under construction
Cburt_Watcher Version 1
Parameters
Starting with a set of
Cburt_Watcher MVPA
MVPA is implemented online to iteratively select stimuli elicitng similarity (or dissimilarity) in the pattern of activation in fusiform and inferotemporal regions in reference to a target object.
Parameters
Participants are presented with 91 stimuli in a passive viewing task in scanner (16 slice acquisition, 1 sec TR). A target object (in this case a face) is selected as a reference from which to calculate response pattern similarity.
50% of the stimuli eliciting the most similar activation pattern to the reference stimulus are chosen for presentation across 4 successive generations. The aim is to efficiently converge on the stimuli best representing the pattern of activity in the specified region of interest.
