The Department of Human Development was a multidisciplinary department at Cornell University from 1925 to 2021. During its lifetime, the Department led research on developmental science to simultaneously advance theory and improve life. [1] The department emphasized an ecological perspective of human development that examined social, cultural, biological, and psychological processes and mechanisms of growth and change throughout the life cycle and across diverse contexts. Many significant social science scholars of the 20th and 21st century, including Urie Bronfenbrenner (ecological systems theory, co-founder of Head Start) and Kurt Lewin (group dynamics, organizational development), were among the department's faculty. A number of the department's graduate students became significant figures in the social sciences with their work tending toward interdisciplinary and cross-disciplinary approaches.
The department was originally founded in 1925 as the Department of Family Life at Cornell. Its founding occurred during a broader historical context in the United States during the 1920s that saw improving and expanding the science of child psychology and child rearing as a national imperative. [2] It was one of the first university departments established in the United States that focused on child development specifically within the context of the family. [3] Funding from the Laura Spelman Rockefeller Memorial, which was part of a mission by the Rockefeller Foundation to promote social science research and improve child welfare, provided the department with resources to create a laboratory nursery school in which faculty and students conducted empirical research observing the behavior of children and parents. Because of its empirical focus on the home, the family, and children, which were considered women's activities during the time, faculty and students in the department were generally women. Given limited opportunities for programs of study for women during the first half the 20th century, the department offered a particular niche for women at Cornell and helped train a generation of educators, health care providers, and social workers. [4] [5]
In 1945, the department was renamed the Department of Child Development and Family Relationships. Along with the name change came a change in direction for the department as its funding support shifted to government grants and its empirical studies shifted from the laboratory nursery school to surrounding communities. [4] In 1948, Bronfenbrenner joined the department and further expanded its reputation and impact. While a faculty member there, he published his ecological systems theory, which posited that human development unfolds in a nested set of systems, involving cultural, social, economic and political factors in addition to psychological factors. Bronfenbrenner's perspective transformed the study of human development and informed policies related to child development. Notably, Bronfenbrenner's congressional testimony in 1964 and subsequent work on a federal panel helped establish the federal Head Start program in 1965. His influence also shaped the direction and organization of the department and the college in which it was housed. In 1969, the department was renamed the Department of Human Development and Family Studies and Cornell's College of Home Economics was renamed the College of Human Ecology in recognition of Bronfenbrenner's theoretical contributions. [6]
In 1998, the department dropped "Family Studies" from its name and became known just as the Department of Human Development. In part, this change reflected an increasing focus on development across the lifespan. Throughout this time, more male faculty joined the department and the number of male students increased. By 2018, the department had added foci in adolescence, emerging adulthood, adulthood, and aging to its early childhood development roots. Its study of contextual influences had expanded beyond the family to a variety of contexts, including peer groups, schools, neighborhoods, and workplaces, in part due to Bronfenbrenner's theoretical work. There were 25 professorial faculty and approximately 35 masters and doctoral students in residence spanning multiple disciplines and methodologies. [3]
Interdisciplinarity was a defining feature of the department that drew expertise from diverse intellectual and scientific sources. Its mission to conduct interdisciplinary and integrative developmental science to understand the growing person in a changing world was carried out in three interrelated core areas - Law and Human Development, Health and Well-being, and Cognition in Context - that were problem-centered and organized around real-world issues. Some of its signal contributions – such as the creation of Head Start or the launch of the child-witness field – were the result of research syntheses across many of the social sciences as well as medicine, nutrition, and law. [3] The department also placed a great emphasis from the very beginning on the public interests and applied values of research findings, which has motivated evidence-based translational research in modern times. The department promoted and celebrated diversity and inclusion, with one-third of its faculty being ethnic minorities and half of the faculty being women during its final years.
