What is the effect of conflicting information on reaction speed?

The Stroop Task studies how our brains deal with conflicting information by asking people to identify the color of words (e.g., the word "blue" written in red). It tests cognitive skills like attentional capacity and recruits frontal areas of the brain that are responsible for cognitive control (also known as executive function). Cognitive control may be harder under certain conditions (e.g., with lack of sleep) and for some people (e.g., children with Attention-Deficit / Hyperactivity Disorder, or ADHD). Some circumstances may also make the Stroop Task easier: for example if you are well-rested or if you are bilingual. The Flanker Task is another cognitive control task.

Parameters
The following features can be tweaked (default values in parentheses):

• Task instructions
• Number of main trials (96)
• Number of practice trials (8)
• Inter-trial interval (500 ms)
• Whether trial sequence should be randomized (yes)
  Note: practice and main trials are balanced across conditions (match/mismatch)

What data is collected? How is it scored?
The following variables are recorded:

• STROOP_reaction_time_match
• STROOP_reaction_time_mismatch
• STROOP_correct_response_proportion_match
• STROOP_correct_response_proportion_mismatch

The two central variables are reaction time and percentage of correct responses. These are further separated by condition (match, mismatch)
