Computational analysis of infant movement has significant potential to reveal markers of developmental health. We report two studies employing dynamic analyses of motor kinematics and motor behaviours, which characterise movement at two levels, in 9-month-old infants. We investigate the effect of preterm birth (< 33 weeks of gestation) and the effect of changing emotional and social-interactive contexts in the still-face paradigm. First, multiscale permutation entropy was employed to analyse acceleration kinematic timeseries data collected from Inertial Measurement Unit (IMU) sensors on infants’ torso, wrists, and ankles (N = 32: 10 term; 22 preterm). Second, Recurrence Quantification Analysis was used to characterise patterns of second-to-second behavioural changes, from observationally coded behavioural timeseries on infants’ emotional self-regulation (N = 111: 61 term; 50 preterm). We found frequency-specific effects of context on permutation entropy. Relative to infants born at term (> 37 weeks of gestation), infants born preterm showed greater permutation entropy in their left ankle and torso movements, but not in right ankle or wrist movements. We did not find effects of preterm birth or emotional context on micro-level behavioural dynamics. Our methodology and findings inform future work using multiscale entropy to study infant development. Dynamic analysis of behaviour is a relatively young field, and applications to emotional self-regulation requires further methodological development.

We present a handbook for Rhythmic Relating, an approach developed to support play, learning and therapy with young autistic children, unconventional communicators, and autistic people who have additional learning needs. Rhythmic Relating is based on the Movement Sensing perspective, a growing body of research that recognizes that autistic social difficulties stem from more basic sensory and motor differences. These sensorimotor differences directly affect embodied experience and social timing in communication. The Rhythmic Relating approach acknowledges that autistic/non-autistic interactive mismatch goes both ways and offers bidirectional support for social timing and expressive action in play. This handbook is presented in an accessible fashion, allowing the reader to develop at their own pace through three skill-levels and encouraging time out to practice. We begin with the basics of building rapport (seeing, copying, and celebrating interactional behaviors), introduce the basic foundations of sensory stability, and then move on to developing reciprocal play (using mirroring, matching, looping, and “Yes…and” techniques), and further to understanding sensory impetus (using sensory contours, accents and flows) and its potential in support of social timing. Rhythmic Relating is offered in support of each practitioner’s creative practice and personal sense of fun and humor in play. The model is offered as a foundation for interaction and learning, as a base practice in schools, for Occupational Therapists, Speech Therapists and Physiotherapists, and can also provide a basis for tailoring creative arts therapies when working with autistic clients.

In this review, we look at recent work that examines the genesis of conscious awareness in utero in humans. We focus on observable behaviours that suggest a state of anticipatory perceptual awareness evident in the foetal period, and the foetus’ first expression of agency through self-generative engagement with it. This predictive, anticipatory awareness is first evident in the prospective sensorimotor organisation of bodily movements of the second trimester foetus, revealing an early adaptive awareness and agency that establishes the foundation for additional forms of abstract, reflective, and conceptually-backed conscious experience in adults. Improved understanding of these early sensorimotor foundations of psychological development and health affords an improved understanding adult human consciousness, the nature of its early ontogeny, and its particular expression mediated by the integrative nervous system.

Autistic individuals often exhibit motor atypicalities, which may relate to difficulties in social communication. This study utilized a smart tablet activity to computationally characterize motor control by testing adherence to the two-thirds power law (2/3 PL), which captures a systematic covariation between velocity and curvature in motor execution and governs many forms of human movement. Children aged 4-8 years old participated in this study, including 24 autistic children and 33 typically developing children. Participants drew and traced ellipses on an iPad. We extracted data from finger movements on the screen, and computed adherence to the 2/3 PL and other kinematic metrics. Measures of cognitive and motor functioning were also collected. In comparison to the typically developing group, the autistic group demonstrated greater velocity modulation between curved and straight sections of movement, increased levels of acceleration and jerk, and greater intra- and inter-individual variability across several kinematic variables. Further, significant motor control development was observed in typically developing children, but not in those with autism. This study is the first to examine motor control adherence to the 2/3 PL in autistic children, revealing overall diminished motor control. Less smooth, more varied movement and an indication of developmental stasis in autistic children were observed. This study offers a novel tool for computational characterization of the autism motor signature in children's development, demonstrating how smart tablet technology enables accessible assessment of children's motor performance in an objective, quantifiable and scalable manner.

