Abstract
The effortfulness hypothesis predicts that as background noise, age and hearing loss increase, the accuracy of memory recognition will decrease. Here we presented young and older adult listeners with sentences at three signal-to-noise ratios in multitalker babble (∞, +15 dB, +5 dB) and probed subsequent recognition memory for these sentences as an offline measure of cognitive processing. Our results confirm the effortfulness hypothesis.
