“…Delay in the development of fine motor skills has been VOLUME 4, 2016 found to be common in ASD, and is typically a better predictor of diagnosis than gross motor skills [3]. In children, this can manifest in degraded control during handwriting [4] [5] and drawing tasks [6]. Recent research has suggested that speech differences witnessed in ASD stem from the motor coordination and control deficits that are associated with facial and fine motor gestures in ASD [7].…”

Assessment of Speech and Fine Motor Coordination in Children With Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a developmental disorder characterized by difficulty in communication, which includes a high incidence of speech production errors. We hypothesize that these errors are partly due to underlying deficits in motor coordination and control, which are also manifested in degraded fine motor control of facial expressions and purposeful hand movements. In this pilot study, we computed correlations of acoustic, video, and handwriting time-series derived from five children with ASD and five children with neurotypical development during speech and handwriting tasks. These correlations and eigenvalues derived from the correlations act as a proxy for motor coordination across articulatory, laryngeal, and respiratory speech production systems and for fine motor skills. We utilized features derived from these correlations to discriminate between children with and without ASD. Eigenvalues derived from these correlations highlighted differences in complexity of coordination across speech subsystems and during handwriting, and helped discriminate between the two subject groups. These results suggest differences in coupling within speech production and fine motor skill systems in children with ASD. Our long-term goal is to create a platform assessing motor coordination in children with ASD in order to track progress from speech and motor interventions administered by clinicians.

“…In autism, we identify a fundamental disruption of the intuitive prospective motor control and its affective regulation in “vitality dynamics” (Fournier et al 2010; Stern 2010). There is an alteration in the subsecond kinematic patterns of intentional movement of the arms and hands (Trevarthen & Delafield-Butt 2013a), whether to swing the arms, reach to touch, swipe a tablet, or write a name (Anzulewicz et al 2016; Cook et al 2013; Dowd et al 2012; Grace et al 2018; Torres et al 2013).…”

Being misunderstood in autism: The role of motor disruption in expressive communication, implications for satisfying social relations

et al. 2019

Jaswal & Akhtar's outstanding target article identifies the necessary social nature of the human mind, even in autism. We agree with the authors and present significant contributory origins of this autistic isolation in disruption of purposeful movement made social from infancy. Timing differences in expression can be misunderstood in embodied engagement, and social intention misread. Sensitive relations can repair this.

“…In 2019, Giannini and co-workers have tried to elaborate a handwriting analysis protocol in order to estimate severe major depressive disorder, achieving encouraging results [66]. Grace et al investigate how children affected by autism spectrum disorder plan and control their handwriting actions [67]. The patients presented a breakdown in their ability to control and regulate their handwriting movements compared to the control group ant these outcomes represented implications for the school-aged child who were constantly involved in handwriting tasks within the classroom environment.…”

Handwriting analysis dates back to many centuries ago. Graphology is a discipline that investigates personality and intellect of the individual through writing, indeed handwriting of the human being is an expression of his or her essence. Graphology examines a writing in order to extract unfiltered information about innate temperament and subconscious nature of who has traced the letters. The present paper highlights the historical and methodological approaches of graphology and its usefulness in human knowledge in order to give a glimpse of the complexity of this discipline. We have gradually focused on the description of the various fields with which, over time until today, the graphologists have dealt according to experimental and epistemological methodologies along a spectrum that ranges from studies on the character, the neuronal and biological correlates, the use in the forensic field, until to the contributions to career counseling and personnel selection. This manuscript aims to provide a quantitative picture of the handwriting analysis trying to combine insights from different sources and exploring conditions, limits and possibilities of its subject matter and methods involved. Handwriting analysis draws reliable conclusions about the spirit personality of a writer. We suppose that graphology and psychology could complement each other, and in this perspective, we explore the hypothesis of the existence of a bidirectional relationship between psychology, graphology and neuroscience which allows to gain insight into ourselves and others.
