Behavioral Genetics, Evolutionary Psychology, & Behavior

36m 10s

Intro

0:00

Behavioral Genetics

0:11

Objective: Discuss Psychology's Abiding Interest in How Heredity, Environment, and Evolution Work Together to Shape Behavior

0:16

What Influences do our Genetics Have on Our Behavior, Both as an Individual, as Well as in Groups?

0:24

Nature Versus Nurture

0:34

Nature Refers to Heredity, a Person's Biological Makeup

0:38

Nurture Refers to the Environment, a Person's Life Experiences, Family and Education

0:45

Heredity

0:58

Developmental Psychology: The Study of Progressive Changes in Behavior and Abilities

1:01

Heredity (Nature): Transmission of Physical and Psychological Characteristics From Parents to Their Children Through Genes

1:15

DNA (Deoxyribonucleic Acid): Molecular Structure Shaped Like a Double Helix That Contains Coded Genetic Information

1:25

Genome: The Entirety of an Organism's Hereditary Information (Includes Info Coded in DNA or RNA)

1:49

Genes

2:17

Genes: Specific Areas on a Strand of DNA That Carry Hereditary Information

2:23

Genetic Makeup

2:46

DNA (Deoxyribonucleic Acid) is the Means by Which Heredity Characteristics Pass From One Generation to the Next

2:49

Fraternal Twins are Dizygotic Twins That Develop From the Union of Two Separate Sperms and Eggs

3:06

Identical Twins are Monozygotic Twins That Develop From the Union of the Same Egg and Sperm That Have Split and Have Exactly the Same Genotype (May Have the Same Genes, But Not Necessarily the Same Number of Copies of Those Genes)

3:28

Genetic Building Blocks

4:13

The Human Body Contains 100 Trillion Cells

4:16

There is a Nucleus Inside Each Human Cell (Except Red Blood Cells)

4:27

Each Nucleus Contains 46 Chromosomes, Arranged in 23 Pairs

4:34

One Chromosome of Every Pair is From Each Parent

4:49

The Chromosomes are Filled With Tightly Coiled Strands of DNA.

4:53

Genes are Segments of DNA That Contain Instructions to Make Proteins -- The Building Blocks of Life

4:59

Chromosomes

5:08

Picture of What is Inside a Chromosome

5:10

DNA

5:47

Linked Molecules (Organic Bases) Make Up the Rungs on DNA's Twisted Molecular Ladder. The Order of These Molecules Serves as a Code for Genetic Information

5:49

The Code Provides a Genetic Blueprint That is Unique for Each Individual (Except Identical Twins). The Drawing Shows Only a Small Section of a DNA Strand. An Entire Strand of DNA is Composed of Billions of Smaller Molecules

6:04

The Nucleus of Each Cell in the Body Contains Chromosomes Made up of Tightly Wound Coils of DNA.

6:25

Don't be Misled By the Drawing: Chromosomes are Microscopic in Size, and the Chemical Molecules That Make Up DNA are Even Smaller

6:41

Gene Patterns: Eye Color

7:01

Dominant and Recessive Traits

7:09

Gene Patterns for Children of Brown-Eyed Parents, Where Each Parent has One Brown-Eye Gene and One Blue-Eye Gene

7:12

Because the Brown Eye Gene is Dominant, One out of Every Four Children Will Be Blue-Eyed

7:22

There is a Significant Chance That Two Brown-Eyed Parents Will Have a Blue-Eyed Child

7:29

Dominant Recessive

7:43

Graphic Depicting All the Eye Color Combinations a Brown-Eyed Mother and Brown-Eyed Father Could Have

7:44

Temperament and Environment

9:53

Temperament: The Physical Core of Personality; Includes Sensitivity, Irritability, Distractibility, and Typical Mood

9:56

Easy Children: 40% Relaxed and Agreeable

10:09

Difficult Children: 10% Moody, Intense, Easily Angered

10:26

Slow-to-Warm-Up Children: 15% Restrained, Unexpressive, Shy

10:38

Remaining Children: Do Not Fit Into Any Specific Category

10:55

Environment

11:09

Environment (Nurture): All External Conditions That Affect a Person, Especially the Effects of Learning; the World Around a Person.

