Dear Colleagues,

Are cognitive control and cognitive effort the same thing?

I am confused. In the neuroscientific literature on second language learning, the neural organization of cognitive control and cognitive effort seems to overlap (e.g., the anterior cingulate, dorsolateral prefrontal cortex, inferior parietal regions). At the same time, I have come across some results that make me think that cognitive control and cognitive effort are not the same thing.

For instance, I have found fMRI studies that reported increased "cognitive effort" (and therefore more widespread fMRI activation) in less proficient speakers of a second language (e.g., Abutalebi et al. 2018). At the same time, several ERP studies have suggested more "cognitive/language control" in highly proficient second language users. For example, Fernandez et al. (2013) have shown that higher second language proficiency was associated with a greater mean N2 amplitude (greater inhibition) on an executive function test. Another example: Rossi et al (2018) concluded that individuals with high second language proficiency require more cognitive/language control for their first language, even before they speak their second language.

I will greatly appreciate your help.

With my best wishes,

Monika
