PSYC 332 Chapter Notes - Chapter 6: Frontal Lobe, Longitudinal Study, Trait Theory
Longitudinal studies show remarkably high differential continuity in personality traits over the adult lifespan: conley (1985a) analyzed data from a 50-year longitudinal study of newlyweds on a series of personality trait dimensions in 1935-1938, 1954-1955 and 1980-1981. Participants rated themselves and were rated by their spouses. Conley found that spouse ratings tended to agree with self-ratings on many personality traits. E. g. , a husband who saw himself as highly conscientious was likely to be viewed as conscientious by his wife as well. Extraversion and neuroticism showed particularly strong longitudinal consistency. Differential continuity in trait ratings was displayed when examining (a) self-ratings over time (b) spouse ratings over time (c) the ability of one kind of rating to predict another kind of rating of the same trait over time. Costa, mccrae, and arenberg (1980) assessed 460 male volunteers in the baltimore longitudinal. +. 70: high stability for the trait of neuroticism.
