A group version of the Stroop Color and Word Test

Summary: The uses of the Stroop Color and Word Test have been limited because of the lack of a standardized form, particularly one which could be used for both individual and group administrations as demanded by the requirements of a research project. The present version of the test counted the number of items completed by the subject in a 45-second time period. In the individual version the subject said the words out loud while in the group version he said the words to himself. Results indicated that the two versions were equivalent to each other as well as to forms requiring the subject to read a whole page of items. It was felt that a group form would greatly enhance the research capabilities of the Stroop Test.
