Gaze following, gaze reading, and word learning in children at-risk for autism

We investigated gaze following abilities as a prerequisite for word learning, in a population expected to manifest a wide range of individual variability – children with a family history of autism. Three-year-olds with or without a family history of autism took part in a word-learning task that required following gaze to find the correct referent of a novel word. Using an eye-tracker to monitor children’s gaze behavior we show that the ability to follow an adult’s gaze was necessary but not sufficient for successful word learning. Those children that had poor social and communicative skills could follow gaze to the correct object, but did not then learn the word associated with that object. These findings shed light on the conditions that lead to successful or less successful word learning in typical and atypical populations

Perspectives from parents of autistic children on participating in early intervention and associated research

Early support should help autistic children lead flourishing lives. We sought to understand parents’ experiences of their children’s involvement in early intervention and associated research, through focus groups with 23 parents (of 22 children) enrolled in a university-affiliated service. Reflexive thematic analysis revealed four themes. Parents conveyed a strong sense of gratitude (Theme 1) arising from their perceptions of the importance of early intervention and feelings of having ‘hit the jackpot’ to secure access to the service from which they perceived their children ‘gained so much’. They valued the service and staff expertise which made them feel secure (Theme 2). University affiliation and the associated research also contributed to parents’ sense of safety, from perceived ‘accountability’ and ‘integrity’. Parents conveyed deep commitment to the service (Theme 3) but shared often-negative experiences as their child’s enrolment came to an end (Theme 4) and they expressed feelings of abandonment and disempowerment, being confronted with the reality of needing to secure next-stage support for their children and of perceived critical need for ‘conversion of research into practice’. These parents’ accounts offer insights into the benefits and ongoing challenges of achieving truly effective supports for autistic preschoolers and their families. Lay abstract: Support for autistic children early in life should help them to lead flourishing lives. However, many of the early intervention programmes for young autistic children are time-consuming and costly for families. These programmes are also often conducted in settings that are not closely matched to real life. We spoke to 23 parents (of 22 autistic children) to understand their experiences of their children’s involvement in early intervention. Parents told us they were grateful for the opportunity, that they had ‘hit the jackpot’, and their children had ‘gained so much’ from the programme. They seemed to value the service because it made them feel safe and secure during an uncertain time in their children’s lives. Parents told us they trusted staff, felt that they weren’t ‘doing it alone’, and this ‘took that pressure off’ and helped them feel empowered. They also spoke of feelings of safety from being linked to the university research programme which offered ‘accountability’ and ‘integrity’. Parents’ comments showed a strong commitment to the early intervention model and staff – but also common feelings of abandonment and disempowerment as their child’s time with the programme came to an end and they went ‘back to the real world’ and needed to find new supports for their children. These parents’ insights should help to inform the design and delivery of community supports for preschool-aged autistic children and their families, which match the reality of their lived experiences

The Modified-Classroom Observation Schedule to Measure Intentional Communication (M-COSMIC): Evaluation of reliability and validity

The Modified – Classroom Observation Schedule to Measure Intentional Communication (M-COSMIC) was developed as an ecologically valid measure of social-communication behaviour, delineating forms, functions, and intended partners of children’s spontaneous communication acts. Forty one children with autism spectrum disorder (ASD) aged 48 to 73 months were filmed within small-group settings at school. Communication behaviours during a five-minute teacher-led activity and a 10-minute free play session were coded from video-tape. Inter-rater reliability was high. Many M-COSMIC codes were significantly associated as predicted with Social and Communication domain scores on the Autism Diagnostic Observation Schedule (ADOS) and with scores on standardised language assessments. Agreement was more variable, however, at the level of individual M-COSMIC codes and ADOS items. Higher rates of responding, compliance behaviours and following pointing gestures and gaze occurred during the more structured teacher-led activity, compared to the free play. Results demonstrate preliminary construct validity of the M-COSMIC, showing its potential to describe and evaluate spontaneous social-communication skills in young children with ASD for research and applied purposes

Development of adaptive communication skills in infants of blind parents.

A fundamental question about the development of communication behavior in early life is how infants acquire adaptive communication behavior that is well-suited to their individual social environment, and how the experience of parent-child communication affects this development. The current study investigated how infants develop communication skills when their parents are visually impaired and cannot see their infants' eye gaze. We analyzed 6-min video recordings of naturalistic interaction between 14 sighted infants of blind parents (SIBP) with (a) their blind parent, and (b) a sighted experimenter. Data coded from these interactions were compared with those from 28 age-matched sighted infants of sighted parents (controls). Each infant completed two visits, at 6-10 months and 12-16 months of age. Within each interaction sample, we coded the function (initiation or response) and form (face gaze, vocalization, or action) of each infant communication behavior. When interacting with their parents, SIBP made relatively more communicative responses than initiations, and used more face gaze and fewer actions to communicate, than did controls. When interacting with a sighted experimenter, by contrast, SIBP made slightly (but significantly) more communicative initiations than controls, but otherwise used similar forms of communication. The differential communication behavior by infants of blind versus sighted parents was already apparent by 6-10 months of age, and was specific to communication with the parent. These results highlight the flexibility in the early development of human communication behavior, which enables infants to optimize their communicative bids and methods to their unique social environment.

