SO 3: Stimulus/Stimuli• Definition (note bold face in SOs!)
– An energy change that affects the organism through its receptors
• Examples of stimuli– Respondent: USs and CSs– Operant: SDs, S∆s, all consequences
• Some types of stimuli for humans (not for the exam)– Visual: electromagnetic wavelengths, photons (photo)– Auditory (hearing): vibration of molecules (phono)– Gustatory (taste): chemical changes molecules (chemo)– Olfactory (smell) - chemical changes (chemo) – Tactile (touch) - surface and deep nerve endings
(hear, taste, touch, see, feel: examples - physical energy change/receptors)
5
SO4A. When analyzing the behavior of a particular individual, environmental events are always classified from the perspective of the behaver.
(often mix up stimuli and responses: 2 important points about stimuli)
6
Stimulus vs. BehaviorIn the following examples of operant relations, should we classify the consequence for the R as a behavior or a stimulus?
A. R (answers lecture question correctly)--> Praise
B. R (answers lecture question correctly)-->OK gesture
C. R (drink hot liquid)-->Pain (burn tongue)
D. R (rat presses lever)-->Light comes on
E. R (baby coos)-->Parent strokes baby’s arm
7
SO4B
An energy change cannot be a stimulus for an organism if:
1. The organism does not have a receptor that can detect it
1. The organism’s receptor is damaged and thus cannot detect it
In this case, the energy change can be a stimulus for one person or organism of the same species, but not for the organism with the damaged receptor
(important to stress energy change that affects the receptors, cont)
8
SO4BA. Dog whistles: Phonoreceptors of dogs can detect faster vibrations of molecules than can the phonoreceptors of humans.
High tones, while energy changes, can be stimuli for dogs but not for humans because humans do not have receptors that can detect them.
B. X-rays:X-rays are energy changes, but they cannot be stimuli for humans because humans do not have receptors that can detect them.
C. Hunter’s phonoreceptors damaged due to firing rifles close to his/her ear so high tones do not affect his/her
receptors (problem for veterans as well)high tones can be stimuli for others, but not for this hunter.
(Note, all are energy changes! Refer to def of stimulus)
SO4B – Another Example• The Mosquito: Box that emits a shrill piercing noise • Used to prevent loitering by teens• The sound is audible to teens and young adults, but
typically not adults (older than early 20s)• Can be heard by animals and babies, but is only
aversive to children older than 12 – “teen-repellent”• Teens say: “It’s horrible, loud, and irritating. It’s this
screeching sound that you have to get away from or it will drive you crazy.”
• Why? Heard by teens and young adults who still have sensitive hair cells in their inner ears, hair cells that don’t develop until teen years
9
10
SO 5: Behavior/Response(Dead man’s - person’s - rule)
1. Movement of the skeletal muscles (striped, striated)Muscles attached to bones and move bones when they contract: fingers, arms, legs, back, vocal app.
2. Movement of the smooth muscles Located in blood vessels - face flushes or blanchesAround hair follicles - hair stands up on endIn eye - pupils constrict or dilateDigestive, reproductive, respiratory system, cardiac muscle
3. Secretion of the glandsSweat glands, salivary glands, lachrimal glands, adrenal gland
(also electrical conductivity/activity of skin, gsr, but not requiring this)
11
SO 6: Types of Behaviors and Relationship to Type of Conditioning
•Relationship to operant and respondent relations and conditioning (typically)
–Movement of skeletal muscles: Operant– (a) Movement of the smooth muscles & (b) Secretion of the glands*: Respondent Commonality? Behaviors controlled by autonomic
nervous system
(*also GSR, but not requiring this: clearly exceptions - next slide)
12
SO 7 Exception
US (pain to hand/foot) ---> UR (hand/foot withdrawal)
Why is this an exception?
The relation is a respondent relation, but theresponse is movement of the skeletal muscles rather than movement of the smooth muscles or glandular secretion.
13
SO 8 Behavior vs. Behavioral Relations:What is the Difference?
