The diagnoses of several competent medical men are that the girl is a simulator or is an hysterical, and their findings show that she has lied tremendously about her past. (There were never any positive signs of hysteria, and our own opinion is that the case is much better called one of extreme simulation and misrepresentation, as in the diabetes and sputum affairs, etc., and of self-mutilation, as with the hairpin.) We have had ample opportunity to become acquainted with Inez's mental qualities. She has repeatedly been given tests for mental ability. As judged by the average of those seen in our court work we are forced to regard her as having ability clearly above the normal. Her perceptions are keen and quick. She works planfully and rapidly with our concrete problems and shows good powers of mental representation. It is notable that she is very keen to do her best on tests and takes much delight in a good record. Her psychomotor control is astonishingly good. In a certain tapping test, which we consider well done if the individual has succeeded in tapping in 90 squares in 30 seconds, she did 117 and 129 at two successive trials with only one error in each. This is next to the best record we have ever seen. Our puzzle box, which is seldom opened in less than 2 minutes, she planfully attacked and conquered in 52 seconds. She also rapidly put it together again, which is an unusual performance. Reaction times on the antonym test, giving the opposites to words, were very low; average 1.4 seconds. Her immediate memory for words was normal, but nothing extraordinary. She gave correctly, although not quite in logical order, 18 out of 20 items on a passage which she read herself. On a passage read four times to her she gave 11 out of 12 items in correct sequence. The Kent-Rosanoff association test showed, to our surprise, nothing peculiar. Notwithstanding her known social characteristics, there were very few egocentric or subjective reactions. Nor did the ``Aussage'' test show great peculiarity. On free recital she gave 17 items, two of which were incorrect. They were misinterpretations rather than inventions, however. On questioning she added 15 items. She was incorrect on 5 more details, but all of these were denials of objects actually to be seen in the picture. Not one was a fictitious addition. She rejected all the 6 suggestions proffered.
