Based on a targeted literature review, this vision paper emphasizes the importance of dementia-sensitive built space. The article specifically focuses on supporting spatial orientation and wayfinding for people living with dementia. First, we discuss types of wayfinding challenges, underlying processes, and consequences of spatial disorientation in the context of dementia of the Alzheimer’s type. Second, we focus on current efforts aimed at planning and evaluating dementia-sensitive built space, i.e., environmental design principles, interventions, evaluation tools, strategies, and planning processes. Third, we use our findings as a starting point for developing an interdisciplinary research vision aimed at encouraging further debates and research about: (1) the perspective of a person with dementia, specifically in the context of wayfinding and spatial orientation, and (2) how this perspective supplements planning and design processes of dementia-sensitive built space. We conclude that more closely considering the perspective of people with dementia supports the development of demographically sustainable future cities and care institutions.

This article reads William Oldroyd’s Lady Macbeth (2016) through the lens of Michel Foucault’s concept of the heterotopia to explore the film’s ambivalent gender and racial politics. The country house that Katherine Lester is locked away in forms a quasi-heterotopia, mediated through a disorienting cinematography of incarceration. Although she manages to transgress the ideological boundaries surrounding her, she simultaneously contributes to the oppression of her Black housemaid, Anna. On the one hand, the film suggests that the coercive space of the colony—another Foucauldian heterotopia—may threaten white hegemony: While Mr Lester’s Black, illegitimate son Teddy almost manages to claim his inheritance and, hence, contest the racialised master/servant relationship of the country house, Anna’s voice threatens to cause Katherine’s downfall. On the other hand, through eventually denying Anna’s and Teddy’s agency, Lady Macbeth exposes the pervasiveness of intersectional forms of oppression that are at play in both Victorian and twenty-first-century Britain. The constant spatial disorientation that the film produces, this article suggests, not only identifies blind spots in Foucault’s writings on heterotopian space as far as intersectionality is concerned, but also speaks to white privilege as a vital concern of both twenty-first-century feminism and neo-Victorian criticism.

One of the chief features of this global crisis is that we find ourselves in a shifting landscape. The resulting disorientation extends beyond health research and into many domains of our individual and collective lives. We suffer from political disorientation (the need for a radical shift in economic thinking), from social disorientation (the rearrangement of social dynamics based on distancing measures), and from temporal disorientation (the warping of our sense of time during lockdown), to name but a few. This generalised state of disorientation has substantial effects on wellbeing and decision making. In this paper, we review the multiple dimensions of disorientation of the COVID-19 crisis and use state-of-the art research on disorientation to gain insight into the social, psychological and political dynamics of the current pandemic. Just like standard, spatial cases of disorientation, the non-spatial forms of disorientation prevalent in the current crisis consist in the mismatch between our frames of reference and our immediate experience, and they result in anxiety, helplessness and isolation, but also in the possibility of re-orienting. The current crisis provides a unique environment in which to study non-spatial forms of disorientation. In turn, existing knowledge about spatial disorientation can shed light on the shifting landscape of the COVID-19 pandemic.<br /><br />Key messages<br /><ul><li>Growing evidence suggests that the COVID-19 crisis has been disorienting across domains.</li><br /><li>Disorientation is a metacognitive feeling monitoring both spatial and non-spatial tasks.</li><br /><li>Temporal disorientation was fostered by the pandemic’s counterintuitive temporality.</li><br /><li>Disorientation mitigation can facilitate new social and political frames of reference to emerge.</li></ul>

Otolith System

The information coming from the vestibular otolith organs is important for the brain when reflexively making appropriate visual and spinal corrections to maintain balance. Symptoms related to failed balance control and navigation are commonly observed in astronauts returning from space. To investigate the effect of microgravity exposure on the otoliths, we studied the otolith-mediated responses elicited by centrifugation in a group of 25 astronauts before and after 6 mo of spaceflight. Ocular counterrolling (OCR) is an otolith-driven reflex that is sensitive to head tilt with regard to gravity and tilts of the gravito-inertial acceleration vector during centrifugation. When comparing pre- and postflight OCR, we found a statistically significant decrease of the OCR response upon return. Nine days after return, the OCR was back at preflight level, indicating a full recovery. Our large study sample allows for more general physiological conclusions about the effect of prolonged microgravity on the otolith system. A deconditioned otolith system is thought to be the cause of several of the negative effects seen in returning astronauts, such as spatial disorientation and orthostatic intolerance. This knowledge should be taken into account for future long-term space missions.
