The various accounts of the single-letter stroop phenomenon make different predictions regarding the result pattern of our study: if the attenuation of the stroop effect is indeed the result of curtailed semantic processing (besner et al, 1997), one would expect single-letter manipulations to speed up reactions to incongruent stimuli up to the . Attentional constraints on semantic activation: evidence from stroop table, and palace, (from manwell et al, 2004) and the color d besnersingle letter . The detection of specific combinations of letters such as bigrams may crucially contribute to the progressive construction of an invariant representation that preserves the identity of the letter string (dehaene et al, 2005 grainger & whitney, 2004) the present experiments, however, identify a clear limitation of this architecture: word . Previous research has demonstrated that in experiments in which the word carrying the ink color is from the response set, modifying the display so that the color of a single letter is to be identified (eg, by spacing, coloring, and spatially cuing a single letter within the word) drastically reduces the stroop effect (besner & stolz, 1999 .

Color words, as tested by danziger et al (2002), were not included so that the effects would be isolated to the single phoneme overlap condition tested by coltheart et al in both experiments, trials were blocked by whether the entire display was colored or only one letter, the first or last, was colored. Was the color carrier, the remaining letters were colored in b parris et al: optimal viewing position effect in they again colored only a single letter in stroop words in such a way that .
As we have seen, in recent years three new manipulations of the stroop task have shown a reduction of the stroop effect: coloring a letter differently from the others (besner et al, 1997 and others), the presence of other people (huguet et al, 1999 and others), and suggestion (raz et al, 2002 and others). Differential effects of viewing positions on standard the end-letter position (as opposed to the ovp) would simply 3 butsee,forinstance,besner(2001), risko et .

Besner et al presented participants with color words in which only one letter was in a color that conflicted with the color of the word (eg, the word red with the e in blue) what happened to the stroop effect in this case. In the single-letter cued/colored condition, a target letter (any letter except the first or last letter of the word) was colored in one color and the remaining letters were all colored in another color from the response set. Journal of clinical and experimental neuropsychology this task involved presenting single letters or letter-cluster combinations simultaneously in the left and . The finding of a semantic effect triggered by the carrier word seems at odds with the data reported by besner and coworkers (besner and stolz, 1999a, b besner et al 1997) who showed that the stroop effect disappeared or diminished when only part (ie, a single letter) of a color word was colored the interpretation offered for those results . - the stroop effect is demonstrated by the reaction time to determine a color when the color is printed in a different color’s name participants respond slower or make more errors when the meaning of the word is incongruent with the color of the word.
Word is colored, stroop interference is reduced and in some circumstances even eliminated with rts longest in the incongruent-word condition.

Against this possibility are studies indicating that the stroop effect is attenuated or absent using a single letter format (besner et al, 1997, brown et al, 2002) functional imaging studies have also found that single letters do not reliably engage the fusiform visual word form area ( turkeltaub et al, 2008 ). In their experiments, besner et al (1997) nicely show a reduction and even a total elimination of the stroop effect when color was applied to a single letter instead of to all let-. For example, besner et al (1997) reported the elimination of the stroop effect, relative to a neutral baseline consisting of nonwords orthographically similar to color words (eg, ret) when a single letter was colored instead of the entire word.
