L’utilisation des mécanismes de maintien de l’information verbale en mémoire de travail chez l’enfant de 8 ans
2010
La mémoire de travail est une forme de mémoire immédiate qui permet de retenir des informations tout en effectuant simultanément un traitement sur ces informations ou sur d’autres informations. Elle est indispensable dans la vie quotidienne, par exemple sans elle nous serions incapable de comprendre une phrase ou de résoudre une opération. Les informations stockées dans cette mémoire ne peuvent être maintenues que pendant un très bref instant (± 2 secondes). Cependant, il est possible de les retenir pendant une plus longue durée en utilisant des mécanismes de maintien. Actuellement deux mécanismes de maintien ont été mis en évidence. Le premier est un mécanisme de répétition subvocale, qui …
The effect of alertness and attention on the modulation of the beta rhythm to tactile stimulation
2021
Abstract Beta rhythm modulation has been used as a biomarker to reflect the functional state of the sensorimotor cortex in both healthy subjects and patients. Here, the effect of reduced alertness and active attention to the stimulus on beta rhythm modulation was investigated. Beta rhythm modulation to tactile stimulation of the index finger was recorded simultaneously with MEG and EEG in 23 healthy subjects (mean 23, range 19–35 years). The temporal spectral evolution method was used to obtain the peak amplitudes of beta suppression and rebound in three different conditions (neutral, snooze, and attention). Neither snooze nor attention to the stimulus affected significantly the strength of…
Project DyAdd : Nonlinguistic theories of dyslexia predict intelligence
2020
Two themes have puzzled the research on developmental and learning disorders for decades. First, some of the risk and protective factors behind developmental challenges are suggested to be shared and some to be specific for a given condition. Second, language-based learning difficulties like dyslexia are suggested to result from or correlate with also nonlinguistic aspects of information processing. In the current study, we investigated how adults with developmental dyslexia and ADHD as well as healthy controls cluster across various dimensions designed to tap the prominent nonlinguistic theories of dyslexia. Participants were 18–55-year-old adults with dyslexia (n = 36), ADHD (n = 22), and…
Extended-release guanfacine hydrochloride in 6-17-year olds with ADHD: a randomised-withdrawal maintenance of efficacy study.
2015
Background Extended-release guanfacine hydrochloride (GXR), a selective α2A-adrenergic agonist, is a nonstimulant medication for attention-deficit/hyperactivity disorder (ADHD). This phase 3, double-blind, placebo-controlled, randomised-withdrawal study evaluated the long-term maintenance of GXR efficacy in children/adolescents with ADHD. Methods Children/adolescents (6–17 years) with ADHD received open-label GXR (1–7 mg/day). After 13 weeks, responders were randomised to GXR or placebo in the 26-week, double-blind, randomised-withdrawal phase (RWP). The primary endpoint was the percentage of treatment failure (≥50% increase in ADHD Rating Scale version IV total score and ≥2-point increase …
A Human-Humanoid Interaction Through the Use of BCI for Locked-In ALS Patients Using Neuro-Biological Feedback Fusion.
2018
This paper illustrates a new architecture for a human–humanoid interaction based on EEG-brain computer interface (EEG-BCI) for patients affected by locked-in syndrome caused by Amyotrophic Lateral Sclerosis (ALS). The proposed architecture is able to recognise users’ mental state accordingly to the biofeedback factor $\text {B}_{\text f}$ , based on users’ attention, intention, and focus, that is used to elicit a robot to perform customised behaviours. Experiments have been conducted with a population of eight subjects: four ALS patients in a near locked-in status with normal ocular movement and four healthy control subjects enrolled for age, education, and computer expertise. The results s…

Familiarity changes as a function of perceptual shifts.
2010
This experiment compares the yes-no and forced recognition tests as methods of measuring familiarity. Participants faced a phase of 3 study-test recognition trials in which they studied words using all the letters of the alphabet (overlapping condition, O), and an additional phase in which targets and lures did not share any letters (non-overlapping condition, NO). Finally, subjects performed a forced-choice task in which they had to choose one of two new words, each from one of the subsets (Parkin et al., 2001). Results in the NO condition higher than .50, showing their sensitivity to familiarity. When the letter set of the words for study in the third list of the NO condition was swit…
La rigenerazione urbana delle periferie degradate: il caso emblematico della città di Palermo
2020
Il saggio esamina le nuove tendenze della legislazione in materia di rigenerazione urbanistica, con particolare attenzione alla vicenda urbanistica del Comune di Palermo.
2014
Some years ago an improved design (the "complete design") was proposed to assess the composite face effect in terms of a congruency effect, defined as the performance difference for congruent and incongruent target to no-target relationships (Cheung et al., 2008). In a recent paper Rossion(2013) questioned whether the congruency effect was a valid hallmark of perceptual integration, because it may contain confounds with face-unspecific interference effects. Here we argue that the complete design is well-balanced and allows one to separate face-specific from face-unspecific effects. We used the complete design for a same/different composite stimulus matching task with face and non-face objec…
Incidencia de la experiencia docente con el TDAH en los conocimientos, la autoeficacia y los niveles de estrés docente
2020
Los estudios que han comparado los conocimientos que tienen los profesores sin experiencia (PSE) y los profesores con experiencia profesional (PCE) sobre el Trastorno por Déficit de Atención e Hiperactividad (TDAH) han mostrado resultados contradictorios. Además, el papel que tiene la experiencia docente con niños con TDAH sobre los conocimientos, la autoeficacia y el estrés docente no ha sido abordado en los estudios previos. Por ello, el presente estudio pretende: a) comparar los conocimientos, las creencias erróneas y las lagunas de conocimiento de los PCE y PSE de España, acerca del TDAH; b) analizar la experiencia de los PCE con niños con TDAH y la relación con los conocimientos, la au…
