The effects of crowding and estrus cycling upon visual observing behavior and general activity level in the albino rat were investigated. Experimental groups were composed of non-estrus or estrus females and were subjected to one of three different crowding conditions. Measures of the frequency and duration of observing of photographic slides were taken as well as a measure of general activity. Slides were composed of either geometric patterns or color photographs depicting rats in various social postures. Contrary to previous reports, observing measures did not vary with levels of crowding or stage of estrus. There were, however, differences among the various crowded conditions on a measure of general activity. Relatively short-term crowding was shown to affect estrus based cyclical variation in activity and observing.
研究了拥挤和发情周期对白化大鼠视觉观察行为和一般活动水平的影响。实验组由处于非发情期或发情期的雌性大鼠组成，并接受三种不同拥挤条件之一。记录观察幻灯片的频率和持续时间以及一般活动的测量值。幻灯片由几何图案或描绘大鼠各种社会姿势的彩色照片组成。与先前的报告相反，观察指标并未随拥挤程度或发情阶段而变化。然而，在一般活动的测量方面，不同拥挤条件之间存在差异。结果表明，相对短期的拥挤会影响基于发情的活动和观察的周期性变化。
