Subclaims¶

q3 i? In Study 1 free recall, gesture condition interacted with verbal memory such that instructed gesturing was detrimental at mean and +1 SD verbal memory but not at −1 SD. → Thakore 2024 q3 i? In Study 1 specific recall, the gesture-by-verbal-memory interaction was significant, with spontaneous gesturing better only at +1 SD verbal memory. → Thakore 2024 (2)

q3 · i? · causal · r2

Linear mixed model on Study 1 free recall (N = 100) with VM as continuous predictor. The article reports "a significant interaction between gesture and VM, χ2(1) = 23.38, p < 0.001", with no gesture effect at −1 SD VM but spontaneous better at mean and +1 SD VM.

"However, there was a significant interaction between gesture and VM, χ2(1) = 23.38, p < 0.001 (see Fig. 1). For VM one standard deviation below the mean, gesture condition did not impact recall, χ2(1) = 1.41, p = 0.234."

q3 · i? · causal · r2

Study 1 specific recall model showed a significant gesture × VM interaction, χ2(1) = 4.23, p = 0.040; simple effects showed no condition difference at low or mean VM, and "participants in the spontaneous gesture condition had significantly better recall" at +1 SD VM.

"For those with VM one standard deviation above the mean, however, participants in the spontaneous gesture condition had significantly better recall than those in the instructed gesture condition, χ 2(1) = 6.39, p = 0.012."

• Emotional valence benefited narrative recall: negative narratives were recalled best and neutral narratives worst (Study 1) — related
• Gesture instructions hindered specific recall for participants with lower propensity to gesture (Study 2) — related
• Instructing adults to gesture while reading narratives aloud hindered free recall relative to spontaneous gesturing (Study 1) — related
• Gesture manipulation checks confirmed instructed participants gestured far more than spontaneous participants in both studies — related
