SO 2: Basic Behavioral Principles
1. Reinforcement
A. Positive
B. Negative (difference between pos & neg?)
1. Escape (alarm clock, safety harness after chime)
2. Avoidance (safety harness before chime; child
plays quietly)
2. Punishment
3. Operant Extinction (withheld, not withdrawn)
Examples and sample exam questions
on page 19 of the Study Objectives
(terminates or avoids, e-aversive stim that comes before, TV screen clears, food reinforcement, avoid vs. pun, Decrease to avoid conseq – not correct;
student asks question, professor says; pun dec; avoid incr; cannot increase a nonbehavior; extinction burst, taking truck away, sending a child 3
from the
table; language will be very clear in the examples I provide on the exam)
SO 2: Some Examples (in SOs)
• Rafael gets a muscle cramp. He massages the
muscle and the cramp immediately decreases in
severity. As a result, when Rafael gets a muscle
cramp in the future, he massages it more often than
he had done in the past.
• A student wants to make a copy. She inserts her
Bronco Card into a copy machine and pushes the
button. No copies are made. The student pushes
and pushes the button, but still no copies are made.
As a result, the student pushes the copy button on
that machine less often.
4
SO 2 (Examples, cont.)
• Barbara calls her little sister a scardy cat and the
little sister immediately begins to cry. As a result,
Barbara calls her sister a scardy cat more often in
the future.
• A worker is standing around with co-workers and
puts on her hard hat before entering the
construction area. Her supervisor sees this and
immediately says “Hey, that’s great, Grace!
Thanks for making safety first a reality!” As a
result, Grace puts on her hard hat less often in the
future.
(effect on behavior, can’t just look at the conseq; teachers and elementary school children
, criticism,attention)
5
SO 2: Final Examples
• Jake gets bitten by bugs when he walks in the woods.
One day, he puts on a new kind of bug repellant and
does not get bitten by bugs. As a result, in the future, he
puts on that new kind of bug repellant before he walks in
the woods more often.
• Suzie is a 5-year old who loves the beach – playing in the
sand, running around, splashing in the water. She throws
sand in the face of her two cousins and her parents
immediately require her to sit on the beach blanket for 5
minutes. As a result, Suzie doesn’t throw sand at her
cousins as often in the future.
(exam examples, Tas can use examples from your exams)

SR NOT UR
UR=Unconditioned Response
Conditioned Reinforcer

SO 4-5: Introduction
Chance’s material starts with animal training, focus of
this unit
– Dolphin training, e.g., Shedd Aquarium, San Diego Sea
World, Georgia Aquarium
– Behavioral enrichment in zoos, e.g., Honolulu Zoo,
Atlanta Zoo, Brookfield Zoo, Disney Land and Disney
World, Busch Gardens-Orlando
– Animal training (dogs, cats, horses, etc.), Karen Pryor
(Don’t shoot the dog), Mary Burch & Jon Bailey (How
dogs learn), Mary Burch, (Citizen Canine – AKA), Gillette
Obedience Training (Galesburg, MI), Applied animal
training practicum (WMU, UMN-Duluth)
– “Clicker/Tag Training”: Clicker as an Sr (athletes)
(: animal training; Gulf oil spill dogs and turtle eggs; Binti Jua – Brookfield zoo, Otto Fad, Ken Ramirez)
8
SO 5: The Aggressive Bull Elephant
San Diego Zoo: Intro
• An aggressive elephant
• Husbandry includes cutting off calluses on feet,
otherwise, eventually they can’t walk
• G. Priest established a “click” as an Sr
• Shaped the elephant to walk to a wall with hole in
it, put its foot through the hole, and stand
patiently while the vet cut off the calluses.
(SO4 on your own)
9
SO 5: Development and Testing of an Sr
Development
When food deprived (MO):
NS (click) / SR (carrot) (no behavior is necessary!)
NS becomes an Sr
Critical features:
• The NS is paired with an SR (or Sr) (NOT a US!)
