Nice post and interesting results, you said,
I agree, as an adaptation we could try using powerpoint, create slides with words, with timed unmasking of words and sequences of letters using different widths and time between letters, (this would ensure consistency and repeatability to the test). This is the long hard way to do things but is the most flexible.
Or use an online color-grapheme test if one is available (which may not be as flexible as we would like, a tradeoff). There are (at least) two more variables to consider, one, eye tracking
, after reading the article in full I realize that there are many things to consider, the most important was the way the eyes process move to distinguish and then process data, through fixation and saccade
In addition if you look at this figure: see attached thumbnail: you will see the fixation times vary, for instance in the fourth line down, after "syd-" the eye slowed
to analyze the hypen and space after it. Interesting...
The second issue
is environment you test in, preferably a comfortable place with few distractions.
You also said,
that is interesting because for you red is your most predominant color, maybe it is "most quickly primed in your visual cortex", you said it was "quite distinct".
A lot to consider and I think you will agree not an easy thing to do after taking a peek a "bit deeper under the covers", I for one appreciate a more detailed understanding of how we visually acquire and process information, which can't be a bad thing, right ? hehe.
All of what follows is my on-line search for a test close to the one we have in mind. A scary thought just came over me, what if no one has ever done this test before, hmmm.
I found this pdf doc
by Dr Cytowic including results from: "A new measure: the speeded congruency test" but this was only for recognizing individual letters. You may find this interesting because it shows with 1 to 2 ms accuracy how synesthetes differentiate individual letters on various levels of shaded backgrounds.
You may find this interesting as well: Grapheme-Color Synesthesia Mapper
where all people reading this thread can take the test and then record for posterity their personal maps !
There are about two dozen or so there right now. I found it interesting, (assuming of course that most of the testers did not lie cheat) that there were some "fragmentary associations". This is consistent with waht experience for sound -> color, only certain frequency ranges played a specific way for a specific duration cause the sensation.
I also found this: The Synesthesia Battery
From a quick scan of it, it doesn't seem to have the test we are trying to accomplish.
I can't say for certain, but after a substantial time of not finding a similar test, then it's back to doing it the hard way. What do you think, RasalHague, should I play with Powerpoint to see if I can come up with automated timed slides ? Do you have any creative ideas ? I am open to them, or from anyone else following this thread ?
P.S. I will be away for the next two days without computer access so, please don't get the wrong impression, I will check back in on Sunday evening. Thanks...
