When we read or if we fail to solve a riddle that we feel in control, says Tom Stafford, cognitive scientist. A new experiment shows, however, that the processes taking place independently of conscious thought may be larger than previously thought.
Psychologists agree that there is a subconscious that has a very important role in any process of thought. If you ask which is the capital of France, Paris you immediately comes to mind. If you move your toes, the process was not consciously prepared in advance. This was provided by the unconscious.
The big question is what the world of psychology made unconscious and requires conscious thought. A popular theory says that the unconscious is responsible for the actions of simple stimulus-response, the retention of basic things for object recognition and execution of learned movements. Cognition complex one involving planning, logical reasoning and combining ideas is a process of conscious thought.
A recent experiment by researchers from Israel shows that things are not quite so. Ran Hassin and his colleagues used a visual trick called "continuous flash suppression" to "plant" some information in mind volunteers without them being aware of them.
The technique uses the fact that we have two eyes and the brain tries to merge the two images received in a single coherent vision of the world. Continuous flash suppression uses some special glasses to show different images to each eye subjects. One eye sees a rapid succession of colored squares tawdry distracting so much that when the other eye receives Information authentic person is not immediately aware of that. In reality, it takes a few seconds until something is, in theory, perfectly visible, be aware.
Hassin's experiment involved the presentation of arithmetic problems unconsciously. were questions like "9-3 - n 4 =" and were followed by the presentation of a number clearly visible on the participants read it aloud. The number was either correct answer to the problem of arithmetic, or another number that had nothing to do with it. Results show that participants had a significantly better response time if the number had to be read correctly answer the problem of arithmetic, unless it was chosen at random.
This shows that the equation has been processed and resolved in their minds, even if they were not aware of the problem. Therefore, they were more likely to read the correct number faster.
The results suggest that the unconscious mind is more sophisticated capabilities than previously thought. Unlike other similar studies, it has not tested automatic response to a stimulus, but a concrete answer to which could be reached only following the rules of arithmetic, something that can be said to require a degree of deliberation.
The authors say that the technique used "change everything we know about the study of the unconscious", arguing that "unconscious processes can perform any basic function that can execute a conscious process".
