Explanation:
It is an example of superstitious behavior that is resulting from accidental reinforcement. The accidental reinforcer occurs after an act that may unintentionally strengthen the likelihood of the occurrence of that act. Superstitious behavior is often the result of accidental reinforcement

</u>
A golfer may be lean as nears the hole. Such learning followed the past by the ball going into the hole (reinforcer) so even though leaning has no causal effects on whether the ball goes in, the accidental contingent relationship between leaning and ball being holed leads to reinforcement of leaning also called adventitious reinforcer.
