French speakers exhibit stress deafness, struggling to differentiate word stress. A new short-term memory task effectively assesses individual stress perception differences in French and Spanish speakers.

Area of Science:

  • Linguistics
  • Psycholinguistics
  • Phonetics

Background:

  • French lacks contrastive stress, leading to 'stress deafness' in native speakers.
  • Previous research used a speeded ABX paradigm, effective for group differences but not individual assessment.
  • Individual stress perception assessment is vital for studying bilinguals and trained monolinguals.

Purpose of the Study:

  • To introduce a robust short-term memory sequence repetition task for assessing individual stress deafness.
  • To investigate the influence of memory load and F0 variability on stress perception in French and Spanish speakers.
  • To establish a paradigm capable of differentiating individuals based on their stress perception abilities.

Main Methods:

  • A short-term memory sequence repetition task was developed and administered.

  • Five cross-linguistic experiments were conducted with French and Spanish participants.
  • The paradigm involved distinguishing nonwords differing in stress location under varying memory loads and phonetic variability.
  • Main Results:

    • Stress deafness was found to be dependent on memory load and F0 variability.
    • Experiments 3 and 4 revealed non-overlapping individual results for French and Spanish participants.
    • The proposed paradigm demonstrated its suitability for individual stress deafness assessment.

    Conclusions:

    • The short-term memory sequence repetition task is a reliable method for assessing individual stress deafness.
    • Linguistic background (e.g., contrastive stress in Spanish vs. French) significantly impacts stress perception.
    • This paradigm advances the study of speech perception and individual differences in phonological processing.
