One set of headwinds from within, one from without — not to mention the basic influence of competition.

I had the chance to live in many countries throughout my life: France, Russia, Canada, China. We believe that photography is an art form in itself and that the beauty of a photograph is found in the entire creative process. That's why we give a lot of importance to the models we work with, the location and the artistic direction. We aspire to pass on our knowledge and learning techniques through these workshops; focusing on spending a nice moment of sharing and creation. For the launch of these workshops, we have selected an ideal location for photography: bright, spacious with studio spaces and natural light, different sets with a New York loft-style only 45min by train from Paris. Workshop Workshop in collaboration with Julian Amieva on the 1st of Octobre To be informed about the workshop An email with all the details will be sended to you.

Federal government websites often end in. The site is secure. Evolution of landmark-based spatial navigation across the human lifespan. Open Science Framework. Human spatial cognition has been mainly characterized in terms of egocentric body-centered and allocentric world-centered wayfinding behavior. It was hypothesized that allocentric spatial coding, as a special high-level cognitive ability, develops later and deteriorates earlier than the egocentric one throughout lifetime. We challenged this hypothesis by testing the use of landmarks versus geometric cues in a cohort of 96 deeply phenotyped participants, who physically navigated an equiangular Y maze, surrounded by landmarks or an anisotropic one. The results show that an apparent allocentric deficit in children and aged navigators is caused specifically by difficulties in using landmarks for navigation while introducing a geometric polarization of space made these participants as efficient allocentric navigators as young adults. This finding suggests that allocentric behavior relies on two dissociable sensory processing systems that are differentially affected by human aging. Whereas landmark processing follows an inverted-U dependence on age, spatial geometry processing is conserved, highlighting its potential in improving navigation performance across the lifespan. Human navigation strategies and the underlying spatial representations have been the subject of an intense debate Burgess, ; Wang and Spelke, ; Ekstrom et al. Wayfinding behavior has extensively been described in terms of two types of navigation strategies, depending on the spatial reference frame in which multisensory representations are encoded. The study of age-related differences in human navigation has added a new temporal dimension to this research domain.

To summarize, in the landmark condition children and older adults adopted direct paths to the goal as young adults, but it nevertheless took them longer, likely reflecting a lower confidence in taking decision when facing the environment composed of landmarks see below for the analysis of oculomotor behavior supporting this conclusion. Subjects were randomly assigned to either the landmark or geometry condition under the constraint of equal gender distribution. Adult participants were all tested in the Streetlab experimental platform at the Vision Institute see Videos 1 — 2. We have now used a different the colormap a more discretized one to increase the readability of the gaze behavior map during the navigation period. Age-Related reweighting of visual and vestibular cues for vertical perception. Allocentric older navigators had a similar gazing behavior during reorientation, but they also looked at the circle during navigation Figure 5c , center and Figure 5—figure supplement 1b.

Flexible use of allocentric and egocentric spatial memories activates differential neural networks in mice. The findings in the article show that when provided with geometric cues, rather than landmark cues, older adults and children no longer show selective difficulty with learning spatial layouts allocentrically. The source data for this figure is available in the Figure 2—source data 1. Figure 5 is dedicated to probe trials only, which is now indicated more clearly by subheadings.

Aging and spatial navigation: what do we know and where do we go? Since the circle was directly in front of the departure position during learning, this suggested that allocentric older participants might use a cue-based i. Likewise, Figure 7A and 7B suggest that there was substantially more variability in gaze altitude during the orientation phase in the landmark condition compared to the geometric condition both between- and, perhaps more importantly, within-groups. Drop-out occurred for several reasons that are usual for aging cohort study populations e. The complete set of 19 measurements was not conducted for all participants included in the study at the moment of the navigation experiments.
