Part 5: Escape

Change blindness and attention studies are of particular interest to Cognitive Neuroscience. Change blindness occurs when an observer, for any reason, fails to notice a change in a percieved event (usually an image). There are many ways this can happen and many brain systems involved in processing the information, and so nailing down the mechanisms of attention, say, as distinct from those of visual processing, understanding or conceptualizing, or assessing an event or image can be difficult. Using functional Magnetic Resonance Imaging (fMRI), we can percieve a near real-time image of brain activity as a subject notices or fails to notice a change, cutting away what else might be involved and isolating regions of activity involved with attention. That is, if we can notice what changes in the MRI images.
