By Sunidhi Ramesh Racial and ethnic discrimination have taken various forms in the United States since its formation as a nation. The sign in the image reads: "Deport all Iranians. Get the hell out of my country." Image courtesy of Wikipedia . From 245 years of slavery to indirect racism in police sanctioning and force, minority belittlement has remained rampant in American society (1). There is no doubt that this history has left minorities in the United States with a differential understanding of what it means to be American and, more importantly, what it means to be an individual in a larger humankind. Generally, our day-to-day experiences shape the values, beliefs, and attitudes that allow us to navigate the real world (2). And so, with regards to minorities, consistent exposure to these subjective experiences (of belittlement and discrimination, for example) can begin to shape subjective perceptions that, in turn, can mold larger perspectives and viewpoints. Last spring,...

by Lindsey Grubbs Early in April, Emory University hosted the third iteration of Critical Juncture . This annual(ish) graduate-student-led conference focuses on intersectionality , examining interconnecting dynamics of systems of oppression including racism, sexism, ableism, and classism. This year’s conference, while maintaining a broader focus on the complexities of identity and oppression, took as its theme “representations of the body”: which bodies are, and perhaps more importantly which are not, represented in science, politics, the arts, and the academy, and what forms do these representations take? From its beginning, the conference has links to neuroethics at Emory. One of the co-founders of the conference, Jennifer Sarrett , was a past Neuroethics Scholars Program Fellow. This year, I—one-time managing editor of this blog and current intrepid neuroethics blogger—served as one of the co-organizers. The focus at this year’s conference was on increasing opportunities for in...

by Arthur T. Ryan, M.A. and Elaine F. Walker, Ph.D. Arthur Ryan is a graduate student in clinical psychology at Emory University. His research focuses on understanding the etiology and neuropathology underlying severe mental illness. Elaine Walker is a Professor of Psychology and Neuroscience in the Department of Psychology at Emory University and is the Director of the Development and Mental Health Research Program, which is supported by the National Institute of Mental Health. Her research is focused on child and adolescent development and the brain changes that are associated with adolescence. She is also a member of the AJOB Neuroscience editorial board. Arthur Ryan, M.A. Over the past several decades, there has been a significant effort to minimize bias against individuals based on ethnicity and other demographic factors through the creation of seemingly impartial and objective criteria across a host of domains. For example, when the United States Federal Sentencing Guidelines wer...

Mallory Bowers is a 5th year Neuroscience doctoral candidate working with Dr. Kerry Ressler at Emory University. Prior to graduate school, Mallory received her Bachelor of Arts from the University of Pennsylvania. Mallory is interested in behavioral neuroscience, with a particular focus on how neural plasticity contributes to learning. With Dr. Ressler, Mallory is using a mouse model of exposure-based psychotherapy to better understand the neurobiology of learned fear. Specifically, her research focuses on a potential interaction between the cholecystokinin and endogenous cannabinoid systems that may underlie extinction of cued fear. Mallory was on the organizing committee for the 2013 “Bias in the Academy” Conference and is President of Emory Women in Neuroscience (E-WIN). As I’ve become more entrenched in the PTSD field, I’ve been struck by the prominent sex/gender difference in the prevalence of PTSD (among many other psychiatric disorders) and the categorical use of male animal m...

Our everyday perceptions of others can potentially be biased by cultural stereotypes. However, research has suggested that an initial, and often negative, stereotype can be downregulated via a highly connected neural network. While this regulatory process has been studied under neutral conditions, for the third journal club of the semester Neuroscience graduate student Kim Lang led a discussion about regulation of this neural network when White individuals are not under neutral conditions, but actually primed for negative African American stereotyping. A recent paper published by Forbes et al. used functional magnetic resonance imaging (fMRI) to study the amygdala, the prefrontal cortex (PFC), and the orbitofrontal cortex (OFC), three highly interconnected brain regions important for stereotyping and bias. Studies have shown that the amygdala, involved in arousal, is activated immediately when encountering a so-called out-group member. This first response can be downregulated though if...

By Emily Young In the early 1900s, psychologist Charles Spearman noticed that children who did well in one subject in school were likely to do well in other subjects as well, and those who did poorly in one subject were likely to do poorly across all subjects. He concluded that there is a factor, g, which correlates with testing performance (Spearman 1904). The g factor is defined as the measure of the variance of testing performance between individuals and is sometimes called “general intelligence”. Later on, psychologist Raymond Cattell determined that there are two subsets of g, called fluid intelligence (denoted Gf) and crystallized intelligence (denoted Gc). Fluid intelligence is defined as abstract reasoning or logic; it is an individual’s ability to solve a novel problem or puzzle. Crystalized intelligence is more knowledge based, and is defined as the ability to use one’s learned skills, knowledge, and experience (Cattell 1987). It is important to note that while c...
