Brain Activity And Medical Diagnosis: An Eeg Study, Laila M. Ribas, Fábio T. Rocha, Neli R. Ortega, Armando F. Rocha, Eduardo Massad
Armando F Rocha
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 …
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 …
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 …
Development Of Response Evaluation And Decision (Red) And Antisocial Behavior In Childhood And Adolescence, Reid Griffith Fontaine, Chongming Yang, Kenneth A. Dodge, Gregory S. Pettit, John E. Bates
Development Of Response Evaluation And Decision (Red) And Antisocial Behavior In Childhood And Adolescence, Reid Griffith Fontaine, Chongming Yang, Kenneth A. Dodge, Gregory S. Pettit, John E. Bates
Reid G. Fontaine
Using longitudinal data on 585 youths (48% female; 17% African American, 2% other ethnic minority), the authors examined the development of social response evaluation and decision (RED) across childhood (Study 1; kindergarten through Grade 3) and adolescence (Study 2; Grades 8 and 11). Participants completed hypothetical-vignette-based RED assessments, and their antisocial behaviors were measured by multiple raters. Structural equation modeling and linear growth analyses indicated that children differentiate alternative responses by Grade 3, but these RED responses were not consistently related to antisocial behavior. Adolescent analyses provided support for a model of multiple evaluative domains of RED and showed strong …
On-Line Social Decision Making And Antisocial Behavior: Some Essential But Neglected Issues, Reid Griffith Fontaine
On-Line Social Decision Making And Antisocial Behavior: Some Essential But Neglected Issues, Reid Griffith Fontaine
Reid G. Fontaine
The last quarter century has witnessed considerable progress in the scientific study of social information processing (SIP) and aggressive behavior in children. SIP research has shown that social decision making in youth is particularly predictive of antisocial behavior, especially as children enter and progress through adolescence. In furtherance of this research, more sophisticated, elaborate models of on-line social decision making have been developed, by which various domains of evaluative judgment are hypothesized to account for both responsive decision making and behavior, as well as self-initiated, instrumental functioning. However, discussions of these models have neglected a number of key issues. In …
Toward A Conceptual Framework Of Instrumental Antisocial Decision-Making And Behavior In Youth, Reid G. Fontaine
Toward A Conceptual Framework Of Instrumental Antisocial Decision-Making And Behavior In Youth, Reid G. Fontaine
Reid G. Fontaine
This paper reviews and organizes relevant theory and research toward a conceptual framework of instrumental antisocial decision-making and behavior in youth. To date, social cognitive study of the development of youth antisocial functioning has largely focused on response patterns (e.g., cognitive responses to aversive cues). Though instrumental decision making is paid significant attention in research on adult criminality, there exists no framework by which youths' goal-driven behavioral decisions that are made in pursuit of antisocial motives and interests may be understood. This is a problem in that lessons from research on children and adolescents suggest that there are meaningful differences …
Real-Time Decision Making And Aggressive Behavior In Youth: A Heuristic Model Of Response Evaluation And Decision (Red), Reid Griffith Fontaine, Kenneth A. Dodge
Real-Time Decision Making And Aggressive Behavior In Youth: A Heuristic Model Of Response Evaluation And Decision (Red), Reid Griffith Fontaine, Kenneth A. Dodge
Reid G. Fontaine
Considerable scientific and intervention attention has been paid to judgment and decision-making systems associated with aggressive behavior in youth. However, most empirical studies have investigated social–cognitive correlates of stable child and adolescent aggressiveness, and less is known about real-time decision making to engage in aggressive behavior. A model of realtime decision making must incorporate both impulsive actions and rational thought. The present paper advances a process model (response evaluation and decision; RED) of real-time behavioral judgments and decision making in aggressive youths with mathematic representations that may be used to quantify response strength. These components are a heuristic to describe …
Evaluative Behavioral Judgments And Instrumental Antisocial Behaviors In Children And Adolescents, Reid G. Fontaine
Evaluative Behavioral Judgments And Instrumental Antisocial Behaviors In Children And Adolescents, Reid G. Fontaine
Reid G. Fontaine
There is a growing body of scientific research that has drawn a distinction between instrumental (or proactive) and reactive forms of aggressive behavior in children and adolescents. Whereas neurocognitive, psychophysiological, and other psychological factors have been shown to distinguish these aggressive subtypes, social cognitive research on alternative types of instrumental antisocial behavior (e.g., stealing, cheating, and illicit substance use) in youth is limited. Research on social information processing and aggression has shown that evaluative behavioral judgments may be of particular importance to understanding instrumental antisocial tendencies. Herein presented is a review of research on social cognition and discernible forms of …
Response Decision Processes And Externalizing Behavior Problems In Adolescents, Reid Griffith Fontaine, Virginia Salzer Burks, Kenneth A. Dodge
Response Decision Processes And Externalizing Behavior Problems In Adolescents, Reid Griffith Fontaine, Virginia Salzer Burks, Kenneth A. Dodge
Reid G. Fontaine
Externalizing behavior problems of 124 adolescents were assessed across Grades 7–11. In Grade 9, participants were also assessed across social-cognitive domains after imagining themselves as the object of provocations portrayed in six videotaped vignettes. Participants responded to vignette-based questions representing multiple processes of the response decision step of social information processing. Phase 1 of our investigation supported a two-factor model of the response evaluation process of response decision (response valuation and outcome expectancy). Phase 2 showed significant relations between the set of these response decision processes, as well as response selection, measured in Grade 9 and (a) externalizing behavior in …
