1. To find actual scientific research studies on any topic, add the keyword "method" and add an asterisk * at the end of it. Like this:
handedness method*
2. Use these additional keyword terms and phrases as appropriate: human mechanics, cognitive performance, stress, affect, brain function. For example:
handedness method* affect*
caffeine method* "brain function"
3. Limit the results list to Peer Reviewed
From the column on the left of the Results List, find the Content section and check "Peer Reviewed". This will reduce the results list to only those articles that have been reviewed and approved by other scholars in the field and are therefore, considered the most scholarly of articles. These will be the best research articles available to you.
4. Further limit your results by date and language. Again from the options in the left column, scroll down to Year and further down to Language.
5. If you choose you may further focus your search by using these field commands.
