“…Indeed, the way these behaviors are studied and measured highlights their separateness. Motor development researchers typically study sitting in infants planted on a force platform or kept in one place for normative assessment or monitoring of postural sway or muscle activity (Harbourne & Stergiou, 2003; Hedberg, Carlberg, Forssberg, & Hadders-Algra, 2005; Piper & Darrah, 1994; Rachwani et al, 2013). If infants fall over or try to escape, the trial is stopped.…”

A new twist on old ideas: how sitting reorients crawlers

Traditionally, crawling and sitting are considered distinct motor behaviors with different postures and functions. Ten- to 12-month-old infants were observed in the laboratory or in their homes while being coaxed to crawl continuously over long, straight walkways (Study 1; N = 20) and during spontaneous crawling during free play (Study 2; N = 20). In every context, infants stopped crawling to sit 3-6 times per minute. Transitions from crawling to sitting frequently turned infants’ bodies away from the direction of heading; subsequent transitions back to crawling were offset by as much as 180° from the original direction of heading. Apparently, body reorientations result from the biomechanics of transitioning between crawling and sitting. Findings indicate that sustained, linear crawling is likely an epiphenomenon of how gait is studied in standard paradigms. Postural transitions between crawling and sitting are ubiquitous and can represent a functional unit of action. These transitions and the accompanying body reorientations likely have cascading effects for infants’ exploration, visual perception, and spatial cognition.

“…The degree of antigravity control of flexors in supine seems to be more prominent in explaining the variability (35%) of later motor performance than antigravity extensor control (3%). Studies on postural control in normally developing children point at intricate control of flexors rather than extensors (21,22), suggesting that the control of flexors could be more susceptible to impairment (23 Á25).…”

The aim of the study was to relate motor outcome in very low birth weight (VLBW) infants at 5.5 years to motor performance at 5 months with special emphasis on children with poor motor performance at 5.5 years and children diagnosed with cerebral palsy (CP). A modified version of the Motor Assessment of Infants (MAI) was used at the corrected age of 5 months, and at 5.5 years the children's motor behaviour was followed up using the Movement ABC. Significant differences in motor behaviour of children who at 5.5 years developed normal, borderline or poor motor behaviour were seen at 5 months. In general, motor behaviours at 5 months and 5.5 years correlated. Only volitional movements, however, could predict motor outcome at 5.5 years. Within the group of children with ''poor'' motor performance, children with CP were recognized by a significantly higher score on the tone items of the MAI.

This paper gives an overview of the REsponsive FLExible Collaborating ambienT (REFLECT) project, concerning the developing of new concepts and means for pervasive-adaptive systems. Reflective approach combines different know-how in affective and physiological computing, software engineering, physics and pragmatic expertise into a unique endeavour to design and develop user-centric systems that control the specific environment and react relative to users' emotional, cognitive and physical situation. The central philosophy is to mimic the natural process of adaptation by implementing a biocybernetic loop that senses, diagnoses and analyses the user situation in a concrete settings and react accordingly. In a pervasive manner, the approach effectively brings system adaptation into real-life applications, making them sensitive and reactive to human inner states and behaviours. To show how these concepts have been put into practice, the document describes in detail how the seat adaptation system of the "REFLECTive Comfort Loop" has been developed for in an automotive environment.
