The concept of "right-brained" or "left-brained" individuals is considered a widespread myth which oversimplifies the true nature of the brain's cerebral hemispheres (for a recent counter position, though, see below). Proof leading to the "mythbuster" of the left-/right-brained concept is increasing as more and more studies are brought to light.
[n 10] The right middle temporal gyrus, right brainstem, left hippocampus, right cerebellum, right fuisform gyrus, and left lingual gyrus were also activated during fearful stimuli. Activation of multiple brain regions both indicates that emotions are processed in many parts of the brain and that emotions are complex.
The theory posits that the human mind once operated in a state in which cognitive functions were divided between one part of the brain that appears to be "speaking" and a second part that listens and obeys—a bicameral mind—and that the breakdown of this division gave rise to consciousness in humans.
Attribution (psychology) – Process by which individuals explain causes of behavior and events; Black swan theory – Theory of response to surprise events; Chronostasis – Distortion in the perception of time; Cognitive distortion – Exaggerated or irrational thought pattern; Defence mechanism – Unconscious psychological mechanism
A positive relationship between the size of the amygdala and right-wing political views was found but at approximately a third of the effect size of the original study (r = 0.068 vs r = 0.23). The study also did not find a replication of the original finding of a positive relationship between a larger volume of grey matter in the anterior ...
In her book, Personality Type: An Owners Manual, Thomson advances the hypothesis of a modular relationship between the cognitive functions paralleling left-right brain lateralization. In this approach, the judging functions are in the front-left and back-right brains, and the perception functions are in the back-left and front-right brains.
People may rely on strict routines, a desire for perfection, or a strong need for order to maintain a sense of control and avoid facing uncertainty or undesirable impulses. These defences, such as isolation of affects, intellectualization , and undoing , provide a short-term solution but can result in the development of obsessive-compulsive ...
Rightward asymmetry can be seen in the right central sulcus (potentially suggesting increased connectivity between motor and somatosensory cortices in the left side of the brain), lateral ventricle, entorhinal cortex, amygdala and temporo-parieto-occipital area. Sex-dependent brain asymmetries are also common. For example, human male brains are ...
