In longitudinal research, the same people are studied over a period of time. Longitudinal research is particularly useful in studying developmental trends that occur over a long age span. Both longitudinal and cross-sectional researchers must bear in mind that research on a cohort may not be valid for people developing in an earlier or later cohort. In cross-sequential research, several groups of people at different ages (crosssectional component) are followed over time (longitudinal component). Correlation is a number indicating the degree of relationship between two variables. A correlation is positive if both variables tend to increase together or decrease together, negative if one variable tends to increase when the other decreases, and zero if no connection is evident. Correlation does not prove causality. Because numbers can be easily summarized and compared, scientists often rely on data produced by quantitative research. This method may be particularly limiting when researchers describe child development. Also, many developmental researchers use qualitative research that asks open-ended questions. Evaluation: A. Developmental Fact or Myth? True or False. 1. The science of human development is the study of how and why people change as they grow older, as well as how and why they remain the same. 2. A small change in behavior can have a large impact on the
