Classical conditioning

Experience can turn an ordinary cue into a signal that prepares an organism for what follows.

Definition

Classical conditioning is learning a relationship between events so that a cue comes to elicit a response through its association with another stimulus.

How to understand it

Begin by asking what the learner encounters, rather than what action earns a result. The crucial relationship connects a signal with a meaningful event. Identifying the cue, the event and the measured response makes the explanation testable instead of treating every familiar reaction as conditioning.

The pairing of events is a starting point, not a complete explanation. A cue that adds no useful information may acquire little control over responding. This predictive perspective helps distinguish learning about the environment from simple exposure to two things happening near each other.

A signal before a puff of air

Teaching scenario

In an imagined laboratory exercise, a small blue light reliably appears just before a harmless puff of air near a participant’s eye. At first the puff produces blinking and the light does not. Later, blinking begins when the light appears. The light is the learned signal; blinking to the puff does not itself establish learning. A comparison condition in which the events are unrelated would help evaluate the explanation.

Constructed for learning. This scenario is not a report of an empirical finding or a diagnosis.

Common confusion: Operant conditioning

Classical conditioning concerns predictive relationships between stimuli; operant conditioning concerns relationships between actions and their consequences.

Compare classical and operant conditioning

Limits of the concept

  • A conditioned response need not duplicate every feature of the original response.
  • Co-occurrence alone does not establish that a useful predictive association was learned.