We review recent work that examines the genesis of a prereflective self-consciousness in utero in humans. We focus on observable behaviours that suggest a state of anticipatory perceptual awareness evident in the foetal period and the foetus’ first expression of agency through self-generative engagement with it. This predictive, anticipatory awareness is first evident in the prospective sensorimotor organisation of bodily movements of the second-trimester foetus, revealing an early adaptive awareness and agency that establishes the foundation for additional forms of abstract, reflective, and conceptually backed conscious experience in adults. Advanced understanding of these early sensorimotor foundations of psychological development and health may afford a better understanding of adult human consciousness, the nature of its early ontogeny, and its particular expression mediated by the integrative nervous system.

Emotional self-regulation involves different systems (such as motor, attentional and cognitive) interacting in time to influence emotional behaviour and physiology. We investigated differences in emotional self-regulation during the still-face paradigm in 111 9-month-old infants (61 term; 50 preterm, <33 weeks of gestation), in the amount of emotional self-regulatory behaviours, as well as the micro-level (obtained using recurrence quantification analysis) and macro-level behavioural dynamics (differences under repeated stress). Preterm birth was associated with fewer repetitive movements, and lower gestational age increased this effect. Unlike that of term-born infants, the behaviour of preterm-born infants changed under repeated stress, leading to fewer object-oriented attentional distraction strategies, fewer repetitive movements, and greater oral-tactile self-comforting strategies. No differences in micro-level behavioural dynamics, or socially-oriented regulatory behaviours were found. Prematurity results in greater regulatory “brakes” on emotional expression with repetitive movements, and emotional self-regulatory capacities may be more vulnerable to the nature of environmental stress.

Neuropsychiatric and neurodevelopmental disorders are often associated with coordination problems. Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) constitutes a specific example of acute and complex symptomatology that includes difficulties with motor control. The present proof-of-concept study aimed at testing a new, bespoke tablet-based motor coordination test named SpaceSwipe, providing fine-grained measures that could be used to follow-up on symptoms evolution in PANS. This test enables computationally precise and objective metrics of motor coordination, taking into account both directional and spatial features continuously. We used SpaceSwipe to assess motor coordination in a group of children with PANS (n = 12, assessed on in total of 40 occasions) and compared it against the motor coordination subtest from the Beery-Buktenica Developmental Test of Visual-Motor Integration (Beery VMI) 6th edition, traditionally used to follow-up symptomatology. Using a bivariate linear regression, we found that 33 s of the directional offset from tracking a moving target in SpaceSwipe could predict the Beery VMI motor coordination (VMI MC) raw scores (mean absolute error: 1.75 points). Positive correlations between the predicted scores and the VMI MC scores were found for initial testing (radj = 0.87) and for repeated testing (radj = 0.79). With its short administration time and its close prediction to Beery VMI scores, this proof-of-concept study demonstrates the potential for SpaceSwipe as a patient-friendly tool for precise, objective assessment of motor coordination in children with neurodevelopmental or neuropsychiatric disorders.

Since the publication of Meltzoff and Moore's seminal paper, neonatal imitation has been discussed, debated, and scrutinised at considerable length. Despite this, the temporal structure within which the interaction sits, has received limited attention. We hypothesise underlying successful examples of neonatal imitation exists a narrative temporal structure, expressed and perceived not only through vocalisations but also (if not primarily) through movement. We contextualise neonatal imitation through a communicative lens, viewing the phenomenon as an early dialogue between adult and infant, underpinned by the same narrative structure as other "proto-conversations" in infancy. From this perspective, several of the leading and traditional theories that have been proposed to explain neonatal imitation are considered. Ultimately, we argue neonatal imitation is an innately dialogical phenomenon that forms one of the first examples of primary intersubjectivity, exemplifying the importance of the neonatal period in human psychological and social development. On this basis we propose further study is required into the temporal structure underlying neonatal imitation.

