PhD studentships and vacancies
Postdoctoral Research Fellow
We have don't have any postdoctoral positions available at the moment. However, members of the group are also always willing to discuss potential fellowship/grant applications. Please contact one of the principal investigators if you are interested in applying for funding.
School of Psychology studentships
Every year the School of Psychology fund a number of studentships in a variety of areas in psychology, including Visual Neuroscience (for further info see this page on phd studentships in psychology).
Our group has at it's disposal facilities for a wide range of techniques for vision research (fMRI, EEG, TMS, psychophysics, computational modelling) and has interests in a variety of topics (e.g. selective detection of Fourier conjunctions, audio-visual integration). It also maintains strong collaborative links with the MRC Institute of Hearing Research, the Magnetic Resonance Centre and a number of additional departments outside Nottingham, including Bradford, Montreal, New York and Perth.
If you have your own ideas for a project in vision, please contact one of the principle investigators. The following represent some project ideas of our own for which we would especially like to see good candidates:
- How is texture-defined motion detected by the visual system? [uses: psychophysics/computer models/TMS; contact Tim Ledgeway]. Moving objects typically differ from their surroundings in terms of their textural properties (e.g. surface markings), but how these cues are extracted by the visual system to encode movement is still little understood
- How are the direction and speed of global object motion encoded? [uses: psychophysics/computer models/TMS; contact Tim Ledgeway or Ben Webb]. We know a great deal about how the visual system extracts velocity information from individual (localised) edges in the visual world, but rather little about how that information is subsequently combined to reveal the overall movement of complex objects
- Detection of spatially-extensive image contours and shapes [uses: psychophysics/computer models; contact Tim Ledgeway]. How the visual system is able to detect the outlines/boundaries of arbitrary spatial objects in cluttered visual scenes, by linking local measurements of edge orientation is an unresolved issue.
- The computational principles mediating visually guided decisions [method: psychophysics, computational modelling; contact: Ben Webb]. This project will examine how visual information is integrated over space and time in order to make perceptual decisions and issue motor commands.
- Does perceptual learning ameliorate the visual deficits in amblyopia? [method: psychophysics, computational modelling; contact: Ben Webb]. This project will examine the effects of perceptual training on the visual performance of the adult and juvenile amblyopic visual system.
- How groups of edges are detected by the visual system [uses: psychophysics/fMRI/computer models; contact Jonathan Peirce]. We know a great deal about how the visual system extracts information about individual edges in the visual scene, but rather little about how that information is used and combined.
- Impairments to dorsal stream processing in the brain [uses: psychophysics/EEG/computer models; contact Tim Ledgeway]. The dorsal pathway in the brain projects from primary visual cortex to the parietal lobes and is often referred to as the “where” pathway, as it is involved in motion processing, spatial cognition and visual motor planning. The ventral pathway projects from visual cortex to the temporal lobes and has been termed the “what” pathway, as it is involved in shape perception, visual memory and recognition of familiar objects/faces. Impairments to dorsal pathway functioning have been suggested as a defining characteristic of many developmental disorders, as well as healthy ageing. However the selectivity of this deficit is equivocal and its underlying nature is currently unknown.
