Spread of activation psychology
Web16 Oct 2014 · To measure signal spread, we looked at the amount of task-related activation (or de-activation) present in voxels at increasing distances from peak foci. The relative signal changes for these voxels were normalized with respect to the peak value measured with a 3 mm sphere to account for variability in amplitude across subjects. WebSpreading activation serves the function of quicky spreading an associative relevancy measure over declarative memory. It is assumed that activation is very rapidly spread …
