Open-field behaviour of individually gentled and non-handled adult Wistar rats in a stressful test situation (loud noise with bright light) was studied. The behaviour on the whole of the two groups differed significantly. While the gentled rats showed mainly signs of stress and explorativity, signs of fear beside stress and, on later trials, explorativity were typical of the non-handled animals. On later trials the behaviour of the non-handled rats neared to that of the gentled ones. In the behaviour of the gentled rats there was but little change as a function of trials. We suggest that individual gentling, beside minimizing fear of human contact, also increases the stability of the rat's reactions.
研究了在应激测试情境（强光与巨响）下，经过个体驯化和未驯化的成年Wistar大鼠的旷场行为。两组大鼠的整体行为存在显著差异。驯化大鼠主要表现出应激和探索迹象，而未驯化动物除应激外还表现出恐惧迹象，在后续试验中则表现出探索性。在后续试验中，未驯化大鼠的行为接近驯化大鼠。驯化大鼠的行为随试验次数变化不大。我们认为，个体驯化除了能减少对人类接触的恐惧外，还能提高大鼠反应的稳定性。
