Articulation posture influences pitch during singing imagery.

Facial muscle activity contributes to singing and to articulation: in articulation, mouth shape can alter vowel identity; and in singing, facial movement correlates with pitch changes. Here, we examine whether mouth posture causally influences pitch during singing imagery. Based on perception-action theories and embodied cognition theories, we predict that mouth posture influences pitch judgments even when no overt utterances are produced.

A multi-lab test of the facial feedback hypothesis by the Many Smiles Collaboration.

Following theories of emotional embodiment, the facial feedback hypothesis suggests that individuals' 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.

Asymmetrical friendships? People are willing to risk COVID-19 infection from friends but are reluctant to pass it on to them.

Although most protective behaviors related to the COVID-19 pandemic come with personal costs, they will produce the largest benefit if everybody cooperates. This study explores two interacting factors that drive cooperation in this tension between private and collective interests. A preregistered experiment ( = 299) examined (a) how the quality of the relation among interacting partners (social proximity), and (b) how focusing on the risk of self-infection versus onward transmission affected intentions to engage in protective behaviors.

Putting the pieces together: Self-control as a complex interaction of psychological processes.

Ainslie's account of willpower addresses many important mechanisms (e.g., habit, visceral activation, and implementation intention).

Specifying separation: avoidance, abstraction, openness to new experiences.

Lee and Schwarz suggest grounded procedures of separation as a mechanism for embodied cleansing. We compare this process to other mechanisms in grounded cognition and suggest a broader conceptualization that allows integration into general cognitive models of social behavior. Specifically, separation will be understood as a mindset of completed avoidance resulting in high abstraction and openness to new experiences.
