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.

Representativeness of autistic samples in studies recruiting through social media.

In recent years, there has been an increase in the amount of autism research that recruits participants online for example via social media, where it can be difficult to control the composition of the sample that is obtained. There is therefore a risk of sampling bias causing the sample not to be representative. In this article, we investigated whether the risk of sampling bias seems to have practical implications by systematically exploring markers of bias in 36 studies that recruited participants through social media platforms. We examined potential discrepancies in demographics between the autistic participants and what has previously been reported about the autism population in the literature. Specifically, we looked at sex ratio, age at receiving an autism diagnosis, education level, unemployment rate and fraction of individuals with co-occurring intellectual disability. We found that the participants in most of the included studies were unrepresentative on at least one of the demographic variables, indicating sampling bias. Overall we found a tendency for the included studies to have a reversed sex-ratio (more females participating than males), a high age at receiving an autism diagnosis (median of 30 years), and a median of 60% with a college or university education. Our results suggest that selection bias may be present in many of the investigated studies and thus that results from these may not be generalizable to autism in general.

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.
