Objective:  Is the human mind a symbolic computational device? This issue was at the core Chomsky’s critique of Skinner in the 1960s, and motivated the debates regarding Parallel Distributed Processing models developed in the 1980s. The recent successes of “deep” networks make this issue topical for psychology and neuroscience, and it raises the question of whether symbols are needed for artificial intelligence more generally.

One of the innovations of the current project is to identify simple empirical phenomena that will serve a critical test-bed for both symbolic and non-symbolic neural networks. In order to make substantial progress on this issue a series of empirical and computational investigations are organised as follows. First, studies focus on tasks that, according to proponents of symbolic systems, require symbols for the sake of generalisation. Accordingly, if non-symbolic networks succeed, it would undermine one of the main motivations for symbolic systems. Second, studies focus on generalisation in tasks in which human performance is well characterised. Accordingly, the research will provide important constraints for theories of cognition across a range of domains, including vision, memory, and reasoning. Third, studies develop new learning algorithms designed to make symbolic systems biologically plausible. One of the reasons why symbolic networks are often dismissed is the claim that they are not as biologically plausible as non-symbolic models. This last ambition is the most high-risk but also potentially the most important: Introducing new computational principles may fundamentally advance our understanding of how the brain learns and computes, and furthermore, these principles may increase the computational powers of networks in ways that are important for engineering and artificial intelligence.

When and Why do Neural Networks Learn Selective Codes?
The Leverhulme Trust.  ~£250K

Abstract: This four-year project aims to understand why some neurons respond to information in a highly selective manner. It comprises a series of four computer simulation projects that characterize the representations learned by artificial neural networks across a range of conditions. The findings will demonstrate when and why selective codes are learned in artificial networks and provide insights into why and when neurons respond in this way. A better understanding of the computational advantages of selective coding is fundamental to understanding how the brain supports cognition and will have important implications for theories in psychology and neuroscience.

Improving Literacy Outcomes in Struggling Readers: A Randomised Control Study
The Nuffield Foundation, ~£200K

Abstract:  This project is a randomised control trial (RCT) to test the efficacy of a morphological training intervention called Structured Word Inquiry (Bowers & Kirby, 2010). This form of instruction makes use of graphical methods that highlight the logic and structure of English spelling, and capitalises on the benefits associated with structuring and organising learning material.

While there are many anecdotal reports of the efficacy of this method, there is little systematic evaluation. However, Structured Word Inquiry may be especially beneficial for children who are resistant to intensive phonics instruction (perhaps due to phonological deficits), because it takes a compensatory approach that focuses on training their stronger skills.
