How many words do you know?
An online study

Thank you for your interest in our study! Your participation will help us understand differences in vocabulary learning and executive function in monolinguals, bilinguals, and participants with and without ADD/ADHD.

In this entirely online study, you will be asked to match words with pictures, press a keyboard key in the same direction as an arrow on the screen, complete puzzles, and fill out questionnaires about yourself and your language experience.

On average, the study takes between 1h15 to 2h to complete. You will be thanked for your participation with a 20$ gift card (or 2 participant pool credits for Concordia University Psychology Department students).

To be eligible, YOU:

  • Must be either:

    • monolingual (speaking only English or French), or

    • bilingual (speaking English & French; Note: we are now only looking for bilinguals with ADD/ADHD)

  • Must have NO or LOW knowledge of any language other than English & French (speaking & understanding)

  • Must live in Canada

  • Must be between 18 and 34 years of age

  • Must be attending University, College, or CÉGEP, or have previously completed at least 2 years

  • May have Attention-Deficit/Hyperactivity Disorder (ADD or ADHD), or not

    • If applicable and you feel comfortable doing so, we ask that you not take your ADD/ADHD medication on the day of the study until after the study is completed. You will be reminded to take your medication at the end of the experiment.

    • You may also start the study an hour or two before the time at which you would normally take your medication, and take it at the usual time

  • Must not have any conditions which may affect your eyesight, hearing, language, or cognitive functioning
