★ The Verdict

Treat breathing as an operant and you can reinforce your way to lower anxiety.

01Research in Context

01

What this study did

Parmenter (1999) wrote a theory paper. The author asked: can we treat anxiety breathing problems with ABA tools?

The paper says breathing is an operant. It can be shaped, reinforced, and punished like any other response.

The author mixes Pavlovian and operant ideas. The goal is to re-train breathing to cut anxiety and clear brain fog.

02

What they found

The paper does not give new data. It maps a plan: use conditioning to swap fast, shallow breaths for slow, deep ones.

The claim is that once breathing changes, anxiety and cognitive errors will drop.

03

How this fits with other research

Weiss et al. (2001) extend the idea. They add animal data showing breathing can also be classically conditioned. Together the two papers cover both operant and Pavlovian paths.

Holtz et al. (2019) give real numbers. One week of repeated hyperventilation practice erased the startle spike in high-anxiety adults. The lab result backs the 1999 call for breathing retraining.

Wulfert (1994) takes the same logic to hypertension. The author says avoidance-produced shallow breathing raises blood pressure. Same mechanism, new clinical target.

04

Why it matters

You already shape behavior all day. Now see breathing as one more response you can graph and reinforce. Add a simple count: inhale 3 s, exhale 5 s. Deliver praise or tokens when the client hits the target pace. Over days the breath slows, anxiety drops, and attention sharpens. No extra gadgets needed—just your timer, data sheet, and reinforcement.

03Original abstract

The purpose of this article is to bring attention to breathing as a behavior that can be modified by means of Pavlovian and operant principles of control. With this aim in mind, this paper (a) reviews a selection of early and recent conditioning studies (Pavlovian and operant paradigms) in respiratory psychophysiology, (b) discusses the bidirectional relationship between breathing and emotion/cognition, and (c) discusses theoretical and applied implications that point to new directions for research in the laboratory and clinic. Emphasis is placed on dyspnea/suffocation fear and the acquisition of anticipatory dyspnea/suffocation fear in panic, anxiety, and stress disorders and their concomitant cognitive deficits. Discussions throughout the article focus on research relevant to theory and application, especially applications in programs of remedial breathing (breathing retraining) designed for the treatment of psychophysiological disorders (e.g., panic, anxiety, and stress) and the accompanying cognitive deficits that result from cerebral hypoxia induced by conditioned hyperventilation.
