TEST 2—CUBE ANALYSIS “This is Test 2 _here_. Look.” After everyone has found the page—“Now watch.” The order of procedure is as follows: (1) E. points to the three-cube model on the blackboard, making a rotary movement of the pointer to embrace the entire picture. (2) With similar motions he points to the three-cube model on shelf. (3) E. points next to picture on blackboard and asks, “How many?” (4) E. turns to cube model and counts aloud, putting up his fingers while so doing, and encouraging the men to count with him. (5) E. taps each cube on the blackboard and motions to demonstrator, asking him “How many?” [Illustration: Test 2] (6) Demonstrator (pointing) counts cubes on blackboard silently and writes the figure 3 in proper place. In the second sample of this test, when E. counts cubes of model he (1) counts the three exposed cubes; (2) touches the unexposed cube with pointer; and (3) without removing pointer turns model, so that hidden cube comes into view of group. In other respects procedure with second and third samples is the same as with first. In counting the 12–cube model, E. (1) counts the top row of cubes in the model (left to right), (2) counts the exposed bottom row (right to left), (3) taps with pointer the end cube of hidden row, (4) turns the entire model around and completes his counting. E. then holds model in same place as drawing and counts (in the same order as above) the cubes on blackboard, counting lines between front and top row as representing the hidden row. He then asks demonstrator “How many?” Demonstrator counts the cubes on blackboard (pointing but not speaking) and writes the response. Throughout the demonstration the counting is done deliberately, not more rapidly than one cube per second. At end of demonstration E. points to page and says, “All right. Go ahead.” At the end of 2½ minutes he says, “Stop! Look at me and don’t turn the page.” TEST 3—X-O SERIES “This is Test 3 _here_. Look.” After everyone has found the page—“Now watch.” E. first points to the blank rectangles at the end, then traces each “O” in chart, then traces outline of “O’s” in remaining spaces. Demonstrator, at a gesture, draws them in. E. then traces first “X” in next sample, moves to next “X” by tracing the arc of an imaginary semicircle joining the two, and in the same manner traces each “X,” moving over an arc to the next. He then traces outlines of “X’s” in the proper blank spaces, moving over the imaginary arc in each case, and motions to demonstrator to draw them in. Demonstrator, at a gesture, fills in remaining problems very slowly, standing well to the right of the blackboard and writing with his left hand. E. points to page and says, “All right! Go ahead. Hurry up!” At end of 1¾ minutes he says, “Stop! Turn over the page to Test 4.” [Illustration: Test 3] TEST 4—DIGIT—SYMBOL
