In psychology, the Big Five personality traits are five broad domains or dimensions of personality that are used to describe human personality, the five-factor model (FFM). The five factors are openness, conscientiousness, extroversion, agreeableness, and neurotic ism. Acronyms commonly used to refer to the five traits collectively are OCEAN or CANOE. Beneath each global factor, a cluster of correlated and more specific primary factors are found; for example, extroversion includes such related qualities as gregariousness, assertiveness, excitement seeking, warmth, activity, and positive emotions.
The Big Five model is able to account for different traits in personality without overlapping. Empirical research has shown that the Big Five personality traits show consistency in interviews, self-descriptions and observations. Moreover, this five-factor structure seems to be found across a wide range of participants of different ages and of different cultures.
A summary of the factors of the Big Five and their constituent traits, such that they form the acronym OCEAN:
Openness to experience: (inventive/curious vs. consistent/cautious). Appreciation for art, emotion, adventure, unusual ideas, curiosity, and variety of experience. Openness reflects the degree of intellectual curiosity, creativity and a preference for novelty and variety a person has. It is also described as the extent to which a person is imaginative or independent, and depicts a personal preference for a variety of activities over a strict routine. Some disagreement remains about how to interpret the openness factor, which is sometimes called "intellect" rather than openness to experience.
Conscientiousness: (efficient/organized vs. easy-going/careless). A tendency to be organized and dependable, show self-discipline, act dutifully, aim for achievement, and prefer planned rather than spontaneous behavior.
Extroversion: (outgoing/energetic vs. solitary/reserved). Energy, positive emotions, surgency, assertiveness, sociability and the tendency to seek stimulation in the company of others, and talkativeness.
Agreeableness: (friendly/compassionate vs. analytical/detached). A tendency to be compassionate and cooperative rather than suspicious and antagonistic towards others. It is also a measure of one's trusting and helpful nature, and whether a person is generally well tempered or not.
Neurotic ism: (sensitive/nervous vs. secure/confident). The tendency to experience unpleasant emotions easily, such as anger, anxiety, depression, and vulnerability. Neuroticism also refers to the degree of emotional stability and impulse control and is sometimes referred to by its low pole, "emotional stability".
