PRINCIPAL INVESTIGATOR: Nathaniel Daw, Ph.D.
PRINCIPAL INVESTIGATOR’S DEPARTMENT: Psychology and the Princeton Neuroscience Institute

You are being invited to take part in a research study. Before you decide to participate in this study, it is important that you understand why the research is being done and what it will involve. Please take the time to read the following information carefully. Please contact the researcher if there is anything that is not clear or if you need more information.

Purpose of the research:

With this research we hope to explore the following objectives related to human learning and decision-making:

1. Understanding how humans learn about the structure of their environment and from feedback about rewards.
2. Understanding how humans draw on this knowledge to make decisions in the environment.

Study Procedures:

In this experiment, you'll be asked to make decisions or responses using button-presses or mouse-clicks. At the conclusion of the experiment, you will receive monetary compensation determined in part by the decisions you make during the task.

Your total expected time commitment for this study is: 45 minutes.

Benefits and risks:

You will not receive any direct benefit from your participating other than the monetary payment you will receive for participation and the possible enjoyable or rewarding aspects of participating in research.

Confidentiality:

The research team will make every effort to protect your confidentiality, as required by law. Personally identifying data will remain strictly confidential. Immediately following data collection, your age, profession, ethnic classification, and any other personally identifying information, will be separated from the rest of the obtained data and replaced by a coded designation. The personally identifying information and its mapping to code numbers will be stored in a locked cabinet in the investigator's laboratory in the Princeton Neuroscience Institute, or digitally on secure, encrypted, password-protected computers also located at the PNI. Consent forms will be stored, separately, in the same manner. We will not include any information that will make it possible to identify you in any report we might publish.

Compensation:

For this study, which is estimated to take 45 minutes, you will be compensated $8 for your participation plus an additional payment of up to $8 based on the decisions you make during the experiment.
