My grade, my right: linking academic entitlement to academic performance

The identifcation of determinants and correlates of academic entitlement is of particular interest for researchers and (academic) tutors alike. Whilst personality traits have been linked to academic entitlement in the past, the relative importance of familial influence remains unclear. Hence, to address this deficit, this study utilizes a sample of business and psychology undergraduates (N=170) in the United Arab Emirates. Additionally, the impact of academic entitlement on students’ misestimation of coursework grades was assessed in a subsample of psychology undergraduates (N=92). Multiple regression analyses revealed honesty–humility as the strongest predictor of academic entitlement, indicating lower entitlement of more honest students. In contrast, familial influences were unrelated to academic entitlement. Interestingly, higher entitled expectations were associated with larger overestimation of grades. Our findings indicate honesty–humility as an important driver of academic entitlement, whilst entitled expectations appear to be associated with misperceptions of students' own academic performance

Probing the strength of infants' preference for helpers over hinderers: two replication attempts of Hamlin and Wynn (2011)

Several studies indicate that infants prefer individuals who act prosocially over those who act antisocially toward unrelated third parties. In the present study, we focused on a paradigm published by Kiley Hamlin and Karen Wynn in 2011. In this study, infants were habituated to a live puppet show in which a protagonist tried to open a box to retrieve a toy placed inside. The protagonist was either helped by a second puppet (the “Helper”), or hindered by a third puppet (the “Hinderer”). At test, infants were presented with the Helper and the Hinderer, and encouraged to reach for one of them. In the original study, 75% of 9-month-olds selected the Helper, arguably demonstrating a preference for prosocial over antisocial individuals. We conducted two studies with the aim of replicating this result. Each attempt was performed by a different group of experimenters. Study 1 followed the methods of the published study as faithfully as possible. Study 2 introduced slight modifications to the stimuli and the procedure following the guidelines generously provided by Kiley Hamlin and her collaborators. Yet, in our replication attempts, 9-month-olds’ preference for helpers over hinderers did not differ significantly from chance (62.5% and 50%, respectively, in Studies 1 and 2). Two types of factors could explain why our results differed from those of Hamlin and Wynn: minor methodological dissimilarities (in procedure, materials, or the population tested), or the effect size being smaller than originally assumed. We conclude that fine methodological details that are crucial to infants’ success in this task need to be identified to ensure the replicability of the original result

Photoelectron circular dichroism of O 1ss-photoelectrons of uniaxially oriented trifluoromethyloxirane: Energy dependence and sensitivity to molecular configuration

The photoelectron circular dichroism (PECD) of the O 1s-photoelectrons of trifluoromethyloxirane(TFMOx) is studied experimentally and theoretically for different photoelectron kinetic energies. The experiments were performed employing circularly polarized synchrotron radiation and coincidentelectron and fragment ion detection using Cold Target Recoil Ion Momentum Spectroscopy. The corresponding calculations were performed by means of the Single Center method within the relaxed-core Hartree-Fock approximation. We concentrate on the energy dependence of the differential PECD of uniaxially oriented TFMOx molecules, which is accessible through the employed coincident detection. We also compare results for differential PECD of TFMOx to those obtained for the equivalent fragmentation channel and similar photoelectron kinetic energy of methyloxirane (MOx), studied in our previous work. Thereby, we investigate the influence of the substitution of the methyl-group by the trifluoromethyl-group at the chiral center on the molecular chiral response. Finally, the presently obtained angular distribution parameters are compared to those available in literature.Comment: 6 fig

