1 INTRAINDIVIDUAL CHANGE & VARIABILITY HDFS 597K January 27, 2009 HDFS 597K Applied Longitudinal Data Analysis 5 Objectives for Longitudinal Research (Baltes & Nesselroade, 1979) 1. Direct identification of intraindividual change 2. Identification of interindividual differences in intraindividual change 3. Analysis of interrelationships in behavioral change 4. Analysis of causes (determinants) of intraindividual change 5. Analysis of causes (determinants) of interindividual differences in intraindividual change Intraindividual Change in the 70s – (Buss, 1979) • At the time, it seems, intraindividual change was conceptualized as involving two major components: – change in the level or frequency (rate) of the same class of behaviors across time within an individual, [ quantitative change ] and • “Gains & Losses” (e.g., size of social networks) – interbehavior change or change between different classes of behavior [ qualitative change ] • “Transitions” (e.g., Piaget’s stages) Intraindividual Change in the 80s & 90s – (Nesselroade, 1991) • A distinction made between: intraindividual change (the warp)– • more or less enduring changes that are construed as developmental by virtue of the nature of their antecedents their developmental by virtue of the nature of their antecedents, their consequences, and their correlates, and intraindividual variability (the woof) – • relatively short-term changes that are construed as more or less reversible and that occur more rapidly than the intraindividual changes. Intraindividual Change & Variability The Warp & Woof of the Developmental Fabric (Nesselroade, 1991) Intraindividual Variability Micro-Time Intraindividual Change Macro-Time Magnitude of Attribute learning, development, aging vs. error, instability, inconsistency, lability, noise Weaving Through “the Warp & Woof of the Developmental Fabric” (Nesselroade, 1991) B.

2 Intraindividual Change & Variability Intraindividual Change Intraindividual Variability Ram & Grimm, 2007, IJBD Ram et al., 2005, P&A Growth Curves, etc. Time-Series, etc. Box & Jenkins, 1976; Bryk & Raudenbush, 1987; Joreskog, 1979, McArdle & Epstein, 1987; Meredith & Tisak, 1990 Intraindividual Variability: What is it? P. Mondrian, Tableu I, 1926 Intraindividual Variability: What is it? • Three types of intraindividual variability: (Nesselroade, 2001) Intraindividual Profile Intraindividual Change Intraindividual Variability • Intraindividual Covariation • Intraindividual Dynamics Intraindividual Variability in the 00s (Nesselroade, 2001) • Three types of intraindividual variability : – within-person changes that may or may not be reversible and that may or may not be synchronous across individuals, e.g., development and learning; – “Intraindividual change” – within person changes that are more or less reversible and that may or may not be synchronous across individuals, e.g., states and moods; and – “Intraindividual variability” – patterns of organization such as the salience and frequency of multiple attributes within the individual.
