Dear Users
This week (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
