Peer-reviewed articles, unlike other articles, go through a rigorous review process in order to report research. You can expect that most of these articles will not provide much background information on your topic; instead they will report on very specific research findings. They take time to publish because of the lengthy review process. It is also worth noting some journals that publish scholarly articles also publish opinion pieces from experts in the field. These opinion pieces do not go through the peer-review process but are often written in a scholarly reaction to scholarly research. Peer-reviewed articles fall into two types: primary research articles, or articles discussing the results of new research, and review articles, or articles that review the literature surrounding a topic. These articles can be based on theory or empirical evidence.
