To get more targeted results, try PsycINFO and ERIC ERIC (Educational Resources Information Center-EBSCO). The easiest way to access the databases that have Psychology resources is to click on the link "Choose Databases by Subject & Type" on the library home page under the "Database Lists" section. Click on the menu for the first drop down box labeled "All Subjects" and select "Psychology" to see a list of the Psychology databases and a short description of each resource.

Getting you hands on an article when you only have the citation.
A Periodical is anything that is published regularly and includes newspapers, magazines, scholarly journals, as well as some less well-known categories. You will be required by faculty to use articles from peer-reviewed journals in your academic work. What does that mean? Take a look at this information page from San Diego State University for more information on peer-review and a comparison chart for periodicals.
How do you know that what you are finding is acceptable?
And how do you find them in the first place? The best way is to use a database designed to locate scholarly articles in your field of interest.
