The etymology of basic concepts in the experimental analysis of behavior.

The author traced where our everyday ABA words came from. He looked at old papers by Pavlov and Skinner. He showed how words like stimulus and reinforcement moved from lab to clinic.

The paper is a short history lesson, not an experiment. It lists the first uses of key terms. It shows how meanings shifted over 70 years.

Many terms kept their old spelling but gained new jobs. For example, Pavlov used stimulus for a bell that starts drool. Today we use the same word for a flash card that starts a mand.

Reinforcement once meant only food after a bar press. Now it covers praise, tokens, or iPad time. The word stayed, the range grew.

McAuley et al. (1986) said applied work feeds basic science. Lattal (2004) adds the back-story: the feed-in works because we borrow and bend old terms.

Conine et al. (2022) extend the history lens to ethics. They show that when ABA moved terms like behavior reduction into conversion therapy, harm followed. Knowing the past helps avoid repeating it.

Duker et al. (1996) and Cengher et al. (2020) both study extinction. The 1996 review says we lack a clear extinction manual. The 2020 study shows a new use: extinction can create response forms to shape. Lattal (2004) explains why the same word covers both views: the meaning simply grew.

If you know where a word came from, you use it with care. Say reinforcement to a new parent and they may hear bribe. Say stimulus and they may think electric shock. A quick line about Pavlov or Skinner can clear the air. Next time you write a plan, add a plain-English note beside each tech term. History helps you keep your language and your treatment on track.
