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
