LEARNING

WHAT IS LEARNING?

•Learning is the act of acquiring new or modifying existing knowledge, behaviors, skills, values, or preferences and may involve synthesizing different types of information.

WHAT IS LEARNING?

• It is a relative permanent change in behavior or mental state based on experience.• Learning may occur consciously or

unconsciously.

DEFINITION OF TERMS:

•STIMULUS – it is a external and internal change which generate the response of the body.

•RESPONSE – reaction shown by the body.

TYPES OF LEARNING

• Non-associative Learning – is learning that does not require linking or associating stimuli together.

(Habituation, Sensitization)• Associative Learning – is the process by which an

association between two stimuli or a behavior and a stimulus is learned.

(Classical Learning, Operant Learning)

NON-ASSOCIATIVE LEARNING

• Habituation it is when repeated exposure to a stimulus decreases an organism's responsiveness to the stimulus.

NON-ASSOCIATIVE LEARNING

•Sensitization it is learning that occurs when stimulus is repeated, and each time your response to it increases as it goes on and on

DEFINITION OF TERMS:

•CONDITIONED – learned•UNCONDITIONED -unlearned

ASSOCIATIVE LEARNING

•Classical Conditioning - “Pavlovian” or “Respondent Conditioning”.- It is a learning process in which an innate response to a potent stimulus comes to be elicited in response to a previously neutral stimulus; this is achieved by repeated pairings of the neutral stimulus with the potent stimulus.

THE CLASSICAL CONDITIONING PROCESS

THE CLASSICAL CONDITIONING PROCESS

•Stage 1: Before Conditioning•The Unconditioned Stimulus (UCS)

The unconditioned stimulus is one that unconditionally, naturally, and automatically triggers a response.

THE CLASSICAL CONDITIONING PROCESS

•Stage 1: Before Conditioning•The Unconditioned Response (UCR)

The unconditioned response is the unlearned response that occurs naturally in response to the unconditioned stimulus.

THE CLASSICAL CONDITIONING PROCESS

THE CLASSICAL CONDITIONING PROCESS

• Stage 1: During Conditioning• The Neutral Stimulus

- Another stimulus which has no affect on a person.- NS could be a person, object, place etc.- The NS in classical conditioning does not produce

a response until it is paired with the unconditioned stimulus.

THE CLASSICAL CONDITIONING PROCESS

•Stage 2: During Conditioning•The Conditioned Stimulus•The conditioned stimulus is previously

neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.

THE CLASSICAL CONDITIONING PROCESS

THE CLASSICAL CONDITIONING PROCESS

•Stage 3 : After Conditioning•The Conditioned Response•The conditioned response is the learned

response to the previously neutral stimulus.

DEFINITION OF TERMS:•STIMULUS•RESPONSE•CONDITIONED•UNCONDITIONED•REINFORCEMENT•CONSEQUENCE

ASSOCIATIVE LEARNING

•Operant Conditioning- “Instrumental Conditioning”- It is a learning process in which behavior is

sensitive to, or controlled by its consequences.- It is a type of learning in which behavior is

strengthened if followed by reinforcement or diminished if followed by punishment

ASSOCIATIVE LEARNING

•Operant Conditioning- “Instrumental Conditioning”- It is a learning process in which behavior is

sensitive to, or controlled by its consequences.- It is a type of learning in which behavior is

strengthened if followed by reinforcement or diminished if followed by punishment

THE COMPONENTS OF OPERANT CONDITIONING

•Reinforcement is any event that strengthens or increases the behavior it follows. (Positive Reinforcers, Negative Reinforcers)• In both of these cases of reinforcement,

the behavior increases.

THE COMPONENTS OF OPERANT CONDITIONING

•Positive reinforcers are favorable events or outcomes that are presented after the behavior. In situations that reflect positive reinforcement, a response or behavior is strengthened by the addition of something, such as praise or a direct reward.

THE COMPONENTS OF OPERANT CONDITIONING

•Examples: •A mother gives her son praise (positive

stimulus) for doing homework (behavior).•The little boy receives girfts (positive

stimulus) for every A he earns on his report card (behavior).

THE COMPONENTS OF OPERANT CONDITIONING

•Negative reinforcers involve the removal of an unfavorable events or outcomes after the display of a behavior. In these situations, a response is strengthened by the removal of something considered unpleasant.

THE COMPONENTS OF OPERANT CONDITIONING• Example:

• Before: Hands are wet.• Behaviour: Rub them in the towel.• After: Water is gone from his hands.• Future behaviour: Thomas will rub his hands when they are wet.

THE COMPONENTS OF OPERANT CONDITIONING• Example:

• Before: Carrots on the plate.• Behaviour: Screaming.• After: Carrots no longer on the plate.• Future behaviour: Timmy will scream when he doesn’t want carrots.

THE COMPONENTS OF OPERANT CONDITIONING• Example:

• Before: Piping hot bowl.• Behaviour: Put on oven gloves.• After: Hands are prevented from being burned.• Future behaviour: John will put on oven gloves when taking a hot bowl

out of the microwave.

THE COMPONENTS OF OPERANT CONDITIONING

THE COMPONENTS OF OPERANT CONDITIONING

•Punishment, is the presentation of an adverse event or outcome that causes a decrease in the behavior it follows.

(Positive Punishment, Negative Punishment)• In both of these cases of punishment, the

behavior decreases.

THE COMPONENTS OF OPERANT CONDITIONING

•Positive punishment sometimes referred to as punishment by application, involves the presentation of an unfavorable event or outcome in order to weaken the response it follows.

THE COMPONENTS OF OPERANT CONDITIONING• Examples•An employee exhibits bad behavior at work

and the boss criticizes him. The behavior will decrease because of the boss’s criticism.

• In an experiment, the subject received a slight electric shock when they got an answer wrong.

THE COMPONENTS OF OPERANT CONDITIONING

•Negative punishment, also known as punishment by removal, occurs when an favorable event or outcome is removed after a behavior occurs.

THE COMPONENTS OF OPERANT CONDITIONING

• Examples• After getting in a fight with his sister over who gets to play

with a new toy, the mother simply takes the toy away.• A teenage girl stays out for an hour past her curfew, so her

parents ground her for a week.• A third-grade boy yells at another student during class, so

his teacher takes away "good behavior" tokens that can be redeemed for prizes.

DIFFERENCE BETWEEN CLASSICAL CONDITIONING AND OPERANT CONDITIONING

• Classical Conditioning:• First described by Ivan Pavlov,

a Russian physiologist• Involves placing a neutral

signal before a reflex• Focuses on involuntary,

automatic behaviors

• Operant Conditioning:• First described by B. F. Skinner,

an American psychologist• Involves applying reinforcement

or punishment after a behavior• Focuses on strengthening or

weakening voluntary behaviors.
