Unit 3 Flashcards
learning
Process of acquiring through experiencing new and relatively enduring information or behaviors
association
Naturally connecting events that happen in sequence
How do habits form
When behavior is repeating in a given context
On average, when do behaviors become habitual
66 days
habituates
Decreasing responsiveness with repeated stimulation
Associative learning
Learning that certain events occur together
What are the 2 types of associative learning
Classical conditioning and operant conditioning
Classical conditioning
Associating 2 events and thus anticipating the events
stimulus
Any event or situation that evokes a response
Respondent behavior
Behavior that occurs as an automatic response to some stimulus
Operant Conditioning
Learn to associate a response and its consequence
Operant behavior
Behavior that operates on the environment and produces a consequence
cognitive learning
acquisition of mental information by overserving, watching others, or through language
behaviorism
The view that psychology should be an objective science that studies behavior without reference to mental processes
Who was behind behaviorism
John B Watson
Neutral stimuli
Classical conditioning, a stimulus that elicits no response before conditioning
Unconditioned response
Classical conditioning, an unlearned naturally occurring response to an unconditioned stimulus
Unconditioned stimulus
Classical conditioning, a stimulus that unconditionally triggers an unconditioned response
Conditioned response
Classical conditioning, a learned response to a previously neutral stimulus
Conditioned stimulus
Classical conditioning, an originally neutral stimulus that after association with an unconditioned stimulus triggers a conditioned response
What are the 5 major conditioning processes
Acquisition
extinction
spontaneous recovery
generalization
discrimination
Acquisition - cc
Initial stage where a neutral stimulus and an unconditioned stimulus is linked
How much time should elapse between the NS and the UCS
1/2 a second
Classically conditioning is biologically adaptive because it helps prepare for good or bad events
:D
Higher order conditioning
Procedure where the conditioned stimulus in 1 conditioning experience is paired with a new neutral stimulus creating a second weaker conditioned stimulus
Extinction - cc
Diminishing of a conditioned response when an unconditioned stimulus does not follow a conditioned response
Spontaneous Recovery - cc
The reappearance of a weakened conditioned response
Generalization - cc
Tendency for similar stimuli to the conditioned stimulus to elicit similar responses
Discrimination -cc
Learned ability to distinguish between a conditioned stimulus and other stimulus
What did the Little Albert Experiment show
Learned fearsW
Who conducted the Little Albert Experiment
Watson and Rayner
What have people assumed about animals since Darwin
All animals share commonalities in their makeup and function, therefore the basic laws of learning were essentially similar in all animals
What did early behaviorists realize about animals learning ability
An animal’s capacity for conditioning is limited by biological constraints
preparedness
biological predisposition to learn associations that have survival value
What did John Garcia do
Proved the idea of preparedness and that not all animals have the same learning capabilities through this rat taste aversion experiment
instinctive drift
Drifitng back to biological behaviors
Law of effect
Thorndike’s principle that behaviors followed by favorable conseuqences become more likely, and behaviors followed by unfavorable consequences become less likely
What did BF Skinner develop
behavioral technology that revealed principles of bheavior control
operant chamber/Skinner Box
chamber containing a mechanism that an animal can manipulate to obtain a reinforcer
reinforcement
any events that strengthened the behavior it follows
shaping
procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
successive approximations
reinforce responses that are progressively getting closer to desired behavior
discriminative stimulus
stimulus that elicits a response after association with reinforcement
positive reinforcement
increasing behaviors by presenting a pleasurable stimulus
positive reinforcer
any stimulus that when presented after a response, strengthens the response
negative reinforcement
increasing behaviors by stopping or reducing an aversive stimulusn
negative reinforcer
any stimulus that when removed after a response strengthens the response
negative reinforcement is not
punishment
primary reinforcers
innately reinforcing stimulus
ex. stimulus that satisfies a biological need
conditioning reinforcers
stimulus that gains reinforcing power through its association with a primary reinforcer
reinforcement schedules
pattern that defines how often a desired response will be reinforced
continuous reinforcement schedule
reinforcing the desired response everytime it occurs
partial reinforcement schedules
reinforcing a response only part of the time
How does partial reinforcement schedules compare to continuous schedules
partial results in slower acquistion but greater resistance to extinction compared to continuous
what are the 4 schedules of partial reinforcement
fixed ratio
variable ratio
fixed interval
variable interval
fixed ratio schedules
reinforces a response only after a specified number of responses
variable ratio schedules
reinforces only after an unpredictable number of responses
fixed interval schedules
reinforces a response after a fixed time period
variable interval schedules
reinforces the first response after varying time intervals
What type of partial schedules have a higher response rate
ratio schedules compared to interval schedules
What type of partial schedules have a higher consistency
variable schedule compared to fixed schedules
punishment
event that tends to decrease the behavior it follows
positive punishment
administers an aversive stimulus
negative punishment
withdraw a rewarding stimulus
What do biological constraints effect how animals learn associations
they predispose organisms to learn associations that are naturally adaptive
instinctive drift
intendecy of learned behavior to gradually revert to biologically predisposed patterns
response - oc
voluntary, operates on the environment
acquisition - oc
associating a response with a consequence
extinction - oc
responding decreases when reinforcement stops
generalization - oc
responses learned in one situation occuring in other, similar situationsd
discrimination - oc
learning that some responses, but not others will be reinforced
what are the 3 influences on learning
Biological, psychological, and social-cultural
Cognitive map
Mental representation of the layout of one’s environment
latent learning
learning that occurs but is not apparent until there is an incentive to demonstrate it
insight learning
solving problems through sudden insight, contrasts with strategy-based solutions
observational learning
learning by observing others
Social learning theory
proposes that people learn social behavior by oberserbing and imitating other
modeling
the process of observing and imitating a specific behavior
mirror neurons
neurons that some scientists believe fire when we preform certain actions or observe another doing so. The brain’s mirror may enable imitation and empathy
prosocial behaviors
positive, helpful behavior
antisocial behavior
negative, harmful bheavior
Are the eggs a female has infinite or finite?
finite
Is the sperm a male has infinite or finite?
Infinite, they continue producing sperm
What are zygotes?
Fertilized eggs
When dot he cells begin to differentiate?
When the zygote has around 100 identical cells
What occurs 10 days after conception?
The germinal stage completes and the zygote attaches to the uterine wall
What does the zygote become?
The inner cells become the embryo and the outer cells become the placenta
What is the duty of the placenta?
It transfers nutrients and oxygen from mother to the embryo
tetragens
Agents that can reach the embryo or fetus during prenatal development and cause harm
Fetal alcohol syndrome
Physical and cognitive function deficits in children caused by heavy drinking during pregnancy
Are babies born with inborn reflexes or are they learned?
Babies are born with automatic reflex responses
What are 4 inborn baby reflexes?
Rooting, sucking, startling, and grasping
Habituation
Decreasing responsiveness with repeated stimulation, as infants gain familiarity with repeated exposure to a stimulus, their interest wanes and they look away sooner
