    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

    Do gaze cues in complex scenes capture and direct the attention of high functioning adolescents with ASD? evidence from eye-tracking

    Visual fixation patterns whilst viewing complex photographic scenes containing one person were studied in 24 high-functioning adolescents with Autism Spectrum Disorders (ASD) and 24 matched typically developing adolescents. Over two different scene presentation durations both groups spent a large, strikingly similar proportion of their viewing time fixating the person’s face. However, time-course analyses revealed differences between groups in priorities of attention to the region of the face containing the eyes. It was also noted that although individuals with ASD were rapidly cued by the gaze direction of the person in the scene, this was not followed by an immediate increase in total fixation duration at the location of gaze, which was the case for typically developing individuals

    USING PRAISE TO INCREASE VISUAL ATTENDING IN AN ASYNCHRONOUS ONLINE LEARNING ENVIRONMENT: AN EYE TRACKING STUDY

    With the emergence of online courses in the mid-1990s, the number of students enrolled in online courses has been growing at an exponential rate (Schwirzke, Vashaw, & Watson, 2018). This trend brings with it new problems, such as familiarity with evidence-supported behavioral techniques that will maintain student engagement and improve likelihood of academic success in online learning environments. The purpose of the present study was to examine how the use of praise may affect visual engagement with video lectures with the assistance of commercially available eye tracking technology. A secondary objective of the study was to identify how praise affects performance on post-lecture knowledge assessments of information delivered through online videos. Results indicated that three out of four undergraduate participants were visually engaged with the video lecture more when provided praise than in the absence of praise, while the fourth participant showed ceiling effects. Results also indicated that praise did not have a significant effect on post-lecture knowledge assessment accuracy. These results indicate that praise may have utility in improving visual engagement in online learning environments and that inexpensive eye tracking technology may be useful for measuring visual engagement in these environments

    USING CONTINGENT PRAISE TO INCREASE VISUAL ENGAGEMENT IN AN ASYNCHRONOUS ONLINE LEARNING ENVIRONMENT: AN EYE TRACKING STUDY

    As more students move to online learning, this results in not only new barriers but new opportunities in academia. The purpose of this study was to examine how behavior-contingent praise affects visual engagement with an online video lecture when using WebGazer, a publicly available eye tracking software, with a user’s integrated webcam. A second aim of this study was to examine if using WebGazer with an integrated webcam was a valid alternative to hand scoring when collecting visual engagement data. Results of WebGazer measurement indicated a moderate effect size for three participants in the presence of contingent praise, and a large effect size was observed for one participant when provided contingent praise. Based on visual analysis and simple linear regression, level, shape of data paths, trend, and overall range of data were similar for three participants. One participant’s WebGazer and hand scoring data demonstrated a notable discrepancy in range, level, and shape for the Demand and Praise conditions. These results indicate that contingent praise may result in an increase in visual engagement in online learning environments and that using WebGazer and an integrated webcam may be a valid tool for measuring visual engagement in online learning environments. Discrepancies in WebGazer and hand scoring data are discussed

    Developmental pathways to autism: a review of prospective studies of infants at risk

    Autism Spectrum Disorders (ASDs) are neurodevelopmental disorders characterized by impairments in social interaction and communication, and the presence of restrictive and repetitive behaviors. Symptoms of ASD likely emerge from a complex interaction between pre-existing neurodevelopmental vulnerabilities and the child's environment, modified by compensatory skills and protective factors. Prospective studies of infants at high familial risk for ASD (who have an older sibling with a diagnosis) are beginning to characterize these developmental pathways to the emergence of clinical symptoms. Here, we review the range of behavioral and neurocognitive markers for later ASD that have been identified in high-risk infants in the first years of life. We discuss theoretical implications of emerging patterns, and identify key directions for future work, including potential resolutions to several methodological challenges for the field. Mapping how ASD unfolds from birth is critical to our understanding of the developmental mechanisms underlying this disorder. A more nuanced understanding of developmental pathways to ASD will help us not only to identify children who need early intervention, but also to improve the range of interventions available to them

    Training & prompting pre-service teachers’ noticing in a standardized classroom simulation – a mobile eye-tracking study

    Numerous events happening in classrooms require a teacher to select important and filter out irrelevant information. This crucial and challenging skill is referred to as noticing. For noticing classroom management events pre-service teachers have a smaller knowledge base and little teaching experience compared to expert teachers. Supporting pre-service teachers in developing their classroom management knowledge and noticing skill is, thus, of great importance for teacher education. Previous research finds positive effects of interventions on teachers’ noticing during video observation. To our knowledge, no studies depict noticing during teaching. We examined N = 46 pre-service teachers’ noticing with regard to classroom management during classroom teaching in a quasi-experimental between-subjects design. Pre-service teachers’ took part in a standardized classroom simulation after a classroom management training, with one group receiving prompting regarding evidence-based classroom management strategies before and during the classroom simulation and one group receiving only training. We also included a control group without classroom management training. To assess differences in pre-service teachers’ noticing, the classroom simulation elicited comparable conditions, including standardized classroom management events and student behavior. Mobile eye-tracking as well as retrospective video observations were used to explore teachers’ event-related and global noticing. Event-related noticing was assessed via count and accuracy of noticed classroom management events. Global noticing included objective parameters of teachers eye movements (visit/fixation counts and duration) onto the students in the standardized classroom simulation. The results show that training and prompting significantly affected pre-service teachers’ event-related noticing, with both experimental groups making fewer target and time errors compared to the control group. No significant differences were found with regard to global noticing. This includes fixation and visit count and duration on students. Correlational analysis showed a positive association between higher noticing accuracy and share of fixations on students. This study expands upon previous empirical research using mobile eye-tracking to obtain objective measures of teachers’ noticing. It sheds light on the relevance of knowledge for teachers’ noticing during teaching. It also takes a first step toward understanding how pre-service teachers’ noticing during classroom teaching can be promoted through fostering knowledge about classroom management through a training
