It will be a modified experiment of the stroop effect experiment. The Stroop effect is an important base study to elaborate on more studies such as selective attention, speed processing theory and automatic processing. The research question is that is there interference to name the incongruent colour of the ink with a different colour word. This one-tail test is done so in repeated measures design with 20 participants through opportunity sample from a school. The researcher would ask the reader to read some experiments and time their time taken with a stopwatch to an accuracy of millisecond. The independent variables are congruent and incongruent colour of the words whereas dependent variable is the time taken to name the colour of the words. ...read more.

Middle

Ethical consideration should be given to everyone as the experiment may affect their psychological state or their everyday life. How the researcher treats the participants can be an ethical consideration to the experiment. After the experiment participants are not psychologically, physically, or emotionally hurt in any way possible. So this experiment can be considered ethical. Participants There will be 20 participants in total, 10 male and 10 female. They will be around 16-18 years old. The researcher's method of selection will be by opportunity sample. Opportunity sample is convenient and ethical. Materials Paper in coloured words (20 words: 10 congruent, 10 incongruent), (Refer to appendix iii) a quiet well lit room, stopwatch that measure up till millisecond, result table Procedure Firstly a hypothesis is formulated that the participants would take longer to name the colour ink than the words. They will be chosen at opportunity sample from a school. The experiment would then take placed in a quiet room. In addition, before they do the experiment they will listen to my standarised instruction and a consent letter will then need to be signed. During my standarised instruction I will aim to ease them to be comfortable and reassure them that the test would be anonymous as this could affect my experiment if the participants are tense. ...read more.

Conclusion

It is a surprise that the experiment with Stroop would be the same after replication but the replication is not greater in realibility, as the number of people and the depth does not go to his level of depth. Automatic processing may affect the naming of the words as human beings are used to or a nautral process to read the word of the colour rather than the colour of the word. This is because participants did not learn how to name the colour of the word in schools or when young or practice them so need a conscious effort to name the colour of the word. Selective attention may also affect the particpants as they might be distracted with other thoughts in their brain. Speed processing theory depends on individual so different people may vary in the speed of processing the information the participants read. In conclusion, there is interfernece in naming the incongruent colour of the ink with a different colour word. Conclusion The calculated vale is 4.626 and critical value is 1.729. So, calculated value is higher and we can say that the experimental hypothesis is accepted at a significance level p<0.05. Therefore, there is interference to name the incongruent and congruent, colour of the word and the colour of the ink. ...read more.
