Ch 3 Flashcards
Habituation
Process of becoming used to a stimulus
Dis habituation
Can occur when a second stimulus intervenes causing re-sensitization to the original stimulus
Associative learning
Way of pairing together stimuli and responses or behaviors and consequences
Classical conditioning
And unconditioned stimulus produces an instinctive unconditioned response is paired with a neutral stimulus. With repetition the neutral stimulus becomes a conditioned stimulus that produces a conditioned response
Unconditioned stimulus is a stimulus that brings reflex response
Neutral stimuli do not produce a reflexive response
Also called acquisition
In operant conditioning
Behaviors change through the use of consequences
Reinforcement
Increases the likelihood of the behavior
Punishment
Decreases the likelihood of A behavior
Positive punishment add an unpleasant consequence in response to a behavior
Negative punishment is the reduction of a behavior when a stimulus is removed
Schedule of reinforcement
Affects the rate at which the behavior is performed. Schedules can be based either on a ratio of behavior to reward or on an amount of time and can be either fixed or variable. Behaviors learned to variable ratio schedules are the hardest to is extinguish.
Encoding
Process of putting new information into memory. It can be automatic or effortful
Semantic encoding
Stronger than both acoustic and visual encoding
Sensory and short term memory
Transient and are based on neurotransmitter activity
7+ 2 rule
Located inhippocampus
Working memory
Require short term memory attention and executive function to manipulate information
Long term memory
Requires elaborate rehearsal and is the result of an increase neuronal connectivity
Explicit declarative memory
Stores facts and stories
Implicit non-declarative memory
Store skills and conditioning effects
Semantic networks
This is how facts are stored
Recognition versus recall
Recognition of information is stronger than recall
Retrieval of information
Based on priming interconnected nodes of the semantic network
How are memories lost
Alzheimer’s disease, Korsakoff syndrome, Agnocia, decay, interference
Neural plasticity
Decreases with age and both learning and memory rely on changes in brain chemistry and physiology which depends on this
