Dear Users
Today (4-5 pm YNiC open plan) Chris Racey will give a project proposal talk on "Processing of real world objects in object selective cortex: effects of parametric manipulation of size change".
Summary: The visual system is able to perform recognition tasks in a manner that appears to be invariant to changes in size of the retinal image. It is thought that this size invariance is established early on in visual processing (Goodale & Milner, 1992; Rolls, 2000). The aim of the present study is to measure adaptation to objects of changing size across the whole visual system and across several size change conditions which vary parametrically. The design of the present experiment will be an fMR-adaptation paradigm similar to that used in our previous work looking at viewpoint invariance (Racey et al., 2010). We aim to measure differences in size invariance for objects between the various category selective brain regions at the level of the Ventral Occipito-Temporal cortex (VOT). Further, we aim to measure the change in size invariance moving posterior to anterior through the visual processing hierarchy.
Everyone is welcome to attend.
Best wishes Rebecca
