Classical Conditioning Overview

• Conditioned Stimulus (CS) and Unconditioned Stimulus (US):

  • In classical conditioning, a neutral stimulus (NS) is paired with an unconditioned stimulus (US), leading to a conditioned response (CR) when the neutral stimulus becomes a conditioned stimulus (CS).

• Example of Conditioning:

  • A rat can be conditioned by associating a sound (CS) with food (US), which eventually causes the rat to salivate upon hearing the sound alone.

Extinction in Classical Conditioning

• Definition of Extinction:

  • Extinction occurs when the CS is presented without the US over time, leading to a decrease in the conditioned response.

• Application of Extinction:

  • To extinguish a conditioned response, one may repeatedly present the CS without the US.

Taste Aversion

• Conditioned Taste Aversion:

  • This phenomenon occurs when an individual develops an aversion to a specific food that was associated with illness (even if the food is not the cause).

  • Example: If a person becomes sick after eating a particular food, they may develop a strong aversion to that food.

• Mechanism:

  • This is believed to be a survival mechanism in animals to avoid poisonous substances that previously made them ill.

Counter Conditioning Techniques

• Definition:

  • Counter conditioning involves pairing a desired stimulus with a positive experience in order to change the response to a previously aversive stimulus.

• Implementation:

  • Gradually introducing small amounts of the food associated with illness while pairing it with a pleasurable experience (e.g., a favorite drink) can help change the negative association.

  • Continuous exposure with positive reinforcement can potentially help in diminishing the aversion response.

Individual Variability in Responses

• Individual Differences:

  • The effectiveness of conditioning and counter conditioning can vary greatly between individuals, complicating the process of changing strong aversions.

  • The personal history and sensitivity to the aversion play a significant role in how successful the reconditioning may be.

Environmental Modifications

• Environmental Factors in Taste Aversion:

  • Changing the environment where the food is consumed can help disrupt the learned aversion.

  • Example: Eating pancakes in different settings (like a living room instead of a kitchen) may alter the negative associations with the food.

Utilizing Pharmacological Aids

• Medication and Appetite Stimulation:

  • Using medications or supplements that stimulate appetite or reduce nausea during treatment may help introduce aversive foods gradually.

• Miracle Berries:

  • These berries can change the taste perception, making bitter foods taste sweet, which could be beneficial in overcoming taste aversions caused by prior negative experiences.

  • Research and understanding their properties might provide new avenues for addressing conditioned taste aversions.
