Trial timing for multivariate pattern analysis

This data was collected to investigate experimental design optimization for pattern-information approaches to fMRI data analysis. Participants were scanned while encoding images of animals and tools. There were 5 different stimulus presentation designs, and each participant completed to runs under each design. The designs varied in the number of trials and trial timing within fixed duration scans. Trial timing conditions with fixed onset-to-onset timing ranged from slow 12-s trials with two repetitions of each item to quick 6-s trials with four repetitions per item. We also tested a jittered version of the quick design with 4–8 s trials. After the scans, participants completed a memory test.
