通过4只雄性和4只雌性老鼠的录像，分析了在半自然环境下的防御行为。在猫暴露前，优势雄猫表现出比从属雄猫更多的攻击性行为、进食、饮水和使用空地。在24小时的时间里，一只猫出现在开阔区域会产生四种防御模式的变化：退缩；不动和运动约束；风险评估;抑制非防御行为。所有Ss在这些模式中都表现出明显和一致的变化，但优势雄性单独表现出与风险评估相关的拐角跑增加。这些结果提供了大鼠在半自然和相对非结构化情况下的防御行为的广泛描述，并表明焦虑过程最初与退缩和行动停止有关，让位于一个关键和持久的风险评估阶段，该阶段提供信息，导致进一步的防御或回归非防御行为。这一分析为研究焦虑提供了新的模式。
Analyzed defensive behaviors in a seminatural setting through videorecordings of groups of 4 male and 4 female rats. Before cat exposure dominant males showed more offensive behavior, eating, drinking, and use of the open area than subordinates. Presentation of a cat in the open area produced changes in four subpatterns of defense over a 24-hr period: withdrawal; immobility and movement constraint; risk assessment; and suppression of nondefensive behaviors. All Ss showed pronounced and consistent changes in each of these patterns, but dominant males alone showed increased risk assessment-related corner runs. These results provide an extensive description of rat defensive behaviors in a seminatural and relatively unstructured situation and suggest that the anxiety process is initially associated with withdrawal and movement arrest, giving way to a crucial and long-lasting risk-assessment stage that provides information leading to either further defensiveness or a return to nondefensive behaviors. This analysis suggests new models for the study of anxiety.
