Research Interests:

Keywords: psychophysics, visual perception, saccades, active vision, reading, attention

Before 1999, my main reseach interests concerned the spatio-temporal integration of low level motion signals. (link to publications)

For instance, I studied some perceptual illusions

Barberpole illusion in 3D (from Castet et al., 1999)

After 1999, I worked on the interaction between visual perception and saccadic eye movements (Active Vision). In order to investigate this broad issue, I followed the following axes:

A/ Low Vision and visual deficits (often in relation to eye movements) (link to publications)

Natural Reading, Face recognition

Development of innovative visual aids and rehabilitation methods

Results from Calabrèse et al. (2016)

B/ Reading (with and without eye movements) in normally-sighted subjects + visuo-motor control (link to publications)

Reading Model from Bernard & Castet (2019)

C/ Stable perception of the world despite a non-coherent retinal inflow. (link to publications)

How can we perceive the world in a coherent way although our eyes are continuously moving around at very high speeds thanks to saccades ? What are the respective roles of visual and extra-retinal factors ?

Illustration from Castet, E. (2010). Perception of intrasaccadic motion, in Dynamics of Visual Motion Processing: Neuronal, Behavioral and Computational Approaches. Springer, New York, pp. 213–238.

D/ Dynamics of the coupling between attention and eye movements. (link to publications)

What are the relationships between visuo-attentional processes and saccadic eye movements? What is the temporal dynamics of these processes?

Experimental Paradigm from Filali-Sadouk et al. (2010)
