Response-induced reversals of preference in gambling: An extended replication in Las Vegas.

Abstract

Extends previous studies (which used undergraduates in a laboratory setting) of the effects of response mode on information-processing strategies used in gambling decisions in a Las Vegas casino using a professional dealer as E and 44 casino patrons as Ss. As in the laboratory, the casino patrons used different strategies when choosing among pairs of bets than when attaching monetary values to single bets. This behavior led to reversals of preference as a function of response mode. The reversals were found for bets with negative as well as positive expected value. Results suggest a bias due to cue-response compatibility that may have implications for information processing in a variety of decision-making situations.
