Writing a literature review

Literature reviews occupy an important corner of the world of scientific activity, yet most scientists do not receive training in how to write them. In the early days of psychological research, many people did their research based on intuitions and personal insights, and one did not have to spend much time in background reading simply because there was not much to read. As our field’s knowledge base expands month by month, however, it becomes increasingly important to be able to master the amount of information already published. New ideas increasingly have to build on previously published works.
