It's not 100% clear how you modeled the ratings EV (EV2) in your analysis. Was EV2 just noting the presence of a rating during the 'on' period (i.e., 1-column EV with 1's for each TR during stimulus on and 0's for each TR during stimulus off)? Or did EV2 code discrete values on some scale (e.g., Likert scale) during both the stimulus 'on' and stimulus 'off' periods? For EV1, I assume that you only explicitly coded the stimulus 'on' condition and the stimulus 'off' condition was coded with 0's in the EV?
