SAFMEDs Chapter 10: Social Learning and Biological Factors Flashcards
Phobias
- irrational fears
- persistent, excessive, unrealistic fear of an object, person, animal, activity or situation
Mary Cover Jones (1897-1987)
- used classical conditioning to reduce fearful responses
- Mother of behavior therapy
- Used desensitization therapy to reduce sensitivity to a feared stimulus
- Gave Peter sweet candy to reduce his fear of rabbits
- work was intially ignored until Joseph Wolpe built upon her original work
Behavior Therapy
- Mary Cover Jones
- identify and help change potentially self-destructive or unhealthy behaviors
- all behaviors are learned and can be changed
Desensitization
- reducing sensitivity to a feared stimulus
- introducing a series of stimuli that approximated a person’s phobia
Joseph Wolpe (1915-1997)
- built upon Mary Cover’s work in behavioral therapy
- expanded it to include reciprocal inhibition
- applied this principle to anxiety, hypothesizing that if a desired emotion is invoked at the presentation of an anxiety-producing stimulus over many repetitions, the undesirable anxiety response can be extinguished because the favorable and unfavorable responses cannot be evoked at the same time
Reciprocal inhibition
-a process of extinguishing an undesired response to stimuli by evoking a desired response in its place
Systematic desensitization
-a process that trains individuals with phobias in relaxation techniques and then exposes them to progressively more anxiety-provoking stimuli while they are relaxed
Anxiety hierarchy
- exposure hierarchy
- a list of feared objects and situations ranked from the least anxiety-provoking to the most anxiety-provoking
Biofeedback
- a biofeedback device monitors such functions as heart rate, blood pressure, and respiration
- Biofeedback is used to identify a patient’s relaxed state to compare to their anxious state.
Taste aversion
- Taste aversion or the Garcia effect occurs when you lose you taste for a food after having a bad experience with it.
- This phenomenon is unique because it rapidly pairs negative symptoms (nausea, illness, etc.) with eating a specific food, even though the food is not the cause of the symptoms.
John Garcia
- Garcia effect/taste aversion
- intial exposure to flavored water followed by a toxic reaction to radiation made rats averse to the water
Latent learning
- Learning that occurs but is not apparent until there is an incentive to demonstrate it.
Edward Tolman
- a psychologist who tried to teach rats to run through a maze over a series of one day trials
- He used different reinforcement schedules and noticed that the rats learned the maze but were not compelled to use the information without motivation
- This demonstrated latent learning
Cognitive map
-a mental representation that allows an organise to acquire, store and recall information both in a real, spatial world or in a metaphorical spatial environment
Robert Rescorla
-demonstrated that cognition is at work within classical conditioning
