Which option is not one of the six information-gathering methods discussed?

• A. Longitudinal surveys
• B. Systematic observation
• C. Psychophysiology
• D. Ethnography

Answer: (A)

When we think about information-gathering methods in development, we focus on concrete techniques for collecting data about behavior, experience, or physiological processes. Longitudinal surveys differ in that they describe a research design: they track the same individuals over time by repeatedly administering surveys to see how things change. The other options map more directly onto data-collection techniques used to observe, measure, or understand behavior and context in the moment or in natural settings. Systematic observation involves watching and recording specific behaviors with a consistent plan; ethnography entails immersive fieldwork to understand culture and practices in context; psychophysiology measures bodily responses to infer mental states. Because longitudinal surveys center on how data are gathered over time rather than representing a distinct information-gathering technique on its own, they’re not counted among the six information-gathering methods discussed.
