Behavioral ecological theories postulate that threatening environments should increase eating speed and vigilance during feeding. In the present experiment, eating speed and scanning behavior during eating were measured in 36 rats in 5 consecutive test sessions under stressful noise (95 dB white noise, n = 18) and control conditions (60 dB, n = 18) after the animals had been habituated to the test environment. Intense noise induced an increase of scanning rate and eating speed. These effects are similar to those reported for novel and light environments.
行为生态学理论假定，威胁性环境会在进食时提高进食速度并增强警觉性。在本实验中，在动物适应测试环境后，于5个连续测试环节中对36只大鼠在应激噪声（95分贝白噪声，n = 18）和对照条件（60分贝，n = 18）下的进食速度和进食时的扫视行为进行了测量。强烈噪声导致扫视率和进食速度增加。这些效应与在新奇和明亮环境中所报道的效应相似。
