調査によって得られたデータは,沖縄児童の測定知能に関する吾々の諸仮説を全面的に,あるいは少くとも部分的に支持している。ただ一つの例外は,町の児童と田園児童の差が吾々の予想に反し,比較的に恒常的であるということである｡町の児童と田園児童の差が漸次大きくなるという吾々の予想は,田園児童の知的発達に孤立集団の特徴である age decrement が観察されるだろうという予想に根拠をおくものであったが,この調査の結果から判断すると,沖縄の田園児童(吾々の定義による)には孤立集団的な性格の現れである age decrementが認められないことになる｡
This study was executed in an attempt to test the following hypothses with respect to the developmental changes of measured intelligence of Okinawan school children. (1) The school children in Okinawa would perform below the norms on intelligence tests standardized in Japan proper. The difference between the test norms and test performance of Okinawan school children would beg reater in lower grades than in upper. (2) The intelligence test performance of Okinawan school children would be higher on nonverbal tests than on verbal. The difference between verbal and nonverbal test performances would be greater in lower grades than in upper. (3) The intelligence test performance of rural children would be lower than that of urban children. The difference between urban and rural children would be smaller in lower grades than in upper.
In order to obtain the sample for this study, all elementary schools in Okinawa were clssified according to the general cultural background of each school into town-school and rural-school groups. Four town schools and nine rural schools were selected from each category of schools as their respective samples. Three thausanp and twenty-one children in grades 3 through 6 were drawn from these 13 schools. The town-rural proportion of the sample children was kept constant with thepopulation ratio of the children in the two categories of schools. The combined samples of each grade of the two categories were regarded as the sample for the entire children in corresponding grade of Okinawa. Approximately one half of the children in each grade (third grade excepted) were given the New Tanaka A-Type Intelligence Test which is predominantly verbal, and the other half, the New Tanaka B·Type Intelligence Test which is nonverbal. The third grade children were given only the latter because the former does not apply to them. The data thus collected support the forementioned hypotheses either fully or at least in part. The only exception to this is that the difference between the twon and ruaral samples remains relatively constant rather than becoming gradually larger asexpected. Our hypothesis that the difference between the twon and rural children becomes gradually larger as the grade level advances was based on an assumption that the rural children of Okinawa would show the age decrement lit This paper is based on the writer's MA thesis submitted to the Graduate college of the State University of Iowa in August, 1958. The writer wishes to express his appreciation to Professor James B. Stroud who assisted him in preparing his thesis. which is a characteristic of the intellectual devolopment of children in isolated goups. The findings of this study were discussed from the points of view which comprise the background for our hypothses. They include the bilingualism of a typical Okinawan school children, the rural characteristics of a typical community in Okinawa, and tne isolation of Okinawa, especially in the rural areas, from theoutside.
