ABA Fundamentals

Behavioral engineering: the reduction of smoking behavior by a conditioning apparatus and procedure.

Azrin et al. (1968) · Journal of applied behavior analysis 1968
★ The Verdict

A self-locking cigarette case that grows the wait between smokes can halve a heavy smoker’s intake without punishment.

01Research in Context

01

What this study did

The team built a pocket-sized cigarette case that locked itself. After each smoke, the timer made the next cigarette unavailable for a little longer.

Heavy smokers carried the case and tried to light up as usual. The device quietly stretched the time between cigarettes without shocks or scolding.

02

What they found

Daily smoking dropped to about half a pack. The lock-out did the work; users felt almost no discomfort.

03

How this fits with other research

Leigh et al. (2015) later paid adults for clean breath tests instead of blocking puffs. Both tricks cut smoking, showing money or hardware can do the job.

Dallery et al. (2008) swapped the case for an online deposit contract. Clients risked their own $50 and got it back for abstinence. Same self-control idea, newer tech.

Azrin et al. (1968) used the same portable gadget concept to stop slouching with a beep. The gadget style is old, yet it keeps inspiring today’s apps and deposit plans.

04

Why it matters

You can tame a habit by changing the item, not the person. A simple timer on the cigarette pack gave heavy smokers an easy 50 % cut. Try the same move with snack bags, vape pens, or nail files—lock them for set minutes and let the device enforce the pause while you stay neutral.

03Original abstract

Recent findings from animal conditioning studies have revealed methods of reducing responses to a very low level with a minimum of aversive by-products. These findings were incorporated into the design of a cigarette case that automatically locked itself for a period of time after a cigarette was removed from it. The next cigarette could be taken at the end of the interval, which was signalled by distinctive stimuli. Five heavy smokers were allowed to become accustomed to using the case. Then, the duration for which the case was locked was gradually increased over a period of weeks to about 1 hr. Smoking gradually decreased to the target level of about one-half of a package of cigarettes per day. Control procedures showed that specific features of the apparatus were responsible for the reduction of smoking. The results indicated that this apparatus was sufficiently effective, convenient, and acceptable to smokers to constitute a practical procedure for reducing smoking to the level considered medically safe. The procedure may also have potential for reducing other habit-forming or addictive behaviors.
