Experiment Author: Adapted from STEP (student submission to Research Methods class) and used with permission of Brian MacWhinney
Investigates whether seeing the name of an animal superimposed over a picture of an animal slows naming of the pictured animal.
In this adaptation of the Stroop Task, participants are shown a picture and name of an animal. The name of the animal is either congruent or incongruent with the picture of the animal. Participants vocalize the name of the animal in the picture and then press the spacebar. In the first block, the image and name are displayed simultaneously. In the second block the animal name is shown 200 milliseconds prior to the picture of the animal.
Respond by pressing the spacebar on the keyboard after vocalizing the name of the animal shown in the picture.
NOTE: To run the experiment, ensure that the graphic files are in the same folder as the .es/.es3 file.
