Repetition priming for famous and nonfamous faces

Created R. Henson, 8/7/00, WDCN & ICN, UCL.

One subject's data from:

Henson, R.N.A., Shallice, T., Gorno-Tempini, M.-L. and Dolan, R.J. (2002)

measured by fMRI. Cerebral Cortex, 12, 178-186.

• 2x2 factorial event-related fMRI
• One session (one subject)
• (Famous vs. Nonfamous) x (1st vs 2nd presentation) of faces against baseline of chequerboard
• 2 presentations of 26 Famous and 26 Nonfamous Greyscale photographs, for 0.5s, randomly intermixed, for fame judgment task (one of two right finger key presses).
• Parameteric factor "lag" = number of faces intervening between repetition of a specific face + 1
• Minimal SOA=4.5s, with probability 2/3 (ie 1/3 null events)
• Continuous EPI (TE=40ms,TR=2s) 24 descending slices (64x64 3x3mm2), 3mm thick, 1.5mm gap
