AbstractIn two studies, we used the Gottschaldt’s Hidden Figure Test (GHFT) for assessing figure disembedding ability in children aged 7–11. Study 1 demonstrated in a large sample of typically developing children that GHFT accuracy and time scores differed across age groups, without sex and socioeconomic differences. Thus, we provided normative data only taking into account children’s age. In Study 2, GHFT normative values were used to assess children with autism, who were also compared with a closely age-matched group of typical controls. Children with autism achieved time scores at or above the 50th centile and significantly differed from the controls for time score. The GHFT seems a valuable tool for defining the cognitive profile of children with autism.

ABSTRACTAlthough pragmatic deficits are well documented in autism, little is known about the extent to which grammatical knowledge in this disorder is deficient, or merely delayed when compared to that of typically developing children functioning at similar linguistic or cognitive levels. This study examines the knowledge of constraints on the interpretation of personal and reflexive pronouns, an aspect of grammar not previously investigated in autism, and known to be subject to differential developmental schedules in unimpaired development. Fourteen children with autism (chronological age = 6–17 years,M= 11) showed some difficulties comprehending personal pronouns, no different from those observed in two groups of younger controls matched on nonverbal IQ or receptive grammar, but in line with the reported pragmatic deficits and general language delay in this population. However, their interpretation of reflexives was significantly worse than that of the control children. This pattern is not evidenced at any stage of typical development, revealing an impaired grammatical knowledge in our sample of children with autism, and is argued not to be due to a general language delay or cognitive deficits.

Difficulties with face recognition increase from adolescence to adulthood in autism, reflecting a lack of typical late development. We examined whether this reflects differences in the development of patterns of fixation to eyes and mouths during face recognition. Children, adolescents, and adults (aged 7–30) with and without autism completed the Cambridge Face Memory Test while gaze was recorded. Average duration and number of fixations were calculated for eyes and mouth regions of interest, defined individually for each face image in the task. All groups and age groups made more and longer fixations to eyes than mouths. However, during face memorization, typically developing children and adults, but not adolescents, made more fixations to eyes than did their peers with autism. During face recognition, typically developing children and adults made shorter fixations on mouths than did their peers with autism; this pattern was reversed in adolescence, with adolescents with autism making more fixations to mouths than typically developing adolescents. Results suggest that group differences in patterns of fixations to faces change with age. Furthermore, different relationships between patterns of fixations and face recognition performance in typical development and autism suggest that these differences contribute, at least in part, to difficulties in autism.

AbstractFailure to develop prospective motor control has been proposed to be a core phenotypic marker of autism spectrum disorders (ASD). However, whether genuine differences in prospective motor control permit discriminating between ASD and non-ASD profiles over and above individual differences in motor output remains unclear. Here, we combined high precision measures of hand movement kinematics and rigorous machine learning analyses to determine the true power of prospective movement data to differentiate children with autism and typically developing children. Our results show that while movement is unique to each individual, variations in the kinematic patterning of sequential grasping movements genuinely differentiate children with autism from typically developing children. These findings provide quantitative evidence for a prospective motor control impairment in autism and indicate the potential to draw inferences about autism on the basis of movement kinematics.

The objective of this study was to compare experiential grammar in the narrative discourse of thirty typically developing Thai children and thirty Thai children with autism in elementary grades 1 to 3. Data was compiled by asking subjects to tell a narrative discourse from a wordless storybook "A Boy, a Dog, and a Frog” (Mayer 1967). Data was analyzed based on the Systemic Functional Linguistics approach and focused on experiential mode of meaning concerned with the system of Transitivity. The results revealed that children with autism used fewer clause complexes and clause simplexes than typically developing children. For the system of Transitivity, it was found that children with autism used less modified nominal groups as the Participant especially in grade 2 and 3 and they used a smaller number and less variety of process types; used a lower percentage of mental, behavioral and verbal processes; and used a lower percentage of serial verb constructions. Children with autism, especially those in grades 2 and 3, used a smaller variety of circumstance types; and used a lower percentage of clauses with complex circumstances.

Eye gaze direction and expression intensity effects on emotion recognition in children with autism disorder and typically developing children were investigated. Children with autism disorder and typically developing children identified happy and angry expressions equally well. Children with autism disorder, however, were less accurate in identifying fear expressions across intensities and eye gaze directions. Children with autism disorder rated expressions with direct eyes, and 50% expressions, as more intense than typically developing children. A trend was also found for sad expressions, as children with autism disorder were less accurate in recognizing sadness at 100% intensity with direct eyes than typically developing children. Although the present research showed that children with autism disorder are sensitive to eye gaze direction, impairments in the recognition of fear, and possibly sadness, exist. Furthermore, children with autism disorder and typically developing children perceive the intensity of emotional expressions differently.

Background: Children with cerebral palsy (CP) have difficulty in managing postural control during functional reaching tasks, although children with different postural control ability are able to come up with different motor solutions to cope with different task demands. This study examined the effect of task constraint on postural control performance in children with cerebral palsy and typical development (TD) in terms of different postural control abilities. Methods: A cross-sectional research design was used. Twelve children with spastic diplegic cerebral palsy (mean age: 107.8 months) and 16 typically developing children (mean age: 110.9 months) participated in this study. Individually, all subjects were seated in a height-adjusted chair and were requested to reach for target(s) located at three different directions (medial, anterior, and lateral). A six-camera Qualisys Motion Capture System was used to capture motion data. Kinematic data in terms of body alignment and angular changes were analyzed. Results: Children with cerebral palsy demonstrated different postural control strategies to complete different reaching tasks compared to typically developing children by preparing postural alignment in advance, coordinating different body orientation movements during reaching after showing difficulty in managing reach medially. Conclusions: Children with cerebral palsy perceive their insufficient ability and prepare their alignment in advance to adapt to the task demanded and decrease the postural challenges of the task. Even though children with cerebral palsy self-generate different motor solutions to reach without falling, these alternative strategies might not be the most efficient adaptation.

Abstract Background: Previous research studies have demonstrated abnormalities in the metabolism of mothers of young children with autism.Method: Metabolic analysis was performed on blood samples from 30 mothers of young children with Autism Spectrum Disorder (ASD-M) and from 29 mothers of young typically-developing children (TD-M). Targeted metabolic analysis focusing on the folate one-carbon metabolism (FOCM) and the transsulfuration pathway (TS) as well as broad metabolic analysis were performed. Statistical analysis of the data involved both univariate and multivariate statistical methods.Results: Univariate analysis revealed significant differences in 5 metabolites from the folate one-carbon metabolism and the transsulfuration pathway and differences in an additional 48 metabolites identified by broad metabolic analysis, including lower levels of many carnitine-conjugated molecules. Multivariate analysis with leave-one-out cross-validation allowed classification of samples as belonging to one of the two groups of mothers with 93% sensitivity and 97% specificity with five metabolites. Furthermore, each of these five metabolites correlated with 8-15 other metabolites indicating that there are five clusters of correlated metabolites. In fact, all but 5 of the 50 metabolites with the highest area under the receiver operating characteristic curve were associated with the five identified groups. Many of the abnormalities appear linked to low levels of folate, vitamin B12, and carnitine-conjugated molecules.Conclusions: Mothers of children with ASD have many significantly different metabolite levels compared to mothers of typically developing children at 2-5 years after birth.