Autism spectrum disorder (ASD) and Developmental Coordination Disorder (DCD) are distinct clinical groups with overlapping motor features. We attempted to (1) differentiate children with ASD from those with DCD, and from those typically developing (TD) (ages 8-17; 18 ASD, 16 DCD, 20 TD) using a 5-min coloring game on a smart tablet and (2) identify neural correlates of these differences. We utilized standardized behavioral motor assessments (e.g. fine motor, gross motor, and balance skills) and video recordings of a smart tablet task to capture any visible motor, behavioral, posture, or engagement differences. We employed machine learning analytics of motor kinematics during a 5-min coloring game on a smart tablet. Imaging data was captured using functional magnetic resonance imaging (fMRI) during action production tasks. While subject-rated motor assessments could not differentiate the two clinical groups, machine learning computational analysis provided good predictive discrimination: between TD and ASD (76% accuracy), TD and DCD (78% accuracy), and ASD and DCD (71% accuracy). Two kinematic markers which strongly drove categorization were significantly correlated with cerebellar activity. Findings demonstrate unique neuromotor patterns between ASD and DCD relate to cerebellar function and present a promising route for computational techniques in early identification. These are promising preliminary results that warrant replication with larger samples.

Joint action, generally defined as working together towards a common purpose, has become an important concept in many areas of cognitive science, from philosophical appraisal of its core concepts to empirical mapping of its psychological development. Within mainstream cognitive accounts, to engage in a joint action requires an inferential process of representing the other’s intentions and plans to enable social coordination for a shared goal. However, growing endorsement of a contrasting view from embodied and situated accounts of social cognition proposes that joint action is better understood as a dynamic, situated interactional process where participants “roll into” joint action without requiring reflective or representational awareness of it. This work proposes a rethinking of how we conceive the nature of action and its development as joint action early in human life. With particular reference to developmental studies, we advance a rationale for the conceptual framework of joint action to include its temporal and sequential structures, and their intrinsic prospective qualities of human action, solitary or shared, as key analytical aspects for the study of how infants understand and share meaning with another, in joint interaction.

We propose Rhythmic Relating for autism: a system of supports for friends, therapists, parents, and educators; a system which aims to augment bidirectional communication and complement existing therapeutic approaches. We begin by summarizing the developmental significance of social timing and the social-motor-synchrony challenges observed in early autism. Meta-analyses conclude the early primacy of such challenges, yet cite the lack of focused therapies. We identify core relational parameters in support of social-motor-synchrony and systematize these using the communicative musicality constructs: pulse; quality; and narrative. Rhythmic Relating aims to augment the clarity, contiguity, and pulse-beat of spontaneous behavior by recruiting rhythmic supports (cues, accents, turbulence) and relatable vitality; facilitating the predictive flow and just-ahead-in-time planning needed for good-enough social timing. From here, we describe possibilities for playful therapeutic interaction, small-step co-regulation, and layered sensorimotor integration. Lastly, we include several clinical case examples demonstrating the use of Rhythmic Relating within four different therapeutic approaches (Dance Movement Therapy, Improvisational Music Therapy, Play Therapy, and Musical Interaction Therapy). These clinical case examples are introduced here and several more are included in the Supplementary Material (Examples of Rhythmic Relating in Practice). A suite of pilot intervention studies is proposed to assess the efficacy of combining Rhythmic Relating with different therapeutic approaches in playful work with individuals with autism. Further experimental hypotheses are outlined, designed to clarify the significance of certain key features of the Rhythmic Relating approach.

