new book – ‘The Measure of Madness: Philosophy of Mind, Cognitive Neuroscience, and Delusional Thought’ by Philip Gerrans

July 12, 2014

The Measure of Madness

The Measure of Madness: Philosophy of Mind, Cognitive Neuroscience, and Delusional Thought (Life and Mind: Philosophical Issues in Biology and Psychology) by Philip Gerrans (Bradford Book/MIT, 2014)

(amazon.co.uk)

Book description from the publisher:

In The Measure of Madness, Philip Gerrans offers a novel explanation of delusion. Over the last two decades, philosophers and cognitive scientists have investigated explanations of delusion that interweave philosophical questions about the nature of belief and rationality with findings from cognitive science and neurobiology. Gerrans argues that once we fully describe the computational and neural mechanisms that produce delusion and the way in which conscious experience and thought depend on them, the concept of delusional belief retains only a heuristic role in the explanation of delusion.

Gerrans proposes that delusions are narrative models that accommodate anomalous experiences. He argues that delusions represent the operation of the Default Mode Network (DMN) — the cognitive system that provides the raw material for humans’ inbuilt tendency to provide a subjectively compelling narrative context for anomalous or highly salient experiences — without the “supervision” of higher cognitive processes present in the nondelusional mind. This explanation illuminates the relationship among delusions, dreams, imaginative states, and irrational beliefs that have perplexed philosophers and psychologists for over a century. Going beyond the purely conceptual and the phenomenological, Gerrans brings together findings from different disciplines to trace the flow of information through the cognitive system, and applies these to case studies of typical schizophrenic delusions: misidentification, alien control, and thought insertion. Drawing on the interventionist model of causal explanation in philosophy of science and the predictive coding approach to the mind influential in computational neuroscience, Gerrans provides a model for integrative theorizing about the mind.

new book – ‘Suspicious Minds: How Culture Shapes Madness’ by Joel & Ian Gold

July 9, 2014

Suspicious Minds

Suspicious Minds: How Culture Shapes Madnessby Joel Gold and Ian Gold (Free Press, 2014)

(kindle ed.), (amazon.co.uk)

Book description from the publisher:

Combining extraordinary true stories with the latest research, Joel and Ian Gold take us on a wild journey through the delusional brain to explore the intersection of neuroscience, biology, and culture.

Mr. A. was admitted to Dr. Joel Gold’s inpatient unit at Bellevue Hospital in 2002. He was, he said, being filmed constantly, and his life was being broadcast around the world “like The Truman Show”—the 1998 film depicting a man who is unknowingly living out his life as the star of a popular soap opera. Over the next few years, Gold saw a number of patients suffering from what he and his brother, Dr. Ian Gold, began calling the “Truman Show Delusion,” launching them on a quest to understand the nature of this particular phenomenon, of delusions more generally, and the nature of madness itself.

The current view of delusions is that they are the result of biology gone awry, of neurons in the brain misfiring. In contrast, the Golds argue, delusions are in fact the result of the interaction between the brain and the social world. By exploring the major categories of delusion via fascinating case studies and marshaling the latest research in schizophrenia, the brothers reveal the role of culture and the social world in the development of psychosis, notably delusions. The result is a groundbreaking new direction for thinking about the interaction of the brain and the world around us.

Sure to appeal to those who admire the work of Oliver Sacks, Steven Pinker, and Antonio Damasio, Suspicious Minds presents a fascinating study about just how dramatically our surroundings can influence our brains.

new book – ‘The Innocent Eye: Why Vision Is Not a Cognitive Process’ by Nico Orlandi

July 8, 2014

The Innocent Eye

The Innocent Eye: Why Vision Is Not a Cognitive Process (Philosophy of Mind Series) by Nico Orlandi (Oxford University Press, 2014)

(kindle ed.), (amazon.co.uk), (UK kindle ed.)

Book description from the publisher:

Why does the world look to us as it does? Generally speaking, this question has received two types of answers in the cognitive sciences in the past fifty or so years. According to the first, the world looks to us the way it does because we construct it to look as it does. According to the second, the world looks as it does primarily because of how the world is. In The Innocent Eye, Nico Orlandi defends a position that aligns with this second, world-centered tradition, but that also respects some of the insights of constructivism. Orlandi develops an embedded understanding of visual processing according to which, while visual percepts are representational states, the states and structures that precede the production of percepts are not representations.

If we study the environmental contingencies in which vision occurs, and we properly distinguish functional states and features of the visual apparatus from representational states and features, we obtain an empirically more plausible, world-centered account. Orlandi shows that this account accords well with models of vision in perceptual psychology — such as Natural Scene Statistics and Bayesian approaches to perception — and outlines some of the ways in which it differs from recent ‘enactive’ approaches to vision. The main difference is that, although the embedded account recognizes the importance of movement for perception, it does not appeal to action to uncover the richness of visual stimulation.

The upshot is that constructive models of vision ascribe mental representations too liberally, ultimately misunderstanding the notion. Orlandi offers a proposal for what mental representations are that, following insights from Brentano, James and a number of contemporary cognitive scientists, appeals to the notions of de-coupleability and absence to distinguish representations from mere tracking states.
