The SACCADE™ model

SACCADE™ is a theoretical model of autism based on the hypothesis of the internal structure of autistic thought (Harrisson 1992; Harrisson and St-Charles 2010). The hypothesis was initially borne from Brigitte Harrisson's experience as an individual with autism.

The SACCADE™ model developed from a collaboration between Brigitte Harrisson and Lise St-Charles who, together, have decades of professional experience working with people with autism. Their clinical observations concerning the distinct ways that individuals with autism process information and learn and interact have helped shape and inform the SACCADE™ model.

SACCADE™ provides a holistic understanding of autistic functioning. Our emerging model is continually refined according to the latest research data in both neuroscience and cognitive science in order to propose a perspective of the typical evolution of autistic manifestations.

The SACCADE™ model is also a neurodevelopmental intervention model that offers cognitive and remedial pedagogical interventions, including using a written code called the SACCADE Conceptual Language™ (SCL™). Our model allows people with autism to access information, communication, and the perception of emotions.

Our unique and comprehensive intervention model has been garnering clinical success since 2007!

The SACCADE™ acronym

SACCADE™ is a French-language acronym that stands for: Structure et Apprentissage Conceptuel Continu Adapté au Développement Évolutif, or, in English, the Structure and Continuous Conceptual Learning Adapted to Evolutionary Development.

SACCADE™ is focused on harmonizing the development of the autistic structure and on the professional development of intervention specialists and others who may work with autistic individuals. Building bridges and fostering collaboration between professionals, parents, and individuals with autism is central to our model.
