• TRUE - Environmental, social and situational factors can influence these traits, but the influence is minimal.
• TRUE - External influences can amplify the effects of some traits, but the traits themselves remain stable over time.

• 2. Extraversion – Introversion (E)

• Psychoticism (P) - Includes a disposition toward psychosis and a degree of sociopathy.
