Communicative skills in Spanish children with Autism Spectrum Disorder and children with Attention Deficit Hyperactivity Disorder. Analysis through p…

2018

Background Communicative skills are one of the main deficits experienced by children with Autism Spectrum Disorder (ASD). The differential diagnosis is a complex issue that clinicians often face. For this reason, this study has two objectives: 1) to analyze the similarities and differences that children with Attention Deficit Hyperactivity Disorder (ADHD) and children with ASD present in their linguistic and communicative skills, through parentś perceptions and narrative production; 2) to identify the relative importance of the skills analyzed in discriminating children with ASD versus children with ADHD, as well as the classification power of each of the two measurement methods used.

Volcanic risk and the role of the media. A case study in the Etna area

2019

On December 24, 2018, the Etna volcano has recorded a significant eruption. Linked to this phenomenon, after a seismic swarm of 72 shocks, a 4.8-magnitude earthquake struck a large area North of Catania city, on the Eastern coast of Sicily. Six villages reported 28 injured people and damages to the building. According to seismologists the earthquake had an unusual level of magnitude. Yet, despite the real danger of this event, many people who live around the volcano, in one of the most densely populated areas of Sicily, perceived these facts in an ambivalent way. Indeed, their lives continued as before even in awareness of the natural hazard, while several media presented the situation as r…

Artificial faces predict gaze allocation in complex dynamic scenes

2019

Both low-level physical saliency and social information, as presented by human heads or bodies, are known to drive gaze behavior in free-viewing tasks. Researchers have previously made use of a great variety of face stimuli, ranging from photographs of real humans to schematic faces, frequently without systematically differentiating between the two. In the current study, we used a Generalized Linear Mixed Model (GLMM) approach to investigate to what extent schematic artificial faces can predict gaze when they are presented alone or in competition with real human faces. Relative differences in predictive power became apparent, while GLMMs suggest substantial effects for real and artificial f…

Mental fatigue induced by prolonged self-regulation does not exacerbate central fatigue during subsequent whole-body endurance exercise

2015

International audience; It has been shown that the mental fatigue induced by prolonged self-regulation increases perception of effort and reduces performance during subsequent endurance exercise. However, the physiological mechanisms underlying these negative effects of mental fatigue are unclear. The primary aim of this study was to test the hypothesis that mental fatigue exacerbates central fatigue induced by whole-body endurance exercise. Twelve subjects performed 30 min of either an incongruent Stroop task to induce a condition of mental fatigue or a congruent Stroop task (control condition) in a random and counterbalanced order. Both cognitive tasks (CTs) were followed by a whole-body …

Processus sensoriels cognitifs et comportementaux impliqués dans la perception des mélanges odorants alimentaires complexes chez le lapin nouveau-né …

2015

Within each breath, a large diversity of volatiles molecules of the surrounding reaches our olfactory receptors. Despite the chemical complexity of the natural environment, the organisms succeed to represent their world using relevant information carried by single odorants or mixtures. Focusing on the perception of these stimuli, we explored the processes involved in the treatment of this complex information, sometimes supported by mixtures or sub-mixtures. The treatment is based on two processes: the elemental mode, which allows extracting the odor quality of all or some of the elements, or the configural mode which allows the holistic representation of the mixture. In this doctoral thesis…

Perceptual contents : a study on the nature of the contents of perceptual experience

2013

The aim of the thesis is to examine various views that have been advocated in contemporary discussions concerning the content of perceptual experiences. The nature of the contents posited in those views is the focus of this study. In the views that are discussed here, perceptual contents have been argued to be either conceptual, externalist, nonconceptual or particular. In this thesis, John McDowell is presented as the proponent of conceptual content, Jeff Speaks as the proponent of externalist content, Christopher Peacocke as the proponent of abstract nonconceptual contents, and Tim Crane as the proponent of particular nonconceptual content. The revised view of John McDowell, as well as th…

Perception des adventices par les agriculteurs, conseillers, techniciens d’expérimentation et chercheurs en France

2019

Une enquête nationale ayant recueilli 1320 réponses (839 analysées dans cet article), dont 56% d'agriculteurs, 26% de conseillers, 14% de techniciens/expérimentateurs et 4% de chercheurs, a permis de sonder leur perception des adventices. Les effets positifs des adventices ont moins d’importance aux yeux des sondés que leurs effets négatifs. Pour les effets négatifs, la perte de rendement (nuisibilité primaire directe) et l’augmentation du stock semencier (nuisibilité secondaire) sont les plus importants. Entre 60% et 80% des personnes enquêtées jugent importants les effets négatifs sur la conduite des travaux agricoles et la perte de qualité la récolte. Les effets positifs « sources de pol…

Numerical Magnitude Affects Accuracy but Not Precision of Temporal Judgments

2021

A Theory of Magnitude (ATOM) suggests that space, time, and quantities are processed through a generalized magnitude system. ATOM posits that task-irrelevant magnitudes interfere with the processing of task-relevant magnitudes as all the magnitudes are processed by a common system. Many behavioral and neuroimaging studies have found support in favor of a common magnitude processing system. However, it is largely unknown whether such cross-domain monotonic mapping arises from a change in the accuracy of the magnitude judgments or results from changes in precision of the processing of magnitude. Therefore, in the present study, we examined whether large numerical magnitude affects temporal ac…
