Question

explain the stroop effect experiment how is it done.

Answer 1

According to the Stroop effect; word reading is a more automatic process than color naming among literate adults. Whereas color naming requires some attention capacity, word reading occurs quickly and effortlessly and requires no attention. Therefore individuals find it difficult to inhibit reading even in cases where they are instructed not to. This is done by asking the participants to read the names of a list of color words (e.g. blue, red, etc) under two conditions. In the first condition, they are asked to read words that are printed in black ink whereas in the other condition they are asked to read words which were printed in ink colors that did not match the color names. In the second experiment, the task is modified. This time, participants are asked to name colors instead of reading words. In one condition, participants name the color of square patches of color. In the other condition, they are given a list of words printed in incongruent colors (as in the first experiment) but are asked to name the color of the ink in which each word is printed. The difference in performance between the two conditions is striking: when asked to name the color of the square patches, participants have very little difficulty but when asked to name the color of the ink and ignore the word, their response time increases dramatically, as did the number of errors they make.
