Developmental psychology is the scientific study of how and why human beings change over the course of their life. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan. Developmental psychologists aim to explain how thinking, feeling, and behaviors change throughout life. This field examines change across three major dimensions, which are physical development, cognitive development, and social emotional development. Within these three dimensions are a broad range of topics including motor skills, executive functions, moral understanding, language acquisition, social change, personality, emotional development, self-concept, and identity formation.
In sociology, socialization is the process of internalizing the norms and ideologies of society. Socialization encompasses both learning and teaching and is thus "the means by which social and cultural continuity are attained".
Old age refers to ages nearing or surpassing the life expectancy of human beings, and is thus the end of the human life cycle. Terms and euphemisms for people at this age include old people, the elderly, OAPs, seniors, senior citizens, older adults, and the elders.
Gerontology is the study of the social, cultural, psychological, cognitive, and biological aspects of aging. The word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek γέρων, geron, "old man" and -λογία, -logia, "study of". The field is distinguished from geriatrics, which is the branch of medicine that specializes in the treatment of existing disease in older adults. Gerontologists include researchers and practitioners in the fields of biology, nursing, medicine, criminology, dentistry, social work, physical and occupational therapy, psychology, psychiatry, sociology, economics, political science, architecture, geography, pharmacy, public health, housing, and anthropology.
Erik Homburger Erikson was a Danish-German-American developmental psychologist and psychoanalyst known for his theory on psychological development of human beings. He coined the phrase identity crisis.
Identity is the qualities, beliefs, personality traits, appearance, and/or expressions that characterize a person or group.
The social cognitive theory of morality attempts to explain how moral thinking, in interaction with other psychosocial determinants, govern individual moral conduct. Social cognitive theory adopts an "interactionist" perspective to the development of moral behavior. Personal factors of the individual, such as individual moral thought, emotional reactions to behavior, personal moral conduct, and factors within their environment, all interact with, and affect each other. Social cognitive theory contests, in many ways, with the stage theories of moral reasoning. Social cognitive theory attempts to understand why an individual uses a lower level of moral reasoning when they are, theoretically, at a higher level. It also attempts to explain the way social interactions help to form new, as well as change existing, moral standards. The influence of modeling and other such social factors are explored as functions of growth and development. Albert Bandura also believes that moral development is best understood by considering a combination of social and cognitive factors, especially those involving self-control.
Erikson's stages of psychosocial development, as articulated in the second half of the 20th century by Erik Erikson in collaboration with Joan Erikson, is a comprehensive psychoanalytic theory that identifies a series of eight stages that a healthy developing individual should pass through from infancy to late adulthood. According to Erikson’s theory the results from each stage, whether positive or negative, influences the results of succeeding stages. Erikson published a book called Childhood and Society around the 1950s that made his research well known on the eight stages of psychosocial development. Erikson was originally influenced by Sigmund Freud’s psychosexual stages of development. He began by working with Freud's theories specifically, but as he began to dive deeper into biopsychosocial development and how other environmental factors affect human development, he soon progressed past Freud’s theories and developed his own ideas.
Developmental stage theories are theories that divide child development into distinct stages which are characterized by qualitative differences in behaviour.
Loevinger's stages of ego development are proposed by developmental psychologist Jane Loevinger (1918-2008) and conceptualize a theory based on Erik Erikson's psychosocial model and the works of Harry Stack Sullivan (1892-1949) in which "the ego was theorized to mature and evolve through stages across the lifespan as a result of a dynamic interaction between the inner self and the outer environment". Loevinger's theory contributes to the delineation of ego development, which goes beyond the fragmentation of trait psychology and looks at personality as a meaningful whole.
A sociological theory is a supposition that intends to consider, analyze, and/or explain objects of social reality from a sociological perspective, drawing connections between individual concepts in order to organize and substantiate sociological knowledge. Hence, such knowledge is composed of complex theoretical frameworks and methodology.
Social learning is learning that takes place at a wider scale than individual or group learning, up to a societal scale, through social interaction between peers. It may or may not lead to a change in attitudes and behaviour.
Identity formation, also called identity development or identity construction, is a complex process in which humans develop a clear and unique view of themselves and of their identity.
Adult development encompasses the changes that occur in biological and psychological domains of human life from the end of adolescence until the end of one's life. These changes may be gradual or rapid and can reflect positive, negative, or no change from previous levels of functioning. Changes occur at the cellular level and are partially explained by biological theories of adult development and aging. Biological changes influence psychological and interpersonal/social developmental changes, which are often described by stage theories of human development. Stage theories typically focus on "age-appropriate" developmental tasks to be achieved at each stage. Erik Erikson and Carl Jung proposed stage theories of human development that encompass the entire life span, and emphasized the potential for positive change very late in life.
Reminiscence therapy is used to counsel and support older people, and is an intervention technique with brain-injured patients and those who appear to have "Alzheimer's and other forms of cognitive disease."
The continuity theory of normal aging states that older adults will usually maintain the same activities, behaviors, relationships as they did in their earlier years of life. According to this theory, older adults try to maintain this continuity of lifestyle by adapting strategies that are connected to their past experiences.
The activity theory, also known as the implicit theory of aging, normal theory of aging, and lay theory of aging, proposes that successful ageing occurs when older adults stay active and maintain social interactions. It takes the view that the aging process is delayed and the quality of life is enhanced when old people remain socially active. The activity theory rose in opposing response to the disengagement theory. The activity theory and the disengagement theory were the two major theories that outlined successful aging in the early 1960s. The theory was developed by Robert J. Havighurst in 1961. In 1964, Bernice Neugarten asserted that satisfaction in old age depended on active maintenance of personal relationships and endeavors.
Primary socialization in sociology is the period early in a person's life during which they initially learn and build themselves through experiences and interactions around them. This process starts at home through the family, in which one learns what is or is not accepted in society, social norms, and cultural practices that eventually one is likely to take up. Primary socialization through the family teaches children how to bond, create relationships, and understand important concepts including love, trust, and togetherness. Several agents of primary socialization involve institutions such as the family, childhood friends, the educational system, and social media. All these agents influence the socialization process of a child that they build on for the rest their life. These agents are limited to people who immediately surround a person such as friends and family—but other agents, such as social media and the educational system have a big influence on people as well. The media is an influential agent of socialization because it can provide vast amounts of knowledge about different cultures and society. It is through these processes that children learn how to behave in public versus at home, and eventually learn how they should behave as people under different circumstances; this is known as secondary socialization. A vast variety of people have contributed to the theory of primary socialization, of those including Sigmund Freud, George Herbert Mead, Charles Cooley, Jean Piaget and Talcott Parsons. However, Parson's theories are the earliest and most significant contributions to socialization and cognitive development.
Aging has a significant impact on society. People of different ages and gender tend to differ in many aspects, such as legal and social responsibilities, outlooks on life, and self-perceptions. Young people tend to have fewer legal privileges, they are more likely to push for political and social change, to develop and adopt new technologies, and to need education. Older people have different requirements from society and government, and frequently have differing values as well, such as for property and pension rights. Older people are also more likely to vote, and in many countries the young are forbidden from voting. Thus, the aged have comparatively more, or at least different, political influence.
