I conduct research in human cognitive neuroscience using methods such as neuropsychology, fMRI, TMS and EEG.  The specific focus of my present research can be divided into three inter-related strands that all relate to individual differences in perceptual experience, and the relation between perception and other aspects of cognition (including memory and social cognition).

Synaesthesia and the multi-sensory brain

My research group is one of the world-leading centres for studying the phenomenon of synaesthesia (hearing flashes, tasting words, coloured music, etc.).  The research is revealing how individual differences in conscious perceptual experiences are linked to neurobiological differences and how they relate to cognition more broadly.  Our present research examines how synaesthesia is linked to memory function and perceptual sensitivity.

Social neuroscience of vicarious perception

My research in this area has focussed on how observing bodily states on other people (such as touch, pain and itch) interfaces with neural representations of our own body.  This includes atypical experiences (e.g. people who literally experience the pain of others) as well as more commonplace ones (e.g. the rubber hand illusion).  Understanding vicarious perception will provide novel insights in to the mechanisms of social cognition (e.g. empathy, perspective taking).

Sensory loss, sensory substitution and cross-modal plasticity

Normal neural pathways connecting the senses may become distorted or amplified by sensory loss (e.g. blindness) such that the ‘visual’ cortex responds to sound and touch.  One aspect of our current research examines the nature of this plasticity and how it reverses following restoration of sight.  Another aspect examines how technology (sensory substitution devices) can be used to represent the visual world via sound and touch to the visually impaired (see http://www.sussex.ac.uk/rmphillips/).  Finally, phantom sounds (in tinnitus) may be modulated by the somatic system in some people (e.g. moving their eyes or jaw affects the tinnitus) suggesting cross-modal plasticity of a somatic-auditory pathway in these individuals.
