International Journal of Developmental Sciences

Individual human development is influenced by a multitude of systems, ranging from cultural processes, genetic and physiological incidents up to social interactions. How do these systems cooperate and interact during the course of human development? One of the main goals of Developmental Science is finding an answer to this question. Since it exceeds the means of researchers from individual scientific disciplines to investigate the simultaneous biopsychosocial changes of systems and how they jointly contribute to the social and adaptive functions of human individuals, a new scientific approach is necessary that links the various traditional scientific disciplines under a biopsychosocial approach to describe individual human development: Developmental Science. Developmental Science combines concepts and insights from scientific disciplines which hitherto used to independently tackle the research of human and non-human development. As an interdisciplinary approach it examines individuals across the lifespan with the objective of comprehending the development of individuals with different cultural and ethnic as well as biological background, different economic and cognitive potentials and under diverse living conditions. To facilitate the understanding of developmental processes it is also necessary to overcome the disadvantageous separation of “normal” from “abnormal” human development. Thus, the interdisciplinary field of Developmental Science comprises a holistic approach to understanding how different systems interact and influence development throughout life from genetic and physiological processes to social interactions and cultural processes.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
