  Toys, like play itself, serve multiple purposes in both humans and animals. They provide entertainment while fulfilling an educational role. Toys enhance cognitive behavior and stimulate creativity. They aid in the development of physical and mental skills which are necessary in later life.
  
  Wooden blocks, though simple, are regarded by early childhood education experts such as Sally Cartwright (1974) as an excellent toy for young children; she praised the fact that they are relatively easy to engage with, can be used in repeatable and predictable ways, and are versatile and open-ended, allowing for a wide variety of developmentally appropriate play. Andrew Witkin, director of marketing for Mega Brands, told Investor's Business Daily that "They help develop hand-eye coordination, math and science skills and also let kids be creative." Other toys like marbles, jackstones, and balls serve similar functions in child development, allowing children to use their minds and bodies to learn about spatial relationships, cause and effect, and a wide range of other skills.
  
  One example of the dramatic ways that toys can influence child development involves clay sculpting toys such as Play-Doh and Silly Putty and their home-made counterparts. Mary Ucci, Educational Director of the Child Study Center of Wellesley College, has demonstrated how such toys positively impact the physical development, cognitive development, emotional development, and social development of children.
  
  Toys for infants often make use of distinctive sounds, bright colors, and unique textures. Through repetition of play with toys, infants begin to recognize shapes and colors. Play-Doh, Silly Putty and other hands-on materials allow the child to make toys of their own.
  
  Educational toys for school age children of often contain a puzzle, problem-solving technique, or mathematical proposition. Often toys designed for older audiences, such as teenagers or adults, demonstrate advanced concepts. Newton's cradle, a desk toy designed by Simon Prebble, demonstrates the conservation of momentum and energy.
  
  Not all toys are appropriate for all ages of children. Even some toys which are marketed for a specific age range can even harm the development of children in that range, such as when for example toys meant for young girls contribute to the ongoing problem of girls' sexualization in Western culture.
  
  A study suggested that supplying fewer toys in the environment allows toddlers to better focus to explore and play more creatively. The provision of four rather than sixteen toys is thus suggested to promote children's development and healthy play.
