Subclaims¶

q3 i3 In Study 1, instructed participants produced significantly more gestures than spontaneous participants, with a large effect size ηp2 = 0.49. → Thakore 2024 q3 i3 In Study 2, the gesture manipulation produced a very large effect size, ηp2 = 0.83. → Thakore 2024 (2)

q3 · i3 · causal · r2

Study 1 mixed design ANOVA manipulation check on gestures produced during reading aloud (N = 100): instructed participants gestured far more (M = 25.88) than spontaneous participants (M = 0.18), "with a large effect size, η p 2 = 0.49".

"those in the instructed gesture condition (M = 25.88, SD = 2.62) produced significantly more gestures than those in the spontaneous gesture condition (M = 0.18, SD = 0.16), F(1, 98) = 95.68, p < 0.001, with a large effect size, η p 2 = 0.49."

Study 2 face-to-face manipulation check (N = 98) confirmed the instruction manipulation: instructed participants produced far more gestures (M = 75.25) than spontaneous participants (M = 3.59), "with a very large effect size, η p 2 = 0.83".

"participants in the instructed gesture condition produced significantly more gestures (M = 75.25, SD = 21.49) than those in the spontaneous gesture condition (M = 3.59, SD = 8.47), F(1, 96) = 471.39, p < 0.001, with a very large effect size, η p 2 = 0.83."

Discussion¶

Related Claims¶

• Instructing adults to gesture while reading narratives aloud hindered free recall relative to spontaneous gesturing (Study 1) — related
• In Study 2, spontaneous gesturing produced better specific recall than instructed gesturing, and negative narratives were recalled better than positive — related
• Gesture instructions impaired narrative recall only for participants with average or above-average verbal memory, not those below average (Study 1) — related
• Emotional valence consistently influences narrative recall, with negative narratives most memorable, while instructed gesturing shows mixed effectiveness — related
