Gun Control: What Goes On In Your Brain, Armando F. Rocha, Fabio T. Rocha, Eduardo Massad
Gun Control: What Goes On In Your Brain, Armando F. Rocha, Fabio T. Rocha, Eduardo Massad
Armando F Rocha
Arguments for and against gun control are polarized at two opposite ends of a broad spectrum: personal liberties and social benefits. Brazil has introduced a referendum regarding the prohibition of firearm commerce and propaganda arguments, similar to the present ongoing discussion in the U.S. It has invoked socially and personally driven issues in the promotion of voting in favor of and against firearm control, respectively. Here, we used electroencephalography (EEG) technology to study the brain activity associated with a voter’s perception one week prior to Election Day, of the truthfulness of these arguments and their influence on voting decisions. The …

Moral Dilemma Judgment: A Neuroeconomic Approach, Armando F. Rocha, Fábio T. Rocha, Eduardo Massad

Morals and ethics are important issues in human societies. Recently, the development of new techniques for studying the human brain has brought moral and ethical discussions to the realm of neuroscience investigations. Controversies still remain regarding the results of studies about morals and ethics and the understanding of the neurodynamics of dilemma judgment, which seems to depend on the nature of the studied dilemma (e.g., personal versus impersonal). Here, we proposed to understand the differences between personal and impersonal dilemmas in the context of losses modeled by neuroeconomic theory. The results show that the dilemma solution correlates nicely with the …

Moral dilemma judgment has been extensively studied by neurosciences and much is now known about the cerebral dynamics supporting this kind of reasoning. Neuroeconomics has provided some interesting hypothesis for modeling decision making. The present paper aims to test if dilemma judgment may be formalized by this kind of modeling. In addition, fMRI and electroencephalographic (EEG) studies have shown that dilemma judgment involves benefit and risk analysis supported by specific neural systems. Because of this, the EEG was recorded while volunteers were judging moral dilemma in order to provide additional information to test the proposed hypothesis. Present experimental and simulated …
