The Form Board Ability of Young Deaf and Hearing Children

men. Twenty deaf children, aged seven, and twenty hearing children, aged six, were so tested. Again, in October, 1915, the same children Avere retested. Eighteen of the twenty deaf children were available, while only fourteen of the twenty hearing children could be located. The others had moved to other parts of the city. We have, then, the records for eighteen deaf children and fourteen hearing children on the Seguin Form Board, tested on entering school and again one year later. We also have the records for seventeen deaf children, aged seven, who entered school in September, 1915. The Form Board used was made from the description given by Sylvester,1 but it differs in this respect,?the insets fit in flush with the board proper. Hence, our results are not comparable with either the norms of Goddard2 or of Sylvester.3 We do not maintain that our modification of the form board is better or worse than the standard one in use. It requires a greater degree of muscular co-ordination to perform our test and therefore it is probably testing more factors than the standard board. At any rate the high correlations between performances separated by a year's interval indicate the reliability of the board we used.
