Introduction
Every developmental psychologist works within a theoretical perspective, a lens through which to look at the child. At times the perspective is explicitly stated, at other times it is implicit and unspoken. Each perspective includes assumptions about the processes of human development, the roles of nature and nurture in development, whether development is a continuous or a discontinuous process (see Figure 1.1), what causes individuals to differ from one another in their psychological characteristics, and the appropriate ways to conduct research.
Over the past one hundred years, roughly the time that psychology has existed as a recognized science, developmental psychology has passed through five broad theoretical perspectives. In this chapter I summarize each in turn, highlighting some important people in each, and then compare them. The five perspectives, and the span of greatest influence for each, are as follows:
- Genetic psychology: 1890sâ1950s
- Behaviorism: 1930sâ1950s
- Cognitive developmental psychology: 1957âtoday
- Constructivism: 1950sâtoday
- Cultural psychology: 1980sâtoday

1.1 Genetic Psychology
When psychology first became a discipline separate from philosophy, at the end of the nineteenth century, the study of child development had a central place. The predominant theoretical perspective placed emphasis on endogenous factors: influences inside the child. The study of childrenâs growth and development was called âgenetic psychology,â where the term âgeneticâ referred not to the genes (nothing was known about chromosomes at that time) but to a focus on origins.
1.1.1 Granville Stanley Hall
Granville Stanley Hall (1844â1924) was the first person to obtain a doctoral degree in psychology in the United States (studying with William James at Harvard University). Hall was one of the more colorful people in the history of developmental psychology, and he is credited with initiating the systematic study of childrenâs development. Hall became the founder of the American Psychological Association, and its first president. He traveled extensively and studied in Europe, taught at Harvard University and Johns Hopkins University, and became president of Clark University.
Hall was influenced by both Sigmund Freud and Charles Darwin. In his view, a childâs development involves recapitulation: the individual relives the evolutionary stages of the history of their ârace.â For Hall, a childâs development is biological not in the sense of resembling the blossoming of a flower, but because the individual traces a pathway that was first defined by the evolution of the species. In his view âthe child and the race are each keys to the other.â
Today we know that all the humans on planet Earth are very similar genetically. There is no evidence to support the idea of biologically distinct races. But Hall was writing at a time when this fact was not known, and he insisted that psychologists should search for the traces, the fossils, of earlier forms of our âsoul life.â This was, after all, Darwinâs method: to describe the anatomical traces of earlier creatures in those living today, as well as in the fossils of extinct species. For Hall, it is not a childâs society or culture that defines how she will grow up, but her biological inheritance, and in his view this reflects her race.
Hall believed that the habits and codes of conduct of their ancestors are the source of modern humansâ temperamental dispositions, our âinstinct-feelings.â He proposed that human development operates on these dispositions, on a level deeper than that of intellect.
It might seem that Hall was a determinist, believing that psychological development is completely determined by heredity. But in fact he was quite aware of the interaction between organism and environment. Indeed, Hall was worried that in certain environments psychological growth can become too rapid and unnatural: our âunbalanced, hot-house life ⌠tends to ripen everything before its timeâ (Hall, 1904, p. xi). He also wrote of the ways civilization represses and corrupts development; he believed that modern life creates, in his famous phrase for the turbulence of adolescence, too much âstorm and stress.â
For Hall, then, culture is not a resource for psychological development but a source of corruption. He considered it important to search for âtrue norms against the tendencies to precocity âŚâ (1904, p. viii). Listening to the echoes of the âvaster, richer life of the remote past of the raceâ might save us from this âomnipresent danger of precocityâ (1904, p. xi).
Consequently, Hall did not believe that humans have a biologically fixed nature. On the contrary, he wrote that âMan is rapidly changing,â and âman is not a permanent type but an organism in a very active stage of evolution toward a more permanent formâ (1904, p. vii). In his view the laws of human growth might be fixed, but humans are continually changing as a result of those laws. The human species, in fact, is âstill adolescent in soul.â
Hall viewed child development, then, as a passage through developmental stages which corresponded with stages in the evolution of the childâs ârace.â The period of infancy and early childhood resembles, in Hallâs eyes, the time of our remote animal ancestors. Middle childhood corresponds to what he called the âpigmoidâ stage of evolutionâan age, in his view, at which the child enjoys activities such as hunting, fishing, fighting, roving, idleness, and playing. The country is the proper environment for a child of this age, and âBooks and reading are distasteful, for the very soul and body cry out for a more active, objective life, and to know nature and man first hand.â
Adolescence, in contrast, is âa marvelous new birthâ (1904, p. xv) when âthe higher and more completely human traitsâ appear (1904, p. xiii). Nature âarms youth for conflictâ; in adolescence we see the changes that make men aggressive and prepare women for maternity. Adolescence is the time of a âreconstructionâ and a changing of the relations among âpsychic functions.â Sex now âasserts its masteryâ and âworks its havocâ (1904, p. xv). The adolescent âcraves more knowledge of body and mindâ; he âwakes to a new world and understands neither it nor himself.â These new powers must be âhusbanded and directed,â for at this age âeverything is plasticâ (1904, p. xv).