• The NS precedes the SR when pairing takes place
• No behavior is necessary
• The NS becomes an Sr
(NOT a CS!)
(How trainers made click; all in SOs,click, crticial features on slide - not for the exam
need to test)
10
SO 5: Development and Testing of an Sr
Testing
When food deprived (MO):
R (any response) ----> Sr (click)
*If R increases in frequency, the NS has become an Sr
Critical features:
1. The Sr follows the response (operant relation)
2. The Sr is presented alone (not with the SR)
3. The R must increase in frequency in the future
4. The Sr must occasionally be paired with the SR
(*essential - if the R doesn’t increase, no reinforcer, click critical features)
11
SO5: Sample test question
Assume that a direct care worker wants to use the sound
of a bell as an Sr to increase the extent to which an
autistic child touches a toy.
A. Diagram what the staff member should do to make
the bell into an Sr, labeling all parts of your diagram
with the correct behavioral terms.
To solve:
1. What is the NS?
2. What do you pair it with?
12
SO5: Sample test question
Assume that a direct care worker wants to use the sound
of a bell as an Sr to increase the extent to which an autistic
child touches a toy.
B. Now diagram what the staff member should do to
make sure the bell is an Sr, labeling all parts of your
diagram with the correct behavioral terms.
To solve:
1. What is the response?
2. What is the Sr?
3. Do Srs come before or after responses?
4. To prove a stimulus is a reinforcer, what must
happen to the response?
(another example is in the SOs)
13
SO6: Difference Between
Respondent Conditioning and Development of an Sr
The confusion: Both involve pairing an NS with another
stimulus
Difference:
Respondent
Conditioning:
NS/US, or NS/CS
Development
of an Sr:
NS/SR, or NS/Sr
(Respondent conditioning: NS becomes a CS-->CR; Sr NS becomes Sr; R-->Sr)
14
SO7: Respondent Conditioning &
Development of an Sr
Elephant: Click became an Sr
When food deprived:
NS (click)/SR (carrot)
Click became an Sr
Respondent conditioning: Click is also going to become a CS
NS (click) does not elicit salivation
US (carrot)  UR (salivation) yes, elephants salivate
NS (click)/US (carrot)  UR (salivation)
CS (click)  CR (salivation)
(Although separate and distinct, there are times when they occur together)
15
SO7: When both respondent conditioning
& development of an Sr will occur together
• When the NS is paired with a stimulus that is
both a US and SR or a CS and an Sr
• Example of when it won’t happen: Bright light
which elicits pupillary constriction
A. Bright light is a US  UR
B. NS (click)/US  UR
C. Click will become a CS, but not an Sr
16
Behavioral Enrichment in Zoos, intro
• Behavioral interventions designed to improve the well
being and health of captive animals
• Hal Markowitz started this work in the 1970s
• Zoos have a very important function: protection of
endangered species, education of public
– keep humans from destroying natural habitats
– keep humans from killing off species of animals (ivory
tusks or furs)
– protect and preserve species that are endangered due
to disease, natural disasters
(back to an extension of animal training: mother nature ain’t kind – Poling story)
17
Zoos
• Many of us cringe when we think about
zoos – animals in prison
• But over the years, zoos have been
attempting to make life better for the
animals
(but most zoos have come a long way..)
18
SO9: Two popular* things zoos have
tried to make life better for animals
• Make the enclosures more naturalistic
• Add toys, boomer balls
*popular, but ineffective
Neither – terrifically effective – naturalistic enclosures first)
19
SO10: What’s the problem, even
when enclosures are naturalistic?
• Naturalistic enclosures sometimes do have
some benefits for the animals
• Certainly make us more comfortable
20
SO10: What’s the problem, even
when enclosures are naturalistic?
• Fail to include the behavioral contingencies in the wild that
reinforce species typical (and active) behavior
• Much of the behavior of free-ranging animals involves getting
food (the only one mentioned by Chance), fighting off or
fleeing predators, natural migration, securing mates and
mating, establishing social hierarchies, etc.
