Chapters 9-11 Flashcards
(41 cards)
Those that witness Failure
- Craig and Weinstein
- when someone witnessed someone else fail there was a stronger conditioned stress reaction than the those who seen another person succeed.
- failure alone and failure with shock, same reaction
Those that witness Success
- conditioned stress was not stronger from when people witnessed people fail.
Modeling and who is more impacted by modeling
- Bandura, Ross and Ross (children that seen the model get punished didn’t imitate the behavior)
- if model is the same gender
- attractive models
- imitate model if the act occurs soon after the model
Thomas and Tell, Aggression
- aggression influences a models behavior
- aggression that is real more likely to react to violent behavior
Vicarious Conditioning
- Bandura and Rosenthal observed V.C of fear occurred when the subject observed another after being shocked.
Mineka et al. (1984)
- did a study on monkeys
- reported that young monkeys learned snake phobias by observed older monkeys exhibit fear in the presences of snakes
Bandura and Rosenthal (1966)
- moderately aroused showed strong strong autonomic reaction to the tone paired with shock.
- highly aroused stopping attending ‘scary movie’ to stop watching if too scared
Systematic Desensitization
- (SD), relax training is followed by a gradual exposed to a feared stimulus starting with the least feared stimulus.
Flooding
- experienced feared stimulus all at once and associate CS with absence of UCS eliminating avoidance behaviors
- Baum; effectiveness of flooding increased with longer exposure to the feared stimulus
- Marks; agoraphobics fear eliminated in as few as 3 sessions
Types of Imitation
- aggression
- own gender imitation
- soon after stimuli has been exposed
- reinforced imitation
Neuroscience of Flooding
- release of cortisol
- exposure to feared stimulus is aversive and arouses sympathetic nervous system
- increased heart rate, resoiration and release of epinephrine
- effectiveness of flooding related to the cortisol response
Generalization vs Discrimination
- Generalization; the process in which we respond in the same way to similar stimuli
- Discrimination process in which an animal or person learns to respond in different ways to different stimuli
Bandura, Know Bobo doll studies
- this study children watched a person beat up a Bobo doll
- 1/3 seen the model get punished, 1/3 seen the model get rewarded, 1/3 seen no consequences
- the children that seen the model get punished did not imitate the behavior
Pavlov’s Insoluble discrimination problem
- 1 group of dogs were trained to discriminate between a circle and ellipse (SD-circle, Sdelta-ellipse)
- after this was learned ellipse was made more like the circle
- dogs unable to discriminate-salivate to both stimuli
- dogs should extreme agitation, the behaviors occurred outside the experimental situation
Brown (1942) study results
- trained rats to discriminate between two lights of differing brightness
- SD=bright light, Sdelta=dim light
- rats became agitated when dim light looked like bright light
**Aggression, Live vs. filmed
- agression
Generalization gradients, slope of line
- generalization gradients; psychologists constructed to study the level of generalization
- slope of the line indicates amount of generalization
- steeper the line the less generalization and the line that is less steep is more generalization
Excitatory vs. Inhibitory conditioning
- Excitatory conditioning is excite a responding- encourage responding any type of response
- Inhibitory conditioning is you do not want a response- something that you can not see, not encouraged, there is also no reward or punishment
Operant Procedures
- problem extinguishing phobic behaviors: fears motivates avoidance of phobic stimulus
Guttman and Kalish research
- investigated generalization of excitatory conditioning using hungry pigeons
- four groups were shown training stimuli 1/4 colors ranging from yellowish green to red
- during the generalization test; presented the color that corresponds to the pigeon groups training color presented 10 additional stimuli- 5 colors higher and lower on a color spectrum
- findings: responding declined as difference between training and test stimuli increased
- excitatory conditioning gradients can be generalization
Transposition
- process of transferring a learned relationship between two or more stimuli to a new set of stimuli
Errorless discrimination training
- Terrance View suggests Hull-Spence view not always true (had to make errors to learn)
- his method where animal never responds to negative stimulus
- subjects exposed initially to a stimuli where reward was available but early in training introduced to stimuli where reward is not available
- exposure to non-reward stimulus slowly increased
- association of the stimulus where reward is not available with non-reward results in conditioned inhibition and the establishment of aversive properties to non-reward stimulus
SD vs. S∆
- SD: reward available
- SDelta: aversive event
Eisenberger
- found that rewarding people for making a strong effort on one task increases the level ofeffort made on other tasks
