In Pavlov’s experiments, stimuli that naturally elicited salivation (meat powder) were deemed ___ ___ and the salivation as the ___ ___. The bell that played with the presentation of the meat powder eventually became the ___ ___ after enough conditioning trials, and salivation produced by the bell also became the ___ ___.
meat powder were deemed unconditioned stimuli; salivation unconditioned response;
bell conditioned stimulus; salivation conditioned response
In classical conditioning, the US (unconditioned stim) seems to depend on the presentation of the CS (conditioned stim), which is why [trace/delay/simultaneous/backward] conditioning is the most effective form of it with respect to timing
delay (CS precedes US and they overlap with delay of about 1/2 second)
(trace is similar to delay but CS stops before US is presented, 2nd most effective)
(simultaneous is presenting and withdrawing stim at the same time, 3rd most effective)
(backwards conditioning is presenting US before CS and is not effective conditioning (all other types are “forward” conditioning))
T/F: typically after about 100 classical conditioning trials, usually the conditioned response (CR) becomes stronger than the unconditioned resp (UR)
F: regardless of # of trials, the CR is usually weaker in intensity and or magnitude than the UR, although higher # of trials is related to higher strength and persistence of CR
T/F: repeated exposure of the US (unconditioned stim) or the intended CS (conditioned stim) in classical conditioning without their pairing tends to in fact increase the acquisition of the CR (conditioned resp)
F: repeated exposure of either of these tends to slow down classical conditioning and acquiring the conditioned response
In classical extinction, a conditioned response (CR) ___ly disappears as a result of the CS alone, although occasional “refresher trials” with conditioned pairings can help avoid extinction. Spontaneous ___ occurs when an extinguished conditioned response recurs to the CS without additional pairings, showing that conditioning is suppressed or inhibited but never lost.
gradually disappears; Spontaneous recovery (which can also occur with operant conditioning)
stimulus g___: responding with conditioned response to stimuli that resemble the conditioned stimuli
stimulus generalization (e.g., if the CS was a bell sound, salivating to a sound at a diff frequency or seeing a picture of a bell)
The opposite of stimulus generalization is stimulus discrimination, in which selective ___ and ___ occur, in which the intended CS is paired with the US and similar stimuli are not and subjects are taught to respond with a CR only to intended stimuli.
selective reinforcement and extinction
In stimulus discrimination trials, experimental neurosis can arise when discriminations are ___
difficult (involves unusual behaviors like restlessness, aggressiveness, or fear)
Higher-order conditioning occurs when a new neutral stimulus is paired with ___ so that the new stimulus produces a conditioned response
conditioned stimulus (CS)
(higher-order conditioning –> less intense CR than initial CR/CS results)
(previously established CS serves as an US to establish a CR for a new neutral stimulus) (e.g., the bell and meat powder go together and salivation occurs, bell causes salivation, bell and red light go together, red light causes salivation too)
Once a CS/CR pattern is established in classical conditioning, if a new neutral stimulus repeatedly precedes the CS it can evenutally elicit the CR [this is called ___] but if the CS and the new stimuli are presented simultaneously this does not produce conditioning [this is called ___].
this is called higher-order conditioning;
this is called blocking (the new stim is redundant information)
(overshadowing occurs when two neutral stimuli occur at the same time prior to UR. learning occurs for both stimuli presented at once or just one of the stimuli but not the other, so one is overshadowed by the other because it is less salient.)
John B. ___ is considered the “father of American behaviorism.” He is famous for his “Little Albert” studies, where he conditioned a small child to fear white rats and other similar stimuli.
