Stanford Psychology Department-Researcher FAQs

1. How do I get access to the Psych 1 participant pool?
Applications are necessary for any use of the Psych 1 participant pool (including pilot studies, free-for-all studies, questionnaire studies, IRB approved studies, etc.). In order to apply for access, you need to be affiliated with the Psychology department as a faculty member, graduate student, postdoctoral fellow, visiting researcher, exchange scholar, visiting scholar, visitor, co-terminal student or honors student. The applications are due by 12PM on the first Friday of the quarter in which you’d like to use Psych 1 participants. You should turn in the application, with a copy of your IRB protocol approval letter/certification of approval and a brief debriefing statement to the Human Subject Coordinator, room 422, Jordan Hall, bldg 420 or you can email it to hscoordinator@lists.stanford.edu. Be sure to keep a copy of the IRB letter for your records, as you’ll be asked to turn it in every quarter.

The Human Subject Coordinator prioritizes the applications based on the criteria outlined by the Human Subjects Committee (graduate students and faculty are given top priority for experiment hours). You will be sent an email indicating how many experiment hours you will receive by the end of the second week of the quarter. If you are not using experiment hours, but still need access to the pool (i.e., for Q-Day, pilot studies, free-for-all studies), you will be sent instructions as well.

If you’ve never used the Psych 1 participant pool, you’ll need to request an account. Once your log in information is emailed to you log into Sona Systems at http://stanfordpsychology.sona-systems.com/ and set up your experiment. In Sona click on the “Add new study” tab at the top of the page. Select the type of study you would like to post and click “Continue” Fill out your Study Information and click on “Add this study.” To request study approval click the “My studies” tab, select your study, and click Change Study Information at the bottom of the page. Then click on “Submit a Request” next to the option to make the study visible. This will notify the administrator of your request and your study can be approved.

If you’ve already used the Psych 1 participant pool, you simply need to turn in your application. Your account will be made active again the Monday after the applications are due (the first Friday of the quarter). If you list research assistants on your application who have never had an Sona Systems account, they will have to apply for an account. If they have had an Sona Systems account in the past for the Psych 1 participant pool, just list their names on the application and they’ll be made active at the same time as you are.

For details on when you can begin running subjects, when Pre-Selection and Q-Day are, when free-for-all begins, or other important dates, see the Experiment Calendar Back to top.

2. Who can have access to the Psych 1 participant pool?
Currently, access to the Psych 1 pool is limited to people affiliated with the Psychology department as a faculty member, graduate student, postdoctoral fellow, visiting researchers, exchange scholar, visiting scholar, visitor, co-terminal student or honors student, who submitted an application at the beginning of the quarter and were approved. Only approved experimenters and the experiments they applied to run are allowed access to the pool. Back to top.

3. I am a lab manager or research staff member. Do I get participant hours?
No. Currently, access to the Psych 1 pool is limited to people affiliated with the Psychology department as a faculty member, graduate student, postdoctoral fellow, visiting researchers, exchange scholar, visiting scholar, visitor, co-terminal student or honors student. You can have access to Sona Systems to help set up and run experiments for your lab. Back to top.

4. Do I need IRB approval when I submit my application?
You may submit your application without IRB approval, so long as your protocol is under review at the IRB or up for renewal. If you will not have IRB approval by the first day to run subjects, you will not be allocated experiment hours. You can instead participate in Pre-Selection, Q-Day, and Free-for-all if your documents are approved in time. Free-for-all is when the hour allocations dissolve and experiments with approved applications can run as many Psych 1 subjects as they like. About half of the participants have not fulfilled their experiment requirement by this time and will be looking for experiments. Back to top.

5. How do I get IRB approval for a study?
If you would like to use the Psych 1 participant pool and do not yet have IRB approval, go to: http://hs.stanford.edu as soon as possible or contact Lauri Kanerva at the IRB (3-2480, Lauri.Kanerva@stanford.edu ). If you are an incoming student or new to running subjects at Stanford, please speak with your big sib, faculty advisor or faculty sponsor about participation. Back to top.

