It is of major importance to use psychological tests and questionnaires that are carefully constructed so that their reliability and validity can be determined in different (sub)cultures (Campbell & Tirri, 2004). However, a necessary prerequisite for this is the development of solid conceptual constructs. Otherwise, the researcher runs into the danger of empirically collecting data and loosing touch with reality. A theory-free empirical approach also makes it difficult to relate findings to other psychological research. We first show why and how the Munich Dynamic Ability-Achievement Model (MDAAM) evolved from the Munich Model of Giftedness (MMG). We will then illustrate how the MDAAM can stimulate and structure theoretical and empirical research. The MDAAM can be used as an integrative model of giftedness, talent, expertise, and achievement and could this way bridge the gap between the process-oriented approaches of cognitive studies as well as expertise research and psychometric studies in the field.