Pervasiveness of the IQ Rise: A Cross-Temporal Meta-Analysis

Background: Generational IQ gains in the general population (termed the Flynn effect) show an erratic pattern across different nations as well as across different domains of intelligence (fluid vs crystallized). Gains of fluid intelligence in different countries have been subject to extensive research, but less attention was directed towards gains of crystallized intelligence, probably due to evidence from the Anglo-American sphere suggesting only slight gains on this measure. In the present study, development of crystallized intelligence in the German speaking general population is assessed. Methodology/Principal Findings: To investigate whether IQ gains for crystallized intelligence are in progress in Germanspeaking countries, two independent meta-analyses were performed. By means of a cited reference search in ISI Web of Science, all studies citing test manuals and review articles of two widely-used salient measures of crystallized intelligence were obtained. Additionally, the electronic database for German academic theses was searched to identify unpublished studies employing these tests. All studies reporting participants mean IQ or raw scores of at least one of the two measures were included in the present analyses, yielding over 500 studies (.1,000 samples;.45,000 individuals). We found a significant positive association between years of test performance and intelligence (1971–2007) amounting to about 3.5 IQ points per decade. Conclusions/Significance: This study clearly demonstrates that crystallized IQ gains are substantial and of comparabl

GWAS meta-analysis reveals novel loci and genetic correlates for general cognitive function : a report from the COGENT consortium

CORRIGENDUM Molecular Psychiatry (2017) 22, 1651–1652 http://www.nature.com/articles/mp2017197.pdfThe complex nature of human cognition has resulted in cognitive genomics lagging behind many other fields in terms of gene discovery using genome-wide association study (GWAS) methods. In an attempt to overcome these barriers, the current study utilized GWAS meta-analysis to examine the association of common genetic variation (similar to 8M single-nucleotide polymorphisms (SNP) with minor allele frequency >= 1%) to general cognitive function in a sample of 35 298 healthy individuals of European ancestry across 24 cohorts in the Cognitive Genomics Consortium (COGENT). In addition, we utilized individual SNP lookups and polygenic score analyses to identify genetic overlap with other relevant neurobehavioral phenotypes. Our primary GWAS meta-analysis identified two novel SNP loci (top SNPs: rs76114856 in the CENPO gene on chromosome 2 and rs6669072 near LOC105378853 on chromosome 1) associated with cognitive performance at the genome-wide significance level (PPeer reviewe

Sex differences in the adult human brain:Evidence from 5216 UK Biobank participants

Sex differences in the human brain are of interest for many reasons: for example, there are sex differences in the observed prevalence of psychiatric disorders and in some psychological traits that brain differences might help to explain. We report the largest single-sample study of structural and functional sex differences in the human brain (2750 female, 2466 male participants; mean age 61.7 years, range 44–77 years). Males had higher raw volumes, raw surface areas, and white matter fractional anisotropy; females had higher raw cortical thickness and higher white matter tract complexity. There was considerable distributional overlap between the sexes. Subregional differences were not fully attributable to differences in total volume, total surface area, mean cortical thickness, or height. There was generally greater male variance across the raw structural measures. Functional connectome organization showed stronger connectivity for males in unimodal sensorimotor cortices, and stronger connectivity for females in the default mode network. This large-scale study provides a foundation for attempts to understand the causes and consequences of sex differences in adult brain structure and function

