Most studies on magnitude representation have focused on the visual modality with no possibility of disentangling the influence of visuo-spatial skills and short-term memory (STM) abilities on quantification processes. This study examines this issue in patients with Turner syndrome (TS), a genetic condition characterized by a specific cognitive profile frequently associating poor mathematical a...

A tablet-based fluoroscopy simulator offers the opportunity to practice percutaneous pinning of supracondylar fractures. Acquiring skills in visuo-spatial and hand-eye coordination are central development safe surgical technique. Mobility ease setup without need for real enables repetition procedure at a time suit residents' schedule.

Does the human capacity for mathematical intuition depend on linguistic competence or on visuo-spatial representations? A series of behavioral and brain-imaging experiments provides evidence for both sources. Exact arithmetic is acquired in a language-specific format, transfers poorly to a different language or to novel facts, and recruits networks involved in word-association processes. In con...

Baumgartner and colleagues (this issue) report a replication of an ERP study by Kelly, Gomez-Ramirez, and Foxe (2008). Unlike the original authors, they failed to observe a significant modulation of the C1 by visuo-spatial attention. They conclude that initial afferent processing in V1 is impermeable to visuo-spatial attention. Although their study, like any replication effort, is valuable and ...

A patient with left visuo-spatial neglect after right fronto-parietal haemorrhage failed to cross out stimuli in left space on cancellation tests. Her bisections of horizontal lines were displaced significantly to the right of true centre. On drawing and copying tasks, she sometimes omitted features on the left (neglect) and sometimes transposed them to right space (allochiria). This co-occurre...

This study investigates the development of visuo-spatial memory in school-aged children, as measured by the Nine Box Maze Test Child Version (NBMT-CV). This task, originally developed for adults by, utilises an allocentric framework to assess the complexities of spatial memory. Sixty children participated in this study (aged 5-12 years), which also involved administration of traditional 'non-ve...

A 31-year-old woman presented slowly progressing ataxia and neurasthenic symptoms after 14-year occupational exposure to low concentration toluene vapour. Examination disclosed only cerebellar signs. Cognitive functions were normal except moderate visuo-spatial and constructive deficit. CT imaging showed severe pancerebellar atrophy without pathological signs in other brain structures. Two year...

Users performance when seeking for information in two information spaces of different design was correlated with their cognitive abilities, and their geographic orientation ability. One of the information spaces had a visuo-graphical interface, and the other a verbal interface. The results showed that correlations with spatial abilities and with geographical abilities were found only for the vi...

Visuo is an implemented Python program that models visual reasoning. It takes as input a description of a scene in words (e.g., “small dog on a sunny street”) and produces estimates of the quantitative magnitudes of the qualitative input (e.g., the size of the dog and the brightness of the street). We claim that reasoners transfer quantitative knowledge to new concepts from distributions of fam...

A modular method is proposed to learn and transfer visuo-motor policies from simulation to the real world in an efficient manner by combining domain randomization and adaptation. The feasibility of the approach is demonstrated in a table-top object reaching task where a 7 DoF arm is controlled in velocity mode to reach a blue cuboid in clutter through visual observations. The learned visuo-moto...
