Readings. Available online on Carmen. Description: This course will consist of an examination of recent developments in judgment and decision making research. The course will emphasize the examination of models that are descriptive rather than predictive or normative. That is, there will be an emphasis on models and recent empirical studies that attempt to explain cognitive processes associated with likelihood judgment and decision making under conditions of risk, uncertainty, or ambiguity. Although the goal of the course is not necessarily to teach you to become a better decision maker, we will spend some time discussing decision analysis techniques as well. What you will learn will have significant practical as well as interesting theoretical value. As we discuss current research topics we will periodically invite Aexpert@ decision makers in a number of different fields to either come and talk informally with us or to show us their decision making environment. We will try to answer three questions as we talk about decision making: 1. How do people synthesize information and make decisions? 2. How good are peoples' decisions and cognitions that underlie them? 3. How can peoples' decision behavior be improved? Prerequisites: The course is designed for undergraduates and nonpsychology graduate students. Some exposure to other content areas in psychology is useful but is not necessary. Neither the lecture/discussions nor the text will emphasize mathematical formalisms in J/DM research, but some mathematical models will be examined. Thus, although an extensive background in mathematics and/or statistics will not be required, students need to meet the statistics prerequisite. Evaluation: There will be two inclass exams (30% each). Each student will be expected to EITHER (1) write a final research paper (approximately 10 pages) on some topic of interest in the field of decision making OR (2) give a 10 minute Powerpoint class presentation on a research topic of interest. The paper or talk (20%) may be based on either a literature review of a specific J/DM topic or a short empirical study of your own. Homework and class participation will account for the remaining 20%. Two or three class periods will be set aside at the end of the quarter for students who wish to give a presentation. Order of presentation will be determined by a random drawing. Attendance at these presentations is MANDATORY. Some Important Dates: Friday Monday Wednesday June 29 Onehalf page summary of paper or presentation topic due. Students must commit to doing either a paper or presentation on this date. July 09 One page summary of paper topic due with title and references. July 18 Final paper due for those doing paper option Powerpoint file for those doing a presentation This publication/material is available in alternative formats upon request. Please contact the instructor, Thomas Nygren (2922935) in the Department of Psychology. Students with disabilities are responsible for making their needs known to the instructor, and for seeking available assistance in a timely manner. Academic Misconduct: All students at the Ohio State University are bound by the Code of Student Conduct (see http://oaa.ohiostate.edu/coam/code.html). Violations of the code in this class will be dealt with according to the procedures detailed in that code. Specifically, any alleged cases of misconduct will be referred to the Committee on Academic Misconduct.

Social Influences. There will be one major writing or presentation assignment for this course. Possible topics are listed in the first packet of notes of your Carmen web notes. You will note that there are many possible topics listed to choose from. THESE ARE ONLY SUGGESTED TOPICS YOU MAY CHOOSE ANY OTHER TOPIC IN J/DM OF INTEREST TO YOU. Don't feel as though you must choose one of these. New topics in judgment and decision making are always welcome. Paper Infornation: For those choosing the paper option, the paper can be of one of the two forms described below. In either case it should be: 1. A minimum of 8 typewritten or computergenerated (double spaced) pages including references, tables, figures, etc., but not including title and abstract 2. Written in APA format with a title page, a short 100 word or less abstract, the body of the paper, a reference list, and any tables or figures, Literature Review One possibility is that the paper takes the form of a review of literature related to some area of decision making that interests you. It could take the form of an historical development of a body of literature in which you summarize work as it has progressed over the last 10, 20, or even 30 or more years. It could also be a review of only very recent work from the 1980's and 1990's. Finally, it could be a critical review of the work of just a single researcher (e.g., Wallsten) or a pair of researchers (Kahneman and Tversky). If one of these forms is of interest to you, you might want to look at recent issues of Psychological Review or Psychological Bulletin to see examples of review type articles. Empirical Study A second possibility is to do a small decision making study. The study would by necessity have to be somewhat simple (e.g., only two groups or treatment conditions). Data analyses also would not need or have to be very extensive. That is, simple correlations, ttests, ANOVAs, etc. would probably be sufficient. You could get your subjects from friends and associates or by using volunteers in the class. You could collect your data in lab if it did not require much time (say 15 minutes). Some examples might be to look at the effect of some variable on risktaking or lossaversion, personality correlates of decision making, age differences, gambling experience, and gender differences. Other examples include looking at such things as the effects of framing, presentation modes, response modes (numerical vs. verbal probabilities), time constraints, and ambiguous or incomplete information on decision making. If you were to do this kind of paper I would allow two people to work together on the project. Data collection and analysis could be done jointly. Each person would, however, be expected to write his or her own paper independently. Presentation Infornation: For those choosing the presentation option, the presentation can also be of one of the two forms described above either a literature review or a description of an empirical study of your own. In either case it should be: 1. presented and submitted as a Microsoft Powerpoint file. 2. be an approximately 1012 minute class presentation on the topic of interest. Examples of Powerpoint presentations from a previous class will be available shortly on the website. ...
