Atvainojos par kaviltāti, bet ceru, ka sapratīsies šos grafikus. Tātad pirmajā redzams dzeltens punktiņš, tā ir vieta, kurā tiek mērīta smadzeņu aktivitāte un tā atbild par vardarbības kontrolēšanu. Otrais zīmējums rāda, jo vairāk mēs skatāmies vardarbīgas programmas, jo vairāk samazinās mūsu apskatāmās zonas aktivitāte. Trešajā zīmējumā parāda, ja mēs skatāmies nevardarbīgas programmas, tad izmaiņas mūsu pētāmajā zonā netiek novērotas. Piedodiet nevelejos tulkot tadelj ka kadam intrese:
A secondary finding was that after repeated viewings of violence, an area of the brain associated with planning behaviors became more active. This lends further support to the idea that exposure to violence diminishes the brain’s ability to inhibit behavior-related processing. None of these changes in brain activity occurred when subjects watched non-violent but equally engaging movies depicting scenes of horror or physical activity. The yellow area shows the supplementary motor cortex, the part of the brain responsible for planning and imagining behaviors. The first graph illustrates that as the number of violent movies watched increased, the supplementary motor activity increased. The second graph shows that when subjects watched the non-violent control clips, there were no systematic changes in the activation of this area. “These changes in the brain’s behavioral control circuits were specific to the repeated exposure to the violent clips,” said Joy Hirsch, Ph.D., professor of Functional Neuroradiology, Psychology, and Neuroscience and Director of the Center for fMRI at CUMC, and the PLoS ONE paper’s senior author. “Even when the level of action in the control movies was comparable, we just did not observe the same changes in brain response that we did when the subjects viewed the violent clips.” “Depictions of violent acts have become very common in the popular media,” said Christopher Kelly, the first author on the paper and a current CUMC medical student. “Our findings demonstrate for the first time that watching media depictions of violence does influence processing in parts of the brain that control behaviors like aggression. This is an important finding, and further research should examine very closely how these changes affect real-life behavior.”
