Document Summary
Constancy in the quantity or amount of an attribute over time. The consistency of individual differences within a sample of individuals over time, to the retention of an individual"s relative placement in a group. Individuals" relative standing one another on a given dimension. Low differential continuity does not tell us in what direction people change. * absolute continuity and differential continuity are completely unrelated. Remarkably high differential continuity in personality traits over adult lifespan. Ratings that make up the big five dimensions of extraversion & neuroticism. Six temperament dimensions in infants (first year) (rothbart, 1986) Estimates the proportion of variability in a given characteristic that can be attributed to genetic differences between people. Rough estimate of heritability in twin studies h2 = 2 (rmz - rdz) Mz correlation minus dz correlation x 2 h2: hertability quotient rmz: correlation between respective trait scores for mz twins rdz: correlation between respective trait scores for dz twins.
