Abstract
INTRODUCTION Developmental disabilities and neuromotor delay adversely affect long-term neuromuscular function and quality of life. Current evidence suggests that early therapeutic intervention reduces the severity of motor delay by harnessing neuroplastic potential during infancy. To date, most early therapeutic intervention trials are of limited duration and do not begin soon after birth and thus do not take full advantage of early neuroplasticity. The Corbett Ryan-Northwestern-Shirley Ryan AbilityLab-Lurie Children's Infant Early Detection, Intervention and Prevention Project (Project Corbett Ryan) is a multi-site longitudinal randomized controlled trial to evaluate the efficacy of an evidence-based physical therapy intervention initiated in the neonatal intensive care unit (NICU) and continuing to 12 months of age (corrected when applicable). The study integrates five key principles: active learning, environmental enrichment, caregiver engagement, a strengths-based approach, and high dosage (ClinicalTrials.gov identifier NCT05568264). METHODS We will recruit 192 infants at risk for neuromotor delay who were admitted to the NICU. Infants will be randomized to either a standard-of-care group or an intervention group; infants in both groups will have access to standard-of-care services. The intervention is initiated in the NICU and continues in the infant's home until 12 months of age. Participants will receive twice-weekly physical therapy sessions and caregiver-guided daily activities, assigned by the therapist, targeting collaboratively identified goals. We will use various standardized clinical assessments (General Movement Assessment; Bayley Scales of Infant and Toddler Development, 4th Edition (Bayley-4); Test of Infant Motor Performance; Pediatric Quality of Life Inventory Family Impact Module; Alberta Infant Motor Scale; Neurological, Sensory, Motor, Developmental Assessment; Hammersmith Infant Neurological Examination) as well as novel technology-based tools (wearable sensors, video-based pose estimation) to evaluate neuromotor status and development throughout the course of the study. The primary outcome is the Bayley-4 motor score at 12 months; we will compare scores in infants receiving the intervention vs. standard-of-care therapy.

Abstract
Infants demonstrate rapid development across the first years of life, which underlies increased human interactions that promote social-emotional development. In particular, gaze, affect, and object exploration are early indicators of engagement and show rapid changes in the first year of life. However, current understanding on developmental trajectories during infancy often comes from majority white, non-Hispanic/Latino samples. This longitudinal study explored the development of infant gaze, affect, and object exploration across 2-18 months of age in a sample of primarily Latino infants drawn from a pediatric community clinic. Videos of mother-infant play when infants were 2, 6, 9, 12 and 18 months were coded for durations of three types of behaviors: gaze, affect, and object exploration. Additionally, mother-infant play videos when the infant was 24 months of age were coded for joint engagement. Descriptive statistics for the three behavior types were obtained at each timepoint, and repeated measures analysis of covariance investigated the development of behaviors from timepoint to timepoint. Latent growth curve analyses were conducted to analyze developmental trajectories of capacities across 2-18 months, as well as development in relation to joint engagement at 24 months. Results indicate an important development period from 2 to 6 months of infants' life, unique developmental patterns of specific behaviors, and heterogeneity in gaze development in the sample and across ages. Overall, this study provides an important description of development within mother-infant play in a primarily Latino sample.

Abstract
AIM To systematically review evidence of the effectiveness of sticky mittens training to improve reaching skills and manual exploration of full-term and at-risk infants and optimal training dosage. METHODS The Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guided this systematic review. The electronic search was performed from September 2017 to August 2021 on PubMed, Scopus, Science Direct, and Cochrane databases. Eligibility criteria followed PICO terms: clinical trials investigating the effects of sticky mittens training on reaching skills and manual exploration of full-term and at-risk infants. PEDro scale and GRADE assessed methodological quality and quality of evidence, respectively. RESULTS Eight studies (313 children) were included. Five studies found statistically significant differences between experimental and control groups (62.6%). One study presented high methodological quality. Evidence synthesis showed very low and low evidence of the beneficial effects of sticky mittens training in full-term and at-risk infants, respectively. CONCLUSIONS Findings suggest that sticky mittens training facilitates reaching skills and manual exploration. However, results should interpretation with caution because studies targeted full-term infants. Future research should focus on infants at risk or with motor impairments since sticky mittens training seems to show positive effects and is easy to apply.

