Abstract:

Schizophrenia is a neuropsychological disorder in which the neural systems which regulate attention allocation, primarily the dorsolateral prefrontal cortex, are dysfunctional, resulting in deficient gating of attention to irrelevant inputs from the environment. This sensory processing dysfunction hinders goal-directed behaviour to the extent that the subsequent cognitive deficits of schizophrenia prevent many chronic patients from leading normal lives. It is the onus of neuroscience to understand the nature of deficits induced by the disorder, thus providing target mechanisms for remediation

Abstract:

Over the past decade children have been facing increasingly large deficits towards their ability to pay attention. The inability to pay attention impacts children in every facet of their lives from focusing at school, in their home life, after school activities, etc. Inattention may impact children’s school performance, formation of social bonds, and the inability to pick up on appropriate social cues. Recently, more research has been conducted looking at attention processes in children and how they impact their daily functioning. However, a void lies in the treatments to help increase these d

Abstract:

Executive control is a vital cognitive function that facilitates the focussing and shifting of attention, planning and working towards a goal, ignoring distractions, and flexibly responding to novel situations. Disruptions to executive control are seen in many psychiatric and neurodegenerative disorders, as well as healthy ageing, which can be profoundly detrimental. Despite having many effective and well-validated methodologies for detecting and quantifying these deficits, there are very few treatments — pharmacological or otherwise — for ameliorating executive dysfunction. This lack of progr

Abstract:

Acceptance and Commitment Therapy (ACT) is a behaviorally-based intervention that promotes values-driven behavior change. ACT teaches skills such as acceptance, present-moment awareness, commitment to values-based actions, and new ways to interact with stressful and anxiety provoking thoughts and feelings. Mindfulness is a popular component of present moment awareness that is often taught within an ACT model of intervention. The purpose of this study was to determine if mindfulness alone or ACT could influence the psychological flexibility and attention of children with autism and related disa

Abstract:

Social interaction is an essential part of the human experience and actions are the primary means by which humans interact with the surrounding world. The ability to recognize and understand other people’s actions is necessary for an efficient interaction with other agents. Our motor system can promptly and accurately coordinate these forms of interactions in our daily activity. However, how the brain is able to produce such appropriate output has yet to be fully understood. The present work aims at unveiling the processes taking place in the motor system while observing actions of interactive

Abstract:

Le comportement normal d’un individu est le résultat de l’interaction entre les neurones, appelée la corrélation du bruit, qui se déroule en intra et inter les régions cérébrales. Cette corrélation joue un rôle important dans l’attention, la mémoire, la perception et la prise de décision. Plusieurs études ont montré qu’il y a une diminution de la corrélation du bruit pendant les processus d’apprentissage et que son augmentation est corrélée avec les échecs comportementaux. De ce fait, comprendre comment cette corrélation est ajustée en fonction des changements du comportement est très importan

Abstract:

Il est désormais bien établi que la flexibilité cognitive se développe fortement durant la période préscolaire (3-6 ans).

However, while offering an affordable account of how the human cognitive system works, these models appear too simplistic.
