Hello there!
Is it possible to amplitude-modulate by negative values? I’m doing a reinforcement learning study involving amplitudes (i.e., prediction errors) that are scaled from -1 to 1. I think I had some trouble entering the negative amplitudes. Would it be best to scale the amplitudes from 0 to 1 (or otherwise convert to all positive values)?
I’m happy to provide more details or clarification if needed. Thanks very much!
The negative modulators should not matter. Note that
unless you specify otherwise, 3dDeconvolve will de-mean
the modulators.
