Frames of Reference & Developmental Theories

Neural Maturation

  • Motor Skills Development

    • Develops in a systematic order as the central nervous system matures.

    • Influencing factors: No Environmental Influence.

    • Reflexes

    • Serve as foundational elements for development.

  • Bobath (NDT)

    • Emphasizes a hierarchical progression of motor control.

    • Notes: Abnormal tone or reflexes can disrupt functional movement.

  • Sensory Integration

    • ROOD

    • Indicates that sensory stimulation influences motor responses based on motor control development.

    • Sensory inputs:

      • Tactile

      • Thermal

      • Proprioceptive

    • Poor sensory processing can hinder adaptive motor responses.

Cognitive: Behavioral

  • Development Influences

    • Driven by biology and shaped through experiences.

  • Watson (Classical Conditioning)

    • Behavior shaped through associations:

    • Stimuli evoke reflexive responses.

  • Skinner (Operant Conditioning)

    • Behavior shaped by consequences:

    • Reinforcement increases behavior

    • Punishment decreases behavior.

  • Compare Classical and Operant Conditioning

    • Classical Conditioning: Involuntary response paired with stimulus,

    • Operant Conditioning: Associates voluntary behavior and consequence.

Cognitive: Piagetian

  • Cognitive Development and Motor Exploration

    • Cognitive learning occurs through four stages:

    • Sensorimotor (0-2)

      • Object permanence

      • Knowledge through sensory experience.

    • Preoperational (2-7)

      • Symbolic thinking

      • Egocentric perspective.

      • Imaginative play with tools.

    • Concrete Operational (7-11)

      • Logical thinking about concrete events.

      • Improved coordination for multistep tasks.

      • Reasoning shifts from specifics to general principles.

    • Formal Operational (12+)

      • Abstract, hypothetical thinking,

      • visualized outcomes, and problem-solving skills.

Cognitive: Motor Learning

Task Types

  • Closed Task vs Open Task

    • Closed Task

    • Simple complexity,

    • Little internal variability,

    • No object manipulation.

    • Open Task

    • Higher complexity,

    • In motion,

    • Internal variability,

    • Involves object manipulation.

  • Learning Stages:

    • 1: Recall

    • 2: Recognition

    • 3: Adaptation.

Dynamic Systems Theory

  • Different Elements in Development

    • Acknowledges that various subsystems contribute equally to development.

  • Key Concepts:

    • Deviations may occur due to external influences.

    • Unique and non-transferable factors contribute to skill development.

    • Variety in movement patterns supports new skill challenges.

    • Limits in movement strategies can disadvantage children with disabilities.

  • Neuronal Group Selection Theory:

    • "Use it or lose it"

    • Distinguishes between "hardware" (neurons) and "software" (motor programs).

    • Repeated actions create responsive motor patterns.

    • Diverse activities encourage better differentiated responses.

  • Perception-Action Theory:

    • Movement enhances environmental understanding:

    • Nothing can be perceived without actions leading to learning about the environment.

  • Ecological Theory:

    • Movements are planned in relation to environment understanding.

Biological Model of Development

  • Views development as a reciprocal relationship between the child and environment.

Layered Context of Development:
  1. Individual Child:

    • Age, Diagnosis, Development Roles.

  2. Caregivers:

    • Parents, Pets, Physical Home Context.

  3. Family Context:

    • Siblings, Extended Family, Culture, Religious Contexts.

  4. Community:

    • Schools, Activities, Physical environments, Neighbors.

  5. Geopolitical Contexts:

    • Government Policies, Healthcare, IDEA, Climate Change.
