Synaesthesia - Exploring atypical perceptual and sensory experiences

Mary Jane Spiller has been working on a number of projects that explore the impact of long-term atypical perceptual/sensory experiences on cognition and individual differences. These include studies that explore the impact of synaesthesia on visuospatial abilities (in collaboration with researchers at the University of Edinburgh) and personality (in collaboration with researchers at the University of Sussex) in addition to exploring differences in the spatial cognition of individuals with visual impairment (in collaboration with researchers at the University of Bath). Mary was awarded a British Psychological Society Research Seminar Grant to run a series of seminars exploring Individual Differences in Multisensory Processing: Synaesthesia, Migraine, Sensory Impairment and Aging. These seminars were organised with researchers at the University of Essex and University of Bath. This seminar series resulted in a special issue of Multisensory Research. Mary is particularly interested in the possible relationship between mental imagery and synaesthesia.

The role of visual attention in object and face recognition

A long-standing project in Volker Thoma's research is the role of attention in object perception, and he found evidence that an object's recognition is mediated by a hybrid representation (view-dependent and part-based) depending on whether a seen object receives visual attention or not. Brain imaging data (with Dr Rik Henson) indicate that while view-based representation components are found in ventral and dorsal object processing streams, part-based representations (depending on attention) appear to be limited to ventral processing areas in the brain. Crucially, both behavioural and imaging data find evidence for processing of objects without attention. Recent collaborations are with Prof John Dylan Haynes (Humboldt University, Berlin) and Prof. Alan Richardson-Klavehn (University of Magdeburg).

Typical and atypical face processing

Prof. Volker Thoma, Dr Elley Wakui and Dr Davide Rivolta's (now at the University of Bari) work aims to characterise the cognitive and neural aspects of typical and atypical human face processing. Their research finds that face (and object) perception (but not memory) can be enhanced using non-invasive brain stimulation (tACS). Volker Thoma's research found that when perceptual load is high (e.g., many objects in a visual scene make it difficult to find an object, like your car in a full parking lot) then irrelevant information (e.g., a shopping trolley) is easy to ignore because your attentional capacity is used up by scanning many cars. Surprisingly, this is not the case for faces - it seems that face-capacity is category-specific - only if you look for a face among many faces will task-irrelevant faces be ignored.

Brain stimulation and physiological basis of judgment and decision-making

Prof. Thoma investigates the role of the frontal cortex in judgment and decision-making (JDM). One line of research investigates the role of brain stimulation in improving JDM in a healthy population and disordered gamblers. Other projects investigate the interplay between thinking dispositions and cognitive reflection abilities (e.g., in financial JDM).

Expertise, heuristics and risk perception in consumer psychology and user experience

Volker Thoma's work on consumer choice showed that the familiarity of products or objects is a major determinant of preferential choice even additional information about them was negative, a finding that was recently independently replicated. Volker also investigates risk perception and decision styles in experts, such as professional traders (previously funded by Eclipse Energy Partners), pension trustees (with City University and Leeds Business School) and non-experts. With Dr Paul Rodway (Chester) Volker investigates the role of heuristics such as the spatial location of products or the familiarity of brands using eye-tracking. A further line of work investigates thinking processes in human factors (online user experience and work organisation).

How does depression affect the brain?

At the present time, how we identify depression is based on what the individual is able to describe and show about how they are and what their family and friends describe about them. We do not have any biological measures that can tell us if someone has depression or another form of mental health disorder.

Cynthia Fu's research focuses on the brain regions affected by depression, how they may change with treatment with psychotherapy antidepressant medication or with talking therapy or pharmacotherapy, and whether we can predict clinical response outcome before the start of treatment.

We know that depression affects many regions in the brain involved in emotion processing, memory, cognition as well as motor functioning. We know that some regions are more commonly affected in depression and that some regions show similar impairments in other disorders.