In July 2021, the Department of Human Development and Cornell's Department of Psychology underwent a merger into a cross-university "super-department" that only retained the Department of Psychology in its name. [5] However, undergraduate students at Cornell can still major in Human Development. Human Development coursework at Cornell is organized into five areas of specialization that reflect the strengths of the former department: aging and health; cognitive development; human developmental behavioral neuroscience; psychology, law, and human development; and social and personality development. Human Development coursework also retains the former department's emphasis on the role that social factors, environment, and culture play in human development. [7]
The department's theoretical and empirical contributions reflect the critical perspectives faculty brought from multiple disciplines and can broadly be understood in terms of redefining ecological perspectives as the general field of psychology has developed. [3] Kurt Lewin is often recognized as the father of modern social psychology and is credited with establishing field theory, which proposes that human behavior is a function of an individual's psychological environment, and advancing the study of group dynamics. [8] Bronfenbrenner developed a fundamental theory of the ecology of human development that has shaped the subsequent study of human behavior and human environments . Robert Sternberg is credited with developing a triarchic theory of intelligence, which emphasizes intelligence beyond academic proficiency, and is a vocal critic of standardized testing. [9] The work of Valerie F. Reyna and Charles Brainerd established fuzzy-trace theory, which is a theory of cognition proposed to explain false memory, medical decision making, and risk estimation among other phenomena, and provided practical implications for improving medical communication and eyewitness testimony.
Extension and translational work was an emphasis of the department from its early years . In the 1930s, faculty such as Ethel Waring translated data from empirical studies conducted in the laboratory nursery school in extension bulletins aimed at informing parents on the best child rearing practices. Faculty also educated mothers throughout New York state in Cornell Study Clubs. [4] [10] Faculty have served on federal panels and provided policy recommendations to government agencies, including Bronfenbrenner's work in establishing the Head Start program. Work by Stephen J. Ceci on child testimony and how law enforcement officials interact with children has shaped judicial policy. [11] Work in the department also led to the development of a home visitation program for pregnant and new mothers that serves approximately 58,000 families a year in the United States and is shown to improve health outcomes for mothers and babies, prevent child abuse and improve children's academic outcomes. [5]
Developmental psychology is the scientific study of how and why humans grow, change, and adapt across the course of their lives. 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.
Community psychology is concerned with the community as the unit of study. This contrasts with most psychology which focuses on the individual. Community psychology also studies the community as a context for the individuals within it, and the relationships of the individual to communities and society. Community psychologists seek to understand the functioning of the community, including the quality of life of persons within groups, organizations and institutions, communities, and society. They aim to enhance the quality of life through collaborative research and action.
Ecological psychology is the scientific study of perception-action from a direct realist approach. Ecological psychology is a school of psychology that follows much of the writings of Roger Barker and James J. Gibson. Those in the field of Ecological Psychology reject the mainstream explanations of perception laid out by cognitive psychology. The ecological psychology can be broken into a few sub categories: perception, action, and dynamical systems. As a clarification, many in this field would reject the separation of perception and action, stating that perception and action are inseparable. These perceptions are shaped by an individual's ability to engage with their emotional experiences in relation to the environment and reflect on and process these. This capacity for emotional engagement leads to action, collective processing, social capital, and pro environmental behaviour.

Urie Bronfenbrenner was a Russian-born American psychologist best known for using a contextual framework to better understand human development. This framework, broadly referred to as 'ecological systems theory', was formalized in an article published in American Psychologist, articulated in a series of propositions and hypotheses in his most cited book, The Ecology of Human Development and further developed in The Bioecological Model of Human Development and later writings. He argued that natural experiments and applied developmental interventions provide valuable scientific opportunities. These beliefs were exemplified in his involvement in developing the US Head Start program in 1965. Bronfenbrenner's writings about the limitations of understanding child development solely from experimental laboratory research and the potential for using contextual variability to provide insight into developmental processes was important in changing the focus of developmental psychology.
