WIND AS AN AVERSIVE STIMULUS.

Researchers tested whether wind could work like shock in avoidance training. They used two monkeys in a lab cage. A fan blew wind at 10 or 20 mph during daily sessions.

The animals could press a lever to stop the wind for 30 seconds. No food or water rewards were given. The room stayed at normal temperature.

Both monkeys quickly learned to press the lever as soon as the fan started. They kept pressing and almost never felt the full 30-second wind blast.

The behavior stayed strong across many days. Wind speed did not matter; 10 mph worked as well as 20 mph.

BAER (1960) showed preschool kids will avoid when toys are taken away. The new study shows monkeys avoid when wind hits their fur. Both prove avoidance can be built with very different aversive events.

Edwards et al. (1970) used electric shock with pigeons and found warning lights change the pattern of avoidance. Here, no warning light was used; the wind itself was the signal. The monkey data fit the rule: clear signals make avoidance steady.

Zeiler (1968) taught rats to hold and release a bar to avoid shock. The monkeys only had to press once to stop wind. Simpler response, same result—avoidance learning holds across species and tasks.

You now know wind can act like shock in lab training. If you run animal studies, wind gives a cheap, safe aversive stimulus that needs no shock equipment. For human work, remember that everyday sensations like a strong fan can become signals for escape. Watch for accidental avoidance loops in classrooms or clinics where kids might leave or protest when HVAC drafts hit them.
