Structure of Dark Triad Dirty Dozen Across Eight World Regions.

The Dark Triad (i.e., narcissism, psychopathy, Machiavellianism) has garnered intense attention over the past 15 years. We examined the structure of these traits' measure-the Dark Triad Dirty Dozen (DTDD)-in a sample of 11,488 participants from three W.E.I.R.D. (i.e., North America, Oceania, Western Europe) and five non-W.E.I.R.D. (i.e., Asia, Middle East, non-Western Europe, South America, sub-Saharan Africa) world regions. The results confirmed the measurement invariance of the DTDD across participants' sex in all world regions, with men scoring higher than women on all traits (except for psychopathy in Asia, where the difference was not significant). We found evidence for metric (and partial scalar) measurement invariance within and between W.E.I.R.D. and non-W.E.I.R.D. world regions. The results generally support the structure of the DTDD.

Agentic narcissism, communal narcissism, and prosociality.

Grandiose narcissism and prosociality are important topics in personality and social psychology, but research on their interplay is lacking. We present a first large-scale, systematic, and multimethod investigation linking the two. In 2 studies (N1 = 688, N2 = 336), we assessed grandiose narcissism comprehensively (i.e., agentic and communal narcissism) and examined its relations with instantiations of prosociality, namely, objective prosociality (actual behavior in Study 1; round-robin informant-reports in a real-life setting in Study 2) and subjective prosociality (self-perceptions in Studies 1 and 2). We obtained a consistent set of results. Agentic narcissism was related to lower objective prosociality and lower subjective prosociality. Communal narcissism, by contrast, was unrelated to objective prosociality, but was related to higher subjective prosociality. Additionally, we tested for prosociality self-enhancement among agentic and communal narcissists. Agentic narcissists evinced the same (and modest) level of prosociality self-enhancement as their non-narcissistic counterparts. Communal narcissists, by contrast, evinced substantial levels of prosociality self-enhancement, whereas their non-narcissistic counterparts did not enhance their prosociality at all. We discuss implications of the findings for the literature on narcissism and antisociality, and for the concept of prosocial personality.

Individual self > relational self > collective self-But why? Processes driving the self-hierarchy in self- and person perception.

OBJECTIVE: The self has three parts: individual, relational, and collective. Typically, people personally value their individual self most, their relational self less, and their collective self least. This self-hierarchy is consequential, but underlying processes have remained unknown. Here, we propose two process accounts. The content account draws upon selves' agentic-communal content, explaining why the individual self is preferred most. The teleology account draws upon selves' instrumentality for becoming one's personal ideal, explaining why the collective self is preferred least. METHOD: In Study 1 (N = 200, 45% female, Mage = 32.9 years, 79% Caucasian), participants listed characteristics of their three selves (individual, relational, collective) and evaluated those characteristics in seven preference tasks. Additionally, we analyzed the characteristics' agentic-communal content, and participants rated their characteristics' teleological instrumentality. Study 2 (N = 396, 55% female, Mage = 34.5 years, 76% Caucasian) used identical methodology and featured an additional condition, where participants evaluated the selves of a friend. RESULTS: Study 1 reconfirmed the self-hierarchy and supported both process accounts. Study 2 replicated and extended findings. As hypothesized, when people evaluate others' selves, a different self-hierarchy emerges (relational > individual > collective). CONCLUSIONS: This research pioneers process-driven explanations for the self-hierarchy, establishing why people prefer different self-parts in themselves than in others.

Mind-Body Practices and the Self: Yoga and Meditation Do Not Quiet the Ego but Instead Boost Self-Enhancement.

Mind-body practices enjoy immense public and scientific interest. Yoga and meditation are highly popular. Purportedly, they foster well-being by curtailing self-enhancement bias. However, this "ego-quieting" effect contradicts an apparent psychological universal, the self-centrality principle. According to this principle, practicing any skill renders that skill self-central, and self-centrality breeds self-enhancement bias. We examined those opposing predictions in the first tests of mind-body practices' self-enhancement effects. In Experiment 1, we followed 93 yoga students over 15 weeks, assessing self-centrality and self-enhancement bias after yoga practice (yoga condition, n = 246) and without practice (control condition, n = 231). In Experiment 2, we followed 162 meditators over 4 weeks (meditation condition: n = 246; control condition: n = 245). Self-enhancement bias was higher in the yoga (Experiment 1) and meditation (Experiment 2) conditions, and those effects were mediated by greater self-centrality. Additionally, greater self-enhancement bias mediated mind-body practices' well-being benefits. Evidently, neither yoga nor meditation fully quiet the ego; to the contrary, they boost self-enhancement.

Developmental regulation of presence of binding sites for neoglycoproteins and endogenous lectins in various embryonic stages of human lung, liver and heart.

Protein-carbohydrate interactions are supposed to play key roles in the mechanisms of cell adhesion, biosignalling and intracellular routing, warranting the analysis of the developmental course of expression of epitopes of this system. Thus, a panel of carrier-immobilized carbohydrate ligands was used as probes, namely lactose,N-acetylgalactosamine,N-acetylglucosamine, mannose, fucose and maltose. Additionally, an antibody to an endogenous ß-galactoside-binding lectin (anti-galectin-1), the biotinylated lectin and two further human lectins, namely the macrophage migration inhibitory factor-binding sarcolectin and serum amyloid P component (SAP) that displays selectivity for sulphated sugars and mannose-6-phosphate, were included. They enabled us to assess the extent of the presence of respective binding sites in fixed sections from human lungs (pulmonary epithelial cells), livers (hepatocytes) and hearts (myocard cells) of 10-50 weeks gestation. Invariably, specific binding was detected in the three organ types, at least in certain stages. In most of the cases, the intensity of staining exhibited developmental regulation. The apparent patterns reveal similarities between the different cell types, as seen with immobilizedN-acetylglucosamine as well as with labelled galectin-1 and sarcolectin. However, drastic differences among such patterns with nearly opposite developmental courses do also occur, as detected for carrier-attached mannose and maltose residues. These results point to a potential importance for the detected glycohistochemical features in human development and substantiate the possibility of differential regulation of the presence of binding sites for distinct sugars within a certain organ and between the individual cell types of the monitored organs.
