q3 i? In Study 2, the interaction between gesture condition and propensity to gesture was significant, with instructed gesturing harming recall for participants one SD below the mean in propensity to gesture. → Thakore 2024

q3 · i? · causal · r2

Face-to-face experiment with 98 participants who first retold a cartoon to measure naturalistic propensity to gesture, then read narratives aloud. The mixed model showed "the interaction between gesture condition and propensity to gesture was significant χ2(1) = 6.89, p = 0.008"; the simple-effect sentence is truncated in the supplied text.

"The interaction between gesture condition and propensity to gesture was significant χ2(1) = 6.89, p = 0.008 (see Fig. 3)."

Discussion¶

Related Claims¶

• Gesture instructions impaired narrative recall only for participants with average or above-average verbal memory, not those below average (Study 1) — related
• Propensity to gesture and verbal memory positively predicted free recall, and the two were uncorrelated (Study 2) — related
• In Study 2, spontaneous gesturing produced better specific recall than instructed gesturing, and negative narratives were recalled better than positive — related
• Instructing adults to gesture while reading narratives aloud hindered free recall relative to spontaneous gesturing (Study 1) — related
• Emotional valence consistently influences narrative recall, with negative narratives most memorable, while instructed gesturing shows mixed effectiveness — related
• Gesture effects on narrative comprehension are not moderated by total task difficulty or age when measured through free recall and specific questions — related
• Observing and producing gestures can enhance comprehension of verbal messages including narratives — related
