For FW, how many seconds are allowed for items 1-18?

The correct answer is that for items 1-18, 20 seconds are allowed for each item. This specific time limit is established to ensure that children can demonstrate their cognitive abilities without feeling rushed. A standardized time limit helps maintain the consistency of the test and also aids in accurately measuring a child's verbal comprehension and processing speed.

By allowing 20 seconds per item, it provides a fair amount of time for the child to process the information and formulate a response, which is crucial for obtaining valid results in assessing their cognitive skills. Such time limits are designed to evaluate the child's performance under typical testing conditions, contributing to the overall reliability of the WISC-V. This structure supports the test's objective in assessing various domains of intellectual functioning in children.