6. What if I don’t have IRB approval yet for my study?
You may submit your application without IRB approval, so long as your protocol is under review at the IRB or up for renewal. If you will not have IRB approval by the first day to run subjects, you will not be allocated experiment hours. You can instead participate in Q-Day and free-for-all if your study is approved before the deadline. Free-for-all is when the hours allocation dissolve and experiments with approved applications can run as many Psych 1 subjects as they like. About half of the participants have not fulfilled their experiment requirement by this time and will be looking for experiments. Back to top.

7. How do I get a Sona Systems user name and password?
Fill in the application. Submit this application along with your studies IRB approval letter to the Human Subjects Coordinator at hscoordinator@lists.stanford.edu by noon on the first Friday of the quarter. An account will be created for you and you will be emailed your log in information. If you are having difficulty logging in, email the Human Subject Coordinator (hscoordinator@lists.stanford.edu). Back to top.

8. What do I need to do if I only want to participate in Q-Day (if I don’t need participant hours)?
You still need to submit the application to use the Psych 1 participant pool and your IRB approval letter/certificate of approval. Your Q-Day survey must be approved by the IRB. You should also indicate in the appropriate place on the application that you do not need experiment hours, and that you’ll be participating in Q-Day. Back to top.

9. Can I run a pilot study using Psych 1 participants?
The IRB does not allow studies to be run before experimenters receive IRB protocol approval. Pilot studies are studies conducted using less than 10 people and in which the data is not used for research. They are simply to test questionnaires or data prior to an experiment. These are not applicable to anyone with access to the Psych 1 Q-Day. If you are considering a pilot study, please email the Human Subject Coordinator (hscoordinator@lists.stanford.edu) so you can receive more details. Back to top.

10. Can I pay Psych 1 participants?
No. The Psych 1 participants can only receive credit as indicated by our credit guidelines. The Psych 1 participants in the Psych 1 participant pool cannot be paid or receive gifts of any kind for their participation. If you’d like to pay participants, please visit http://psychology.stanford.edu/participate.html for details on how to sign up for the separate paid pool. Back to top.

11. As an experimenter, what am I responsible for when it comes to running Psych 1 participants?
You are responsible for running your study according to your IRB approved protocol. The department has an umbrella protocol, but ultimately the responsibility falls on the individual experimenters to stay within the guidelines of the IRB.

We do collect consent forms from all of the minors and their parents. So long as you have submitted an application and were approved, you can run minors for your study under the Psych 1 protocol.

You are responsible for debriefing the Psych 1 students that participate in your study. They are participating in these studies for credit, in order to learn more about the nature of research and the studies to which they are contributing. They are encouraged to ask questions about the study and your research methods. Please provide them with as many answers as possible. Your debriefing should include the following: 1) what is being studied, 2) your hypothesis, 3) the basic design of the experiment, 4) how their participation will be utilized and their answers evaluated in your study, and 5) any results of this study so far. If your study involves a follow-up or some special demand for secrecy, please let the participants know that they will be debriefed later on (either in person or in writing) and follow up on that promise. Back to top.

12. Am I required to debrief Psych 1 participants?
YES! You are responsible for debriefing the Psych 1 students that participate in your study. They are participating in these studies for credit, in order to learn more about the nature of research and the studies to which they are contributing. They are encouraged to ask questions about the study and your research methods. Please provide them with as many answers as possible. Your debriefing should include the following: 1) what is being studied, 2) your hypothesis, 3) the basic design of the experiment, 4) how their participation will be utilized and their answers evaluated in your study, and 5) any results of this study so far. If your study involves a follow-up or some special demand for secrecy, please let the participants know that they will be debriefed later on (either in person or in writing) and follow up on that promise.