11:14

Sensitive Periods: A Period of Increased Sensitivity to Environmental Influences; Also a Time When Certain Events Must Occur for Normal Development to Take Place

11:27

Prenatal Issues

13:10

Congenital Problem: A Problem or Defect That Occurs During Prenatal Development; Birth Defect

13:14

Genetic Disorder: Problem Caused by Inherited Characteristics From Parents; e.g. Cystic Fibrosis, Neurofibromatosis

13:23

Website Link to Information on Genetic Disorders

13:56

Twin and Adoption Studies

14:14

Some Research Conclusions

14:19

Shared Genes Can Also Mean a Shared Experience -- Most, Not All, Identical Twins Share Placentas

14:25

A Person Whose Identical Twin Has Alzheimer's Has a 60% Chance of Getting It; Fraternal Twin, Only 30%.

14:44

On Extraversion and Neuroticism (Emotional Stability), Identical Twins are More Alike Than Fraternal Twins

14:58

Divorce -- If Fraternal Twin Divorced, Your Odds Increase 1.6 Times; If Identical Twin Divorced, Odds Go Up 5.5 Times

15:24

The Jim Twins

16:03

Separated at Birth -- Reconnected After 38 Years

16:09

Both Named Jim (Lewis and Springer)

16:13

Both Liked Woodworking, Driving their Chevy Cars, Watching Stock-Car Races, and Drinking Miller Lite.

16:19

Both Had Nearly Identical Voices

16:28

Personalities, Intelligence, Heart Rates and Brain Waves -- Nearly Identical

16:35

It Would Seem Genes Had a Profound Impact on Personality -- But the Question Remains to This Day -- Just How Much?

16:40

But This is Anecdote, What About Real Data?

16:52

Big Conclusion

17:00

The Environment Shared By A Family's Children Has Virtually No Identifiable Impact on Personalities of Children

17:04

But Why? Geneticists Are Working on It.

17:12

But What About Family Life?

17:47

So, The Question For You -- Would You Be the Same Person if You Had Been Raised in a Different Family or Culture?

17:56

Heritability

18:32

The Proportion of Variation Among Members of a Group That We Can Attribute to Genes

18:40

So This Compares, Within Populations, Genotypes (Genetic Makeup) and Phenotypes (The Outward, Physical Manifestation of the Organism) on Specific Traits

19:14

This Difference Involves Mathematics and Analysis That is Far Beyond This Course -- Take AP Bio or Genetics for Mendelian Genetics

19:34

Heritability

20:00

It is Not Behaviors That Are Inherited, But Genetic Predispositions That May Lead to the Behavior

20:03

Heritable Differences Between Individuals Does Not Imply Heritable Group Differences

21:23

Genes and Interaction

21:43

Interaction: The Interplay When the Effect of One Factor (Such as Environment) Depends on Another Factor (Such as Heredity)

21:47

Genes and Environment Work Together (Like Two Hands Clapping). Genes Code for Proteins But Also Respond to Environments

21:55

Example: Happy Baby Draws in More Adults Who Respond to the Happiness With Warmth of Their Own -- This Can Become a Cycle, With the Happy Baby Becoming More Outgoing and Socially Confident

22:39

This Kind of Interaction Can Be Applied to Virtually Any Trait, Especially Anxiety and Depression

23:17

Natural Selection and Adaptation

24:20

Only the Strong Survive is a Myth -- It's the Ones With the Most Adaptive Traits For Their Environment

24:25

Evolutionary Psychology: The Study of the Evolution of Behavior and the Mind, Using Principles of Natural Selection

24:42

Natural Selection: The Principle That, Among the Range of Inherited Trait Variations, Those That Lead to Increased Reproduction and Survival Will Most Likely Be Passed on to Succeeding Generations

24:55

Mutation: The Random Error in Gene Replication That Leads to Change

25:35

Evolutionary Psychology

25:50

Evolutionary Success Helps Explain Similarities Among People

25:54

However, We Have Some Outdated Tendencies -- Some Genetic Traits That Were Previously Helpful May Harm Us Today

26:42

Evolutionary Psychology, Continued

28:07

Examines Psychological Traits Such as Memory, Perception and Language Using Modern Evolutionary Perspective

28:10

Which Human Psychological Traits Are Evolved Adaptations -- That is, The Products of Natural or Sexual Selection?

