Developmental psychology is the scientific study of how and why human beings change over the course of their life. Originally concerned with infants and prepubescent 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: 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.
Attachment Theory is a psychological, evolutionary and ethological theory concerning relationships between humans. The most important tenet is that young children need to develop a relationship with at least one primary caregiver for normal social and emotional development. The theory was formulated by psychiatrist and psychoanalyst John Bowlby.
Otto Friedmann Kernberg is a psychoanalyst and professor of psychiatry at Weill Cornell Medical College. He is most widely known for his psychoanalytic theories on borderline personality organization and narcissistic pathology. In addition, his work has been central in integrating postwar ego psychology with Kleinian and other object relations perspectives. His integrative writings were central to the development of modern object relations, a theory of mind that is perhaps the theory most widely accepted among modern psychoanalysts.
Piaget's theory of cognitive development is a comprehensive theory about the nature and development of human intelligence. It was first created by the Swiss developmental psychologist Jean Piaget (1896–1980). The theory deals with the nature of knowledge itself and how humans gradually come to acquire, construct, and use it. Piaget's theory is mainly known as a developmental stage theory. Piaget "was intrigued by the fact that children of different ages made different kinds of mistakes while solving problems". He also believed that children are not like "little adults" who may know less; children just think and speak differently. By Piaget thinking that children have great cognitive abilities, he came up with four different cognitive development stages, which he put out into testing. Within those four stages he managed to group them with different ages. Each stage he realized how children managed to develop their cognitive skills. For example, he believed that children experience the world through actions, representing things with words, thinking logically, and using reasoning.
Evolutionary developmental psychology (EDP) is a research paradigm that applies the basic principles of Darwinian evolution, particularly natural selection, to understand the development of human behavior and cognition. It involves the study of both the genetic and environmental mechanisms that underlie the development of social and cognitive competencies, as well as the epigenetic processes that adapt these competencies to local conditions.
Developmental psychopathology is the study of the development of psychological disorders with a life course perspective. Researchers who work from this perspective emphasize how psychopathology can be understood as normal development gone awry. Developmental psychopathology focuses on both typical and atypical child development in an effort to identify genetic, environmental, and parenting factors that may influence the longitudinal trajectory of psychological well being.
The model of hierarchical complexity (MHC) is a framework for scoring how complex a behavior is, such as verbal reasoning or other cognitive tasks. It quantifies the order of hierarchical complexity of a task based on mathematical principles of how the information is organized, in terms of information science. This model has been developed by Michael Commons and others since the 1980s.
Organismic theories in psychology are a family of holistic psychological theories which tend to stress the organization, unity, and integration of human beings expressed through each individual's inherent growth or developmental tendency. The idea of an explicitly "organismic theory" dates at least back to the publication of Kurt Goldstein's The organism: A holistic approach to biology derived from pathological data in man in 1934. Organismic theories and the "organic" metaphor were inspired by organicist approaches in biology. The most direct influence from inside psychology comes from gestalt psychology. This approach is often contrasted with mechanistic and reductionist perspectives in psychology.
Heinz Werner was a developmental psychologist who also studied perception, aesthetics, and language.
The behavioral analysis of child development originates from John B. Watson's behaviorism. Watson studied child development, looking specifically at development through conditioning. He helped bring a natural science perspective to child psychology by introducing objective research methods based on observable and measurable behavior. B.F. Skinner then further extended this model to cover operant conditioning and verbal behavior. Skinner was then able to focus these research methods on feelings and how those emotions can be shaped by a subject's interaction with the environment. Sidney Bijou (1955) was the first to use this methodological approach extensively with children.
