document: ePsych : interactive demonstrations and experiments in psychology ePsych -LRB- http://epsych.msstate.edu -RRB- , a new Web site currently under active development , is intended to teach students about the discipline of psychology . The site presumes little prior knowledge about the field and so may be used in introductory classes , but it incorporates sufficient depth of coverage to be useful in more advanced classes as well . Numerous interactive and dynamic elements are incorporated into various modules , orientations , and guidebooks . These elements include Java-based experiments and demonstrations , video clips , and animated diagrams . Rapid access to all material is provided through a layer-based navigation system that allows users to visit various `` Worlds of the Mind . '' Active learning is encouraged , by challenging students with puzzles and problems and by providing the opportunity to `` dig deeper '' to learn more about the phenomena at hand
