Theories generate hypotheses which are tested through observation of behaviour internally consistent - not generate contradictory hypotheses falsi able - can be proved wrong supported by data - predictions con rmed by research. Particular research with the intention of generalising to a larger population. Sample must be representative of the population of interest. Best approach is to study a random sample drawn from the population. This increases con dence than conclusions will be true for the entire population. Methods varied depending on age group and aspect of development studied. Questions asked in same order so responses be directly compared. Cannot be used with infants or young children. Pros infants and young children who lack verbal skills can be studied. Di cult to isolate behaviour cause as events happen simultaneously. Determine areas of the brain involved in particular cognitive activities. Manipulates some aspect of the environment to see how it a ects participants. Can established unambiguously that one thing causes another.
