Picture superiority effect

The picture superiority effect refers to the phenomenon in which pictures and images are more likely to be remembered than words. This effect has been demonstrated in numerous experiments using different methods. It is based on the notion that "human memory is extremely sensitive to the symbolic modality of presentation of event information." Explanations for the picture superiority effect are not concrete and are still being debated, however an evolutionary explanation is that sight has a long history stretching back millions of years and was crucial to survival in the past, whereas reading is a relatively recent invention, and requires specific cognitive processes, such as decoding symbols and linking them to meaning.
