A typical example of the stress response is a grazing zebra. If the zebra sees a lion closing in for the kill, the stress response is activated as a means to escape its predator. The escape requires intense muscular effort, supported by all of the body's systems. The sympathetic nervous system's activation provides for these needs. A similar ...
A study about stress effects on female songbird’s response to sexual signal for mating indicated that the response to this specific signal can be impaired if the female is exposed to developmental stress. Behavioural changes as a result from developmental stress impairs neural responses to sexual signals, which reduces mating. [5]
For example, students who are taking exams show weaker immune responses if they also report stress due to daily hassles. [45] While responses to acute stressors typically do not impose a health burden on young, healthy individuals, chronic stress in older or unhealthy individuals may have long-term effects that are detrimental to health.

Freezing behavior, also called the freeze response or being petrified, is a reaction to specific stimuli, most commonly observed in prey animals, including humans. [1] [2] When a prey animal has been caught and completely overcome by the predator, it may respond by "freezing up/petrification" or in other words by uncontrollably becoming rigid or limp.
In evolutionary psychology, tend-and-befriend is theorized as having evolved as the typical female response to stress. The tend-and-befriend theoretical model was originally developed by Shelley E. Taylor and her research team at the University of California, Los Angeles and first described in a Psychological Review article published in the ...
For example, research has shown that children with a higher physiological response to stress (indicated by the hormone cortisol) are more strongly affected by their family's financial situation. [14] More specifically, a high cortisol response in children was associated with more positive cognitive development when family income was high, but ...