• It’s the consequences of those behaviors that maintain much
of the active behavior of wild animals
– some behavior is, of course, genetic
– over the years, they have discovered, however, that many behaviors
that were once considered inherited are learned
(most groups, dominant male: stallions, mares; gorillas; ducklings following Mom
closeness to object, following in the natural environment, bird’s songs)
21
SO10: What’s the problem, even
when enclosures are naturalistic?
• In zoos, food is provided usually in the same place at the same
time each day, animals are completely protected from
predators, certainly cannot migrate to different locations, and
are not subjected to threats of their domination from outside
animals
• There is “no reason” for animals to be active
• Behaviorally the reason to be active:
R (species typical behaviors)  SR (food or other reinforcers)
• What happens if behaviors are not followed by reinforcement?
(in a zoo, no one wants to see an antelope/Bambi killed, mauled, and eaten by a hyena)
22
Great enclosures,
but no reinforcement
for active behaviors
Toys and boomer
balls, but no
reinforcement for
playing with them
23
SO11: Examples of Behavioral
Enrichment
• Servals
(Who can’t love a face like this? Click…Servals swim in the wild; naturalistic
enclosures included ponds – servals didn’t’ swim. Guess what was missing?)
24
Enrichment for Servals:
Honolulu Zoo
Species typical behavior: swimming with same
reinforcement as in the wild, fish
(not squirmish about dead fish; only dead mammals; click; 5-gallon ice, cross-species)
25
Enrichment for Elephants: Honolulu Zoo
Species typical behavior: manipulating objects with
trunk with the same reinforcement as in the wild, food
(variation on the same theme: elephant keggers; not beer!)
26
Enrichment for Langor Monkeys:
Honolulu Zoo
Species typical behavior: grooming and foraging
with reinforcement, food, but in this case fruit loops
(mop head on bungee cord, laced with fruit loops, last slide on this)
27
Markowitz Article: SDs and S∆s
• Definitions: SDs and S∆ (not for the exam)
• My definition of an SD for this class (in SO14):
A stimulus that precedes a response and evokes that
response because that particular response has been
reinforced in its presence and not in its absence.
• Malott’s definition:
A stimulus in the presence of which a response has been
reinforced or punished.
• Pietras’ definition:
An event that precedes an operant and sets the occasion for
the behavior. They change the probability of behavior based
on a history of differential reinforcement.
28
SO15: Development and Testing of an SD
Development/Training: dolphin to jump and back flip
immediately after seeing a hand signal but not in its absence
SD (hand signal):
R (jump and back flip) --->SR (food)
S∆ (no hand signal): R (jump and back flip) --->Ext (no food)
Testing: After repeated SD and S∆ training above, will the
dolphin jump and do a back flip ONLY after the hand signal?
SD (hand signal):
R (jump and back flip)
S∆ (no hand signal):
NO R (does not jump/back flip)
(both SD and S∆ training necessary; reinforcing behavior after SD; MO must be present both)
(Testing done under extinction; Note carefully no ext in s∆ testing)
29
SO15: SD/S∆ Another Example
Training: How do you train a rat to press a lever immediately
when a light is on and ONLY when the light is on.
Testing: After training, how do you test to make sure
The rat presses the lever ONLY after the light on?
30
SO15: Sample test question
• Sample test question is at the end of SO15
• Answer is at the end of the study objectives
for this unit
31
SO16: SDs precede responses,
not other stimuli
• Traffic light: A yellow light is not an SD for a
red light.
• Railroad crossing: The flashing red lights
and bells are not an SD for the crossing
gates coming down.
