RESEARCH IN EDUCATION :— 
Dr. N. T. WaLker.—Recent developments in educational research 
(11.0). 
The paper surveys, within the limits of time assigned, some of the results 
of recent scientific research in education. Special attention is given to the 
work of the Scottish Council for Research in Education, and, in particular, 
the results of the Council’s survey of the intelligence of Scottish children 
are discussed. In connection with research on the problem of the reliability 
of examinations, reference is made to a recent Aberdeen experiment. 
Mention is made of investigations into one of the fundamental problems in 
educational theory, namely, the relative importance of nature and nurture 
in individual development. These inquiries include the novel experiment 
conducted by Prof. and Mrs. Kellogg, which consisted in ‘ adopting’ a 
female chimpanzee of seven and a half months and bringing her up along 
with their infant son for a period of nine months.
