Autistic spectrum disorder (ASD) is a neurodevelopmental characterized by deficits in social interactions, communication and stereotyped behaviour. Recent evidence from neuroimaging supports the hypothesis that ASD adults may be related to abnormalities specific frontal-temporal network [Autism-specific Structural Network (ASN)]. To see whether these results extend younger children better characterize abnormalities, we applied three morphometric methods on brain grey matter (GM) of with...

Individuals with autism spectrum disorder (ASD) are characterized by impairments in social communication and interaction. Although difficulties at processing signals from the face ASD have been observed emphasized for many years, there is a lot of inconsistency across both behavioral neural studies. We recorded scalp electroencephalography (EEG) 23 8-to-12 year old boys matched typically developing using fast periodic visual stimulation (FPVS) paradigm, providing objective (i.e.,...

We objectively quantified the neural sensitivity of school-aged boys with and without autism spectrum disorder (ASD) to detect briefly presented fearful expressions by combining fast periodic visual stimulation frequency-tagging electroencephalography. Images neutral faces were at 6 Hz, periodically interleaved 1.2 Hz oddball rate. While both groups equally display face inversion effect mainly rely on information from mouth expressions, ASD generally show reduced responses rapid changes in...

Background Difficulties with facial expression processing may be associated the characteristic social impairments in individuals autism spectrum disorder (ASD). Emotional face ASD has been investigated an abundance of behavioral and EEG studies, yielding, however, mixed inconsistent results. Methods We combined fast periodic visual stimulation (FPVS) to assess neural sensitivity implicitly detect briefly presented expressions among a stream neutral faces, 23 boys matched typically developing...

Abstract Atypical sensory processing is a core symptom of autism spectrum disorders (ASD). We aimed at better characterizing visual sensitivity and responsivity in ASD the self‐reported, behavioral neural levels, describing relationships between these levels. refer to as ability detect stimuli an affective response stimuli. Participants were 25 neurotypical 24 autistic adults. At self‐reported level, participants had higher scores than neurotypicals. The tasks involved contrast‐reversing...

Abstract Background Scanning faces is important for social interactions. Difficulty with the use of eye contact constitutes one clinical symptoms autism spectrum disorder (ASD). It has been suggested that individuals ASD look less at eyes and more mouth than typically developing (TD) individuals, possibly due to gaze aversion or indifference. However, eye-tracking evidence this hypothesis mixed. While patterns convey information about overt orienting processes, it unclear how manifested...

The ability to recognize faces and facial expressions is a common human talent. It has, however, been suggested be impaired in individuals with autism spectrum disorder (ASD). goal of this study was compare the processing identity emotion between ASD neurotypicals (NTs). Behavioural functional magnetic resonance imaging (fMRI) data from 46 young adults (aged 17–23 years, NASD = 22, NNT 24) analysed. During fMRI acquisition, participants discriminated short clips face transitioning neutral an...

Understanding social events requires assigning the participating entities to roles such as agent and patient, a mental operation that is reportedly effortless. We investigated whether, in processing visual scenes, role assignment accomplished automatically (i.e., when task does not require it), based on visuospatial information, without requiring semantic or linguistic encoding of stimuli. Human adults saw series images featuring same male female actors next each other, one an agentlike...

Individuals with autism spectrum disorder (ASD) have difficulties social communication and interaction. The motivation hypothesis states that a reduced interest in stimuli may partly underlie these difficulties. Thus far, however, it has been challenging to quantify individual differences orientation interest, pinpoint the neural underpinnings of it. In this study, we tested sensitivity for versus non-social information 21 boys ASD (8-12 years old) typically developing (TD) control boys,...

Abstract Difficulties in automatic emotion processing individuals with autism spectrum disorder (ASD) might remain concealed behavioral studies due to compensatory strategies. To gain more insight the mechanisms underlying facial recognition, we recorded eye tracking and mimicry data of 20 school‐aged boys ASD matched typically developing controls while performing an explicit recognition task. Proportional looking times specific face regions (eyes, nose, mouth) exploration dynamics were...

Abstract The neuropeptide oxytocin (OXT) is suggested to exert an important role in human social behaviors by modulating the salience of cues. To date, however, there mixed evidence whether a single dose OXT can improve behavioral and neural sensitivity for emotional face processing. overcome difficulties encountered with classic event‐related potential studies assessing stimulus‐saliency, we applied frequency‐tagging EEG implicitly assess effect (24 IU) on positive negative facial emotions....

Childhood adversity has been associated with alterations in threat-related information processing, including heightened perceptual sensitivity and attention bias towards threatening facial expressions, as well hostile attributions of neutral faces, although there is a large degree variability inconsistency reported findings. Here, we aimed to implicitly measure neural expression processing 120 adolescents between 12 16 years old (M = 13.93) without exposure childhood adversity. We combined...

Understanding a social event requires assigning the participating entities to roles such as agent and patient, mental operation that is reportedly effortless. We investigated whether, in processing visual scenes, role assignment accomplished automatically (i.e., when task does not require it), based on visuo-spatial information alone. Participants (male female human adults) saw series of images featuring same male actors next each other, one an agent-like (more dynamic, leaning forward)...

The social salience hypothesis proposes that the neuropeptide oxytocin (OT) can impact human behavior by modulating of cues. Here, frequency-tagging EEG was used to quantify neural responses versus non-social stimuli while administering a single dose OT (24 IU) placebo treatment. Specifically, two streams faces and houses were superimposed on one another, with each stream tagged particular presentation rate (i.e., 6 7.5 Hz or vice versa). These distinctive frequency tags allowed...

Fluently recognizing faces is crucial for social interactions. Impaired and atypical face processing have often been postulated as key deficits in autism spectrum disorders (ASD). Despite the great amount of research on ASD it still unclear which processes are impaired. This partly due to overreliance explicit tasks, may give an incomplete estimate spontaneous abilities ASD. To address this limitation, we apply innovative scalp electroencephalography approach combined with fast periodic...

Scanning faces is important for social interactions, and maintaining good eye contact carries significant value. Difficulty with the use of constitutes one clinical symptoms autism spectrum disorder (ASD). It has been suggested that individuals ASD look less at eyes more mouth than typically developing individuals, possibly due to gaze aversion (Tanaka & Sung, 2016) or indifference (Chevallier et al., 2012). Eye tracking evidence this hypothesis mixed (e.g. Falck-Ytter von Hofsten, 2011;...
