‡ Due to missing practical or theoretical relevance, two comparisons (motor performance vs. holistic, multidimensional vs. holistic) have been omitted for economic reasons.§ Significant difference between the classification models (p < .05; false discovery rate adjusted p-threshold: .031; Benjamini and Hochberg, 1995).
