Question

Background: 100 ms after the participant makes an er investigate whether the ERN is affected The Error-Related Negativity (ERN) is a negative ERP component a negative ERP component that peaks around 80- me participant makes an error Chan Davies & Gavin (2009) Wanted (ADHD). They compared a group of college students who had mer the ERN is affected by Attention Deficit Hyperactivity Disorder of college students who had ADHD to a control group Eroup, the dashed line represents the control aroun. The vertical line show V ADHD. Here is part of their results The solid line represents the one control group. The vertical line shows the time when for (pressed the wrong button). Positive is upward. cir results. 1. vertical line is upware who did not have ADHD. Here is part of the the participants made the error (pressed the wrong button). -500 400 time (milliseconds) Questions: 1. Circle the approximate location of the ERN above. 2. Is the ERN amplitude larger, smaller or about the same in the ADHD group compared to the control? Circle one: Larger Smaller The same 3. Draw on the graph below how you can tell whether the amplitude is larger, smaller or the same. FCzy -600 400 200 0 200 400 600 800 time (milliseconds)

Answer 1

ANS:-

ne ERN & The ERN i Located in the area of the diagoram within the pink box drawn in figure. & ERN amplitude is smaller in ADHD goroup compared to contool. 3 please refer to the first figure in which red line indicated the amplitude of ADHO at ię smalled when compared to control. Group peak 4, ERN Latency is shooiten, in ADHD 1 group than in control 5 ERN Latency is smallen shown by - blue line of dot when compared to contorol dotted Line. * Please "Rate" if it's Helpful, thank you *