• Behavior– Movement of the skeletal muscles, movement of the
smooth muscles, and glandular secretion• Behavioral Relations
– Behavior plus causal stimuli, e.g., Respondent: US UR
CS CR Operant: R SR or Sr
SD: R SR or SrMO:SD:RSR or Sr
(examples next)
14
SO 8 Behavior vs. Behavioral Relations:Examples
• Respondent:– Behavior: salivation– Relation: US (food in mouth) UR (salivation)– Relation: CS (tone) CR (salivation)
• Operant:– Behavior: Press power button on TV remote– Relation: R (press button) Sr (TV comes on)– Behavior: rat presses a lever– Relation:
MO (food dep): SD (light on): R (press lever) SR (food)
(not NS does not elicit a response)
15
SO 8 Behavior vs. Behavioral Relations:Why is the distinction important?*
• A behavior, such as crying, can be caused by very different variables - it can also have multiple causes. (onions, operant crying, both - pain, Sr)– US (fumes from peeling onions) UR (crying)– R (woman crying) Sr (please don’t cry, I didn’t mean it)– US (pain) UR (crying)
R (crying) Sr (poor baby, hug)• Respondent relations: tendency to call a behavior rather
than a relation inherited– US (food in mouth) UR (salivation)– CS (tone) CR (salivation)
• In order to understand and change behavior we must know what is causing it
(*this slide, NFE)
16
SO9: Three Common Misconceptions, Operant vs. Respondent Relations
• Respondent behavior is inherited while operant behavior is learned
• Respondent behavior is physiological while operant behavior is not
• Respondent behavior is involuntary while operant behavior is voluntary*
(what’s wrong with these statements and why? No answer on slide, * Malottians beware!)
17
SO10 Unconditioned Respondent RelationsExamples in study objectives; for the examlearn the ones numbered 1, 2, 3, 5, 6, 7, & 11
1. US (light increase) --> UR (pupil of eye constricts)2. US (light decrease) --> UR (pupil of eye dilates)3. US (touch to eye/chemical irritant) --> UR (lachrimal gland secretion)4. US (irritation to nasal mucosa) --> UR (sneezing)5. US (irritation to throat) --> UR (cough)6. US (low temperature) --> UR (shivering, surface vasoconstriction)7. US (high temperature) --> UR (sweating, surface vasodilation)8. US (cold/fright) --> UR (hair stands on end)9. US (food in mouth) --> UR (salivation)10. US (bad food in stomach) --> UR (vomiting)11. (NEXT SLIDE - EMOTIONS)
(focus on respondent this unit. On exam, if US, give UR; if UR, give US,or whole relation)
18
SOs 10 &11: EmotionsALL emotions (joy, anger, sadness) consist of:
A collection of respondent behaviors elicited by a stimulus that is (1) painful, (2) very intense,or (3) very unusual and together is called the
activation syndrome.US UR: Activation Syndrome
Pain Heart rate increaseVery intense stimulus Adrenaline secretionVery unusual/surprising Release of sugar into blood stream
Blood vessel constrictionGalvanic skin response
(pain is always a stimulus, never a response!; note respondent – do not leave this outof the definition - it is a critical part - emotions are not operant behavior)
19
SO 12: Lower-order and Higher-order Respondent Conditioning
Definition: Respondent Conditioning (not for the exam):
A neutral stimulus (one that does not elicit the response to be conditioned) is repeatedly paired with a stimulus that does elicit the response (either a US or a CS), and the NS becomes a CS that elicits the same response (or a response that is the “same” but varies in intensity or magnitude).
(Conditioning, making new CS->CR relations)
20
SO12: Lower-order Respondent Conditioning Diagram
Four parts to the diagram!
