Why not try the experiment yourself? Brother Stroop's Enduring Effect. The experiment was carried out in an empty meeting room to provide an environment free from distractions with spares of all the materials. Equally significant, is the fact that the ISH has a very low population of high school students repeated measures experiment avoids this problem found in matched pairs and independent groups designs.
Furthermore, no participants were harmed, deceived or demeaned, physically nor psychologically and had the right to withdraw at any time. You may see your timings of you wish.
Eriksen Flanker Task. Null Hypothesis H0 : There will be no significant difference in mean time in seconds when naming shapes whether they are congruous or not; any difference that occurs is entirely due to chance or random variables not under control, and not due to the manipulation of the independent variable.
The table below Table 1 shows the mean, range and standard deviation results, in reference to measure of central tendency and dispersion.
The result was that interference occurred for naming the shape, much like the Stroop Effect. According to Hitatt and Newmanthis is a failure of response modulation that initiates the impulsivity identified in many psychopaths.
The first two tests were just for reference as a control but the last two showed the effect between the times of congruent and incongruent shape stimuli. Neutral List: Shapes in Word Form - 2. Participants fumbled through the list, finding it hard not to read the words instead of naming the colours.
However it is a rather inefficient testing method25and local control is completely neglected.
