Departmental Seminar Series: Dr Renata Sadibolova
Please note that Renata's presentation will be the second of two presentations during this one-hour session...
Body misperceptions and delusions are known features of clinical conditions. Recent research, however, has begun to show that distorted body representations are surprisingly common also in healthy adults. I will present two experiments investigating the implicit and explicit representation of body shape and size in healthy adults. In the first experiment, the implicit 3D forearm was constructed from perceived distances between pairs of tactile stimuli on the skin and it was compared to the shape of actual forearm. Our findings highlight the combined role of visual and somatosensory representations in tactile distance judgements. In the second experiment, I recorded explicit estimates of 1D length and 3D volume of body parts. Body parts less exposed to the outer world, on account of their surface area being smaller relative to their overall volume, were more misjudged. These findings highlight the value of advancing understanding of body distortions in the general population with clear implications for the nature of perceptual distortions in clinical populations.
Renata joined Goldsmiths in October 2018 as a postdoctoral researcher to work with Devin Terhune on a project investigating the neural underpinnings of time perception. She previously completed her PhD, and was a postdoctoral research fellow, at Birkbeck, funded respectively by an ESRC studentship and a Birkbeck/Wellcome Trust ISSF fellowship. Renata’s research interests include body representation, somatoperception, and time perception, which she studies with a range of methods including psychophysics, machine learning, EEG, and fMRI.
