The Neural Mechanisms Of Conformity Across Socioeconomic Status And Development Abstract Social influence is omnipresent, explicitly and implicitly influencing people’s preferences and behaviors. Recently, neuroscientists have begun to contribute to our understanding of social influence, providing insight into mental processes that occur in real time without the need for participant introspection. The current dissertation aims to build our understanding of social influence yb examining the neural mechanism that underlie receiving feedback about others’ preferences, as well as the mechanisms that underlie conformity to others’ preferences. In order to examine these relationships, the current dissertation examined four questions. First, we examined which neural mechanisms underlie processing social feedback and conformity across 249 people, making it the largest study of social influence in the brain to date. Next, we examined whether SES (high versus low) moderates neural mechanisms associated with social influence processing and conformity. Third, we examined whether development (adolescents versus young adults) moderates neural mechanisms associated with social influence. Finally, we examined whether the relationship between SES and social influence processing and conformity is different depending on developmental trajectories. Results from the current dissertation provide robust evidence for a core set of brain systems involved in conflict detection and mentalizing that are implicated in social influence across groups. We address previous methodological limitations stemming from diverse methods employed to study social influence across different past studies of influence. In addition, we begin ot show evidence that socio-demographic factors and development may moderate the neural bases of social influence. akT en together the findings from the current dissertation advance our understanding of social influence yb providing evidence for a set of core mechanisms involved in social influence. eW do not find obustr evidence for differences in neural processing associated with socio-demographic factors, but highlight some subtle differences and discuss possibilities for future neuroimaging research that can more definitively address commonalities and differences across groups.

Cascio Emily B. Falk Social influence is omnipresent, explicitly and implicitly influencing people’s preferences and behaviors. Recently, neuroscientists have begun to contribute to our understanding of social influence, providing insight into mental processes that occur in real time without the need for participant introspection. The current dissertation aims to build our understanding of social influence by examining the neural mechanism that underlie receiving feedback about others’ preferences, as well as the mechanisms that underlie conformity to others’ preferences. In order to examine these relationships, the current dissertation examined four questions. First, we examined which neural mechanisms underlie processing social feedback and conformity across 249 people, making it the largest study of social influence in the brain to date. Next, we examined whether SES (high versus low) moderates neural mechanisms associated with social influence processing and conformity. Third, we examined whether development (adolescents versus young adults) moderates neural mechanisms associated with social influence. Finally, we examined whether the relationship between SES and social influence processing and conformity is different depending on developmental trajectories. Results from the current dissertation provide robust evidence for a core set of brain systems involved in conflict detection and mentalizing that are implicated in social influence across groups. We address previous methodological limitations stemming from diverse methods employed to study social influence across different past studies of influence. In addition, we begin to show evidence that socio-demographic factors and development may moderate the neural bases of social influence. Taken together the findings from the current dissertation advance our understanding of social influence by providing evidence for a set of core mechanisms involved in social influence. We do not find robust evidence for iv differences in neural processing associated with socio-demographic factors, but highlight some subtle differences and discuss possibilities for future neuroimaging research that can more definitively address commonalities and differences across groups. v TABLE OF CONTENTS ACKNOWLEDGMENT .................................................................................................... iii ABSTRACT ..................................................................................................................... iv LIST OF TABLES ........................................................................................................... vii LIST OF ILLUSTRATIONS ........................................................................................... viii CHAPTER 1.

Hechtmana, Hannah Railab, Joan Y. Chiaoa, & June Gruberb a Northwestern University, Evanston, IL b Yale University, New Haven, CT Abstract There is burgeoning interest in the study of positive emotion regulation and psychopathology. Given the significant public health costs and the tremendous variance in national prevalence rates associated with many disorders of positive emotion, it is critical to reach an understanding of how cultural factors, along with biological factors, mutually influence positive emotion regulation. Progress in this domain has been relatively unexplored, however, underscoring the need for an integrative review and empirical roadmap for investigating the cultural neuroscientific contributions to positive emotion disturbance for both affective and clinical science domains. The present paper thus provides a multidisciplinary, cultural neuroscience approach to better understand positive emotion regulation and psychopathology. We conclude with a future roadmap for researchers aimed at harnessing positive emotion and alleviating the burden of mental illness cross-culturally. © Copyright 2013 Textrum Ltd.

