Freezing behavior 如何翻譯
Freezing behavior is the fearful reaction to specific stimuli, most commonly observed by animals. It is caused by the sympathetic nervous system to deal with threats. Studies typically assess a conditioned freezing behavior response to stimuli that typically or innately do not cause fear, such as a tone or shock. Freezing behavior is most easily characterized by changes in blood pressure and lengths of time in crouching position, but it also is known to cause changes such as shortness of breath, increased heart rate, sweating, or choking sensation. However, since it is difficult to measure these sympathetic responses to fear stimuli, studies are typically confined to simple crouching times. A response to stimuli typically is said to be a "fight or flight", but can be shown as rather "fright, fight or flight." In addition, freezing is observed to occur before a fight or flight response.
