What is the number of target symbols present on Form B of Symbol Search?

Form B of the Symbol Search subtest in the WISC-V is designed to assess processing speed and visual-motor coordination. In this specific form, there are two target symbols that children are required to identify from a set of symbols. This design allows for the evaluation of a child's ability to quickly and accurately scan visual information and make decisions under time constraints.

The presence of two target symbols is integral to the design of the test, as it increases the complexity of the task while still allowing for manageable processing demands suited for the age group being tested. Thus, by having two target symbols, the WISC-V effectively assesses both speed and accuracy, which are crucial components of cognitive functioning in children.
