Take the following into account when designing the Stroop task for the MRI protocol:. Split the Stroop task into at least two separate runs to avoid fatigue-related performance decline. It is recommended to use the same number of total trials in both the MRI and behavioral sessions. Ensure that each run has an equal number of congruent and incongruent stimuli e. Ensure that the colored letters remain on screen for the same amount of time during each trial e. Ensure that the letters are not removed from the screen upon the event of a button-press.

Instruct participants that this is the case. Inform them that they should not expect the letters to immediately disappear upon a response as they do in the behavioral lab and that they may assume that their responses are recorded so long as they push the buttons. Make sure to independently verify that the responses are being logged properly. Measure the participants' reaction time and accuracy on each trial while acquiring functional MRI images. In addition to functional imaging, structural images may also be acquired before and after reading during the scan sessions.

For example, T1-weighted images that can be used in voxel-based morphometry 38 and cortical-surface area analyses 39 , and diffusion-weighted images that can be used in fractional anisotropy 40 or tractography analyses We recommend acquiring two T1-weighted volumes and four diffusion-weighted runs per testing session. Evaluate the participants' experiences of reading in color. An example questionnaire is given in Appendix B. After both testing sessions are completed, begin the data analysis to test for learned associations between letters and colors from reading in color.

Only correct trials should be included in the reaction time analysis. A learned association is measured here by the size of the Stroop effect: the difference between incongruent and congruent stimuli in reaction times and accuracy. The Stroop effect is measured before and after reading. A significant interaction between testing session and congruency means that the Stroop effect is significantly different after reading compared to before reading, implying that the letter-color association has changed due to reading in color.

The effect should be in the expected direction, namely that the Stroop effect is significantly larger after reading compared to before reading. An example of a significant interaction is illustrated in Figure 3. The Stroop effect in accuracy may be significantly different after reading compared to before reading. Since accuracy tends to be very high on this task, it is not always the case that a significant interaction between testing session and congruency is found for accuracy.

Keep in mind that there are large individual differences in the learning effect and that these statistics are representative at the group level. It is possible that there is an interaction between letter frequency and pre-existing letter-color pair preferences in the sample. In other words, assigning participants their preferred colors to the high-frequency letters and nonpreferred colors to the low-frequency letters preference group 1 had an impact on the resulting change in the size of the Stroop effect compared to when participants are assigned their nonpreferred colors to the high-frequency letters and preferred colors to the low-frequency letters preference group 2.

For example, the change in the Stroop effect after reading may be significantly bigger in preference group 2 compared to preference group 1, indicating that pre-existing letter-color preferences interacted with the frequency of letter presentation. To test for this effect, first ensure that there are no unwanted significant differences between the mean i. Furthermore, check whether both preference groups have read the same amount of words or characters.

In order to test an interaction between letter frequency and letter-color preference, 'preference group' can be included as a between-subjects factor in the analysis of factors: testing session and congruency. If a significant interaction effect with preference group is found, it can indicate that pre-existing associations between letters and colors are dependent on the frequency of letter presentation.

An example of such an interaction is illustrated in Figure 4. It is also good to check whether the interaction between testing session and congruency is significant in both preference groups separately. If it were significant in one group, this would indicate that this preference group is driving the combined results of both groups most likely preference group 2. The interaction between letter-color pair preference and relative letter frequency is an interesting path for future research. In order to probe for individual differences in learning the letter-color associations, several correlation analyses can be carried out and should be corrected for multiple comparisons.

For example, word count or character count the number of words or characters each participant read in color between testing sessions can be correlated with the Stroop effect found after reading. Typically, we do not find a significant correlation between either word or character count and the Stroop effect when the sample size has been between participants, indicating that some participants who read more than others did not necessarily develop a larger Stroop effect compared to others who read less and were inherently more sensitive to developing these associations.

For the brain imaging analysis, the interaction between testing session and congruency should be significant in order to verify that training letter-color associations by reading in color had a significant effect on brain activation.

