On January, 2, 1922 (aged 7 years 6 months), A was given the _Stenquist Assembling Tests of General Mechanical Ability_ and he made a score of 7 points only. He could tell what mechanisms were to be constructed from the materials in five out of the ten instances, but he was not "handy" enough to put them together. (The test depends very much upon size and strength of hands and upon the degree to which motor coördination is developed. Young children, therefore, of whatever degree of intelligence, are unable to succeed in it). _Musical sensitivity_. On February 22, 1923, Seashore's _Tests of Musical Sensitivity_ yielded results as follows, using the figures for eighth-grade children for comparison, because of A's Mental Age: TEST PERCENTILE (EIGHTH GRADE) PERCENTILE (ADULTS) A A'S FATHER Consonance Below 27th 36th Pitch 91st 81st Intensity 41st 26th Time Below 17th 78th Tonal memory 70th 9th _Design_. On January 2, 1922, the examiner made the following note in reference to A's performance with Milton Bradley color cubes (with which he always asks to play when he comes to the laboratory): The child can construct the most complicated designs with Milton Bradley's color cubes in less than three minutes each, from memory--the design being exposed to vision and studied for one minute. Three colors are involved--red, blue, yellow, and white. TRAITS OF CHARACTER A has not been rated by any scale for traits of character as, for instance, were the children reported by Terman. There are at hand only statements by persons who know A. The parents both say that A has no troublesome traits of character except "a tendency to fail to take his own part in a fight." If a child strikes him, he often does not strike back but simply does nothing. His parents feel that this indicates a lack of "give and take" that is essential to getting along in the world. The parents describe him as "especially honest, truthful, reliable, affectionate, kind, generous, and modest, with strong control of his emotions."
