Superstitious behavior in humans.
Superstitious habits can pop up in typical adults, but they are rare and vanish unless sensory payoff or real contingencies take over.
01Research in Context
What this study did
The researcher sat 20 college students in front of a computer.
Points dropped into their account every 15 seconds no matter what they did.
The students could press keys, wave their hands, or just wait.
The session lasted 50 minutes while the camera recorded every move.
What they found
Only three students kept doing the same odd ritual over and over.
One always tapped the space bar twice.
Another drew little circles with his finger.
The rest showed no clear pattern even though the free points kept coming.
How this fits with other research
Barton et al. (2019) extends the idea. They show that sensory hypersensitivity can lock both autistic and typical kids into repetitive actions.
The trigger is not free points but unwanted noise, lights, or textures.
Firth et al. (2001) used the same single-case lab style with pigeons.
They found that varied responses hold up better against disruption than repeated ones.
Together the three studies say: unusual patterns can form without real contingencies, but they stay rare and fragile unless a sensory payoff steps in.
Why it matters
Do not assume every odd client habit is reinforced.
First check if it feels good to the senses or if reinforcement is truly contingent.
When you remove accidental payoff or sensory input, the quirky act often fades on its own.
Save intervention time for behaviors that keep delivering real consequences.

03Original abstract
Twenty undergraduate students were exposed to single response-independent schedules of reinforcer presentation, fixed-time or variable-time, each with values of 30 and 60 s. The reinforcer was a point on a counter accompanied by a red lamp and a brief buzzer. Three color signals were presented, without consistent relation to reinforcer or to the subjects' behavior. Three large levers were available, but the subjects were not asked to perform any particular behavior. Three of the 20 subjects developed persistent superstitious behavior. One engaged in a pattern of lever-pulling responses that consisted of long pulls after a few short pulls; the second touched many things in the experimental booth; the third showed biased responding called sensory superstition. However, most subjects did not show consistent superstitious behavior. Reinforcers can operate effectively on human behavior even in the absence of a response-reinforcer contingency and can, in some cases, shape stable superstitious patterns. However, superstitious behavior is not a consistent outcome of exposure of human subjects to response-independent reinforcer deliveries.