32
SO17: Evocative vs. Function-altering Effect
• Evocative effect
An environmental event produces an
immediate change in the behavior that
lasts only as long as that event is present
– Change may be a change in latency, magnitude,
or frequency
• Events that have evocative effects
– SDs and S∆s
– Motivating operations (i.e., food deprivation)
(one more technical SO before moving on, that I hope will help you distinguish between and clarify the difference between
antecedent environmental events, and as it relates to this unit, SDs/Sdeltas, and consequences; correct the error that
Many students still make at your level, SDs and Sdeltas increase/decrease the likelihood of a response in the future)
33
SO17: Evocative vs. Function-altering Effect
• Function-altering effect
An environmental event produces a
relatively permanent change in behavior
so that the organism responds differently in
the future
• Events that have function-altering effects
– All operant consequences
(I am only going to focus on the operant relations: SDs, Sdeltas vs. consequences, but corresponding distinction in
respondent relations as well; changes due to reinforcement will persist until response is extinguished/punished; CS
will continue to elicit the response unless respondently extinguished)
34
NFE: Brain Teaser
• What does Michael mean by
– “An SD evokes behavior because of previous
function-altering effects.”
– “Reinforcement conditions a new evocative
relation.”
Hint: Go back and review SO15, ppt slide #29,
the development of an SD and S∆
(I will come back to this at the end of class, if time)
35
NFE: Another Brain Teaser
Evocative vs. Function-altering effects:
Respondent relations
• Give an example of a respondent evocative
effect
• Now, give an example of a respondent
function-altering effect
(I will come back to this at the end of class, if I have time)
36
SOs 18 & 19: Markowtiz
• Markowitz was the behavior analyst who
started behavioral enrichment in zoos
• It has taken almost 40 years for this to gain
traction
• Altered the entire animal training field
– Husbandry
– Behavioral enrichment for health and exercise
– Conservation
37
SOs 18 & 19: Markowtiz
• Dept. of Biology
San Francisco State
• Behavioral Enrichment in
Zoos (1982)
– Launched global movement to
improve conditions of captive
animals in zoos, aquariums,
and biomedical facilities
• Hal Markowitz Fellows:
research funded positions
(one of his mentees, David Bocian is VP animal care, wellness initiative)
(Died 2012, 78 years old)
38
SOs 18 & 19: Review of Behavioral Chains
• Sequence of stimuli and responses:
SD1: R1  Sr/SD2: R2  Sr/SD3: R3  Sr/SR
• The stimulus that follows each R is an Sr for that
response and an SD for the next response
SD1: R1  Sr/SD2: R2
• Each stimulus-response-reinforcer “unit” is
called a link
– The last link is called the terminal link
• In the above chain it would be SD3: R3  Sr/SR
39
Simple Chain with Rat
SD1 (light on): R1 (press lever)  Sr/SD2 (buzzer): R2 (pull chain)  SR (food)
•
•
•
•
•
•
•
Identify one link in this chain.
What is the terminal link in this chain?
What is the reinforcer for the lever press?
What is the SD for pulling the chain?
The buzzer is an Sr for what behavior?
The buzzer is an SD for what behavior?
The buzzer has also become a CS: For what behavior?
(last 5 questions the same ones I ask about the diana monkey chain in SO18)
(TAs may confirm your answers, but they cannot tell you what the answers are;
and we will not answer any questions about this right before the exam)
40
Simple Chain with Rat
SD1 (light on): R1 (press lever)  Sr/SD2 (buzzer): R2 (pull chain)  SR (food)
• What behavior is reinforced when SD1 is present?
• What is the reinforcer for pressing the lever?
• Given the answer above, how would you extinguish
the lever press when the light is on?
• When there is an SD1, there must be an S∆1
– What is it?
– What behavior was extinguished when S∆1 was present?
– How was the behavior extinguished?
(Now, I am going to ask the same questions I ask in SO19 re mandrill I want
to play game; how/why does the buzzer become an Sr?)
41
SO18: Diana Monkey Token Economy
42
SO18: Diana Monkey Token Economy
Top Platform
SD1: Light on
R1: Pull chain
___________
Middle Platform
SD1: Top light on
Sr/SD2: Bottom light on
R2: Pull chain
Sr/SD3: Token delivered
__________________
Bottom Platform
R3: Put token in slot
SR: Food
________________
(why light on middle platform as SD1? Two chain pulls: specify platform, questions on Sos?)
