Scientists have uncovered the foundations neyromolekulyarnye "illusion of superiority"

A group of Japanese and American researchers, following a large-scale interdisciplinary research aimed at studying the cognitive distortions, still known as the "illusion of superiority," revealed the neural and molecular mechanisms that are the basis of its formation, and the possibility of treatment of depressive realism. The information was published in the journal PNAS.

Human nature is characterized by highly controversial, as it is characterized, and optimism, and depression. One of the characteristics of our species, for example, is the ability to plan ahead and dream. But if the exercise of this power is not possible, the individual loses a sense of happiness and self-worth.

Some psychologists believe that all these aspects of human nature are closely related to concepts such as depressive realism and the illusion of superiority, the second can provide with a positive impact on the former. It was in depressive realism, according to experts, a person is able to more accurately perceive reality.

Under the illusion of superiority imply cognitive distortion, a condition in which a person is too overestimate their abilities and positive qualities: intelligence, cognitive abilities and underestimates the significance of deficiencies. Another cognitive impairment experts attribute bias illusion of control, optimism. Ultimately, however, the illusion of superiority is for most people a positive conviction, contributing to their mental health.

Without connecting sciences such as philosophy, psychology and neuroscience, a full understanding of the nature of human consciousness is impossible. Researchers at the National Institute of Radiological Research, Japan Agency for Science and Technology and the School of Medicine at Stanford University attempted to determine the origin of the illusion of superiority, but rather in the neural and molecular processes that cause this condition. Specialists in parallel led the study of the molecular and neural systems in the brain using positron emission tomography (PET) monitor the functioning of the brain at rest using functional magnetic resonance imaging (fMRI), as well as to determine the level of illusion of superiority with cognitive tasks.

A versatile approach has allowed scientists to discover a very interesting pattern. Level illusion of superiority, each individual is determined, as it turned out, the relationship between the work involved in learning and motivation of dopamine receptors and the functional relationship between the frontal cortex and striatum.

In addition, the research team analyzed the phenomenon of illusion of superiority, not only from the point of view of psychology and neuroscience, but also the philosophy and anthropology.

Thus, the researchers concluded that the illusion of superiority is the normal condition of man, and, as the results of analyzes, the brain is its support for neural and molecular level. Moreover, clinical depression, Parkinson’s disease affected by these subtle processes. However, new methods of treatment is still too early to say.

Lead author Makiko Yamada (Makiko Yamada) and his colleagues, according to Medical Xpress, hoping that in the future the results will help clarify the conditionality of the illusion of superiority from a biological point of view, as well as to identify potential methods of influence on the state of depressive realism.
