The American Psychological Association (APA) is a professional organization representing psychologists in the United States. Founded in 1892, it aims to advance the field of psychology through research, education, and practice. The APA also publishes numerous journals and books, providing valuable resources for professionals and students alike. One of the APA's most well-known contributions is the APA Style, a set of guidelines for writing and citing sources in academic papers. This style is widely used in the social sciences, helping to ensure clarity and consistency in scholarly communication.
