The role of the behavioral immune system in the expression of short and long-term orientation in young Chilean men during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic drastically changed people's lives. It had consequences at the individual and social level. The behavioral immune system predicts that when faced with the risk of contagion from pathogens, people tend to reduce their sociality, especially sociosexuality.

Phenotype of severe tricuspid regurgitation induced by intracardiac pacing devices.

Introduction And Aims: Tricuspid regurgitation (TR) induced by the implantation of cardiac implantable electronic devices (CIED) is an increasingly common cause of severe TR. Our aim was to describe the echocardiographic phenotypic characteristics of CIED-induced severe TR.

Methods: Retrospective cohort study that included patients with severe TR related to CIED diagnosed in the cardiac imaging unit of a Spanish tertiary hospital.

Translating the behaviour change technique taxonomy version 1 into Spanish: Methodology and validation.

Background: Precise and unequivocal specification of intervention content is key to facilitating the accumulation and implementation of knowledge. The Behaviour Change Technique Taxonomy v1 (BCTTv1) is the most widely used classification of behaviour change techniques (BCTs), providing a shared, standardized vocabulary to identify the active ingredients of behavioural interventions. However, the BCTTv1 is only available in English and this hampers its broad use and adoption.

Quantitative evaluation of a theoretical-conceptual model based on affective and socio-behavioral dimensions to explain the academic performance of mathematics students.

Objective: There is evidence that suggests that affective dimensions, personality traits, as well as students' cooperative interpersonal interactions, are an important element in the students learning process. In this work we propose a theoretical model, based on evidence, that shows the direct and indirect relationships between these factors and academic performance in mathematics courses, in undergraduate and school students.

Methods: To understand the type of relationships between these variables, the PANAS psychometric test of positive and negative affect, the BIG FIVE personality test and the economic decision game DUPLES GAME were applied.

The effect of intergroup competition outcome on ingroup cooperation: insights from the male warrior hypothesis.

Introduction: The Male Warrior Hypothesis (MWH) proposes that sex-specific selective pressures have promoted male cooperation with the ingroup members to outcompete rival groups. However, intergroup conflicts do not occur in isolation and the outcomes of previous competitions may influence group cooperativeness. Since this phenomenon is not well understood, we aimed to shed light on the effect of previous competition outcome on later cooperative behavior under intergroup conflicts.