28:18

Examples Could Include an Ability to Infer Emotions of Others, Discern Kin From Non-Kin, Identify and Prefer Healthier Mates, and Cooperate With Others

28:27

Sexual Adaptations

29:47

Both Men and Women Looking For Signs of a Healthy Potential Mate

4:30

Influenced Psychophysics

4:34

Studied Weight Perception and How There was a Proportional Relationship Between Increase of Magnitude of Weight and Ability to Make the Discrimination Between the Weights(Fechner Later Called it Weber's Law)

4:36

Weber-Fechner Law -- Ratio of Intensity to Have a Just Noticeable Difference (JND)

5:51

Studied Absolute Thresholds -- Our Awareness of Faint Stimuli

6:13

Gustav Fechner

6:29

Influenced Modern Experimental Psych

6:31

Founder of Psychophysics

6:34

Studied Absolute Thresholds -- Our Awareness of Faint Stimuli

6:36

Illustrated the Non-Linear Relationship Between Psychological Sensation and Physical Intensity of a Stimulus

6:43

Weber-Fechner Law -- Ratio of Intensity to Have a Just Noticeable Difference

7:19

Sensory Transduction

7:32

Conversion of One Form of Energy Into Another. In Sensation, The Transforming of Stimulus Energies, Such as Sights, Sounds, and Smells Into Neural Impulses Our Brains Can Interpret.

7:40

Absolute Threshold

8:22

The Minimum Stimulation Necessary to Detect a Particular Stimulus 50% of the Time

8:26

Exploited by Students Who May Use the Mosquito Ringtone to Evade Phone Use in Class

8:44

Vision -- Candle Flame Seen at 30 Miles on a Clear Dark Night

9:20

Hearing -- Tick of a Watch Under Quiet Conditions at 20 Feet (The Buzz of the Fluorescent Lights in a Quiet Room)

9:51

Taste -- One Teaspoon Sugar in 2 Gallons of Water

10:28

Smell -- One Drop Perfume Diffused Into a Three-Room Apartment

10:42

Touch -- A Bee's Wing Falling On Your Cheek from One Centimeter Above.

10:57

Difference Threshold

11:11

The Minimum Difference Between Two Stimuli Required for Detection. We Experience the Difference Threshold as a Just Noticeable Difference (JND).

11:14

The Detectable Difference Increases With the Magnitude -- is Done in a Constant Proportion

11:32

E.g. You Will Notice is One Ounce is Added to a 10 Ounce Weight, But Not if One Ounce is Added to a 100-Ounce Weight

11:38

Volume on the Television

12:11

Weber's Law

12:40

The Principle That, to be Perceived as Different, Stimuli Must Differ by a Constant Percentage (Rather Than a Constant Amount)

12:43

The Amount of Change Needed to Produce a Constant JND is a Constant Proportion of the Original Stimulus Intensity

12:56

Signal Detection

13:21

A Theory Predicting How and When We Detect the Presence of a Faint Stimulus (Signal) Amid Background Stimulation (Noise).

13:27

Assumes There is no Absolute Threshold and that Detection Depends Partly on a Person's Experience, Expectations, Motivation, and Alertness

13:38

Separating the Music From the Noise or the Signal From the Noise

13:53

Important Info Versus Background and Irrelevant

14:04

Sensory Adaptation

15:47

AKA Neural Adaptation

15:54

Neural or Sensory Receptors Change/Reduce Their Sensitivity to a Continuous, Unchanging Stimuli

16:04

This Occurs in the Brain at an Unconscious Level

16:11

E.g. The Smell of Your Own Car or Home

16:22

E.g. Adapting to Hot or Cold Water After a Brief Time in It.

17:12

E.g. The Eyes Adjusting to a Darker Room -- Rods and Cones Will Fire Differently to Adjust (Cones Take About 10 Minutes, the Rods 30 Minutes to Fully Adapt)

17:39

Why Certain Foods Do Not Taste the Same on the 20th Bite as They Did on the First

18:24

In Economics, This is Diminishing Marginal Utility

19:05

NOT The Same as Habituation (We Will Go Over That Later)

19:31

Top-Down Processing

19:42

Information Processing Guided by Higher-Level Mental Processes, as When We Construct Perceptions Drawing on Our Experience and Expectations

