Preregistered replication report on bilingual advantages in executive function

As promised during COM2016 the Lemma group intends to start up a large-scale, multilab preregistered study, to assess whether there is an effect (and of what size) of bilingualism on executive function. We are currently in the process of working out a proposal. If the basic idea and methodology passes peer-review, other labs can sign up to join this effort. If you already wish to express your intention to join this effort, or if you have suggestions you’d like us to take on board in developing this study, do let us know by sending an email to We are keen to include labs from all over the world.
