The goal of this study is to identify how auditory duration discrimination ability varies across age groups by using an unbiased stimulus such as a music tone. This will be accomplished by conducting a quantitative study testing duration discrimination skills in young and elderly adults. Their confidence ratings per response will also be included along with their discrimination results. The author will generate data that compare the duration discrimination abilities of young versus elderly adults. The null hypothesis is that there is no difference in duration discrimination between elderly and young adults.
