Modern MovementPsychology as a field is moving
towards a behaviorist approach - or -
Psychology is splitting into traditional and behavioral
![Page 6: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/6.jpg)
Clarifications1. Behaviorism – The school of thought that
research and practice should focus on behaviors.
2. Radical Behaviorism – Skinnerian view is that behaviors could be within the skin. (Coined the term “Private Events”)
![Page 7: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/7.jpg)
Behavior?1. Watson 1924 (Behaviorism) – Behavior is
defined by it’s form – muscle movements and glandular secretions.
2. Skinner 1945 (Radical Behaviorism) – Behavior is anything that operates on the environment.

The Great DebatePsychology has Nature vs Nurture.People argued both sides.Most now fall in the middle and think
the debate is not needed.
![Page 9: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/9.jpg)
The Great DebateIn Philosophy the debate is monist vs
dualist. Monist believe there is one plain of
existence (or conscience).Dualist believe there are two plains of
existence (or conscience).
![Page 10: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/10.jpg)
MonistWas, and is, not a popular view.The ancient Greeks were opposed to it.John Locke’s “An Essay Concerning Human
Understanding” (1689).Locke (Empiricist) believed in a “blank slate”
(Tabula Rasa). Favored Nurture over Nature.
![Page 11: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/11.jpg)
MonistLocke never denied the existence of a second
existence (or conscience).
Was more concerned with what he could physically “feel”. Everything else didn’t matter. “You are a product of your environment.”
![Page 12: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/12.jpg)
MonistLocke’s most popular phrase in America:
“Man... hath by nature a power.... to preserve his property - that is, his life, liberty, and estate - against the injuries and attempts of other men.”
![Page 13: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/13.jpg)
MonistHe would be furious if he ever saw the
American translation:“We hold these truths to be self-evident, that
all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness”
![Page 14: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/14.jpg)
MonistLocke’s thoughts?:
“What is happiness?”“How does one (physically) ‘feel’
happiness?”
![Page 15: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/15.jpg)
DualistThe most popular of the two options.Greeks said “Body and Soul”, but were not
“dualist” per se.Renè Descartes (1641) “Mediations of First
Philosophy” was the first to identify the monist vs dualist debate. He was a complete dualist.
![Page 16: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/16.jpg)
DualistDescartes believed what Locke did (you need
to feel to prove), but only for one plain of existence (which he called matter).
Descartes believed that additional proof was needed for the second plain of existence (which he called mind).
![Page 17: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/17.jpg)
DualistDescartes famously found proof of the
second existence:
“Cogito ergo sum”
![Page 18: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/18.jpg)
DualistDescartes famously found proof of the
second existence:
“Cogito ergo sum”“Think there am”
![Page 19: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/19.jpg)
DualistDescartes famously found proof of the
second existence:
“Cogito ergo sum”“Think therefore am”
“I think, therefore I am”
![Page 20: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/20.jpg)
DualistThinking became Descarte’s “feeling”
within the second plain of existance.
Remains mostly undisputed until the 1920’s when Pavlov decided to study spit.
![Page 21: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/21.jpg)
Monist vs DualistNow the question exist and behaviorism in
the only person standing on the other side.
There reasoning:Occam’s Razor (or the Law of Parsomony)
![Page 22: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/22.jpg)
Philosophy1. Watson (Behaviorism) was a Dualist.
Believed the mind should be separate from everything else
2. Skinner (Radical Behaviorism) was a Monist. Believed the mind followed the same principles as everything else (can be reinforced, etc).
![Page 23: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/23.jpg)
Mind ReinforcementStudies have been done where neurons
have been reinforced for ‘firing’. They were reinforced with serotonin.
Theoretically you can re-map a neuron path using reinforcement.
So we lean towards Skinner’s monism.
![Page 24: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/24.jpg)
What type of behaviorist
are you?
![Page 25: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/25.jpg)
Methodological• Watson• Behaviorism• Dualist• Strong view, but has flaws
![Page 26: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/26.jpg)
Cognitive • Ex Hayes• Cognitive Behavioral• Monist/Dualist?• Emerging fields of studies
![Page 27: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/27.jpg)
Radical• Skinner• Radical Behaviorism• Monist (no skin barrier)• Strong and growing evidence
![Page 28: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/28.jpg)
3 Questions1. Do private events have a place in
ABA?2. Do private events affect our overt
(observable) behaviors?3. Should we attempt to modify private
events?
![Page 29: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/29.jpg)
Answer• 2/3 Forms of Behaviorism says “yes”• Methodological says “no”
• Studies have been conducted that show that despite what you “feel”, private events is an area of growing concern and importance.
![Page 30: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/30.jpg)
Role of Private Events• So now that we resolved that private
events should have a place, let’s attempt question 2:
• Do private event affect our overt behaviors?
![Page 31: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/31.jpg)
Schools of Thought• Methodological (doesn’t matter)• Cognitive (absolutely, yes)• Radical (Maybe, but there is currently
no research methodology to support such claims. It should be considered.)
![Page 32: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/32.jpg)
Radical Research?• Because of these complications, many
radical behaviorist have not made an attempt to study private events.
• Some studies that have focused on overt behaviors have reportedly helped with private events such as “fear”, “anxiety”, and “depression”
![Page 33: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/33.jpg)
Interesting• Most radical behaviorist will readily
consider a private event (such as an emotional state) as a “setting event”.
![Page 34: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/34.jpg)
Cognitive Research?• Cognitive Behaviorist have attempted
to study private events but have yet to secure proper research methodology that is universally accepted. This limits the acceptance of their studies.
![Page 35: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/35.jpg)
Assumptions• Cognitive Behaviorist have to make the
following assumptions:• Private Events operate the same as overt behaviors
(monist)• Private Events (consistently) influence behavior • Private Events can be measured through self-report or
overt behaviors• Individuals comply with instructions for private events
![Page 36: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/36.jpg)
3 Questions1. Do private events have a place in
ABA?2. Do private events affect our overt
(observable) behaviors?3. Should we attempt to modify private
events?
![Page 37: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/37.jpg)
Answer• Assumed: “Yes”• No proof• Currently, no way of gaining proof• We don’t know how it does.
![Page 38: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/38.jpg)
Applying Science• Can we• Should we• Attempt to change a person’s private
events?
![Page 39: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/39.jpg)
Hayes of ACT Fame• Hayes is often one of the
professionals that is mentioned as studying private events.
• Focuses on HOW private events might influence overt behaviors.
![Page 40: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/40.jpg)
Are they needed?• Are private events needs to change
behavior?
![Page 41: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/41.jpg)
Baseball• Coach yells “Visualize yourself hitting
the ball.”• Studies have shown that this will
increase the likelihood of batter connecting with the ball.
![Page 42: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/42.jpg)
3-Term Contingency• Cognitive Behaviorist:• Antecedent : Visualization (private event)• Behavior: Hitting Ball
• Radical Behaviorist:• Antecedent : Verbal SD (overt behavior)• Behavior: Hitting Ball
![Page 43: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/43.jpg)
Limitations• Can we prove that the batter actually
visualized hitting the ball?• How did the batter visualize hitting the
ball and how did it differ from other participants?
• Is it important to know?• To Hayes, it is VERY important
![Page 44: Private Events](https://reader036.fdocuments.in/reader036/viewer/2022081520/56816618550346895dd96695/html5/thumbnails/44.jpg)
Conclusion• There large amounts of speculation about
private events.• Research is lacking, because there is no
way to study it.• I won’t tell you what to believe, but it’s
important to know the information.
