Накратко на български

Механизмите на сетивното обучение се изследват чрез разпознаването на лица в изправено и обърнато положение. Това помага да се разбере как опитът подобрява възприятието ни и как мозъчната стимулация може да контролира тези процеси.

Perceptual Learning

Even though perceptual learning is well established as a phenomenon, and we have some idea how it works, we do not know a great deal about the mechanisms involved or how to modulate them. The results from this project help us to understand the mechanisms controlling perceptual learning and give us some insights into: 1) The neural structures and processes that allow us to benefit from experience and improve discrimination. 2) How to control and modulate these processes using brain stimulation techniques. 3) A better understanding of perceptual learning’s role in face recognition skills. The main findings from the project provide evidence in support of a specific experimental brain stimulation method, that allows us to selectively modulate perceptual learning indexed by a robust cognitive phenomenon known as the inversion effect (better recognition performance for upright vs inverted stimuli). We have shown that a brief brain stimulation manipulation can either decrease or increase the inversion effect by reducing or enhancing recognition performance for upright stimuli. Furthermore, these brain stimulation-induced effects have their electrophysiological correlates on a specific event-related potential (ERP) component. Importantly, we also found how certain brain structures are more activated in response to brain stimulation while participants perform a perceptual learning task.

Цел на проекта

Perceptual learning is fundamental to human cognition. It can be defined as an enhancement in the ability to distinguishbetween similar stimuli (that otherwise would be very hard to tell apart) as a consequence of experience with them, or withstimuli similar to the target stimuli. This allows the wine connoisseur to distinguish between different wines, the birdwatcher to tell one warbler from another, and people to identify that face as a given person rather than someone else, if theface is taken from an ethnic grouping that they are familiar with. My research focuses on the mechanisms responsible forperceptual learning. By using a range of neuroscience techniques (tDCS, fMRI, TMS/MEP, EEG/ERP) in conjunction withthe behavioural designs provided by experimental psychology I will investigate the neural basis for perceptual learning, test acomputational model of the phenomenon, and try to control the development and expression of this perceptual skill. Thisprogramme of research will train me in new techniques, further develop my expertise in the domain of perceptual learning,and allow me to work in one of the leading laboratories for this type of research at the present time. It will also allow me toraise my and my discipline's profile, and to do this, as part of this research proposal, I will convene an InternationalWorkshop on Perceptual Learning to bring together the various researchers working on this issue and publish theproceedings as an edited book.
