As Light as You Aspire to Be: Changing body perception with sound to support physical activity

Supporting exercise adherence through technology remains an important HCI challenge. Recent works showed that altering walking sounds leads people perceiving themselves as thinner/lighter, happier and walking more dynamically. While this novel approach shows potential for physical activity, it raises critical questions impacting technology design. We ran two studies in the context of exertion (gym-step, stairs-climbing) to investigate how individual factors impact the effect of sound and the duration of the after-effects. The results confirm that the effects of sound in body-perception occur even in physically demanding situations and through ubiquitous wearable devices. We also show that the effect of sound interacted with participants’ body weight and masculinity/femininity aspirations, but not with gender. Additionally, changes in body-perceptions did not hold once the feedback stopped; however, body-feelings or behavioural changes appeared to persist for longer. We discuss the results in terms of malleability of body-perception and highlight opportunities for supporting exercise adherence

The associations between seventh grade Finnish students’ motivational climate, perceived competence, self-determined motivation, and fundamental movement skills

The aim of the study was to investigate the relationships between motivational climate, perceived competence, self-determined motivation towards physical education (PE) and the fundamental movement skills of Finnish secondary school students. A sample of 370 seventh-grade PE students (girls n = 189; boys n = 181; mean age = 13.08; SD = 0.25) completed measures pertaining to motivational climates, perceived competence, regulation of motivation, and fundamental movement skills. Path analysis revealed results generally consistent with the theoretical tenets of the self-determination and the achievement goal theories by demonstrating that a task-involving motivational climate influenced perceived competence, which in turn affected more self-determined motivation towards PE. Furthermore, results revealed that this motivational sequence was associated with increased balance skill. A sequence consisting of task-involving climate, intrinsically regulated motivation, and balance skills was also observed. Additionally, the results indicated that task-involving motivational climate influenced perceived competence, in turn influencing manipulative and locomotor skills. Finally, an ego-involving climate was found to be a marginally positive predictor of manipulative skills
