Dental hygiene students from Hudson Valley Community College were introduced to the subject of developmental disabilities during their senior year. Each student received three hours of lecture and spent one afternoon in the dental clinic of the O. D. Heck Developmental Center. The Personal Attribute Inventory was administered to the students before and after the program to determine attitudes about mental retardation. A determination was made as to whether the timing of the visit to the center, relative to the presentation of the lectures, made a difference in students' attitudes. No statistically significant difference in attitudes was found between the beginning and the end of the year, and there were no changes in attitudes attributable to the placement of the lectures vis-à-vis the site visit.
哈德逊谷社区学院的口腔卫生专业学生在大四时开始接触发育障碍这一学科。每位学生都接受了三个小时的讲座，并在O.D.赫克发育中心的牙科诊所度过了一个下午。在课程前后，学生们都接受了个人特质量表测试，以确定他们对智力迟钝的态度。研究人员还确定，相对于讲座的安排，前往该中心的时间是否会对学生的态度产生影响。结果发现，年初和年末学生的态度没有统计学上的显著差异，而且讲座安排与实地考察的先后顺序对学生态度也没有影响。
