What is the overarching category for BD scoring items?

The correct choice identifies "Type of errors" as the overarching category for Block Design (BD) scoring items on the WISC-V. In the context of the WISC-V, Block Design tasks require children to recreate designs using colored blocks. As they engage in these tasks, evaluators analyze not only the final product but also the types of errors made during the execution. This includes examining whether the errors are due to spatial reasoning difficulties, lack of problem-solving strategies, or other cognitive factors.

By focusing on the type of errors, psychologists can gain insights into a child's cognitive processing abilities, visual-motor coordination, and understanding of spatial relationships. This information is valuable as it goes beyond merely assigning points for correct designs; it provides a deeper understanding of the child's strengths and weaknesses in visual processing and construction abilities.
