Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations. Reaction time (RT; also referred to as " response time ") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive ...
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass. [ 1]
Training in use of a liferaft – the rule will apply when exposed at sea. In survival, the rule of threes involves the priorities in order to survive. [1] [2] [3] The rule, depending on the place where one lives, may allow people to effectively prepare for emergencies [4] and determine decision-making in case of injury or danger posed by the environment.
Survival of the fittest. Herbert Spencer coined the phrase "survival of the fittest". " Survival of the fittest " [ 1] is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success.
Starvation. Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage [ 1] and eventually, death. The term inanition[ 2] refers to the symptoms and effects of starvation.
The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
The fight-or-flight or the fight-flight-freeze-or-fawn[ 1] (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. [ 2] It was first described by Walter Bradford Cannon in 1915. [ a][ 3] His theory states that animals react to ...
Cat righting reflex. The cat righting reflex is a cat 's innate ability to orient itself as it falls in order to land on its feet. The righting reflex begins to appear at 3–4 weeks of age, and is perfected at 6–9 weeks. [ 1] Cats are able to do this because they have an unusually flexible backbone and no functional clavicle (collarbone).