Watson (he argued that all learning is the result of classical conditioning and rejected the use of introspection as the primary method of psychology)
(interventions based on counterconditioning) reciprocal inhibition was developed by Wolpe to alleviate anxiety rxns by pairing a ___ stimulus that produces anxiety (CR) with a stimulus (US) that produces r___ or other response that is incompatible with anxiety.
pairing a conditioned stimulus…that produces relaxation (examples include systematic desensitization and behavioral sex therapy)
read: systematic desensitization entails 4 stages
relaxation training, making an anxiety hierarchy, desensitization in imagination, and in vivo desensitization (using SUDS esp. in anxiety hierarchy stage)
at what stage of systematic desensitization would techniques like progressive muscle relaxation and deep breathing be introduced? [anxiety hierarchy, desensitization in imagination, desensitization in vivo, relaxation training]
relaxation training
The dismantling strategy in therapeutic outcomes research has shown that, in systematic desensitization, ext___, or repeated ex___ to the CS w/out the US, is the primary factor responsible for beneficial effects of this counterconditioning technique.
extinction, or repeated exposure to the CS w/out the US
Sensate focus by Masters and Johnson (1970) involves pairing situations that evoke sexual performance anxiety with p___ physical sensations and re___.
pleasurable physical sensations and relaxation (sex therapy found to be most effective for treating premature ejaculation and vaginismus (Genito-Pelvic Pain Disorder) with “squeeze technique” and relaxation/progressive dilators respectively)
In vivo aversion therapy has shown to be moderately effective initially for some patients and some problems, especially cigarette smoking, although relapse rates tend to be high and generalizability is limited. T/F?
T (it’s most successful when aversive stimulus or its consequence is similar to target behavior, like nausea-inducing drugs for ETOH or rapid smoking for cigarettes)
In contrast to in vivo aversion therapy, covert sensitization involves having clients imagine themselves engaging in the maladaptive behavior and experiencing an aversive stimulus. Give an example of one such technique.
a smoker envisions themselves smoking and getting sick and throwing up on themselves, or gambling and going to play the slots and being painfully electrically shocked (also involves imagining a “relief” scene in which not doing the behavior is accompanied by pleasant sensations) (the target bh is the conditioned stimulus, while the aversive stimulus is the unconditioned stimulus)
Read: interventions based on counterconditioning involve pairing (-) CS with pleasant or antithetical stimuli; interventions based on aversive counterconditioning involve pairing an undesired behavior with unpleasant or demotivating stimuli;
interventions based on classical extinction involve presenting the avoided CS without the US while preventing avoidance of CS so that CR extinguishes. It is based on Mowrer’s two factor learning, which says that phobias are the result of classical and operant conditioning - intentionally avoiding a learned fear response
T/F: In vivo exposure with response prevention is a treatment for schizophrenia.
F: more like OCD or other anxiety and related disorders (involves exposure to avoided stimuli or obsessional cues while preventing compensatory rituals)
Evaluation of in vivo exposure with response prevention (ERP) show that
1) prolonged, continuous exposure to CS is usually [less/more] effective than several brief exposures
2) simultaneous use of a [sleep agent/tranquilizer] that reduces anxiety can enhance effects
3) for it to work, ERP must be done with only a therapist, T/F?
1) prolonged more effective than several brief
2) tranquilizer can help
3) F: sometimes can be done in group setting, or alone, or with a partner (for agoraphobia and OCD)
T/F: implosive therapy involves presenting the feared stimulus vividly in the imagination of a patient to the point of high anxiety in order to extinguish the avoidance response.
T (it makes use of psychodynamic themes to embellish the internal images)
EMDR has only been shown to be effective for PTSD. T/F?
F (also used for panic attacks, phobias, depression, and SU disorders)
Read: While EMDR assumes that rapid eye movements or bilateral stimulation can trigger the neurophysiological adaptive information-processing mechanism that trauma can disrupt, some researchers argue that the eye movements are an unnecessary component of the treatment and that EMDR is largely an imaginal exposure technique (Davidson and Parker, 2001).
Meanwhile, other researchers have criticized these researchers for the inappropriate populations and limited amount of treatment in their meta-analysis. EMDR has a conditional recommendation for PTSD from the APA, a place in the highest category of effectiveness and research support from the American Psychiatric Association and the VA, as well as a strong recommendation from the International Society for Traumatic Stress Studies.
