Learn some of the basic and advanced methods of searching in PsycInfo.
The default settings will search for all terms appearing anywhere in article records.
You can specify additional criteria using the search options farther down on the page. As you can see in the image below, there is an area where you can limit by publication date and restrict your results to articles that are published in peer reviewed journals.
As you continue to go down the page, you will see one of the most popular categories, Methodology, which, among other options, allows you to search for only articles that include an Empirical Study.
Many of these additional options can also be applied on the search results screen. You may want to see how many results you have on a basic search before adding many of these limiters.
