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 …

Brain Activity Of Normal And Low Iq Children: The Neural Efficiency Hypothesi, Fabio T. Rocha, Armando F. Rocha, Sueli Angeloti

The neural efficiency hypothesis (NEH) of intelligence claims that subjects performing a complex task may well use a limited number of brain circuits and/or fewer neurons while poor performers use more circuits and/or neurons, some of which are inessential or detrimental to task performance. The present paper studies the EEG activity associated with reading and arithmetic calculation by normal and mental retarded children. Correlation analysis of the electrical activity recorded by 10/20 electrode system was used to calculate the amount of information allocated by individuals to solve these tasks. Multiple regression analyses showed that IQ linearly correlates with the amount …

Neurodynamics Of An Election, Armando F. Rocha, Fabio T. Rocha, Marcelo N. Burattini, Eduardo Massad

Variables influencing decision-making in real settings, as in the case of voting decisions, are uncontrollable and in many times even unknown to the experimenter. In this case, the experimenter has to study the intention to decide (vote) as close as possible in time to the moment of the real decision (election day). Here, we investigated the brain activity associated with the voting intention declared 1 week before the election day of the Brazilian Firearms Control Referendum about prohibiting the commerce of firearms. Two alliances arose in the Congress to run the campaigns for YES (for the prohibition of firearm commerce) …
