Active Comparator
No Intervention
Auditory training: temporal cues
Auditory training: non-temporal cues
Passive control group (Aims 1 and 2)
Aim 1: Listeners will hear target acoustic stimuli that vary in a temporal (timing/duration) cue for 9, 1-hour training sessions and will receive correct-answer feedback. Aim 2: Listeners will hear sentences that vary in speech rate for 6, 1-hour training sessions and will receive correct-answer feedback.
Aim 1: Listeners will hear target acoustic stimuli that vary in either stimulus intensity or stimulus frequency during 9, 1-hour training sessions and will receive correct-answer feedback. Aim 2: Listeners will hear speech in varying levels of noise during 6, 1-hour training sessions and will receive correct-answer feedback.
Listeners will be evaluated on pre-training and post-training tests, but will receive no training at all.
