Development is dynamic, unique to each child, and discontinuous--with progressions and regressions. Control parameters may include factors at different levels and on different timescales. Dynamic systems theories consider development as a probabilistic outcome of the interaction of processes at many levels and many systems. Darrah, J., Redfern, L., Maguire, T. O., Beualne, A. P., & Watt, J. individual, task, and environment) that influence the emergence of behavior. Psychologists and other theorists have proposed a number of different theories centered on how children develop. The kinds of systems pictured in Fig. Simmering, in Advances in Child Development and Behavior, 2017. This suggests that movement is not developed in a continuous manner, at a steady rate. The four theories relating to child development I chose for discussion are Bronfenbrenner’s Ecological Systems Theory, Piaget’s Theory of Cognitive Development, Vygotsky’s Sociocultural Theory, and Erikson’s Psycho-Social Theory of Development. How do the neural processes, brain-wide dynamics, and movement that are involved in the behavioral decisions children make on a daily basis create developmental change? Physiotherapy services also aim to promote long-term health and prevent further impairments as the child grows and changes (Bartlett & Palisano, 2000). Second, development is a dynamic process: the interactants at one stage are the products of earlier stages of development. In addition, a study by Law et al. Thus, dynamic systems principles and methods afford opportunities to deepen conceptualization and empirically based knowledge of family influence processes. Esther Stillman Thelen, a developmental psychologist who applied dynamic systems theory, popularly called “chaos theory,” to the study of how babies learn to walk and interact, has died. A child is a seen as an organized system, with many subsystems such as perception, action, memory, language, social interaction, and so on. Darrah, J., & Bartlett, D. (1995). A focus on the latency phase is used to illustrate how theory and developmental research have influenced our psychoanalytic views of development over the past hundred years. From a dynamic systems perspective, individual difference factors, contextual factors, and metacognitive factors are all control parameters that may push the system toward or away from particular attractor states. He claimed that the child development is affected by their surrounding environment. An increasing popular view in developmental psychology that has been used to understand how developmental changes emerge is the Dynamic Systems Approach (DSA) (e.g., Thelen and Smith, 1994; Lewis, 2011; Molenaar et al., 2014; Blumberg et al., 2017). Children are shown a cutout of a white bird, which is then covered by a blue filter, and they are asked what color the bird is really (white), and what color does it appear when viewed through the filter (blue). Thus, despite the language of dynamic “attractors,” and reference vaguely to the process that moves the system along, the process that impels development is not specified. A. S., & Fogel, A. Thus, we turn to a discussion of the Piagetian A-not-B error as an influential and historically important application of DST. Developmental change, however, happens in between lab visits via massive quantities of real-time processes that occur across multiple levels. In its contemporary formulation, the theory grows directly from advances in understanding complex and nonlinear systems in physics and mathematics, but it also follows a long and rich tradition of systems … That is, they realize that when you take both height and width into account, quantity remains constant, or is ‘conserved’. Daniel Messinger, Jacquelyn Moffitt, in Encyclopedia of Infant and Early Childhood Development (Second Edition), 2020. Therapists need more clinical tools to measure variability, and guidelines around what amount of variability is optimal, and what indicates readiness to change. Thus, dynamic systems theories are well suited to conceptualize the interactions of multiple factors in processes of strategy change. Developmental systems theory (DST) is an overarching theoretical perspective on biological development, heredity, and evolution. This development is spontaneous and is not usually taught. Funding for Karen Sauve's Masters thesis was provided by Canadian Institutes of Health Research and the University of British Columbia. ages of dynamic systems theory according to which motor development is a product of the interplay between brain structure, the structure and dynamics of the body, and the structure of the environment. Law, M., Darrah, J., Pollock, N., King, G., Rosenbaum, P., Russell, D., Palisano, R., Harris, S., Armstrong, R., & Watt, J. As a representative example, consider mathematical equivalence problems with addends on both sides of the equal sign (e.g., 3 + 4 + 6 = 3 + __). A number of microlevel factors/mediating mechanisms such as temperament, callous/unemotional traits, and attributional bias have been identified as factors that potentially impact the development and maintenance of disruptive behavior problems; we refer readers to chapters in this book for a comprehensive review of these microlevel factors (see Chapters 5–8Chapter 5Chapter 6Chapter 7Chapter 8: Negative affect, Callous–unemotional traits, Cognitive attribution bias, and Sensation seeking and risk-taking, respectively). Is the learner highly confident that a particular strategy is correct?). Dynamic Systems Theory (DST) is a theory of motor development that can be applied to the management of children with Cerebral Palsy (CP; Darrah & Bartlett, 1995). Strengths and limitations of dynamic systems theory are reviewed. Dynamic systems theory (DST) outlines three constraints (i.e. The last foundational concept is the nesting of timescales. Historical geological factors that act over periods of time also help to shape present-day patterns. Dynamic systems theory (development and evolution) Posted by Brian Hopkins May 22, 2019. The relation between these two is influenced by a third variable, the viewing condition, such as whether the object is viewed directly or through a colored filter. The effectiveness of community participation on body functions, COVID-19 supports for people with disabilities and caregivers. Thus, clinicians need to consider and evaluate all aspects of the task, person, and environment when trying to help a child learn a new motor ability. This work illustrated the parallel between motor and cognitive development and, critically, their inseparability. Please browse our FAQ page for more information. Dynamic systems theory addresses the process of change and development, rather than developmental outcomes; in dynamic systems terms, there is no end point of development (Thelen & Ulrich, 1991). The clinical implications of dynamic systems theory in contrast with learnability theory are discussed, especially in the context of target selection decisions for … Please browse our FAQ page for more information. Understanding that the quantity remains constant typically develops spontaneously, and