摘要:When it comes to high cognitive ability assessment, traditional “IQ-diagnosis” has not proven to be particularly helpful. Psychological assessment aimed at promoting the development of gifted individuals requires a scientifically based theoretical model that identifies which cognitive strengths are necessary and which weaknesses can be compensated, and that takes the moderating effects of personality and environment into account when describing the interplay between ability and achievement. While such models – including the one described in the following paper – do exist, they currently lack an adequate theoretical foundation or at least a convincing empirical validation. Science still stands before the challenge of offering appropriate psychodiagnostic instruments to measure model components while fulfilling practitioners’ requirements. The following work describes a prototypic example of how such requirements might be met for ability testing. Yet in terms of personality and environmental variables, particularly caregiving, currently available methods are wholly unsuitable for meeting intended goals. Systematic behavioral observation offers a possible solution. Its validity, objectivity, comprehensiveness and efficiency in terms of high ability testing – as well as that of interview guides – must, however, be further explored.
