The revolutionary study by, Stroop (1935) used 5 different colors; purple, brown, green, blue, and red in a color-word naming task. Subjects had to say the color of the word while it was printed in different color ink. For example, the word “blue” would be written in the color red. They first did this using the colored words and then repeated the process with the words printed in black. They found that the colored word condition suggested a 2.3s longer reaction time than the black word condition. This is due to the inference of automatic word reading in the color word condition. Previous research also suggests that there can be interference with the use of the symbol of an arrow or the written words “right” and “left” in an experiment conducted by, Baldo, Shimamura, and Prinzmetal (1998). Their findings suggested that interference of an arrow or a printed direction was determined by the response modality; meaning either using a key press or responding vocally. They tested two conditions; 1) subjects would respond to a written direction manually and 2) where the subjects would respond to the direction of the arrow vocally. The data they collected pointed toward a larger interference when subjects were to respond to the written direction manually. There was a much less significant interference when subjects were to respond to the written direction vocally or when they were to respond to the arrow manually. Not only has irrelevant location been tested through a Stroop
