本文报道了实验室饲养的刺鼠（Acomys cahirinus）进入一个大型的、新颖的竞技场时所表现出的探索行为模式的调查。目的是测试我们以前对这个物种的研究所提出的假设。以前的实验中，Acomys的探索行为与小鼠进行了比较，表明每个物种都有一个独特的模式出现和探索。本实验解决的问题，是否可以预测的探索模式Acomys的出现模式所建议的早期实验。数据表明，Acomys在一个大的，新的竞技场的探索行为是合理的可预测的。提供的数据包括动物对新环境中不同刺激的反应，包括新的、明显的物体、食物来源和动物可以返回的笼子。此外，当动物第一次进入竞技场时，记录了与动物行为相关的通过环境不同区域的运动模式。数据表明，有两种类型的策略，或模式，Acomys开始探索一个新的环境。第一种类型包括进入竞技场的延迟出现，随后进入紧邻饲养笼的区域的短暂游览，穿插有较长时间的返回饲养笼。第二种是立即出现，然后在竞技场周围迅速“冲刺”。这两种策略中的哪一种似乎取决于动物在最初接触时的行为。随后的两个实验进一步考虑了这些策略。实验2表明，I型是男性和II型女性的特征，虽然没有差异，女性发情周期。在实验3中，探索模式超过四个连续的测试进行了研究。结果发现，一个人所采取的策略很可能是一致的跨测试。
The present paper reports an investigation of patterns of exploratory behavior shown by laboratory-bred Spiny Mice (Acomys cahirinus) when given access to a large, novel arena. The aim was to test hypotheses suggested by our previous work with this species. Previous experiments in which the exploratory behavior of Acomys was compared with that of Mus had suggested that each species had a characteristic pattern of emergence and exploration. The present experiment addressed the question of whether the exploratory patterns of Acomys could be predicted from patterns of emergence as suggested by earlier experiments. Data are presented which indicate that the exploratory behavior of Acomys in a large, novel arena is reasonably predictable. The data presented include measures of the animal''s responses to different stimuli within the novel environment, including novel, conspicuous objects, food sources, and the holding cage to which the animal could return. In addition, the patterns of movement through different areas of the environment were recorded in relation to the behavior of the animal when it was first given access to the arena. The data indicate that there are two types of strategy, or patterns, by which Acomys begin to explore a novel environment. The first type consists of a delayed emergence into the arena, followed by brief excursions into the area immediately adjacent to the holding cage, interspersed with longer periods of returns to the holding cage. The second type involves immediate emergence, followed by rapid "dashes" around the periphery of the arena. Which of the two strategies is adopted appears to depend upon the animal''s behavior at the time of initial access. Two subsequent experiments considered these strategies further. Experiment 2 indicated that Type I was more characteristic of males and Type II more characteristic of females, although there were no differences related to the female estrous cycle. In Experiment 3, the patterns of exploration over four consecutive tests were investigated. It was found that the strategy adopted by an individual is likely to be consistent across tests.
