- Abstract
- The duality of vision refers to the idea that perception and action rely on the ventral and dorsal streams, respectively, because they apply specific constraints to the processing of the visual input. However, the existing evidence in favour of the duality of vision is corrupted by the additional sensory information that action execution benefits from compared to perception. This thesis aims to investigate the representations and processes underlying perception and action by using prospective judgments about one’s capability to perform an action. These judgments give access to the neurocognitive processes involved in grasping while avoiding the artefacts caused by the execution of hand movements. I collected behavioural and neuroimaging data showing that, regarding the processing of size, perception and action are not tied to specific transformations of the visual input and do both require the collaboration of the ventral and dorsal streams.
