En teori siger at ADHD-personligheder lider af mangel på indre kemisk stimulation fra dopaminsystemet og derfor har brug for ekstra stærk ydre stimulation for at aktivere det system til at kompensere for underskudddet.
Jeg har tidligere været inde på to af psykologien anerkendte forskellige personlighedstyper: HSS´erne - High Sensation Seekers - og HSP´erne - Highly Sensitive Person.The low arousal theory is a psychological theory explaining that people with attention-deficit hyperactivity disorder (ADHD) seek self-stimulation or excessive activity in order to transcend their state of abnormally low arousal. The theory states that one with ADHD cannot self-moderate, and his or her attention can only be sustained by means of sustained external/environmental stimuli. This results in an inability to sustain attention on any task of waning stimulation or novelty, as well as explaining compulsivehyperactive behavior.Without enough stimulation coming from the environment, an ADHD patient will create it him or herself by walking around, fidgeting, talking, etc. This theory also explains why stimulant medications have high success rates and can induce a calming effect at therapeutic dosages among patients with ADHD. It establishes a strong link with scientific data that ADHD is connected to abnormalities with the neurochemical dopamine and a powerful link with low-stimulation PET scan results in ADHD subjects.
The ADHD brain may not be held back as much by constraints on thinking. In a study by Abraham et al. (2006), adolescents with ADHD, adolescents with conduct disorder, and a control group were each assessed with creativity measures. The ADHD group was found to have a higher rate of being able to overcome constraining examples ("thinking outside the box"), but had difficulty creating an invention from an imagery task.In a study by White and Shaw (2006), people with ADHD were found to score higher than those without ADHD in a measure of divergent thinking (ie. coming up with creative solutions to a problem). However, people with ADHD did not score as well as those without ADHD on a measure of convergent thinking (ie. giving the "correct" answer to a test question).A later study by White and Shaw (2011) found that people with ADHD scored higher in original creativity and creative achievement than those without ADHD. It was also found that people with ADHD preferred generating ideas, while those without ADHD preferred clarifying problems and developing ideas.
