The Stroop Word Color Test Essay

1019 words - 4 pages

Introduction:
In this Stroop experiment we attempt to investigate the inference in perception by showing 20 participants a Stroop color model and a controlled black and white model and compare the reaction times of the two.
Stroop investigated in interference in perception demonstrating perception is a dynamic process open to influence. The Stroop word-color test can be modified into other languages other than English, thereby demonstrating how the Stroop Effect "works" across a range of languages, i.e. it is cross-cultural.
In the traditional Stroop effect, naming the print color of a word is delayed if the word itself is a color word which names a different color (e.g., responding "red" to the word "blue" displayed in red letters is slower than responding "red" to a red patch of color).
Stroop interference is where "words are processed faster than are colors." It is true that reading words is faster than naming colors, but this seems to be a matter of response compatibility, rather than perceptual speed.
Color words interfere with color naming because they are automatically processed.

Aim:
The aim of this study is to investigate the inference in perception of a Stroop color model compared to a simple black and white variation of the Stroop color model.

Experimental Hypothesis:
I predict that the results will show that the model with the words simply in black will show faster times because there is no interference with what the participants are reading, they are simply reading normal black and white text as seen in any book or paper etc. Word colour incongruence will slow word recognition.

Null Hypothesis:
I predict that the results will show that the model with the color words will show faster reaction times because like with perceptual set, humans can choose to ignore certain aspects of sensory objects and they know what they have to ignore so they are prepared to interpret the model in a certain way. Word colour incongruence will not slow word recognition.

Method:
Design:
The variables we are presented with in this experiment are a dependent variable, and independent variable, and a controlled variable. The independent variable is the interference in perception put to use by changing the color of the words. The dependent variable is the processing and this is put to use by the time taken to read the words.
There are no ethical considerations in this experiment because all participants were debriefed and signed a consent form, and no psychological or physical harm was done.

Participants:
The target population was 11th graders and teachers from UNIS (The United Nations International School in Hanoi). The participants come from all different parts of the world to ensure diversity and eliminate any cultural bias or concerns. The participants were both male and female and their ages ranged from 16 to 45. This sample was an opportunity sample because it was the most convenient and hassle free method of...

The overall nature of the study however has been repeated with different control conditions and the results yield the same idea: it takes longer to say the color of the word due to interference. There are a variety of factors that can affect performance on a Stroop test, such as what words are used. Williams, Mathews, and MacLeod

The experiment consisted of 7 color naming lists; it started with a

(MacLeod, 1991) Many believe Stroop’s study was a landmark, or as MacLeod (1992) calls it, “The Gold Standard” for attentional research. In his original study, Stroop found that naming the color ink of a word was interfered by automatic reading of the word. For example, printed in yellow ink, was the word green. When instructed to say the color of

In this experiment, the color of the print was the dependent variable. This meant that the students were supposed to identify with the color of the print, but not on the name that was read out (Stroop, 1935). The experiment had 100 students taking part, 88 of them being undergraduate students and 12 being graduates

We believe that it was due to having bias in the experiment such as American Sign Language translation, color blind, misunderstanding the meaning of anxiety, and reading level within the deaf participants. Conclusion Due to the result of the experiment, it doesn’t seem to fit to the theory from previous studies

Incongruent ink color and color name caused a longer response time in comparison to congruent and color only conditions; it also had more trial errors. Like the Stroop (1935) research, our research focused on the interference of word stimuli on naming colors. Instead of using vocal modality our research however, used

In the Stroop color test, participants are instructed to

Lab Report: The Stroop Effect

741 words - 3 pages Introduction.The 'Stroop Effect' was first introduced in 1935. It originated from the theory of automatic processes. It is clear that some processing activities become automatic as a result of prolonged practice eg. Typing, driving, etc. Automatic processes therefore are fast, require no attention and are unavoidable. Stroop believed that there was some evidence that word identification may be a form of an automatic process. In the experiment
