The dominance behavioral system (DBS) can be conceptualized as a biologically-based system which guides dominance motivation, dominant and subordinate behavior, and responsivity to perceptions of power and subordination.
Sep 14, 2024 · Dominant individuals often excel at reading social cues and anticipating others’ reactions. They’re typically quick thinkers, able to respond decisively in high-pressure situations. Hormones and neurotransmitters play a significant role in dominant behavior.

The human brain is split into two hemispheres, right and left. They are both joined together by the corpus callosum, a bundle of nerve fibers which is located in the middle of the brain. The brain contains cortices such as the visual, motor, and somatosensory cortices. These cortices are all contralateral, meaning that each hemisphere controls the ...
Hemispheric lateralization is the idea that both hemispheres are functionally different and that certain mental processes and behaviors are mainly controlled by one hemisphere rather than the other. There is evidence of some specialization of function, mainly regarding differences in language ability. Beyond that, however, the differences that have...
Split-Brains
The brain’s two hemispheres are joined together by the corpus callosum, a thick bundle of millions of nerve fibers. As an outdated treatment for severe epilepsy, the corpus callosum was sliced, meaning the connections between the two hemispheres were halted. People who undergo this procedure are known as split-brain patients. In the 1960’s neurobiologist Roger Sperry conducted experiments on these split-brain patients to test whether there was a localization of function in the hemispheres. Sp...
Language Lateralization
Although it is known that the lateralization of language functions is in the left hemisphere in the majority of people, this lateralization may be dependent on personal handedness. Szaflarski et al. (2002) used functional magnetic resonance imaging (fMRI) on individuals who were left-hand dominant while they completed language acquisition and non-linguistic tasks. It was found through the fMRI that there was more activation in the right hemisphere of the participants, concluding that they had...
Emotion lateralization
A review of the literature investigating the lateralization of emotion in the brain found that the left and right hemispheres have different functions regarding emotions (Silberman & Weingartner, 1986). It was suggested that the right hemisphere is better at controlling emotional expressions and recognizing emotions and is associated with feelings of negative emotions. Whereas the left hemisphere was specialized in dealing with positive emotions. This implied that different functions of emoti...

DISC theory is a model used to describe human behavior, based on four personality traits: Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C). This theory was developed by Dr. William Marston, a psychologist who believed that people have unique, observable ways of thinking, feeling, and behaving.

Dominance is the aspect of social hierarchy that arises from agonistic interactions involving actual aggression or threats and intimidation. Accumulating evidence points to its importance in humans and its separation from prestige--an alternate mechanism in which status arises from competence or benefit-generation ability.