often appears quite suddenly, so that in a short time the child might switch from being sure that the quantity increases to being sure that it is constant. As an illustration, a mother and her adolescent might have a fairly close relationship, but there may be periods of more or less closeness; that is, the system may oscillate back and forth past its baseline level of closeness. Physical & Occupational Therapy in Pediatrics, 24(4), 63-78. Thelen, E. (1989). This illustrates the self-regulating nature of cognitive development. A second foundational concept is self-organization. Are there certain qualities or characteristics in a child that might influence their readiness to learn new motor abilities, such as motivation? Self-organization is related to a collection of additional DST concepts. An example of a dynamic system would be children’s acquisition of the concept of conservation, considered earlier. Dynamic systems theory and management of children with cerebral palsy: Unresolved issues. According to Miller (2002), dynamic systems theory is the broadest and most encompassing of all the developmental theories‍‍‍‍‍‍. They deviate because, even when the initial conditions in a system and the rules of the mechanisms at play are known, the system always contains an element of uncertainty. DST also suggests that motor development is non-linear, and that there are "peaks and valleys". First, to understand the origin of novelty in development. Children of 3–4 years of age typically think that, when liquid is poured from a short and wide to a tall and narrow vessel the quantity increases, because they see the large increase in height. We use cookies to help provide and enhance our service and tailor content and ads. (2004). Dynamic systems theory offers powerful concepts and tools both to capture the stability of behavior over time and to explain why a young child reads better for his parents than his teacher. Furthermore, dynamic system theorists recognize that the developmental outcomes being seen in the here-and-now are the product of pervasive current and historical patterns which continuously influence and co-construct the present. T he That is, the developmental process is viewed as change within a complex dynamic system. Dynamic systems theories, based on thermodynamic principles, deviate from the assumptions of strict causal explanation, in one sense at least. DST applications within psychological science have not been unitary. Every person in a family is unique. Patterns of behavior are not specified in advance, but instead, they are “softly assembled” in the moment, depending on the specifics of the task, the context and setting, and the immediate and developmental history of the individual. These variables are also related to observations that nothing was added when the liquid was poured, and that it would be same again if poured back. The goals of pediatric rehabilitation are ultimately to promote the child's safe participation in his or her home, school, and community environments, while learning functional activities (Russell, 2005). The outcomes of development are explained at the systems level, and developmental is influenced by the context in which it unfolds, leading to an extensive conception of that system. It is with the help of more knowledgeable others that people are able to progressively learn and increase their skills and scope of understanding. Importantly, such models can be used to make predictions about performance and change that can then be put to empirical test. Thelen was also president of the Society for Research in Child Development and the International Society for Infant Studies. The strong claim of DST is that these timescales create each other. theory of motor development that can be applied to the management of children with Cerebral Palsy (CP; Darrah & Bartlett Please note that CanChild is not a clinic for children and youth with developmental conditions. Further, systems are defined as either integrated or composite and are said to be made up of elements that are organized into structures of one or another hypothesized type (e.g., fractals, trajectories, cycles), that are acted upon by hypothesized processes that move the systems from one state to the next. Developmental Medicine & Child Neurology, 38, 226-237. Please contact: Karen Sauve at ksauve@cw.bc.ca. Evidence also shows us that there is variability in development. In this chapter, we present a theory of development based on very general and content-independent principles that describe the behavior of complex physical and biological systems. b. Stergiou, N., Harbourne R. T., & Cavanaugh, J. T. (2006). Moreover, family relationships may be self-regulating, with tendencies to return to baseline levels of functioning. Therapy can then be provided in an intensive burst, promoting new motor abilities when the child is most ready to acquire them. Copyright Dynamic Systems Theory: A Framework for Exploring Readiness to Change in Children with Cerebral Palsy, Improved motor outcomes during intensive bursts (Bower & McLellan, 1992; Schreiber, 2004; Trahan & Malouin, 2002), Maintenance of motor abilities or even continued improvements in motor outcomes during rest breaks as the child can practice the new abilities in various settings (Bower & McLellan, 1992; Schreiber, 2004; Trahan & Malouin, 2002), Improved communication between therapists and families (Trahan & Malouin, 2002), Promotion of family-centred care (Trahan & Malouin, 2002). Technically, a dynamic system is a formal system the state of which depends on its state at a previous point in time. Nevertheless, it is not often the case that such processes are specified. These factors converge for any given individual at any particular moment—sometimes in nonadditive, nonlinear ways—to yield behavior that (usually) aligns with a patterned form of behavior that is recognizable as use of a particular strategy. There remain several unanswered questions about this. What does DYNAMICAL SYSTEMS THEORY mean? DST asserts that human development must be conceptualized as the “multiple, mutual, and continuous interaction of all the levels of the developing system, from the molecular to the cultural” (Thelen & Smith, 2006, p. 258). We come from the “Bloomington camp” associated with Thelen and Smith, and therefore primarily present examples from this “family” of researchers. Dynamic systems theory has also influenced our thinking about the hierarchical organization of families and of time, as well as our conceptualizations of change.

This child development theory also introduced the concept of the zone of proximal development, which is the gap between what a person can do with help and what they can do on their own. Relatedly, broad-based contextual and systematic considerations such as social determinants of health have also been studied to inform how elements of broad factors (e.g., housing) impact and how disruptive behavior problems develop, and these macro factors/social determinants are the focus of the remainder of the chapter. Intra-individual stability of rate of gross motor development in full-term infants.
