Professional interpreters show distinct brain activation patterns during simultaneous interpreting (SI). Translating into a non-native language engages more brain regions, particularly in the left hemisphere, compared to native language translation.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Linguistics

Background:

  • Simultaneous interpreting (SI) is a complex cognitive task.
  • Understanding the neural underpinnings of SI is crucial for cognitive neuroscience and linguistics.

Purpose of the Study:

  • To investigate brain activation differences between simultaneous interpreting (SI) and shadowing.
  • To explore how the direction of translation (native vs. non-native language) affects brain activity during SI.

Main Methods:

  • Positron emission tomography (PET) was used to measure brain activation.
  • Professional interpreters performed simultaneous interpreting and shadowing tasks with auditorily presented text.

Main Results:

  • SI into the native language (Finnish) showed increased activation in the left frontal cortex.

  • SI into the non-native language (English) revealed more extensive left-sided fronto-temporal activation.
  • Activation patterns were modulated by translation direction, with greater engagement for non-native language translation.

    • Conclusions:

    • Simultaneous interpreting predominantly activates left-hemispheric structures.
    • These activated regions are associated with lexical search, semantic processing, and verbal working memory.
    • Translating into a non-native language is a more demanding task, reflected in broader brain activation.
