Call for Papers

deadline July 31, 1998

The workshop on Object Perception and Memory (OPAM) is an opportunity for researchers in visual perception and memory to present their most recent work. As is its tradition, the 1998 meeting of OPAM will take place the day before the Psychonomic Society Meeting in Dallas, Texas in the conference hotel. This notice is to encourage you to attend and to consider presenting your research on object/scene perception, recognition, and memory. Papers will be selected according to the following guidelines: 1.) To ensure that we hear as many ideas as possible, greater priority will be given to those who did not present last year. Graduate students will be given priority over post-docs, who will in turn be given priority over faculty (since the latter two groups should be able to present at Psychonomics). In the event that we have more submissions than available time slots, it may also become necessary to review submitted presentations. If so, submissions will be rated in terms of appropriateness to the topic of the meeting, general interest, and quality.

Student Travel Grants

One and perhaps two travel grants (depending on the funds available) will be awarded to outstanding submissions. Preference will be given to presenters who do not have other means of travel support to attend this conference.


Please send submissions to Dan Levin or Alice O'Toole (addresses below) by Friday, July 31, 1998, either by electronic mail (preferred) or regular mail (late submissions will also be considered, but be given lower priority). All talks will be 15 minutes long, with an additional 5 minutes for discussion.

We will arrange to have an overhead projector and a slide projector available for the presentations. If necessary and monetarily feasible, we may be able to provide a TV/VCR; please let us know as soon as possible if you would like to make a presentation that requires a dynamic display. In order to pay for the conference room and AV euipment, it will be necessary to collect a registration fee ($25 for faculty, $15 for grad students and post-docs) from all attendees.

You may send the registration fee with your submission or pay at the door. Please make checks out to Dan Levin. In addition to the program of presentations this year we will be holding a community dinner for all who would like to attend. Details will be available this summer. Please circulate this information as widely as possible. Thanks for your support, and we hope to see you at OPAM-98!
