q2 i? The review reports, citing Macedonia et al. (2011), that retention was significantly higher for words accompanied by iconic, semantically congruent gestures than by meaningless gestures. → Manuela Macedonia 2026 q2 i? The review reports, citing García-Gámez and Macizo (2023), that congruent gestures improved noun and verb learning relative to no gestures, whereas meaningless or incongruent gestures hindered performance. → Manuela Macedonia 2026 (2)

q2 · i? · theoretical · r3

The review reports, citing Macedonia et al. (2011), a Vimmi artificial-corpus study in which words were paired with iconic gestures or meaningless self-adaptors; "Retention was significantly higher for words accompanied by the iconic, semantically congruent gestures." fMRI showed iconic gestures recruited broader motor networks.

"Retention was significantly higher for words accompanied by the iconic, semantically congruent gestures."

Learner Variables¶

• Vocabulary — outcome: instruction changes it
