Attention and eye movements

We are constantly bombarded with a vast array of dynamic perceptual input. The majority of this input is generated by our own actions, however. For example, each time the eyes move, which they do many times each second, neurons throughout the visual brain begin receiving information from a new location in space. This represents an enormous change in the visual array, but has a surprisingly small effect on perception. This studentship is part of a larger project exploring the role of attention in perceiving the sensory consequences of eye movements and other actions with the goal of understanding how we perceive and differentiate self-generated and externally-generated sensory input. The specific question explored in this project is how we detect and correct errors in the execution of eye movements and other actions.
