1. Deconstruction of Behavioral Phenomena
Starting around 10-11 months old, babies develop a wild obsession with a destructive game: When mom has just built a beautiful castle with building blocks or neatly arranged shoes on a shoe rack, the baby rushes over at top speed, excitedly waving to completely demolish the castle of blocks or pulling all the shoes to the ground. Many mothers, exhausted as they are, tend to think that the child is deliberately "venting destructive desires" or "disrespecting the labor results".
2. Core Variables Behind the Behavior:
Three-Dimensional Space Deconstruction (Deconstruction Schema) and Efficacy Experiment
In cognitive development science, this "obsession with demolition" behavior is a high-level spatial logical calculation and self-awareness confirmation in the infant brain:
• Experiment on the Deconstruction of Spatial Connectivity: Compared to precisely stacking scattered building blocks (which requires extremely high frontal lobe movement planning ability), demolishing a previously towering solid object to instantly collapse and scatter through "demolition" is the most efficient spatial causal law experiment for babies. They are observing and understanding how solids transform from a "collection" to a "separation" through vision, hearing (the sound of the blocks scattering), and touch.
• Bursting Efficacy (Self-Efficacy) Confirmation: At this point, the baby begins to realize that "I" is an independent object outside the environment. When they realize that a small push of their own can cause such a dramatic deformation and collapse of a huge, rigid object, their brain secretes a large amount of dopamine. This "I can change the world" sense of control is the cornerstone for them to build early self-confidence and willpower.
3. Deep Cognitive Reconstruction
Mother's Perspective Reconstruction: Demolition is not the opposite of construction; demolition itself is a valuable study of space. Children must first learn how to perfectly "deconstruct space" before they can learn to precisely "reconstruct space". For babies at this stage, the mother does not need to be frustrated by the destruction of the painstakingly built structure, nor should she scold. You can actively join this experiment and turn it into an interactive game: You are responsible for building, and at the moment of the baby's demolition, use exaggerated and joyful voices to match the physical collapse (such as imitating the voice of a building collapsing), which can satisfy their dual desires of psychology and cognition. Then guide them to experience the process of collecting scattered objects back to their original positions, allowing them to establish a high-level physical order sense in the process of "aggregation $\rightarrow$ dispersion $\rightarrow$ re-aggregation" of space.
