The importance of playing in children’s psychomotor development

In contemporary society, there is a recurring tendency to view children's play as merely passive entertainment, a distraction or a moment of idleness in which the child is "not learning". However, under the lenses of clinical psychopedagogy, genetic psychology and developmental neurobiology, playing constitutes the most complex and vital work of childhood. It is through playful activity that the subject explores the physical environment, expresses his affectivity, builds cognitive schemes and develops his psychomotricity — the integrated basis on which all future symbolic and conceptual learning will be based.

"It is in playing, and only in playing, that the individual, child or adult, is capable of being creative and using his or her entire personality: and it is only by being creative that the individual discovers the self." —Donald Woods Winnicott (1971, p. 80)

Henri Wallon's Socio-affective Theory and the Movement

The understanding of human movement in childhood gained innovative contours with the formulations of Henri Wallon (1879-1962). In his psychogenetic theory, Wallon proposes an integrative view of child development, refusing the Cartesian separation between mind and body. For him, the development of the subject is supported by four inseparable pillars: the movement, the affection, the intelligence and the formation of the self (LOPES, 2019).

Movement, from a Wallonian perspective, is the first way of expression of the psyche. Before mastering verbal language, children communicate with the world and express their emotions through tonic dialogue, that is, through fluctuations in tension and muscle relaxation (tone). Emotions have an eminently corporal and social character. Movement is, therefore, the essential connector for the assimilation of knowledge, in which socio-affective interactions promote a dialectical syncretism — clashes of bodily and affective perspectives that generate healthy cognitive conflicts, propelling the child towards higher levels of intellectual development and the consolidation of their own identity.

Playing, Reality and Potential Space in Winnicott

While Wallon shows us the motor and socio-affective dynamics, the English pediatrician and psychoanalyst Donald Woods Winnicott (1896-1971) provides the framework for understanding playing as an existential and structuring phenomenon of the Self. Winnicott postulates that the baby initially develops in a state of fusion with the environment. For differentiation to occur between the "I" (subjective) and the "Not-I" (the objective world), the child needs an intermediate zone of experience, called potential space or transitional space.

In this space, symbolized by the use of transitional objects (like a teddy bear or a piece of fabric), the child experiences the illusion of creating the world, at the same time as discovering its factual reality. The act of playing, therefore, is not an alienating fantasy, but an active and creative experimentation with physical and social reality. Without experiencing this potential space provided by free play, the child can develop a "false Self", characterized by a mechanical submission to external demands, which generates serious psycho-pedagogical obstacles, such as intellectual inhibition and learning difficulties.

The Structural Elements of Psychomotricity

Psychomotricity is operationalized through specific neuropsychological elements that must be continuously stimulated in childhood. Weakness in any of these functions can have direct consequences on the formal learning of reading, writing and logical reasoning:

• Muscle Tone: The state of active tension of the muscles that supports postures and voluntary movement. Its regulation is essential to avoid fatigue when writing.
• Body Layout: The intuitive knowledge and immediate awareness that the child has of their own body in relation to space and objects, serving as a reference for action.
• Body Image: The subjective representation and the affective and social relationship that the child establishes with their own physical body, directly influencing their self-esteem and self-confidence.
• Laterality: The definition of cerebral hemispheric dominance that determines the preference for using one side of the body (hand, foot, eye and ear). Inadequate lateralization can lead to difficulties with orientation and mirrored writing.
• Spatio-Temporal Structuring: The ability to locate oneself in physical space and understand relationships of distance, direction and orientation, in addition to sequencing events in time (before, during and after). It is the basis for the ordering of letters in words and numbers in mathematical calculations.
• Global and Fine Praxis: Gross motor coordination (running, jumping, balancing) and the coordination of small muscle groups for precision tasks (holding a pencil, cutting, buttoning), fundamental for the development of writing and detailed academic skills.

Brain-Body Connection: The Neurobiology of Movement

Psychomotor development is not just a sequence of behavioral milestones; it reflects the maturation and myelination of complex neural circuits. When the child runs, jumps, balances or manipulates objects, he is intensely activating the primary motor cortex (responsible for planning and executing physical strength) and the cerebellum, a central organ that compares motor intention with actual execution, making millimetric corrections in real time, in addition to actively participating in temporal and cognitive coordination.

Games that involve spinning, swinging and sudden changes of direction stimulate the vestibular system (located in the inner ear), which detects the position of the head in space, and proprioceptive receptors (in muscles, tendons and joints), which inform the brain of the relative positioning of body parts. The harmonious integration of these sensory pathways in the brain stem and thalamus is essential for ocular stabilization, maintenance of postural tone and the ability to focus attention. Inadequate maturation of sensory integration It generates postural fatigue, motor agitation (a child who cannot sit in a chair) and inattention, often confused with ADHD.

Practical Implications of the Dimensions of Development

Below, we summarize the four dimensions of human development proposed by Wallon and their direct clinical and pedagogical implications for the development of learning:

Wallonian Dimension	Manifestation in Play	Direct Psychopedagogical Implication
Movement (Motricity)	Space exploration, body rules games, jumping, balance and manipulation of unstructured objects.	Neurological basis for writing, spatial representation and graphic organization on paper.
Affectivity	Expression of fears, desires, frustrations and achievements through symbolic play and make-believe.	Emotional availability to learn, tolerance for error and development of resilience in the face of challenges.
Intelligence (Cognition)	Solving practical problems, fittings, stacking, classifying pieces and game strategies.	Transition from concrete thinking to abstract thinking and logical-mathematical conceptualization.
Formation of the Self (Character)	Role-playing games (playing house, school, heroes), experimenting with different identities and otherness.	Subjective differentiation, body awareness, emotional security and strengthening academic self-concept.

Psychopedagogical Interventions: How to Stimulate Body Development?

In a time marked by early digitalization and the dramatic reduction of safe urban spaces, parents and educators must intervene intentionally to ensure psychomotor health:

1. Rescue of "Tempo de Chão" and Fewer Screens: Limit the time spent using smartphones and tablets, which keep the child physically inactive, encouraging free physical play that requires locomotion, rolling and balance.
2. Use of Unstructured Toys: Cardboard boxes, wooden blocks, fabrics, clay and elements of nature stimulate creative imagination (Winnicott) and demand greater fine and global motor planning (Wallon) than pre-programmed electronic toys.
3. Encouraging Traditional Games: Jumping rope, hopscotch, tag and dodgeball stimulate inhibitory control, eye-pedal coordination, space-time structuring, sudden tonic deceleration and collective socio-affective regulation.
