Clinical Heterogeneity Among Preschoolers Recruited as Infants Due to Elevated Likelihood of Autism
Autism spectrum disorder (ASD), attention‐deficit/hyperactivity disorder (ADHD), and developmental language disorder (DLD) are neurodevelopmental conditions (NDCs) that share etiological factors and frequently co‐occur. Despite this, they have rarely been studied together—particularly in relation to functional outcomes. In this study, we investigate the association between the developmental pattern of sustained visual attention in infancy and num…
Automated Infant Eye Tracking
Automated eye tracking has emerged as a powerful method in psychology, and has special benefits when studying infant populations. The field has developed much during the last decades, and while there are numerous reviews on methodological aspects and specific research topics, a general overview of the state and trends of the field has been lacking. That lack leaves the field unguided on several important aspects such as WEIRDness, statistical pow…
Larger pupil dilation to nonsocial sounds in infants with subsequent autism diagnosis
BACKGROUND: Studies of infants with an elevated likelihood of autism spectrum disorder can identify basic developmental processes that are associated with subsequently emerging clinical symptoms. Atypical responsiveness to sounds in infancy is such a potential early marker of autism. Here, we used pupillometry to quantify reactivity to social and nonsocial sounds in infants with a subsequent diagnosis. Previous research suggest that pupil dilatio…
Pupil size and pupillary light reflex in early infancy
BACKGROUND: Measures based on pupillometry, such as the pupillary light reflex (PLR) and baseline pupil size, reflect physiological responses linked to specific neural circuits that have been implicated as atypical in some psychiatric and neurodevelopmental conditions. METHODS: We investigated the contribution of genetic and environmental factors to the baseline pupil size and the PLR in 510 infant twins assessed at 5 months of age (281 monozygot…
A Pre-registered sticky mittens study
Several studies have previously investigated the effects of sticky mittens training on reaching and grasping development. However, recent critique casted doubts on the robustness of the motor effect of this training. The current study presents a pre-registered report that aimed to generalize these effects to Swedish infants. Three-month-old infants N = 96, 51 females, mostly White middle class in Uppsala, received daily, parent-led sticky mittens…
Development of the pupillary light reflex from 9 to 24 months
Background Although autism spectrum disorder (ASD) is heritable, the mechanisms through which genes contribute to symptom emergence remain unclear. Investigating candidate intermediate phenotypes such as the pupillary light reflex (PLR) prospectively from early in development could bridge genotype and behavioural phenotype. Methods Using eye tracking, we longitudinally measured the PLR at 9, 14 and 24 months in a sample of infants ( N = 264) enri…
Infants prospectively control reaching based on the difficulty of future actions
Prospective motor control, a key element of action planning, is the ability to adjust one's actions with respect to task demands and action goals in an anticipatory manner. The current study investigates whether 14-month-olds can prospectively control their reaching actions based on the difficulty of the subsequent action. We used a reach-to-place task, with difficulty of the placing action varied by goal size and goal distance. To target prospec…
Visual Attention to Dynamic Spatial Relations in Infants and Adults
Previous research has found that kinematic features of interactions, such as spatial proximity, capture adult visual attention. The current research uses online measures of gaze behavior to determine attentional capture to objects with reduced interobject spacing in adults as well as infants at 5 and 12 months. The three age groups observed three identical geometrical shapes that moved randomly. Relative distance between the objects was mapped an…
