The Online Psychology Laboratory (OPL) represents the first National Science Foundation funded entry for psychology in the National Science Digital Library. The APA Education Directorate also provides support for this project. OPL currently offers classic studies in psychology that students can participate in, and then analyze data from the experiences. As OPL continues to develop, new materials will be added to enhance learning about the discipline of psychology in high school, community colleges, and universities. You can search for materials using Keywords, Topic, and Method of Analysis. Keyword searches examine all fields and return results consistent with your search. You may also browse by topic; a broad listing of topics in psychology is displayed, allowing for a materials search within that area. Browsing by method allows for searches based on research methodology.
