BACKGROUND

Second language (L2) oral comprehension is a demanding cognitive process involving a heavy cognitive load (Roussel et al., 2021). Despite extensive research in this field, the precise mechanisms of L2 oral reception remain insufficiently described.

The COraIL project (PhD 2022-2025, LiDiLEM-GIN, IRGA222 funding) aims to fill this gap by adopting an interdisciplinary approach combining behavioral and neurophysiological data.

The protocol is deployed in two phases:

1. Behavioral phase (2024, ongoing) :
   • Recording electrodermal responses (EDR) and heart rate variability (HRV) during oral comprehension tasks to identify cognitive and emotional obstacles.
   • Using the think-aloud protocol with a digital tool enabling learners to annotate problematic sound segments.
   • Complementary assessment of working memory as a factor influencing oral comprehension.
2. fMRI phase (2025) :
   • Observing brain activations and connectivity within the language, attentional, and cognitive networks (working memory, cognitive performance) during L1 and L2 oral comprehension tasks.
   • Comparing profiles of L2 participants at elementary (A2) and advanced (B2) levels.

This study represents a first neuroimaging collaboration between the LiDiLEM laboratory and the GIN, with the expertise of Chantal Delon-Martin (GIN) and the support of a research engineer from the LPNC.
