Whether a child is learning to feed himself or a new parent is learning how to make decisions based on more than her own selfish interests, people are always growing and changing.Baltes’ life span developmental theory considers development as adapting toboth gains and losses at all ages of life. There are three types of adaptations that we go through: growth, maintenance, and regulation of loss. We grow when we add new characteristics, understandings, and skills to our behavior repertoire. We show maintenance when we are able to find ways to function at the same level when faced with challenges or when we are able to restore our functioning and “bounce back” after suffering a loss. Regulation of loss is similar to maintenance in that both adaptations involve reorganizing our behavior. However, the unique aspect of regulation of loss involves adjustingour expectations and accepting a lower level of functioning. Growth typically is much more common in childhood than it is in old age, while regulation of loss is much more common in old age than it is childhood (Broderick & Blewitt, 2015). Adult development is influenced by different changes that we must adapt to over the course of life. Age-graded changes refer to the changes that come asa function of time. Some physical changes in adulthood include declines in sensory ability and, more so for women than for men, declines in reproductive ability. Appearance changes as skin wrinkles and sags, and weight gain is common, though not uncontrollable. Cognitive changes that occur with age, such as the capacity of working memory, declines with age
