Getting to know me better: An fMRI study of intimate and superficial self-disclosure to friends during adolescence.

ABSTRACT: Adolescence is often defined as a period of social reorientation, characterized by increased engagement with, and reliance on, same-aged peers. Consistent with these shifting motivations, we hypothesized that communicating information about oneself to friends would be intrinsically valued during adolescence. We specifically examined behavioral and neural differences when sharing information of varying depth in intimacy. These questions were investigated in a sample of early adolescent girls (N = 125, ages 10.0-13.0 years) who completed a self-disclosure monetary choice task while undergoing fMRI. Behaviorally, adolescents gave up more money to share superficial self-referential information than intimate self-referential information with a (real-life) close friend. Neural analyses identified extensive engagement of regions that support social cognition and emotion regulation when engaging in intimate self-disclosure. Behavioral and neural valuation of sharing superficial information were related to individual differences in self-worth and friendship quality. Comparatively, across all levels of analyses, adolescents were less likely to share intimate information. Findings highlight both the value and costs associated with self-disclosure during this time of increased peer sensitivity. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Project description:In recent years, the field of immunology has been revolutionized by the growing understanding of the fundamental role of microbiota in the immune system function. The immune system has evolved to maintain a symbiotic relationship with these microbes. The aim of our study was to know in depth the uncharacterized metagenome of the Buenos Aires (BA) city population and its metropolitan area, being the second most populated agglomeration in the southern hemisphere. For this purpose, we evaluated 30 individuals (age: 35.23 ± 8.26 years and BMI: 23.91 ± 3.4 kg/m2), from the general population of BA. The hypervariable regions V3-V4 of the bacterial 16S gene was sequenced by MiSeq-Illumina system, obtaining 47526 ± 4718 sequences/sample. The dominant phyla were Bacteroidetes, Firmicutes, Proteobacteria, Verrucomicrobia, and Actinobacteria. Additionally, we compared the microbiota of BA with other westernized populations (Santiago de Chile, Rosario-Argentina, United States-Human-microbiome-project, Bologna-Italy) and the Hadza population of hunter-gatherers. The unweighted UniFrac clustered together all westernized populations, leaving the hunter-gatherer population from Hadza out. In particular, Santiago de Chile's population turns out to be the closest to BA's, principally due to the presence of Verrucomicrobiales of the genus Akkermansia. These microorganisms have been proposed as a hallmark of a healthy gut. Finally, westernized populations showed more abundant metabolism related KEEG pathways than hunter-gatherers, including carbohydrate metabolism (amino sugar and nucleotide sugar metabolism), amino acid metabolism (alanine, aspartate and glutamate metabolism), lipid metabolism, biosynthesis of secondary metabolites, and sulfur metabolism. These findings contribute to promote research and comparison of the microbiome in different human populations, in order to develop more efficient therapeutic strategies for the restoration of a healthy dialogue between host and environment.
