Does training with amplitude modulated tones affect tone-vocoded speech perception?

Percentage of correct vocoded consonant identification during pre-training and pre- to post-test.
Learning curves for each group of participants across pre-training (two blocks), and pre- to post-tests of vocoded consonant identification task. Error bars represent +/- 1 standard error. In pre-training1 and 2 (Day 1) participants received online feedback during the task, but not in pre-test or post-test. Note that participants were split into the different groups after pre-training2 based on their mean scores ensuring balanced performance across groups before starting the training regimens. Learning from pre-training1 to pre- training2 was significant for all groups (all z values > 7, all p values < .001), whereas only AM-trained groups showed significant improvement from pre-test (Day2) to post-test (Day4).