We suggest using a standard analysis pipeline for preprocessing functional MRI data 42 , including motion correction, and the general linear model GLM for the statistical analysis If reading in color affects brain function in certain areas, then brain activation within these contrasts should be significantly different after reading compared to before reading. We are able to provide an example of brain activation from the post-reading session related to these contrasts at the single-subject level is illustrated in Figure 5 i. In order to test for differences in brain structure, we refer researchers to follow standard protocols We have yet to determine if reading in color may affect grey or white matter structures in the brain.

The degree to which an individual reports internalizing the color experience may positively correlate with the size of the post-reading Stroop effect. Significant results should be corrected for multiple comparisons. Possible correction methods include Bonferroni correction 44 , or alternatively, the false discovery rate 45 FDR.

In this example, the red stimuli are congruent, and the green stimuli are incongruent. Figure 3: An example of a significant interaction between testing session and letter-color congruency. Error bars represent the standard error of the mean. A The difference in reaction times between incongruent and congruent stimuli before and after reading. Participants will be slower in reacting to incongruently colored letters compared to congruently colored letters.

B The difference in accuracy between congruent and incongruent stimuli before and after reading. Participants will often be more accurate on congruent trials compared to incongruent trials after reading. Figure 4: An example of a possible interaction between preference group, testing session and congruency.

In this example data, preference group 1 has a pre-existing Stroop effect, while preference group 2 does not. Preference group 1 has been assigned their preferences to the high-frequency letters e and n and their nonpreferences to the low-frequency letters a and r , while preference group 2 has been assigned their nonpreferences to the high-frequency letters e and n and their preferences to the low-frequency letters a and r. This graph illustrates that pre-existing preferences for letter-color pairs may possibly have an effect on subsequent results Click here to view larger image.

Coordinates are in MNI space. We have described a basic method for training and testing letter-color associations through reading in color. An important aspect for this method to work properly is that the individual participants are each motivated to read the colored books, have done so, and reported the duration and amount of reading honestly, since they cannot be directly observed in the lab.

In case the expected results are not obtained, it is important to rule out that a null effect or lack of a Stroop effect is simply due to the fact that the participants did not actually read the colored text. One way to ensure that participants have done the reading is for the experimenter s to read the books in order to converse with the participants about their contents. In terms of data analyses, decide before beginning the experiment whether outliers will be removed from the reaction time data. Our standard is that response times less than msec and greater than 2.

Color And Conversions

Before testing begins, it is good practice to determine a minimum criterion for the amount of reading necessary we suggest around 40, words as a guideline and to exclude participants who have not read at least this amount. Also, consider excluding participants who have stopped reading a certain number of days before the testing session.

After the data has been collected, make sure that only correct trials are included in the reaction time analysis and check for speed-accuracy tradeoffs. Also, check the accuracy on the color-key response training to make sure that participants learned which key goes with which color. Watching the participants when doing the color-key training to make sure that they are able to do the task without looking at their fingers ensures the quality of the data to be collected.

Consider checking whether the Stroop effect is present in most or all of the participants or whether only a few participants with very strong effects seem to be driving the group-level effects. Similarly, check whether one of the preference groups is driving the effects in our experience, preference group 2 typically showed a larger change in the Stroop effect due to reading. In the brain imaging functional data, ensure that the quality of the data is good enough by testing for significant de activation for all stimuli regardless of congruency.

Furthermore, consider adding respiration and heart rate as confound regressors in your GLM analysis. Another control measure during scanning is the use of an eye-tracker to ensure that the participants are indeed watching the screen, doing the task properly and not asleep. Short runs less than 10 min help to avoid concentration and fatigue issues.

The interpretation of brain activation related to trained letter-color associations in the Stroop task remains an interesting line for future research. The synesthetic version of the Stroop task has not been employed in many fMRI studies on grapheme-color synesthesia Two studies have tested synesthetes using a comparable synesthetic Stroop task in an fMRI paradigm, but they did not report comparable contrasts 48, Concerning the brain imaging structural data, consider using the significant clusters of activation found during the Stroop task as masks for regions of interests in the statistical analyses of the structural images.