NS does NOT elicit R (either as a UR or CR)US ----------> URNS/US -----> UR (NS and US paired several times)CS ----------> CR
Critical Features:• US always elicits a UR (never an “R” or “CR”)• NS always precedes US to insure conditioning• Pairing is symbolized with / (Not an arrow)• NS becomes a CS when it elicits the response• CS always elicits a CR (never an “R” or “UR”)• CS must occasionally be paired with US
(exam: not ask critical features)
21
SO 12A: Pavlov’s Original StudyExample of Lower-order Conditioning
NS (tone) does not elicit R (salivation)
US (meat powder in mouth) -----> UR (salivation)
NS (tone) / US (meat powder in mouth) -----> UR (salivation)
CS (tone) ----> CR (salivation)
Review of Critical Features:• US always elicits a UR (never an “R” or “CR”)• NS always precedes US to insure conditioning• Pairing is symbolized with /• NS becomes a CS when it elicits the response• CS always elicits a CR (never an “R” or “UR”)• CS must occasionally be paired with US(Russian
Physiologist)
22
Skip to SO 14: Respondent ExtinctionNS (tone) does not elicit R (salivation)US (meat powder in mouth) ---> UR (salivation)NS/US (meat powder in mouth ---> UR (salivation)CS (tone) ---> CR (salivation)
How would you respondently extinguish the CR(the salivation response) to the CS (the tone)?
Repeatedly present the CS (the tone) without the US (meat powder in the mouth)
Why not present the CS? (without repeatedly)
(Problem with “pair” instead of “present”; Extinguish vs. extinct, next slide)
23
Extinguish vs. extinct
24
SO 12C: Higher-order Respondent Conditioning
Lower-OrderNS does not elicit RUS ---> URNS/US ---> URCS ---> CR
Higher-OrderNS does not elicit RCS1 ---> CR1
NS/CS1 ---> CR1
CS2 ---> CR2
SO 12D: Difference in WordsIn lower-order conditioning, the NS is repeatedlypaired with a US while in higher-order conditioningthe NS is repeatedly paired with a CS.
25
SO 12C: Example of Higher-Order Respondent Conditioning
Pavlov’s Lower-Order Conditioning Study
NS (tone) does not elicit R (salivation)US (meat powder in mouth) ---> UR (salivation)NS/US (meat powder in mouth ---> UR (salivation)CS (tone) ---> CR (salivation)
Higher-order Respondent Conditioning
NS (bright orange light) does not elicit R (salivation)CS1 (tone) ---> CR1 (salivation)NS (bright orange light)/CS1 (tone) ---> CR1 (salivation)CS2 (orange light) ---> CR2 (salivation)
(cool examples in text related to advertising; George Clooney, Jack Sparrow/Johnny Depp, lovable Geico gecco; on exam, CS1 - second diagram)
26
SO 12E: Watson & Raynor, Little AlbertRespondent Conditioning of Emotions
NS (white rat) does not elicit R (fear, startle)
US (loud noise) ---> UR (fear, startle)
/NS (white rat) US (loud noise) ---> UR (fear, startle)
CS (white rat) ---> CR (fear, startle)
REVIEW SO 14: Extinction of CR
(emotions vs. simple reflexes, all emotions were genetic, 11th, diagram this study, question, not answer,process of extinction often forms the basis for treatment of most phobias; article 2 yrs ago – who Was little Albert and what happened to him? American Psychologist)
How would you extinguish the fear,startle response?
27
SO 15Assume, as actually happened, that Watson and Raynor did not extinguish the fear, startle response.
Also, assume Little Albert has not had any contact with white rats for 1 year after he left Watson and Raynor.
If you showed him a rat, would he exhibit a fear, startle response?
28
SO 16: Counterconditioning
Counterconditioning is NOT the same thing as extinction.
Extinction: The CR is eliminated by repeatedly presenting the CS without pairing it again with the US or CS1
Counterconditioning: Not only is the CR eliminated, but it is replaced with anincompatible response.
The CS that elicits the CR is repeatedly paired with a stimulus that elicits an incompatible response.
