Imperfect Cognitions

In this post, Harriet Fagerberg and Justin Garson discuss their new paper, “Proper Functions are Proximal Functions,” forthcoming in The British Journal for Philosophy of Science (preprint  here ). Harriet Fagerberg What makes something a mental disorder? Why are schizophrenia, bipolar disorder, and depression mental disorders, but not jealousy, grief, or racism? This is philosophy of medicine’s famous “demarcation problem.” We think that what makes something a mental disorder, rather than an ordinary response to the problems of life, or run-of-the-mill social deviance, is that there’s a dysfunction. Something in the person’s brain isn’t working as designed. The same is true of the rest of medicine. What makes diabetes or leukemia diseases, rather than just unpleasant things to have (like being short), is that they involve dysfunctions. Justin Garson But what are functions? By ‘function’ we just mean effects that were favored by natural selection. The function of the heart is...

This is a post by Vaughan Bell and gives a summary of a new pre-printed paper called ‘ De-Rationalising Delusions ’ co-authored with Nichola Raihani and Sam Wilkinson .  Vaughan is an Associate Professor in Clinical Psychology at University College London, and also works in the Psychological Interventions Clinic for outpatients with Psychosis (PICuP), in South London and Maudsley NHS Foundation Trust. Nichola Raihani is a Professor in Evolution and Behaviour at University College London, and Sam Wilkinson is a Lecturer in Philosophy at Exeter University.   Historically, delusions have been understood as pathological beliefs that are characterised by their irrationality. Someone who believes, for example, that a camera has been implanted in their tooth and is taking pictures of their mind, would seem, on face value, to have problems in reasoning rationally about the world. This has motivated researchers to look for problems in domain-general reasoning to e...

Today's post is by Eva Jablonka (right) and Simona Ginzburg (left).  Jablonka (Tel-Aviv University) is the coauthor of Evolution in Four Dimensions: Genetic, Epigenetic, Behavioral, and Symbolic Variation in the History of Life and the coeditor of Transformations of Lamarckism: From Subtle Fluids to Molecular Biology, both published by MIT Press.  Ginsburg is a neurobiologist who retired from the Open University of Israel, where she headed the MA Program in Biological Thought. Her recent work focuses on the evolution of early nervous systems and the evolutionary transitions to consciousness in the animal world. In this post they introduce their new book, The Evolution of the Sensitive Soul: Learning and the Origins of Consciousness (MIT Press, 2019). The gap between third-person, scientific, publically shared investigations, such as the neuroscience of echolocation, and first-person subjective experiencing such as echolocation-based subjective ...

This cross-disciplinary symposium on the nature and implications of human and artificial autonomy was organised by Anastasia Christakou and held at the Henley Business School at the University of Reading on 8th May 2019. Josh Bongard (University of Vermont) opened the workshop presenting his research in robotics, where he and his team challenge the Cartesian assumption that body and brain are separate by simulating first, and creating then robots that have body plans adapting to changes in morphology. Bongard also addressed important questions about AI safety and AI ethics. Based on a recent publication on Machine Behaviour in Nature , he argued that we should treat machine behaviour in the same way as we treat animal behaviour, as something that evolves. Next Emma Borg (University of Reading) presented a paper on understanding agency in other people and in ourselves. She started comparing two accounts of how we explain and predict the agency of others, behaviour-re...

The 43rd annual meeting of the Society for Philosophy and Psychology  was held in Baltimore, Maryland, at Johns Hopkins University from 28-1 July, 2017. The meeting brought together philosophers, psychologists, and cognitive scientists working on issues of common interests. In this post, Federico Bongiorno (PhD student at the University of Birmingham) offers a summary of each of the keynote lectures presented in plenary sessions. On day 1, Daniel Schacter (Harvard) kicked off the conference with a talk on memory distortions and constructive aspects of remembering. Schacter views human memory as being far more a matter of constructive rather than reproductive processes that are sometimes susceptible to error and distortion. Two major themes were pursued. One is the idea that some types of memory distortions are side-effects of otherwise adaptive memory processes. The other is the critical role played by episodic memory, which is defined as the ability to recoll...

This post is by Miguel A. Vadillo  (pictured above), Lecturer in Decision Theory at King's College London. In this post he writes about cognitive biases, error management theory, and the reproducibility of research findings.  The human mind is the end product of hundreds of thousands of years of relentless natural selection. You would expect that such an exquisite piece of software should be capable of representing reality in an accurate and objective manner. Yet decades of research in cognitive science show that we fall prey to all sorts of cognitive biases and that we systematically distort the information we receive. Is this the best evolution can achieve? A moment’s thought reveals that the final goal of evolution is not to develop organisms with exceptionally accurate representations of the environment, but to design organisms good at surviving and reproducing. And survival is not necessarily about being rational, accurate, or precise. The target goal is actually t...

The Annual Conference of the British Society for the Philosophy of Science was held at the University of Cardiff Business School (pictured below), on 7th and 8th July 2016. The conference featured four keynote lectures and several papers in parallel sessions. Here I am briefly reporting from the two keynote lectures delivered on the second day of the conference. Samir Okasha (University of Bristol), pictured below, discussed in his keynote lecture the use of intentional language in describing the work of evolution. For instance, sometimes we say that the gene “knows” that it was inherited, or that an organism has a preference for a certain outcome to be selected. How should we understand the use of intentional language in this context? Is the intentionality of the language of biology something we can dispense with if we choose to, is it just a shorthand? Samir argues that it is more than a shorthand and delivers insights into evolution. Darwinian evolution is described in ter...
