Subclaims¶

q2 i? Adults taught novel L2 words by a Good teacher (gazing at the correct object) showed improved post-training performance, especially when they followed his gaze to the correct object. → Ana Zappa 2025 q2 i? Participants were unaware of the gaze manipulation, suggesting reliable referential gaze boosts word-object mapping unconsciously, beyond feedback alone. → Ana Zappa 2025 (2)

q2 · i? · review · r2

A VR eye-tracking study by the authors (Zappa et al., under review) taught adults novel L2 words with Good, Bad, and Random virtual teachers; "Words learned with the Good teacher showed improved performance post-training", particularly with gaze-following. No effect size printed.

"we taught participants novel L2 words with three different virtual teachers: a Good teacher (who gazed at the correct object while producing a word), a Bad teacher (who gazed at the incorrect object), and a Random teacher (who gazed at the correct or incorrect object, randomly) (Zappa et al., under review). All teachers provided reliable social feedback. Words learned with the Good teacher showed improved performance post-train-ing, particularly when participants followed his gaze towards the correct object during learning."

q2 · i? · review · r3

In the same VR study, self-reports showed participants were unaware of the gaze manipulation; the authors interpret this as gaze boosting word-object mapping unconsciously, beyond feedback alone, mirroring L1 joint-attention mechanisms. Authors' interpretation of an as-yet under-review study.

"According to self-reports, participants were unaware of the manipulation. Thus, reliable referential gaze seems to boost the mapping between words and objects unconsciously, beyond feedback alone, mirroring joint attention mechanisms in L1 acquisition."
