Stroop effect lab report

Journal Jensen, A. For this task the stimulus card outlined in coloured text each of the four colours previously prescribed in the preceding tasks.

Stroop test results meaning

Color association values and response interference on variants of the Stroop test. Procedure As participants entered the class room, they were instructed to separate into groups of three. Cattell described this in the case of words and letters, that the cognitive association between the word and the idea of the word has been already taken place and become automatic due to common use of the word as described by MacLeod , p. What is the Stroop Effect? Acta Psychologica, [online] 25, pp. It was shown that naming speed was slowed when the words were conflicting colour names. The final activity was the Stoop task where interference was introduced. The hypotheses that are being studied are whether participants will complete the word task significantly faster than the coloured blocks task speed of processing or whether participants will complete the coloured blocks task significantly faster than the Stroop task where interference is introduced and if there is a higher margin for error between the Stroop task and the other tasks. Psychonomic Science, [online] 9 8 , pp. Instructions appeared on the screen describing to the participants what was going to happen next. There have been numerous studies undertaken to demonstrate the Stroop effect and interference including for example the picture-word interference task e. Participants varied in age M The stress of Stroop performance: physiological and emotional responses to color—word interference, task pacing, and pacing speed. The colour of the text did not correspond with the colour worded; green coloured text was used for the words red, blue or yellow; red coloured text was used for the words green, blue or yellow; blue coloured text was used for the words red, green or yellow and finally yellow coloured text for the words blue, red or green.

The effects of stress on Stroop color-word performance. The second activity was the coloured block task where the stimulus card outlined the colours red, green, blue and yellow as blocks of colour rather than text as in the previous task.

In the experiment participants had to name the colours in which the words were printed as rapidly as possible.

Color association values and response interference on variants of the Stroop test. Journal Scheibe, K. The colour of the text did not correspond with the colour worded; green coloured text was used for the words red, blue or yellow; red coloured text was used for the words green, blue or yellow; blue coloured text was used for the words red, green or yellow and finally yellow coloured text for the words blue, red or green. Method: The experimenter first of all instructed the participants to turn on the computer. The aim of this lab report is to demonstrate the Stroop effect Stroop, Acta Psychologica, [online] 25, pp. New York: H. Responders were instructed to read the text from right to left as quickly as possible whilst being timed by the timekeeper.

Page 1 of 7 Abstract The aim of this lab report is to explore the Stroop effect Stroop, by comparing the performance, speed and accuracy of participants in an experiment where interference hinders their responses.

Flowers et al. Each experiment introduced interference in the form of conflicting colours in relation to the word and measured the speed in which responses were provided. Psychonomic Science, [online] 23 2pp.

Method: The experimenter first of all instructed the participants to turn on the computer. The three tasks within this experiment are the word task, the coloured block task and the Stroop task. There are three tasks set out on the stimulus card and the response sheet which identified the correct answers to the corresponding tasks.
