“…B). The present behavioral results thus replicated previous evidence by showing that spatial positions relative to the irrelevant frame of reference were not only represented but also interfered with the spatial judgments relative to the task‐relevant frame of reference [Zhang et al, ].…”

The spatial location of an object can be represented in two frames of reference: egocentric (relative to the observer's body or body parts) and allocentric (relative to another object independent of the observer). The object positions relative to the two frames can be either congruent (e.g., both left or both right) or incongruent (e.g., one left and one right). Most of the previous studies, however, did not discriminate between the two types of spatial conflicts. To investigate the common and specific neural mechanisms underlying the spatial congruency effect induced by the two reference frames, we adopted a 3 (type of task: allocentric, egocentric, and color) × 2 (spatial congruency: congruent vs. incongruent) within-subject design in this fMRI study. The spatial congruency effect in the allocentric task was induced by the task-irrelevant egocentric representations, and vice versa in the egocentric task. The nonspatial color task was introduced to control for the differences in bottom-up stimuli between the congruent and incongruent conditions. Behaviorally, significant spatial congruency effect was revealed in both the egocentric and allocentric task. Neurally, the dorsal-medial visuoparietal stream was commonly involved in the spatial congruency effect induced by the task-irrelevant egocentric and allocentric representations. The right superior parietal cortex and the right precentral gyrus were specifically involved in the spatial congruency effect induced by the irrelevant egocentric and allocentric representations, respectively. Taken together, these results suggested that different subregions in the parieto-frontal network played different functional roles in the spatial interaction between the egocentric and allocentric reference frame.

INTRODUCTION Spatial navigation deficits are reported in dementia, but their temporal relationship to cognitive decline is not established. METHODS Prospective cohort study in 442 non-demented adults (mean age 79.9 years). Spatial navigation measured with the Floor Maze Test, and reported as immediate maze time (IMT) and delayed maze time (DMT). Pre-dementia syndromes, Mild Cognitive Impairment (MCI) and Motoric Cognitive Risk (MCR) syndromes, were primary outcomes. RESULTS Over a mean follow-up of 16.5 ± 13.7 months, 41 participants developed MCI and 30 MCR. In Cox models adjusted for age, sex, education, cognitive status, comorbid illnesses, and maze errors, a 10-second increment on IMT predicted incident MCI (adjusted hazard ratio [aHR] 1.25; 95% CI 1.06 to 1.48) and MCR (aHR 1.53; 95% CI 1.23 to 1.90). DMT predicted MCR but not MCI. DISCUSSION Spatial navigation performance predicted pre-dementia syndromes in aging, and implicates navigational impairments as an early feature in dementias.

“…HI children compensate auditory deprivation highlighting attention to stimuli in the near and far space visual fields (to visual central stimuli in far space and to peripheral visual stimuli in near space) [38,39]. Other adaptation mechanisms in HI children are higher location memory [40] and higher visual and tactile orientation in the allocentric frame of reference (encoding the position of an object in relation to others), which allows a fast attention to targets [38,41]. Nevertheless, the discrimination at midline and lateral positions [29] and the egocentric frame of reference (encoding the position of an object in relation to the own body) seem to be abnormal in HI children.…”

“…Nevertheless, the discrimination at midline and lateral positions [29] and the egocentric frame of reference (encoding the position of an object in relation to the own body) seem to be abnormal in HI children. In this sense, goal-directed movements towards the objects, based in the egocentric frame of reference, are slower than in NH [41]. In addition, auditory deprivation affects brain spatial organization; thus, in contrast with NH children, who have shown right hemisphere activation for spatial attention, an atypical bilateral or left hemisphere activation has been seen in HI children [40,42].…”

Objectives: The aim of this work is to provide a scoping review to compile and classify the systems helping train and enhance psychomotor skills in hearing impaired (HI) children. Methods: Based on an exhaustive review on psychomotor deficits in HI children, the procedure used to carry out a scoping review was: select keywords and identify synonyms, select databases and prepare the queries using keywords, analyze the quality of the works found using the PEDro Scale, classify the works based on psychomotor competences, analyze the interactive systems (e.g., sensors), and the achieved results. Results: Thirteen works were found. These works used a variety of sensors and input devices such as cameras, contact sensors, touch screens, mouse and keyboard, tangible objects, haptic and virtual reality (VR) devices. Conclusions: From the research it was possible to contextualize the deficits and psychomotor problems of HI children that prevent their normal development. Additionally, from the analysis of different proposals of interactive systems addressed to this population, it was possible to establish the current state of the use of different technologies and how they contribute to psychomotor rehabilitation.
