Two areas of the brain linked to action control<\/strong><\/p>\n The biopsychologists examined 264 women and men in an MRI scanner. They assessed the volume of individual brain regions and the functional connectivity between them. In addition, all participants completed a survey measuring their own ability to execute action control.<\/p>\n Individuals with poor action control had a larger amygdala. Moreover, the functional connection between the amygdala and the so-called dorsal anterior cingulate cortex (dorsal ACC) was less pronounced. “These two areas of the brain had already been linked with action control in former studies,” says Erhan Gen\u00e7.<\/p>\n Assessing and selecting actions<\/strong><\/p>\n The primary function of the amygdala is to assess different situations with regard to their respective outcomes and to warn us about potential negative consequences of particular actions. The dorsal ACC uses these information in order to select actions that are to be put into practice. Moreover, by suppressing competing actions and emotions, it ensures that the selected action can be successfully completed.<\/p>\n If the interplay between amygdala and dorsal ACC is impaired, action control can no longer be successfully executed, according to the theory put forward by the researchers. “Individuals with a higher amygdala volume may be more anxious about the negative consequences of an action — they tend to hesitate and put off things<\/strong>,” speculates Erhan Gen\u00e7. “Due to a low functional connection between amygdala and dorsal ACC, this effect may be augmented, as interfering negative emotions and alternative actions might not be sufficiently regulated.”<\/p>\n Learnable or not?<\/strong><\/p>\n Future studies will have to show if the degree of action control can be modified through specific training or brain stimulation. “Even though the differences regarding our ability to control our actions affect our private and professional success as well as our mental and physical health to a considerable degree, their neural foundations haven’t as yet been sufficiently studied,” says Caroline Schl\u00fcter, who addresses this issue in her PhD thesis.<\/p>\n<\/div>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the Ruhr-University Bochum press release: Researchers at Ruhr-Universit\u00e4t Bochum have analysed why certain people tend to put tasks off rather than tackling them directly.

Researchers at Ruhr-Universit\u00e4t Bochum have analysed why certain people tend to put tasks off rather than tackling them directly<\/strong>. Using magnetic resonance imaging (MRI), they identified two brain areas whose volume and functional connectivity are linked to an individual’s ability to control their actions<\/strong>. The research team headed by Caroline Schl\u00fcter, Dr. Marlies Pinnow, Professor Onur G\u00fcnt\u00fcrk\u00fcn, and Dr. Erhan Gen\u00e7 from the Department of Biopsychology published the results in the journal\u00a0Psychological Science<\/em>\u00a0on 17 August 2018.<\/p>\n
