Secular rise in economically valuable personality traits

2017

Although trends in many physical characteristics and cognitive capabilities of modern humans are well-documented, less is known about how personality traits have evolved over time. We analyze data from a standardized personality test administered to 79% of Finnish men born between 1962 and 1976 (n = 419,523) and find steady increases in personality traits that predict higher income in later life. The magnitudes of these trends are similar to the simultaneous increase in cognitive abilities, at 0.2-0.6 SD during the 15-y window. When anchored to earnings, the change in personality traits amounts to a 12% increase. Both personality and cognitive ability have consistent associations with famil…

Staging, neurocognition and social functioning in bipolar disorder.

2018

Introduction: Bipolar disorder (BD) is associated with significant neurocognitive and functional impairment, which may progress across stages. The ‘latent stage' of BD remains understudied. This cross-sectional study assessed staging, neurocognition and social functioning among BD patients and their healthy siblings.Methods: Four groups were included: euthymic type I BD patients in the early (n = 25) and late (n = 23) stages, their healthy siblings (latent stage; n = 23) and healthy controls (n = 21). All 92 subjects underwent a comprehensive neuropsychological battery of processing speed, verbal learning/memory, visual memory, working memory, verbal fluency, executive cognition, and motor …

El sexo, el contexto familiar y la actividad física extraescolar como factores asociados a la coordinación motriz en la niñez. Un estudio piloto. [Ge…

2019

Existen diversos factores que determinan el desarrollo y la evolución de la coordinación motriz. El presente estudio tiene por objetivo analizar la influencia del sexo, la actividad física practicada por los padres, la existencia de hermanos/as mayores o de igual edad y la práctica de actividad física extraescolar sobre el nivel de coordinación motriz global. La muestra estuvo compuesta por 23 niñas y 32 niños de entre 8-9 años (M = 8,51; DT = 0,31), pertenecientes al tercer curso de Educación Primaria. El nivel de coordinación motriz global de los estudiantes se valoró a través del Test Motor GRAMI-2 (Ruiz, Rioja, Graupera, Palomo, y García, 2015). El análisis de regresión lineal múltiple …

Children’s Emotions in Educational Settings: Teacher Perceptions from Australia, China, Finland, Japan and Spain

2019

The transition to formal education is a critical transition in children’s lives that has importance for socio-emotional and behavioral functioning. In the transition process, teachers are key players who work intensively with children and their families. This article focuses on teachers’ perceptions of children´s socio-emotional behavior during the transition from preschool to primary school. We collected qualitative teacher interviews from 112 teachers from five different countries—Australia, China, Finland, Japan and Spain. The research questions were: (1) How do teachers in the five countries perceive children’s abilities in expressing and regulating emotions. (2) How are children’s emot…

Data from: Growing up with feces: benefits of allo-coprophagy in families of the European earwig

2016

An important issue in the evolution of group living is the risk of pathogen and predator exposure entailed by the inherent accumulation of feces within a nesting site. While many group living species limit this risk by cleaning the nest, others do not, raising questions about the benefits of maintaining feces in the nest and their importance in social evolution. Here, we investigated whether one of these benefits could be mediated by coprophagy in families of the European earwig, Forficula auricularia. In this insect species, mothers and mobile juveniles (nymphs) line their nests with feces and consume them. In a first experiment, we tested whether access to feces produced by either nymphs …

Data from: Negative association between parental care and sibling cooperation in earwigs: a new perspective on the early evolution of family life?

2015

The evolution of family life requires net fitness benefits for offspring, which are commonly assumed to mainly derive from parental care. However, an additional source of benefits for offspring is often overlooked: cooperative interactions among juvenile siblings. In this study, we examined how sibling cooperation and parental care could jointly contribute to the early evolution of family life. Specifically, we tested whether the level of food transferred among siblings (sibling cooperation) in the European earwig Forficula auricularia (1) depends on the level of maternal food provisioning (parental care), and (2) is translated into offspring survival, as well as female investment into futu…

Data from: Sibling cooperation in earwig families provides insights into the early evolution of social life

2013

The evolutionary transition from solitary to social life is driven by direct and indirect fitness benefits of social interactions. Understanding the conditions promoting the early evolution of social life therefore requires identification of these benefits in nonderived social systems, such as animal families where offspring are mobile and able to disperse and will survive independently. Family life is well known to provide benefits to offspring through parental care, but research on sibling interactions generally focused on fitness costs to offspring due to competitive behaviors. Here we show experimentally that sibling interactions also reflect cooperative behaviors in the form of food sh…

A meta-analysis of temperament and character dimensions in patients with mood disorders: Comparison to healthy controls and unaffected siblings

2016

Background Cloninger's psychobiological model of personality has been extensively applied to subjects affected by mood disorders (MOOD). However, most studies are widely heterogeneous in terms of sample size, methods of assessment, and selection of participants. Methods We conducted a systematic review of literature and a random effects meta-analysis of studies comparing at least two of the following groups: (a) adults with a primary MOOD diagnosis (Bipolar Disorder (BP) or major depressive disorder (MDD)), (b) their unaffected siblings (SIB) or (c) healthy subjects (HS), and reporting quantitative results from the Tridimensional Personality Questionnaire (TPQ) or the Temperament and Charac…

LARP7 variants and further delineation of the Alazami syndrome phenotypic spectrum among primordial dwarfisms: 2 sisters.

2019

Abstract Alazami syndrome (AS) (MIM# 615071 ) is an autosomal recessive microcephalic primordial dwarfism (PD) with recognizable facial features and severe intellectual disability due to depletion or loss of function variants in LARP7. To date, 15 patients with AS have been reported. Here we describe two consanguineous Algerian sisters with Alazami PD due to LARP7 homozygous pathogenic variants detected by whole exome sequencing. By comparing these two additional cases with those previously reported, we strengthen the key features of AS: severe growth restriction, severe intellectual disability and some distinguishing facial features such as broad nose, malar hypoplasia, wide mouth, full li…
