Exploring Vermeulen's Predictive Coding Theory and Its Insights into Autism

By Dr. Stephanie Holmes

The study of autism spectrum disorder (ASD) has been a topic of intense research and speculation for decades. While the exact causes and mechanisms underlying autism remain complex and multifaceted, various theories have emerged to shed light on this enigmatic condition. One such theory that has gained traction in recent years is the Predictive Coding Theory, proposed by Dutch cognitive scientist Karl Friston and expanded upon by Henry Markram and Peter Vermeulen. This theory offers a unique perspective on understanding how the brain processes information and how disruptions in this process could potentially contribute to the characteristics of autism. In this blog post, we will delve into Vermeulen's interpretation of Predictive Coding Theory and its implications for our understanding of autism.

Predictive Coding Theory: A Brief Overview

Predictive Coding Theory is a framework that seeks to explain how the brain processes sensory information and makes predictions about the external world. At its core, this theory suggests that the brain continuously generates predictions about incoming sensory data and compares these predictions with the actual sensory input it receives. Any discrepancies between predictions and actual sensory information lead to adjustments in the brain's internal model of the world, allowing it to refine its predictions over time. This predictive process occurs at multiple levels of neural processing, creating a hierarchy of predictions that range from low-level sensory details to higher-level conceptual interpretations.

Vermeulen's Interpretation in the Context of Autism

Peter Vermeulen, an expert in the field of autism education and consultancy, has applied Predictive Coding Theory to the study of autism, offering a fresh perspective on the cognitive and sensory differences observed in individuals on the spectrum. He suggests that autism could be conceptualized as a "perceptual and cognitive style" rather than a disorder, emphasizing the unique way individuals with autism process and interact with their environment.

Sensory Sensitivities and Perceptual Filtering:

One hallmark of autism is sensory sensitivities, where individuals might experience heightened or diminished sensory responses to various stimuli. Vermeulen's interpretation of Predictive Coding Theory suggests that these sensitivities could stem from differences in how sensory information is processed and filtered through predictive mechanisms. In typical individuals, the brain's predictions help filter out irrelevant or expected sensory inputs, allowing the individual to focus on novel or salient information. However, in individuals with autism, these predictive filters might function differently, leading to either an overwhelming flood of sensory data or an overly narrowed focus on specific details.

For example, a person with autism might be hypersensitive to certain sounds or textures due to a reduced ability to predict and filter out these sensory inputs. Alternatively, they might hyper-focus on specific details within their environment, such as the intricate pattern on a piece of fabric, because their brain's predictive mechanisms prioritize these details over broader contextual information.

Context Processing and Social Interaction

Vermeulen's perspective also provides insights into the social and communication challenges often experienced by individuals with autism. Predictive Coding Theory proposes that the brain generates predictions not only about sensory inputs but also about the context in which those inputs occur. In social interactions, these contextual predictions play a crucial role in understanding others' intentions, emotions, and mental states. However, in individuals with autism, this predictive process might be disrupted, leading to difficulties in deciphering social cues and intentions.

Vermeulen suggests that individuals with autism might struggle to generate accurate predictions about social contexts, leading to challenges in recognizing non-verbal cues, understanding sarcasm, and grasping the intentions behind others' actions. This could contribute to the social communication difficulties often observed in individuals with autism.

Preference for Repetitive Behaviors

Another characteristic of autism is a preference for repetitive behaviors and routines. Predictive Coding Theory offers a unique explanation for this phenomenon by highlighting the role of prediction errors. According to this theory, when predictions do not align with incoming sensory information, prediction errors occur. These errors drive learning and adaptation, leading the brain to update its internal model to better match the observed reality.

In the context of autism, repetitive behaviors might serve as a way to reduce prediction errors and create a sense of predictability and control. Engaging in familiar and repetitive activities could provide individuals with autism with a structured environment where sensory inputs are more aligned with their predictions, minimizing the discomfort caused by unpredictable or unexpected stimuli.

Implications for Education and Support

Vermeulen's application of Predictive Coding Theory to autism has significant implications for education and support strategies for individuals on the spectrum. Recognizing autism as a perceptual and cognitive style rather than a mere collection of deficits allows educators, therapists, and caregivers to tailor interventions that accommodate and leverage individuals' unique processing patterns.

Sensory-Friendly Environments

Understanding the role of predictive mechanisms in sensory sensitivities can guide the creation of sensory-friendly environments. By minimizing overwhelming stimuli and providing controlled sensory experiences, educators can help individuals with autism regulate their sensory inputs and reduce distress.

Social Skills Interventions

Vermeulen's insights into social prediction mechanisms can inform the development of effective social skills interventions. Educators can focus on teaching individuals with autism how to generate more accurate predictions about social contexts, improving their ability to recognize emotional cues and understand social dynamics.

Embracing Special Interests

Instead of discouraging repetitive behaviors and special interests, educators and caregivers can acknowledge their role in reducing prediction errors and providing comfort. These interests can be incorporated into learning experiences, helping individuals with autism engage more effectively in educational activities.


Vermeulen's interpretation of Predictive Coding Theory offers a novel perspective on the cognitive and sensory differences seen in individuals with autism. Viewing autism as a distinct perceptual and cognitive style, rather than a set of deficits, opens new doors for understanding and supporting individuals on the spectrum. By exploring how predictive mechanisms shape sensory processing, social interactions, and repetitive behaviors, researchers, educators, and caregivers can develop more effective strategies for enhancing the lives of individuals with autism. This framework not only enriches our understanding of autism but also paves the way for a more inclusive and empathetic approach to supporting neurodiversity.
