Selected articles to be posted on this web site under Schedule.


Course goals:

  • Understand how research is conducted and evaluated in cognitive science
  • Distinguish experiments vs. observations
  • Understand when you can and can’t infer causality
  • Gain fluency with sources for finding research articles and data resources
  • Grasp basic types of data and how they can be analyzed
  • Be able to identify basic types of research designs
  • Know situations when certain research designs are more/less appropriate
  • Become sensitive to potential pitfalls (confounds, nuisance variables, participant attrition, carryover effects) of different types of research


Course policies:

  • Assignments are due at the beginning of class. Late work will be penalized.
  • Readings are required. If expense is an issue, please try to find someone to share the book with or take a look for books on reserve in the library.
  • If you have an emergency that prevents you from turning in an assignment, contact Professor Creel as soon as possible to make alternative arrangements.
  • Podcasts (if provided) and posted lecture slides are not intended as a substitute for attending lectures and engaging in the class.
  • If you miss a lecture, it is your responsibility to consult one of your fellow students to get notes.
  • Academic honesty is of the greatest importance. See guidelines below.
  • Please refrain from using electronic devices for any non-class purpose. It is disrespectful and distracting to other students to tweet, check Facebook, etc. in the middle of a course (Sana, Weston, & Cepeda, 2013, Computers and Education). If this becomes a persistent problem, expect to be called on to share the contents of your electronic device!

Academic honesty

The crux of academic integrity: Your work should be your own. If you turn in something that is not indicative of your performance, you are doing a disservice to yourself in failing to actually learn the material. Relatedly, if you do someone else’s work for them, you are allowing them not to learn material. At a more practical level, you are doing something that, if caught, instructors are obligated to report to your college.

Overall, you should never copy someone else’s ideas or work.

If you’re not sure, it’s better to ask now than to risk trouble later. Just asking won’t get you in trouble.

Examples of things that are permissible:

  • Studying in groups. (In fact, this is often a good strategy!)
  • Talking about articles or class material in groups.
  • Referencing material in the book (or an article) and noting that you have done so.

Examples of things that are NOT permissible:

  • Looking at someone else’s exam.
  • Using materials on an exam that are not permitted.
  • Writing papers in groups. This includes taking someone else’s paper (or parts of it) and quoting verbatim, or changing a small number of words. The work you turn in should be your own interpretation and your own thoughts.
  • Writing a paper for someone else.
  • Copying someone else’s paper.
  • Referencing material in article/book without noting that you have done so.
  • Quoting a large proportion of your paper from the article (more than 5-10% of your paper directly quotes the original author). While you are giving credit to the author, this kind of “quote abuse” (Carver, 2010, personal communication) is counter to the purpose of written assignments, which is to demonstrate that you understand the material by evaluating it in your own words.
