Sport burnout inventory–Dual career form for student-athletes: Assessing validity and reliability in a Finnish sample of adolescent athletes
2020
Background: The pressure of pursuing an athletic career simultaneously with education may set adolescent student-athletes at risk for sport and school burnout. Although the 2 life domains of student-athletes are strongly intertwined, so far, there has not been an instrument for investigating sport burnout parallel to school burnout. The aim of the present study was to introduce a sport burnout measure for adolescents in a dual career context and investigate its validity and reliability by using confirmatory factor analysis. Methods: The participants were 391 student-athletes (51% females) who filled in a questionnaire of sport burnout and background variables in the beginning of upper secon…
Are There Lower Repetition Priming Effects in Children with Developmental Dyslexia? Priming Effects in Spanish with the Masked Lexical Decision Task.
2016
The aim of this study was to compare the reaction times and errors of Spanish children with developmental dyslexia to the reaction times and errors of readers without dyslexia on a masked lexical decision task with identity or repetition priming. A priming paradigm was used to study the role of the lexical deficit in dyslexic children, manipulating the frequency and length of the words, with a short Stimulus Onset Asynchrony (SOA = 150 ms) and degraded stimuli. The sample consisted of 80 participants from 9 to 14 years old, divided equally into a group with a developmental dyslexia diagnosis and a control group without dyslexia. Results show that identity priming is higher in control childr…
Sports, Executive Functions and Academic Performance: A Comparison between Martial Arts, Team Sports, and Sedentary Children
2021
It is well known that curricular physical activity benefits children’s executive functions and academic performance. Therefore, this study aimed to determine whether there is an influence of extracurricular sports on executive functions and academic performance. However, it is less known which specific types of the sport better enhance executive functions in children
Age differences in the role of the cannabinoid type 1 receptor on glutamatergic neurons in habituation and spatial memory acquisition
2015
Abstract Aims Aging is typically linked with a decline in memory performance and alterations in neural integrity. In pathological aging such as Alzheimer's disease, these effects are aggravated. Studies using cannabinoid CB1 receptor-deficient mice have shown a role of the endocannabinoid system in memory processing and neuroprotection. As the CB1 receptor is expressed in various neuronal populations, in this study, we aimed at investigating the consequences of CB1 receptor gene inactivation in cortical glutamatergic neurons in mice (Glu-CB1-KO) in regard to age-related alterations in spatial memory performance. Main methods Juvenile (5.5–7.5 weeks), adult (5.5–7 months), and old (11.5–14 m…
The oral lipid sensor GPR120 is not indispensable for the orosensory detectionof dietary lipids in the mouse
2014
International audience; Implication of the long-chain fatty acid (LCFA) receptor GPR120, also termed free fatty acid receptor 4 (FFAR4), in the taste-guided preference for lipids is a matter of debate. To further unravel the role of GPR120 in the "taste of fat", the present study was conducted on GPR120-null mice and their wild-type littermates. Using a combination of morphological (i.e. immunohistochemical staining of circumvallate papillae - CVP), behavioral (i.e. two-bottle preference tests, licking tests and conditioned taste aversion) and functional studies (i.e. calcium imaging in freshly isolated taste bud cells - TBC), we show that absence of GPR120 in oral cavity was not associated…
Alcohol preference, behavioural reactivity and cognitive functioning in female rats exposed to a three-bottle choice paradigm.
2012
Alcohol abuse is a substantial and growing health problem in Western societies. In the last years in vivo and in vitro studies have suggested that males and females display a different alcohol drinking behaviour, with swingeing differences not only in the propensity for alcohol use but also in the metabolic and behavioural consequences. In this study we investigated, in adult female rats, ethanol self-administration and preference pattern using a 3-bottle paradigm with water, 10% ethanol solution, and white wine (10%, v/v), along a four-week period. The influence of alcohol free-access on explorative behaviour in the open field (OF), and on spatial learning and reference memory in the Morri…
Got rhythm… for better and for worse. Cross-modal effects of auditory rhythm on visual word recognition
2013
The present research aimed to investigate whether, as previously observed with pictures, background auditory rhythm would also influence visual word recognition. In a lexical decision task, participants were presented with bisyllabic visual words, segmented into two successive groups of letters, while an irrelevant strongly metric auditory sequence was played in a loop. The first group of letters could either be congruent with the syllabic division of the word (e.g. val in val/se) or not (e.g. va in va/lse). In agreement with the Dynamic Attending Theory (DAT), our results confirmed that the presentation of the correct first syllable on-beat (i.e. in synchrony with a peak of covert attentio…
Social and motivational functioning is not critically dependent on feedback of autonomic responses: neuropsychological evidence from patients with pu…
2004
Social, emotional and motivational behaviours are associated with production of automatic bodily responses. Re-representation in the brain through feedback of autonomic and skeletomuscular arousal is proposed to underlie "feeling states". These influence emotional judgments and bias motivational decision-making and guide social interactions. Consistent with this hypothesis, dissocial behaviour and deficits on emotional and motivation tasks are associated with blunted bodily responses in patients with orbitofrontal brain lesions or developmental psychopathy. To determine the critical dependence of social and emotional behaviours on bodily responses mediated by the autonomic nervous system, w…
Does Tonal Information Affect the Early Stages of Visual-Word Processing in Thai?
2014
Thai offers a unique opportunity to investigate the role of lexical tone processing during visual-word recognition, as tone is explicitly expressed in its script. In order to investigate the contribution of tone at the orthographic/phonological level during the early stages of word processing in Thai, we conducted a masked priming experiment—using both lexical decision and word naming tasks. For a given target word (e.g., ห้อง/hᴐ:ŋ2/, room), five priming conditions were created: (a) identity (e.g., ห้อง/hᴐ:ŋ2/), (b) same initial consonant, but with a different tone marker (e.g., ห่อง/hᴐ:ŋ1/), (c) different initial consonant, but with the same tone marker (e.g., ศ้อง/sᴐ:ŋ2/), (d) orthograph…
Does Top-Down Feedback Modulate the Encoding of Orthographic Representations During Visual-Word Recognition?
2016
Abstract. In masked priming lexical decision experiments, there is a matched-case identity advantage for nonwords, but not for words (e.g., ERTAR-ERTAR < ertar-ERTAR; ALTAR-ALTAR = altar-ALTAR). This dissociation has been interpreted in terms of feedback from higher levels of processing during orthographic encoding. Here, we examined whether a matched-case identity advantage also occurs for words when top-down feedback is minimized. We employed a task that taps prelexical orthographic processes: the masked prime same-different task. For “same” trials, results showed faster response times for targets when preceded by a briefly presented matched-case identity prime than when preceded by …
