Erroneous verbalizations and risk taking at video lotteries.

This study examined the effect of erroneous perceptions verbalized by a game accomplice on participants' gambling. The sample consisted of 22 men and 10 women, aged 18 and older, who did not show excessive gambling problems, but who had played video lotteries at least once during the last 6 months. The participants were randomly assigned into one of three groups, where they gambled in the presence of an accomplice who verbalized three types of perceptions: (1) the accomplice emitted erroneous thoughts about gambling, (2) the accomplice verbalized adequate thoughts about gambling, or (3) the accomplice did not speak. Results showed that players exposed to an accomplice's erroneous verbalizations took significantly more risks than players in the other two groups. Erroneous perceptions appear to be easily transmissible and have impacts on gambling behaviour. The practical and theoretical implications of these results are discussed.
