Title: Classical%20Conditioning%20Applications


1
Chapter 4
  • Classical Conditioning Applications

2
Emotional Conditioning
  • Wide range of emotional responses
  • Emotions universal
  • Positive and negative
  • Emotional response to stimulus reflexive
  • Conditioned Emotional Responses (CERs)

3
John Broadus Watson
  • Hard-line Behaviorism
  • British Empiricism (nurture over nature)
  • Early work with rats
  • Shifted to infant research

4
Conditioning of Fear
  • Watson Raynor (1920)
  • Albert B.
  • Mother a wet nurse at Harriet Lane Home (attached
    to Johns Hopkins University)
  • Albert first assessed at about 8 months
  • Emotionally stable, healthy

5
Method
  • Present white rat
  • No fear
  • Present white rat and bang metal bar
  • Produces CER of fear, avoidance, withdrawl
  • US noise, UR startle
  • CS rat CR fear
  • CER generalizes to other furry objects

6
  • Study went for several months
  • Intended to reverse CER conditioning, but Albert
    Bs mother ended her job at hospital
  • Mary Cover-Jones counter-conditioning with Peter

7
What Happened to Albert
  • Beck, Levinson Irons (2009)
  • Historical detective work
  • Albert B.s mother probably Arvilla Irons
    Merritte
  • Douglas Merritte, born 9 March 1919
  • Arvilla Merritte left Johns Hopkins
  • Worked as assistant for ill wife of farmer
  • Douglas Merritte died 10 May 1925, probably from
    meningitis

8
Name
  • Why Albert B.?
  • Ethical concerns with confidentiality not firmly
    established
  • Watson may have played name games
  • His sons William and James
  • His name from John Albert Broadus, Baptist
    minister Albert B.

9
What Happened to Watson
  • Affair with Rosalie Raynor, his grad student
  • Divorce, fired, resigned as president of APA
  • Worked for J. Walter Thompson advertising agency
    vice-president within two years
  • Ponds Cold Cream, Maxwell House coffee
  • Published books and articles on childcare
  • Psychological care of infant and child (1928)
  • Criticized by many modern child
    experts/advocates, but no more extreme than other
    childcare texts of the time
  • Strongly advocated against spanking and corporal
    punishment

10
Nonhuman Studies of Fear
  • Usually shock as US
  • Rats freeze
  • Train operant response train CS for aversive
    US, test suppression of operant response in
    presence and absence of CS
  • Suppression video

11
Suppression Ratio
  • 0 if behaviour entirely suppressed
  • 0.5 if no suppression

Pre-CS CS Calculation S.R.
25 25 25/(2525)25/50 0.5
25 0 0/(025)0/25 0
25 15 15/(1525)15/40 0.375
12
Prejudice
  • Prejudice related to hate
  • Hate conditionable
  • Staats Staats (1958)
  • Subjects rate nationalities
  • Paired positive, negative, neutral words with
    nationalities

13
Association
  • Political speeches
  • Media coverage
  • Negative images, words, impressions paired with
    identifiable group

14
Counter Conditioning
  • Mary Cover Jones (1924)
  • Eliminate phobia via classical conditioning
  • Peter feared rabbits
  • Peter eats snack (US) present rabbit (CS)
  • Associate positive US with CS

15
Systematic Desensitization
  • Relaxation techniques
  • Gradual introduction of phobic stimulus
  • Imagination up to real situation

16
Flooding
  • Flood patient with exposure to fear-inducing
    stimulus

17
Advertising
18
First-Order C.C. in Ads
  • Product (initially neutral --gt CS)
  • Pair with stimulus that elicits positive emotion
    (US)
  • Consumer sees product, has positive CR

19
Example
  • Postbank
  • US funny situation
  • UR happiness
  • CS brand
  • CR happiness, amusement, positive emotion

20
Second-Order C.C.
  • Use previously conditioned celebrity, situation,
    etc.
  • CS1 US
  • Now, pair brand (CS2) with CS1

21
Example
  • Chanel No. 5
  • Nicole Kiddman CS1
  • Positive feeling CR
  • Attractive, successful, lifestyle US
  • Positive feeling UR
  • Chanel No. 5 CS2
  • Assumption buy perfume, be rich, popular, get
    the cute guy, romance

22
Example
  • Japander.com
  • Brad Pitt and 503 Jeans
  • Pitt (CS1), leading man, celebrity, rich, pretty
    desirable (US), 503s (CS2)
  • Pierce Brosnan and VISA
  • Bond persona (CS1), excitement, adventure,
    sophistication desirable (US), VISA (CS2)

23
Paraphilia
24
Paraphilia
  • Incorrect love
  • Fetishism, masochism, pedophilia, rape, etc.
  • More common in males
  • Freud unconscious forces
  • Classical conditioning association formed

25
Example Masochism
  • Generally, CS is previously neutral
  • But, a US, by pairing with another strong US, can
    become a CS
  • Pavlov shock (CS) for food (US)
  • Masochism painful stimulus (CS) for stimulus
    eliciting sexual pleasure (US)

26
Counter Conditioning
  • Pair undesired CS with strongly aversive US
    (resulting in, e.g., nausea)
  • Aversion therapy
  • Treatment difficult with some forms of paraphilia
    (e.g., pedophilia)

27
Taste Aversion
28
Typically
  • Long-delay or trace conditioning
  • US is food poisoning, illness, etc.
  • UR is nausea induced pain
  • CS is novel food/flavour
  • CR is avoidance, nausea
  • Violation of contiguity?

29
Explanations?
  • Sensitization
  • Aftertaste
  • Biological preparedness
  • Taste aversion a special case

30
Biological Preparedness in Taste-Aversion
  • Garcia Koelling (1966)

Foot shock
X-ray
Water intake
Water intake
Pre-cond.
Post-cond.
Pre-cond.
Post-cond.
Flavoured water
Bright-noisy water
31
Explanation
  • Biological predispositions
  • Must know about CS-US relationship before
    predicting nature of CR
  • Certain stimuli more easily associated than others

32
Immune Function
33
Allergic Reaction
  • Release of histamines
  • Bodys immune response to allergens
  • Not all allergic responses biological
  • Can be learned

34
Examples
  • Pollen and artificial flowers
  • My allergy to cats

35
Russell et al. (1984)
  • Expose guinea pigs to BSA
  • Becomes allergen (US for histamine release)
  • Pair BSA with odour of fish or sulphur (CSs)
  • Expose guinea pigs to odours and get increased
    histamines (CR) in bloodstream
  • Preparatory value of classical conditioning

36
Schaller et al. (2010)
  • Subjects see photo sets of guns (G) or people
    with infectious diseases (ID)
  • Stress test given G more stressful than ID
  • Blood drawn, incubated with bacteria
  • ID subjects white blood cells produced 24
    increase in cytokine interleukin-6 (IL-6) over
    baseline
  • G subjects only show 7 increase in IL-6 over
    baseline
  • Photos CS, IL-6 production CR
