MACHINE

The mind is a product of a physical machine, the brain.

In animals, fear conditioning such as Little Albert experienced is the result of changes in a brain region called the amygdala. People with damage to the amygdala don’t seem to be afraid of anything, so it would be impossible to induce fear conditioning in them.

What occurs when a strong conditioned stimulus is paired with a neutral stimulus?

UNCONSCIOUS

We are consciously aware of only a small part of our mental activity.

People subjected to classical conditioning report that they do not consciously produce the conditioned response; it seems to happen on its own, in a reflexive fashion. Little Albert’s fearful responses certainly appear reflexive. If Albert Barger was indeed Little Albert, and if his dislike of dogs was a result of Watson’s manipulations, he was unaware of the connection.

What occurs when a strong conditioned stimulus is paired with a neutral stimulus?

SOCIAL

We constantly modify our behavior, beliefs, and attitudes according to what we perceive about the people around us.

Whichever child was the true Little Albert, he was available for Watson’s study because his mother, pregnant out of wedlock, had few options to support them. This was the result of social attitudes at the time, which heaped shame on unwed mothers. Was Watson more willing to conduct his experiment on a child in such circumstances than a child of middle-class parents?

What occurs when a strong conditioned stimulus is paired with a neutral stimulus?

EXPERIENCE

Our experiences physically alter the structure and function of the brain.

Whatever Little Albert’s true name, he became terrified of many furry objects as a result of experiencing the pairing of such stimuli with loud, startling sounds. Indeed, all instances of learning result from experience. It is possible that Albert Barger’s lifelong dislike of dogs was a result of his experiences as an infant.

Critical Thinking Exercise

�    What is the most important thing you have learned outside of a classroom?� Why?

�    Any relatively permanent _____________ in behavior brought about by experience.

�  Classical Conditioning

�  Operant Conditioning

�  Cognitive Learning

�  Observational Learning

Classical Conditioning

�    Learning to make a ___________ response to a stimulus other than the original, natural stimulus that normally produces the reflex.

Ivan Pavlov

�    Russian physiologist (person who studies the workings of the body) who discovered __________________ through his work on digestion in dogs.

Pavlov�s Observation (1926)

�    Studied digestion in dogs

�  Presented meat powder and measured salivation

�  Dogs started salivating ____________ food was presented

�  Why?

 

Pavlov�s Experiment: Phase 1

�    Food (US): salivation (UR )

�  Reflexive response

�    Tone: nothing

Pavlov�s Experiment: Phase 2

�    CS is repeatedly paired with the US

�  A tone is sounded before the food is presented

�  Acquisition

Pavlov�s Experiment: Phase 3

�    Eventually, the CS elicits a new CR

�  Classical conditioning is complete when hearing the tone by itself causes salivation

Classical Conditioning Concepts

�    Unconditioned stimulus (UCS) - a _______________________ stimulus that leads to an involuntary response.

�  Unconditioned means �______________� or �naturally occurring.�

�    Unconditioned response (UCR) - an __________________ response to a naturally occurring or _______________ stimulus.

�    Conditioned stimulus (CS) - stimulus that becomes able to produce a learned reflex response by _________________________ the original unconditioned stimulus.

�    Conditioned response (CR) - learned ________________ response to a conditioned stimulus.

�  The CR behavior is always the _________ behavior as the UR.� What distinguishes them is what they occur _____________ to (US vs. CS).

Classical Conditioning Concepts

�    Stimulus generalization - the tendency to respond to a stimulus that is only _________________ to the original conditioned stimulus with the conditioned response.

�    Stimulus discrimination - the tendency to stop making a _____________ response to a stimulus that is _____________ to the original conditioned stimulus because the similar stimulus is never paired with the unconditioned stimulus.

�    Extinction - the ________________ or weakening of a learned response following the removal or absence of the unconditioned stimulus (in classical conditioning) or the removal of a reinforcer (in operant conditioning).

�    Spontaneous recovery � the _________________ of a learned response after extinction has occurred.

�  Learning is a relatively permanent change in behavior.

�    Higher-order conditioning - occurs when a strong conditioned stimulus is paired with a neutral stimulus, causing the neutral stimulus to become a _______________ conditioned stimulus.

 

Conditioned Emotional Response

�    Conditioned emotional response (CER) - emotional response that has become _____________________________ to occur to learned stimuli, such as a fear of dogs or the emotional reaction that occurs when seeing an attractive person.

The Case of �Little Albert�

�    �Little Albert� was conditioned to fear a _________________ and other similar stimuli (Watson & Rayner, 1920)

Other Conditioned Responses

�    Vicarious conditioning - classical conditioning of a reflex response or emotion by watching the ______________ of another person (Bandura & Rosenthal, 1966).

�    Conditioned taste aversion - development of a ___________________ or aversive response to a particular taste because that taste was followed by a nausea reaction, occurring after only one association (Garcia & Koelling, 1966).

When a neutral stimulus is paired with a conditioned response?

Classical conditioning happens when a neutral stimulus is paired with an UCS repeatedly to create associative learning. The previously neutral stimulus becomes a conditioned stimulus (CS) and can trigger the same response as the UCS. So initially, the neutral stimulus does not affect a specific behavior.

What is it called when a neutral stimulus becomes a conditioned stimulus?

Pavlov had identified a fundamental associative learning process called classical conditioning. Classical conditioning refers to learning that occurs when a neutral stimulus (e.g., a tone) becomes associated with a stimulus (e.g., food) that naturally produces a behaviour.

What happens when a conditioned stimulus is paired with an unconditioned stimulus?

A conditioned stimulus is a neutral cue or event that produces an involuntary response after repeatedly being paired with an unconditioned stimulus that naturally elicits that behavior. This term originated in a learning process called classical conditioning.

What happens when you pair a neutral stimulus with a conditioned stimulus that produces a conditioned reflex?

Known as higher-order conditioning or second-order conditioning, this process causes a new neutral stimulus to pair with an existing conditioned stimulus. As a result, the newly-made conditioned stimulus can elicit the same response as the original conditioned stimulus (see example #3).
