RECENT PSYCHOLOGICAL RESEARCH

Our program has been : 
1. To determine experimentally what kinds of stimuli, asso- 
ciations, and reactions are most natural and basic, thus leading 
to the measurement of inherent rather than acquired abilities. 
2. To secure a simple and practical device which can be trans- 
ported, set up, and operated without difficulty, 
3. To control as far as possible every variable in the procedure, 
objective and subjective. 
4. To measure the performance in this test of certain homo- 
geneous, representative groups of persons. 
5. To correlate the results obtained with achievement in the 
particular vocational or industrial pursuits involved by means of 
practical criteria. 
Suitable apparatus having been devised and the test standard- 
ized, we have investigated its value for (1) indicating general 
motor capacity by a comparison of scores of 158 university soph- 
omores in this test and in seven other motor tests; (2) predicting 
the probable competence or incompetence of beginners in tele- 
graphy by testing 173 men in the Army Vocational School at this 
University; (3) the analysis of native capacity of ninety music 
students for musical action; (4) the prediction of skill in type- 
writing based on about 280 cases from various commercial courses. 
THE MEASUREMENT OF MOTILITY IN CHILDREN 
LILLIAN TOW 
What we expect and demand in discipline and performance 
at each age should depend upon a child’s development, mental, 
physical, and functional. 
In this laboratory the evaluation for scientific and diagnostic 
purposes of motor rather than mental capacities is being stressed. 
The object of this investigation is to find what the motor equip- 
ment of children is on entering school. The discovery of the 
basic motor tests which applied at five and six years of age will 
give results which are reliable and significant in that they throw 
light on motor ability. Previous investigations on young children 
have had for their fundamental purpose the comparison of 
mental and motor traits. The aim of this study is to investigate 
the responses of as many different sets of muscles as possible 
and to compare these responses one with another to see if the 
nature of one is an index to a corresponding nature in another.
