| Annotation | Paired association recall was tested as a function of serial position for younger and older adults for five word pairs presented aurally in quiet and in noise. In Experiment 1, the addition of noise adversely affected recall in young adults, but only in the early serial positions. Experiments 2 and 3 suggested that older people's recall listening to words in quiet was nearly equivalent to that of younger adults listening in noise. In Experiment 4, the authors determined signal-to-noise ratio (S/N) such that, on average, younger and older people were able to correctly hear the same percentage of words when words were presented one at a time in noise. In Experiment 5, younger adults were tested under this S/N. Compared with older people in Experiment 3, younger adults in this experiment recalled more words at all serial positions. The results are interpreted as showing that encoding in secondary memory is impaired by ageing and noise either as a function of degraded memory representations, or as a function of reduced processing resources.