19:45

People Look at the Big Picture, the Whole, Try to Find Patterns to Make Meaning and Then Examine the Details (We Use Background Knowledge to Fill Gaps)

20:03

The Stroop Effect Was One Experiment That Dealt With This

20:18

Deductive Reasoning

21:54

Even Though the Second Letter in Each Word is Ambiguous, T-D Processing Allows for Context to Clarify For Us

22:03

Bottom-Up Processing (AKA Feature Analysis)

22:47

Analysis That Begins With the Sensory Receptors And Works Up to the Brain's Integration of Sensory Information

22:55

Works From the Details and Moves Out to the Whole Picture

23:06

Inductive Reasoning -- Going From the Examples First and Working One's Way Out to the General Propositions -- Uses Probabilities Based Upon Specific Observations

23:17

Based Upon Current Knowledge, So Potentially Biased (e.g. Confirmation Bias, Availability Heuristic, Illusory Correlation)

23:39

e.g. Since 100% of Bio Life Forms Depend on Liquid Water to Exist, if We Were to Discover a New Bio Form, It Will Probably Depend on Liquid Water to Exist

A Mental Disposition to Perceive One Thing and Not Another

32:03

This Goes Back to the Simon and Garfunkel Song

34:32

Perceptual Set -- Culture and Context Effects

Theories of Sound/Hearing

9:10

How Do We Hear Certain Pitches or Tones

9:14

Place Theory Says That Hair Cells in the Cochlea Respond to Different Frequencies of Sound Based Upon Where They Are in the Cochlea

9:19

Pitch Theory Indicates That Some Hair Cells Sense the Upper Range and Some Hair Cells Respond to the Lower Range.

10:00

Lower Tones are Sensed By the Rate at Which The Cells Fire. We Sense Pitch Because the Hair Cells Fire at Different Rates (Frequencies) in the Cochlea

10:08

Auditory Frequencies of Humans

10:29

Audible Range of Frequencies is Usually 20-20,000 Hz.

10:43

This Means 20 to 20K Vibrations Per Second

11:05

One Hertz is One Vibration Per Second

11:11

Ultrasound (Higher Frequency) -- We Cannot Perceive -- Beyond Our Upper Limit (e.g. Dog Whistle and Bats With Echolocation)

11:22

Infrasound (Lower Frequency) -- We Can Not Perceive

14:44

Diagram of Hearing Continuum -- What Humans Can and Can Not Hear

14:50

How Do We Detect Higher and Lower Sounds?

17:02

Frequency Theory: As Pitch Rises, Nerve Impulses of a Corresponding Frequency Travel Up the Auditory Nerve That Matches the Frequency of the Tone

17:12

This Enables Us To Perceive Pitch

17:22

Place Theory: Higher and Lower Tones Excite Specific Areas of the Cochlea -- See Previous Graphic

17:26

Examples: Singing and Pitch -- The Film Pitch Perfect Singing A Capella

24:28

Visceral Pain: Pain Originating in Internal Organs

24:38

Referred Pain: Pain Felt on Surface of Body, Away from Origin Point

24:50

24:55

Phantom Limb: Missing Limb Feels Like It is Present, Like Always Before Amputation or Accident (V.S. Ramachandran's Work Phantoms in the Brain)

25:14

Types of Pain

26:51

Warning System: Pain Carried by Large Nerve Fibers; Sharp, Bright, Fast Pain That Tells You Body Damage May Be Occurring (e.g. Knife Cut)

26:57

Reminding System: Small Nerve Fibers: Slower, Nagging, Aching, Widespread; Gets Worse if Stimulus is Repeated; Reminds System That Body has Been Injured

27:29

Gate-Control Theory of Pain

28:16

Sensory (Afferent) Receptors That Respond to Damaging Tissue (or Other Noxious Stimuli) Are Pain Receptors or Nociceptors

28:21

The More the Neurons Fire, The More Intense the Pain

28:38

Theory That Pain Messages From Different Nerve Fibers Pass Through the Same Neural Gate in the Spinal Cord

28:42

If Gate is Closed by One Pain Message, Other Messages May Not be Able to Pass Through

28:50

Substance P is a Neuropeptide (regulatory) Neurotransmitter -- Along With Other NTs Can Increase Neural Inflammation

