For children aged 8-16, which form should be used for the initial items in Symbol Search?

The correct choice emphasizes the use of Form B Demo for the initial items in Symbol Search for children aged 8-16. The Symbol Search subtest is designed to assess processing speed and visual-motor coordination. When administering the WISC-V, it is imperative to follow the standardized procedures, which include using the appropriate demo form to engage with the child effectively.

Form B Demo specifically provides an introductory set of items tailored to the age range of 8-16, ensuring that the difficulty level is appropriate and that the child has a clear understanding of what is expected during the test. This form typically includes examples and practice items that help familiarize children with the test format and tasks before they begin the actual administration. Using the correct demo form enhances the reliability of the assessment, as it sets the stage for an accurate measurement of the child's abilities in this subtest.

In contrast, other forms and options do not align with the requirements for this age group in the Symbol Search subtest. They may not provide the correct introductory context or might not be appropriate for the age range specified, thus potentially leading to confusion or misinterpretation of the test items.
