Sensorimotor Stage of Cognitive Development

Overview

• Age Range: From birth to approximately 2 years.
• Key Concept: Infants learn about the world through their senses and motor interactions.
• Developmental Focus: Infants use inborn abilities to explore the environment, facilitating rapid cognitive growth.

Piaget's Theory

• Jean Piaget: Proposed four stages of cognitive development.
• Sensorimotor Stage: First of four stages, characterized by sensory and motor interaction with the environment.

Substages of Sensorimotor Development

1. Reflexes (0-1 month):
   • Understanding the environment through innate reflexes like sucking.
2. Primary Circular Reactions (1-4 months):
   • Coordination of sensation with new schemas.
   • Example: Thumb sucking by accident, repeated because it is pleasurable.
3. Secondary Circular Reactions (4-8 months):
   • Intentional actions to provoke environmental responses.
   • Example: Picking up and mouthing toys.
4. Coordination of Reactions (8-12 months):
   • Intentional actions and beginning of object understanding.
   • Example: Shaking a rattle to hear the sound.
5. Tertiary Circular Reactions (12-18 months):
   • Trial-and-error experimentation.
   • Example: Trying different actions/sounds to attract attention.
6. Early Representational Thought (18-24 months):
   • Development of symbols to represent objects/events.
   • Move towards mental operations understanding.

Object Permanence

• Definition: Understanding that objects continue to exist even when not visible.
• Significance: A major cognitive milestone during the sensorimotor stage.
• Example: Peek-a-boo game illustrating early vs. developed object permanence.

Supporting Sensorimotor Development

• Caregiving Tips:
  • Provide responsive care to encourage cognitive growth.
  • Engage in play, conversation, and exploration with the child.
  • Offer sensory experiences and self-led play opportunities.
  • Use books with different textures to stimulate touch and sight.

Takeaways

• Importance: Sets foundation for subsequent cognitive stages.
• Developmental Outcomes: Leads to skills in language, imagination, and memory in later stages.
