Learning Theory Flashcards
Classical Conditioning
Classical Conditioning terms
Pavlov
- Neutral (conditioned) stimulus paired with unconditioned stimulus
- in time, neutral stimulus alone elicits the response that is naturally elicited by the US
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
extinction
presentation of CS alone leads to disappearance of CR, needs “refresher trials”
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
temporal relationship
delay, trace, simultaneous
- delay- CS precedes and overlaps US
- trace- CS starts and ends before presenting US (weaker than delay)
- simultaneous CS and US at the same time, even weaker than trace
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
number of conditioning trials
the more trials, the stronger the CR
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
Pre-exposure to US or CS
slows down acquisition of CR
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
spontaneous recovery
even after extinction, CR would come back a day later, implying that learning is inhibited, but not lost
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
stimulus generalization
responding with a particular response to similar stimuli.
In classical conditioning, it refers to responding to stimuli similar to the CS with the CR
a 500Hz tone will cause a reaction with 400 and 600Hz tones
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
stimulus discrimination
training out the reaction to the 400Hz and 600Hz tones, specifying to the 500Hz tone only
Experimental Neurosis
agitation, aggression, that comes from increasingly difficult discriminations in Classical Conditioning (circle vs ellipse)
conflict between cortical excitation and inhibition
Classical Conditioning
Blocking
Blocking involves two conditioned stimuli, CS-a and CS-b. Either one is capable of being conditioned to produce the CR. However, if training begins with a phase in which only CS-a is paired with the US, and is then followed by a phase in which both CS-a and CS-b are paired with the US, then CS-b fails to produce the CR.
CS-a already predicted occurence of CR
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
overshadowing
two neutral stimuli repeatedly presented together prior to US, then theyre separated and only one produces the CR.
Tone+Light→Electric Shock
once you separate them, only one (the tone or the light) will produce the CR (fear)
whichever one produces the CR is more salient
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning
Watson
Little Albert
- US = loud sound
- UR = fear
- CS = white rat
- CR = white rat → fear
- generalized it to other animals
Classical Conditioning Interventions
Reciprocal inhibition
Wolpe
to alleviate anxiety reactions by pairing a stimulus (CS) that produces anxiety with a stimulus (US) that produces relaxation or other response that is incompatible with anxiety.
- US = meat powder
- UR = salivation
- CS = tone
- CR = tone → salivation
Classical Conditioning Interventions
Systematic desensitization
- application of counterconditioning (reciprocal inhibition) for eliminating anxiety responses
- pairing hierarchically arranged anxiety-evoking stimuli with relaxation.
relaxation training, hierarchy, imaginary desensitization, in vivo
Classical Conditioning Interventions
The dismantling strategy suggests
re: systematic desensitization
that extinction (rather than counterconditioning) is responsible for the effectiveness of systematic desensitization
Classical Conditioning Interventions
behavioral sex therapy
sensate focus, pairing situations that evoke performance anxiety with pleasurable sensations and relaxation
Classical Conditioning Interventions
in vivo aversion therapy
overt sensitization
- pair the behavior with an aversive stimulus (nausea, electric shock, noxious odor)
- used for substance use, paraphilias, and self-injurious behaviors
Classical Conditioning Interventions
covert sensitization
Covert sensitization is similar to in vivo aversion therapy except that the CS and US are presented in imagination.
Classical Conditioning Interventions
two-factor theory of learning
- phobic responses are the result of both classical and operant conditioning
- original phobia comes through avoiding a neutral stimulus when its paired with the US
- further avoidance of neutral stimulus is based on operant conditioning
Classical Conditioning Interventions
In-vivo ERP
exposed to anxiety arousing stimuli for a prolonged period and prohibited from performing usual avoidance
two types: flooding (all at once) and graded (gradual)
Classical Conditioning Interventions
self-directed exposure
in some situations, can be as effective as therapist guided exposure
Classical Conditioning Interventions
interoceptive exposure
evoke the feared body cues that are associated with fear and anxiety
spinning in a chair, breathing into a paper bag, cardio
Classical Conditioning Interventions
implosive therapy
- presenting feared stimulus vividly enough to arouse high levels of anxiety
- include psychodynamic meaning of the feared stimulus
Classical Conditioning Interventions
EMDR
- based on the assumption that exposure to a trauma can block a neuropsychological adaptive information processing mechanism
- found to not be more effective than imaginal exposure techniques
Operant Conditioning
Law of Effect
Thorndike’s law of effect proposes that, when behaviors are followed by “satisfying consequences,” they are more likely to increase or occur again.
Operant Conditioning
Reinforcement vs. Punishment
- Reinforcement is a consequence that increases the likelihood that a behavior will recur, while
- punishment is a consequence that decreases the likelihood that a behavior will recur
Operant Conditioning
Positive vs. Negative
- “positive” referring to the application of a stimulus (consequence) following a behavior and
- “negative” referring to the withdrawal or termination of a stimulus (consequence) following a behavior.