You will be asked each quarter for a short debriefing statement (a paragraph or a few sentences) that will be available to students after the deadline to complete their experiment requirement. Back to top.

13. Can I run studies using minors in the Psych 1 participant pool?
Yes. The umbrella departmental Psych 1 protocol allows you all to use minors in your studies, so long as they and their parents sign a consent form. The consent form agrees to allow them to participate in all of the studies listed on our website. This list is compiled from the experimenter’s applications at the beginning of each quarter.

To make sure your experiment is visible to minors in Sona Systems, check your Study Information Page. Select your experiment, click Change Study Information at the bottom of the page. Back to top.

14. I didn’t turn in an application at the beginning of the quarter. Can I use the Psych 1 Pool?
No. Use of the pool is limited to experimenters that submitted an application at the beginning of the quarter. This includes participation in Q-Day and free-for-all. Back to top.

15. How are the participant hours allocated?
The Human Subject Coordinator prioritizes the applications based on the criteria outlined by the Human Subjects Committee (graduate students and faculty are given top priority for experiment hours). Simply, the number of hours that the participants will need to fulfill their requirement is divided by the number of experimenters. You will be sent an email indicating how many experiment hours you will receive by the end of the second week of the quarter. If you are not using experiment hours, but still need access to the pool (i.e., for Q-Day, pilot studies, free-for-all studies), you will be sent instructions as well. Back to top.

16. How many hours will I get?
It depends on the number of participants in the Psych 1 class. The Human Subject Coordinator prioritizes the applications based on the criteria outlined by the Human Subjects Committee (graduate students and faculty are given top priority for experiment hours). Simply, the number of hours that the participants will need to fulfill their requirement is divided by the number of experimenters. You will be sent an email indicating how many experiment hours you will receive by the end of the second week of the quarter. Back to top.

Setting Up Experiments

17. How do I sign onto Sona Systems for the first time?
Go to http://stanfordpsychology.sona-systems.com/ enter your log in information that was emailed to you. If you are having difficulty signing up, email the Human Subject Coordinator (hscoordinator@lists.stanford.edu). Back to top.

18. How do I set up my study?
See the Sona instructions manual or the how to guide . Back to top.

19. How long should my experiments be? When should I set up time slots?
We ask that you offer 30 minute (0.5), 60 minute (1.0) or 90 minute (1.5) experiments. The credit in Sona Systems will be assigned in these increments, which you can choose in your experiment settings. If your experiment takes less than 30 minutes, you still need to count that experiment as 30 minutes and credit the participant accordingly. We also ask that if your experiment runs over the allotted time, you offer the appropriate credit. For example, if your experiment is a 30 minutes study that runs 15 minutes or more over the scheduled time, award the participant 1 hour of credit. If your experiment is scheduled for 1 hour and it runs 15 minutes or more over the scheduled time, award the participant 1.5 credits. You should also deduct the appropriate amount from your allocated hours.

If you need to change the length of time for your study after you have begun running participants please contact the Human Subjects Coordinator. Your study credit allotment will need to be updated. This can be a complicated process. It is strongly recommended that you pilot your study before you begin running it in the credit pool to determine how long your time slots should be.

You should try to set up sessions between the hours of 8 AM and 5 PM. Do NOT set up time slots during Psych 1 on Monday, Wednesday, and Friday from 11:00 AM to 12:10 PM. You may consider posting time slots after class.

Back to top.

20. I can’t log into Sona Systems. Help!
There are a few reasons that Sona Systems will not allow you to log in. If you have not submitted an application to use Psych 1 participant hours (or were not listed as an RA on an application), you will not be granted access. If the deadline to run subjects has passed, you will not be granted access.

If you were listed as an RA on an application, your account will be pending until the experimenters application is approved or until they have let hscoordinator@lists.stanford.edu know that you will be working on their experiment (experiment title needed). If you were not listed on the original application, contact the experimenter with whom you are working. If are still having difficulty signing up, email the Human Subject Coordinator (hscoordinator@lists.stanford.edu).

