THORNDIKE'S PROPOSED TESTS FOR THE MEASUREMENT OF INTELLIGENCE OF ADULTS (_Science_, Jan. 24, 1913) Series to consist of eight tests, four trials of each being given. 1. Supplying words to make sense in mutilated passages, the four trials being of four grades of difficulty. (See Trabue's Completion Test for sample of this material.) 2. Giving the "opposites" of words, each trial comprising twenty words, the four trials being of four grades of difficulty. (See Woodworth-Wells: Opposites Tests for sample.) 3. Memorizing a given word in connection with a given form, so as to be able to give the former when the latter is presented, there being 10 pairs in each "trial." (See special blanks.) 4. Selecting from 50 forms a group of 25 of these which have been previously seen and examined for a minute or two. (See special blanks.) 5. Marking the necessarily false statements in mixed series of false and true statements, the four trials being of four grades of difficulty. (See special blanks.) 6. Addition. (See Woodworth-Wells: Addition Tests.) 7. Directions Tests. (See Woodworth-Wells: Hard Directions.) 8. Selecting valid from invalid reasons for a given fact, the four tests being of four grades of difficulty. (See special blank.) MISCELLANEOUS EMPIRICAL TESTS
