(Mis)Computation in Computational Psychiatry

Join us online!

Abstract

An adequate explication of miscomputation should do justice to the practices involved in the computational sciences. As elevant practices outside computer science have so far been overlooked, I begin to fill this gap by distinguishing different notions of miscomputation in computational psychiatry. I argue that a satisfactory explication ofmiscomputation in computational psychiatry should essentially appeal to semantic properties that characterise the interaction between a target computing system and its environment. Any account of physical computation that does not appeal to semantics for explicating miscomputation in psychiatric illness is inadequate.

Revisiting Binocular Rivalry

Join us online!

Abstract

Ask for the paper!

Hohwy et al.’s (2008) ‘epistemological’ explanation of binocular rivalry is taken as a classic illustration of predictive coding’s ubiquity and explanatory power. I revisit the account and show that it cannot explain a core feature of binocular rivalry, namely, perceptual dominance in rewarded conditions. A more recent version of Bayesian model averaging, known as Variational Bayes, can account for the role of reward in rivalry by recasting it as a form of optimism bias. However, I argue that if we accept this modified account, we must revise our understanding of perception as a neutral, informational or ‘theoretical’ process in the mind.

MEMORY and OPTOGENETIC INTERVENTION:
Separating the Engram from the Ecphory

Join the session

Ask for the paper

Abstract

Optogenetics makes possible the control of neural activity with light. In this paper, I explore how the development of this experimental tool has brought about methodological and theoretical advances in the neurobiological study of memory. I begin with Semon’s (1921) distinction between the engram and the ecphory, explaining how these concepts present a methodological challenge to investigating memory. Optogenetics provides a way to intervene into the engram without the ecphory that, in turn, opens up new means for testing theories of memory error. I focus on a series of experiments where optogenetics is used to study false memory and forgetting. I conclude with discussion of the recent discovery of “silent engrams” (e.g., Roy, Muralidhar, Smith, & Tonegawa, 2017) using optogenetics and the way in which these results create further opportunities and challenges for engram theory.

IIT VS RUSSELLIAN MONISM:
A Metaphysical Showdown on the Content of Experience

Join us online!

Ask for the paper!

Abstract

Integrated Information Theory (IIT) (Oizumi, et al., 2014; Tononi, et al., 2016) attempts to account for both the quantitative and the phenomenal aspects of consciousness, and in taking consciousness as fundamental and widespread it bears similarities to panpsychist Russellian monism (RM). In this paper I compare IIT’s and RM’s (in its categoricalist version) response to the conceivability argument, and their metaphysical account of conscious experience. I start by claiming that RM neutralizes the conceivability argument, but that by virtue of its commitment to categoricalism it doesn’t exclude fickle qualia scenarios (e.g. inverted or changing qualia). I argue that IIT’s core notion of intrinsic cause-effect power makes it incompatible with categoricalist versions of RM (Chalmers, 2013; Alter & Nagasawa, 2015) and, to the contrary, best understood as entailing pandispositionalism, the view for which all properties are powers. I show that, thus construed, IIT can cope with both the conceivability and with the fickle qualia arguments, offers a promising way to account for the content of experience, and hence is preferable to categoricalist RM.
