The effect of embedded bonus rounds on slot machine preference

Twenty‐three university students completed a simulated slot machine task involving the concurrent presentation of two slot machines that were varied both in win density and the inclusion of a bonus round feature to evaluate the effect of embedded bonus rounds on participant response allocation. The results suggest that participants allocated a greater percentage of responses to machines with embedded bonus rounds across both dense (Bonus: M = 68.4, SD = 19.2; No Bonus: M = 51.2; 9.6) and lean (Bonus: M = 48.8, SD = 9.6; No Bonus: M = 31.6, SD = 19.2) reinforcement schedules, in which the overall reinforcement rate across all machines was held constant.     

The name game: acceptability,bonus information and group size

Our previous research demonstrated the effectiveness of the name game when learning the names of group members. In three experiments we conclude our study of the name game by demonstrating that it is very acceptable to participants and successful with larger groups. Experiment 1 compared the simple and elaborate name games. In the latter, participants learned a word provided by each person in addition to their full name. This ‘bonus’ information was very well learned without detriment to the name learning. Participants rated both versions of the name game as a good use of time and worth playing again although the elaborate name game was rated as more fun. Experiments 2 and 3 used the name game with groups of around 25, finding very good recall of full names. The role of retrieval in the effectiveness of the name game was again demonstrated to be essential. Copyright © 2004 John Wiley & Sons, Ltd.     

The effects of bonus contingencies in a classwide token program on math accuracy with middle-school students with behavioral disorders

The effects of bonus points contingent on 80% accuracy in math with four middle-school special education students with behavior disorders were examined. A multiple-baseline design across students was used to evaluate the effects of bonus points. The overall results indicated that higher accuracy was found for math assignments during the bonus points condition than during baseline. This overall outcome was replicated for each subject in the study. The benefits of implementing a bonus contingency within an ongoing classroom token economy with middle-school students with behavior disorders are discussed. © 1998 John Wiley & Sons, Ltd.     

In the Beginning

In this paper, a survey is made of some of the contributionsto the interpretation of Hartle and Hawking's theory of thewave function of the universe and its beginning. It is arguedthat there are considerable difficulties with the interpretationof the theory, but that there is at least one interpretationhitherto not found in the literature which survives existingphilosophical objections.
