DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an intelligence testing device.
BACKGROUND ART
Recently, in the department of neuropsychiatry, an intelligence testing method has been proposed for knowing the degree of advancement of intelligence or diagnosing aging and dementia.
As for conventional techniques, tests for finding a decrease in the mentation of old people include a Hasegawa type dementia scale and an N-type mentation test. These tests judge whether or not a subject can correctly answer questions concerning orientation and impressibility.
On the other hand, according to what is experienced in picture drawing therapy, pictures drawn by many old people are characterized by loss of freedom and collapse of form. This suggests that a decrease in mentation can be surmised from pictures. However, pictures themselves contain so much information that quantitization is difficult. Therefore, development of a method of judgement was started in about 1987, which method, substituting the act of "marking points" which is the simplest form of drawing pictures, is based on the analysis of distribution or locus of points (references: "ANALYSIS OF POINTS"--PRELIMINARY STUDY, Mikio Hayashi and Toshikazu Hakamada, Kosei-Nenkin Hospital Annual Report Vol. 14 (1987), pp. 283-290; "ANALYSIS OF POINTS"--PRELIMINARY STUDY II, Mikio Hayashi, Makiko Tominaga and Syuniti Hakamada, Kosei-Nenkin Hospital Annual Report Vol. 15 (1988), pp. 317-323; "EARLY DETECTION OF DEMENTIA IN PICTURE THERAPY", Mikio Hayasi and Chitaru Tanaka, in CLINICAL PICTURE STUDY IV (1988), published by Kongo Publishing Co., Ltd., pp. 33-48, "ANALYSIS OF POINTS"--PRELIMINARY STUDY III, Mikio Hayashi and Chitaru Tanaka, Kosei Nenkin Hospital Annual Report Vol. 16 (1989), pp. 323-339). The principle of this "point analysing method" consists of instructing a subject to enter a plurality of points (I points) randomly and distributively in M (vertical).times.N (horizontal) quadratures and specifying the positions of the points by the coordinates of the quadratures in which they are entered.
As a precondition, let the horizontal direction of the quadratures be called the x direction and the vertical direction thereof the y direction. As the numbers adopted since the beginning of the development of the method, the number of columns (the number of quadratures in the x direction) M=12 and the number of rows (the number of quadratures in the y direction) N=20 and the number of entered points I=30. If the i-th entered point (i=1, 2, . . . , 3) is entered in a quadrature which is located at the a.sub.i -th position from the left and b.sub.i -th position from the top, the coordinates of said point are (a.sub.i, b.sub.i). In this case, a.sub.i and b.sub.i are integers which satisfy the relations 1.ltoreq.a.sub.i .ltoreq.12 and 1.ltoreq.b.sub.i .ltoreq.20.
Let {u.sub.i, v.sub.i)} be the progression of difference in the order sequence {(a.sub.i, b.sub.i)} of the coordinates of the 30 points. That is,
In this case, i=1, 2, . . . , 29.
As is clear from this definition, u.sub.i and v.sub.i are integers which satisfy the relations:
(1) First method: dispersion in distribution of points
Let m.sub.k be the number of points i whose x coordinates satisfy the relation a.sub.i =k, that is, which belong to the k-th column, and
let n.sub.t be the number of points i whose y coordinates satisfy the relation b.sub.i =t, that is, which belong to the t-th column.
Then D.sub.x and D.sub.y are found as follows. ##EQU1## Since I/M=5/2 and I/N=3/2 are the total number of marked points divided by the number of columns and by the number of rows, respectively, they are values which should be the average number of marked points in each column and each row in a large number of samples in which the points are marked truly at random. Therefore, D.sub.x and D.sub.y respectively represent the sums of deviations from the average values of the numbers of actually marked points in each column and each row. The coordinates (D.sub.x, D.sub.y) are specified and the lowering in mentation is judged from t
