What should an examiner say if a child makes a rotation error on the block design subtest?

When a child makes a rotation error on the block design subtest, the examiner should provide guidance that allows the child to correct their mistake and understand the task better. Saying "Turn it the correct way and explain" is appropriate because it offers a direct opportunity for the child to correct their work while simultaneously clarifying any confusion they may have about the task. This response also encourages problem-solving and reinforces learning through understanding spatial relationships, which is a key component of the block design subtest.

Providing this kind of feedback can enhance the child's learning experience, as it not only addresses the current error but also helps develop their ability to visualize and manipulate objects in space. This aspect of constructive feedback is essential in a testing environment that aims to measure a child's cognitive abilities accurately. The other choices do not promote an understanding of the task or assist in improving the child's skills effectively.
