We conducted pre-registered replications of 15 effects in the field of judgment and decision making (JDM). We aimed to test the generalizability of different classical and modern JDM effects, including, among others: less-is-better, anchoring, and framing to different languages, cultures, or current situations (COVID-19 pandemic). Replicated studies were selected and conducted by undergraduate psychology students enrolled in a decision-making course. Two hundred and two adult volunteers completed an online battery of replicated studies. With a classical significance criterion (p < .05), seven effects were successfully replicated (47%), five partially replicated (33%), and three did not replicate (20%). Even though research materials differed from the originals in several ways, the replication rate in our project is slightly above earlier reported findings in similar replication projects.

Undergraduate Psychology

The preregistration of research plans and hypotheses may prevent publication bias and questionable research practices. We incorporated a modified version of the preregistration process into an undergraduate capstone research course. Students completed a standard preregistration form during the planning stages of their research projects as well as surveys about their knowledge of preregistration. Based on survey results, our senior-level psychology students lacked knowledge of importance of the preregistration movement in the sciences but could anticipate some of its benefits. Our review of the completed preregistration assignment suggested that students struggle with data analysis decision-making but generally perceive preregistration as a helpful planning tool. We discuss the value of a preregistration assignment for generating discussions of research practice and ethics.

Person Game

This study investigated decision making in internally and externally motivated persons as they interacted in a competitive game of skill. Subjects were 36 internally and 36 externally scoring graduate and undergraduate psychology students. All possible pairings of internal and external subjects were involved in a competitive two-person game. The game of skill required participants to bid against each other to purchase tokens which were auctioned. The results indicated that internal subjects made decisions reflecting a greater expenditure of resources and time than external subjects.
