Traits are each complex part of our personality. Everyone's unique personality is created by specific traits that have either been picked up over time or even genetically given. Factor analysis can measure your traits by identifying-using tests- your person's basic components of intelligence. Your answers get analyzed and extraversion/ emotionality factors will emerge as your basic personality dimensions. Eysenck believed that biological factors- like arousal, hormones, and environment- affect your personality dimension.
Eysenck's personality theory was based on temperaments, which he believed were heavily impacted by genetic factors. He used factor analysis to determine the two fundamental characteristics of personality, which were extraversion, neuroticism, and psychoticism
