Lab 19: Psychological Model of the Stroop Task

• The Stroop task deals with colour words and the colour of the ink that they are printed in.
• If I present the word blue in blue ink to a subject and ask him to name the ink colour, he is fast and accurate.
• If on the other hand I present blue in red ink, he is slower and makes mistakes.

• Choose a language (C# is fine).
• Develop a simple model of the Stroop task (4 points). This doesn't need a gui, just reasonable output for an input (which can be read from the command line).
• You might want to look at the Stroop Wiki for more information and data points.
• Can you make the model account for statistical variance; a user doesn't always respond in the same time (3 points).
• Is this model a good cognitive model of the problem? (1 point)
• Could you describe (or even start to implement) a better model? (2 points)
