What do the items 10-13 in BD scoring relate to?

Items 10-13 in the Block Design (BD) section of the WISC-V scoring specifically relate to the time bonus. The time bonus is a scoring mechanism that acknowledges how quickly a child can correctly reproduce a block design. The faster the completion of the task, the greater the potential for additional points, encouraging not only accuracy but also efficiency in problem-solving. This aspect is significant as it reflects the child's overall cognitive processing speed alongside their visual-spatial abilities and constructive skills.

The inclusion of a time bonus rewards children who can balance speed and accuracy, thus providing a more comprehensive assessment of their capabilities.
