Extraversion/Introversion 9/24 Extraversion is characterized by being outgoing, talkative, high on positive affect (feeling good), and in need of external stimulation. According to Eysenck’s arousal theory of extraversion, there is an optimal level of cortical arousal, and performance deteriorates as one becomes more or less aroused than this optimal level. Arousal can be measured by skin conductance, brain waves or sweating. At very low and very high levels of arousal, performance is low, but at a better midlevel of arousal, performance is maximized. Extraverts, according to Eysenck’s theory, are chronically under-aroused and bored and are therefore in need of external stimulation to bring them up to an optimal level of performance. About 16 percent of the population tend to fall in this range. Introverts, on the other hand, (also about 16 percent of the population) are chronically overaroused and jittery and are therefore in need of peace and quiet to bring them up to an optimal level of performance. Most people (about 68 percent of the population) fall in the midrange of the extraversion/introversion continuum, an area referred to as ambiversion. Neuroticism/Stability 10/24 Neuroticism or emotionality is characterized by high levels of negative affect such as depression and anxiety. Neuroticism, according to Eysenck’s theory, is based on activation thresholds in the sympathetic nervous system or visceral brain. This is the part of the brain that is responsible for the fight-or-flight response in the face of danger. Activation can be measured by heart rate, blood pressure, cold hands, sweating and muscular tension (especially in the forehead). Neurotic people — who have low activation thresholds, and unable to inhibit or control their emotional reactions, experience negative affect (fight-or-flight) in the face of very minor stressors — are easily nervous or upset. Emotionally stable people — who have high activation thresholds and good emotional control, experience negative affect only in the face of very major stressors — are calm and collected under pressure. Lie 2/9 It measures how socially desirable you are trying to be in your answers. Those who score 5 or more on this scale are probably trying to make themselves look good and are not being totally honest in their responses Eysenck Test Results Extroversion (sociability) |||||||||||| 50% Neuroticism (emotionality) |||||||||||||| 52% Psychoticism (rebelliousness) |||||||||| 33% This test reflects the ideas of Hans Eysenck a pioneer in the field of personality research. Through research and statistical analysis he determined that personality is composed of three main elements: Extroversion, Neuroticism, and Psychoticism. Most current researchers agree on the significance of the first two traits, but there is less consensus on the third (so he may be wrong about it's central importance but it clearly plays some role in personality). Most people will score lower on Psychoticism. While Psychoticism implies more negative qualities than the other two traits (typically), a link has been found is several studies between higher creativity and higher scores on Psychoticism. Here are your results on each dimension: Extroversion results were medium which suggests you are moderately talkative, outgoing, sociable and interacting. Neuroticism results were medium which suggests you are moderately worrying, insecure, emotional, and anxious. Psychoticism results were moderately low which suggests you are, at times, overly kind natured, trusting, and helpful at the expense of your own individual development (martyr complex). Prior to Eysenck's discovery of Psychoticism, he correlated his original two traits (introversion and neuroticism) with an ancient greek personality system known as the Galen types (Melancholic, Choleric, Sanguine, Phlegmatic). Below is a plotting of your introversion and extraversion scores on that map.
