在黑色或白色开阔视野中对50、100和150日龄的48只雄性和48只雌性Holtzman大鼠进行测试，以确定不同视野亮度对排便和排便评分的影响。除50日龄动物外，所有排便评分与排便评分之间均呈显著负相关。在试验期间，所有动物的排便评分均降低;排便评分保持不变。试验没有与年龄，性别或亮度的任何措施。在这两个领域中，女性越过更多的广场比男性在100和150天的年龄，但在50天的年龄在american没有性别差异。最值得注意的是作为场的亮度的函数的性别差异，而男性的分数没有差异，女性走动显着更多，往往排便较少，在白色领域。结果描述的需要标准化的开放领域。
48 male and 48 female Holtzman rats, ages 50, 100, and 150 days, were tested in a black or white open field to determine the effect of varying brightness of the field upon ambulation and defecation scores. There were significant negative correlations between all ambulation and defecation scores, except for the 50-day-old animals. Ambulation scores decreased over trials for all animals; defecation scores remained the same. Trials did not interact with age, sex, or brightness on either measure. In both fields females crossed more squares than males at ages 100 and 150 days, but there were no sex differences in ambulation at age 50 days. Most notable was a sex difference as a function of brightness of field; whereas male scores did not differ, females ambulated significantly more and tended to defecate less in the white field. Results are described in terms of the need for standardization of the open field.
