Abstract

Psychologists who study human development have adopted the lifespan perspective, which maintains that important changes occur during every period of development and that these changes must be interpreted in terms of the culture and context in which they occur (Boyd and Bee, 2009). Prior to this understanding, the subject of development was limited to childhood. This view has shifted because it is evident adults continue to experience major life changes and there has been a significant increase in age expectancy. Therefore, all stages of life are equally important. Lifespan development begins at the time of conception and continues up until the moment of death. In 2009, Boyd and Bee postulated that the lifespan perspective is characterized by plasticity, interdisciplinary research, and a multi-contextual view of the nature of development. Boyd and Bee also identified a number of key issues that play an essential role in lifespan development.
