![The problem: “picture each word on this sheet in the straight-line alphabet shown on the blackboard [repro- duced below], and write below each word the total number of continuous straight lines (strokes) which would be re- quired to print the word using this style of letter.” Test 3 is believed to be a measure of ability in the men- tal manipulation of quasi-geometrical elements (plane figures—no three dimensional objects). Memory plays very little part (it is believed to be negligible) in the solu- tion of the test problems, as they are made up of very short words. (c) Tests with Strictly Geometrical Elements. Test 4. The Painted Cube Test. Time given: 80 seconds. A three-inch cube, painted on all sides, is cut into one- inch cubes. 1. How many one-inch cubes have paint on three sides? ADSWEP..ki05%. (8). 2. How many one-inch cubes have paint on two sides? PRSWER a. < esis 5 (12). 3. How many one-inch cubes have paint on one side? AMSWET. 055.0% (6). 4. How many one-inch cubes have paint on no side? WOR «ive aba (bE); Test 5. Geometrical Objects Test. Time given: 90 seconds. The problem: “form a mental picture of each object and count the number of straight lines which it would take to construct each one in space.”](https://iiif.wellcomecollection.org/image/b32846782_0055.jp2/full/800%2C/0/default.jpg)
