---- ---- Naming the font color of a printed word is an easier and quicker task if word meaning and font color are congruent. If two words are both printed in red, the average time to say "red" in response to the written word "green" is greater than the time to say "red" in response to the written word "mouse". In psychology, the<unk>  is the delay in reaction time between congruent and incongruent stimuli. The effect has been used to create a psychological test (the<unk>  test) that is widely used in clinical practice and investigation. A basic task that demonstrates this effect occurs when there is a mismatch between the name of a color (e.g., "blue", "green", or "red") and the color it is printed on (i.e., the word "red" printed in blue ink instead of red ink). When asked to name the color of the word it takes longer and is more prone to errors when the color of the ink does not match the name of the color. The effect is named after John Ridley<unk> , who first published the effect in English in 1935. The effect had previously been published in Germany in 1929 by other authors. The original paper by<unk>  has been one of the most cited papers in the history of experimental psychology, leading to more than 700<unk> -related articles in literature.
