![]() "The use of single case studies in synesthesia is also of concern because the results obtained with one synesthete may not generalize to other synesthetes. Importantly, the researchers found evidence suggesting that synesthetes may be quite different from one another, which the researchers said "has profound implications for the studies of synesthesia that group together data from multiple synesthetes and treat them as if they all come from a homogeneous population. In fMRI, harmless radio waves and magnetic fields are used to map regions of higher blood flow in the brain, which reflects higher activity in those regions. The researchers found that the strength of this activation influences the strength of the synesthetic colors. In fMRI scans, the researchers found that the synesthetes showed greater activation in a color-perception region of the cortex when viewing graphemes, compared to normal control subjects. However, the experiments with both the synesthetes and the controls also revealed that the synesthetic colors were not as effective as real colors in such tasks. ![]() The researchers found that the synesthetic colors really did help the synesthetes distinguish the shapes or graphemes, compared to normal control subjects who were tested on the same patterns. In another experiment, the researchers found that synesthetic color helped the synesthetes pick out specific numbers or letters in a crowded display. They designed the experiment so that if the synesthetes really were seeing the colors, that color perception would help them distinguish shapes such as triangles or squares formed by the graphemes. They chose those graphemes that the synesthetes reported elicited specific colors. In one such experiment, they presented six synesthetes with patterns of black letters or numbers-known as "graphemes"-on a white background. In their experiments with synesthetes who report seeing colors when they view numbers or letters, the researchers first sought to determine whether synesthetes really see the colors. Now, however, researchers such as Hubbard and his colleagues are using the condition to gain insights into the neural basis of perception. The rare condition called synesthesia-in which people's sensory perceptual circuitry seems to be miswired-was long dismissed as an oddity not worthy of scientific study. This cross-activation might develop, they theorize, by a failure of the "pruning" of neural connections between the areas in the developing brain. ![]() Some synesthetes report seeing colors when listening to music, or feeling tactile shapes while tasting food. Wow, that was longer than i thought it would be.The researchers said their findings lend support to the hypothesis that the condition is due to cross-activation between adjacent brain areas involved in perceiving shapes and colors. mostly the positions make sense, but sometimes they don’t.) (idk why it’s so far away from the other tragedies. king lear is also difficult-it could be anywhere on the line from around richard ii to around as you like it. merry wives is kind of difficult to place-it’s simultaneously next to henry iv pt 2, and somewhere around where king john or titus andronicus is. however, the henriad was easy to place, and the positions of those four plays on the diagram are very similar to how they are in my head. for example, in the two “clumps” of plays i don’t know that well-those plays were difficult to place because they don’t quite have fixed positions for me. the better i know a play, the more fixed its position becomes. It’s also not fixed-as i become more familiar with different plays, it changes shape somewhat. whenever i’m thinking about shakespeare plays, this visual will automatically appear in my head, and i can manipulate it and “travel” around it at will. So i made a diagram thing- what is it? an arbitrary grouping of shakespeare plays? nope, it’s actually a synesthesia thing called spatial sequence! that basically means that sequences (numbers, time, the year, the alphabet, seasons of star trek, etc) are all arranged in a very particular way in my head. I am definitely planning to conduct more surveys in the and you might be interested in this. The pages include graphs, the sample sizes for each survey, a link to download the raw data, and my commentary on the results.Īlso, if anyone is interested, I am currently conducting a survey about spatial sequence synesthesia-specifically, year-form: Links to all the results of all my surveys so far can be found here: If any professional synesthesia researchers see this-an interesting experiment would be to follow up on these surveys using more scientifically sound techniques. All surveys were non-professional, but they yielded some fascinating results. ![]() I conducted surveys about grapheme-color, ordinal-linguistic personification, weekday-color, and month-color. I have finally finished analyzing the results of the synesthesia surveys that I conducted! ![]()
