EIGHT TEXT FIGURES 
The present paper consists of three parts. Part one gives 
the results of the application of the Otis group intelligence 
scale to 1,000 male and 752 female teachers in Tayabas, Batan- 
gas, Laguna, and Rizal Provinces. Part two gives the results 
of the same scale applied to 166 male and 59 female teachers 
from all parts of the Philippines, gathered in convention at 
Baguio. Part three gives the results of the application of the 
Yerkes point scale to 146 boys and 29 girls, many of them of 
mixed blood, in the Palawan Provincial School at Cuyo. 
PART ONE 
The Otis group intelligence scale was devised by Dr. Arthur 
S. Otis, of Leland Stanford Junior University, and was copy- 
righted by the World Book Company in 1919. It was one of the 
first and most satisfactory scales devised for testing subjects 
in groups, It is very similar in form to the Alpha examination 
adopted by the United States Army later.’ 
The Otis scale tests chiefly the higher mental processes, such 
as controlled association, analysis, logical judgment, synthesis, 
and generalization. Comprehension of language (English), . 
memory, and imagination are, of course, also involved. In- 
cident to the group method, in which the correct response (to 
be underlined by the subject) to each problem is suggested along 
with several incorrect responses—which makes possible a rapid 
scoring of the examination sheets by means of stencils—is the 
important element of recognition, but what Terman says of 
recognition in reading probably applies here: 
Recognition is for the most part an associative process. Rapid and 
accurate association will mean ready recognition of the printed form.’
