AI Article Synopsis
- The study examined how young and elderly adults processed different types of speech materials that varied in length and complexity.
- Time compression was employed to systematically alter speech rates, aiming to test whether processing speed contributes to performance declines in older adults.
- Elderly participants experienced a more significant decline in performance as speech rates increased, with their decline influenced by the complexity of the speech structures used.
Article Abstract
Young and elderly adults heard three types of speech materials varying in both length and degree of semantic and syntactic constraints. Time compression was used to vary speech rates systematically to test a speed of processing hypothesis as one explanation of performance deficits associated with normal aging. In addition to segment length effects, the elderly participants showed significantly steeper rates of performance decline with increasing speech rate, with slope constants dependent on the structural constraints of the speech materials. The results are discussed in terms of processing rate hypotheses and context utilization.
