[2] Mason is regarded as an international leader and theoretician in the field of stress research, [ 3 ] where he was one of the field's most prominent ...
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]
A typical allostatic response has been initiated by a stressor and then continues for the duration of the stressor, in which it shuts off as the stressor has ended. Allostatic load is the accumulation of stressors and maladaptive responses that may result in an extreme state, where the stress response does not terminate. [26]
(A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism.) Selye initially (c. 1940s) called this the "general adaptation syndrome" (at the time it was also called "Selye's syndrome"), but he later rebaptized it with the simpler term "stress response".
Hans Selye defined stress as “the nonspecific (that is, common) result of any demand upon the body, be the effect mental or somatic.” [5] This includes the medical definition of stress as a physical demand and the colloquial definition of stress as a psychological demand. A stressor is inherently neutral meaning that the same stressor can ...
