One of the most robust observations in personality and emotion research is the finding that extraverts are happier than introverts. Some theorists have attributed this to differential reactivity of the brain reward system, which is central to many biologically inspired models of extraversion. This affective-reactivity hypothesis, which suggests that extraverts should be more susceptible to the ...

Passive avoidance learning occupies a central role in accounts of disinhibited behavior, ranging from psychopaths' persistent criminality (Hare 1970) to extraverts' gregariousness (Gray, 1972). To explore the mechanism underlying passive avoidance deficits, we assessed the relation of extraversion, neuroticism, and response latency after punishment to passive avoidance learning by using two suc...

The personality dimension of introversion/extraversion is one of the few personality dimensions that can be reliably identified from study to study and investigator to investigator. The importance of this demension within personality theory is due both to the stability of the trait and the influential theory of H. J. Eysenck. The basic assumption in Eysenck's theory of introversion/extraversion...

Extraverted children are hypothesized to be most at risk for over-serving and overeating due to environmental cues--such as the size of dinnerware. A within-subject field study of elementary school students found that extraverted children served themselves 33.1% more cereal in larger bowls (16-oz) than in smaller (12-oz) bowls, whereas introverted children were unaffected by bowl size (+5.6%, n...

We conducted three experiments to examine the relationships between emotions and subcomponents of performance. Experiment 1 revealed that anger was associated with enhanced gross muscular peak force performance but that happiness did not influence grammatical reasoning performance. Following Lazarus (1991, 2000a), we examined hope rather than happiness in Experiment 2. As hypothesized, hope yie...

The purpose of the study is to examine how students manifest social presence in IT-supported teaching methods. Specifically, the research examined how students’ psychological type, as measured by the Myers-Briggs Type Indicator, affects their perception of social presence in a specific IT-supported teaching method. Findings revealed that extraverts felt a higher perception of social presence th...

introduction: evaluation of the cerebrospinal fluid (csf) white blood cell (wbc) count and glucose and protein concentrations is used to assess the probability of the presence of central nervous system (cns) infection. although normal values are well established for csf cell counts and protein and glucose contents in children and adults, this is not the case for neonates. the purpose of this st...
