WHITE AND COLORED CHILDREN
77
The mental age of the child is determined by the highest group of tests he can pass successfully. Only one failure is permitted in each group. If in addition to passing his group successfully the child passes as many as five tests in higher groups he is given an additional year's credit. Thus, if a seven-year-old child pass all or all but one of the seven-year tests and three of the eight and two of the nine-year tests he is rated eight years mentally. Or if he misses two tests in his group, and therefore fails, but passes five tests in higher groups he is rated as normal. If he is more than three years backward he is mentally defective. The tests begin with the group corresponding to the child's physical age, e. g., a child eight years old is tested first with the eight year old tests, and then with the seven or nine, as the case may require.
The results of the investigation upon the white and colored children may be briefly summarized as follows:
Colored, Percent. |
White, Per Cent. | |||
More than one year backward | 29.4 | 10.2 | ||
Satisfactory | 69.8 | 84.4 | ||
More than one year advanced | 0.8 | 5.3 | ||
The number of white children testing at age is decidedly larger than any other group, whereas for the colored children the largest group is the one testing one year below age. In the satisfactory group there is a difference of nearly 15 per cent, between the white and colored; nearly three times as many colored are more than a year backward, and less than 1 per cent, are more than a year advanced.
The picture tests gave the colored children considerable trouble, probably due to difference in racial esthetics. The tests relating to time and money, distinguishing between morning and afternoon, enumerating the months, counting stamps and making change, the drawing tests, both copying and reproducing from memory were all too difficult. The answers to the questions of comprehension, to the absurd statements and to the problems of various facts, were often absurd or senseless; the best replies, however, compare very favorably with those
