"A new study has brought the estimate of how fast you can process an image down to an incredible 13 milliseconds.
The new study, conducted by MIT researchers and published in the journal Attention, Perception, and Psychophysics, used everyday images such as of picnics and smiling couples (Potter et al., 2013).
Previous research by Professor Mary Potter and colleagues had found it takes one-tenth of a second for images to be processed.
After hitting the retina, the information must be passed to the visual areas of the brain and then around processing loops to identify the image.
In the new study, they began presenting images to their participants faster and faster to see if they could still make accurate judgements about them."