Abstract
PURPOSE The purpose of this systematic review was to identify controlled trials evaluating the efficacy of contingency paradigm-based interventions to improve feeding, motor, or cognitive outcomes during the first year of life. SUMMARY OF KEY POINTS Seventeen studies, including 10 randomized controlled trials, incorporating contingency paradigm-based interventions were identified. Three of 3 trials reported improvements in nutritive sucking using pacifier-activated lullaby in preterm infants before term age. Seven of 12 trials reported improvements in reaching, manual exploration, and kicking behaviors in term and preterm infants; and 6 of 10 trials reported gains in early cognition using sticky mittens and contingent toys. CONCLUSION AND RECOMMENDATIONS FOR CLINICAL PRACTICE Contingency paradigm-based interventions can improve feeding outcomes in the neonatal intensive care unit in very preterm infants, and increase reaching, and perceptual-cognitive behaviors in term infants. Future research is needed to establish contingency paradigms as an effective early intervention strategy. WHAT THIS ADDS TO THE EVIDENCE This review synthesizes a body of literature on contingency paradigm-based interventions and highlights its potential paradigm-based interventions to improve developmental outcomes in infants.

Abstract
Recent neuroimaging studies allowed us to explore abnormal brain structures and interhemispheric connectivity in children with cerebral palsy (CP). Behavioral researchers have long reported that children with CP exhibit suboptimal performance in different cognitive domains (e.g., receptive and expressive language skills, reading, mental imagery, spatial processing, subitizing, math, and executive functions). However, there has been very limited cross-domain research involving these two areas of scientific inquiry. To stimulate such research, this perspective paper proposes some possible neurological mechanisms involved in the cognitive delays and impairments in children with CP. Additionally, the paper examines the ways motor and sensorimotor experience during the development of these neural substrates could enable more optimal development for children with CP. Understanding these developmental mechanisms could guide more effective interventions to promote the development of both sensorimotor and cognitive skills in children with CP.

Infants exploring objects: A cascades perspective. ADVANCES IN CHILD DEVELOPMENT AND BEHAVIOR 2022; 64:39-68.

Abstract
Infants spend much of their time exploring objects (Herzberg et al., 2021), and object exploration is linked to learning and development in various domains (e.g., social, cognitive, motor). But how does exploration develop in the first place, and how, exactly, does exploration promote learning? One way to approach these process-oriented questions is with a developmental cascades perspective, which holds that new skills emerge from earlier-developing ones and that various interactions with people and objects accumulate over time to influence multiple domains of development (Masten & Cicchetti, 2010). In this chapter, we describe object exploration from a developmental cascades perspective. In Section 2, we describe typical and atypical trajectories of exploration behaviors, noting how these behaviors emerge from earlier-developing cognitive and motor skills. In Section 3, we discuss how object exploration opens the door for new types of learning opportunities. In Section 4, we discuss early experiences that may shape the development of object exploration. Altogether, we aim to convey that new developments in exploration skills are extensions of earlier-developing skills, and that seemingly insignificant exploratory behaviors (e.g., shaking a rattle) may result in numerous and varied consequences for the developing infant.

Abstract
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 or observational training for 2 weeks or no training in 2019. Reaching and grasping abilities were assessed before and after training, using motion tracking and a 4-step reaching task. Sticky mittens training did not facilitate successful reaching. These results indicate that beneficial motor effects of sticky mittens training did not generalize to this sample.

Abstract
Visual attention develops rapidly and significantly during the first postnatal years. At birth, infants have poor visual acuity, poor head and neck control, and as a result have little autonomy over where and how long they look. Across the first year, the neural systems that support alerting, orienting, and endogenous attention develop, allowing infants to more effectively focus their attention on information in the environment important for processing. However, visual attention is a system that develops in the context of the whole child, and fully understanding this development requires understanding how attentional systems interact and how these systems interact with other systems across wide domains. By adopting a cascades framework we can better position the development of visual attention in the context of the whole developing child. Specifically, development builds, with previous achievements setting the stage for current development, and current development having cascading consequences on future development. In addition, development reflects changes in multiple domains, and those domains influence each other across development. Finally, development reflects and produces changes in the input that the visual system receives; understanding the changing input is key to fully understand the development of visual attention. The development of visual attention is described in this context.

Abstract
Numerous conditions and circumstances place infants at risk for poor neuromotor health, yet many are unable to receive treatment until a definitive diagnosis is made, sometimes several years later. In this integrative perspective, we describe an extensive team science effort to develop a transdiagnostic approach to neuromotor health interventions designed to leverage the heightened neuroplasticity of the first year of life. We undertook the following processes: (1) conducted a review of the literature to extract common principles and strategies underlying effective neuromotor health interventions; (2) hosted a series of expert scientific exchange panels to discuss common principles, as well as practical considerations and/or lessons learned from application in the field; and (3) gathered feedback and input from diverse stakeholders including infant caregivers and healthcare providers. The resultant framework was a pragmatic, evidence-based, transdiagnostic approach to optimize neuromotor health for high-risk infants based on four principles: (a) active learning, (b) environmental enrichment, (c) caregiver engagement, and (d) strength-based approaches. In this perspective paper, we delineate these principles and their potential applications. Innovations include: engagement of multiple caregivers as critical drivers of the intervention; promoting neuromotor health in the vulnerability phase, rather than waiting to treat neuromotor disease; integrating best practices from adjacent fields; and employing a strengths-based approach. This framework holds promise for implementation as it is scalable, pragmatic, and holistically addresses both the needs of the infant and their family.

