Altercasting is a subgroup to the role theory. Some roles are naturally absorbed into a person's identity, while others are influenced and pressured to arise. The manipulation factor is contributed through altercasting. With altercasting, the manipulations of factors (positive and negative) must be present for certain roles to occur.
Front suspension of a race car — the caster angle is formed by the line between upper and lower ball joint An example of a chopper with a raked fork at an extreme caster angle. The caster angle [1] or castor angle [2] is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle ...
The concept of Environmental Sensitivity integrates multiple theories on how people respond to negative and positive experiences. These include the frameworks of Diathesis-stress model [4] and Vantage Sensitivity, [5] as well as the three leading theories on more general sensitivity: Differential Susceptibility, [6] [7] Biological Sensitivity to Context, [8] and Sensory processing sensitivity ...
The biopsychological theory of personality is a model of the general biological processes relevant for human psychology, behavior, and personality. The model, proposed by research psychologist Jeffrey Alan Gray in 1970, is well-supported by subsequent research and has general acceptance among professionals.
The negativity bias, [1] also known as the negativity effect, is a cognitive bias that, even when positive or neutral things of equal intensity occur, things of a more negative nature (e.g. unpleasant thoughts, emotions, or social interactions; harmful/traumatic events) have a greater effect on one's psychological state and processes than neutral or positive things.
Evolutionary psychologists consider Charles Darwin's theory of natural selection to be important to an understanding of psychology. [1] Natural selection occurs because individual organisms who are genetically better suited to the current environment leave more descendants, and their genes spread through the population, thus explaining why organisms fit their environments so closely.

This signaling network illustrates the simultaneous positive and negative feedback loops whose exquisite sensitivity helps create a bistable switch. Bistability can only arise in biological and chemical systems if three necessary conditions are fulfilled: positive feedback , a mechanism to filter out small stimuli and a mechanism to prevent ...
Biological applications of bifurcation theory provide a framework for understanding the behavior of biological networks modeled as dynamical systems. In the context of a biological system, bifurcation theory describes how small changes in an input parameter can cause a bifurcation or qualitative change in the behavior of the system.
