Laurent Mottron Laboratory

My research group explores how autistic people process information from early development through adulthood. We are therefore interested in describing the perceptual, memory and reasoning mechanisms by which autistic people perceive the world, construct representations and manipulate them. Our ultimate goal is to facilitate the integration of autistic people into society whatever their age, whilst respecting their differences.

Prototypical autism: New diagnostic criteria and asymmetrical bifurcation model

Article from Laurent Mottron and David Gagnon in Acta Psychologica

The current formulation of the "autism spectrum" generates considerable diagnostic heterogeneity, which can hinder intervention and the advancement of basic research. In this article, we propose new diagnostic criteria for "prototypical" autism between the ages of 2 and 5.
In our reformulation work, we suggest a new conception of autism, in which we propose that it is a human possibility arising from a developmental bifurcation. Prototypical autism would follow a developmental trajectory marked by a progressive decline in social biases, starting at the end of the 1st year, then bifurcate towards a prototypical autistic presentation in the second half of the 2nd year of life. The integration of autism into asymmetrical developmental bifurcations would explain the absence of deleterious neurological and genetic markers, and the presence of familial transmission in canonical autistic presentations.

Drawings by Denis Boudouard (EC in the scientific literature)

EC was an autistic man who passed away in the 1990s, and possessed the ability to draw inanimate objects in 3D. His drawings were almost always done on A4 paper using black fine felt-tip or ballpoint pens, with little color. Without using a ruler, or ever needing to touch up his work, EC was able to trace perfect lines, circles and ellipses. He was also able to draw an object as it rotated through space, without needing to manipulate or walk around the object. Motors, explosions and angry women were recurrent themes in EC’s work. A project looking into his exceptional skills (Mottron & Belleville, 1993, 1995) lay the groundwork for models of perceptual “overfunctioning” in autism.
