Background: Affectivity has been suggested as a complex adaptive meta-system composed of positive affect and negative affect, two independent but interrelated markers of well-being, that can be represented as four distinct affective profiles: self-fulfilling (high positive affect/low negative affect), high affective (high positive affect/high negative affect), low affective (low positive affect/lo
Humanity has long battled mosquitoes and the diseases they transmit—a struggle intensified by climate change and globalization, which have expanded mosquito ranges and the spread of associated diseases.1 Additionally, widespread insecticide resistance has reduced the efficacy of current control methods, necessitating new solutions.2,3 Nootkatone, a natural compound found in grapefruit, shows promi
Legislatures are a key institution in modern political systems. They control the executive: in parliamentary systems, they elect the government, and in presidential systems, they often approve the members of the cabinet who were appointed by the president. Moreover, legislatures and their committees are the main bodies in a political system in which new policies - in the form of law proposals - ar
Episodic memories are not static - they shift and reshape as our surroundings evolve. One powerful mechanism for change are prediction errors, which arise when predictions about what is going to happen next do not match the actual input. This study investigated how the size of prediction errors - arising from predictions based on episodic memories - affects recognition memory and neural memory rep
Analogical reasoning is a form of non-deductive reasoning that gives special weight to similarity considerations. Here, we pursue an approach to formalizing this type of reasoning that was initiated by Carnap in posthumously published work. In it, Carnap abandoned his long-time project of trying to define inductive and analogical reasoning syntactically and introduced attribute spaces to model the
Objective: Although patients prefer describing their problems using words, mental health interventions are commonly evaluated using rating scales. Fortunately, recent advances in natural language processing (i.e., AI-methods) yield new opportunities to quantify people's own mental health descriptions. Our aim was to explore whether responses to open-ended questions, quantified using AI, provide ad
Climate mitigation constitutes an intergenerational moral dilemma; the decisions we make today will inevitably shape the prospects for generations to come. Yet, we still know little about the relationship between intergenerational altruism (IGA)—our concerns for the well-being of future generations—and support for costly climate mitigation policies. In this study, we present an approach to measuri
Background Gender discrimination of women is often emphasized in work contexts, whereas less focus is on how men are discriminated against in social relationships. Gender discrimination in decisions of family relations, is essential to study as the contact between parent and child is commonly viewed as the most important relationship in people’s life, as well as being the most important aspect of
Rating scales are the dominating tool for the quantitative assessment of mental health. They are often believed to have a higher validity than language-based responses, which are the natural way of communicating mental states. Furthermore, it is unclear how difficulties articulating emotions-alexithymia-affect the accuracy of language-based communication of emotions. We investigated whether narrat
Psychological constructs are commonly quantified with closed-ended rating scales. However, recent advancements in natural language processing (NLP) enable the quantification of open-ended language responses. Here we demonstrate that descriptive word responses analyzed using NLP show higher accuracy in categorizing emotional states compared to traditional rating scales. One group of participants (N
Studies show that genetics matter in who becomes a leader. However, we know little about the dynamic properties of the heritability of leadership emergence or how genetics might interact with environmental conditions to shape leadership emergence. We track leadership role occupancy at three time points among a cohort of 1,079 Danish twin pairs over ten years. Our results suggest that genetics matt
In two studies, we examined if correct and incorrect statements in eyewitness testimony differed in semantic content. Testimony statements were obtained from participants who watched staged crime films and were interviewed as eyewitnesses. We analyzed the latent semantic representations of these statements using LSA and BERT. Study 1 showed that the semantic space of correct statements differed fr
Radical right populist parties have often been treated as “pariahs,” being excluded from coalition politics in parliamentary democracies. We argue that negative rhetoric targeted at radical right populist parties in legislative debates is used by the established parties to distance themselves from such parties and that the incentives to do so depend on the political context. Using sentiment analys
Recent research suggests that to help their preferred coalition win an election, voters are willing to vote for a political party other than their preferred choice. In this field, voting for smaller parties under proportional representation is an under-studied feature. A crucial factor to estimate the chances for smaller parties is polls. In this study, we analyze the influence of opinion polls on
It has been established across several contexts that political attitudes are informed by heritable factors. However, it remains unclear how much of the stability we observe in political attitudes can be ascribed to environmental factors and how much of the stability is due to genetics. In this paper we show, using a unique three-wave panel dataset of twins (N = 2471) spanning ten years, that both
We present an exact dimensionality reduction for dynamics of an arbitrary array of globally coupled complex-valued Riccati equations. It generalizes the Watanabe-Strogatz theory [Integrability of a globally coupled oscillator array, Phys. Rev. Lett. 70, 2391 (1993).PRLTAO0031-900710.1103/PhysRevLett.70.2391] for sinusoidally coupled phase oscillators and seamlessly includes quadratic integrate-and
This study explores how rising economic costs of climate mitigation policies differentially shape climate policy support among the political left and right. To this end, we randomly manipulate how much consumption costs increase as a result of four different climate mitigation policies and study how different cost scenarios influence policy support among a sample of 1,597 Swedish adults. We find t
Background: Happiness is often conceptualized as subjective well-being, which comprises people's evaluations of emotional experiences (i.e., the affective dimension: positive and negative feelings and emotions) and judgements of a self-imposed ideal (i.e., the cognitive dimension: life satisfaction). Recent research has established these two dimensions as primary parts of a higher order factor. Ho
Scholarly literature has demonstrated that hybridity transforms both legacy and new media, but that this change is not even. We treat social media platforms as arenas of remediation, where users share and add their own context to information produced by both media subtypes and compare social media conversations about migration in six European languages that include links to either traditional or n
