Adult gamblers completed a task that assessed !preference among eight horses during a computerized pari-mutuel horse racing game. During Experiment 1, assessments of bet allocation were conducted before and after temporal and visual discrimination !training procedures where 3 three-member stimulus classes were established. Experiment 2 controlled for participant reinforcement histories by blocking the results of each horse race. Results indicated that some participants tended increase responding toward specific horses that shared similar formal properties to those stimuli used in visual discrimination training even !though such features !had no !bearing !on !race !!outcomes.
