Document Summary
Intercorrelated habits reflect underlying traits in an individual. Intercorrelations between traits are called factors behaviors and habits are based on reward/punishment/environmental experiences, but this learning is based on biological bases of personality because our genetics determine what environments we put ourselves into. Habits are largely a function of experience and learning the acquisition on. Extraversion-introversion: sociability, activity, assertiveness, sensation-seeking, dominance, venturesome-ness, carefree-ness, high scores reflect extraversion and low scores reflect introversion. Neuroticism-stability: not correlated with extraversion-introversion, anxiousness, depression, low self-esteem, shyness, moodiness, tenseness, irrationality, emotionality. Psychoticism-ego control: derived from a prison population, aggressiveness, coldness, egocentricity, impulsivity, antisociality, unempathetic, tough-mindedness, creativity. Extraversion-introversion is based on cortical arousal (electrical activity going on in the brain) Arousal and efficiency graph: optimal level of arousal is moderate, and high and low arousal is below the optimal level of cognitive efficiency. Introverts: faster pupillary constriction and slower dilation to visual stimuli. Extroverts: require lower levels of sedation to reach sedation threshold.