Abstract
Almost two decades ago, the sticky mittens paradigm was demonstrated as a way to train reaching and grasping behaviors in pre‐reaching infants, and consequently improve visual attentional abilities. In that first study, Needham and colleagues fitted 3‐month‐old infants with Velcro loop‐covered mittens and allowed them to interact with Velcro hook‐covered toys over the course of 2 weeks. In this review, we scrutinize the 17 studies that have followed those first sticky mittens results in regards to the motor, social perception, and visual attentional domains. Furthermore, we discuss the proposed mechanisms of the sticky mittens training. Current evidence strongly suggests that sticky mittens training facilitates social perception, which is consistent with prior correlational work showing links between action production and action perception. However, studies targeting motor and visual attentional abilities have too diverse results to warrant firm conclusions. We conclude that future research should focus on uncovering if there is a connection between sticky mittens training and motor behavior.

Abstract
According to the influential "Two Visual Pathways" hypothesis, the cortical visual system is segregated into two pathways, with the ventral, occipitotemporal pathway subserving object perception, and the dorsal, occipitoparietal pathway subserving the visuomotor control of action. However, growing evidence suggests that the dorsal pathway also plays a functional role in object perception. In the current article, we present evidence that the dorsal pathway contributes uniquely to the perception of a range of visuospatial attributes that are not redundant with representations in ventral cortex. We describe how dorsal cortex is recruited automatically during perception, even when no explicit visuomotor response is required. Importantly, we propose that dorsal cortex may selectively process visual attributes that can inform the perception of potential actions on objects and environments, and we consider plausible developmental and cognitive mechanisms that might give rise to these representations. As such, we consider whether naturalistic stimuli, such as real-world solid objects, might engage dorsal cortex more so than simplified or artificial stimuli such as images that do not afford action, and how the use of suboptimal stimuli might limit our understanding of the functional contribution of dorsal cortex to visual perception.

Abstract
Infants from low-income households typically spend less time exploring objects and use less mature strategies when they do explore compared to their higher-income peers (e.g., Clearfield et al., 2014). The current study tested a novel intervention designed to boost early object exploration in infants from low-income households. The intervention, called Play for Success, was administered through the Early Head Start home visiting program, and asked all infants to explore a toy with a caregiver for 10 min a day every day for two weeks. Forty-two 6- to 10-month-old infants were randomly assigned to one of three intervention groups: Social (unstructured direction), Teach Two (simple structured direction), or Teach Many (complex structured direction). Infants' exploratory behaviors were tested three times: before the intervention, immediately following, and again four weeks later. The results demonstrated that only infants in Teach 2 maintained their level of exploration at both the post-test and 4 weeks later while infants in the other groups showed significant decreases in exploration over time. These results suggest that Play for Success is a promising new intervention, but only in the condition that included repeated simple structured direction.

Abstract
OBJECTIVE To examine whether a brief reaching training with sticky mittens was effective to improve reaching behavior in newly reaching preterm infants. METHODS In this randomized controlled trial, twenty four 5-month-old (±16-week-old corrected age) preterm infants were randomly allocated into experimental or control groups. Infants were assessed three times in a single session: pretraining (immediately before training), posttraining (immediately after training), and retention (4 min after the posttraining). During training, infants in the experimental group wore open fingers Velcro covered mittens. Training consisted of one 4-minute session of stimulated reaching using Velcro covered toys. Controls did not receive the training. During assessments, infants were placed in a baby chair and toys without Velcro were offered at their midline for 2 min. Number of total reaches, proximal adjustments and distal adjustments of reaching were primary outcomes. Grasping was a secondary outcome. RESULTS Groups were similar in the pretraining. In the posttraining, trained infants performed greater amount of total reaches and bimanual reaches than untrained infants. Greater amount of bimanual reaches in trained infants was maintained in the retention test. Distal adjustments and grasping outcome were not influenced by the training. CONCLUSIONS A brief-term training with open fingers sticky mittens benefited reaching behavior and favored retention of increased bimanual reaches in newly reaching late preterm infants. However, it was not sufficient to influence hand openness and early grasping.
