Shape representation of an object can be achieved by vision but also by haptics. There are many potential cues which can influence the processes of shape representation. In the PhD thesis, I present seven studies that provide new insights about the way in which haptics and vision perceive some specific spatial properties (mainly regularities) with the final goal of assessing potential cues each modality uses in order to better understand the main cues involved in the process of shape representation. The first study (Part 1, Chapter 2) showed that externalising the haptic input into a visual sketch during haptic exploration improved the recognition of raised line drawings, possibly by reducing the working memory load. The following four chapters (Part 2, Chapters 3-6) represent the core of the thesis. They investigated detection of regularities such as mirror-reflection symmetry and repetition. Despite the ubiquitous occurrence of these regularities in our environment, repetition is a spatial property which has never been investigated by haptics before.
