To access the final edited and published work see 10.3389/fpsyg.2021.667603 The main objective of performance sport is to obtain achievements at the highest level through the adequate development of the athlete. The scientific literature demonstrates the fundamental role played by the inclusion of certain psychological variables in the training plan. This study examined the psychological profile of kayak polo players through the variables of burnou…
Associations between the dopamine D4 receptor gene polymorphisms and personality traits in elite athletes.
2019
Personality traits and temperament may affect sports performance. Previous studies suggest that dopamine may play an important role in behavior regulation and physical exercise performance. The aim of this study is to determine associations between dopamine D4 receptor gene (DRD4 Ex3) polymorphisms and personality traits (such as neuroticism, extraversion, openness, agreeability and conscientiousness) in elite combat athletes. A total of 302 physically active, unrelated, self-reported Caucasian participants were recruited for this study. The participants consisted of 200 elite male combat athletes and 102 healthy male participants (control group). For personality trait measurements, the NEO…
Toddlers’ understanding of basic emotions: identification, labeling and causality / La comprensión temprana de las emociones básicas: identificación,…
2014
AbstractThe aim of this paper is to explore the early acquisition pattern of the understanding of basic emotions. Many studies indicate that three-year-old children identify emotions such as joy or sadness, but it is not known how this knowledge arises. Fifty-seven boys and girls between 21 and 32 months were assessed using the Brunet-Lezine-R developmental scale (BL-R) (Josse, 1997) and the Affective knowledge Test (AKT) (Denham, 1986). Through this test we evaluated the children’s knowledge of four basic emotions (happiness, sadness, anger and fear) in three of its components (identification, causality and linguistic labeling). In order to track knowledge acquisition longitudinally, a sma…
Measuring music-induced emotion: A comparison of emotion models, personality biases, and intensity of experiences
2011
Most previous studies investigating music-induced emotions have applied emotion models developed in other fields to the domain of music. The aim of this study was to compare the applicability of music-specific and general emotion models – namely the Geneva Emotional Music Scale (GEMS), and the discrete and dimensional emotion models – in the assessment of music-induced emotions. A related aim was to explore the role of individual difference variables (such as personality and mood) in music-induced emotions, and to discover whether some emotion models reflect these individual differences more strongly than others. One hundred and forty-eight participants listened to 16 film music excerpts a…
A functional MRI study of happy and sad emotions in music with and without lyrics
2011
Musical emotions, such as happiness and sadness, have been investigated using instrumental music devoid of linguistic content. However, pop and rock, the most common musical genres, utilize lyrics for conveying emotions. Using participants’ self-selected musical excerpts, we studied their behavior and brain responses to elucidate how lyrics interact with musical emotion processing, as reflected by emotion recognition and activation of limbic areas involved in affective experience. We extracted samples from subjects’ selections of sad and happy pieces and sorted them according to the presence of lyrics. Acoustic feature analysis showed that music with lyrics differed from music without lyric…
Fifty shades of blue : Classification of music-evoked sadness
2016
It has been repeatedly shown that sad music induces mainly pleasant or mixed emotions, and is particularly relevant for self-regulation goals. However, this is not entirely compatible with the view that sadness is one of the basic emotions experienced in the face of an unpleasant event or a loss. Also, a distinction between grief and sadness is often drawn, which seemingly does not have relevance in relation to musical experiences. The discrepancy between the positive accounts of emotions associated with sad music and those present in ordinary sadness may be related to the previously unacknowledged spectrum of affects associated with music-related sadness. The present study aims to expose t…
Sex-specific selection on energy metabolism - selection coefficients for winter survival
2010
Selection for different fitness optima between sexes is supposed to operate on several traits. As fitness-related traits are often energetically costly, selection should also act directly on the energetics of individuals. However, efforts to examine the relationship between fitness and components of the energy budget are surprisingly scarce. We investigated the effects of basal metabolic rate (BMR, the minimum energy required for basic life functions) and body condition on long-term survival (8 winter months) with manipulated densities in enclosed populations of bank voles (Myodes glareolus). Here, we show that survival selection on BMR was clearly sex-specific but density-independent. Both…
Individual differences in behavioral consistency are related to sequential access to resources and body condition in a producer-scrounger game
2014
Investigating the evolution of consistent between-individual behavioral differences necessitates to explain the emergence of within-individual consistency. Relying on a recent mathematical model, we here test the prediction that the emergence of differences in within-individual consistency is related to the sequential access to resources in a frequency-dependent foraging game. To this end we used flocks of zebra finches (Taeniopygia guttata) engaged in a producer-scrounger foraging game. Tactic investment (i.e., the proportion of hops with the head down) significantly predicted successful tactic use (i.e., the proportion of seeds produced). In support of predictions, we found that individua…
Gene expression patterns associated with caste and reproductive status in ants: worker-specific genes are more derived than queen-specific ones.
2013
Variation in gene expression leads to phenotypic diversity and plays a central role in caste differentiation of eusocial insect species. In social Hymenoptera, females with the same genetic background can develop into queens or workers, which are characterized by divergent morphologies, behaviours and lifespan. Moreover, many social insects exhibit behaviourally distinct worker castes, such as brood-tenders and foragers. Researchers have just started to explore which genes are differentially expressed to achieve this remarkable phenotypic plasticity. Although the queen is normally the only reproductive individual in the nest, following her removal, young brood-tending workers often develop …
La inserción laboral de los inmigrantes italianos en Valencia durante la crisis
2018
España ha pasado de una fase de intensa inmigración internacional durante el período de crecimiento económico a otra de re-emigración y retornos de extranjeros (y de emigración de nativos) durante la recesión. En nuestra investigación hemos observado una tendencia opuesta: durante la crisis se ha incrementado significativamente la llegada de inmigrantes procedentes de Italia a la ciudad de Valencia. Se trata de personas económicamente activas, con intención de permanencia, cualificadas y procedentes de regiones con indicadores socioeconómicos superiores a los de la Comunidad Valenciana. Por consiguiente, el análisis de su inserción laboral es clave para explicar las causas de la migración. …