Back to top.

21. How do I limit my study to a certain pre-selected population?
After you set up your study click on the “My Studies” tab at the top of the page. Click on the study you want to add participation restrictions on. Next to “Pre-screen restrictions” click the blue link that reads “View/Modify Restrictions.”Select the restrictions you want to make by clicking the boxes. You can select multiple criteria. Click “Set Restrictions” at the bottom of the page. Select the specific restrictions you want to screen for then click “Save Changes.”
A demographic report will be sent out periodically after the third week of the quarter. This report includes the participants’ SUID#s, email addresses and general demographic information. You can use this information to contact participants who would be a good match for your study. You can also email participants through Sona based on their responses to the demographic questions. After you log in go to the Sona click on the tab labeled “Prescreen results.”Click on the blue link labeled “Prescreen Qualification Analysis”. Select your participant criterion to send the email to individuals who meet your prescreening criteria. You can set up a authorization code in Sona Systems (in your experiment settings), and email that code to the appropriate participants, so only they can sign up for your study. Back to top.

22. How do I add my lab location to the list in Sona Systems?
Include it in your application. If you need to add a space later send a request to hscoordinator@lists.stanford.edu. Back to top.

23. Is it possible for me to get Sona Systems training?
Yes. We plan to offer Sona Systems training once a year, at the start of the Autumn quarter. If you have missed this training and would still like help, first contact your faculty advisor or lab manager. Chances are someone in your lab is using Sona Systems and can help you. If you still are unable to get help, email the Human Subject Coordinator (hscoordinator@lists.stanford.edu) and training will be set up with an experiences researcher in the department. Back to top.

24. How do I add a new researcher to my experiment?
If you listed your research assistants on the application to use Psych 1 participant pool and they have never had an Sona Systems account with the Psych 1 participant pool, the administrator will create an account for them. If they already have an Sona Systems account and were listed on your application, they will be approved automatically and their old log in information will work. You can add your RAs to your own experiment, once their Sona Systems account has been approved. Once they are active, you may highlight as many experimenters as you like in the experimenter pull-down menu (using the Ctrl or Apple key).

If you were not able to indicate your research assistants on the application and they have never had an Sona Systems account with the Psych 1 participant pool, submit a request to the Human Subject Coordinator (hscoordinator@lists.stanford.edu) via email. In the email include the full name of the RA and their email address so an account can be created for them. If they already had an Sona Systems account and just need to be made active, send the same email to The Human Subject Coordinator with their name. You can add your RAs to your own experiment, once their Sona Systems account has been approved. Once they are active, you may highlight as many experimenters as you like in the experimenter pull-down menu (using the Ctrl or Apple key)

Back to top.

25. Can my research assistant have access to Sona Systems to track sessions and make changes?

If you listed your research assistants on the application to use Psych 1 participant pool, they will be emailed log in information and can log themselves in to Sona. You can add your RAs to your own experiment, once their Sona Systems account has been approved. Once they are active, you may highlight as many experimenters as you like in the experimenter pull-down menu (using the Ctrl or Apple key).

If you were not able to indicate your research assistants on the application, email the Human Subject Coordinator (hscoordinator@lists.stanford.edu) their full name and email address and an account will be created for them. You can add your RAs to your own experiment, once their Sona Systems account has been approved. Once they are active, you may highlight as many experimenters as you like in the experimenter pull-down menu (using the Ctrl or Apple key).

NOTE: Beginning Winter 2008 all research assistants in the Psychology department will be required to attend a research assistant training session. Back to top.

26. Can I add a new experiment after I’ve been allocated hours?
Access to the Psych 1 pool is limited to experimenters who submitted an application at the beginning of the quarter and were approved. If you applied to run this experiment, and were granted access to the pool, then you can add the experiment to Sona Systems and begin running subjects, using your hours allocation. If you did not submit an application for this experiment, you are not permitted to add the experiment to Sona Systems.

