Understanding the Sensorimotor Stage

The sensorimotor stage, as proposed by Jean Piaget, is the first of four stages of cognitive development. This stage typically lasts from birth to approximately 2 years of age and is characterized by how infants interact with the world through their senses and motor actions.

Key Concepts of the Sensorimotor Stage

1. Object Permanence:

   • This is the understanding that objects continue to exist even when they cannot be seen, heard, or touched. It is a fundamental milestone within this stage.

2. Symbolic Thinking:

   • This development involves understanding that one thing can represent another, such as using a word or a figure to symbolize something else, which emerges later in the preoperational stage.

3. Egocentricity:

   • This refers to the inability to see situations from perspectives other than one's own, which is more characteristic of the preoperational stage.

4. Abstract Thinking:

   • This type of thinking refers to concepts that are not tied to concrete objects, which develops during later stages of cognitive development.

Given these definitions and characteristics associated with the sensorimotor stage, the hallmark of this stage is most accurately defined by:
