Background: Despite increasing knowledge of social communication skills of autistic peole, the interrelatedness of different skills such as non-linguistic comprehension, social inference and empathizing skills is not much known about. A better understanding of the complex interplay between different domains of social communication helps us to develop assessment protocols for individuals with social communication difficulties.

Aims: To compare the performances of autistic young adults, young adults with autistic traits identified in childhood and control young adults in social communication tasks measuring non-linguistic comprehension, social inference and empathizing skills.

Previous social-pragmatic and narrative research involving autistic individuals has mostly focused on children. Little is known about how autistic adults and adults who have autistic traits but do not have a diagnosis of an autism spectrum disorder (ASD) interpret complex social situations and tell narratives about these situations. We asked 32 autistic young adults, 18 adults with autistic traits but no ASD diagnosis, and 34 non-autistic young adults to watch socially complex situations and freely tell narratives about what they thought was occurring in each situation.

This video-based study examines the pragmatic non-verbal comprehension skills and corresponding neural-level findings in young Finnish autistic adults, and controls. Items from the Assessment Battery of Communication (ABaCo) were chosen to evaluate the comprehension of non-verbal communication. Inter-subject correlation (ISC) analysis of the functional magnetic resonance imaging data was used to reveal the synchrony of brain activation across participants during the viewing of pragmatically complex scenes of ABaCo videos.

Article Synopsis
  • This study focused on comparing autistic young adults to neurotypical young adults regarding social interactions and physiological responses.
  • Results showed significant differences in how each group interpreted social cues, paid attention to faces, and reacted physiologically (especially in terms of heart rate variability).
  • A notable finding was that autistic young adults who paid more attention to facial emotions tended to interpret social situations better, indicating that higher social attention helps with social understanding and emotional regulation.

Social and pragmatic difficulties in autism spectrum disorder (ASD) are widely recognized, although their underlying neural level processing is not well understood. The aim of this study was to examine the activity of the brain network components linked to social and pragmatic understanding in order to reveal whether complex socio-pragmatic events evoke differences in brain activity between the ASD and control groups. Nineteen young adults (mean age 23.

Previous studies have suggested that atypical deactivation of functional brain networks contributes to the complex cognitive and behavioral profile associated with autism spectrum disorder (ASD). However, these studies have not considered the temporal dynamics of deactivation mechanisms between the networks. In this study, we examined (a) mutual deactivation and (b) mutual activation-deactivation (i.

This study investigated whole-brain dynamic lag pattern variations between neurotypical (NT) individuals and individuals with autism spectrum disorder (ASD) by applying a novel technique called dynamic lag analysis (DLA). The use of 3D magnetic resonance encephalography data with repetition time = 100 msec enables highly accurate analysis of the spread of activity between brain networks. Sixteen resting-state networks (RSNs) with the highest spatial correlation between NT individuals (n = 20) and individuals with ASD (n = 20) were analyzed.

By utilizing the Pragma test this study investigated how sixteen five- to ten-year-old children with autism spectrum disorder (ASD) and sixteen typically developing (TD) children comprehended contextually challenging scenarios demanding 1) contextual inference with theory of mind (ToM), 2) contextual inference without ToM, 3) relevant use of language, 4) recognition of feelings, and 5) understanding false beliefs. The study also compared children's ability to explain their own correct answers. In addition, this study evaluated the sensitivity of three different methods for discriminating the children with ASD from the TD children: 1) the Pragma test, 2) the Social Interaction Deviance Composite (SIDC) of Children's Communication Checklist-2 (CCC-2), and 3) the Theory of Mind subtest of the Developmental Neuropsychological Assessment, Second edition (NEPSY-II).

The aim of the current study was to investigate subtle characteristics of social perception and interpretation in high-functioning individuals with autism spectrum disorders (ASDs), and to study the relation between watching and interpreting. As a novelty, we used an approach that combined moment-by-moment eye tracking and verbal assessment. Sixteen young adults with ASD and 16 neurotypical control participants watched a video depicting a complex communication situation while their eye movements were tracked.

Background: Previous studies investigating neuropsychological functioning of children with autism spectrum disorder (ASD) have only analysed certain abilities, such as executive functions or language. While comprehensive assessment of the neuropsychological profile of children with ASD has been the focus of recent research, most of the published evidence originates from single centres. Though studies on differences in neuropsychological features of children with ASD across countries are essential for identifying different phenotypes of ASD, such studies have not been conducted.

Background: Social perception skills, such as understanding the mind and emotions of others, affect children's communication abilities in real-life situations. In addition to autism spectrum disorder (ASD), there is increasing knowledge that children with specific language impairment (SLI) also demonstrate difficulties in their social perception abilities.

Aims: To compare the performance of children with SLI, ASD and typical development (TD) in social perception tasks measuring Theory of Mind (ToM) and emotion recognition.

This research explores, within the framework of Relevance Theory, how children's ability to answer questions and explain their answers develops between the ages of 3 and 9 years. Two hundred and ten normally developing Finnish-speaking children participated in this study. The children were asked questions requiring processing of inferential meanings and routines, and were asked to explain their correct answers to elicit understanding about their awareness of how they had derived the answers from the context.

Unlabelled: This study examined irrelevant/incorrect answers produced by children with Asperger syndrome or high-functioning autism (7-9-year-olds and 10-12-year-olds) and normally developing children (7-9-year-olds). The errors produced were divided into three types: in Type 1, the child answered the original question incorrectly, in Type 2, the child gave a correct answer, but when asked a follow-up question, he/she explained the answer incorrectly, and in Type 3, the child first gave a correct answer or explanation, but continued answering, which ultimately led to an irrelevant answer. Analyses of Type 1 and 2 errors indicated that all the children tried to utilize contextual information, albeit incorrectly.

Utilizing relevance theory, this study investigated the ability of children with Asperger syndrome (AS) and high-functioning autism (HFA) to use context when answering questions and when giving explanations for their correct answers. Three groups participated in this study: younger AS/HFA group (age 7-9, n=16), older AS/HFA group (age 10-12, n=23) and a normally functioning control group (age 7-9, n=23). The results indicated that the younger AS/HFA group did less well when answering contextually demanding questions compared to the control group, and the performance of the older AS/HFA group fell in between the younger AS/HFA group and the control group.
