Impulsivity is one of the hallmarks of people with Attention Deficit Hyperactivity Disorder. This impulsivity is the result of the brain's decreased ability to inhibit. There is a lack of self-control even at the neurological level. Impulsivity is found in two areas. There is behavioral impulsivity, and there is cognitive impulsivity.

Behavioral impulsivity would involve actions, what one does. ADHD er's with behavioral impulsivity don't stop and think first before they act. No matter how many times you tell this kid, "stop and think first," the next time the situation comes up, he may well do the same impulsive thing again.

Kids with ADHD often aren't learning from their past mistakes. Their learning threshold is very high, and if you don't excite them, or motivate them enough to get them above that learning threshold, they don't learn, and they make the same the same mistake again and again.

ADHD er's with behavioral impulsivity act without thinking first, cut in line, can't wait their turn in line or in a game, blurt out answers in class, speak when they're supposed to be quiet, maybe show aggressive behaviors, are often a little too loud, and sometimes fights. They often have poor social skills, which of course is the death socially for teenagers with ADHD. They impulsively say the wrong thing at the wrong time. They can get one date, but they can't get the second date because they might impulsively blurt out something goofy, and then say, "Why did I say that?" Other teens are asking, "Who is this guy?" and often begin to avoid him.

Also, sometimes these kids fail to learn those subtle social cues that everybody else has learned, and so they're socially awkward and often don't know why.

Cognitive impulsivity is different. One with cognitive impulsivity is impulsive at the neurological level. This means that they guess a lot. In fact, guessing is their problem solving method of choice.

Cognitively impulsive ADHD kids will make a multiple number of guesses in a short period of time. On a matching task, or if you give them multiple choices orally, you'll see them guess for the right answer very quickly, "it's this one, no, its this one, no, wait, its this one," until finally you step in and, when he guesses right, you'll say, "That's it!"
