The effects of an institutional tour on college students' attitudes toward the mentally retarded child, mentally retarded adult, state school for mentally retarded persons, and ward attendant at a state school for mentally retarded persons were investigated. Four separate Semantic Differential Scales were administered to 179 subjects prior to being given the alternative of touring a state school for mentally retarded persons (72 subjects took the tour). Pretest responses were used to divide subjects into initially positive or negative attitude groups. Posttest scores for each concept were then analyzed by a two-way classification mixed-models analysis of variance for unequal Ns. Results indicated significant positive effects on attitudes toward mental retardation as a function of the institutional tour.
研究了机构参观对大学生对智障儿童、智障成年人、智障人士州立学校以及智障人士州立学校病房护理员态度的影响。在179名受试者有机会参观智障人士州立学校之前（72名受试者进行了参观），分别对他们进行了四个独立的语义差异量表测试。预测试的回答被用来将受试者分为初始态度积极或消极的组。然后，通过对不等N的双向分类混合模型方差分析，分析了每个概念的后测分数。结果表明，机构参观对智障态度有显著的积极影响。