Operant Conditioning
primary vs. secondary reinforcer
- primary is things that you need, food water
- secondary is a means to get the things you need, money
Operant Conditioning
continuous vs intermittent schedules of reinforcement
- continuous- fastest acquisition of a behavior, satiation and extinction also high
- intermittent- switch to this after using continuous, best way to maintain a behavior
Operant Conditioning
Fixed Interval
fixed intervals that provide reinforcement at predetermined time intervals in which the subject makes at least 1 response
“scallop” effect, stop responding after enforcer delivered, again before
Operant Conditioning
Variable Interval
variable intervals that provide reinforcement at varying times with a predetermined average time interval
steady but low rate of response
Operant Conditioning
Fixed Ratio
fixed ratios that provide reinforcement after a predetermined number of responses; and variable ratios that provide reinforcement after a varying number of responses with the average number being predetermined
high, steady rate of responding
Operant Conditioning
Variable Ratio
variable ratio schedule yields high, stable response rates and the greatest resistance to extinction
highest rate of responding, responses resistant to extinction
Operant Conditioning
matching law
When using concurrent schedules of reinforcement, there are two or more simultaneous and independent schedules of reinforcement, each for a different response.
According to the matching law, in this situation, the organism will match its relative frequency of responding to the relative frequency of reinforcement for each response.
Operant Conditioning
superstitious behavior
accidental, non-contingent reinforcement leads to unrelated, odd behavior in order to elicit the stimulus response
Operant Conditioning
stimulus control
positive and negative discriminative stimuli
In operant conditioning, stimulus control is the process by which a behavior does or does not occur due to the presence of discriminative stimuli.
Positive discriminative stimuli signal that the behavior will be reinforced, while negative discriminative stimuli (S-delta stimuli) signal that the behavior will not be reinforced.
Operant Conditioning
stimulus/response generalization
- In operant and classical conditioning, stimulus generalization refers to responding with a particular response to similar stimuli
- responding to stimuli similar to the discriminative stimulus with the target behavior.
Operant Conditioning
Escape conditioning
an application of negative reinforcement in which the target behavior is an escape behavior - i.e., the organism engages in the behavior in order to escape the negative reinforcer
Operant Conditioning
Avoidance conditioning
- combines classical conditioning with negative reinforcement.
- a cue (positive discriminative stimulus) signals that the negative reinforcer is about to be applied so that the organism can avoid the negative reinforcer by performing the target behavior in the presence of the cue
Operant Interventions
Positive Reinforcement Factors
- contingency
- immediacy
- schedule of reinforcement
- magnitude
- verbal clarification
- prompts
Operant Interventions
contingency
positive reinforcement factor
reinforcer should only be available when the target behavior has been performed
Operant Interventions
immediacy
positive reinforcement factor
reinforcer must be delivered right away
Operant Interventions
schedule of reinforcement
positive reinforcement factor
acquisition on a continuous schedule, maintenance on an intermittent schedule
Operant Interventions
magnitude
positive reinforcement factor
greater positive reinforcement, greater effectiveness, after which satiation occurs
primary reinforcers are more susceptible to satiation than secondary
Operant Interventions
verbal clarification
positive reinforcement factor
relationship between behavior and reinforcer must be verbally reinforced
Operant Interventions
prompts
positive reinforcement factor
when a prompt signals that behavior will be reinforced, it is a positive discriminative stimulus
gradual removal of prompt is fading
Operant Interventions
gradual removal of prompt is
positive reinforcement factor
fading
Operant Interventions
thinning
positive reinforcement factor
reducing proportion of reinforcements
Operant Interventions
shaping
successive approximation training- involves teaching a new behavior through prompting and reinforcing behaviors that come closer and closer to the target behavior
Operant Interventions
chaining
involves establishing a sequence of responses (a “behavior chain”). With shaping, only the final behavior is of concern; but with chaining, the entire sequence of responses is important.
like baking a cake, each step must be done correctly
Operant Interventions
The Premack Principle
is an application of positive reinforcement that involves using a high-frequency behavior as a positive reinforcer for a low-frequency behavior.
grandma’s rule
Operant Interventions
differential reinforcement
combines positive reinforcement and extinction.
During a specified period of time, the individual is reinforced when he/she engages in behaviors other than the target behavior.
given token for playing with toys (target behavior- hand movements)
Operant Interventions
Punishment factors
- immediacy
- consistency
- intensity
- verbal clarification
- removal of all positive reinforcement
- reinforcement for alternative behaviors
Operant Interventions
immediacy
Punishment factors
- punishment should be applied at onset of behavior
Operant Interventions
consistency
Punishment factors
punishment applied at each performance of target behavior
Operant Interventions
intensity
Punishment factors
- punishment too strong, likely to produce avoidance, aggression
- too weak and gradually increasing, likely to produce habituation
Operant Interventions
verbal clarification
Punishment factors
contingent relationship between target behavior and punishment must be verbally expressed
Operant Interventions
removal of all positive reinforcement
Punishment factors
all stimuly that previously reinforced behavior must be identified and consistently withheld
Operant Interventions
reinforcement for alternative behaviors
Punishment factors
combining punishment with reinforcement of popsitive behavior
Operant Interventions
punishment does not eliminate a behavior, it just [ ] it
supresses it, meaning that effects of punishment are short term, limited to the setting where it was applied
Operant Interventions
reprimands
effectiveness
sometimes the reprimands become positive enforcers, increasing the target behavior, need to be paired with time-out
Operant Interventions
overcorrection
correct the consequences of his/her behavior (restitution) and/or practice corrective behaviors (positive practice). It may also require constant supervision and/or physical guidance.
