Narcissism, psychopathy are traits with implications for behaviour in normal populations. Development of questionnaires guided by clinical descriptions. One major question is whether traits explain (cause) behaviour or describe behaviour. Hans eysenck"s pen model: focuses on understanding causes of differences in how people act/think/feel. This model proposes that certain traits are heritable and have a biological foundation. The data comes from self-reports and observer reports. Statistical algorithms determined that five: observed that in almost all major personality theories, two important components: anxiety and extraversion, anxiety and extraversion are observed consistently cross-culturally, reliably appear in factor analyses, quite stable over time. Therefore, there must be something fundamental to these traits: maybe a physiological connections. Note: trait is not simply a physiological response. P,e,n should be assessed in terms of behaviour differences, not just adjective.
