Moral thinking is related to the size of the gray matter in the brain

A study conducted jointly by the American University of Pennsylvania and the Shanghai University of China and the Berlin-based Friedrich-Ebert-Stiftung, Berlin, shows that individuals with a high level of moral thinking show increased activity in the reward center in the brain, While making decisions.

The findings, published in the August issue of Scientific Reports, may help researchers understand the differences in brain function among individuals in the various stages of ethical thinking, and why some individuals reach a high level of ethical thinking and are more likely to engage in some " Social behaviors, "such as performing community service or charity," based on more advanced principles and ethics. "

A number of previous medical research has indicated a correlation between high levels of ethical thinking and the size of gray matter in the brain. The present study sought to discover whether there is a link between moral thinking and brain functions.

In this study, researchers aimed to verify whether the development of ethics was linked to measurable aspects and brain functions. Therefore, they tried to test moral reasoning in a large sample of 700 MBA students, Brain reward and a subset of 64 students, whether they performed a task or not.

According to researcher Hengi Rao, an assistant professor of neuroscience knowledge, neuroscience and psychiatry at Shanghai University, the research team noted the large individual differences in levels of moral development in brain function.

The researchers stressed that it is completely established in the literature that the reward system in the brain involved in the rule of decision-making and social behavior, but it was not known in the past whether the function of the reward system in the brain affected by the stages of moral development or not.

This study is the first of its kind to demonstrate the effect of modulation on the level of ethical thinking on reward activity of the human brain. It also presents new insights on the possible neuropsychological basis and the psychotherapeutic mechanism underlying individual differences in moral development
