Although usually defined as a learning disorder that is specific to reading, dyslexia reflects natural variations in neurological processing of the visual form of words and their associated sounds. Recent advances in neuroscience show that in learning to read we ‘reuse’ parts of the brain that are initially involved in face and object recognition.

The starting point for our research in this area is the observation that recognition of words and faces present similar challenges to the visual system. Both are made up of parts, features (eyes, nose and mouth) in the case of faces and individual letters in the case of words. Spatial configuration - the specific way in which these parts are arranged – is very important to recognizing individual faces and individual words. Our first study borrows two well-known experimental paradigms from face perception research to study word recognition and shows clear differences in how dyslexic and typical readers utilize configural information (Conway et al., 2017). More recently, and working with Dr Sarah Cooney (UCD) and Professor Fiona Newell (TCD), we show that holistic processing in a faces task predicts differences in reading performance (word and pseudoword accuracy and speed) between dyslexic and typical readers. This research suggests that the factors underlying ‘dyslexia’ are multifactorial, and that broadening our thinking about reading may help de-emphasise dyslexia as a ‘disability’ while furthering our ability to support students for whom reading is challenging.

The way we process sensory information influences the enrichment we receive from our environments. This has consequences for plasticity processes that impact brain health. Correspondingly, deficits in sensory processing can be observed across a multitude of conditions impacting neurocognitive health including dyslexia, ADHD, depression, Alzheimer’s disease, and stroke.

Our research aims to understand how inter-individual differences in brain structure and function impact sensory processing. The overarching goal of this work is to inform interventions that can increase resilience to neurocognitive deficits in clinical conditions, especially those occurring with advancing age.

How do we pack a suitcase, fill the dishwasher, or find our way around a new city? These tasks all rely on spatial thinking, the cognitive ability to manipulate shapes and space. Not only is spatial cognition fundamental to independent living, but there is now convincing research that spatial cognition plays a role in Science, Technology, Engineering and Mathematics (STEM) achievement. This leads to the exciting question as to whether spatial cognition can be manipulated to improve educational outcomes in STEM. My research explores this question from different perspectives, using different methodological techniques. Current research on this topic includes: 1) An investigation of whether spatial training using Lego can be used to improve mathematics skills in childhood (collaboration with Prof. Emily Farran, University of Surrey and Prof. Camilla Gilmore, University of Loughborough); 2) A review of previous evidence on the associations between spatial skills and science performance (collaboration with Dr Zack Hawes, University of Toronto, Dr Emily Petterson, American University in Washington and Dr. Kinnari Atit, University of California; and 3) An evaluation of how teachers use our Spatial Reasoning Toolkit to embed spatial practices into their teaching (collaboration with the Early Childhood Maths Group https://earlymaths.org/spatial-reasoning/)

The COVID-19 outbreak has been accompanied by a wave of misinformation whose impact has been increased by isolation, and many people’s subsequent reliance on social media as a source of news. This has significant implications for health behaviours and compliance with public health guidance. Building on our previous work investigating the drivers of misinformation acceptance, this project aims to establish (1) the factors affecting an individual’s response to misinformation about COVID-19, and (2) the effectiveness of a range of cognitive interventions aimed at reducing the spread of COVID-19-related misinformation. Understanding why people believe in, share or act on misinformation is critical to slowing its spread. The interventions developed in this project will give people the tools to evaluate information and become more critical consumers of news media. In doing so, we hope to empower citizens to protect themselves and their families from public health threats.

How do we perceive our own and other peoples bodies? How does multisensory information ( e.g., vision, touch, interoception and proprioception) give rise to body perception? This project looks at cases where people experience anomalous multisensory perception — such as those with mirror touch synaesthesia — and cases where body perception is disrupted, such as Anorexia. Body image disorders are associated with a host of cognitive, affective, and perceptual issues. Using a mixed-method approach, work in the lab utilizes large scale online data collection and Virtual Reality to study the relationships between the complex and multifaceted characteristics of body perception. Forthcoming studies in this project investigate recent neuroscientific models of body perception in individuals with body image disturbances and explore the translational potential of VR within clinical health interventions.

To study, diagnose and treat disease and disorders that impact neuropsychological function, researchers and health professionals rely heavily on standardised assessments. While reliable and relatively easy to administer, traditional standardised assessments have been criticised for their lack of ecological validity. Assessment of social cognition (our ability to process social information) is particularly susceptible to this problem. Social cognition processes are incredibly sensitive to the rich and complex dynamics of naturalistic social interactions. Assessment of this capacity requires meaningful and emotionally laden stimuli with precise and nuanced measurement. Media entertainment experiences lend themselves well to the requirements of experimental control, yet they are designed specifically to move emotion and capture attention, using meaningful social interactions. This project explores the ways in which social cognition responses are shaped by media design features, with a view to validating their use in neuropsychological assessment.

In our daily interactions with others, we may subconsciously copy their postures and facial expressions or quite literally feel their pain when they hurt themselves. These mimicry and mirroring processes seem to be rooted in basic mechanisms that we share with other species. In contrast, some of our higher-level social abilities appear to be uniquely human. The latter usually involve imagining how another person experiences the world from their perspective and what they believe about the world to be true. In other words, we are capable of generating an explicit “theory of (another’s) mind”.

First, our research aimed at investigating how humans mentally “put themselves into someone else’s shoes”. Interestingly, we observed that humans mentally simulate a rotation of their body into another’s orientation to understand how the world appears from that perspective (Kessler & Thomson, 2010). Thus, humans seem to deliberately repurpose their body-control and -monitoring systems to solve high-level socio-cognitive tasks, which is often referred to as “embodied processing”. More recently, our research investigated the underlying cortical network, revealing important processing hubs and oscillatory rhythms that link the network together (e.g. Wang et al., 2016; Seymour et al., 2018). With the facilities afforded by the new Mental (Neuro-) Chronometry lab in the School, we are currently investigating these oscillatory brain networks in detail, aiming to understand and differentiate between various facets of Theory of Mind, such as perspective vs. belief processing (e.g. Green et al., 2023).

Previous work has demonstrated that the processing of action-related language leads to modulation of activity in the motor system. This supports the idea that our representation of language is not entirely amodal and involves our sensori-motor systems. Weaknesses in previous work, however, include a narrow range of language stimuli (mainly verbs) and a failure to address factors such as the depth of processing involved in a given task, and the age of acquisition of the stimuli employed. This project aims to widen the categories of stimuli used and to vary the level of processing required as well as controlling for age of acquisition. The work measures excitability of the motor system through reaction time data.

Our projects include undergraduate, master and PhD students at the UCD Psychology, UCD Neuropsychology Lab, respecting ethical and open science principles. In the UCD Music and Math Cognition, we are studying the mechanisms by which numerical cognition interacts with spatial skills using EEG and Eye-Tracking. We are developing with Dr Pierpaolo Dondio (Technological University Dublin, Ireland) digital games to improve mathematics learning and reduce mathematics anxiety in children. We are collaborating in a Multi-Site study regarding Statistics Anxiety with Jenny Terry and Professor Field (University of Sussex, UK) and Angelica Trassi (UNESP, Sao Paulo State University, Brazil). We are also investigating how feelings about mathematics influences career choice in undergraduate students, which is another international collaboration with Krzysztof Cipora (Loughborough University, UK) and Sara Caviola (University of Padua, Italy). Concerning Music Science, we are interested in how musicians experience and cope with emotions pre-concerts. Another study explores specifically whether consumers will be more likely to choose seasonal clothes after listening to seasonal music.
