Abstract
This chapter deals with the genetic analysis of repeated measures. Examples of data that are collected in repeated measures designs include: dietary intake measured over several days or weeks; blood pressure taken under different conditions of rest and stress; psychophysiological data such as EEG that may be sampled with frequencies of 100 Hz or more (i.e., 100 times per second); performance measured during learning experiments; IQ measures taken at several different ages; or behavioral indices of development collected over several years of childhood. Two fundamental questions are important for analysis of these data:
-
1.
Are there changes in the magnitude of the genetic and environmental effects over time? For example, are there changes in heritability?
-
2.
Do the same genetic and environmental influences operate throughout time? For example, are the genes that influence behavior early in life different from the genes that influence the same trait later in life?
