UNIVERSITY OF CALIFORNIA, SAN DIEGO
CONSENT TO ACT AS A RESEARCH SUBJECT
Timothy Brady, Ph.D., is conducting a research study to find out more about attention, memory and vision. You have been asked to participate because you are a healthy young adult. There will be approximately 1600 participants in this study this year. The expected duration of the study is 5 years, though your participation will last only between 3 minutes and 45 minutes, with the exact expected timing listed in the HIT description.
PROCEDURES. If you agree to participate in this study by accepting this HIT and continuing in the task, the following will happen to you:
1. You will be shown displays of letters, words, or pictures, right here in your web browser.
2. You will try to perceive and remember these stimuli, and respond by pressing keys or moving and clicking the mouse in a manner that we will describe to you.
RISKS. You will be required only to continue to interact with your web browser and make responses for a short duration. Thus, no potential risks or discomforts are anticipated except for the possibility that some tasks may be slightly boring. However, there may be risks that are currently unforeseeable.
PAYMENT/REMUNERATION. In consideration of your time, you will receive payment at the rate described through the Amazon Mechanical Turk system. Compensation will range from $0.60 (for a 3 min task) up to as much as $8 (for a task that takes 45 min), with rates between $8/hr and $12/hr. The exact payment rate for this HIT is provided in the HIT description.
RIGHTS. You may call the UCSD Human Research Protection Program at 858-657-5100 to ask about your rights as a research subject or to report research-related problems.
BENEFITS. There will be no direct benefit to you from these procedures. However, the investigator may learn more about basic questions pertaining to attention, memory and vision. This knowledge may have benefits to society in fields ranging from improving education to visual design, but these benefits will be indirect.
EXPLANATION. The researcher has explained this study to you and answered your questions. If you have questions about the research or research-related problems, including any adverse events, you may reach Dr. Timothy Brady at timbrady@ucsd.edu or 858-822-4530.
VOLUNTARY NATURE OF PARTICIPATION. Participation in research is entirely voluntary. You may refuse to participate or withdraw at any time without penalty. The alternative to participation is to choose not to participate.
CONFIDENTIALITY. Research records will be kept confidential to the extent allowed by law. As with all research, there is also the possibility of loss of confidentiality. Information from participants such as yourself will be identified by a subject number, which is not associated with your identity, by the researchers, to minimize the potential loss of confidentiality.
By clicking “I agree”, you are indicating that you are at least 18 years old, have read this consent form and agree to participate in this research study. Please print a copy of this page for your records.
On each trial, you'll see four colors and need to remember their hues as accurate as possible (they are all different).
We encourage you to use visual memory (remember as if you are taking a photograph of it).
Please keep your eyes at the crosshair in the middle.
Two colors will appear breifly at 4 of 12 locations that form a ring (not at two circles on the side of the crosshair)
Please press space bar to continue.
You'll see something like this but only briefly (less than a second).
You might find it a little challenging sometime. Don't worry and just try your best.
Please press space bar to continue the demo.
Then, the colors will disappear for a short period (less than a second).
Please press space bar to continue.
Then two very similar color choices will appear on each side of the crosshair, you will have to report the correct hue at the test location (pointed by the arrow).
Please press "Z" to choose the left circle OR "M" to choose the right circle as your response.
The next trail will start after you make a response.
The sequence will always be like this. Four colors come up and disappear for a brief period, then you make a response, and repeat.
Are you ready?
Please press space bar to continue (please click accept first if you haven't).
Press 'z' for left, 'm' for right.
