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

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

Modeling Moral Dilemma Judgment, Armando F. Rocha, Fábio T. Rocha, Eduardo Massad
Armando F Rocha
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 …
The 2008 Crisis From The Neurofinance Perspective: Investor Humor And Market Sentiment, Armando F. Rocha
The 2008 Crisis From The Neurofinance Perspective: Investor Humor And Market Sentiment, Armando F. Rocha
Armando F Rocha
The world is still facing a financial crisis that started in mid 2007 and up to moment it is unsolved. Stock markets around the world reacted badly and the real time news has never played such an important role to investors as seen in previous crises. The impact of the media deepened the bear dynamics of markets around the world amplifying their volatility. Neurofinances is a new field of inquiring that has the purpose of studying decision making taking into consideration the role played by emotion. Here, we use these notions to develop a neurofinance modelling of the Brazilian stock …
Neurodynamics Of An Election, Armando F. Rocha, Fabio T. Rocha, Marcelo N. Burattini, Eduardo Massad
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) …