This marriage of the two previously unconnected areas of inquiry has generated a variety of empirical and theoretical works that have provided unique insights to both partners that might have otherwise gone overlooked. Here, I provide a brief historical introduction to the emergence of cultural neuroscience from its roots in cultural psychology and cognitive neuroscience to its present stature as one of the most challenging but rewarding sub-disciplines to have come from the burgeoning growth of the study of the brain and behavior. In doing so, I overview some of the more studied areas within cultural neuroscience: language, music, mathematics, visual perception, and social cognition.

  • Advancing the Study of Cultural Evolution: Academic Integration and Policy Applications Description of Conceptual Framework
    Advancing the Study of Cultural Evolution: Academic Integration and Policy Applications A workshop held at the University of Maryland College Park Campus March 19th and 20th, 2015 Organizers: Michele Gelfand and David Sloan Wilson Description of Conceptual Framework and Workshop Sessions 1 A Conceptual Framework for the Study of Cultural Evolution The study of genetic evolution has had over a century and a half to mature. The mechanisms of human cultural evolution evolved by genetic evolution and qualify as an evolutionary process in their own right. The study of cultural evolution may therefore make use of the same conceptual framework that has been developed for the study of genetic evolution. Our workshop was organized with this possibility in mind, while also leaving room for discussing the merits of other conceptual frameworks. Session 1: The proximate/ultimate distinction and Tinbergen’s four questions Evolutionary theory draws heavily on the distinction between ultimate and proximate causation (Mayr 1959), which notes that all products of evolution require two explanations: 1) Why a given trait exists, compared to many other traits that could exist (ultimate causation); and 2) How a given trait exists in a physical sense (proximate causation). Niko Tinbergen (1963) independently stressed four questions that need to be asked for all products of evolution, concerning function, phylogeny, mechanism, and development. Tinbergen’s fourfold distinction adds a temporal dimension to Mayr’s two-fold distinction, such that ultimate causation explains the nature of adaptations and the history of their evolution, while proximate causation explains the physical basis of traits and their development during the lifetime of the organism.

  • 1 Introduction: the Evolution of Culture in a Microcosm
    1 Introduction: The Evolution of Culture in a Microcosm Stephen C. Levinson Evolutionary speculation constitutes a kind of metascience, which has the same intellectual fascination for some biologists that metaphysical speculation possessed for some medieval scholastics. It can be considered a relatively harmless habit, like eating peanuts, unless it assumes the form of an obsession; then it becomes a vice. —R. V. Stanier, Some aspects of the biology of cells in H. Charles and B. Knight (eds.), Organization and Control in Prokaryotic Cells As the quotation here suggests, this volume is full of the vice of speculation. Yet any student of the human condition can hardly avoid it. Somehow culture—or at least the culture-bearing ape—evolved. An evolutionary perspective on human culture, which is much less fashionable now than it was 70 or more years ago, seems inevitable, yet the social sciences actively resist it, allowing ill-informed conjectures from other sci- ences (which does little to increase the interest from the social sciences of course). In this introductory chapter, I try to do two things: The first is to deal frontally, and speculatively, with what I take to be the “big questions” about the evolution of human culture. This may serve as a partial introduction to the more detailed explo- rations in other chapters in this volume. The second is to give the reader some grist for these speculative mills. I will argue that if we look at the details of any culture, it is quite clear that we need an evolutionary perspective to understand how such fea- tures could have arisen (note that such a perspective is quite consistent with other kinds of social science explanations).

This new field links cross– cultural psychology with cognitive neuroscience across fundamental domains of cognitive and social psychology. We present a summary of studies on emotion, perspective-taking, memory, object perception, attention, language, and the self, showing cultural differences in behavior as well as in neural activation. Although it is still nascent, the broad impact of merging the study of culture with cognitive neuroscience holds mutual distributed benefits for mul- tiple related fields.

