Clarkson University Psychology Professor’s Study Featured in Science News Article on Scoring Streaks
The results of a new study by Clarkson University Psychology Professor Andreas K. Wilke and his collaborators Benjamin Scheibehenne (University of Basel, Switzerland) and Peter Todd (Indiana University, Bloomington) have been featured in an article in the February 12 issue of Science News, the award-winning biweekly national news magazine.
The feature article, "In the Zone," examines lines of research into how evolution may have trained the mind to see scoring streaks -- even where they don’t exist.
Detecting contingencies and patterns in one’s environment is an important aspect of adaptive behavior. When predicting the next outcome in a sequence of events, people often appear to expect streaky patterns, such as that sport players can develop a "hot hand," even if the sequence is actually random.
This expectation, referred to as "positive recency," can be adaptive in environments characterized by resources that are clustered across space or time (e.g., food, animals, water sources, etc.). But how strong is this disposition towards positive recency?
The results of the new study by Wilke and his collaborators suggests that people have a strong prior or default expectation that sequences of events in their environment are positively autocorrelated, even when tested in the context of a computerized gambling task in which they had to predict the outcomes of two slot machines.
The effects were strong enough to even lead subjects to prefer random sequences over alternating ones that they could have better predicted, and ultimately could have earned money with. Subjects’ prior expectations appeared difficult to overcome, even with repeated feedback and the opportunity for direct comparison between sequences of different slot machines.
