Week 6: lecture #6: wednesday february 11, 2015. Part i. continuity / coherence of personality: continuity of personality. Do individual diff in some attribute preditct individual diff in that same attribute at some later point in time? (x1 x2: coherence of personality. Do individual diff in some attribute predict individual diff in some other attribute at some later point in time? (y1 y2) (james) by age 30: roberts & delvecchio (2000): Meta-analyzed findings from 152 longitudinal studies involving a total of 3,217 consistency coefficients and 50,207 participants. Meta-analysis, averaging data across diff studies: roberts & delvecchio (2000) continued: Consistency increased as a function of age. Holding time interval constant at 6. 7 years, consistency coefficients equaled: Time interval is constant, time assessed is diff. Late adulthood has much more stability in personality. Principle/ rule #1: consistency increases an a function of age: roberts & delvecchio (2000) continued: Consistency decreased as a function of time interval.