The students (and their parents, if they are minors) in Psych 1 consented to participating in the studies we listed as being offered at the beginning of the quarter. This list of studies comes from the experimenter applications. This list is posted to the web the 1st day to run subjects and cannot be changed until the following quarter. Back to top.

Pre-Selection and Q-Day

27. What are Pre-Selection and Q-Day?
Pre-Selection is a way for experimenters to find out more about the participants than is asked in the demographic questions . Q-Day is a series of questionnaires that experimenters use to collect data for their research. Each of these studies requires that the participant show up for a 1 hour session, where they fill out as much of the packet as they can.

As a researcher you can choose to participate in either or both of these studies. If you would like to participate in Pre-Selection or Q-Day, you need to indicate this on the application for use of the Psych 1 participant pool. Additionally, you’ll need to turn in your Pre-Selection and/or Q-Day questionnaires to the Human Subject Coordinator (Jordan Hall, bldg 420, room 422 or to hscoordinator@lists.stanford.edu) by the appropriate date (see the Experiment Calendar) For Q-Day you may use multiple versions of your survey. If you are intending to use a few different versions of a relatively similar questionnaire, you need only turn in one version. If you intend to use completely different questionnaires, please turn in a copy of each one you’d like to include in the packet. These questionnaires should be approved by the IRB and covered by your IRB protocol.

The questionnaires must include a space for the student to write in their SUID#. The copy that is turned in to the Human Subject Coordinator must include your name, protocol # and the time it takes to complete your questionnaire. The questionnaire can take no longer than 2 minutes and can be no longer than 2 sides of one piece of paper. The Human Subject Coordinator and a few helpers will complete and time each of the questionnaires. If your questionnaire takes more than 2 minutes, you’ll be asked to make revisions.

If you turn in your questionnaire by the deadline, you may participate in Pre-Selection and/or Q-Day. To do so, you’ll be asked to attend the collation and decollation sessions (see the Experiment Calendar), bringing with you the appropriate materials. The Human Subject Coordinator will indicate what is necessary to bring to the collation and decollation sessions prior to the events. Back to top.

28. When/Why do I have to submit my pre-selection and q-day questionnaires to the Human Subject Coordinator?
You’ll need to turn in your Pre-Selection and/or Q-Day questionnaires to the Human Subject Coordinator (Jordan Hall, bldg 420, room 422 or to hscoordinator@lists.stanford.edu) by the appropriate date as indicated on the Experiment Calendar. If you are intending to use a few different versions of a relatively similar questionnaire for Q-day, you need only turn in one version. If you intend to use completely different questionnaires, please turn in a copy of each one you’d like to include in the packet. You may only use one version of your survey for Pre-selection. Your questionnaires should be approved by the IRB and covered by your IRB protocol for both Pre-selection and Q-day. Do NOT "Pilot" during these sessions.

The questionnaires must include a space for the student to write in their SUID#. The copy that is turned in to the Human Subject Coordinator must include your name, protocol # and the time it takes to complete your questionnaire. The questionnaire can take no longer than 2 minutes and can be no longer than 2 sides of one piece of paper. The Human Subject Coordinator and a few helpers will complete and time each of the questionnaires. If your questionnaire takes more than 2 minutes, you’ll be asked to make revisions.

You are asked to turn the questionnaires in ahead of time so the Human Subject Coordinator can make sure they take 2 minutes or less. The Department also needs to keep track of who will be participating in the sessions and how long the packet will be. Additionally, copies are kept of all of the questionnaires in the event the IRB needs to look through them. We are only approved to conduct Pre-selection and Q-day with surveys approved under individual researchers' protocols so it is really important that your survey and survey procedures are approved by the IRB. If you have not have your survey approved by the IRB please contact them as soon as possible to get it reviewed. Back to top.

