How many seconds are allocated for item 1 on the BD assessment?

The correct answer is based on the specific guidelines provided for the Block Design (BD) subtest of the WISC-V. For item 1 on the Block Design task, the allocated time is indeed 30 seconds. During this time, the child is required to replicate a specific design using colored blocks, which assesses both spatial and visual-motor skills. This time limit allows for a manageable assessment of the child's ability to interpret and construct visual patterns without being overly pressured to perform quickly, ensuring a balance between accuracy and efficiency. The timed nature of the task also contributes to evaluating the child's processing speed in a non-verbal context, which plays a significant role in overall cognitive assessment.
