The psychology of development of human throughout his life developing worldwide after 1970 strongly emphasizes the interest in human in all phases of his life. The holistic attitude of the life-span psychology – manifested in the approach to human as a person – a multidimensional, but irreducible being, who functions in many areas, but always in a holistic way, and also a being that develops in a customized manner and without exception at every stage of life - helped to formulate many new detailed research problems. The scope of these research interests has also been extended to people with intellectual disabilities who increasingly take on social roles that are assigned to adults and perform developmental tasks assigned to a particular phase of life. Also, they increasingly reach late maturity, as the time of their dying gradually progresses.