29:38

Adaptation, Attention, and Sensory Gating

34:35

If You Can Regulate a Painful Stimulus, You Have Control Over It

34:46

Distraction Can Also Significantly Reduce Pain

35:07

The Interpretation You Give A Stimulus Also Affects Pain

13:10

Drugs That Reduce Anxiety or Induce Sleep

13:11

Also Called Tranquilizers or Hypnotics

13:20

Drugs That Depress Neural Activity, Temporarily Lessen Pain and Anxiety

14:40

Include: Opium, Morphine, Codeine, and Heroin

14:54

Strong Sedative and Pain-Relieving Drugs

15:31

Work By Preventing Pain Neurons From Firing or Releasing Pain-Signaling Neurotransmitters Into the Synapse, and Increasing Endorphin Levels

15:35

Over Time, the Brain Eventually Stops Producing Its Own Endorphins (Endogenous Opioid Peptides)

15:48

Blocks Neurological Receptor Sites That, If Activated, Sedate the Central Nervous System

19:08

All Stimulants Can Cause Dependence, Tolerance, Withdrawal, and Psychological Addiction

19:30

Methamphetamines = Super Stimulant

19:55

Stimulants -- Cocaine

20:50

Sniffed/Snorted, Injected or Smoked -- Gets Into Bloodstream Quickly

20:51

Euphoria Created Depletes Brain's Supply of Dopamine, Serotonin, and Norepinephrine

21:00

Crack is More Potent Version -- Briefer, More Intense High, a Craving for More

21:40

Cocaine is a Reuptake Inhibitor -- This Means it Blocks Neurotransmitters Already in the Synapse

21:52

Once Cocaine Level Drops, There is a Crash

22:33

Stimulants -- MDMA

22:42

Ecstasy, Molly -- Methylenedioxymethamphetamine

22:43

First Used in Northern California in Therapists' Offices

3-4 Hour Impact

24:16

Lower Inhibitions, Increases Pleasant Feelings, and Greater Acceptance of Others Increased Light and Tactile Sensitivity

24:23

Dehydrating Effect (Made Worse by Dancing), Overheating, Increased Blood Pressure, and Even Death

25:37

Suppresses Immune System, Impairs Memory, and Disrupts Sleep (Part of Serotonin Connection)

26:18

Many Have a Near Death Type of Experience -- Related to Oxygen Deprivation

28:00

Can Cause Physiological Dependence/Tolerance in Some People, But Not Everyone. Can Cause Psychological Dependence

28:07

Marijuana

29:41

Leaves, Stems, Resin, and Flowers From the Hemp Plant That, When Smoked, Lower Inhibitions and Produce Feelings of Relaxation and Mild Euphoria

29:42

THC (Delta-9-Tetrahydrocannabinol) is the Active Ingredient

4:11

In This Unit, We Will Examine Learning By Association by Consequence and By Observation

4:36

Lots of Terms and Relationships to Each Other

4:41

Learning is Inferred From a Change in Behavior/Performance

4:59

Learning Results in an Inferred Change in Memory

5:09

Learning

5:22

This Means That Behavior Changes That are Temporary or Due to Things Like Drugs, Alcohol, etc. are NOT Learned

5:29

Classical Conditioning

5:46

One Type of Learning

6:19

Learning That Takes Place When an Originally Neutral Stimulus Comes to Produce a Conditioned Response Because of its Association With an Unconditioned Stimulus.

6:23

History: Discovered by Russian Psychologist, Ivan Pavlov.

7:56

Studied Dogs and Salivation

8:01

Pavlov and Contiguity

8:34

Temporal Association Between Two Events That Occur Closely Together in Time.

8:58

The More Closely in Time Two Events Occurred, the More Likely They Were to Become Associated; as Time Passes, Association Becomes Less Likely

9:28

Terms

10:22

Unconditioned Stimulus (UCS or US) -- Any Stimulus That Creates an Autonomic/Automatic/Reflexive Response in an Organism

10:27

Unconditioned Response (UCR or UR) -- Response That Occurs Due to Autonomic or Reflective Stimulus

10:52

Conditioned Stimulus (CS) -- Anything That Can Be Perceived

11:10

Conditioned Response (CR) -- Anything That Can Be a UCR/UR Can Become a CR. For AP Psych, the UR is ALWAYS the Same as the CR

