Presentation preparation and submission

presentation instructions
Instructions on how to prepare and submit your talk or poster can be found here.

Faculty members, animal behavior professionals, and post-docs are invited to submit a poster, a 5-min talk, or a 10-min talk. Graduate students are invited to submit either a poster or a 5-min talk. [Please note: these instructions may be updated before the 2026 conference].

Undergraduate Students are encouraged to attend CO3 and may present posters if space on the program permits. If an undergraduate student wishes to present a 5-min talk, the student's supervisor must provide a supporting letter. Requests for talks by undergraduate students will be approved at the discretion of the CO3 Program Committee.

Faculty members may request an extended 20-min presentation, expected to integrate several years of empirical research, much of it published. To be considered for an extended talk, a detailed (300-400 word) abstract must be submitted as well as the standard short abstract. The same researcher may not give an extended talk more often than once every three years. Requests for long talks will be approved at the discretion of the CO3 Program Committee.

Faculty members or animal behavior professionals may submit proposals for symposia. The topic of the symposium must fit within the scope of the conference and may consist of up to five presenters (including the organizer). To submit a symposium proposal, the organizer must send a brief abstract (300-400 words) outlining the theme, names of invited presenters and the title of their presentations, by [deadline to come]. Requests for symposia will be approved at the discretion of the CO3 Program Committee.

Things to do in Montréal

Montreal
Montréal, is an exciting city with lots to see and do. Check out their tourism site.

The conference hotel is right in the heart of Downtown, less than a 5 minute walk from Montréal's famed old town, The Notre-Dame Basilica, and the banks of the St. Lawrence River. Just across the road in the other direction is the McGill University campus (in case you miss having an academic setting) and beyond that, the massive Mount Royal Park.

Note that, though it is a Francophone city, everyone in Montréal speaks English, so you won't have trouble communicating.

EDI allies

EDI
The Equity, Diversity, and Inclusion Committee has developed training for CCS members to use to help create a positive environment for all society members. These Allies will be expected to be part of a support network during the conference, and can be clearly identified via an ALLY tag on their name badge. For more information, see the training document.

Learn more about the EDI committee's activities here.

Awards

CCS offers a range of awards tied to CO3, including travel awards, best paper and best poster awards sponsored by the Psychonomic Society.
