Abstract Background Previous studies have reported a negative psychological and mental health impact of the COVID-19 pandemic. This is likely to be stronger for people with autism as they are at heightened risk problems because pandemic directly affects social functioning everyday routines. We therefore examined pandemic-related changes in health, on their life routines, satisfaction information tips, participants’ wishes guidance. Methods used mixed-method approach, collecting quantitative...

Objective: Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with performance deficits across a broad range of tasks.While individual tasks are designed to tap specific cognitive functions (e.g., memory, inhibition, planning, etc.) these could also reflect general effects related either inefficient or impulsive information processing both.These two components cannot be isolated from each other on the basis classical analysis in which mean reaction time (RT) and accuracy handled...

The present study investigates the association of parenting and family factors with nonsuicidal self-injury (NSSI) in preadolescents. A sample 1,439 preadolescents their parents were assessed by means (a) adolescent-reported behaviors (support behavioral/psychological control), (b) parent-reported control) stress, (c) structure, socioeconomic status (SES) family, functioning, stressful life-events. prevalence NSSI was 4.82%. Preadolescents engaging perceived more psychological behavioral...

Investigating the underlying neural mechanisms of autism spectrum disorder ( ASD ) has recently been influenced by discovery mirror neurons. These neurons, active during both observation and execution actions, are thought to play a crucial role in imitation other social‐communicative skills that often impaired . In current electroencephalographic study, we investigated mu suppression, indicating mirroring children with between ages 24 48 months age‐matched typically developing children,...

The state regulation deficit model posits that individuals with attention-deficit/hyperactivity disorder (ADHD) have difficulty applying mental effort effectively under suboptimal conditions such as very fast and slow event rates (ERs).ADHD is also associated diminished suppression of default mode network (DMN) activity related performance deficits on tasks requiring effortful engagement.The current study builds these two literatures to test the hypothesis failure modulate DMN in ADHD might...

There is extensive discussion on whether spontaneous and explicit forms of ToM are based the same cognitive/neural mechanisms or rather reflect qualitatively different processes. For first time, we analyzed BOLD signal for false belief processing by directly comparing task versions. In both versions, participants watched videos a scene including an agent who acquires true about location object (belief formation phase). At end movies (outcome phase), had to react presence object. During...

There has been debate over whether disruptions in the mirror neuron system (MNS) play a key role core social deficits observed autism spectrum disorders (ASD). EEG mu suppression during observation of biological actions is believed to reflect MNS functioning, but understanding developmental progression and rhythm both typical atypical development lacking. To provide more thorough direct exploration individuals with ASD, sample 66 ASD 51 typically developing 6–17 years old were pooled from...

The goal of the present study was to shed light on respective contributions three important action monitoring brain regions (i.e. cingulate cortex, insula, and orbitofrontal cortex) during conscious detection response errors. To this end, fourteen healthy adults performed a speeded Go/Nogo task comprising Nogo trials varying levels difficulty, designed elicit aware unaware Error awareness indicated by participants with second key press after target press. Meanwhile, electromyogram (EMG) from...

The socio-communicative difficulties of individuals with autism spectrum disorder (ASD) are hypothesized to be caused by a specific deficit in the ability represent one's own and others' mental states, referred as Theory Mind or mentalizing. However, many ASD show successful performance on explicit measures mentalizing, for this reason, is thought better captured spontaneous While there initial behavioral support hypothesis, mentalizing has not yet been studied at neural level. Recent...

Theory of mind (ToM) research has shown that adults with high functioning autism (HFA) demonstrate typical performance on tasks require explicit belief reasoning, despite clear social difficulties in everyday life situations. In the current study, we used implicit manipulations are task-irrelevant and therefore less susceptible to strategies. a ball-detection task, it was neurotypical individuals detect ball faster if an agent believed present. We predicted would not show this effect. While...

Recent theories propose that autism is characterized by an impairment in determining when to learn and not. We investigated this estimating learning rate environments varying volatility uncertainty. Specifically, we correlated autistic traits (in 163 neurotypical participants) with modelled behaviour during probabilistic reward under the following three conditions: a Stationary Low Noise condition stable contingencies, Volatile changing contingencies High where probabilities for all options...
