Extra-Credit Opportunities


Additionally, students may gain an additional 20 points (2% of course total) of extra credit through participation as research participants. Students sign up on the ISU Psychology on-line research participation site (SONA; see tutorial links below).  The link for this site is:


Students are expected to respect the sign-up process (that is sign up only once for a particular experiment, and once signed up, to attend and complete their appointment). For each hour of participation a student will get 0.5 percentage points of extra credit (so to get the maximum amount of extra credit, students must participate in 4 hours of experiments). You may allocate your research participation credits to your various classes (that are giving credit for research participation) up until the last day of lectures.

SONA tutorials:

Alternative methods of extra-credit can be done in the form of extra "journal summaries". For this option I would like you to find a research article from a peered review journal (not something like Psychology Today). You should write a brief summary of each major section of the paper, including hypotheses, how they will be tested, what methods are used, what assumptions are being made, how the analysis was done, what the conclusions were, etc. Additionally, I'd like you to include a paragraph which expresses what YOU thought about the paper, what questions still remain in your mind, what you might have done differently, do you have any alternative explanations, etc. Each of these summaries will count as much as one hour of experiment participation. These assignments must also be turned into the instructor no later than the last day of lectures.

So to get full extra credit you may do:

    4 hours of experiment participation
    4 extra journal summaries
    some combination of these options (e.g., 3 journal summaries and one hour of experiment participation).