11:26

Beer Ads

2:02

Attractive Women (UCS) --> Arousal (UCR) then Attractive Women + Beer (CS) --> Eventually Becomes Beer --> Arousal

2:08

Crime Example

2:52

When a Professor Was in College, He Was Robbed at Gun Point by a Young Man Who Gave Him the Choice (Your Money or Your Life) It was an Unexpected and Frightening Experience

2:55

This Event Occurred At Just About Dusk and for a Long Time Thereafter, He Often Experienced Moments of Dread in the Late Afternoons Particularly When He Was Just Walking Around the City

3:05

Even Though He Was Quite Safe, The Lengthening Shadows of the Day Were So Strongly Associated With the Dear He Experienced in the Robbery, That He Could Not But Help Feel the Emotion All Over

3:16

Label the Crime Experience

4:15

Threat (UCS) --> Fear (UCR) then Dusk + Robbery Became Dusk (CS) --> Fear (CR)

4:17

Alcoholism

4:56

Another Way to Treat Alcoholics is to Have Them Take a Drug Called Antabuse (Disulfiram). If They Ingest Any Alcohol at All, They Will Have Serious Vomiting Issues. The Desire is to Pair the Vomiting With the Alcoholic Drink.

4:58

Can You Label the Diagram?

5:19

Antabuse Example

6:19

Antabuse (UCS) --> Vomiting (UCR) then Alcohol + Antabuse (CS) Eventually Becomes Alcohol --> Vomiting (CR) (But WITHOUT Use of Antabuse)

10:03

Stimulus Generalization and Discrimination

10:21

Stimulus Generalization

10:24

Applies Learning to Similar Things to What Was Associated

10:27

Stimulus Discrimination

10:58

Does NOT Apply Learning to Similar Things To What Was Associated -- Responds Only to the Original Association

11:00

Glaucoma Test

11:36

Opticians and the Puff Machines -- How My Chin Made Me Cry

11:58

Air Puff (UCS) --> Eyes Watering (UCR) then Air Puff + Chin Cup Eventually Becomes Chin Cup --> Eyes Watering

13:02

Extinction and Spontaneous Recovery

13:33

Extinction

13:37

A Procedure That Leads to the Gradual Weakening And Eventual Disappearance of the CR.

13:40

Involves Repeatedly Presenting the CS Without Pairing it With the UCS.

13:50

Spontaneous Recovery

15:09

Occurs When a Previously Extinguished CR Reappears After a Period of No Training

15:12

Will Often Result From Non-Recognized Factors Not Previously Identified

15:24

The (John) Garcia Effect

15:51

This is the Conditioned Taste Aversion That is Rapidly Achieved by a Single Pairing of an Illness Such as Nausea With Eating a Specific Food

16:36

Originally Discovered While Working With Rats and Studying Radiation Effects -- Initial Exposure to Food Followed by Toxic Reaction (Even if Several Hours Later) Made Rats Averse to Food

17:18

Conditioned Animals to Avoid Foods Paired With a Previously Aversive Taste

17:35

Conditioning Applied to Tastes But Not to Sights and Sounds

17:44

Process Not Traditional CS --> UCS --> CR/UCR Process Since CS Occurred Long Afterward, Not Immediately

17:53

Taste Aversion in Chemotherapy Patients is Very Common

18:07

Higher Order (Second Order) Conditioning

18:40

Starts Off With Traditional Unlearned Stimulus-Response Relationship, With First Association Pairing Made But Then a Second Association is Introduced

18:47

Ex: Training Involving a Tone Then Adding Light as Second Association

Thorndike and the Law of Effect

1:07

Responses That Produce a Satisfying Effect in a Particular Situation Become More Likely to Occur Again in That Situation, and Responses That Produce a Discomforting Effect Become Less Likely to Occur Again In That Situation

1:20

In Other Words, When Better Things Happen After We Do Something, We Are More Likely to Do It Again

1:36

Connectionism -- Organisms Connect Behaviors to What Occurs After -- Early Form of Behaviorism

1:46

Thorndike is Father of Modern Educational Psychology

After Many Trials in Box, Cat is More Likely to Push Release Lever First to Escape Box.