We review evidence of non-verbal, embodied narratives in human infancy to better understand their form and function as generators of common experience, regulation, and learning. We examine their development prior to the onset of language, with a view to improve understanding of narrative as regular motifs or schemas of early experience in both solitary and social engagement. Embodied narratives are composed of regular patterns of interest, arousal, affect, and intention that yield a characteristic four-part structure of (i) introduction, (ii) development, (iii) climax, and (iv) resolution. Made with others these form co-created shared acts of meaning, and are parsed in time with discreet beginnings and endings that allow a regular pattern to frame and give predictive understanding for prospective regulation (especially important within social contexts) that safely returns to baseline again. This characteristic pattern, co-created between infant and adult from the beginning of life, allows the infant to contribute to, and learn, the patterns of its culture. We conclude with a view on commonalities and differences of co-created narrative in non-human primates, and discuss implications of disruption to narrative co-creation for developmental psychopathology.

Consciousness directs the actions of the agent for its own purposive gains. It re-organises a stimulus-response linear causality to deliver generative, creative agent action that evaluates the subsequent experience prospectively. This inversion of causality affords special properties of control that are not accounted for in integrated information theory (IIT), which is predicated on a linear, deterministic cause-effect model. IIT remains an incomplete, abstract, and disembodied theory without explanation of the psychobiology of consciousness that serves the vital agency the organism.

This paper describes a smart tablet-based drawing app to digitally record participants’ engagement with the Rey-Osterrieth complex figure (ROCF) task, a well-characterised perceptual memory task that assesses local and global memory. Digitisation of the tasks allows for improved ecological validity, especially in children attracted to tablet devices. Further, digital translation of the tasks affords new measures, including accuracy and computation of the fine motor control kinematics employed to carry out the drawing Here, we report a feasibility study to test the relationship between two neurodevelopmental conditions: autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). The smart tablet app was employed with 39 adult participants (18-35) characterised for autistic and ADHD traits, and scored using the ROCF perceptual and organisational scoring systems. Trait scores and conditions were predictor variables in linear regression models. Positive correlations were found between the attention-to-detail, attention-switching and communication subscales of the autistic trait questionnaire and organisational scores on the ROCF task. These findings suggest that autistic traits might be linked to differential performance on the ROCF task. Novelty and future applications of the app are discussed.

The motor system is becoming increasingly recognized as an important site of disruptions in autism spectrum disorders (ASD). However, the precise nature of this motor disruption remains unclear with some conflicted reports between papers. A bottleneck in kinematic studies of children with ASD has been the use of laboratory-based motion tracking systems and experimental paradigms that require didactic instructions. Thus, we employed an attractive smart tablet gameplay methodology to engage children’s interest without complicated verbal instruction. Children’s movements on the touch screen were recorded as they engaged in gameplay of their own volition, enabling improved ecological validity in data capture. Swipe kinematics were computed from two games that afforded goal-directed and free-style scribbling, respectively. 82 children aged 2-6 years were tested, including 37 children with ASD and 45 typically developing (TD) children. Kinematic analyses revealed significant age, group, and task differences. In comparison to aged-matched TD children, children with ASD under 5 years old performed faster goal-directed movements, whereas those over 5 years old performed slower goal-directed movements. In contrast, children with ASD moved faster than TD children irrespective of age during creative scribbling. Interestingly, movement speed increased with age in TD children in both game contexts, likely due to motor skill and confidence development, but this was not true for children with ASD, who moved slower in the case of goal-directed swipes or with no difference in the case of creative scribbling. These findings support emerging evidence for differences in maturation of visuomotor integration in preschool children with ASD.