  • An Introduction to Cultural Neuroscience Lyndac.Linandevah.Telzer
    An Introduction to Cultural Neuroscience LyndaC.LinandEvaH.Telzer This chapter’s goal is to serve as a brief introduction to the emerging feld of cultural neuroscience. It does not intend to provide an extensive review but rather a brief overview of the feld. We start by defning cultural neu- roscience and follow by providing important reasons for doing research in this feld. Next we explain some key terms and methodologies. We then highlight important studies in the feld and provide recommendations for designing a study. Finally, we make suggestions for future directions. Throughout this chapter, we choose a few specifcexamplestoillustrate ways in which cultural neuroscience researchers have utilized the concepts and tools described here. What Is Cultural Neuroscience? Cultural neuroscience is an emerging interdisciplinary feld that combines theories and methods from cultural and social psychology, anthropology, and social and cognitive neuroscience to investigate the interactions between culture, psychological processes, brain, and genes at diferent timescales (for reviews, see Chiao, Cheon, Pornpattananangkul, Mrazek, & Blizinsky, 2013; Han et al., 2013; Kim & Sasaki, 2014). Because of the broad interdisciplinary nature of the feld, describing all of the diferent ways in which cultural neuroscientists do research in this area is beyond the scope of this chapter. Here we will be focusing on the most common method, which is representations in the brain through neuroimaging techniques. Because this feld lies at the intersection of many areas of study, we begin by describing how cultural neuroscience derives from each of these The Handbook of Culture and Biology,FirstEdition.EditedbyJose´ M.

  • The Contribution of Cultural Neuroscience to Cultural Psychiatry Vittorio De Luca
    Editorial The contribution of cultural neuroscience to cultural psychiatry Vittorio De Luca The issue that our readers are about to read is a real source of pride for the Editorial Board, because it focuses on a fundamental topic for our discipline. Indeed, the aim of this issue is to underscore the centrality of cultural psychiatry as the branch of human science capable to create a specific synergy between neuroscience and psychiatry in order to set up a new epistemological toolbox for the study of mental health. The hybridization between neuroscience, representing the most “scientific” hard core of technological civilizations, and cultural psychiatry, promoting a more “flexible” method based on comparisons, promises to hopefully connect data from these two different sources of knowledge: on the one hand the study of biological roots of brain functioning; the study of the cultural context promoting or enhancing psychic expressions, on the other one, no matter whether these are considered normative or pathological by the cultural community, the patient’s entourage, or the psychiatric nosography currently in use. This is the reason that the last World Congress has been entitled “Cultural brain and living societies”, and also that a plenary session, a thematic symposium and a video conference were devoted to the discipline of cultural neuroscience. Today’s issue offers some interventions presented at the conference, enriched by the latest knowledge and by more systematic and analytical data and references, in order to provide readers an overall conceptual basis with state of the art of several research fields in this domain. The first contribution comes from the Italian group led by Liborio Stuppia in Chieti, and offers an essential overview of recent advance in the relationship between genetics and environment, and the devolpment of some specific aspects of human mental functioning, including intelligence.

Environment, Culture, and the Brain 75 Kirsten Brukamp Neurohistory: Being in Time What is neurohistory?—The ambitious endeavors suggested by the novel term pos- sess the potential to result in unexpected perspectives on both history and neurosci- ence. Neurohistory projects fall into one of three categories. Focus on history: Neurohistory may first be history informed by neuroscience. Ac- cordingly, neuroscience is here understood as a support for achieving historical un- derstanding: historical events and processes are assessed in light of insights from neuroscience. Examples for projects in this field comprise all those that would benefit from a deeper understanding of individual actions, collective intentions, and social behaviors—that is, goals that may be reached with psychology as well as social and cultural neuroscience (Adolphs 2009; Rizzolatti and Sinigaglia 2010; Martinez Mateo et al. 2011). In particu- lar, research can unearth new perspectives on gender differences, personal factors in history, conflicts, conflict resolution, hierarchy, and power structures. In select cases, the behavior of influential individuals may be explained by disorders of the nervous system (Toole 1995). For prehistory, comparative biology and neuroscience could identify distinct stages of behavior and culture in the evolution of human ancestors (Stout et al.
