Midterm 2 Flashcards
Learning can be described as
a process by which behaviour or knowledge changes as a result of experience
_______ is learning that occurs when a neutral stimulus elicits a response that was originally caused by another stimulus
Classical Conditioning
Unconditioned stimulus
a stimulus that elicits a reflexive response without learning
Unconditioned response
A reflexive, unlearned reaction to an unconditioned stimulus
_____ can be described as a once neutral stimulus that later elicits a conditioned response
Conditioned stimulus
_______ can be described as the learned response that occurs to the conditioned stimulus
Conditioned response
Acquisition is when
the initial phase of learning in which a response is established
______ is the loss or weakening of a conditioned response when a conditioned stimulus and unconditioned stimulus no longer occur together
Extinction
Spontaneous recovery is when
the recurrence of a previously extinguished conditioned response typically after some time has passed since extinction
_____ is a process in which a response that originally occurs to a specific stimulus also occurs to a different though similar stimulus
generalization
Discrimination can be described as
an organism learns to respond one original stimulus but not to a new stimulus even though it could be similar
Conditioned emotional Response
consists of emotional and physiological responses that develop to a specific object or situation
_____ is the biological predisposition to rapidly learn a response to a particular class of stimuli
preparedness
______ acquired dislike disgust of a food or drink because it was paired with an illness
Conditioned taste aversion
Conditioned drug tolerance
over time more drug is needed achieve the same high
Operant conditioning is a
type of learning in which behaviour is influenced by consequences
Reinforcement is a
process in which an event or reward follows a response which increases that the behaviour will occur again
Punishment is a
process that decreases the future probability of a response
a stimulus that is contingent upon a response that increases the probability of that response occurring again
reinforcer
a stimulus that is contingent upon a response that results in a decrease in a behaviour
punisher
Positive reinforcement is
the strengthening of behaviour after potential reinforcers such as praise or money follow that behaviour
Negative Reinforcement involves
The strengthening of a behaviour because it removes or diminishes a stimulus
_____ is a specific type of negative reinforcement that removes the possibility that a stimulus will occur
avoidance learning
Escape learning is when
a response is removes a stimulus that is already present
Positive Punishment
A process in which a behaviour decreases in frequency because it was followed by a particular usually unpleasant stimulus
Negative punishment
occurs when a behaviour decreases because it removes or diminishes a particular stimulus
Primary reinforcers consist of
reinforcing stimuli that satisfy basic motivational needs that affect an individual’s ability to survive
Secondary Reinforcers consist of
stimuli that acquire their reinforcing effects only after we learn they have value
_______ is a cue or event that indicates that a response if made will be reinforced
discriminative stimulus
Extinction
The weakening of an operant response when reinforcement is no longer available
Shaping
a procedure in which a specific operant response is created by reinforcing successive approximation of that response
______ can be described as rules that determine when reinforcement is available
Schedules of Reinforcement
_____ is when every response results in reinforcement
Continuous Reinforcement
Partial Reinforcement is
only a certain number of responses are rewarded or a certain amount of time must pass before reinforcement is available
Fixed ratio schedule
reinforcement is delivered after a specific number of responses have been completed
Variable ratio schedule
the number of responses required to receive reinforcement varies according to an average age
Fixed interval schedule
Reinforces the first response occurring after a set amount of time passes
Variable interval schedule
The first response is reinforced following a variable amount of time
Partial Reinforcement Effect
A phenomenon in which organisms that have been conditioned under partial reinforcement resist extinction longer than those conditioned under continuous
In operant conditioning, reinforcement is _______
a consequence of a behaviour
In Classical conditioning, reinforcement is _______
present regardless whether a response occurs
In classical conditioning behaviour mostly depends on
reflexive and psychological responses
In operant conditioning behaviour mostly depends on
skeletal muscles
Stores retain_______
information in memory without using it for any specific purpose
Control processes
shift information from one memory store into another
Attention
selects which information will be passed on to the short term memory
Encoding
The process of storing information information in the long term memory back into the short term memory
Retrieval
Brings information from the long term memory back into the short term memory
sensory memory
a memory store that accurately holds perceptual information for a very brief amount of time
Iconic Memory
The visual form of sensory memory
Echoic Memory
The auditory form of sensory memory
Short term memory
a memory store with limited capacity and duration (less than a min)
Long term memory
Holds information for an extended periods of times if not permanently
Chunking
Organizing smaller units of information into larger more meaningful units
Serial Position effect
Most people will recall the first few items in a list and the last few items and maybe 1-2 items from the middle
Proactive Interference
The first information learned occupies memory
Retroactive Interference
The most recently learned information overshadows some older memories that have not yet made it into long term memory
Storage
Refers to the time and manner in which information is retained between encoding and retrieval
Maintenance Rehearsal
Prolonging exposure to information by repeating it
Elaborative Rehearsal
Prolonging exposure to information by thinking about it’s meaning
Shallow processing
involves more superficial properties of a stimulus such as the sound of spelling of a word
