The construction of symmetry in children and adults
Abstract:
The development of the concept of symmetry is important to an overall understanding of cognitive development in children and to spatial cognition in particular. Age differences in the construction of the 3 types of symmetry (bilateral, translational, and radial) were investigated in children and adults engaged in block construction. Children 2-4.5 years old produced bilateral symmetry in low frequencies independent of their precise vertical alignment of blocks. Children 4-12 years old and adults produced all 3 types of symmetry. The hypothesis predicting the sequence and frequency of the 3 types of symmetry based on an analysis of spatial complexity was partially supported. Bilateral symmetry was produced at significantly higher frequencies than the other 2 types across all age groups. Children 5-12 years old produced adult levels of bilateral symmetry while children 9-12 years old reached adult levels of construction of translational and radial symmetry.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