43
SO18: Diana Monkey Token Economy,
Interesting Family Dynamics (NFE)
• Family group: 16-year old momma, Beulah; 8-year old dad,
Rocky; adolescent and infant
• Beulah never learned how to exchange the tokens for food
• Rocky would regularly share food with Beulah and would let
her sit on the platform with him when he exchanged tokens
for food but….would “unceremoniously” knock the youngsters
off the platform AHHH 
• Beulah: to earn food she would “encourage” the others to
work and would occasionally pull the chain that resulted in
the token (after another one had pulled the top chain), but
would always give the token to one of the others – however,
then she would successfully “steal” the food most of time.
44
SO18: Diana Monkey Token Economy,
Interesting Family Dynamics (NFE)
• When the monkeys were learning, Rocky (the dad) was
allowed to “take over” at his whim and completed the
entire sequence without intrusion
• Once the task was mastered by Rocky and the youngsters,
they would often pull chains for one another, and sit
“patiently” watching other monkeys exchange the token for
food.
45
SO19: Mandrill Game
46
SO19: Mandrill Reaction Time Game
• Zoo patrons could push a “I want to play button” and then
insert a dime to start the game
• The computer lit a “I want to play button” for the mandrills to
push on a random schedule if enough zoo patrons didn’t start
the game, and the computer would play with the mandrills
• One of three square lights would randomly light on the
monkey’s console and on the zoo patron’s console
• The contestant that touches the lighted square first, wins that
round
• The contestant that wins three rounds is the victor
• If the mandrill wins, the mandrill is reinforced with food; if the
human wins, they are rewarded by beating the monkey
47
SO19: Mandrill Reaction Time Game
• The mandrill beats the human more than 70% of the time
• Reaction times of the mandrills due to play with computer is as
fast as .31 seconds!
• Benefits to the zoo
– Popular exhibit with zoo patrons and the media
– Received a lot of money to continue the behavioral enrichment work
• Benefits to the mandrills
– The male mandrill has stopped constantly threatening and chasing his
female companions
– All of the mandrills are more active; they are using more space in the
enclosure (interesting side effect, why?)
– Stereotypic behaviors in the enclosure decreased (again, interesting,
why?)
48
SOs 21-32: Poling et al., intro
• Dr. Poling and his students have been working with an
international organization: APOPO
– Belgian nonprofit based in Tanzania
• Training giant African pouch rats (nicknamed
HeroRATS)
– Detect land mines in sub-Sarahan Africa
– Detect TB in humans in sub-Sarahan African
populations where typical TB testing is too
expensive, too slow, and too inaccurate
– Locate survivors in collapsed structures
(straightforward, but I wanted to introduce you to this work – remain with the animal theme. Basic animal training is
leading to significant global humanitarian work; we often don’t see the direct benefits of solid EAB; gives us another
reason why this type of training is so important and how it can be used to benefit society/culture)
49
SOs 21-32: Poling et al., intro
• Why African pouched rats?
– Excellent sense of smell
– Native to sub-Saharan Africa and therefore are resistant to
local parasites and diseases
– Weigh too little to activate mines or cause further
structural damage to collapsed buildings
– Have relatively long working lives (6 years)
– Smaller and less expensive than dogs
• Operant training (rat lab on steroids!)
– Shaping
– Clicker training
– SD/S∆ training

From the author’s web site:
Consequences are everywhere
Actions have consequences—and being able to
learn from them revolutionized life on earth. It
comes in quite handy for every day life as well.
Ten years in the making, The Science of
Consequences tells a tale ranging from genetics
to neurotransmitters, from emotion to language,
from parenting to politics. Taking an inclusive
systems approach, author Susan Schneider draws
together research lines from many scientific fields
to tell a tale that is epic in scope.
