About this study
Official title: How Motor Cortex Supports L2 Acquisition of Spoken Words, Signs, and Characters Via Perception and Production
Self-production facilitates acquisition of spoken words, signs, and characters from an unfamiliar second language. The proposed work investigates how motor cortex, a key part of the brain enabling body action, supports their acquisition via production as well as perception, providing insight into whether they are learned via mental simulation of the body actions used to produce them. It is hypothesized that activity in motor cortex will differ based on the body part used to produce lexical items (e.g., mouth vs. hands), will be greater for lexical items learned via production than observation, and will differentiate lexical items recognized successfully vs. unsuccessfully.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Self-productionBehavioural
After participants learn L2 lexical items via hearing or observing them paired with L1 translations, they are prompted to produce them themselves
| Study group | Role | What they receive |
|---|---|---|
| Self-production | Experimental | L2 lexical items self-produced at learning Receives: Behavioral: Self-production |
| Perception | Active comparator | L2 lexical items heard or observed an additional time at learning Receives: Behavioral: Self-production |
What is being measured
The primary outcome is the main question the study is designed to answer.
Functional activity in motor cortex location, 5 min, recognition
Location of Blood Oxygen Level Dependent (BOLD) signal in motor cortex at recognition
Measured: 5 minutes after learning
