EXPLANATORY STYLE AND GAMBLING - HOW PESSIMISTS RESPOND TO LOSING WAGERS

Fifty-three patrons of a harness racing track completed two measures of explanatory style prior to an afternoon's races. One measure assessed general explanatory style, using bad events taken from the Attributional Style Questionnaire, and the other measure assessed betting-specific explanatory style, using bad events specific to harness race betting. Subjects then kept a diary during the first eight races. After each race, they reported how much they had bet, whether they had won or lost, the major cause of the outcome, their confidence about winning future bets, and whether they were ruminating about past or future races. Explanatory style assessed in both ways had similar correlates. Explanatory style predicted the specific attributions made by subjects for losses. Pessimistic explanatory style (internal + stable + global attributions) predicted rumination following a lost bet, but it was unrelated to expressed confidence. Rumination after a loss was in turn associated with larger wagers on subsequent races and a tendency toward less successful wagers. These results clarify one way in which pessimistic explanatory style results in helplessness, and suggest a path by which problematic gambling may develop. © 1990.
