Vers une aide à la mobilité basée sur la connaissance de l'espace pour les personnes ayant une déficience visuelle
2018
International audience; Cette communication présente un nouveau concept de dispositif d'assistance à la mobilité pour les personnes présentant une incapacité visuelle (PPIV), son implantation dans un simulateur, et son évaluation préliminaire. Ce système, ACCESSPACE, permet de représenter l'essentiel (gist) de l'agencement spatial des alentours immédiats de l'utilisateur, sur une tablette à stimulation tactile. En combinant des données cartographiques, GPS et visuelles, ce système effectue un bi-partitionnement de l'espace (en zones accessibles ou non) et transmet cette information sous forme d'une carte égocentrée augmentée, évoluant en temps réel avec les mouvements de l'utilisateur. L'év…
Spatial Cognition 2020/1: Book of abstracts : August 2-4, 2021, University of Latvia
2021
Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space, such as cognitive and developmental psychology, linguistics, computer science, geography, cartography, philosophy, neuroscience, and education. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation, including topics such as wayfinding, spatial planning, spatial learning, internal and external re…
Commentary: Preliminary Evidence for Training-Induced Changes of Morphology and Phantom Limb Pain
2019
The aim of this study was to investigate whether a special prosthetic training in phantom limb pain patients aimed at increasing the functional use of the prosthesis leads to neural morphological plasticity of brain structures and a reduction in phantom limb pain. For chronic pain disorders, it was shown that morphological alterations due to pain might become at least partially reversed by pain therapies. Phantom limb pain is a chronic pain disorder that is frequently followed by neural plasticity of anatomical brain structures. In our study, 10 patients with amputation of the upper limb participated in a two-week training with a myoelectric prosthesis with somatosensory feedback. Grip stre…

Suomessa vieraan kielen opiskelu aloitetaan tavallisimmin kolmannella luokalla, ja suurimmalle osalle oppilaista tämä kieli on englanti. Tällöin oppilas alkaa rakentaa kuvaa sekä englannin kielestä että itsestään englannin kielen opiskelijana. Onnistumisen kokemukset ovat tässä vaiheessa tärkeitä, ja yksi tapa niiden mahdollistamiseen on oppilaan oppimistyyliä vastaava opetus. Kolmannen luokan englannin oppitunneille osallistuu kuitenkin heterogeeninen ryhmä erilaisia oppijoita, minkä vuoksi on käytettävä vaihtelevia opetusmenetelmiä. Tässä tutkimuksessa keskityttiin seuraaviin oppimistyyleihin: visuaalinen, auditiivinen, kinesteettinen, taktiilinen sekä ryhmässä ja yksin oppiminen. Näistä …
Studying brain visuo-tactile integration through cross-spectral analysis of human MEG recordings
2010
An important aim in cognitive neuroscience is to identify the networks connecting different brain areas and their role in executing complex tasks. In this study, visuo-tactile tasks were employed to assess the functional correlation underlying the cooperation process between visual and tactile regions. MEG data were recorded from eight healthy subjects while performing a visual, a tactile, and a visuo-tactile task. To define regions of interest (ROIs), event-related fields (ERFs) were estimated from MEG data related to visual and tactile areas. The ten channels with the highest increase in ERF variance, moving from rest to task, were selected. Cross-spectral analysis was then performed to a…
A Central Nervous System Focused Treatment Program for People with Frozen Shoulder: A Feasibility Study
2022
Background: Frozen shoulder (FS) is a highly disabling pathology of poorly understood etiology, which is characterized by the presence of intense pain and progressive loss of range of motion (ROM). The aim of this study is to evaluate the feasibility and clinical impact of a CNS-focused treatment program for people with FS. Methods: 10 subjects with primary FS received a 10-week CNS-focused intervention including sensory discrimination training and graded motor imagery techniques delivered as clinic sessions (60 min) and home therapy (30 min five times per week). Measurements were taken at baseline, after a 2-week “washout” period, after treatment, and at three months follow-up.…
Studies on adaptation to complete dentures. Part II: Oral stereognosis and tactile sensibility
1995
High oral perception is thought to contribute to poor adaptation to new dentures. The aim of this study was to evaluate the oral stereognosis and tactile sensibility in edentate subjects and relate these to patient age and capability of adaptation to new prostheses. A total of 67 patients were provided with new complete dentures 2-3 weeks before the experiment. In 54 subjects, the oral stereognosis was evaluated by 12 different test-pieces, which were placed unseen on the tongue and had to be recognized. In 38 patients, the oral tactile sensibility was determined in the premolar area using copper foils. The capability of adaptation was evaluated by a questionnaire. Denture retention was ass…
Data from: I smell where you walked – how chemical cues influence movement decisions in ants
2016
Interactions between animals are not restricted to direct encounters. Frequently, individuals detect the proximity of others through cues unintentionally left by others, such as prey species assessing predation risk based on indirect predator cues. However, while the importance of indirect cues in predator–prey interactions has been intensely studied, their role in interactions among competitors, and their consequences for community structure, are little known to date. Ant communities are usually structured by aggressive interactions between competing species. Responding to cues of others should be useful to avoid competitors or discover food sources. In ants and other insects, such cues in…
