Introduction: Humans mainly utilize visual and auditory information as a cue to infer others' emotions.

Article Synopsis
  • English is considered a global language, but learning it as a second language is still challenging for speakers of languages like Japanese, which are distantly related to English.
  • Previous studies on language translation have shown brain activation in areas like Broca's area and the dorsolateral prefrontal cortex, mainly for languages with closer linguistic connections.
  • Using fNIRS, this study found that brain activation patterns during Japanese to English translation varied significantly based on English proficiency, with advanced learners showing specific activation in Broca's area for low-familiarity words, while elementary learners activated the left temporal area regardless of familiarity.
