Research by Dr. Abe et al. Reported on PsyPost

Research by Dr. Nobuhito Abe, et al. was reported on PsyPost (8/11/18), a psychology and neuroscience news website dedicated to reporting the latest research on human behavior, cognition, and society.



Dr. Abe was cited commenting on his research: “For many years, I have studied the neural basis of deception using a cognitive neuroscience approach.” “More recently, I’ve focused on the neural mechanisms of decision-making on how people behave honestly or dishonestly. It is well known that psychopathic individuals lie chronically, I was really excited to examine what brain mechanisms are associated with dishonest decision-making of psychopaths.” “The most important finding here is that higher psychopathy scores predicted decreased activity in the anterior cingulate cortex (ACC) during dishonest decision-making. And this ACC activity was a significant mediator of the relationship between psychopathic traits and reduced reaction time for dishonest behavior.”

This research paper entitled, “Reduced engagement of the anterior cingulate cortex in the dishonest decision-making of incarcerated psychopaths”, was published in “Social Cognitive & Affective neuroscience” in July, 2018.

『　Reduced engagement of the anterior cingulate cortex in the dishonest decision-making of incarcerated psychopaths　』

　A paper by Dr. Nobuhito Abe et al. was published in Oxford University Press’s Social Cognitive and Affective Neuroscience (online) on July 3rd, 2018.
Psychopathy is defined as a personality disorder characterized by anti-social behavior and a lack of empathy and remorse. People with psychopathy are believed to lie chronically, yet little is known about the neural substrates of dishonesty in psychopathy.
In this study, we used a mobile MRI scanner to conduct functional Magnetic Resonance Imaging (fMRI) study on incarcerated individuals in a North American correctional facility.
The results revealed that higher psychopathy scores predicted shorter reaction times for lying and decreased activity in the anterior cingulate cortex (ACC) during dishonest decision-making. These findings are the first in providing evidence suggesting that psychopathic individuals behave dishonestly with relatively low levels of response conflict.
