06+Neuroticism

=Neuroticism= On the opposite end of the spectrum, individuals who score low in neuroticism are more emotionally stable and less reactive to stress. They tend to be calm, even tempered, and less likely to feel tense or rattled. Although they are low in negative emotion, they are not necessarily high on positive emotion. That is an element of the independent trait of [|extraversion]. Neurotic extraverts, for example, would experience high levels of both positive and negative emotional states, a kind of "emotional roller coaster". Individuals who score low on neuroticism (particularly those who are also high on extraversion) generally report more happiness and satisfaction with their lives. Neurotic anxiety occurs when unwanted impulses overwhelm the egos defences and try to come into action.[|[][|6] Neuroticism appears to be related to physiological differences in the brain. [|Hans Eysenck] theorized that neuroticism is a function of activity in the [|limbic system], and his research suggests that people who score highly on measures of neuroticism have a more reactive [|sympathetic nervous system], and are more sensitive to environmental stimulation.[|[][|11][|]] [|Behavioral genetics] researchers have found that a significant portion of the variability on measures of neuroticism can be attributed to genetic factors.[|[][|12][|]] A study with [|positron emission tomography] has found that healthy subjects that score high on the NEO PI-R neuroticism dimension tend to have high [|altanserin] binding in the frontolimbic region of the brain — an indication that these subjects tend to have more of the [|5-HT2A receptor] in that location.[|[][|13][|]] Another study has found that healthy subjects with a high neuroticism score tend to have higher [|DASB] binding in the [|thalamus]; DASB is a [|ligand] that binds to the [|serotonin transporter] protein.[|[][|14][|]] Another [|neuroimaging] study using [|magnetic resonance imaging] to measure brain volume found that the brain volume was negatively correlated to NEO PI-R neuroticism when correcting for possible effects of intracranial volume, sex, and age.[|[][|15][|]] Other studies have associated neuroticism with genetic variations, e.g., with [|5-HTTLPR] — a [|polymorphism] in the [|serotonin transporter] gene.[|[][|16][|]] However, not all studies find such an association.[|[][|17][|]] A [|genome-wide association study] (GWA study) has associated [|single-nucleotide polymorphisms] in the //[|MDGA2]// gene with neuroticism,[|[][|18][|]] however the [|effect sizes] were small. Another GWA study gave some evidence that the rs362584 polymorphism in the //[|SNAP25]// gene was associated with neuroticism.[|[][|19][|]] A 2009 study has found that higher neuroticism is associated with higher decreased brain size with increasing age.[|[][|20][| ]] [|Wikipedia]
 * Neuroticism** is a fundamental personality [|trait] in the study of [|psychology]. It is an enduring tendency to experience negative emotional states. Individuals who score high on neuroticism are more likely than the average to experience such feelings as [|anxiety], [|anger], [|guilt], and [|depressed mood].[|[][|1][|]] They respond more poorly to environmental [|stress], and are more likely to interpret ordinary situations as threatening, and minor frustrations as hopelessly difficult. They are often [|self-conscious] and [|shy], and they may have trouble controlling urges and delaying [|gratification]. Neuroticism is associated with low [|emotional intelligence], which involves emotional regulation, motivation, and [|interpersonal skills].[|[][|2][|]] It is also a risk factor for "[|internalizing]" mental disorders such as phobia, depression, panic disorder, and other anxiety disorders (traditionally called [|neuroses]).[|[][|3][|]][|[][|4][|]][|[][|5][|]]
