The 2014 Context and Episodic Memory Symposium (CEMS), now in its tenth year, was held on the campus of the University of Pennsylvania in Philadelphia, PA, on May 8th and 9th, 2014.

The symposium is designed to be a forum for the exchange of ideas among colleagues working on theoretical and empirical approaches to the study of context and episodic memory, broadly construed.


  • We are pleased to announce that Dr. Gordon Bower will be giving the keynote presentation at CEMS 2014!
  • Please visit the page for CEMS 2013 for information on the previous year's symposium, a group photo, and info on the student presenter award.

Location & Hotel

The symposium was held at the Inn at Penn, a Hilton hotel, which also served as the host hotel for the conference.

Registration is available at this link.

Early registration fees (until and including April 30th)* for CEMS 2014 are:

  • $210 for faculty
  • $180 for postdocs
  • $150 for students

* Starting May 1, late registration fees (above plus 25%) will apply. Registration will be available at the welcome desk of the conference via credit card.

The registration fees will cover meeting room rental, A/V costs, breakfast both days, snacks and refreshments, and a reception on the evening of May 8th.

Students and advisors: We have several student travel awards available, similar to last year. In 2013, the awards took the form of registration fee waivers. If you are interested, please DO NOT use the registration link above; instead, e-mail the committee at context.symposium@gmail.com.

Abstract Submission

The format of CEMS is to have a relatively small number of spoken presentations each followed by a commentary given by a scientist working on related problems. The program committee aims to identify submissions that highlight major new theoretical and/or empirical advances. Papers not selected for these spoken presentations can be given as poster presentations. In previous years, posters have been a major highlight of the meeting and have been very well attended. The Bennet B. Murdock award will be given for the best poster or spoken presentation by a young investigator, as determined by the committee.

Abstract submission for talks is closed; the final schedule can be found below. Please e-mail context.symposium@gmail.com if you have any questions.

Information for Presenters

Featured Talks

25 minute talk, 10 minute commentary, up to 10 minutes of questions.

Please either have slides ready to load onto the presentation computer (a Mac with the latest versions of PowerPoint, Keynote, and Adobe Reader) in the morning before your talk, or bring your own computer, with whatever adapters you will need to output a VGA signal.

We will have the capability to output sound from the computer, but please let us know ahead of time to prepare for that.

Data Blitzes

7 minute presentation, followed by 1 minute for quick questions and changeover. (If you finish early you can take additional questions.)


We will have easels, foam core boards, and thumbtacks available for poster display. Please limit posters to 40x60" at most.


If you are presenting and have schedule conflicts, please let us know by emailing context.symposium@gmail.com as soon as possible.
