Facial expressions are potent social cues that can induce behavioral dispositions, such as approach-avoidance tendencies. We studied these tendencies by asking participants to make whole-body forward (approach) or backward (avoidance) steps on a force plate in response to the valence of social cues (happy or angry faces) under affect-congruent and incongruent mappings. Posturographic parameters of the steps related to automatic stimulus evaluation, step initiation (reaction time), and step execution were determined and analyzed as a function of stimulus valence and stimulus-response mapping. The main result was that participants needed more time to initiate a forward step towards an angry face than towards a smiling face (which is evidence of a congruency effect), but with backward steps, this difference failed to reach significance. We also found a reduction in spontaneous body sway prior to the step with the incongruent mapping. The results provide a crucial empirical link between theories of socially induced action tendencies and theories of postural control and suggest a motoric basis for socially guided motivated behavior.

Introduction: Prior research shows that in-person exposure to electronic nicotine delivery systems (ENDS) use increases desire for cigarettes and ENDS. However, less is known about the impact of cues delivered during remote interactions. This study extends previous in-person cue work by leveraging a remote confederate-delivered cue-delivery paradigm to evaluate the impact of dual nicotine vaping (vs.

It is the continuation of a previous acoustic study that revealed that Northern Raglai onset stops maintain a voicing distinction accompanied by weak formant and voice quality modulations on following vowels, while Southern Raglai has transphonologized this voicing contrast into a register contrast marked by vowel and voice quality distinctions. Our findings indicate that the two dialects partially differ in their use of identification cues, Northern Raglai listeners using both voicing and F1 as major cues while Southern Raglai listeners largely focus on F1.

Circadian clocks in the body drive daily cycles in physiology and behavior. A master clock in the brain maintains synchrony with the environmental day-night cycle and uses internal signals to keep clocks in other tissues aligned. Work in cell cultures uncovered cyclic changes in tissue oxygenation that may serve to reset and synchronize circadian clocks.

Sexual and gender minority (SGM) cancer survivors face unmet care needs in accessing cancer health information and social support despite high satisfaction with treatment. SGM patients often delay care due to concerns of discrimination in healthcare settings, though the care experiences of SGM skin cancer survivors are less known. SGM individuals, particularly sexual minority men, report higher skin cancer prevalence and related risk behaviors than heterosexual men.

Background: The countries within the Greater Mekong Region of Southeast Asia have pledged to eliminate malaria by 2030. Elimination of Plasmodium vivax malaria is challenging as it requires radical cure to prevent relapse. Understanding and facilitating adherence to primaquine radical cure regimens is necessary for malaria elimination.
