Peer review is the process in which scholarly works are evaluated by experts in the field before publication. Watch the video for more information.
Look for the Peer Reviewed symbol (circled in green above), located below an article title on your results list.
You can also filter results for Peer-reviewed journals and articles by using the "Peer-reviewed Journals" filter, located under the "Tweak my results" menu (above image). Just be sure to hit the green "apply filters" button at the bottom of the page after selecting!
