Abstract: To examine visual attention to faces within social scenes in children with neurofibromatosis type 1 (NF1) and typically developing peers. Using eye-tracking technology we investigated the time taken to fixate on a face and the percentage of time spent attending to faces relative to the rest of the screen within social scenes in 24 children with NF1 (17 females, seven males mean age 10y 4mo [SD 1y 9mo]). Results were compared with those of 24 age-matched typically developing controls (11 females, 13 males mean age 10y 3mo [SD 2y]). There was no significant between-group differences in time taken to initially fixate on a face (p=0.617) however, children with NF1 spent less time attending to faces within scenes than controls (p=0.048). Decreased attention to faces was associated with elevated autism traits in children with NF1. Children with NF1 spend less time attending to faces than typically developing children when presented in social scenes. Our findings contribute to a growing body of literature suggesting that abnormal face processing is a key aspect of the social-cognitive phenotype of NF1 and appears to be related to autism spectrum disorder traits. Clinicians should consider the impact of reduced attention to faces when designing and implementing treatment programmes for social dysfunction in this population. Children with neurofibromatosis type 1 (NF1) demonstrated atypical gaze behaviour when attending to faces. NF1 gaze behaviour was characterized by normal initial fixation on faces but shorter face dwell time. Decreased attention to faces was associated with elevated autism traits in the s le with NF1.

Abstract: This study aimed to investigate face scan paths and face perception abilities in children with Neurofibromatosis Type 1 (NF1) and how these might relate to emotion recognition abilities in this population. The authors investigated facial emotion recognition, face scan paths, and face perception in 29 children with NF1 compared to 29 chronological age-matched typically developing controls. Correlations between facial emotion recognition, face scan paths, and face perception in children with NF1 were examined. Children with NF1 displayed significantly poorer recognition of fearful expressions compared to controls, as well as a nonsignificant trend toward poorer recognition of anger. Although there was no significant difference between groups in time spent viewing in idual core facial features (eyes, nose, mouth, and nonfeature regions), children with NF1 spent significantly less time than controls viewing the face as a whole. Children with NF1 also displayed significantly poorer face perception abilities than typically developing controls. Facial emotion recognition deficits were not significantly associated with aberrant face scan paths or face perception abilities in the NF1 group. These results suggest that impairments in the perception, identification, and interpretation of information from faces are important aspects of the social-cognitive phenotype of NF1.

Abstract: A significant proportion of health‐ and disability‐sector consumers in Australia speak a language other than English (LOTE) at home. Barriers to service access in culturally and linguistically erse (CALD) populations are acknowledged however, there is limited data to guide service delivery among care providers. The aims of the present study were to investigate the linguistic ersity of preschool‐aged children and families presenting for diagnostic assessment of developmental delay and disability at the Disability Specialist Unit, a multidisciplinary assessment service, and assess whether CALD status was associated with poorer service engagement. Specifically, it was hypothesized that CALD status would be associated with decreased likelihood of receiving intervention (particularly multidisciplinary intervention) and attending center‐based care, and an increased likelihood of requiring referral to access available government funding. A retrospective record audit was undertaken of 88 clients seen by the Disability Specialist Unit over a 12‐month period to collect information about CALD status (whether a LOTE was spoken at home) and a range of clinically relevant variables including clinical diagnosis/es, age at assessment, involvement with therapies, attendance at center‐based child care, and whether a referral to access government funding was required. Differences between CALD and non‐CALD groups were explored statistically via odds ratios and independent s les t test. Children from CALD backgrounds were significantly less likely than non‐CALD children to be engaged in multidisciplinary therapy at the time of assessment and significantly more likely to require support to access funding than children from non‐CALD families. Furthermore, children from CALD backgrounds were significantly more likely to receive a diagnosis of autism spectrum disorder and global developmental delay or ID. These findings suggest that children from CALD backgrounds are disadvantaged compared to non‐CALD children with respect to service access at the point of tertiary diagnostic evaluation of a developmental disability. Implications for service delivery are discussed.
