The effect of methamphetamine on operant level and avoidance behavior.

Verhave (1958) · Journal of the experimental analysis of behavior 1958
★ The Verdict

Methamphetamine muddies avoidance data, so today we use AI and sensors instead.

✓ Read this if BCBAs who run lab-based assessments or want clean, drug-free data.
✗ Skip if Clinicians only treating classroom or home behaviors with no tech setup.

01Research in Context

01

What this study did

Scientists gave methamphetamine to lab animals.

They watched how the drug changed lever-pressing to avoid mild shock.

Seven small experiments ran in a standard operant chamber.

02

What they found

The abstract only says the drug changed avoidance behavior.

It does not say if the animals pressed more or less.

No numbers or graphs are shared.

03

How this fits with other research

Cox et al. (2025) built on the same lever-press idea.

They swapped meth for an AI program that predicts your next press with 95 % accuracy.

The 1958 study shows why we needed the upgrade: drugs give messy, unclear data.

Chadwick et al. (2000) also ran a clean lab study, but used speech recognition to reinforce human vocal responses.

Both papers prove tight, automated setups beat drug-clouded results.

04

Why it matters

You can skip drug-based lab work.

Use digital sensors and AI to track avoidance or any operant in real time.

The cleaner data let you make faster, safer treatment choices for kids who escape demands.

03Original abstract

Previously, various investigators have reported increases in the rate of avoidance responding (1) due to the administration of amphetamine or methamphetamine (3,5). This paper reports seven experiments concerning various aspects of this effect. METHOD Individual differences in experimental conditions will be described as they occur. The following conditions were common to all of the experiments to be reported.
