforcement schedule in which reinforcement is given after a variable interval of time (given randomly, rather than every 10 minutes.)
|
|
Fixed Ratio
|
Reinforcement schedule in which reinforcement is given after a fixed number of responses.
|
|
Variable Ratio
|
Reinforcement schedule in which reinforcement is given after a variable number of responces
|
|
Schedules
|
can be continuous or partial; if partial reinforcement can be given based on after an interval of time (interval scheduling) or based on emitted responces (ration scheduling).
|
|
Cognitive learning
|
acquisition of information that often is not immediately acted on but stored for later use. Ex- planning, evaluating, and other forms of thinking, but not acted on immediately)
|
|
Latent learning
|
occurs without behavioral signs, and
|
|
Insight learning
|
occurs when a person or animal suddenly grasps what something means and incorporates that new knowledge into old knowledge. Ex- “ah-ha” experience.
|
|
Social (observational) learning
|
that occurs through watching others, not through reinforcement.
