Allostatic load. Allostatic load is "the wear and tear on the body" which accumulates as an individual is exposed to repeated or chronic stress. The term was coined by Bruce McEwen and Eliot Stellar in 1993. It represents the physiological consequences of chronic exposure to fluctuating or heightened neural or neuroendocrine response which ...
Background. The integrated stress response can be triggered within a cell due to either extrinsic or intrinsic conditions. Extrinsic factors include hypoxia, amino acid deprivation, glucose deprivation, viral infection and presence of oxidants. The main intrinsic factor is endoplasmic reticulum stress due to the accumulation of unfolded proteins.
Cognitive appraisal (also called simply 'appraisal') is the subjective interpretation made by an individual to stimuli in the environment. It is a component in a variety of theories relating to stress, mental health, coping, and emotion. It is most notably used in the transactional model of stress and coping, introduced in a 1984 publication by ...
The fight or flight response provided them with the mechanisms to rapidly respond to threats against survival. Examples. 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 ...
In psychology, stress is a feeling of emotional strain and pressure. [1] Stress is a type of psychological pain. Small amounts of stress may be beneficial, as it can improve athletic performance, motivation and reaction to the environment. Excessive amounts of stress, however, can increase the risk of strokes, heart attacks, ulcers, and mental ...
Chronic stress is the physiological or psychological response induced by a long-term internal or external stressor. [1] 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 ...
The threat of negative evaluation is the social stressor. Researchers can measure the stress response by comparing pre-stress salivary cortisol levels and post-stress salivary cortisol levels. Other common stress measures used in the TSST are self-report measures like the State-Trait Anxiety Inventory and physiological measures like heart rate.
(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".