Alternativen zu Säuglingsnahrungen auf Kuhmilchproteinbasis

Die natürliche Ernährung eines gesunden Säuglings ist das Stillen. Ist Stillen oder die Fütterung von Muttermilch nicht möglich, kann Frauenmilch für die Ernährung des Säuglings erwogen werden, sofern diese aus einer qualifizierten Humanmilchbank stammt. Vom Kauf von Frauenmilch aus dem Internet wird wegen Risiken einer Infektionsübertragung und einer unzureichenden Milchqualität strikt abgeraten. Aufgrund der geringen Verfügbarkeit, der hohen Kosten sowie möglicher Nachteile der Ernährung mit Spendermilch im Vergleich zum Stillen sind industriell gefertigte Säuglingsnahrungen das Mittel der Wahl zur Ernährung des gesunden, reifgeborenen Säuglings, wenn Stillen nicht oder nur partiell möglich ist. Kuhmilchprotein ist die am häufigsten verwendete Eiweißkomponente. Die Nachfrage nach anderen auf Tiermilchen basierten sowie vegetarischen bzw. veganen Alternativen steigt. Im Folgenden werden verschiedene Alternativen bezüglich ihrer Eignung betrachtet. Säuglingsnahrungen auf Basis von Ziegenmilchprotein stellen für gesunde, reifgeborene Säuglinge eine zugelassene und geeignete Alternative zu kuhmilchproteinbasierten Säuglingsnahrungen dar. Für Säuglingsnahrungen aus anderen Tiermilchen (z. B. Kamel‑, Schaf‑, Pferde- oder Büffelmilch) sind keine belastbaren Daten zu Eignung und Sicherheit bekannt, und sie sind in der Europäischen Union nicht zugelassen. Säuglingsnahrungen auf der Grundlage von Sojaproteinisolaten sind in der Europäischen Union zugelassen. Sie werden für die allgemeine Verwendung im 1. Lebenshalbjahr durch die Ernährungskommission nicht empfohlen, insbesondere weil potenziell nachteilige Effekte von enthaltenen Isoflavonen nicht ausgeschlossen werden können. Ab der Geburt und in den ersten Lebensmonaten sollte die Gabe von Sojanahrungen auf Indikationen wie eine bestehende Galaktosämie, die sehr seltene kongenitale Laktoseintoleranz sowie bei familiärem Wunsch nach veganer Ernährungsweise und aus anderen weltanschaulichen Gründen begrenzt werden. Im 2. Lebenshalbjahr ist die Zufuhrmenge pro Kilogramm Körpergewicht deutlich niedriger, sodass das Risiko unerwünschter Wirkungen als wesentlich geringer eingeschätzt wird. Zu neuerdings angebotenen Nahrungen auf der Grundlage einer Mischung aus Soja- und Kuhmilchprotein sind keine Daten zur Prüfung von Sicherheit und Eignung bekannt, sodass hierzu keine Empfehlung ausgesprochen werden kann. Von der Verwendung von Säuglingsnahrung auf der Grundlage von hydrolysiertem Reisprotein wird auch aufgrund hoher berichteter Arsengehalte abgeraten. Auch von einer häuslichen Selbstherstellung von Säuglingsnahrungen wird aufgrund eines erhöhten Risikos für eine nichtbedarfsgerechte Nährstoffzufuhr und für Infektionen abgeraten. // The natural nutrition of a healthy infant is breastfeeding. If breastfeeding or feeding of breast milk is not possible, feeding of donor human milk may be considered. The safety of donor milk can only be ensured if it is provided by a qualified human milk bank. The use of informally shared donor milk or the use of human milk purchased through the internet is strongly discouraged because of the risk of transmitting infections and of insufficient milk quality. Due to low availability, high costs and concerns about poorer nutritional quality of donor milk compared to breastfeeding, industrially manufactured infant formula is the preferred alternative for feeding healthy full-term infants that cannot or cannot be fully breastfed. Milk-based infant formula is most frequently made from cow’s milk protein; however, there is an increasing popularity of vegetarian or vegan formulas and of formulas based on different animal milks other than cow’s milk. Goat’s milk-based infant formulas represent an approved and suitable alternative to cow’s milk for healthy, full-term infants. Reliable data on the suitability and safety are unavailable for formulas based on other animal milks (e.g., camel, horse, sheep or buffalo milk), and these are not approved for infant feeding in the European Union. Infant formulas based on soybean protein isolates are approved in the European Union. They are not generally recommended by the Nutrition Committee for infant feeding in the first half year of life because potentially harmful effects of isoflavones derived from soybeans cannot be excluded; however, soybean protein isolate-based formulas may be reservedly used after birth and in the first months of life for infants affected by galactosemia, the very rare hereditary lactose intolerance manifest at birth, a vegan family lifestyle or other familial convictions. In the second half year of life the intake amount per kilogram body weight is much less so that the risk of undesired effects is estimated to be much lower. For the recently provided nutrition based on a mixture of soybean and cow’s milk proteins, no data on testing of the safety and suitability are known, so that no recommendations can be made on this. The use of infant formula based on hydrolyzed rice protein is not recommended because of concerns about possible high arsenic contamination. The use of homemade infant formulas is discouraged due to the high risk of introducing infections and of possible nutritional imbalances of macronutrients and micronutrients

Body appreciation around the world: Measurement invariance of the Body Appreciation Scale-2 (BAS-2) across 65 nations, 40 languages, gender identities, and age.

The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research.
