Answer to Question 1
Answer: Generally the phrase Big Five refers to concepts derived lexically. They are descriptive in nature and derived from words used in the lexicon of a give group or culture. Both models derive very similar factors with only the names of the factors being different; for example. what the Big Five labels Emotional Stability the FFM calls Neuroticism. The main difference is that while the Big Five is descriptive without any real attempt to explain where the factors come from the FFM sees the five factors as biological traits and is interested in the link between cause and effect. The traits are seen as reflections of causal entities that are genetic or biological in nature.
