In a thought-provoking discussion, Sam Wilkinson, a senior lecturer in philosophy at the University of Exeter, dives into the complexities of mental health and the concept of normality. He challenges traditional notions of mental disorders, proposing that recent cognitive science advancements can redefine irrational behaviors. Wilkinson explores predictive processing and its effects on perception and emotions, while also highlighting the importance of philosophy in psychiatry. He calls for a broader understanding of mental health that acknowledges cultural influences and the intricate nature of cognition.
The podcast emphasizes that recent cognitive science breakthroughs are redefining the understanding of mental disorders, reducing stigma around irrationality.
Sam Wilkinson shares his academic journey through literature and philosophy, highlighting the interdisciplinary nature of cognitive science in understanding the mind.
Predictive processing is presented as a proactive cognitive model, suggesting that many mental health issues stem from failures in regulating prediction errors.
Deep dives
Defining Normalcy and Disorder
The podcast delves into the complexities surrounding the definitions of normal behavior and mental disorders. It highlights that behaviors considered deviant often lead to feelings of helplessness and inadequacy for those experiencing them. Historically, such behaviors have been labeled as irrational or disruptive, but recent advancements in cognitive science are helping to redefine these psychiatric phenomena. These breakthroughs are aimed at reducing stigma while providing a clearer understanding of the nature and causes behind psychological troubles.
The Journey into Cognitive Science
The guest shares his academic journey which began with a passion for literature and evolved into an interest in philosophy and cognitive science. Initially drawn to literature's profound insights, he shifted towards studying philosophy at Oxford, leading him to explore the philosophy of mind and then immerse himself in cognitive science. As he navigated through various disciplines, he began to appreciate the interdisciplinary nature of cognitive science, combining psychology and neuroscience with philosophical inquiries. This journey emphasized the necessity of an empirically informed approach to understand the mind better.
Predictive Processing Explained
The discussion introduces predictive processing as an innovative framework that contrasts with traditional views of cognition. Traditional perspectives often assume that perception is a reaction to external stimuli; however, predictive processing posits that perception is fundamentally anticipatory. In this model, the brain is constantly predicting sensory input, utilizing past experiences to shape current perceptions rather than responding purely to immediate stimuli. This shift in understanding highlights how cognition is a proactive process aimed at minimizing prediction errors, thereby influencing how individuals interact with their world.
Implications for Mental Health
The application of predictive processing to mental health issues offers exciting insights into understanding and treating conditions like schizophrenia and depression. By framing mental health problems through the lens of prediction errors, researchers propose that many mental health issues arise from a failure to effectively regulate these errors. This perspective aids in elucidating the mechanisms behind auditory hallucinations and delusions, suggesting that individuals with such experiences might misinterpret their predictions about sensory input. This shift focuses on addressing the underlying cognitive processes rather than merely the observable symptoms associated with mental disorders.
The Role of Philosophy in Psychiatry
Philosophy contributes significantly to the field of psychiatry by providing clarity and promoting integrative approaches among various disciplines. Philosophers can clarify conceptual confusions within psychiatric research, enabling a more cohesive understanding of mental health issues. Additionally, philosophy encourages critical thinking about the societal and institutional factors influencing psychiatric practices, which can help identify systemic biases in treatment and diagnosis. The integration of philosophical perspectives is crucial for re-examining assumptions about mental health, ensuring that the field evolves in a nuanced and comprehensive manner.
What is normal? What is a disorder? Often, when we interact with people who behave in ways we cannot understand, the question of defining ‘normal’ and sane behaviour becomes apparent. Importantly, when we ourselves exhibit thoughts and behaviours which are viewed as deviant from the commonly accepted definition of normality, we might feel helpless, judged, and inadequate. Historically, behaviours that are diagnostic of mental disorders were viewed as irrational or disruptive. However, recent breakthroughs in cognitive science can shed new light on redefining psychiatric phenomena while erasing the stigma of irrationality. What are these breakthroughs? What goes into elucidating the nature and causes of the many psychological troubles with which one can be faced? Are delusions and other kinds of thoughts really irrational?
He is Sam Wilkinson, a senior lecturer in philosophy at the department of sociology, philosophy and anthropology at the University of Exeter in the United-Kingdom. He received his PhD at Edinburgh University and did a postdoc at Durham University on the phenomenon of hearing voices. Currently, he is visiting the Institut Jean Nicod. His work lies at the intersection of the philosophy of cognitive science and the philosophy of psychiatry. He has published papers on the topics of predictive processing approaches to studying cognition, psychosis, hallucinations, trauma, and much more.