From this work, Cynthia Fu has been looking at whether we can develop biological markers or 'biomarkers' to help us to say what kind of depression someone is experiencing and to predict clinical outcome. Her research has direct translational potential and had led to primary publications in the development of biomarkers for diagnosis and prognosis based on brain imaging.

Can neuromodulation treatment help depression and anxiety?

Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation. tDCS delivers a weak direct electric current which modulates neuronal resting membrane potential. tDCS affects how likely neurons will discharge but does not directly cause neurons to discharge.

Cynthia Fu is looking at whether tDCS could be a new first-line treatment for depression that can be given at home with research funding from the Rosetrees Trust.

Cynthia Fu and Elley Wakui are also looking at transcranial alternating current stimulation (tACS) as a potential treatment for anxiety as we know that mindfulness has been associated with brain oscillations in the alpha frequency.

Semantic effects during object and face naming

Experimental work has shown that when healthy adults retrieve object names, they take longer to name an object if they have earlier named an object from the same semantic category (e.g., vase, followed by jug). Melanie Vitkovitch has used experimental techniques to investigate the nature of types of semantic interference effects, analysing naming times and types of errors. These studies have also shown that naming a printed word can slow down related object naming, although in this case, the effect has not been found to be cumulative. She is also looking at semantic effects during face naming. In this more difficult task, it seems that the build-up of interference takes longer.

Understanding belief in the paranormal

Paranormal is a term used to describe events, phenomena, or abilities which lie beyond the scope of our current scientific understanding. Anna Stone's current research projects seek to understand how paranormal belief arises and is maintained, considering the question from a number of psychological viewpoints: social, developmental, and cognitive.

Recent publications include a new and wide-ranging questionnaire measure of paranormal belief and a book co-authored with Prof Chris French.

Attitudes to people with facial disfigurement

Facial disfigurement affects approximately one in 111 people, with causes including burns, scars, after-effects of surgery, congenital conditions, and birthmarks. People with facial disfigurement can experience negative reactions from the general public and are disadvantaged in education and in employment.

Anna Stone's current projects seek to understand the basis of negative assumptions about people with facial disfigurement and to investigate specific interventions that can help to combat prejudice and lead to equality and inclusion. If you are interested in taking part in research please contact

The interplay of overt attention and memory formation in healthy and pathological ageing

Dr Moreno Coco's current research focuses on neurodegenerative diseases such as Mild Cognitive Impairment (MCI) or Alzheimer Dementia (AD), and, on predicting their onset early enough to anticipate treatment to ameliorate their detrimental impact. People facing with neurodegenerative diseases often display dysfunctional memory processes. Despite evidence on young adults about the cognitive mechanisms involved in the formation of memory, research in healthy and pathological ageing on this important topic is still lagging. In particular, substantial research should be devoted to understanding: (a) the use of contextual information during short and long-term memory processes, (b) the impact that stimulus properties, behavioural and neural responses bear on substantiating such processes, as well as, use this knowledge to design novel diagnostic tools aimed at detecting the onset of neurodegenerative diseases yet in the prodromal stage. This work has received funding by the Leverhulme Trust and by the Fundação para a Ciência e a Tecnologia.

Pain perception and pain modulation

Matteo Martini's work focuses on the study of human pain perception and pain modulation in relation to the activation of other sensory channels. Visual, tactile or even visuo-vestibular cues are the possible 'pain modulators' considered in his studies. Experimentally-induced acute pain states are induced to study the possible analgesic effects of cross-modal stimulations, with the future aim to develop non-pharmacological treatments. In his lab, Dr  Martini and his coworkers induce pain via a thermode attached to a machine (a TSA 2 - Quantitative NeuroSensory Analyzer) which can deliver both cold and hot stimuli. Different stimulation paradigms can be taken into account and, along with the participants' responses, brain responses (for instance via EEG) can be recorded too. Different projects have been run so far, with or without the aid of virtual reality and 'virtual embodiment'.
