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 …

The “Green Eating” Project: A Pilot Intervention to Promote Sustainable and Healthy Eating in College Students Kelleigh Eastman Sponsor: Geoffrey Greene, Nutrition and Dietetics A topic of interest that is growing in the general population is the idea of being sustainable, or “green”, and there is a rising awareness in sustainable practices involving food and the environment. Some of the “green” eating behaviors identified through my research included eating a plant-based (i.e. vegetarian or semi-vegetarian) diet, eating locally grown foods, eating organically grown foods, and eating foods that are labeled fair-trade. Frequently, these “green” eating behaviors are healthful eating behaviors …
Refeeding After Acute Food Restriction: Differential Reduction In Preference For Ethanol And Ethanol-Paired Flavors In Selectively Bred Rats., Clinton Chapman, Nancy Dess, Laura Cousins, Phuong Nguyen
Refeeding After Acute Food Restriction: Differential Reduction In Preference For Ethanol And Ethanol-Paired Flavors In Selectively Bred Rats., Clinton Chapman, Nancy Dess, Laura Cousins, Phuong Nguyen

Rats' voluntary ethanol intake varies with dispositional factors and energy status. The joint influences of these were of interest here. We previously reported that rats selectively bred for high voluntary saccharin intake (HiS) consume more ethanol and express more robust conditioning of preference for flavors paired with voluntarily consumed ethanol than do low-saccharin consuming counterparts (LoS). Three new experiments examined the effect of refeeding after an episode of food restriction on ethanol intake and on preference for ethanol-paired flavors in HiS and LoS rats. A 48-h episode of food restriction with wheel running reduced intake of and preference for 4% …
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
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 …
Free Will From The Neuroscience Point Of View, Armando F. Rocha, Fábio T. Rocha
Free Will From The Neuroscience Point Of View, Armando F. Rocha, Fábio T. Rocha
Armando F Rocha
There is still a controversy if human volitions and actions are governed by causal laws or obeys free will. Neurosciences start to study the neural correlates of free will by investigating how brains make decisions. Here, some of questions about free will are discussed from the neurosciences point of view taking into consideration a neuroeconomic model of decision making. This model is used here with the purpose of providing very formal definitions of key concepts raised in any free will discussion such as goals, necessity, motivation, etc., and to provide a formal background for discussing decision making. One of the …

The purpose of this investigation was to evaluate the effectiveness of a mental skills training (MST) program for male youth elite rugby athletes. Three focus groups were held with 21 under-16 male rugby athletes and four male coaches involved in the MST program to examine the quality of service delivery, athlete responses to the MST program, the mental qualities used by athletes, and its perceived influence on athlete performance. Following inductive-deductive content analysis, 40 subcategories and 16 categories emerged. Participants believed the MST program to be an interactive, well-planned program that increased athlete understanding of MST methods and awareness of …
News Of Corporate Failure: Evaluating The Relationship Between Individual Assessments And Market Investments, Ann Williams
News Of Corporate Failure: Evaluating The Relationship Between Individual Assessments And Market Investments, Ann Williams
Ann E Williams
Individuals’ comprehension of communication is shaped by the use of metaphor. This study illustrates how the use of metaphor in business and economic news coverage shapes individuals’ responsibility attributions in ways that can ultimately influence consumers’ investment decisions. In a randomized experimental design, participants were invited to read news articles that described the bankruptcy of a business. The treatment text narrated the bankruptcy using metaphor, while the control text narrated the same event without the use of metaphor. After exposure to the communication text narrated with metaphor, responsibility attributions and subsequent investment decisions were significantly altered. The findings suggest that …

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 …
