Which materials are required for the PS administration?

The correct choice includes the manual, record form, stimulus book 2, and a stopwatch, which are all essential for the proper administration of the Processing Speed (PS) subtests of the WISC-V.

The manual provides detailed instructions on how to administer the test, including guidelines for standardization, scoring, and interpreting results. The record form is crucial for documenting the child's performance during the assessment, allowing for an organized way to present and evaluate responses. The stimulus book 2 contains the specific materials and items needed to conduct the subtests, ensuring that the child engages with the correct content. Lastly, a stopwatch is necessary to time tasks accurately, which is vital for measuring processing speed effectively, as this aspect is a key component of the assessment.

Having all these materials ensures that the test is administered consistently and produces reliable results, which are critical for an accurate assessment of a child's cognitive abilities.
