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.
Object permanence is the understanding that whether an object can be sensed has no effect on whether it continues to exist. This is a fundamental concept studied in the field of developmental psychology, the subfield of psychology that addresses the development of young children's social and mental capacities. There is not yet scientific consensus on when the understanding of object permanence emerges in human development.
Imitation is a behavior whereby an individual observes and replicates another's behavior. Imitation is also a form of that leads to the "development of traditions, and ultimately our culture. It allows for the transfer of information between individuals and down generations without the need for genetic inheritance." The word imitation can be applied in many contexts, ranging from animal training to politics. The term generally refers to conscious behavior; subconscious imitation is termed mirroring.
Daniel R. Anderson is an American psychologist and a professor emeritus at the University of Massachusetts Amherst. Anderson specializes in developmental psychology and was involved in the creation of children's television series including Allegra's Window, Gullah Gullah Island, Bear in the Big Blue House, Blue's Clues, and Dora the Explorer. He has also acted as an advisor to Captain Kangaroo, The Wubbulous World of Dr. Seuss, Sesame Street, Fimbles, Go, Diego, Go!, It's a Big Big World, Peep and the Big Wide World and The WotWots.
Evolutionary developmental psychology (EDP) is a research paradigm that applies the basic principles of evolution by 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.
Mirroring is the behavior in which one person subconsciously imitates the gesture, speech pattern, or attitude of another. Mirroring often occurs in social situations, particularly in the company of close friends or family, often going unnoticed by both parties. The concept often affects other individuals' notions about the individual that is exhibiting mirroring behaviors, which can lead to the individual building rapport with others.
Andrew N. Meltzoff is an American psychologist and an internationally recognized expert on infant and child development. His discoveries about infant imitation greatly advanced the scientific understanding of early cognition, personality and brain development.
The behavioral analysis of child development originates from John B. Watson's behaviorism.
Infant cognitive development is the first stage of human cognitive development, in the youngest children. The academic field of infant cognitive development studies of how psychological processes involved in thinking and knowing develop in young children. Information is acquired in a number of ways including through sight, sound, touch, taste, smell and language, all of which require processing by our cognitive system. However, cognition begins through social bonds between children and caregivers, which gradually increase through the essential motive force of Shared intentionality. The notion of Shared intentionality describes unaware processes during social learning at the onset of life when organisms in the simple reflexes substage of the sensorimotor stage of cognitive development do not maintain communication via the sensory system.
Carolyn Rovee-Collier was a professor of psychology at Rutgers University. Born in Nashville, Tennessee, she was a pioneer and an internationally renowned expert in cognitive development. She was named one of the 10 most influential female graduates of Brown University. The International Society for Developmental Psychobiology awards the Rovee-Collier Mentor Award in her honor.
Childhood amnesia, also called infantile amnesia, is the inability of adults to retrieve episodic memories before the age of three to four years. It may also refer to the scarcity or fragmentation of memories recollected from early childhood, particularly occurring between the ages of 3 and 6. On average, this fragmented period wanes off at around 4.7 years. Around 5–6 years of age in particular is thought to be when autobiographical memory seems to stabilize and be on par with adults. The development of a cognitive self is also thought by some to have an effect on encoding and storing early memories.
Attentional control, colloquially referred to as concentration, refers to an individual's capacity to choose what they pay attention to and what they ignore. It is also known as endogenous attention or executive attention. In lay terms, attentional control can be described as an individual's ability to concentrate. Primarily mediated by the frontal areas of the brain including the anterior cingulate cortex, attentional control and attentional shifting are thought to be closely related to other executive functions such as working memory.
Vada Harlene Hayne is an American-born academic administrator who was the vice-chancellor and a professor of psychology at the University of Otago in New Zealand, before moving to Western Australia to take up the position of vice-chancellor at Curtin University in April 2021.
In the framework of the Cultural-Historical Activity Theory (CHAT) the leading activity is the activity, or cooperative human action, which plays the most essential role in child development during a given developmental period. Although many activities may play a role in a child's development at any given time, the leading activity is theorized to be the type of social interaction that is most beneficial in terms of producing major developmental accomplishments, and preparing the child for the next period of development. Through engaging in leading activities, a child develops a wide range of capabilities, including emotional connection with others, motivation to engage in more complex social activities, the creation of new cognitive abilities, and the restructuring of old ones.
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.
Sandra L. Calvert is a developmental and child psychologist, whose scholarship illuminates the children's media area, including policy implications. Calvert is currently professor of psychology, and an affiliated faculty member at the McCourt School of Public Policy at Georgetown University. Calvert is also the co-founder and Director of the Children's Digital Media Center, a multi-university research initiative funded primarily by multiple grants from the National Science Foundation, as well as by private foundations. Calvert served as chair of the department of psychology at Georgetown University from 2006 to 2009.
Tiffany Martini Field is professor in the departments of pediatrics, psychology, and psychiatry at the University of Miami School of Medicine and director of the Touch Research Institute. She specializes in infant development, especially with regard to the impact of maternal postpartum depression on mother-infant interaction and the efficacy of massage and touch therapy in promoting growth and emotional well-being in premature and low birth weight infants.
Lauren Bernstein Adamson was a developmental psychologist known for her research on communicative development, parent-child interaction, and joint attention in infants with typical and atypical developmental trajectories. She was a Regents' Professor Emerita of Psychology at Georgia State University.
Daniel Messinger is an American interdisciplinary developmental psychologist, and academic. His research works span the field of developmental psychology with a focus on emotional and social development of children and infants, and the interactive behavior of children in preschool inclusive classroom.
Lorraine E. Bahrick is a developmental psychologist known for her research on intermodal perception and effects of inter-sensory redundancy on learning in infancy and early childhood. Her work in these areas involves investigating how the integration of information from various sensory modalities, such as vision, hearing, and touch, contributes to the cognitive, perceptual, and social development of infants and children. She also explores how the redundancy or overlap of sensory information, influences these developmental processes. She is Distinguished University Professor of Psychology at Florida International University and the Director of Infant Development Lab.
