Developmental Psychology

Developmental Psychology


"Developmental psychology can be defined as the discipline that attempts to describe and explain the changes that occur over time in the thought, reasoning and functioning of a person due to biological, individual and environmental influences. Developmental psychologists study children's development, and the development of human behavior across the lifespan, from a variety of perspectives."


(Alan Slater & Gavin Bremner)


A useful way of understanding the scope of developmental psychology is provided by The Journal of Applied Developmental Psychology, the primary focus of which concerns the publication of research relating to two key concepts.


Human Development: The transformations and changes that occur during the life cycle and the processes or mechanisms which influence individuals' behavioral, cognitive, emotional, and moral development.


Application: How the knowledge gained from research can be applied to the improvement of developmental outcomes, such as through policy making or within educational, clinical, and social settings. 


Key Figures in The History of Developmental Psychology



William T. Preyer (Jul 4, 1841 - Jul 15, 1897)



William T. Preyer


A pioneer in the field of developmental and child psychology, William Preyer published the first comprehensive book on the topic 'The Mind of the Child' in 1881.


Preyer was renowned for employing innovative and scientifically rigorous research methods, the legacy of which continues today via the 'William Thierry Preyer Award' presented by the European Society on Developmental Psychology for excellence in research of human development.



Mary Ainsworth (Dec 1, 1913 - Mar 21, 1999)



Mary Ainsworth


A hugely influential developmental psychologist, Mary Ainsworth is best known for her career-long research partnership with John Bowlby and her pioneering work on child developmental psychopathology. Among her many professional honors, Ainsworth received the American Psychological Association Award for Distinguished Scientific Contributions in 1989 and the American Psychological Foundation Gold Medal Award for Life Achievement in the Science of Psychology in 1998, the official citation for which read: 


"Mary Ainsworth stands out as one of the major figures of the twentieth century in the study of the relations between young children and their care-givers. Her work on the nature and development of human security, her exquisite naturalistic observations of attachment-care-giving interactions, her conceptual analyses of attachment, exploration and self-reliance, and her contributions to methodology of infant assessment are cornerstones of modern attachment theory and research. The patterns of attachment that she identified have proven robust in research across diverse cultures and across the human lifespan. Her contributions to developmental psychology, developmental psychopathology, and ultimately to clinical psychology, as well as her teaching, colleagueship, and grace, are the secure base from which future generations of students can explore."
