Classical Conditioning Flashcards
Classical Conditioning
a learning process that occurs when 2 stimuli are repeatedly paired
Classical conditioning explanation for anxiety:
it is produced by exposure to an unconditioned stimulus that naturally elicits anxiety or, perhaps more often, by exposure to a conditioned stimulus that has been paired with an unconditioned stimulus that naturally elicits anxiety
Pseudoconditioning:
occurs when a neutral stimulus elicits a response due to the accidental pairing of the stimulus with another stimulus that evokes that response or when repeated exposure to a US increases the likelihood that the individual will respond to a neutral stimulus w/ a response similar to the UR.
Example: Repeated blasts of air to the eye (US) could render a person jumpy enough that they would blink (UR) whenever any sudden stimulus (CS) was presented
4 temporal relationships b/w CS and US to explain effectiveness of classical conditioning
delay conditioning
trace conditioning
simultaneous conditioning
backward conditioning
Delay conditioning
most efficient procedure for establishing conditioned response
type of forward conditioning; CS precedes and overlaps the US. Most effective interval is 0.5 seconds
Trace conditioning:
type of forward conditioning; presenting and terminating the CS prior to the US (less successful than delay conditioning)
Simultaneous conditioning:
presenting and withdrawing the CS and US at the same time (even less successful than trace conditioning)
Backward conditioning:
presenting the US prior to the CS.
- Does not usually produce conditioned response
Number of conditioning trials
- the more trials = stronger and more persistent the CR.
- Regardless of # of trials, the CR is usually weaker than the UR
Pre-exposure to the CS or US
Repeated exposure to the US and intended CS before CS and US are paired slows down acquisition of CR
Classical extinction:
- The gradual disappearance of conditioned response as the result of repeated presentation of CS alone
- Few trials needed to re-establish CR after extinction
Spontaneous recovery
Conditioned response is suppressed rather than eliminated by extinction trials
Stimulus Generalization
Individuals responds with CR not only to CS but also to stimuli similar to CS
Stimulus discrimination
Ability to discriminate between CS and similar stimuli and respond only to the CS with a CR
Experimental Neurosis
Result of individuals difficulty in discriminating between stimuli that are similar
Higher-order conditioning
An established CS is consistently presented following a neutral stimulus so that the new neutral stimulus also produces a CR.
**When using higher-order conditioning to establish a conditioned response: “a CS serves as a US”
Blocking
An association has been made between a CS and US, and the CS and a second neutral stimulus are then presented together prior to the US. The second neutral stimulus does not produce CR.
** “Present the CS prior to the US; then, once the CR is established, present the original CS simultaneously with a second CS prior to the US.”
Overshadowing
2 neutral stimuli are repeatedly presented together prior to the US. Presentation of the two stimuli together produce a CR, but when presented separately only one produces the CR.
Interventions based on Classical Conditioning
Counterconditioning
Aversive Counterconditioning
Classical Extinction
Interventions Based on Counterconditioning
Systematic Desensitization (Wolpe) Behavioral Sex Therapy (Masters and Johnson)
Systematic Desensitization
Wolpe
Eliminate anxiety responses
4 stages of Systematic Desensitization
- Relaxation Training
- Construction of an anxiety hierarchy
- Desensitization in Imagination
- In Vivo Desensitization
Dismantling Strategy
- Strategy comparing the effects of various components of a tx by administering different components to different groups, thus identifying the mechanism responsible for benefits
- Extinction, or repeated exposure to the CS without the US, is the primary factor responsible for effects of systematic desensitization (bell w/o dog food)
Behavioral Sex Therapy
Masters and Johnson
- Sensate focus: pairing situations that evoke performance anxiety with pleasurable physical sensations and relaxation.
- Most effective for treating premature ejaculation and Genito-Pelvic Pain/Penetration Disorder
Aversive Counterconditioning
the maladaptive bx or stimulus associated with it (CS) is paired with a US that naturally evokes pain or other unpleasant response
Interventions Based on Aversive Counterconditioning
In Vivo Aversion Therapy (Overt sensitization)
Covert Sensitization
In Vivo Aversion Therapy (Overt sensitization)
- Most effective: substance use disorders, paraphilias, self-injurious bxs
- The target bx is paired with aversive stimulus (i.e. cigarette smoking with noxious odor)
- Moderately effective for some patients/problems (mostly cigarette smoking)
- High relapse rates and limited generalizability
Covert Sensitization
- Individual imagines engaging in maladaptive bx and then imagines (rather than actually confront) an aversive stimulus
- To help establish alternative bxs, the client can envision a relief scene, in which the target bx is accompanied by pleasant sensations
Classical Extinction
the gradual disappearance of a conditioned response as the result of repeated presentation of the CS alone
Interventions Based on Classical Extinction
In Vivo with Response Prevention
Implosive Therapy
EMDR
Two-factor theory of learning:
Development of phobic disorder is the result of both classical and operant conditioning:
- A person dev’s anxiety reaction to a CS when it’s paired with a US that naturally elicits anxiety or other aversive response (classical conditioning).
- The person then avoids the CS because doing so enables avoidance of anxiety (negative reinforcement)
In Vivo with Response Prevention
Exposure to real life anxiety arousing stimuli for prolonged period and is prohibited from making usual avoidance bxs or anxiety-reducing response
- Use for: PTSD, OCD, anxiety, agoraphobia
- Flooding: exposure to the most anxiety provoking stimuli for prolonged period
- Graded (gradual) exposure
- Interoceptive Exposure: strategies used to evoke feared bodily cues that are associated with fear and anxiety reactions
Implosive Therapy
- Conducted in imagination and involves presenting feared stimulus vividly enough that it arouses high anxiety
- Involves having the client repeatedly imagine a feared stimulus (CS) in the absence of the stimulus (US) that initially evoked the fear in order to eliminate the conditioned fear response
- Belief that avoidance bxs are learned in childhood and represent conflicts related to sexual/aggressive impulses. Embellishes these with psychodynamic (snake and sexual symbolism of snake)
EMDR
- Based on assumption that exposure to trauma can block neurophysiological adaptive information-processing mechanism
- Rapid lateral eye movement with exposure and other techniques
- Eye movements are unnecessary and EMDR may be viewed as imaginal exposure technique.
