It has long been taken for granted that consciousness is required to complete such tasks. While scientists have shown that people can do simple things like add 2+2 and process single words without realizing it, researchers have generally believed that anything more complicated than that would require our conscious attention. Myriad experimental techniques exist to disrupt conscious perception for a brief time including what's called "masking," in which a visual image is presented directly after a target, leading to an inability to consciously perceive the target. For example, if the number five were presented directly before a mask, you would never know you saw the five, even though you may have perceived it unconsciously. Many studies have shown that masked stimuli can still impact decision making and response times, which is how we know they can be perceived at all. Here's an example: In one study, subjects were shown a number and asked to determine whether or not it was a prime number.
which they did not consciously perceive. Nonetheless, if the number they were evaluating for "primeness" was the same as the answer to the masked math problem, they were much faster at telling whether it was prime. This shows that, at some level, the subject's brain solved the problem. The same has been shown to be true for the perception of single words. But what about more complex math problems, or even multi word English phrases? Puma Creepers Velvet Red How far c.
