Learning a new language?

One size doesn’t fit all!

What we do at ATI Lab

ATI stands for aptitude-treatment interactions. In plain English: our lab is looking into how different people respond to different types of language instruction. What works well for one person may not suit another person.

Abilities and preferences differ between individuals. Our research aims to understand how we can best match a specific profile with specific learning and teaching materials. We want to make language learning and language instruction more successful and more enjoyable for all.

Who we are

We are an international group of researchers with expertise in applied linguistics, language learning, language teaching and language testing.

Current project: Intensive or distributed practice?

We are investigating which type of language practice works best for people with different profiles.

We use some short online Polish language lessons for complete beginners that provide either massed (intensive) practice in a single session or spaced (distributed) practice in several shorter sessions.

Which approach will work best for people with ADHD (Attention Deficit Hyperactivity Disorder) and for neurotypical people, i.e. people who do not have ADHD or are otherwise neurodiverse?
