Cannot tell from your details

  • This study enrols ages 18-55. Add your age to check whether you fit.
  • This study requires right-handed participants and your profile does not say.
  • This study uses MRI or magnetic equipment and your profile does not say whether you can be scanned safely.
  • This study screens out people who are pregnant or lactating and your profile does not say.
  • The listing is ambiguous: study appears to enrol both healthy volunteers and people with PTSD or post-traumatic stress symptoms.
  • The listing is ambiguous: neurological history is mentioned but not clearly a criterion.
  • The listing is ambiguous: study lists female-specific criteria.
  • This is a filtering hint based on the wording of the listing, not medical advice. The study team makes the final call.
Your details(not set — nothing is filtered out)

Private, local-first details.

Your answers are saved in this browser. If you sign in with one of the two provisioned Google accounts, they also sync to the same private Firebase owner vault so you do not have to re-enter them on another device. There is no analytics on this page. PressingClear my details clears the profile locally and from the synced record.

What you enter is only used to sort listings into "looks like a fit", "probably not", and "cannot tell". That is areading of the wording on each listing, not a medical or official determination. Only the study team can say whether you qualify, and they will screen you themselves.

How old are you?

Nearly every listing states an age range, so this is the single most useful answer.

Are you right-handed?

Some brain-imaging studies enrol right-handed participants only.

Can you safely have an MRI scan?

Say no if you have metal in your body, an implanted device, a pacemaker, or you cannot tolerate an enclosed scanner.

Do you have a cardiovascular condition?

For example heart disease, high blood pressure, or a past cardiac event.

Are you currently pregnant?
Do you have a history of seizures or epilepsy?
Sex

A handful of studies enrol one sex only. Nothing else uses this.

Would you be willing to fast before a visit?

A few studies need you to arrive without having eaten.

Are you a Texas A&M student?

Some studies recruit through the university subject pool; a few want non-students.

Many of these postings are out of date, so the first thing to ask is whether the study is still recruiting. The draft below does that for you, and states anything from your details that the listing screens for — it will not leave that out to improve your odds.
