Effort during visual search and counting: insights from pupillometryGillian Porter
Department of Experimental Psychology, University of Bristol, Bristol, UK
Q J Exp Psychol (Hove) 60:211-29. 2007..In contrast, counting involves a heavy locational memory component from the start...
Dealing with illumination in visual scenes: effects of ageing and Alzheimer's diseaseGillian Porter
Department of Experimental Psychology, University of Bristol, Bristol, United Kingdom
PLoS ONE 7:e45104. 2012..This suggests that in AD, shadow-processing mechanisms, while preserved, might be applied in a less selective way...
What makes cast shadows hard to see?Gillian Porter
Department of Experimental Psychology, University of Bristol, Bristol, UK
J Vis 10:13.1-18. 2010..Findings are discussed in the context of the need for the visual system to distinguish between illumination and material...
Females, but not males, show greater pupillary response to direct- than deviated-gaze facesGillian Porter
Department of Experimental Psychology, University of Bristol, UK
Perception 35:1129-36. 2006..They also demonstrate that pupillary measurement can potentially provide new insights into the processing of even visual input, provided reflexes are sufficiently controlled...
New insights into feature and conjunction search: II. Evidence from Alzheimer's diseaseGillian Porter
Department of Experimental Psychology, University of Bristol, UK
Cortex 46:637-49. 2010..Moreover they demonstrate an additional processing mechanism in performing conjunction search compared with inefficient single-feature search...
New insights into feature and conjunction search: I. Evidence from pupil size, eye movements and ageingGillian Porter
Department of Experimental Psychology, University of Bristol, UK
Cortex 46:621-36. 2010..The data also highlight the independence of eye movement and pupillometry measures and stress the importance of saccades and strategy for understanding the processing mechanisms driving different types of visual search...
Intra-individual reaction time variability in amnestic mild cognitive impairment: a precursor to dementia?Andrea Tales
School of Experimental Psychology, Bristol University, Clifton, Bristol, UK
J Alzheimers Dis 32:457-66. 2012..The phasic alerting abnormality in aMCI compared to healthy aging does not appear specifically related to the performance of those patients for whom aMCI represents the prodromal stages of dementia...
Automatic change detection during the performance of a continuous visual taskAndrea Tales
Department of Experimental Psychology, University of Bristol, Clifton, Bristol BS8 1TU, UK
Neuroreport 20:1638-42. 2009..A significant vMMN was evoked. However, decreasing the rarity of deviation resulted in the abolition of the vMMN response...
Psychophysics reveals a right hemispheric contribution to body image distortions in women but not menChristine Mohr
Department of Experimental Psychology, University of Bristol, 12a Priory Road, Bristol BS8 1TU, UK
Neuropsychologia 45:2942-50. 2007..Moreover, the particular "fatter" bias after own body presentations to the left visual field in women supports the notion of a specific role of the right hemisphere in sex-specific body image distortion...
Exogenous phasic alerting and spatial orienting in mild cognitive impairment compared to healthy ageing: Study outcome is related to target responseAndrea Tales
Memory Disorders Clinic, The BRACE Centre, Blackberry Hill Hospital, Bristol BS16 2EW, UK
Cortex 47:180-90. 2011..Furthermore, these data provide further evidence in support of the existence of significant visual attention-related functional abnormalities in amnestic MCI...
Stimulus onsets and distraction in younger and older adultsGillian Porter
School of Experimental Psychology, University of Bristol, United Kingdom
Psychol Aging 27:1111-9. 2012..More generally, this study provides further evidence for the interaction, and nonadditivity, of stimulus-driven and goal-driven influences in determining processing priorities across the age span...