29. How long should my Pre-Selection and/or Q-Day questionnaire be?
The questionnaire can take no longer than 2 minutes and can be no longer than 2 sides of one piece of paper. The Human Subject Coordinator and a few helpers will complete and time each of the questionnaires. If your questionnaire takes more than 2 minutes, you’ll be asked to make revisions. Back to top.

30. What do collation and decollation mean when it comes to Pre-Selection and Q-Day?
The department has a system of collating the packets for the participants that is fair and balanced. It requires the experimenters who participate to stand around a large table in the lounge and create the packets for the participants by hand. You’ll be asked to bring a certain number of copies of your questionnaires to the session. The collation sessions usually take less than one hour. Decollation is when all the experimenters who participated stand around a table and collect their questionnaires. Decollation usually takes less than 30 minutes. Detailed directions will be given at the session and email reminders will go out in the week before each session. Check the Experiment Calendar for dates and times of these sessions. Back to top.

31. How many copies will I need to bring of my Pre-Selection or Q-Day questionnaire to collation?
It depends on how many students are enrolled in Psych 1. If you have submitted an application, indicated you want to participate in Pre-Selection and/or Q-Day and have been approved to use the Psych 1 pool, you will be contacted by email regarding the number of copies necessary for the Pre-Selection or Q-Day collation. Back to top.

32. What if I cannot make it to collation or decollation, but want to include/retrieve a questionnaire?
You need to send a representative in your place to collate your questionnaire into the packet and to collect your questionnaires. At decollation no one but you or the representative you send is responsible for your questionnaires. They could wind up in the garbage, so be sure to work this out ahead of time! The person you send to decollation must know what your survey looks like and who they are standing in for. Back to top.

Assigning Credit

33. How do I assign credit to participants?
During your experiment set-up in Sona Systems, you’ll indicate how much credit your participants should receive (i.e., if you’re study is 30 minutes, they should receive 0.5 credit). Sona Systems automatically assigns this credit after 24 hours. If you need to make adjustments, please do so before those 24 hours are up, or contact the Human Subject Coordinator (hscoordinator@lists.stanford.edu) with the participant name, experiment name, adjustment needed and reason.

If your experiment runs over the scheduled time, please adjust the participant’s credit accordingly (round up to the nearest half hour). If you cancel an experiment within 12 hours, please allot credit to the participant and deduct it from your allotted hours. If a participant does not show up or cancels an appointment within 12 hours of the experiment time, please take credit away from that participant. You need not deduct this time from your allotted hours. You may choose to penalize the participants who do not show up (or who cancel within 12 hours) up to -1 credit. If you do choose to penalize a participant, please let the participant and the Human Subject Coordinator (hscoordinator@lists.stanford.edu) know why. Back to top.

34. What if a participant doesn’t show up?
If a participant notifies you via email or phone 12 or more hours before the experiment session time, they should not be penalized. Simply adjust that student’s credit to zero (if necessary) and try and reschedule. If a participant does not show up or cancels an appointment within 12 hours of the experiment time, please adjust the participant’s credit to zero. You need not deduct this time from your allotted hours. You may choose to penalize the participants who do not show up (or who cancel within 12 hours) up to -1 credit (For a 30 minute experiment, penalize -0.5). If you do choose to penalize a participant, please let the participant and the Human Subject Coordinator (hscoordinator@lists.stanford.edu) know why. Back to top.

35. What if I have to cancel an experiment?
If you need to cancel 12 hours or more before the experiment, send the participant an email and/or call them if their number is available to you. If you need to cancel an experiment within 12 hours, please allot credit to the participant and deduct it from your allotted hours. Back to top.

36. What if my experiment runs over the allotted time?
If your experiment runs over the allotted time, please round the credit up to the nearest half hour. For example, if your experiment is a 30 minutes study that runs 15 minutes or more over the scheduled time, award the participant 1 hour of credit. If your experiment is scheduled for 1 hour and it runs 15 minutes or more over the scheduled time, award the participant 1.5 credits. You should also deduct the appropriate amount from your allocated hours. Back to top.

