The opponent-process theory is a model that views two components as being pairs that are opposite to each other, such that if one component is experienced, the other component will be repressed. Therefore, an increase in pain should bring about a decrease in pleasure, and a decrease in pain should bring about an increase in pleasure or pain relief.
Because of the only relatively recent discovery of neurons and how they conduct and interpret signals, including sensations such as pain, within the body, various theories have been proposed as to the causes of pain and its role or function. Even within seemingly limited groups, such as the ancient Greeks, there were competing theories as to ...
Epicurus in the ancient world, and later Jeremy Bentham, laid stress upon the role of pleasure in directing human life, the latter stating: "Nature has placed mankind under the governance of two sovereign masters, pain and pleasure".

A stressor is inherently neutral meaning that the same stressor can ...

[ 10 ] In 1968, three years after the introduction of the gate control theory, Ronald Melzack concluded that pain is a multidimensional complex with numerous sensory, affective, cognitive, and evaluative components.
An example of the possible effects of misattribution of arousal is perceiving a potential partner as more attractive because of a heightened state of physiological stress. A study done by White et al. (1981) [ 2 ] investigated this phenomenon and found that those in an unrelated aroused state will rate an attractive confederate more highly than ...
Stress is the leading cause of mental and physical problems, [citation needed] therefore feeling relaxed is often beneficial for a person's health. When a person is highly stressed, the sympathetic nervous system is activated because one is in a fight-or-flight response mode; over time, this could have negative effects on a human body.
The diathesis-stress model, also known as the vulnerability–stress model, is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and stress caused by life experiences.
