q2 i? Adults recalling a route from auditory descriptions and gestures benefited more from observing gestures when the gestures provided complementary (nonredundant) rather than redundant information. → Juan C. Castro-Alonso 2024

q2 · i? · review · r2

The review reports, citing Austin et al. (2018), an experiment with 125 adults (50% females) recalling a route given with auditory descriptions and gestures, contrasting redundant gesture conditions (e.g., description and gesture both indicating turn right) with nonredundant ones. No effect size is printed.

"As expected, observing the gestures was more effective when these hand movements provided complementary rather than redundant information, as this complementariness allows referential connections (Clark & Paivio, 1991) or mental conversions (Mayer, 2022) in working memory."

Discussion¶

Related Claims¶

• Only low-working-memory-capacity students benefited from making pointing gestures when explaining number equations (review attributes this to Marstaller & Burianová, 2013) — related
• Meaningful pointing gestures produced higher retention scores than beat gestures (review attributes this to Beege et al., 2020) — related
• Redundant speech-gesture cooperation improves recall and social perception more than complementarity — reports the opposite
• Matching modality by conveying complementary information through auditory and visual channels increases retention, transfer, and engagement — a broader claim this one bears on
• Observing gestures embedded in instruction aids learning, especially when gestures convey a different strategy than speech — possibly the same claim (merge candidate)
• Emotionally expressive gestures are associated with better retention than neutral gestures, and gesture and facial expression effects are complementary — related
• Gesture–speech incongruency disrupts multimodal processing, increasing response times and error rates — related
