I am interested in the mental representations underlying human memory and perception. What is the role of the hippocampus in memory? How does the brain carve experience into distinct "events"? How do individual differences in memory and perception relate to different networks in the brain? Finally, how are these brain circuits affected in ageing, dementia, and neurological disease?


Undergraduate education

I was awarded my undergraduate degree (BSc Psychology) from Cardiff University in 2006. During this period, I worked as a research assistant with Professor Ulrike Hahn where I programmed and developed cognitive tasks for studying similarity and categorisation.

Postgraduate education

Following on from my undergraduate experience, I was awarded an EU-funded studentship to undertake a PhD in Cognitive Science at Cardiff University. During this time, I worked with Ulrike Hahn and Nick Chater, exploring the relationship between similarity, categorisation and object representation (Hodgetts, Hahn & Chater, 2009; Hodgetts & Hahn, 2012).

Research topics and related papers

Current project

Currently, I am working on a project investigating the memory and perception of young, healthy individuals who possess a genetic risk factor for  Alzheimer’s disease (AD). Previous research suggests an overlap between the brain regions implicated early on in AD and those active during spatial processing in healthy participants. As individuals with AD also show impairments on spatial/scene memory, this research investigates whether those individuals at genetic risk show differential activation in those regions that have been marked in both spatial memory and early on in AD.

Similarity and conceptual knowledge

Another aspect of my research focuses on what makes things similar. Specifically, I am investigating a new theory of similarity based on the number of transformations between object representations. Transformations are an important part of our visual and conceptual experience; objects and scenes transform continuously as we move about the world, organisms transform in principled ways, and man-made artefacts deteriorate over time. Our goal is to understand how transformational relationships, through their real-world prevalence, serve important cognitive and conceptual functions.
