Source text — check our reading against the listing

Below is the compensation and duration text exactly as the university publishes it, markup and all. Everything above is derived from these two strings. If they disagree with our numbers, believe these.

Compensation, verbatim

If participants agree to take part in this research, we will pay for each visit completed = $20 for the screening visit and $100 for each study visit completed to compensate for time and effort. If all visits are completed, compensation is up to a total of $620.

How it was read:

  • amount is phrased as a ceiling ("up to"); guaranteed floor unknown
  • stated total taken from a long prose description; other amounts were ignored

Duration, verbatim

The study involves 1 screening visit lasting up to 2 hours followed by 6 study days lasting up to 7 hours that can be completed within 4 weeks.

Cannot tell from your details

  • This study enrols ages 60-80. Add your age to check whether you fit.
  • This study requires fasting and your profile does not say whether you are willing to fast.
  • 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.

Get in touch

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.
