Respondent and Operant Conditioning

Key Takeaways

  • Respondent behavior is elicited by antecedent stimuli through unconditioned or conditioned stimulus-response relations.
  • Operant behavior is selected by consequences and is analyzed through antecedent-behavior-consequence relations.
  • The same observable topography can be part of different processes depending on the controlling relation.
  • Exam questions often require identifying whether a stimulus elicits a response or a consequence changes future behavior.

Respondent Relations

Respondent behavior is elicited by antecedent stimuli. Some respondent relations are unconditioned, such as salivation to food or a startle response to a loud sound. Others are conditioned when a neutral stimulus is paired with an unconditioned or already conditioned stimulus until it elicits a response.

In respondent conditioning, the critical relation is stimulus-stimulus pairing. If a clinic room is repeatedly paired with painful dental work and later the room alone elicits crying, the room has become a conditioned stimulus. The crying is not selected by the crying's consequence in that analysis.

Operant Relations

Operant behavior is selected by its consequences. The basic exam unit is the three-term contingency: antecedent, behavior, consequence. An antecedent sets the occasion for behavior because a history of reinforcement or punishment has occurred in its presence.

A response can look emotional and still be analyzed operantly if consequences maintain it. Crying that reliably produces escape from math tasks may be an operant response. Crying elicited by a sudden painful stimulus is better analyzed as respondent. The label depends on the functional relation, not the topography.

Many applied scenarios include both processes. A child may flinch when a dentist's drill sounds and also protest to delay the appointment. Identify the relation the question asks about, then select the principle that fits that relation.
