Spatial visualization is the ability to mentally manipulate and visualize three-dimensional objects and shapes. It involves understanding how objects are oriented in space and being able to rotate and manipulate them mentally. This skill is important in many fields, including mathematics, engineering, and architecture, as it allows individuals to solve complex problems and understand spatial relationships. Research in spatial visualization focuses on understanding how individuals develop this skill, as well as how it can be improved through training and practice. This area of research is important for understanding human cognition and developing effective educational techniques for teaching spatial skills.
