Dimensions of psychomotor performance: past and future

Motor performance has been examined from various scientific perspectives and with different methodological approaches. In basic research, the main goal is to identify underlying mechanisms that determine performance. This is typically achieved through the analysis of metabolic parameters and, with regard to the central nervous system, neurophysiological measures. When the concept of "motor performance" is expanded to "psychomotor performance," an essential dimension of human behavior comes into focus, namely intentionality. Observable behavior is grounded in metabolic and neurophysiological processes and can be described using measurable parameters. However, explaining behavior in complex situations such as demanding tasks, elevated stress, or dynamic social contexts requires more than the analysis of motor processes alone. Rather, action performance needs to be examined, which integrates purposeful and context-sensitive behavior. Restricting explanations to isolated motor parameters raises questions about their adequacy and practical relevance, particularly when interventions are to be derived from them. As a practice-oriented alternative, this article adopts the concept of ability as its central framework. Psychomotor abilities are understood within an action-oriented and biocultural context. The approach is explored from historical, systematic, conceptual, and empirical perspectives. A theoretically grounded and ability-based model serves as the foundation for subsequent empirical studies that investigate the dimensional structure of the constructs used to explain performance and examines their specific contribution to psychomotor performance. In addition to motor-related factors, cognitive, emotional, and social influences, including parental and school contexts, are considered. Validated behavioral testing instruments and statistical procedures, particularly factor and commonality analyses, are applied to identify distinct dimensions and to determine their explanatory value. The dimensional analysis has three main objectives. First, it seeks to identify constructs as distinct and one-dimensional units. Second, it examines the extent to which these units explain variance in complex physical activity performance. Third, it aims to use empirically validated dimensions as a basis for developing targeted intervention strategies. To achieve these aims, a conceptually coherent and empirically testable structural model was developed, addressing the areas of motor, cognitive, emotional, and social development. The data for the primary study carried out in 1983 were derived from a large sample comprising 342 male 10 year old students, 47 indices, and more than 2000 individual measures, and were subsequently analyzed using statistical procedures. The results allowed us to identify clearly defined variable domains, and to determine their respective contributions to explaining complex psychomotor performance. The findings provided the foundation for numerous subsequent empirical studies between 1991 and 2023, which further refined and extended the model over the following decades. From the beginning, the overarching goal was to improve our understanding of psychomotor performance and to derive practical implications. This orientation towards application is particularly evident in fields related to movement, especially health and sport.
