Three hundred million years ago proto-mammals individually competed for resources such as food, territory, and sexual partners.Over time, some species began to live in groups, which brought the evolutionary advantages of increased protection from predators and adversaries, increased access to resources, and better reproductive success.

The goal of the therapy is for the individual to learn how to cope with and overcome their fear in each level of an exposure hierarchy. The process of systematic desensitization occurs in three steps. The first step is to identify the hierarchy of fears. The second step is to learn relaxation or coping techniques.
In fear conditioning, the main circuits that are involved are the sensory areas that process the conditioned and unconditioned stimuli, certain regions of the amygdala that undergo plasticity (or long-term potentiation) during learning, and the regions that bear an effect on the expression of specific conditioned responses. These pathways ...
The least anxiety-provoking situations are ordered at the bottom of the hierarchy while the most anxiety-provoking situations are at the top. Exposure hierarchies typically consist of 10-15 items and will guide the client’s exposure practices. [1] An abbreviated example of an exposure hierarchy is pictured in Image 1.
Self-preservation urges animals to collect energy and resources required to prolong life as well as resources that increase chances of survival. Basic needs are available to most humans (roughly 7 out of 8 people), [11] and usually rather cheaply. The instinct that drives humans to gather resources now drives them to over-consumption or to ...
Food and other necessities were also included within the burial chamber, indicating the potential for a belief system that included life after death. Many human cultures today treat funerals primarily as cultural events, viewed through the lens of morality and language, with little thought given to the utilitarian origins of burying the dead.
Other animals have alternative self-protection methods. Some species of cold-blooded animals change color swiftly to camouflage themselves. [ 49 ] These responses are triggered by the sympathetic nervous system , but, in order to fit the model of fight or flight, the idea of flight must be broadened to include escaping capture either in a ...
Pavlovian fear conditioning is a behavioral paradigm in which organisms learn to predict aversive events. [1] It is a form of learning in which an aversive stimulus (e.g. an electrical shock) is associated with a particular neutral context (e.g., a room) or neutral stimulus (e.g., a tone), resulting in the expression of fear responses to the originally neutral stimulus or context.
