Sociometer theory is a theory of self-esteem from an evolutionary psychological perspective which proposes that self-esteem is a gauge (or sociometer) of interpersonal relationships. This theoretical perspective was first introduced by Mark Leary and colleagues in 1995 [ 1 ] [ 2 ] and later expanded on by Kirkpatrick and Ellis. [ 3 ]
The term sociometry relates to its Latin etymology, socius meaning companion, and metrum meaning measure. Jacob Moreno defined sociometry as "the inquiry into the evolution and organization of groups and the position of individuals within them."
The human brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous ...
The extreme male brain theory (EMB), put forward by Baron-Cohen [4] suggests that autistic brains show an exaggeration of the features associated with male brains. These are mainly size and connectivity with males generally having a larger brain with more white matter, leading to increased connectivity in each hemisphere. [4]
Since the brain regions are so specialized in their functioning, damages done to specific areas of the brain can cause specific type of damage. Damage to the left side of the brain can lead to language discrepancies, i.e. difficulty in properly identifying letters, numbers and words, inability to incorporate visual stimuli to comprehend ...
One such region is the nucleus accumbens—a key part of the brain’s reward system that’s fueled by dopamine, a chemical that Wise fondly refers to as “the slutty neurotransmitter” because ...
The fMRI image presents the specific locations where these stages are occurring in the brain while performing this simple mental chronometry task. In the 1980s, neuroimaging experiments allowed researchers to detect the activity in localized brain areas by injecting radionuclides and using positron emission tomography (PET) to detect them. Also ...
The globus pallidus is a structure in the brain involved in the regulation of voluntary movement. [8] It is part of the basal ganglia, which, among many other functions, regulate movements that occur on the subconscious level. The globus pallidus has a predominantly inhibitory effect on movement regulation, balancing cerebellar excitation.
