More Sophisticated Thinking: Piaget’s Version
• Concrete-operational period (7-11 years) – Can perform mental operations – actions that can be
performed on objects or ideas that yield a consistent result • Conservation
– Decentration – Reversibility
• Classification • Seriation
– Mental operations are limited to concrete problems in the here and now
• Cannot deal effectively with abstract or hypothetical problems
Formal-Operational Period
• Formal-operational period (11 years to adult) – Can reason abstractly and hypothetically
• Understand that a hypothetical problem need not correspond to the real world

Physical Fitness
• Physical activities promote health • < 50% of U.S. elementary school children
meet national fitness standards • Obesity is epidemic in U.S. children and
adolescents • Multiple risk factors for obesity
– Little physical education class time and its poor use
– Too much time spent in sedentary activities
Participating in Sports
• Sports involvement promotes social skills and self-esteem; helps children learn initiative
• Children playing sports use cognitive skills to devise new game strategies
• Engaging in well-supervised sports plus other adult-led activities is beneficial
• Children lose interest in sports if these are too stressful and when adults overemphasize competition instead of skill development