37. How can I assign/remove negative credit or zero credit that I’ve assigned a participant in the past?
If 24 hours has passed since your session time, email the Human Subject Coordinator (hscoordinator@lists.stanford.edu) with the name of the experiment, name of the participant, credit adjustment, and reason. The credit will be adjusted as soon as possible. Back to top.

Miscellaneous

38. What do I do if participants are not signing up for my study?
First, make sure that your experiment is Visible (and not Hidden). You need to submit a request the administrator through Sona to make your study visible.

Second, check the Advanced Settings on your Study Information page. Make sure you have selected the appropriate Pre-requisites, Disqualifiers, and Course Restrictions. Also make sure you have not required an Invitation Code if this is not applicable to your study.

Third, contact the Human Subject Coordinator (hscoordinator@lists.stanford.edu) with the name of your experiment. Back to top.

39. What is the demographic report?
All of the participants are asked demographic questions when they log into Sona Systems. They cannot sign up for experiments without answering these questions. Once they’ve completed the questionnaire (usually by the third week of the quarter), the Human Subject Coordinator can pull a report with all the SUID#s, email addresses and demographic information of all the participants. You can use this information to contact participants who would be a good match for your study. You can also set up an invitation code in Sona Systems (in your experiment settings), and email that code to the appropriate participants, so only they can sign up for your study. The demographic report will be circulated several times throughout the quarter. If you need the demographic report after the third week of the quarter and have not received one, email the Human Subject Coordinator (hscoordinator@lists.stanford.edu). Back to top.

40. When can I get the demographic report?
The demographic report is not complete until all of the participants have logged into Sona Systems and completed the demographic questionnaire (to view these questions, go to: http://psychology.stanford.edu/participatepsych1.html). The participants are required to (but do not always) log into Sona Systems by the third week of the quarter. After that you’ll begin to receive the demographic report from the Human Subject Coordinator via email. Back to top.

41. I want to add a new demographic question. What should I do?
Demographic questions are edited (and sometimes added) before the start of every quarter, based on the approval of the Human Subjects Committee. If you’d like to change or add a question, please email the Human Subject Coordinator (hscoordinator@lists.stanford.edu) with your suggestion. Back to top.

42. What do I do if I run out of participant hours, but still need more time to run subjects?
You will need to wait until free-for-all to run more subjects. Check the Experiment Calendar (http://psychology.stanford.edu/participatepsych1.html) for the date of free-for-all. This is when allocations dissolve, and everyone who submitted an application and was approved can run as many Psych 1 subjects as they like. Free for all may begin earlier than listed on the calendar if students are having a difficult time finding time slots to sign up for. About half of the participants have not fulfilled their experiment requirement by this time and will be looking for experiments. Back to top.

43. What if I cannot use all of my allocated participant hours?
Email the Human Subject Coordinator (hscoordinator@lists.stanford.edu) immediately so your hours can be reallocated to researchers who can use them. Back to top.

44. What/When is free-for-all?
Check the Experiment Calendar (http://psychology.stanford.edu/participatepsych1.html) for the date of free-for-all. This is when allocations dissolve, and everyone who submitted an application and was approved can run as many Psych 1 subjects as they like. About half of the participants have not fulfilled their experiment requirement by this time and will be looking for experiments. Back to top.

45. Who can run experiments during free-for-all?
Access to the Psych 1 pool is limited to experimenters who submitted an application at the beginning of the quarter and were approved. Only those experimenters, and the experiments they applied to run, are allowed access to the pool. Back to top.

46. Who do I contact if I have suggestions for improvements to Sona Systems?
Contact the Human Subject Coordinator (hscoordinator@lists.stanford.edu). Your suggestions are welcome. Not all of them can be accommodated, but they will all be considered by the Human Subjects Committee or Sona Systems staff. Back to top.
