The Stroop Effect Explained

hello everyone maybe you've seen this before you're presented with a word like this and a state the color of the font if you haven't seen this before you should check out my other video how fast is your brain the Stroop test and have a goal with this task I'll put a link to the in the description anyway you're told to say the color of the font but first you pause for a moment as this is harder than you thought it would be and then eventually save the color that positive is called the super effect popularized by John Ridley Stroupe in 1935 essentially it's an interference in your mind between two conflicting pieces of information the word and the color of the words that causes the laughing cognition put another way it's a reason why it isn't hard to read this word or this word or identify this color but it's hard to take the color of this word okay that makes sense but why isn't it hard to read this word even though it's a different color I can easily read that it says purple well there are three leading theories on why this happens speed of processing Theory selective attention theory and the automatic word recognition hypothesis speed of processing theory suggests that it is easier for your brain to read words and to state the color of something such as a square similarly selective attention theory states that processing and naming colors require a lot more attention than reading words furthermore the automatic word recognition hypothesis suggests that people just read words automatically and it is a function that is impossible to turn off this obviously proves problematic when trying to identify the color of words and not the words themselves however reading that this word says purple is relatively easy okay clearly it is way easier to read words than to determine colors so much so that your brain automatically reads before even thinking about colors but how does this all come into play when doing the Stroop test so to visualize when you're told to state the color of this word your brain automatically reads the word first then your brain realizes that it needs to identify the color so it switches to that task it then proceeds the process the color which takes a lot of attention and then finally you successfully state the color hopefully this takes a while it has actually been shown in John Ridley Stroup's original research that people take 74% longer to state the Culliver words than the state the color of a generic square this is not surprising it's the process we just observed involved word recognition and task switching before mine could even begin to think about color processing through analyzing all this research one must wonder what the implications are for other situations like this in real life is our ability to switch tasks really that bad can our brain really be flown down that much when given conflicting formation at the same time it is definitely something to think about and has some serious video potential for the future thanks for watching and I'll see you next time you
