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 ...
Running or any other form of exercise would also be considered an acute stressor. Some exciting or exhilarating experiences such as riding a roller coaster is an acute stress but is usually very enjoyable. Acute stress is a short term stress and as a result, does not have enough time to do the damage that long term stress causes. [29]
Schematic overview of the classes of stresses in plants Neurohormonal response to stress. Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. [1] When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. [2]
A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. [1] Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.
The stressor, either physically present or recollected, will produce the same effect and trigger a chronic stress response. [1] There is a wide range of chronic stressors, but most entail relatively prolonged problems, conflicts and threats that people encounter on a daily basis. [ 2 ]
Stress has been shown to both improve and impair WM. In a study by Duncko et al., the positive effect of stress manifested itself as a decreased reaction time in participants, while the negative effect of stress causes more false alarms and mistakes when compared to a normal condition. [34]

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]
