Cognition and Color Reading Group (Winter 2009) |
Meeting Time and Place: Time is every Friday from Noon till 1:00 (we have the room reserved till 1:30, but most people will probably want to limit it to a one-hour slot). Place is SSPA 2142, which is the small seminar room across from Kim Romney's office.
Choosing a Date to Lead Discussion: Email Kimberly (kjameson@uci.edu) to schedule a discussion date and choose an article. Article links provided below indicate unassigned dates (as "Open") which will be updated as the schedule fills up.
Please encourage others (students, faculty, etc.) to attend who might find this interesting -- The more, the merrier.
