In anthropology, research on human spatial orientation (wayfinding) has centered on two conflicting theories: the "mental map," whereby humans build abstract cognitive representations of the spatial relations between objects, and "practical mastery," which rejects the idea that such abstract representations exist and, in its most developed form, suggests that wayfinding is a process of moving f...

A dominant hypothesis on how the brain processes numerical size proposes a spatial representation of numbers as positions on a "mental number line." An alternative hypothesis considers numbers as elements of a generalized representation of sensorimotor-related magnitude, which is not obligatorily spatial. Here we show that individuals' relative use of spatial and nonspatial representations has ...

A growing body of evidence suggests that people with Alzheimer's Disease (AD) show compromised spatial abilities. In addition, there exists from the earliest stages of AD a specific impairment in "mental frame syncing," which is the ability to synchronize an allocentric viewpoint-independent representation (including object-to-object information) with an egocentric one by computing the bearing ...

Growing evidence points to a bidirectional relationship between spatial distance and level of mental representation, whereby distant (vs. near) events are represented by a higher level of representation, and higher levels of representations increase perceptions of distance. In the current article, we review research that establishes this association and explores its implications. We begin by br...

There is a universal and often unconscious tendency to mentally associate the number sequence with a spatial continuum (the mental number line). Here we study one individual who reports a strong and vivid sense of space when processing numbers. For him, the number sequence has a precise spatial form: a curvilinear right-to-left oriented line. We used various tasks to demonstrate that this numer...

The cognitive representation of a return path is a rather unexplored topic including different issues, e.g., perception, mental imagery, mental spatial processing, and language. We here investigated the return path with landmarks located on different positions (optimal, suboptimal). Participants learned a total of 24 routes and had to produce the return paths (N=20). In a second experiment the ...

Human reasoning about spatial environments, sketching and drawing in design , or solving of spatial configuration tasks often involves utilizing external graphical representations such as sketches, maps, or diagrams as well as mental spatio-analogical representations (e.g. in a visuo-spatial format, such as employed and constructed in mental imagery). Processes involved in the reasoning include...

Demographic change in regard to an aging population with an increasing amount of diabetes patients will put a strain on health care rentability in all modern societies. Electronic living assistants for diabetes patients might help lift the burden on taxpayers, if they are usable for the heterogeneous user group. Research has shown that correct mental models of device menu structures might help ...

Mental representation of numbers is believed to be spatial in nature, with small numbers occupying the left and large numbers the right side of a putative mental number line. Consistent with this, presentation of numbers from the low and high ends of the mental number line induces covert shifts of spatial attention to the left and right side of visual space, respectively. However, the effect of...
