Abstract: Standing on textured materials can improve static balance, potentially by modulating somatosensory inputs from the soles of the feet. To synthesise and quantify the immediate effects of textured materials on static balance in healthy young and older adults. Primary outcomes were the centre of pressure (COP) displacement and velocity, during eyes open and eyes closed conditions. Ten crossover studies (n = 318, 58% female) met the inclusion criteria. A random effects meta-analysis model derived pooled standardised mean differences (SMD Hedges g) to quantify the effects of textured materials. Heterogeneity was quantified with the tau-statistic (τ). A 95% prediction interval quantified the likely range of true effects on COP outcomes in similar future studies. There was a small to moderate beneficial effect for textured materials vs control conditions in: COP displacement during both eyes open (SMD: 0.29 95% CI -0.06 to 0.64 τ = 0.32) and eyes closed (SMD: 0.75 95% CI 0.18 to 1.33 τ = 0.55). A trivial to small beneficial effect was observed in COP velocity during eyes open (SMD: 0.14 95% CI -0.14 to 0.43 τ = 0.18) and eyes closed (SMD: 0.20 95% CI 0.01 to 0.40 τ = 0.18) for textured materials. The 95% prediction intervals showed texture may not consistently provide beneficial results across studies for all outcomes: COP displacement EC (-0.61 to 2.12), EO (-0.54 to 1.12), COP velocity EC (-0.27 to 0.68) and EO (-0.44 to 0.73). Overall, textured materials improved balance, but these effects were heterogeneous. This research may therefore inform applied investigations into balance improvements for healthy populations, for ex le, in functional movements and sports.

Abstract: Following theories of emotional embodiment, the facial feedback hypothesis suggests that in iduals' subjective experiences of emotion are influenced by their facial expressions. However, evidence for this hypothesis has been mixed. We thus formed a global adversarial collaboration and carried out a preregistered, multicentre study designed to specify and test the conditions that should most reliably produce facial feedback effects. Data from n = 3,878 participants spanning 19 countries indicated that a facial mimicry and voluntary facial action task could both lify and initiate feelings of happiness. However, evidence of facial feedback effects was less conclusive when facial feedback was manipulated unobtrusively via a pen-in-mouth task.
