My PhD investigates if top-down processes are involved in the perception of three-dimensional (3D) shape. I am particularly interested as to whether top-down (guided) attention facilitates the perception of 3D shape created from shading cues. My work also seeks to investigate if different cognitive and neurological processes underlie the perception of convexity and concavity. To investigate these notions, I employ both behavioural (e.g., accuracy / response time) and neuroscientific (e.g., event-related potentials) methods.


This research is being conducted under the supervision of Dr Ayelet Sapir and Prof Debbie Mills.
