Do large‐scale associations in birds imply biotic interactions or environmental filtering?
2023
Aim There has been a wide interest in the effect of biotic interactions on species' occurrences and abundances at large spatial scales, coupled with a vast development of the statistical methods to study them. Still, evidence for whether the effects of within-trophic-level biotic interactions (e.g. competition and heterospecific attraction) are discernible beyond local scales remains inconsistent. Here, we present a novel hypothesis-testing framework based on joint dynamic species distribution models and functional trait similarity to dissect between environmental filtering and biotic interactions. Location France and Finland. Taxon Birds. Methods We estimated species-to-species association…
Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validat…
2023
Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reliability of those predictions, they need to be critically validated with respect to what they are used for. While ecologists are typically interested in how and where distributions will change, we argue that SDMs have seldom been evaluated in terms of their capacity to predict such change. Instead, typical retrospective validation methods estimate model's ability to predict to only one static time in future. Here, we apply two validation methods, one that predicts and evaluates a static pattern, while the other measures change…

Depression and Violence in Adolescence and Young Adults: Findings From Three Longitudinal Cohorts
2017
Objective Despite recent research demonstrating associations between violence and depression in adults, links in adolescents are uncertain. This study aims to assess the longitudinal associations between young people’s depression and later violent outcomes. Method We used data from three cohorts with different measurements of depression exposures and subsequent violent outcomes. In a Dutch community cohort Research on Adolescent Development And Relationships (RADAR; N = 623) and a population-based British birth cohort Avon Longitudinal Study of Parents and Children (ALSPAC; N = 4,030), we examined the longitudinal links between adolescent depressive symptoms and violent behaviors from age 1…
Experiencing anger in a social interaction: The role of personality
2018
Abstract Although prior research has shown a relationship between the Big Five personality factors and trait anger, evidence that links these personality traits to the experience of state anger is rare. The current study investigated the effect of the Big Five personality traits on the state anger experience after a provocation in a staged social interaction and how status differences moderate these personality effects in an academic sample. In the equal status condition (N = 131, 56% female, aged 18 to 37) participants were provoked by a confederate; in the low status condition (N = 125, 55% female, aged 18 to 51) anger was instead provoked by the experimenter. In both conditions, individu…
Students’ multiple state goals as a function of appraisals, trait goals, and their interactions
2017
Abstract Although many motivational theories have emphasized that person- and situation-based aspects should be recognized simultaneously when explaining actual learning behavior, not much is known about the occurrence of state goals. The model of adaptive learning (Boekaerts & Niemivierta, 2000) proposes that state goals are influenced by trait goals, perceptions of the situation (i.e., appraisals), and interactions between trait goals and appraisals. Nevertheless, empirical evidence for this model is scarce. The present study aimed to overcome this research deficit by integrating trait goals and appraisals as well as their interactions in explaining state goals in authentic learning episo…
The Impact of Personality and Motivation on Immersion in Simulation Games
2020
The cognitive-motivational process model of learning describes how personality traits in a specific situation influence current learner motivation and through certain mediators, the learning outcome. This study investigates the influence of personality traits and current motivation on these mediators. For 86 high school students playing a simulation game, the Big Five, the need for cognition, current motivations, immersion, and joy of learning were measured. A hierarchical regression analysis showed that need for cognition, interest, and challenge significantly and positively impacts the experienced immersion. Also, the joy of learning correlates positively with immersion. The adapted model…
Funcionamiento familiar, personalidad y satisfacción vital en las parejas casadas
2017
Abstract.FAMILY FUNCTIONING, PERSONALITY AND LIFE SATISFACTION IN MARRIED COUPLESTheory and research suggest that the personality characteristics that each spouse brings to a relationship are related to marital and life satisfaction. Furthermore, a variety of studies have shown that Emotional Stability, Agreeableness, and Conscientiousness are strongly related to relationship satisfaction, which in turn benefits spouses’ satisfaction with life in general. Regarding family functioning, familial cohesion, defined as the degree of togetherness or closeness or emotional bonding that family members have toward one another, was found to be correlated with inter-personal well-being and satisfactio…
Examining the Veggiee Personality: Results from a Representative German Sample
2017
An increasing proportion of people choose to follow a vegetarian diet. To date, however, little is known about if and how individual differences in personality relate to following a vegetarian diet. In the two studies presented here, we aimed to (1) estimate the prevalence of self-defined vegetarians in two waves of a German representative sample (N = 4,496 and 5,125, respectively), (2) analyze the effect of socio-demographic variables on dietary behavior, and (3) examine individual differences between vegetarians and meat eaters in personality traits, political attitudes, and health-related variables. In Study 1, a strict definition of vegetarians was used, while in Study 2 the definition …
Personality predicts social dominance in female zebra finches, Taeniopygia guttata, in a feeding context.
2011
6 pages; International audience; Although personality has been defined as a suite of correlated behaviours, most studies of animal personality actually consider correlations between a few traits. We examined the repeatability and correlational structure of five potential personality traits (activity, neophobia, exploratory tendencies, risk-taking behaviour and obstinacy), in female zebra finches. In addition, we assessed to what extent personality influenced social dominance in a feeding context in this gregarious species. All personality traits were found to be highly repeatable within individuals. In addition, except for obstinacy, all of them were related to each other, thus defining a b…
