The most important cognitive taxonomy in education is Bloom’s taxonomy. The revised taxonomy has two dimensions. The knowledge dimension consists of factual, conceptual, procedural, and metacognitive knowledge. The cognitive-process dimension consists of remembering, understanding, applying, analyzing, evaluating, and creating. Other taxonomies expand on these cognitive skills to include social and emotional skills such as social engagement, cooperation, and emotional resilience. Still others add ethical, civic, and cultural dimensions. Developing talent in areas such as mathematics, music, and the visual arts requires general cognitive abilities, mental flexibility, and creativity. Motivation and conscientiousness are also needed to support learning and engagement. Predictors of performances in a sample of more than 6,000 athletes revealed that participation in multiple sports is better for superior performances at the adult level. World-class athletes typically participated in multiple sports, began playing their major sport later, and initially reached performance milestones at a slower rate than their competitors.
