Deconstructing Uncertainty

How do humans make choices under uncertainty?

Project title

The construction of confidence in human decision making (HREC 1954681.1)

Introduction

This project aims to understand how confidence in human decision making is affected by the absence of immediate feedback after each choice, how people value feedback in the process of building confidence, and what is the potential association between personality traits and confidence. The project is funded by the University of Melbourne.

This project has been approved by The University of Melbourne’s Human Research Ethics Committee.

What will I be asked to do?

Should you agree to participate you will be asked to finish two decision tasks: a perceptual decision task and an economic decision task. The tasks will be clearly explained to you and you will have a chance to practice before the actual experiment. During the actual experiment, the computer program will record your choices during the task, your willingness to pay for feedback information and your subjective evaluation of your performance. After completing the two decision tasks, you will be asked to complete six questionnaires measuring different aspects of your personality.

The estimated time of commitment will be about 2 hours. Participation in this study is completely voluntary and the information collected will remain confidential. You will receive between $10 to $60 for your participation. Part of the payment will depend on your performance in the both decision tasks.

How will my confidentiality be protected?

This is an anonymous study. We will protect the confidentiality of your responses to the fullest possible extent, within the limits of the law. Only participant codes will be used in the storage of data. The data will be kept securely in the Department of Finance for a minimum of five years from the date of final publication. Your experimental data may be used in related future research conducted by members of the Department of Finance.

How will I receive feedback?

Results of the study will be available from the researchers’ websites, be presented at conferences and be published in peer-reviewed journals.

Will participation prejudice me in any way?

Please be advised that your participation in this study is completely voluntary. Should you wish to withdraw at any stage, or withdraw any unprocessed data you have supplied, you are free to do so without prejudice. If you are a student at the University of Melbourne, your grades will not be affected if you participate, decline to participate or withdraw from this project at any stage.