In addition, consider correlating white and grey matter properties with behavior on the Stroop task in order to test whether macroscopic brain structures predict inter-individual differences in performance and learning. There are many aspects of the current protocol that can be changed based on the research goal of the experiment at hand. In the Stroop task, for example, the number of letters and colors trained can vary. It should be noted that increasing the number of colors tested would increase the necessary number of response options during the Stroop task affecting the experimental paradigm.

The Psychology Of Color

Some researchers use a microphone to record vocal responses in the computer lab, although this is not as practical in the MRI scanner. A baseline condition can be added to the Stroop task in addition to the congruent and incongruent conditions , in which letters that have not been colored in the books are presented in the same colors used for the congruent and incongruent conditions. Using a baseline condition can allow better inference as to how the congruent and incongruent conditions change over time in comparison to any change in the baseline condition.

The duration and amount of reading may vary and may also be a variable of interest decided upon by the researchers, as well as the time in between reading the last colored book and the last testing session. Many other cognitive and perceptual tasks and questionnaires can be added to the protocol. Lastly, the protocol may be easily combined with other neuroimaging techniques. The presence of a synesthetic Stroop effect in trainee data mimics the behavior on the same task found in grapheme-color synesthetes 18,27, We would like to stress the fact that the presence of a Stroop effect is not enough to claim that trainees have genuine synesthesia.

Developmental synesthesia is defined by more than just a synesthetic Stroop effect or perceptual color experiences, such as consistency of the letter-color associations over time with an onset in early childhood 51 , differences in the function and structure of the brain 12 , and a possible genetic predisposition 13,14 for a discussion about defining synesthesia, see references Therefore, we prefer the term 'pseudo-synesthesia', in order to differentiate trainees even if they would report color experiences from grapheme-color synesthetes, who report the experience of synesthetic associations for as long as they can remember.

Individual differences in the learning effect i. Such a correlation does not provide definitive proof that color experiences related to the trained letters are perceptual in nature and not solely semantic propositional associations. It remains to be seen whether trained letter-color associations go beyond semantic associations by having similar qualities as visual mental images or veridical perception. Reading in color is a method for training letter-color associations. This method can be used to examine the extent to which cognitive advantages seen in synesthesia, such as better memory for certain stimuli categories may be trained in nonsynesthetes and whether this training may induce changes in the brains of the trainees.

It is promising in the sense that there is still much to learn concerning the effects of both short-term and long-term 'reading in color' training methods. We hope that by providing the basic protocol that we have developed, others will use it to progress not just the field of training synesthesia research, but the cognitive neuroscience of learning and memory as well.

The following shade of green, however, is not very feminine: So the shade would need to be a little light If you also want to convey a bit of tranquility, you would add a bit of blue. Studies suggest that people make a subconscious judgment about a product within 90 seconds of initial viewing.

Brand recognition is directly tied to consumer confidence. Colors are not universal in nature. Colors that entice in North America are different from those that entice in India. See the infographic below to see how different colors affect online consumers in North America. Color is not the only element that influences consumer behavior.

For online shoppers, design, buzzwords and convenience also affect the need to shop. In general, research says that gender associations with color are ambiguous.

An even earlier study by Jastrow found men preferred blue to red and women red to blue. This finding was reinforced later by Birren who found men preferred orange to yellow; while women placed orange at the bottom of the list. Guilford and Smith found men were generally more tolerant toward achromatic colors than women. Thus, Guilford and Smith proposed that women might be more color-conscious and their color tastes more flexible and diverse.

Likewise, McInnis and Shearer found that blue green was more favored among women than men, and women preferred tints more than shades. In a similar study, Plater found men had a tendency to prefer stronger chromas than women. Brightness rightness, for the purpose of this discussion, is defined as the intensity of light illuminating an object.
