Defining Development Development systematic changes and continuities in the individual that occur between conception and death, or from womb to tomb. o Systematic orderly, patterned, and relatively enduring o Continuities ways in which we remain the same or continue to reflect our past selves. 3 Broad Domains: o 1. Physical Development The growth of the body and its organs, the functioning of physiological systems, physical signs of aging, changes in motor abilities, etc. o 2.

Psychosocial Development Changes and carryover in personal and interpersonal aspects of development, such as motives, emotions, personality traits, interpersonal skills and relationships, and roles played in the family and in society.