1.1.2 Arnold Gesell
Another significant figure in the genetic perspective, a generation later than G. Stanley Hall, was Arnold Gesell (1880â1961). Gesell worked at the Yale University Clinic for Child Development. Where Hall was a Romantic, Gesell, in contrast, was interested in the rational, ordered, and self-disciplined aspects of human nature. For him, the scientific study of childrenâs development should be based on empirical facts, not on images of a distant life of the soul.
Despite their differences, Gesell, like Hall, emphasized the role of biological maturation in childrenâs development. In an article written for the Encyclopedia of the Social Sciences Gesell proposed that development is essentially growth: âGrowth is itself a unifying concept which removes undue distinctions between mind and body, between heredity and environment, between health and disease and also between separate scientific disciplinesâ (Gesell, 1930, pp. 392â393). He also stated that âlike the heavenly bodies the human life cycle is governed by natural laws. In surety and precision the laws of development are comparable to those of gravitationâ (1943, p. 59). In his view, the phenomena of growth âare subject to general and unifying laws which can be formulated only by coordinated contributions from several scientific domainsâ (1930, p. 392).
Gesell viewed development as a movement through distinct stages, but he insisted that it proceeds not âin a staircase manner or by installments. It is always fluent and continuousâ (Gesell et al., 1943, p. 61). He saw development as the result of an interaction between child and environment. However, the basic characteristics of each developmental stage are, in his view, the products of an evolutionary process in which new qualities are acquired and then handed down.
Although Gesell emphasized that the infant âis a biological fragment of nature,â he saw that âhe is also meshed in a web of human relationships,â and maintained that âthe system of child psychology which any culture achieves is an index of that culture.â He proposed that child psychology leads to âa deeper comprehension of the process of social organization itself.â Gesell himself undertook a series of highly detailed studies of childrenâs development and put children under the microscopeâor at least under the film camera. His laboratory housed a dome under which children of different ages were observed objectively and filmed for detailed analysis of their behavior.

Gesell thought of the scientific disciplines of psychology and biology as linked, in a scientific division of labor. He envisioned psychology becoming psychobiology, and producing a âpsychotechnologyâ of testing and assessment. In time, he predicted, âthe early span of human growth will come more fully under social control,â and âthis is only the beginning of a policy of health supervision.â In his view, then, the goal of scientific developmental psychology was to discover laws of growth to achieve âa constructive and preventive supervision of human infancyâ (1930, p. 393). He believed that, âWith the employment of scientific method, however, errors are being steadily reduced and the manifold problems of child development are approached in a new spirit of rationalismâ (1930, p. 391).
1.1.3 Erik Erikson
Another key figure whose work had its roots in the genetic perspective, though it moved beyond this perspective, was Erik Erikson (1902â1994), who trained as a Freudian psychoanalyst at the Vienna Psychoanalytic Institute. After moving from Europe to the USA Erikson worked to articulate a âpsychosocialâ model of development, which expanded Freudâs psychosexual account of childrenâs development to include attention to the culture in which a child develops. He wanted to create a psychoanalysis that was âsophisticated enough to include the environmentâ (Erikson, 1994b[1968], p. 24).
Erikson viewed human development as a life cycle that passes through distinct stages. Each stage has its own dynamics, the result of âthe laws of individual development and of social organizationâ (Erikson, 1994a[1959], p. 7). In addition, each stage involves a distinct kind of crisis. By âcrisisâ Erikson meant âa necessary turning point, a crucial moment, when development must move one way or another, marshaling resources of growth, recovery, and further differentiationâ (1994b[1968], p. 16). He proposed that every stage involves a culturally defined âmoratoriumâ (a temporary delay) during which the individual is given time to master the challenges of that stage, and during which social institutions provide guidance. Each moratorium is a period during which the potential crisis of the stage can be resolved. If the crisis is not resolved, there will be challenges for future development.
