Conditioned Response (CR)

A Conditioned Response (CR) refers to an automatic response or behavior that is triggered in an organism as a result of a specific stimulus that has been repeatedly paired with an unconditioned stimulus (US).

Overview

A CR is acquired through a process known as classical conditioning, where an initially neutral stimulus, called the conditioned stimulus (CS), is paired with an unconditioned stimulus (US) that naturally evokes a response, known as the unconditioned response (UR). Over time, when the CS is presented alone, the individual begins to exhibit the conditioned response (CR), which is typically similar or related to the UR.

Characteristics of a Conditioned Response

Several characteristics define a conditioned response:

  1. Learning-based: A CR is learned by association with the CS and the US.
  2. Acquired: The response is not innate but is acquired through repeated pairing.
  3. Specificity: The CR is specific to the conditioned stimulus and may not be generalized to other stimuli.
  4. Similarity to UR: The CR often resembles or is related to the unconditioned response (UR) in some way.
  5. Subject to Extinction: If the CS is repeatedly presented without the US, the CR may weaken or disappear over time.
  6. Recovery: After extinction, if the CS is reintroduced after a period of time, the CR may reappear temporarily.
  7. Generalization: The CR may be elicited by stimuli that are similar but not identical to the conditioned stimulus (CS).

Examples of Conditioned Responses

Some common examples of conditioned responses include:

  • A dog salivating (CR) at the sound of a bell (CS) after being repeatedly paired with the presentation of food (US).
  • Feeling anxious (CR) when entering a hospital (CS) due to past experiences of medical procedures (US).
  • Flinching (CR) at the sound of a loud noise (CS) due to previous associations with an aversive event (US).

Conditioned responses play a fundamental role in learning and behavior and are often used in various therapeutic techniques and behavioral interventions.
