Text Processing in the Brain: Cognitive Pathways Explored

I recently found an article that claimed the human brain processes visuals 60,000 times faster than text and I thought wow thats fast. Then I thought hang on, is that true? Off I went in search of an answer...

There isn't a specific, universally accepted scientific measure quantifying how much faster the brain processes images compared to text. The processing of visuals versus text involves different cognitive functions and pathways in the brain, making a direct comparison complex. However, several pieces of research provide insights into how the brain processes these different types of information:

1. Visual Processing Speed: Visual information can be recognised and interpreted rapidly, typically within about 100 milliseconds after exposure to an image. This is due to the brain's highly efficient visual processing system, which evolved to quickly interpret visual stimuli essential for survival.
2. Reading and Cognitive Load: Reading involves decoding symbols (text) into sounds and meanings, which is a more sequential and time-consuming process. It requires not just recognising shapes of letters and words but also involves phonemic and semantic processing.
3. Dual Coding Theory: This theory suggests that text and images are processed in different cognitive channels—verbal and visual, respectively—which can operate independently but also interact. According to this theory, integrating text and visuals can lead to more effective communication because it engages multiple processing pathways.
4. Pictorial Superiority Effect: Research supports the idea that people tend to remember information better when it is presented with images rather than as text alone. This effect demonstrates the efficiency of visual memory but doesn't quantify processing speed as such.

While specific metrics like the "60,000 times faster" claim are not scientifically supported, it is clear that the brain does process visual information very efficiently, often faster than textual information, particularly in recognising basic elements and gist of the scene. However, the effectiveness of visuals versus text can depend significantly on the context and the type of information being conveyed.
