Ours is the only species to be able to communicate ideas to others through a written language. This ability also allows humans to express their creativity, which is another characteristic that is typically human. The recording and exchange of ideas using the written word is an important part of how we pass information on from one generation to the next. The average time spent reading at various ages is given in the table below.

Abraham Maslow, a famous psychologist, created a hierarchy of human needs. He said that humans must fulfil their basic needs, like the need for food and water, before experiencing higher-order needs. Higher-order needs include those related to self-esteem (e.g. the need to feel confident) and to self-actualization (e.g. the desire to be creative or to find purpose in life). While many species share the lower-order needs, it is humans alone who can strive to be the best that they can be. The data in the table below relates to the human need for safety.
