- 2. A common activity of everyday life is identifying and understanding written words whether it is in books, billboards, signs, clothing, or even card games.In a Stroopexperiment, participants are asked to identify the color of a word.The words themselves are colors, e.g. red, purple, brown, and grey. However, the words are written in a different color, other than what the word itself says.The purpose is to study if there is a deviation between reaction times when the word and color match, a congruent condition, and when the word and color do not match, an incongruent condition.

- 3. HypothesesPrimaryThe backwards incongruent condition would be the slowest reaction time. SecondaryThe congruent condition would be the fastest reaction time.

- 11. DiscussionInternal Validity IssuesStimuli were not completely randomizedMore room for carryover effectThree participants participated in similar researchCorrelation to ResearchEffects of dyslexia on Stroop performancePhysiological inhibitors (parietal and frontal lobe lesions)
- 12. Physiological reasoningFrontal lobe and the parietal lobe lesions interfere with reaction times
- 13. Next StepsScreen for dyslexiaIs language a distracter?Is the Stroop effect still present with a single-letter incongruency

- #10: congruent and incongruent; congruent and backwards congruent; congruent and backwards incongruent; congruent and sideways incongruent; incongruent and backwards congruent; incongruent and backwards incongruent; backwards congruent and sideways congruent; backwards congruent and sideways incongruent; backwards incongruent and sideways congruent; sideways congruent and sideways incongruent.

- #13: The right medial frontal region (in red) involves planning, organizing, problem solving, selective attention, personality and a variety of "higher cognitive functions" including behavior and emotions. Selective attention includes overriding the automatic processing of reading.The left posterior parietal lobe (in green) includes the primary sensory cortex which controls sensation (touch, pressure). Damage to the left parietal lobe may disrupt a persons ability to understand spoken and/or written language.
