Harry Harlow’s ‘Surrogate Mothers’ and other experiments

Group 1: Terrycloth mother did not provide food.

Group 2: Wire mother provided food.

Isolation of MonkeysIsolation of Monkeys

Partially and Fully isolated monkeysPartially isolated (occasional social contact) –

• Repetitive circling of cages, blank staring, and occasional self mutilation

Total social deprivation (6, 12, 24 months)• 6 months = emotional shock when reintroduced:

rocking and clenching, rare anorexia

• 12, 24 months = “obliterated the monkeys socially”

All isolated monkeys exhibited little to no recovery

Social LearningSocial Learning

Process of altering behavior observing and imitating the behavior of others.

Observational Learning and Cognitive Learning

“Learning would be exceedingly laborious, not to mention hazardous, if people had to rely solely on the effects of their own actions to inform them what to do.”

• Albert Bandura (1977)

Observational LearningObservational LearningObservational LearningObservational Learning

Learning by observing others.

ModelingModelingThe process of observing and imitating a specific behavior.

Vicarious Reinforcement Vicarious Reinforcement You first engage in a behavior because you saw someone else get rewardedDirectly tied to Operant Conditioning

Mirror NeuronsMirror Neurons

Fire both when performing actions and when observing another doing so.

NOVA – Mirror Neurons

ModelingModeling

Follow the Leader: The behavior of others increases the chances that we will do the same thing

Clapping, looking out the window, copying the styles and verbal expressions of our peers

Page 8: Do we need social interaction? Harry Harlow’s ‘Surrogate Mothers’ and other experiments Group 1: Terrycloth mother did not provide food. Group 2: Wire

Observational LearningObservational Learning

Watch someone else perform a behavior, then be able to perform the behavior yourself

Learning a game, dance move, sport

Role ModelsRole Models

Role ModelsDo we chose to be a role model?How important are older siblings?parents? peers?

"I don't believe professional athletes should be role models. I believe parents should be role models.... It's not like it was when I was growing up. My mom and my grandmother told me how it was going to be. If I didn't like it, they said, "Don't let the door hit you in the ass on your way out." Parents have to take better control."

• Sir Charles Barkley

Albert Bandura’s Bobo Doll Experiment

Children were exposed to adults displaying aggression toward a bobo doll, and were then observed in a room filled with toys

What happened?

TV and Violence

Before you turn 18, you will see approx. 18,000 simulated murders on TV & movies

Since the 1960s, more than 3,000 studies have linked television violence to real violence

Results: viewers become

desensitized to violence,

become more fearful

behave more violently

Bandura’s Social-Cognitive Theory

Social-Cognitive Theory applies fundamentals of social learning to personality and behavior choices.

Extinction of Phobias / Disinhibition

Learning that seemingly threatening experiences can be safe

Phobia treatment (counter-conditioning)

Safety of new environment

Application of Social Learning

Bad news – antisocial models may have antisocial effects on children

Good news – prosocial (positive, helpful) models can have prosocial effects

Consistency of words and actions.

Social learning plays a large roleParents are extremely powerful models

Children See, Children Do

Latent (Incidental) Learning

Learning that occurs without knowledge being immediately expressed

Accidental learning that occurs in the process of another behavior

• Setting the table, putting in a light bulb

Knowledge is there, but does not come out until a reinforcer appears

Cognitive MapsE.C. Tolman studied in 1930sTaught rats a maze through repetition, without providing reinforcement (food)Once a reinforcer was presented for completion of the maze, the rats were just as quick to complete as rats which received food upon every completionA mental picture of a place which allows you to navigate to an unseen destination

Formation of Insight

An insight is a new way to organize stimuli or a new approach to solving a problemOnce insight has occurred, no further training is necessary

Wolfgang KohlerChimps with insightPigeon shows insight

Learned HelplessnessCondition in which a person gives up due to repeated failureSeligman’s electric shock dog studiesHiroto’s study of college students (1974)People feel they have no control over environment; success seems more a matter of luck than skill

Learned Laziness - Condition that occurs if rewards come without effort, a person never learns to work.

Martin Seligman on Depression

Learned helplessness is a leading cause of depressionStability

Temporary vs. Stable

GlobalitySpecific vs. Global

InternalityExternal vs. Internal

Behavior ModificationSystematic application of learning principles to change people’s actions and feelings

Involves a series of well-defined steps to change behavior.The success of each step is carefully evaluated to find the best solution for a given situation.

Common in sports training and drug treatment – involves intense drive to become an ideal productModeling, classical conditioning, operant conditioning

Self ControlChanging your own behavior

1. Define the problem specificallyThis can often lead to a change in behavior

2. Behavioral contract

Study HabitsConsiderations: negative emotions, environment, conditioning

Page 23: Do we need social interaction? Harry Harlow’s ‘Surrogate Mothers’ and other experiments Group 1: Terrycloth mother did not provide food. Group 2: Wire

Bad Habits

How are bad habits formed?Procrastination

Favoring immediate reinforcement and accepting delayed punishment

Page 24: Do we need social interaction? Harry Harlow’s ‘Surrogate Mothers’ and other experiments Group 1: Terrycloth mother did not provide food. Group 2: Wire

Token Economies

Desirable behavior is reinforced with valueless objects, which can be accumulated and exchanged for valued rewards

Used most commonly in prisons, mental hospitals

Combats attention as reinforcement drawback

Does this result in long term learning?
