In ________ conditioning, the unconditioned stimulus unconditionally elicits a reaction. For example, a bit of black pepper blow
kipiarov [429]

Answer:

The answer is: Classical Conditioning.

Explanation:

  • According to the theory of Classical Conditioning, an Unconditional Stimulus can be defined as such a stimulus that is capable of triggering a response spontaneously and naturally without the requirement of a previous learning or knowledge about the stimulus.
  • A Neutral stimulus can be defined as such a stimulus which is responsible for drawing or focusing the attention of a person to a particular event.
  • A Conditional Stimulus can be defined as such a stimulus which is generated due to the repeated integration of an Unconditional stimulus to a Neutral stimulus. The repeated integration eventually results in the generation of a conditioned response.
  • In the given example, a bit of black pepper blown into the eyes for the first time is an example of unconditional stimulus. This stimulus initiates a spontaneous or unconditional response, that is, blinking of eyes.
  • But, when this unconditional stimulus gets integrated to the neutral stimulus (irritation in the eyes draws the attention of the person) repeatedly, it can result in the generation of a Conditioned Response (blinking of eyes whenever any foreign object gets into it).
