The Gray and McNaughton (2000) theory draws on a wide range of animal data to hypothesize that the emotions of fear and anxiety are separable. The authors tested their hypothesis in two studies. The first study examined associations between scores on questionnaire measures of fear, anxiety, and neuroticism; correlational analysis revealed that fear and anxiety are not interchangeable constructs. The second study examined associations between scores on questionnaire measures of fear/anxiety and performance in a military training setting; regression analysis revealed that fear captured significant variance in performance that was not shared with anxiety. These results imply that hypotheses derived from nonhuman animal data may hold important implications for understanding human emotion and motivation, especially in relation to fear and anxiety.
格雷和麦克诺顿（2000）的理论借鉴了大量动物数据，假设恐惧和焦虑情绪是可分离的。作者在两项研究中检验了他们的假设。第一项研究考察了恐惧、焦虑和神经质问卷测量得分之间的关联；相关分析表明，恐惧和焦虑不是可互换的概念。第二项研究考察了恐惧/焦虑问卷测量得分与军事训练环境中表现之间的关联；回归分析表明，恐惧在表现中捕捉到了与焦虑不共有的显著方差。这些结果意味着，从非人类动物数据得出的假设可能对理解人类情绪和动机具有重要意义，尤其是在恐惧和焦虑方面。
