Cognitive Development Ages 2-6: Preoperational Stage

Substage 1: Symbolic and Preconceptual Thought (2-4 Years)

Cognitive Development: This period sees an enhanced capacity for mental representation, allowing reality to be symbolized through significant features and behaviors, moving beyond purely sensorimotor actions.

Key Features and Behaviors:

  • Preconcepts: These are the child’s initial concepts, heavily tied to concrete, specific examples rather than abstract categories. Evocations relate to particular objects the child has experienced. They struggle to identify essential similarities across all objects within a concept, focusing instead on superficial resemblances. This limitation arises because:
    • They cannot consistently recognize identical objects as the same when observed in different locations or at different times. Example: A child with a pet turtle at home sees another turtle in a field and identifies it as ‘my turtle’.
    • They struggle to maintain the identity of objects that undergo perceptual changes. Example: A child might momentarily fail to recognize their mother after a significant haircut, needing confirmation through touch or familiar gestures.
  • Transductive Reasoning: Children reason from particular to particular, establishing connections between specific events or objects based on proximity or perceived similarity, rather than using deductive (general to specific) or inductive (specific to general) logic.

Substage 2: Intuitive Thought (4-7 Years)

Cognitive Evolution: Coordination of representational relationships improves. Reasoning becomes more sophisticated but remains largely ‘intuitive’ as it is based on perception rather than logic, showing only a progressive, incomplete move towards reversibility.

Key Characteristics and Behaviors:

  • Acquisition of Invariants: The understanding of identities and functions begins to develop.

    Invariants are the essential qualities of an object that allow it to be recognized as itself, despite changes in non-essential qualities. Example: A table is recognized as such (a horizontal surface at a certain height) whether it’s high, low, white, brown, wooden, or plastic. Objects possess two kinds of qualities:

    • Essential: Precise qualities necessary to differentiate the object.
    • Non-essential: Qualities that can vary (e.g., color, size).

    This leads to the development of:

    • Identities: The child grasps that an object remains the same object even if its appearance changes superficially. They establish the notion of identity but cannot yet grasp quantitative invariance (conservation). Example: Recognizing the same pair of glasses despite changes in location.
    • Functions: The child can understand qualitative functional relationships between two events – recognizing that one thing can cause or depend on another in a predictable way. Example: Understanding the relationship between turning a key and a toy starting to move.

General Characteristics of Preoperational Thought (Ages 2-7)

  • Egocentrism: Difficulty differentiating one’s own perspective (physical or mental) from that of others; assuming others see, think, and feel the same way they do.
  • Centration: The tendency to focus on only one salient aspect of a situation or object at a time, neglecting other important features. This hinders logical thinking, particularly in conservation tasks.
  • Syncretism: A tendency to link unrelated events or ideas into a confused whole, often based on subjective impressions rather than logical analysis.
  • Juxtaposition: Placing ideas or events side-by-side without establishing logical causal or sequential relationships between them.
  • Irreversibility: The inability to mentally reverse a sequence of events or a process of reasoning back to its starting point.

Symbolic Function

A key achievement of the preoperational stage is the development of the symbolic function: the capacity to use one thing (a signifier) to represent another (the signified) that is not present. Based on the relationship between the signifier and the signified, we can distinguish three kinds of representation:

  • Signals (or Indices): The signifier has a direct, often natural or causal, link to the signified (e.g., smoke signifies fire, crying signifies distress).
  • Symbols: The signifier bears some physical resemblance or analogous relationship to the signified (e.g., a drawing of a house represents a real house, using a block as a phone). This is common in pretend play.
  • Signs (Linguistic): The relationship between the signifier (e.g., a word) and the signified (the concept or object it represents) is arbitrary and based on social convention (e.g., the word ‘dog’ bears no resemblance to the actual animal). Language is the primary system of signs.