(Extinction is not the same as elimination, specific process, counterconditioning usually faster; also used to treat phobias)
29
SO 16: Peter’s Original Conditioning: Same as Little Albert’s
NS (rabbit) does not elicit R (fear, startle)
US (loud noise) ---> UR (fear, startle)
/NS (rabbit) US (loud noise) ---> UR (fear, startle)
CS (rabbit) ---> CR (fear, startle)
(NFE, but important so that you understand the counterconditioning)
(SO16A, diagram; SO16B, conditioned rabbit to elicit unpleasant emotions;stress NS first line, extinction embedded)
31
SOs 17-18: Staats & Staats• To date: Respondent conditioning can
account for emotions to stimuli that are paired with a US, e.g., Little Albert’s fear/startle response
• Series of three studies showing how emotions to things/people/ethnic groups that we have never had contact with can be respondently conditioned
Nonsense syllablesNames of males (e.g., Tom, Bill)Nationalities (e.g., German, Dutch, Swedish)
(higher order conditioning, increasing applied relevance and implications)
32
Staats & Staats Study• Participants were college students• Slides with names of nationalities shown on a
screen• Words said to participants, which they
repeated while slides were shown• Purpose? How visual learning affected
auditory learning• Ps told they would be asked to recall as many
of the words as possible.
33
1. Slides saying German, Italian, French were paired with words that did not elicit emotional reactionsNS (German)/NS (words) No emotional reaction
2. Slides saying Dutch were paired with words that elicited pleasant emotional reactionsNS (Dutch)/CS1 (joy, happiness) CR1 (plsnt emotions)
3. Slides saying Swedish were paired with words that elicited negative emotional reactionsNS (Swedish)/CS1 (death, pain) CR1 (unplsnt emotions
Staats and Staats Study, cont.
NS = nationalities (German, Dutch, Swedish)NS = words that did not elicit emotional reactions (book, table)CS1 = words that elicited emotional reactions (joy, happiness)
(SO17: full diagrams later)
34
Staats & Staats Dependent Variable
College students rated the extent to which the nationalities were pleasant or unpleasant on a 7-point rating scale.
They rated:• German, Italian, and French as neutral.• Dutch as very positive/pleasant• Swedish as very negative/unpleasant
When asked why they rated them that way, the students could not tell the experimenters. That is, the conditioning occurred completely without their awareness.
35
NS (German) does not elicit R (any emotions)NS (table, chair) ---> No R (no emotions)NS (German)/NS (table, chair) ---> No R (no emotions)NS (German) ---> No R (no emotions)
NS (Dutch) does not elicit R (pleasant emotions)CS1 (joy, gift) ---> CR1 (pleasant emotions)NS (Dutch)/CS1 (joy, gift) ---> CR1 (pleasant emotions)CS2 (Dutch) ---> CR2 (pleasant emotions)
NS (Swedish) does not elicit R (neg. emotions)CS1 (death, pain) ---> CR1 (neg. emotions)NS (Swedish)/CS1 (death, pain) ---> CR1 (neg. emotions)CS2 (Swedish) ---> CR2 (neg. emotions)
(note: first is not really respondent conding; must begin with nationalities that are NS, not Dutch here)
SO 17: Diagrams for Staats and Staats
36
SO 18: Staats & Staats Wrap-up • The DV consisted of the extent to which students
rated the nationalities as pleasant/unpleasant on a 7-point rating scale.Was this the CR? Why or why not?
• Chance called the words “neutral words,” “positive words,” and “negative words.” This is NOT good behavioral terminology.What is wrong with this way of describing the words?
(not in study objectives, but fair game for the exam)
(Stimulus vs. response)
37
Staats & Staats Implications
If you grow up in a social environment where international or minority groups are always described in negative terms, you are going to develop negative emotional reactions to those groups, even if you have not had any contact with them.
If Italians are always paired with “gangsters,” “mafia,” “Jersey Shore,” if females are described as “inferior,” if Jews are described as “sly” and “shrewd,” if Arabs and Muslims are always described as “terrorists,” if homosexuals are always described as “immoral,” etc., you can develop negative reactions to those groups.
38
SO 19: Pavlov’s StudyCounterconditioning: Dogs and Masochists
NS (shock) does not elicit R (salivation)
US (meat powder in mouth) -----> UR (salivation)
NS (shock) / US (meat powder in mouth) -----> UR (salivation)
CS (shock) ----> CR (salivation)
(dogs acted as if they “liked” the shock, shock did not elicit normal Rs after conditioning, Chance - not refer to this as counterconditioning,not always going to happen - factors??)
39
SO 20: Respondent Conditioning of Allergic Reactions*
NS (shape, color, smell of rose) does not elicit R (allergic reaction)
CS (shape, color, smell of rose) CR (allergic reaction)
(How could an artificial rose come to cause an allergic reaction? Is the person reallysuffering or just being “psychosomatic?” and a hypochondriac?); No different than how the sight and smell of food come to elicit salivation
* NFE, unless I add it in lecture
US (allergen) UR (allergic reaction)NS (shape, color, smell of rose)/US (allergen) UR (allergies)
CS (artificial rose, scented rose candle) CR (allergic reaction)Thus:
SO 21: Respondent Conditioning and Drug Overdoses*
• Shepard Siegal’s work on respondent conditioning can help explain why:– People develop drug tolerances over time
and have to take more drugs to get the same “high”
– Drug addicts who get “clean” at a rehab facility often have such a high relapse rate
– Some people die from overdoses when they take the same amount of drugs in a different place/setting
40*NFE unless I add it in lecture
SO 21, cont.
41
US (addictive drugs) 1. Physiological effects due to the drug + 2. Physiological compensatory
responses to “offset” the effects of the drugs
When an NS is paired with the US (dope) the responses that become conditioned are the2nd set of responses, not the first.
SO 21, cont.
42
NS (drug paraphernalia) do not elicit R (compensatory Rs) (stimuli in apt., friends)
US (drug) UR (compensatory Rs after initial drug effects)
1. Now, US (dope) UR (drug effects)• But, the compensatory Rs have already been elicited
by the CSs in the environment, thus the effects of the drug are not as great
•So, a person needs more and more of the drug to get the same “high”
And, remember, respondent conditioning doesn’t happen all at once, so the tolerance develops gradually as the CSs come to elicit the CRs
(gathered at the typical place with the “usual suspects” to do some dope)
SO 21, cont: Drug Overdoses
44
Now, what is going to happen if a person shoots up in a completely new place/setting?
1.CSs (drug stuff) CRs (compensatory Rs)But, there are not as many CSs so the compensatory Rs will be a lot weaker, not as strong counteraction
2.Take dope, same amount:
SO 21, cont: Drug Relapse• Why did returning Vietnam vets who got
“clean” at rehab have such a low recidivism rate in comparison to the average recidivism rate?
• Why is there such a high recidivism rate when individuals get clean then return home?
• Siegel’s story of a drug addict who got clean and then experienced full-fledged withdrawal symptoms when he crossed the GW Bridge, returning to NYC
45
SO 21, cont: Drug Relapse
• The compensatory responses are also what is commonly referred to as “withdrawal symptoms”
• They create “cravings” for the drugs if elicited in the drug’s absence
• So, if CSs elicit the compensatory responses then individuals will have a strong tendency to do drugs to relieve those compensatory responses (withdrawal symptoms)
46
SO 21, cont: Drug Relapse• Former drug addict returning to NYC
CSs (GW Bridge, NYC skyline, etc.) CRs (comp Rs)
• People who get clean and return homeCSs (streets, home, friends, etc.) CRs (comp Rs)
In contrast to:• Clean Vietnam vets who returned to their home
No or few CSs (all related to Vietnam and fellow soldiers)Therefore, no or only mild withdrawal symptoms
47
What important point about CSsCRs and respondent extinction do the first two illustrate?
(last slide on this – next slide, term “elicit”)
48
SO 13: Elicit• Simple Rule:
USs elicit URs, CSs elicit CRs_________________________________• Elicit is only used in respondent
relations• ONLY USs and CSs elicit responses:
Organisms do NOT• Only responses can be elicited
49
SO13 Examples: Is elicit used correctly?
• When the temperature is cold, a person elicits a shivering response.
• The SD (a tone) elicited the behavior of turning in a circle by the pigeon.
• The CS (a tone) elicited the CR (salivation).
• In lower order conditioning, the NS elicits the US.
