The aim of the research reported in this paper was to explore empirically whether levels of participation in horserace betting are affected by the complexity of the betting task. The study employed a systematic random sample of 1161 betting decisions made in UK offcourse betting offices during 1987. The research was conducted in a naturalistic setting where it was possible to grade complexity and to measure levels of participation. Complexity was defined in terms of both the number of alternatives in the decision-maker's choice set (number of horses in a race) and the complexity of the attributes set for each horserace (handicap vs. non-handicap races). Results indicated that bettors are not inhibited by alternative-based complexity, but may be inhibited to some extent by attribute-defined complexity.
本文所报告的研究目的是通过实证研究来探究参与赛马博彩的程度是否会受到博彩任务复杂性的影响。该研究采用了系统随机抽样的方法，选取了1987年英国场外博彩办公室做出的1161个博彩决策。这项研究是在一个自然环境中进行的，在这个环境中可以对复杂性进行分级，并衡量参与程度。复杂性是根据决策者选择集中的备选方案数量（一场比赛中的马匹数量）以及为每场赛马设定的属性复杂性（让磅赛与非让磅赛）来定义的。结果表明，投注者不会受到基于备选方案的复杂性的抑制，但可能会在一定程度上受到属性定义的复杂性的抑制。
