In the first experiment, he investigated the effects of verbal texts varying in their relationship to the colors. It consisted of six conditions in which each condition, the verbal text consisted of items typed in the colors red, green, yellow, and blue. The first condition had items that were nonsense syllables (hjh, evgjc, bhdr, gsxr); the second condition consisted of rare English words (sol, helot, eft, abjure); the third condition were common English words not closely associated with the color-names either in meaning or in response-class (put, heart, take, friend); the fourth condition were words that are not themselves color-names but connect the colors in their meaning (lemon, grass, fire, sky) and were presented in unrelated combinations with the colors; the fifth condition were different words of the same response-class (tan, purple, grey, black). The last condition was the 'standard ' condition: the words were the same as the color-names, but presented in different combinations of color and word. The participants were tested individually and first received two warm up tasks that they had to read aloud; one with the names of the colors red, blue, yellow, and green in black type and the other with asterisks printed in colored inks of red, blue, yellow, and green. The warm up tasks were then followed …show more content…
Each experimenter was given several answer sheets to record the incorrect responses, begin, end, total time, and total errors of each participant. The participants were given six stimulus sheets to read aloud from. Two were warm up tasks, which consisted of the colors red, green, blue, orange, purple written in black type and the other were asterisks printed in the color inks listed. The other four stimulus sheets were used as experiments to test for the Stroop effect. The first experiment sheet participants had to name the ink color going across which were the words (red, green, blue, orange and purple) written in incongruent ink colors. The second experiment sheet participants had to read the colors going across with the words (red, green, blue, orange and purple) written in incongruent ink colors. The third experiment sheet participants had to read the ink color going across for common words (put, take, friend, heart, boy) written in incongruent ink colors. The last experiment sheet participants had to read the word going across (put, take, friend, heart, boy) written in incongruent ink colors. Each stimulus sheet was constructed in random blocks containing 80 word units. The stimulus sheets were a partial replication of Klein’s first experiment in which we used most the same colors and common words but did not included nonsense syllables and rare English words and we did not use all the
