Table 1. An outline of the experimental design.

In-phase dot training Counter-phase dot training (total n = 11; n = 6 completed both protocols)
Protocol 1 (n = 7) Protocol 1 (n = 9) Protocol 2 (n = 8)
Pre-training scan: stimuli In-phase dots only In-phase & counter-phase dots In-phase & counter-phase dots
Pre-training scan: task difficulty Same angle only Same angle only Same angle only
Post-training scan: stimuli In-phase dots only Counter-phase dots only In-phase & counter-phase dots
Post-training scan: task difficulty Same and smaller angle Same and smaller angle Smaller angle only

The main experiment employed protocol 1 whereby learning related changes in the response of hMT+ and V1 were compared between two groups, one trained on in-phase dots and the other trained on counter-phase dots. Protocol 2 applied only to the group trained on counter-phase dots and compared the response of hMT+ and V1 to in-phase vs. counter-phase dots pre and post training (within subjects). A total of 11 participants were trained on counter-phase dots and 6 completed both scanning protocols after training. Same angle refers to the angular difference in motion axis orientation that gave rise to 75% correct before training. Smaller angle refers to the angular difference corresponding to 75% correct after training.
