We are seeking for an enthusiastic PhD candidate for our NWO-funded project on touch-color cross-modal correspondences in the visually impaired. You will be working in an interdisciplinary and international team (Dr Romke Rouw, Brain & Cognition, UvA; Prof. Dr Edward de Haan, Transdisciplinary Neuropsychology, Radboud University/UvA, Dr Nicholas Root, Post-doc, Brain & Cognition, UvA; Prof. Dr Darren Lipomi, Dept of NanoEngineering, University of California, San Diego). You will be working in the Psychology research institute at the University of Amsterdam in the Brain & Cognition group, where talented and internationally renowned scholars work on gaining a better understanding of the nature of human cognition and its neural basis. The Psychology institute has consistently high scores on international rankings, with top-tier facilities equipment and infrastructure, and a long history of commitment to post-doctoral education.
The projectIn this project, we examine
the
cross-modal 'translation' of visual features into tactile surface properties. We examine naturally occurring tactile-visual associations (e.g., "rough surfaces feel bluish-green") in both synesthetes and non-synesthetes. A unique collaboration with a nanoengineering lab will allow us to create bespoke haptic materials with precise variations along orthogonal physical dimensions, and explore their tactile (perceptual) responses. We thus systematically vary
physical material properties, to map out corresponding
tactile perception, which in turn may elicit
color-associations. This approach allows us to address fundamental questions about the mechanisms and brain structures involved in cross-sensory representations. In particular, are there innate mechanisms driving cross-modal associations, and what are the (cognitive and neurological) characteristics of touch-color associations? The project has societal implications; an open-access 'translator' from physical surface properties, to tactile experiences, to color associations. A proof-of-concept of the application of tactile representations of color images will be tested; tactile visual-art for the blind.
Please find here a hyperlink to the detailed project description. What are you going to do?In the PhD project, your task will be to study the behavioral and neural mechanisms involved in vision-to-touch cross-modal correspondences (CMCs) in blind participants.
Your project will address exciting research questions such as: To what degree are visual-to-tactile cross-modal correspondences comparable in blind individuals and in sighted individuals? Can we find evidence to support a neonatal hypothesis for cross-modal correspondences? How can we use obtained fundamental scientific knowledge to advise on a new means of sensory substitution: i.e., an application to employ different surface properties (tacky, wet, smooth) to convey colors?
You will/tasks: - complete and defend a PhD thesis within the official appointment duration of four years;
- gain knowledge of the field through literature survey, discussion with team members, and internal lab meetings;
- design and run behavioural and (functional & structural) neuroimaging experiments, in both sighted and visually impaired individuals;
- design and run in-depth single case studies;
- perform data-analyses, visualisation and dissemination of the experimental results;
- present data at local, national and international scientific meetings;
- perform the logistics of the project, (e.g., participant recruitment & scheduling, ethics approval, data-storage, etc.);
- assist in teaching (5% of your time), co-supervising junior scientists (MSc/BSc students).
