On the coupling between agent internal and agent/ environmental dynamics: Development of spatial representations in evolving autonomous robots

2008

In this article we describe how a population of evolving robots can autonomously develop forms of spatial representation which allow them to self-localize and to discriminate different locations of their environment by integrating sensory-motor information over time. The evolving robots also display a remarkable ability to generalize their skill in new environmental conditions that they have never experienced before. The analysis of the obtained results indicates that the evolved robots come up with simple and robust solutions that exploit quasi-periodic limit cycle dynamics emerging from the coupling between the robot/environmental dynamics and a robot's internal dynamics. More specifical…

Les représentations spatiales de concepts scientifiques : inventaire et diversité

1994

The consultation of twelve journals (French and English language) that deal with science education, for the years 1991 to 1993, allowed us to summarize the use of spatial representations of scientific concepts in didactics research. Two main results were produced from this study : there has not been much work published with spatial representations, and what has been published is very heterogeneous. Analysis of this diversity does not always allow us to understand the authors’ objectives and obliges researchers in didactics to think about the nature and role of spatial representations in the construction of scientific knowledge.

Developmental dyslexia and vision

2013

International audience; Developmental dyslexia affects almost 10% of school-aged children and represents a significant public health problem. Its etiology is unknown. The consistent presence of phonological difficulties combined with an inability to manipulate language sounds and the grapheme-phoneme conversion is widely acknowledged. Numerous scientific studies have also documented the presence of eye movement anomalies and deficits of perception of low contrast, low spatial frequency, and high frequency temporal visual information in dyslexics. Anomalies of visual attention with short visual attention spans have also been demonstrated in a large number of cases. Spatial orientation is als…
