Objective: This study examined the differences in cerebral blood perfusion in concentration measures of 17 brain areas to low and high levels of self-reported anger in children. Method: Participants included 1,115 children, 71 % of which were males with a mean age of 11.91 (SD = 3.51). The data was derived from a de-identified database of children with a variety of psychiatric diagnoses given a baseline SPECT scan to measure rCBF and a second scan while completing the Connor's Continuous Performance Test. A variable of self-reported anger was created using 13 questions that targeted different areas of anger. Participant's parents rated each item subjectively on the high or low end and groups were created based on these ratings. Results: Independent samples T-tests were conducted between groups of high and low self-reported anger with concentration levels of rCBF in all 17 brain areas. With an alpha level of .01, statistically significant relationships were found between levels of self-reported anger with the right motor-sensory area (t(1074) = 2.858, p = .004), the left motor sensory area (t(1074) = 2.568, p = .01), and the right parietal lobe (t(1071) = 2.846, p = .005). Conclusion: Results show that children with higher levels of self-reported anger have higher rCBF in bilateral sensory motor regions and the right parietal lobe at concentration. Higher anger in children shows more activation in regions involved with sensory perception, positing that they are more sensitive to sensory input. Children with high anger more readily experience sensory input from the environment which may trigger angry and frustrated reactions. Extraneous sounds around a room may distract and anger these particular children in school and testing settings.
