Abstract:
This experiment is to investigate the effect of color interference in speed estimates of the Stroop task which was first researched by John Ridley Stroop in 1935. This can be investigated by seeing the time difference between the task of identifying colors when color words are printed in the same color as their semantic meaning (test #1) and when they are printed in different colors as their semantic meaning (test #2). The research hypothesis is that the average time will be higher in test #2 because of the interference in the color detection task. The experiment uses independent measures and opportunity sampling of bilingual students aged from 16 to 18 years old. The results supported the hypothesis since the participants who did test #2 took 8.8 seconds in average longer than participants who did test #1.
Introduction
The aim of this study is to investigate the effect of interference on speed estimates during the Stroop task. The Stroop task was first experimented by John Ridley Stroop in 1935. The Stroop Effect involving the Stroop task refers to a phenomenon in which it is easier to say the color of a word if it matches the semantic meaning of the word.
Stroop (1935) began investigating the phenomenon of interference by using a color-naming task. The experiment was called ““The Effect of Interfering Color Stimuli Upon Reading Names of Colors Serially” in which he conducted on seventy college undergraduates (14 males and 56 females). In the experiment, the participants were to do two tests, one test is with a list of words printed in black and another test is with a list of words printed in colors (red, blue, green, brown and purple) different from its name (e.g. blue printed in red). The colored words were arranged so that each color would appear twice in each column and row and no
