Question 3: The Stroop Effect [5 points] The Stroop Effect is a widely used paradigm in psychology research in order to understand how the brain processes information. In this task, people are asked to name the colour that a word is written is as quickly as possible For example, you would respond with 'blue for this word: BLUE and you would respond'red for this one: BLUE. When the colour of the word matches the word itself, this is called a congruent stimulus. When they do not match (like in the second word), it is an incongruent stimulus. People are generally slower at responding to incongruent words than they are to congruent words, because the tendency to read words interferes with naming the colour The file stroop_data.db contains data from a psychology experiment using the Stroop task (if you were in psych 1X03 in September 2017, you may have participated in this experiment). Each row in the database represents a single trial, or naming the colour of a single word. There is a column that represents accuracy as an integer, either 1. or 0.0. A trial with 1.0 is a correct trial, and 0. is an incorrect trial. The table was created using the following SQL command CREATE TABLE data (participant INTEGER, trial INTEGER, congruency TEXT, accuracy REAL, rt REAL); Here are the first few rows of the table participant trial congruency accuracy rt 1.0 409.99 1.0 368.86 1.0 601.52 1.0 393.04 1.0 672.82 Question 3: The Stroop Effect [5 points] The Stroop Effect is a widely used paradigm in psychology research in order to understand how the brain processes information.
