Developmental Characteristics of Block-Designing Constructive Activities
of Mentally Retarded Children :An Approach from Developmental Neuropsychological
- The purpose of this study is to reveal the general
and individual characteristics of constructive activities
of Mentally Retarded Children. We adopt “Kohs’ Block-
Design Test” in order to analyze their constructive activities.
“Kohs’ Block-Design Test” is well-known as one of
the types of the so-called “performance test” which
measures intelligence.The immediate purpose of this
test is to examine whether the subject is able to construct
the presented design (See Fig.1) with 4 (task-1
to -9)，9 ( task-10 and -11)，or 16 (task-12 to -17)blocks
or not. Each of the blocks has 4 “one-color sides” and 2
“two-color sides” divided on the diagonal.
A. R. Luria and L.S .Tsvetkova( 1964) used this test
to analyze the disturbance of constructive activity in
local brain injuries，and found out the followings;
1) Both of the lesions of the parieto-occipital part of
the brain and of frontal lobes resulted in any disturbance
of constructive activity.
2) But the characteristics of both of the disturbances
were different from each other.
3) Rightly，in order to compensate each of the disturbances
it was necessary to make the different type
of restoration programs.
