The personality trait of extraversion has been linked to problematic drinking patterns. Researchers have long hypothesized that such associations are attributable to increased alcohol-reward sensitivity among extraverted individuals, and surveys suggest that individuals high in extraversion gain greater mood enhancement from alcohol than those low in extraversion. Surprisingly, however, alcohol...

Neuroticism is the personality dimension most frequently associated with chronic fatigue syndrome (CFS). Most studies have also shown that CFS patients are less extraverted than non-CFS patients, but results have been inconsistent, possibly because the facets of the extraversion dimension have not been separately analyzed. This study has the following aims: to assess the personality profile of ...

The Myers-Briggs Type Indicator (MBTI), a popular personality test, was used to profile the personalities of in-patient alcoholics/substance-use disorder patients who had, and those who did not have, a concurrent affective disorder diagnosis. The MBTI divides individuals into eight categories: Extroverts and Introverts, Sensors and Intuitives, Thinkers and Feelers, and Judgers and Perceivers. A...

Through insights gained from the clinical study of patients, two broad personality types are distinguished'-the introverted and the extraverted. In the introduction to "Psychological Types," the theory is stated; the method to be followed to understand them is described; and, the definition, characteristics and effects of these two personality types are summarized. For the introverted personali...

The current study examined the relation between self-esteem and the Big Five personality dimensions. Data were collected over the Internet from a large heterogeneous sample of individuals who ranged in age from 9 to 90 years (N 5 326,641). Collectively, the Big Five accounted for 34% of the variance in self-esteem. High self-esteem individuals were emotionally stable, extraverted, and conscient...

The perceived beauty of a potential partner has traditionally been explained in terms of physical characteristics such as body weight and the waist-to-hip ratio (WHR), while non-physical characteristics have been neglected. This study looked at the contribution of body weight, WHR and personality to ratings of overall female attractiveness. Seventy-six participants rated 30 line drawings that v...

In this paper we present the results from a survey about the beliefs, practices, and personalities of software engineers in a large software company. The survey received 797 responses. We report statistics about beliefs of software engineers, their work practices, as well as differences in those with respect to personality traits. For example, we observed no personality differences between deve...

BACKGROUND Previous studies have revealed that self-related tasks (items) receive more attention than non-self-related, and that they elicit event-related potential (ERP) components with larger amplitudes. Since personality has been reported as one of the biological correlates influencing these components, as well as our behavioural differences, it is important to examine how it affects our sel...

Heterogeneity in the Production of Human Capital We derive a tractable nonlinear earnings function which we estimate separately for each individual in the NLSY79 data. These estimates yield five important parameters for each individual: three ability measures (two representing the ability to learn and one the ability to earn), a rate of skill depreciation, and a time discount rate. In addition,...
