As demonstrated in four experiments, dogs and pups of the Arkansas Line of Nervous Pointers, in contrast to kennel-mate dogs of the normal line, respond to manual inversion and brief restraint in an open sling with prolonged, mainly hypertonic, immobility. This response is consistent and replicable. At least in 4-month-old pups, the duration of sling immobility is positively correlated with the degree of behavioral pathology as determined by the objective Human Interaction Test. We found no evidence of basic difference between upright freezing and supine immobility.
四项实验表明，与正常品系的同窝犬相比，阿肯色神经指示犬品系的犬和幼犬在开放式吊索中对人工翻转和短暂约束的反应是长时间的、主要为高渗性的不动。这种反应是一致且可重复的。至少在4个月大的幼犬中，吊索不动的持续时间与客观的人际互动测试所确定的行为病理学程度呈正相关。我们没有发现直立性僵住和仰卧不动之间存在基本差异的证据。
