The task of selecting the best dental applicants out of an extremely competitive applicant pool is a problem faced annually by dental faculties. This study examined the validity of both cognitive and noncognitive factors used for selection to Canadian dental schools. Interest in personality measurement and the prediction offered by personality measures has escalated and may be applied to the selection of dental candidates. Therefore, the study also assessed whether the addition of a personality measure would increase the validity of predicting performance beyond that achieved by an interview and the Dental Aptitude Test. Results suggest that an interview may be useful in identifying specific behavioral characteristics deemed important for success in dental training. Consistent with previous research, results show that the Dental Aptitude Test is a good predictor of preclinical academic success, with prediction declining when clinical components of the program are introduced into the criterion. Results from the personality measure indicated that Openness to Experience was significantly related to aspects of clinical education, although, contrary to expectations, this relationship was negative. A facet of Openness, Ideas, together with Positive Emotions, a facet of Extroversion, improved prediction of performance in clinical studies beyond that provided by the Dental Aptitude Test and the Interview. Implications of the findings are discussed, and recommendations regarding the admission process to Canadian dental programs are offered.Ms.

I present an experiment on non-binding goals and motivational effects. Consistent with results from psychology, I find that goals increase output. This is due to improved speed and accuracy. Men are more responsive to goals than women.

We examine the motivational effects of setting both assigned and personal nonbinding goals on a real effort laboratory experiment. In order to derive conjectures for our experiment, we develop a model with goal-dependent preferences. In line with previous studies, we find that goal setting leads to a higher performance. We also find that goal-setting is most effective if subjects were able to achieve previous goals. Therefore, in goal setting, "success breeds success". In particular, we observe that when subjects are initially allowed to attain assigned goals, they are better at self-motivating in the future when performing under personal goals.

Theories of trust distinguish general trust in situations of social uncertainty from assurance-based trust in committed, long-term relationships. This study investigates European-Japanese differences using the Centipede game, in which two players choose between cooperation and defection. The game models repeated reciprocal interactions, necessitating assurance-based trust to sustain cooperation. We included game conditions offering players the option of purchasing commitment-enhancing tools to increase social certainty. Japanese participants were more cooperative than Europeans, confirming higher assurance-based trust, and also purchased more commitment-enhancing tools, demonstrating their preferences for social certainty. Purchase of commitment-enhancing tools improved cooperativeness in both groups. However, if co-players refused tool purchase, the Japanese appeared to interpret this as non-cooperative intent and cooperativeness in the respective games decreased.
