Understanding Pavlovian Conditioning and Its Implications

Pavlovian Conditioning

Learning process through stimulus-response associations.

Unconditioned Stimulus (US)

Stimulus that naturally triggers an unconditioned response.

Unconditioned Response (UR)

Automatic response to an unconditioned stimulus.

Conditioned Stimulus (CS)

Initially neutral stimulus that gains significance through conditioning.

Conditioned Response (CR)

Learned response to a previously neutral stimulus.

Physiological Response

Body's automatic reaction to stimuli, like drugs.

Operant Conditioning

Learning through consequences of voluntary behavior.

Involuntary Response

Automatic reaction not under conscious control.

Voluntary Response

Conscious action influenced by previous consequences.

Prediction in Conditioning

Conditioning involves anticipating important events.

Ivan Pavlov

Physiologist known for research on conditioning.

Nobel Prize in Medicine

Awarded to Pavlov for his physiological studies.

Chemotherapy Example

Chemo induces nausea, linked to food cues.

Allergic Response

Sneezing triggered by pollen as a CS.

Antabuse Treatment

Conditioned aversion to alcohol through nausea.

Autoshaping

Training where animals learn to associate cues with rewards.

Morphine Response

Pain sensitivity increases due to conditioning with morphine.

Alcohol Conditioning

Environmental cues lead to physiological responses to alcohol.

Lightfoot Study

Location affects intoxication levels during drinking.

Siegal's Heroin Study

Mortality rates differ based on drug context.

Conditioned Tolerance

Tolerance developed through environmental cues predicting drug use.

Withdrawal Effects

Physiological reactions when stopping drug intake suddenly.
