Answer:
Wechsler created a system for making tests relevant for evaluating adult intelligence
Step-by-step explanation:
Terman, full name: Lewis Madison Terman (1877-1956), was a cognitive psychology professor at Standford University. He is known to develop the Binet test for use in the United States. Although Terman had updated the test quite significantly by making a version that could be used for testing adults, David Welscher(1896-1981) an American psychologist in the 1930s, further expanded the idea and made it increasingly relevant for adults by creating a version that assessed adult intelligence using written tests.
