<p>Costa and McCrae and the Big Five Factors current consensus - is that there are 5 primary factors of personality.</p><p>The “Big Five” model N E O A C (can spell ocean) was developed to capture the traits that are “most important” in people’s lives.</p><p>Goldstein - credits Galton with first recognizing the importance of the “fundamental lexical hypothesis.”....</p><p>....“The most important individual differences in human transactions will come to be encoded as single terms in some or all of the world’s languages."</p><p>Paul Costa and Robert McCrae - created the NEO-PI-R questionnaire which assess the big five personality traits.</p><p>The NEO-PI-R appears to agree with (be consistent with) both the EPQ (Eysenck) and 16pf (Cattell). Age changes and the NEO-PI-R - Neuroticism and extraversion decrease with age. Agreeableness and conscientiousness increase with age.</p><p>Walter Mischel and the “situationist position” Situationists like Mischel argue that the extent to which traits control behavior is highly exaggerated.... </p><p>....It is “situations” that really control and predict behavior.</p><p>Consistency - the trait situationist debate centers around: 1.cross situational consistency. and 2.longitudinal consistency.</p><p>Personality traits, in general, do tend to be stable across both time and situations.</p>