Face engagement during infancy predicts later face recognition ability in younger siblings of children with autism

Face recognition difficulties are frequently documented in children with autism spectrum disorders (ASD). It has been hypothesized that these difficulties result from a reduced interest in faces early in life, leading to decreased cortical specialization and atypical development of the neural circuitry for face processing. However, a recent study by our lab demonstrated that infants at increased familial risk for ASD, irrespective of their diagnostic status at 3 years, exhibit a clear orienting response to faces. The present study was conducted as a follow-up on the same cohort to investigate how measures of early engagement with faces relate to face-processing abilities later in life. We also investigated whether face recognition difficulties are specifically related to an ASD diagnosis, or whether they are present at a higher rate in all those at familial risk. At 3 years we found a reduced ability to recognize unfamiliar faces in the high-risk group that was not specific to those children who received an ASD diagnosis, consistent with face recognition difficulties being an endophenotype of the disorder. Furthermore, we found that longer looking at faces at 7 months was associated with poorer performance on the face recognition task at 3 years in the high- risk group. These findings suggest that longer looking at faces in infants at risk for ASD might reflect early face-processing difficulties and predicts difficulties with recognizing faces later in life

Infant Neural Sensitivity to Dynamic Eye Gaze relates to quality of parent–infant interaction at 7-months in infants at risk for Autism

Links between brain function measures and quality of parent–child interactions within the early developmental period have been investigated in typical and atypical development. We examined such links in a group of 104 infants with and without a family history for autism in the first year of life. Our findings suggest robust associations between event related potential responses to eye gaze and observed parent–infant interaction measures. In both groups, infants with more positive affect exhibit stronger differentiation to gaze stimuli. This association was observed with the earlier P100 waveform component in the control group but with the later P400 component in infants at-risk. These exploratory findings are critical in paving the way for a better understanding of how infant laboratory measures may relate to overt behavior and how both can be combined in the context of predicting risk or clinical diagnosis in toddlerhood

Agent familiarity and emotional context influence the everyday empathic responding of young children with autism

Whereas research addressing empathy in ASD tends to employ pencil-and-paper and lab-based behavioural methods, the current study is novel in eliciting parent-report data regarding everyday empathy, sampling various emotional situations regularly encountered by children. Parents of typically-developing children and children diagnosed with ASD and DS completed the newly-developed Day-to-Day Child Empathy Questionnaire. Analysis of descriptions of their children’s responses to the various empathy-inducing situations supports the notion of an empathy deficit in ASD, confirming previous laboratory-based findings. However, important moderation effects were also demonstrated, for both control and clinical groups. In particular, parents reported children in all groups to be more likely to respond empathically to a familiar agent. The nature of children’s responses also according to the specific emotional context

Infant regulatory function acts as a protective factor for later traits of autism spectrum disorder and attention deficit/hyperactivity disorder but not callous unemotional traits

Abstract: Background: Reduced executive functions (EF) are commonly associated with developmental conditions (e.g., autism spectrum disorder, ASD; attention deficit/hyperactivity disorder, ADHD), although EF seems to be typical in children with callous unemotional (CU) traits. Regulatory function (RF) is a proposed infant precursor that maps on onto factors driving later EF. Here, we first test whether RF is specifically and negatively associated with ASD and ADHD traits, but not CU traits. Second, we test whether RF can act as a protective factor, by moderating the association between infant markers and subsequent ASD and ADHD traits. Methods: Participants were 79 infants at high (N = 42) and low (N = 37) familial risk for ASD. Data come from the 14-month infant visit (Autism Observational Scale for Infants; AOSI; activity level and RF from the Infant Behavior Questionnaire; IBQ) and the 7-year visit (ASD traits: Social Responsiveness Scale, SRS; ADHD traits: Conners 3, CU traits: Inventory of Callous Unemotional Traits). Results: Infant RF was negatively associated with later traits of ASD (B = − 0.5, p = 0.01) and ADHD inattention (B = − 0.24, p = 0.02) but not hyperactivity (B = − 0.25, p = 0.10) or CU traits (B = 0.02, p = 0.86). RF moderated the association between infant AOSI score and ASD traits, with a significant effect in those with low RF (B = 0.10, p = 0.006), not high RF (B = 0.01, p = 0.78). Similarly, for ADHD, infant activity level was associated with later ADHD inattention in those with low (B = 0.17, p = 0.04) but not high RF (B = 0.07, p = 0.48). For ADHD hyperactivity symptoms, activity level was predictive at both high and low levels of RF. Conclusions: Strong RF may allow children to compensate for other atypicalities, thus attenuating the association between infant markers and later disorder traits. Whilst infant RF was associated with both ASD and ADHD inattention traits, there was no association with ADHD hyperactivity or CU traits. This suggests that any protective effect may not be universal and emphasises the need for a better understanding of the underlying moderating mechanisms

Early social experience affects the development of eye gaze processing

Eye gaze is a key channel of non-verbal communication in humans [1-3]. Eye contact with others is present from birth [4], and eye gaze processing is crucial for social learning and adult-infant communication [5-7]. However, little is known about the effect of selectively different experience of eye contact and gaze communication on early social and communicative development. To directly address this question, 14 sighted infants of blind parents (SIBP) were assessed longitudinally at 6-10 and 12-16 months. Face scanning [8] and gaze following [7, 9] were assessed using eye tracking. In addition, naturalistic observations were made when the infants were interacting with their blind parent and with an unfamiliar sighted adult. Established measures of emergent autistic-like behaviours [10] and standardized tests of cognitive, motor and linguistic development [11] were also collected. These data were then compared with those obtained from a group of infants of sighted parents. Despite showing typical social skills development overall, infants of blind parents allocated less attention to adult eye movements and gaze direction, an effect which increased between 6-10 and 12-16 months of age. The results suggest that infants adjust their use of adult's eye gaze depending on gaze communication experience from early in life. The results highlight that human functional brain development shows selective experience-dependent plasticity adaptive to the individual's specific social environment