Stephen W. Porges is a "Distinguished University Scientist" at the Kinsey Institute, Indiana University Bloomington and professor in the department of psychiatry at the University of North Carolina in Chapel Hill in North Carolina. Prior to moving to North Carolina, Professor Porges directed the Brain-Body Center in the department of psychiatry at the University of Illinois at Chicago, where he also held appointments in the departments of psychology and bioEngineering, and worked as an adjunct in the department of neuroscience which he found suited him and it became his priority. Prior to joining the faculty at the University of Illinois at Chicago, Dr. Porges served as chair of the department of human development and director of the institute for child study. He is a former president of the Society for Psychophysiological Research and has been president of the Federation of Behavioral, Psychological and Cognitive Sciences, a consortium of societies representing approximately twenty-thousand biobehavioral scientists. He was a recipient of a National Institute of Mental Health Research Scientist Development award. He has chaired the National Institute of Child Health and Human Development, maternal and child health research committee and was a visiting scientist in the National Institute of Child Health and Human Development Laboratory of Comparative Ethology. He was awarded a patent on a methodology to describe neural regulation of the heart, and today is a lead neuroscientist with particular interests in cranial nerve responses as it relates to both animal and man in which there are specified responses that are physiological in the body. He proposed the polyvagal theory in 1994 providing insight into the mechanism mediating symptoms observed in the brain. The theory has stimulated research and treatments emphasizing the importance of physiological state and behavioral regulation.
Biological psychopathology is the study of the biological etiology of mental illnesses with a particular emphasis on the genetic and neurophysiological basis of clinical psychology. Biological psychopathology attempts to explain psychiatric disorders using multiple levels of analysis from the genome to brain functioning to behavior. Although closely related to clinical psychology, it is fundamentally an interdisciplinary approach that attempts to synthesize methods across fields such as neuroscience, psychopharmacology, biochemistry, genetics, and physiology. It is known by several alternative names, including "clinical neuroscience" and "experimental psychopathology." Due to the focus on biological processes of the central and peripheral nervous systems, biological psychopathology has been important in developing new biologically-based treatments for mental disorders.
Mary Main is an American psychologist notable for her work in the field of attachment. A Professor at the University of California Berkeley, Main is particularly known for her introduction of the 'disorganized' infant attachment classification and for development of the Adult Attachment Interview and coding system for assessing states of mind regarding attachment. This work has been described as 'revolutionary' and Main has been described as having 'unprecedented resonance and influence' in the field of psychology.
Neo-Piagetian theories of cognitive development criticize and build upon Jean Piaget's theory of cognitive development.
Dante Cicchetti is a scientist specializing in the fields of developmental psychology and developmental psychopathology, particularly the conduct of multilevel research with high-risk and disenfranchised populations, including maltreated children and offspring of depressed parents. He currently holds a joint appointment in the University of Minnesota Medical School's psychiatry department, and in the Institute of Child Development. He is the McKnight Presidential Endowed Chair and the William Harris Endowed Chair.
Arnold J. Sameroff is an American developmental psychologist. He researches and writes about developmental theory and the factors that contribute to mental health and psychopathology, especially related to risk and resilience. Together with Michael Chandler he is known for developing the transactional model of development. He is one of the founders of the field of developmental psychopathology.

His wide-ranging areas of scholarship and expertise included clinical assessment, psychoanalysis, cognitive schemas, mental representation, psychopathology, depression, schizophrenia, and the therapeutic process, as well as the history of art. During a long and productive academic career, Blatt published 16 books and nearly 250 articles and developed several extensively used assessment procedures. Blatt died on May 11, 2014, in Hamden, Conn. He was 85.
Juan Pascual-Leone is a developmental neuropsychologist and the founder of the neo-Piagetian approach to cognitive development. He introduced this term to the literature and put forward key neo-Piagetian predictions about mental attention and working memory in the context of developmental growth.
Theodore P. Beauchaine is an American psychologist and professor at The Ohio State University. His research focuses on neural bases of behavioral impulsivity, emotion dysregulation, and self-injurious behavior, and how these neural vulnerabilities interact with environmental risk factors across development for both boys and girls. He is among the first psychologists to specify how impulsivity, expressed early in life as ADHD, follows different developmental trajectories across the lifespan for males vs. females who are exposed to adversity. In contexts of maltreatment, deviant peer affiliations, and other environment risk factors, males with ADHD are more likely to develop conduct problems, substance use disorders, and antisocial traits, whereas females with ADHD are more likely to engage in self-injurious behavior and develop borderline traits. In protective environments, these outcomes are far less likely. Beauchaine has received two awards from the American Psychological Association: the Distinguished Scientific Award for an Early Career Contribution to Psychology and the Mid-Career Award for Outstanding Contributions to Benefit Children, Youth, and Families.