This article offers a neuroscientific explanation of the experience of autism as a disruption to the embodied experience of the Core Self. It recognizes human experience is integrative by nature. Attending to the insights of Penelope Dunbar (Pum), who has lived with autism for decades, we explore an affective neuroscience understanding of autistic experience as a disruption to embodiment and coherence of the Core Self, and how to work creatively with its impulses for health and personal development. Pum describes her autistic disruptions to the intra-personal coherence of her basic states of being, moving-with-feeling in self-awareness, and how this disturbance to her internal subjective coherence of mind challenges her capacity to self-regulate arousal, and communicate with others. By examination of the source of her problems in childhood and ways of working with them, Pum has clarified fundamental elements in the development of her capacity to regulate self-care in creative efforts that facilitate both affective embodiment and sensory-motor coherence in growth of understanding in her mind and body. With her advice, we explore how current neurobiological insights in autism as a disruption to the regulation of affective embodiment and sensory-motor integration leads to new recommendations for therapeutic care to relieve autistic distress and restricted modes of being. Although particular to her circumstances and cultivated habits of autistic expression, this analysis offers insight into the fundamental nature of autism, and ways of positive working with one's autism for creative gains.

Movement is prospective. It structures self-generated engagement with objects and social partners and is fundamental to children’s learning and development. In autistic children, previous reports of differences in movement kinematics compared to neurotypical peers suggest its prospective organisation might be disrupted. Here, we employed a smart tablet serious game paradigm to assess differences in the feedforward and feedback mechanisms of prospective action organisation, between autistic and neurotypical preschool children. We analysed 3926 goal-directed finger movements made during smart-tablet ecological gameplay, from 28 children with Childhood Autism (ICD-10; ASD) and 43 neurotypical children (TD), aged 3-6 years old. Using linear and generalised linear mixed-effect models, we found the ASD group executed movements with longer Movement Time (MT) and Time to Peak Velocity (TTPV), lower Peak Velocity (PV), with peak velocity less likely to occur in the first movement unit, and with a greater number of Movement Units After Peak Velocity (MU-APV). Interestingly, compared to the TD group, the ASD group showed smaller increases in PV, TTPV and MT with an increase in Age (ASD x Age interaction), together with a smaller reduction in MU-APV and an increase in MU-APV at shorter target distances (ASD x Dist interaction). Our results are the first to highlight different developmental trends in anticipatory feedforward and compensatory feedback mechanisms of control, contributing to differences in movement kinematics observed between autistic and neurotypical children. These findings point to differences in integration of prospective perceptuomotor information, with implications for embodied cognition and learning from self-generated action in autism.

Most theoretical and empirical discussions about the nature of consciousness are typically couched in a way that endorses a tacit adult-centric and vision-based perspective. This paper defends the idea that consciousness science may be put on a fruitful track for its next phase by examining the nature of subjective experiences through a bottom-up developmental lens. We draw attention to the intrinsic link between consciousness, experiences and experiencing subjects, which are first and foremost embodied and situated organisms essentially concerned with self-preservation within a precarious environment. Our paper suggests that in order to understand what consciousness 'is', one should first tackle the fundamental question: how do embodied experiences 'arise' from square one? We then highlight one key yet overlooked aspect of human consciousness studies, namely that the earliest and closest environment of an embodied experiencing subject is the body of another human experiencing subject. We present evidence speaking in favour of fairly sophisticated forms of early sensorimotor integration of bodily signals and self-generated actions already being established in utero. We conclude that these primitive and fundamentally relational and co-embodied roots of our early experiences may have a crucial impact on the way human beings consciously experience the self, body and the world across their lifespan.

Empirical evidence suggests game-based learning (GBL) as a potentially engaging form of contemporary learning. With the increase in the use of Minecraft, a sandbox computer game in open-world format, there has been a concurrent rise in the level of interest in investigating the role of Minecraft in social and academic learning. Minecraft is socially interactive, and its cooperative, rather than competitive, open-world gameplay suggests that it could be used for educational purposes. This paper presents a systematic review of all published peer-reviewed research and synthesises the evidence for and against Minecraft's use in education to better understand the applicability of Minecraft in educational and psychological interventions. Forty-two papers were identified. These revealed Minecraft to be beneficial in terms of increased motivation, language development, and academic learning in subjects such as science and history. Minecraft play also supported the development of social skills, including communication, sharing, collaboration, and leadership. Concerns about age-appropriateness, safety, technology use, and learning generalisation were raised, but on balance, the evidence favours an informed and guided employment of Minecraft for improved opportunities for learning and engagement in education.