Ecological systems theory is a broad term used to capture the theoretical contributions of developmental psychologist Urie Bronfenbrenner. Bronfenbrenner developed the foundations of the theory throughout his career, published a major statement of the theory in American Psychologist, articulated it in a series of propositions and hypotheses in his most cited book, The Ecology of Human Development and further developing it in The Bioecological Model of Human Development and later writings. A primary contribution of ecological systems theory was to systemically examine contextual variability in development processes. As the theory evolved, it placed increasing emphasis on the role of the developing person as an active agent in development and on understanding developmental process rather than "social addresses" as explanatory mechanisms.
Socio-ecological models were developed to further the understanding of the dynamic interrelations among various personal and environmental factors. Socioecological models were introduced to urban studies by sociologists associated with the Chicago School after the First World War as a reaction to the narrow scope of most research conducted by developmental psychologists. These models bridge the gap between behavioral theories that focus on small settings and anthropological theories.
Michael E. Lamb is a professor and former Head of the then Department of Social and Developmental Psychology at the University of Cambridge, known for his influential work in developmental psychology, child and family policy, social welfare, and law. His work has focused on divorce, child custody, child maltreatment, child testimony, and the effects of childcare on children's social and emotional development. His work in family relationships has focused on the role of both mothers and fathers and the importance of their relationships with children. Lamb's expertise has influenced legal decisions addressing same-sex parenting, advocating for fostering and adoption by adults regardless of their marital status or sexual orientations. Lamb has published approximately 700 articles, many about child adjustment, currently edits the APA journal Psychology, Public Policy, and Law, and serves on the editorial boards on several academic journals.
Developmental science is an interdisciplinary scientific field that synthesizes perspectives from biology, psychology, and sociology in order to understand behavioral and psychological aspects of human development. The field of developmental science "...is not limited to simply describing deviant behavior at a specific age, but rather examines the dynamic interplay of biopsychosocial risk and protective conditions in the course of development over an individual’s lifespan." It is based on theories previously developed by such psychologists as Jean Piaget, Heinz Werner, and Lev Vygotsky, as well as on dynamic systems theory. In recent years, the field has undergone a paradigm shift away from reductionism to one based on complex, interacting systems, with an increasing emphasis on change over time.
The bioecological model of development is the mature and final revision of Urie Bronfenbrenner's ecological system theory. The primary focus of ecological systems theory is on the systemic examination of contextual variability in development processes. It focuses on the world outside the developing person and how they were affected by it. After publication of The Ecology of Human Development, Bronfenbrenner's first comprehensive statement of ecological systems theory, additional refinements were added to the theory. Whereas earlier statements of ecological systems theory focused on characteristics of the environment, the goal of the bioecological model was to explicate how characteristics of the developing person influenced the environments to which the person was exposed and how they were affected by the environment. The bioecological model is strongly influenced by Bronfenbrenner's collaborations with Stephen Ceci. Whereas much of Bronfenbrenner's work had focused on social development and the influence of social environments on development, Ceci's work focuses on memory and intelligence. The bioecological model reflects Ceci's work on contextual variability in intelligence and cognition and Bronfenbrenner's interest in developmentally instigative characteristics - how people help to create their own environments.
Child displacement is the complete removal or separation of children from their parents and immediate family or settings in which they have initially been reared. Displaced children includes varying categories of children who experience separation from their families and social settings due to several varied reasons. These populations include children separated from their parents, refugees, children sent to boarding schools, internally displaced persons or IDPs, and asylum seekers. Thus child displacement refers to a broad range of factors due to which children are removed from their parents and social setting. This include persecution, war, armed conflict and disruption and separation for varied reasons.

Relationship science is an interdisciplinary field dedicated to the scientific study of interpersonal relationship processes. Due to its interdisciplinary nature, relationship science is made-up of researchers of various professional backgrounds within psychology and outside of psychology, but most researchers who identify with the field are psychologists by training. Additionally, the field's emphasis has historically been close and intimate relationships, which includes predominantly dating and married couples, parent-child relationships, and friendships & social networks, but some also study less salient social relationships such as colleagues and acquaintances.
