Module 9 - Classical Conditioning

Learning

Is a relatively enduring or permanent change in behavior or knowledge that results from previous experience with certain stimuli and responses

Behavior

Includes any observable response (fainting, salivating, vomiting)

3 kinds of learning

Classical conditioning
Operant conditioning
Cognitive learning

Classical conditioning

Is a kind of learning in which a neutral stimulus acquires the ability to produce a response that was originally produced by a different stimulus

Law of effect

Says that if some random actions are followed by a pleasurable consequence or reward, such actions are strengthened and will likely occur in the future.

Operant conditioning

Refers to a kind of learning in which the consequences that follow some behavior increase or decrease the likelihood of that behavior's occurrence in the future

Cognitive learning

Is a kind of learning that involves mental processes, such as attention and memory
- may be learned through observation or imitation
May not involve any external rewards or require the person to perform any observable behaviors

Neutral stimulus

Is some stimulus that causes a sensory response, such as being seen, heard, or smelled, but does not produce the reflex being tested

Unconditioned stimulus or UCS

Some stimulus that triggers or elicits a physiological reflex, such as salivation or eye blink

Unconditioned response or UCR

Is an unlearned, innate, involuntary physioogical reflex that is elicited by the unconditioned stimulus

Conditioned stimulus or CS

Is a formerly neutral stimulus that has acquired the ability to elicit a response that was previously elicited by the unconditioned stimulus

Conditioned response or CR

Which is elicited by the conditioned stimulus, is similar to, but not identical in size or amount to, the unconditioned response

Generalization

Is the tendency for a stimulus that is similar to the original conditioned stimulus to elicit to a resonse that is similar to the conditioned response
- usually the more similar the new stimulus is to the original conditioned stimulus, the larger will be the conditioned response

Discrimination

Occurs during classical conditioning when an organism learns to make a particular response to some stimuli but not to others

Extinction

Refers to a procedure in which a conditioned stimulus is repeatedly presented without the unconditioned stimulus and, as result, the conditioned stimulus tends to no longer elicit the conditioned response

Spontaneous recovery

Is the tendency for the conditioned response to reappear after being extinguished even though there have been no further conditioning trials

Adaptive value

Frees to the usefulness of certain abilities or traits that have evolved in animals and humans and tend to increase their chance of survival, such as finding food, acquiring mates, and avoiding pain and injury

Taste-aversion learning

Refers to associating a particular sensory cue (smell, taste, sound, sight) with getting sick and thereafter avoiding that particular sensory cue in the future

Preparedness

Refers to the phenomenon that animals and humans are biologically prepared to associate some combinations of conditioned and unconditioned stimuli more easily than others

Conditioned emotional response

Refers to feeling some positive or negative emotion, such as happiness, fear, or anxiety, when experiencing a stimulus that initially accompanied a pleasant or painful event

Stimulus substitution

Means that a neural bond or association forms in the brain between the neutral stimulus (tone) and unconditioned stimulus (food)
- after repeated trials, the neutral stimulus becomes the conditioned stimulus (food)
- thereafter, the conditioned stimulus (tone) elicits a conditioned response (salivation) that is similar to that of the unconditioned stimulus

Contiguity theory

Says that classical conditioning occurs because 2 stimuli (neutral stimulus and unconditioned stimulus) are paired close together in time (are contiguous)
- as a result of this contiguous pairing, the neutral stimulus becomes the conditioned stimulus, which elicits the conditioned response

Cognitive perspective

Says that an organism learns a predictable relationship between 2 stimuli such that the occurrence of one stimulus (neutral stimulus) predicts the occurrence of another (unconditioned stimulus)
- in other words, classical conditioning occurs because the organism learns what to expect

Anticipatory nausea

Refers to feelings of nausea that are elicit by stimuli associated with nausea-inducing chemotherapy treatments, patients experience nausea after treatment but also before or in anticipation of their treatment
- researches believe that conditioned nausea occurs through classical conditioning

Systematic desensitization

Is a procedure based on classical conditioning, in which a person imagines or visualizes fearful or anxiety-evoking stimuli and then immediately uses deep relaxation to ovecome the anxiety
- a form of counterconditioning because it replaces, or counters, fear and anxiety with relaxation
