Abstract

This study aims at pursuing the change resulted from repeated testing given to the subjects, Junior High School pupils, either by their teacher or nonteacher, Who is an instructor from the outside.The experiments are carried Out in the following four conditions.(1) The first test is given by the teacher and the second one by an instructor from the outside.(2) The first test is given by the instructor from the outside and the second one by the teacher.(3) Both the first and the second tests are given by the teacher.(4) Both the first and the second tests are given by the instructor from the outside.The subjects are the boys and girls of the first grade Junior High School (Table 2) and the test used. is the Honesty test. and the results is considered to be affected neither by the repetition are of the test nor by the influence of memory.Results:The following findings were revealed through this investigation:(1) As the first test carried out by the teacher, small number of subjects committed false behaviors, only whereas a great number of false behaviors occurred in the testing done by the instructor from the outside.(2) However, it has been clear through the second administration of test that the teacher does not always give stronger inhibitory influence upon the subjects than by the instructor from the outside. In the case of the second condition, the amount of false behaviors done by the teacher is bigger than that by the instrcutor from the outside.(3) Thus it seems that the experience of the subjects in the previous test affects the result of the next test to a great extent. However, the amount of the occurrence of false behaviors is small when both the first test and the second test are given by the same person, either the teacher or the instructor from the outside, that is in the case of the third and fourth condition.As to the next step of our research, subjects should be also given other tests and should be analysed in terms of their age. Furthermore, the case in which the instructor from the outside would be more inhibitory towards the subjects than the teacher should be investigated.
