Moral Dilemma Judgment Revisited: A Loreta Analysis, Armando F. Rocha, Fábiot T. Rocha, Eduardo Massad
Moral Dilemma Judgment Revisited: A Loreta Analysis, Armando F. Rocha, Fábiot T. Rocha, Eduardo Massad
Armando F Rocha
Recent neuroscience investigations on moral judgment have provided useful information about how brain processes such complex decision making. All these studies so were fMRI investigations and therefore constrained by the poor resolution of this technique. Recent advances in electroencephalography (EEG) analysis provided by Low Resolution Tomogray (Loreta), Principal Component (PCA), Correlation and Regression Analysis improved EEG spatial resolution and make EEG a very useful technique in decision-making studies. Here, we reinvestigate previously fMRI study of personal (PD) and impersonal (ID) moral dilemma judgment, taking profit of these new EEG analysis improvements. Compared to the previous fMRI results, Loreta and PCA …

Despite new brain imaging techniques that have improved the study of the underlying processes of human decision-making, to the best of our knowledge, there have been very few studies that have attempted to investigate brain activity during medical diagnostic processing.The main purpose of this paper was to investigate brain electroencephalography (EEG) activity associated with diagnostic decision-making in the realm of veterinary medicine using X-rays as a fundamental auxiliary test. The principal component analysis revealed four patterns that accounted for 85% of the total variance in the EEG activity recorded while veterinary doctors read a clinical history, examined an X-ray image …
A Neuromarketing Study Of Consumer Satisfaction, Armando F. Rocha, Fábio T. Rocha, Lucia H. Arruda
A Neuromarketing Study Of Consumer Satisfaction, Armando F. Rocha, Fábio T. Rocha, Lucia H. Arruda
Armando F Rocha
The interest of marketing science in using neuroscience techniques to understand the consumer’s thought processes, dates back to the 1970s, when EEG data were recorded while subjects were watching TV commercials. Recently, fMRI was used to study the neural correlates of culturally based brands and neural predictors of purchases. These studies have discovered important properties of the neural circuits that are associated with consumer decision-making process and satisfaction. Here, EEG brain mapping was used to study the dynamics of the brain activity associated with these processes. The present study validated the EEG technology as an adequate neuromarketing tool and shows …
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 …
