Psychomotor Development: Stages, Laws, and Body Schema

Psychomotor Development: Knowledge and Expression

Psychomotor development is the primary source of knowledge and the expression of our understanding. According to Vayer, education must be comprehensive and rooted in lived psychomotor experiences.

Maturation and Motor Control

Development begins with involuntary responses, progressing through the maturation of nerve fibers and centers toward conscious, voluntary movements. This evolution follows specific patterns:

• Reflexive stage: Automatic, innate, and involuntary responses.
• Voluntary stage: Willful and deliberate motor acts.
• Habit formation: Automatic movements developed through mental representation.

Fundamental Laws of Motor Maturation

• Cephalocaudal Law: Control begins at the head and moves toward the trunk and lower limbs.
• Proximodistal Law: Control develops from the center of the body outward to the extremities (gross motor skills precede fine motor skills).

Body Schema and Mental Representation

A child's mental representation is defined by their body, its possibilities, and its limitations. This involves the elaboration of gestures and the correction of unnecessary movements, influenced by the physical and emotional environment.

Evolution of Self-Awareness (0 to 13 Years)

• Birth to 6 months: Fragmented self-image; inability to distinguish 'I' from 'not-me'.
• 6 months: Emergence of unity and wholeness.
• 2 to 3 years: Increased independence, feelings of competence, and the development of self-image.
• 3 years: Use of the pronoun 'I' and integration of the body schema through drawing.

Components of Body Schema

1. Interoceptive sensations: Information regarding physiological needs.
2. Proprioceptive sensations: Feedback on motor activity, control, and knowledge of body parts.
3. Exteroceptive sensations: Knowledge of the external world through the senses.

Tonic Control

Tonicity refers to the degree of tension required by muscles to perform an action or maintain a posture. Early development is characterized by hypertonia in the limbs and hypotonia in the body axis, which matures through emotional and relational experiences following the cephalocaudal and proximodistal laws.
