Using factor analysis, we investigated whether the defensive reactions seen in the elevated T-maze measure different behaviours. Rats were submitted to the elevated T-maze followed by the open-field test. Avoidance 1 and 2 loaded on the same factor, while escape 2 and 3 loaded on a second factor. Baseline avoidance did not load together with locomotor activity in the open-field. These results indicate that the elevated T-maze generates two different defensive behaviours.
通过因子分析，我们研究了高架T迷宫中观察到的防御反应是否衡量了不同的行为。将大鼠置于高架T迷宫中，然后进行旷场试验。回避1和回避2加载在同一因子上，而逃避2和逃避3加载在第二个因子上。旷场试验中的基线回避与运动活动没有共同加载。这些结果表明，高架T迷宫产生了两种不同的防御行为。
