Visual encoding's role in memory is overestimated. We constantly take in and see stimuli, yet remember hardly any of it. Walking down the street one might see a hundred people's faces, yet none are encoded into memories. Thus visual encoding is not significant on its own but only matters as a tool to supplement other encodings. In addition, blind people cannot use visual encoding at all, yet can remember information just as well as someone with a working vision. Visual encoding is far from the most important encoding mechanism.
