Behavioural evidence for task-dependent, 'what' versus 'where' processing within and across modalities
CHAN, JASON; NEWELL, FIONA (The Psychonomic Society, 2008)Task-dependent information processing for the purpose of recognition or spatial perception is considered a principle common to all the main sensory modalities. Using a dual-task interference paradigm, we investigated the ... -
Combined structural and functional imaging reveals cortical deactivations in grapheme-colour synaesthesia.
NEWELL, FIONA (2013)Synaesthesia is a heritable condition in which particular stimuli generate specific and consistent sensory percepts or associations in another modality or processing stream. Functional neuroimaging studies have identified ... -
Crossmodal priming of unfamiliar faces supports early interactions between voices and faces in person perception
NEWELL, FIONA (2017)Although faces and voices are important sources of information for person recognition, it is unclear whether these cues interact at a late stage to act as complementary, unimodal sources for person perception or whether ... -
Distinctive voices enhance the visual recognition of unfamiliar faces
NEWELL, FIONA (2015)Several studies have provided evidence in favour of a norm-based representation of faces in memory. However, such models have hitherto failed to take account of how other person-relevant information affects face recognition ... -
Distinctive voices, not arbitrary sounds, enhance the visual recognition of faces
NEWELL, FIONA; NEWELL, FIONA (2015)Several studies have provided evidence in favour of a norm-based representation of faces in memory. However, such models have hitherto failed to take account of how other person-relevant information affects face recognition ... -
The effect of non-informative spatial sounds on haptic scene recognition
NEWELL, FIONA (2013)Previous studies found that performance in tactile or haptic spatial tasks improved when non-informative visual information was available, suggesting that vision provides a precise spatial frame to which tactile information ... -
The effect of the neurogranin schizophrenia risk variant rs12807809 on brain structure and function.
MORRIS, DEREK; MC GRATH, JANE; ROBERTSON, IAN H; NEWELL, FIONA; O'DOHERTY, JOHN PHILIP; GILL, MICHAEL; TROPEA, DANIELA; DONOHOE, GARY (JAMES); CORVIN, AIDEN PETER; GARAVAN, HUGH PATRICK; BOKDE, ARUN LAWRENCE WARREN (2012)A single nucleotide polymorphism rs12807809 located upstream of the neurogranin (NRGN) gene has been identified as a risk variant for schizophrenia in recent genome-wide association studies. To date, there has been little ... -
Individual differences in context-dependent effects reveal common mechanisms underlying the direction aftereffect and direction repulsion
NEWELL, FIONA (2016)Both spatial and temporal context influence our perception of visual stimuli. For instance, both nearby moving stimuli and recently viewed motion can lead to biases in the perceived direction of a moving stimulus. Due to ... -
Menstrual cycle phase modulates cognitive control over male but not female stimuli
GARAVAN, HUGH; NEWELL, FIONA (2008)Evolutionary selection pressures have been one of the factors proposed to underlie sex differences in inhibitory control. Consequently, inhibitory control may vary as a function of the menstrual cycle and may be modulated ... -
Multisensory processing in review: From physiology to behaviour
NEWELL, FIONA (Brill Academic, 2010)Research in multisensory processes has exploded over the last decade. Tremendous advances have been made in a variety of fields from single-unit neural recordings and functional brain imaging through to behaviour, perception ... -
Neuromorphic vibrotactile stimulation of fingertips for encoding object stiffness in telepresence sensory substitution and augmentation applications
NEWELL, FIONA (2018)We present a tactile telepresence system for real-time transmission of information about object stiffness to the human fingertips. Experimental tests were performed across two laboratories (Italy and Ireland). In the ... -
Perceptual and social attributes underlining age-related preferences for faces
NEWELL, FIONA (2016)Although aesthetic preferences are known to be important in person perception and can play a significant role in everyday social decisions, the effect of the age of the observer on aesthetic preferences for faces of different ... -
Perceptual learning shapes multisensory causal inference via two distinct mechanisms
NEWELL, FIONA (2016) -
The sound-induced flash illusion reveals dissociable age-related effects in multisensory integration.
NEWELL, FIONA (2014)While aging can lead to significant declines in perceptual and cognitive function, the effects of age on multisensory integration, the process in which the brain combines information across the senses, are less clear. ... -
Susceptibility to a multisensory speech illusion in older persons is driven by perceptual processes.
NEWELL, FIONA (2013)Recent studies suggest that multisensory integration is enhanced in older adults but it is not known whether this enhancement is solely driven by perceptual processes or affected by cognitive processes. Using the “McGurk ... -
The Virtual Haptic Display: A device for exploring 2-D virtual shapes in the tactile modality
CHAN, JASON; NEWELL, FIONA (Psychonomic Society, 2007)In order to understand better the processes involved in the perception of shape through touch, some element of control is required over the nature of the shape presented to the hand and the presentation timing. To that ...
