An investigation into the use of smart home devices, user preferences, and impact during COVID-19.

With the goal of designing smart environments that can support users' physical/mental well-being, we studied users' experiences and different factors that can influence success of smart home devices through an online study conducted during and after the COVID-19 restrictions in June 2021 (109 participants) and March 2022 (81 participants). We investigated what motivates users to buy smart home devices, and if smart home devices may have the potential to improve different aspects of users' well-being. As COVID-19 emphasized a situation where people spent a significant amount of time at home in Canada, we also asked if/how COVID-19 motivated purchase of smart-home devices and how these devices affected participants during the pandemic.

How central and peripheral vision influence focal and ambient processing during scene viewing.

Central and peripheral vision carry out different functions during scene processing. The ambient mode of visual processing is more likely to involve peripheral visual processes, whereas the focal mode of visual processing is more likely to involve central visual processes. Although the ambient mode is responsible for navigating space and comprehending scene layout, the focal mode gathers detailed information as central vision is oriented to salient areas of the visual field.

Anxiety provokes balance deficits that are selectively dopa-responsive in Parkinson's disease.

Previous research has suggested that balance impairments may be linked to anxiety in PD, yet there is little empirical evidence to support this link in PD. This study aimed to evaluate the influence of anxiety on balance, and also examine whether dopaminergic treatment modulates the influence of anxiety on balance. Forty-two participants (10 high anxious PD [HA-PD]; 11 low anxious PD [LA-PD], 21 controls [HC]) performed 10 quiet standing trials on a force platform in two virtual environments: LOW threat; on a plank located on the ground; HIGH threat; on an elevated plank.

Evaluating the Link Between Dopaminergic Treatment, Gait Impairment, and Anxiety in Parkinson's Disease.

Background: Anxiety is the most under-recognized nonmotor symptom of Parkinson's disease (PD), yet it is unclear whether motor impairment exacerbates anxiety observed in PD, or vice versa. The current study examined: (1) whether movement (i.e.

Virtually-induced threat in Parkinson's: Dopaminergic interactions between anxiety and sensory-perceptual processing while walking.

Research evidence has suggested that anxiety influences gait in PD, with an identified dopa-sensitive gait response in highly anxious PD. It has been well-established that accurate perception of the environment and sensory feedback is essential for gait. Arguably since sensory and perceptual deficits have been noted in PD, anxiety has the potential to exacerbate movement impairments, since one might expect that reducing resources needed to overcome or compensate for sensory-perceptual deficits may lead to even more severe gait impairments.
