This effect is called the stroop effect.

The Stroop experiment employs two basic processes of cognition; attention (“the concentration of mental effort on sensory or mental events”) and automaticity (“a cognitive process that does not require conscious though...

5. Now, perform the statistical test and report your results. What is your confidence level and your critical statistic value? Do you reject the null hypothesis or fail to reject it? Come to a conclusion in terms of the experiment task. Did the results match up with your expectations?

The aim of this experiment was to demonstrate how hard it is for a person’s attention to be divided in different tasks, by making the participants read a series of three stimuli which consisted of: 1) words of colors in black ink, 2) words of colors in their actual font color, and 3) color words with different ink, where the participant read the font instead of the word present....

Investigating the Stroop Effect :: Stroop Effect - …

Eye gaze is a window onto cognitive processing in tasks such as spatial memory, linguistic processing, and decision making. We present evidence that information derived from eye gaze can be used to change the course of individuals’ decisions, even when they are reasoning about high-level, moral issues. Previous studies have shown that when an experimenter actively controls what an individual sees the experimenter can affect simple decisions with alternatives of almost equal valence. Here we show that if an experimenter passively knows when individuals move their eyes the experimenter can change complex moral decisions. This causal effect is achieved by simply adjusting the timing of the decisions. We monitored participants’ eye movements during a two-alternative forced-choice task with moral questions. One option was randomly predetermined as a target. At the moment participants had fixated the target option for a set amount of time we terminated their deliberation and prompted them to choose between the two alternatives. Although participants were unaware of this gaze-contingent manipulation, their choices were systematically biased toward the target option. We conclude that even abstract moral cognition is partly constituted by interactions with the immediate environment and is likely supported by gaze-dependent decision processes. By tracking the interplay between individuals, their sensorimotor systems, and the environment, we can influence the outcome of a decision without directly manipulating the content of the information available to them.

(namely Stroop effect) for the most part

Choice blindness and preference change. We are interested in the effects receiving false feedback about one’s choices affects future preferences. We have shown that individuals’ will change their preference, in light of their beliefs about their past choices (). Ongoing projects in the lab are investigating these effects with more than one participant (dyads choosing together), as well as, the effects of choice blindness manipulations on individuals’ memories of their past preferences.

Experimenting with a variant of the stroop effect


The Stroop Effect is named after John Ridley Stroop, who published the effect in English in 1935 in an article entitled "Studies of interference in serial verbal reactions" that includes three different experiments.

Research has shown that people often exert control over their emotions. By modulating expressions, reappraising feelings, and redirecting attention, they can regulate their emotional experience. These findings have contributed to a blurring of the traditional boundaries between cognitive and emotional processes, and it has been suggested that emotional signals are produced in a goal-directed way and monitored for errors like other intentional actions. However, this interesting possibility has never been experimentally tested. To this end, we created a digital audio platform to covertly modify the emotional tone of participants’ voices while they talked in the direction of happiness, sadness, or fear. The result showed that the audio transformations were being perceived as natural examples of the intended emotions, but the great majority of the participants, nevertheless, remained unaware that their own voices were being manipulated. This finding indicates that people are not continuously monitoring their own voice to make sure that it meets a predetermined emotional target. Instead, as a consequence of listening to their altered voices, the emotional state of the participants changed in congruence with the emotion portrayed, which was measured by both self-report and skin conductance level. This change is the first evidence, to our knowledge, of peripheral feedback effects on emotional experience in the auditory domain. As such, our result reinforces the wider framework of self-perception theory: that we often use the same inferential strategies to understand ourselves as those that we use to understand others.
