“Where am I?” A snapshot of the developmental topographical disorientation among young Italian adults

In the last decade, several cases affected by Developmental Topographical Disorientation (DTD) have been described. DTD consists of a neurodevelopmental disorder affecting the ability to orient in the environment despite well-preserved cognitive functions, and in the absence of a brain lesion or other neurological or psychiatric conditions. Described cases showed different impairments in navigational skills ranging from topographic memory deficits to landmark agnosia. All cases lacked a mental representation of the environment that would allow them to use high-order spatial orientation strategies. In addition to the single case studies, a group study performed in Canada showed that the disorder is more widespread than imagined. The present work intends to investigate the occurrence of the disorder in 1,698 young Italian participants. The sample is deliberately composed of individuals aged between 18 and 35 years to exclude people who could manifest the loss of the ability to navigate as a result of an onset of cognitive decline. The sample was collected between 2016 and 2019 using the Qualtrics platform, by which the Familiarity and Spatial Cognitive Style Scale and anamnestic interview were administered. The data showed that the disorder is present in 3% of the sample and that the sense of direction is closely related to town knowledge, navigational strategies adopted, and gender. In general, males use more complex navigational strategies than females, although DTD is more prevalent in males than in females, in line with the already described cases. Finally, the paper discusses which protective factors can reduce DTD onset and which intervention measures should be implemented to prevent the spread of navigational disorders, which severely impact individuals’ autonomy and social relationships.

Walking on a minefield: planning, remembering, and avoiding obstacles: preliminary findings

Travel planning (TP) is a kind of planning devoted to spatial orientation that is distinguishable from general planning (GP). It is crucial to reach a destination, since it allows to select the best route according to the environmental features (e.g., the one with little traffic or the safest). TP is also needed to avoid obstacles along the way and to put in place effective strategies to support navigation. TP involves several cognitive processes, such as visuo-spatial and topographic memory as well as other executive functions (i.e., general planning, cognitive flexibility, problem solving, and divergent thinking) and it is affected by internal factors (such as gender, cognitive strategies, age). Here, we focused on the effects of visuo-spatial (VSWM) and topographic (TWM) working memory on TP, using the Minefield Task (MFT), a new tool aimed at testing TP. We tested VSWM, TWM, GP, and TP in 44 college students. First, we checked for gender differences in all the tasks proposed and then assessed the relation among VSWM, TWM, GP, and TP. Results showed that even though gender difference could be found on TWM, GP, and TP, significative correlations emerged among TP, VSWM, and GP as well as a tendency to significance for VSWM and GP in the regression analyses. Though more evidence is needed, these results suggest that when a brand-new route is computed, GP and VSWM can be the most relevant processes, whereas topographic memory was less involved, probably because the MFT does not require to recall a route from memory. The implications of these results in clinical settings are discussed.
