Content: Chronic stress
Main article: Chronic stress
Chronic stress is the response to emotional pressure suffered for a prolonged period of time in which an individual perceives they have little or no control. When chronic stress is experienced, the body is in a state of continuous physiological arousal. Normally, the body activates a fight-or-flight-response, and when the perceived stress is over the body returns to a state of homeostasis. When chronic stress is perceived, however, the body is in a continuous state of fight-or-flight response and never reaches a state of homeostasis. The physiological effects of chronic stress can negatively affect memory and learning. One study used rats to show the effects of chronic stress on memory by exposing them to a cat for five weeks and being randomly assigned to a different group each day. Their stress was measured in a naturalistic setting by observing their open field behaviour, and the effect on memory was estimated using the radial arm water maze (RAWM). In the RAWM, rats are taught the place of a platform that is placed below the surface of the water. They must recall this later to discover the platform to exit the water.