3:56

B.F. Skinner

4:17

Founder of Modern Behavioral Perspective

4:20

Operant Conditioning -- An Organism Operates in Its Environment, Exhibiting Behaviors That are Inborn or Learned

4:32

Environmental Determinism

5:17

Invented the Operant Conditioning Box -- Sometimes Called a Skinner Box -- He Hated That Term

5:28

Trained Rats, Birds, and People

5:40

So Much Research in This Area -- One of the Most Scientifically Validated Theories/Approaches

5:55

Operant Conditioning

6:09

A Type of Learning in Which Behavior is Strengthened if Followed by a Reinforcer or Diminished if Followed by a Punisher

6:11

What We Are Trying to do is Learn How We Can Modify an Organism's Behavior Using the Most Effective Means Possible. We Use Reinforcement and Punishment. Each Organism Interprets This Differently.

6:27

Key Distinction in Terms -- in OC, The Organism EMITS Behavior. In CC, The Behavior is ELICITED (Drawn Out of the Organism)

15:46

Positive Reinforcement -- Adding a Pleasant Stimulus to Increase a Behavior

15:47

e.g. Getting a Hug

15:57

e.g. Receiving a Paycheck

16:38

e.g. Getting a Great Job! From Coach or Teacher

16:48

There was this Goose -- Tale of Reinforcement

17:16

Negative Reinforcement

20:05

Negative Reinforcement -- Removing an Unpleasant/Aversive Stimulus to Increase a Behavior

20:08

e.g. The Buzzing Stops When You Fasten Seat Belt

20:16

e.g. You Put on Sunscreen Before Getting in the Sun at the Beach

21:22

Punishment

21:38

Positive Punishment -- Adding an Unpleasant/Aversive Stimulus to Reduce a Behavior

21:43

Punishment

23:26

Negative Punishment -- Removing a Pleasant Stimulus to Reduce a Behavior

Kinds of Reinforcement & Punishment

Chart Looking at Positive/Negative (Adding or Removing Stimulus And Reinforcement vs. Punishment

0:16

Escape Conditioning

1:12

Escape Conditioning Occurs When the Animal Learns to Perform an Operant to Terminate an Ongoing, Aversive Stimulus. It is a Get Me Out of Here or Shut This Off Reaction, Aimed at Escape From Pain or Annoyance. The Behavior That Produces Escape is Negatively Reinforced (Reinforced by the Elimination of the Unpleasant Stimulus).

1:15

Avoidance Conditioning

2:52

When an Organism Learns to Avoid Unpleasant or Punishing Stimuli by Learning the Appropriate Anticipatory Response to Protect it From Further Stimuli (Learns a Cue Before the Stimuli -- Follows Escape Conditioning)

2:56

Occurs Quickly and is Very Durable.

3:18

e.g. If You Sounded a Tone Before You Electrified the Platform. After One or Two Trials, the Rat Would Respond to the Tone by Jumping Into the Water. It Would Not Wait for the Shock.

3:53

This is a Form of Stimulus Control, Because it Puts Behavior Under Control of a Stimulus, in This Case, the Warning Tone.

4:08

Avoidance Behaviors are Incredibly Persistent. This is True When There is No Longer Anything to Avoid.

4:15

Schedules of Reinforcement

5:17

Continuous Reinforcement: Every Instance of a Behavior Occurs is Reinforced

5:33

Partial (Intermittent) Reinforcement -- Reinforcing a Response Only Part of the Time; Results in Slower Acquisition of a Response But Much Greater Resistance to Extinction Than Does Continuous Reinforcement

5:44

Ratio Schedules: Reinforcement is Based on the Number of Behaviors Required

6:34

Interval Schedules: Reinforcement is Based on the Passage of Time

6:39

Variable -- Uncertain Number of Times/Behaviors

6:44

Memory, Part II

Maintenance rehearsal is simple repetition of ideas to recall them
Elaborative rehearsal combines the new info with existing memories to help transfer into long term memory
Pseudo-memories are false memories that people believe are true
Procedural memories are related to skills and actions
Declarative memories are related to facts
Semantic memories are related to impersonal facts and everyday knowledge
Episodic memories are related to personal experiences
The serial-position effect shows us that we recall the beginning and end of lists of terms we are trying to recall
Recognition and recall are two ways to show memory—recall is harder due to the lack of external cues
There are many reasons why we forget—disuse, interference, state/mood dependence, lack of cues
