What are the three types of errors that can occur in BD?

The correct answer highlights three specific types of errors that can arise during the Block Design (BD) subtest, a component of the WISC-V. These errors are dimension, gap, and rotation.

The dimension error pertains to the misinterpretation of the spatial relationships or sizes of the blocks relative to the model, which can lead to incorrect construction of the design. Gap errors occur when the participant neglects to account for the spaces between blocks or does not align them properly, which affects the overall accuracy of the design. Finally, rotation errors occur when a block is placed at the wrong angle, resulting in a deviation from the intended design.

Understanding these types of errors is crucial for interpreting the performance on the Block Design subtest, as they indicate specific areas where a child might struggle with visual-spatial reasoning or fine motor skills. This insight is valuable for educators and psychologists in crafting appropriate interventions and support based on individual needs.
