Fast noisy speech: age differences in processing rapid speech with background noise

Article Abstract:

Research suggest that older people are more susceptible to distraction than younger adults, possibly because of an increase in internal neural disturbance, a reduction in the ability to screen out irrelevant stimuli or a change in signal strength. A new study investigates the effects of aging on the ability to process rapid speech accompanied by background noise. It is shown that older adults are less able to ignore background noise than younger people and are less tolerant of rapid speech. It is suggested that the ability to inhibit distracting sounds reduces with age.

Regaining lost time: Adult aging and the effect of time restoration on recall of time-compressed speech

Article Abstract:

Experiments where time was restored to artificially accelerated speech were undertaken. In one experiment both young and older adults's speec recall benefited from the restoration of time, although it failed to increased the older adults to their baseline levels for unaltered speech. In the second experiment the insertion of pauses resulted in either 100% or 125% of lost time, indicating the beneficial effects of time restoration depending on where processing time was inserted.

Response latencies for false memories: gist-based processes in normal aging

Article Abstract:

Three experiments were undertaken in an attempt to investigate the relationship between age-related increase in false memory and gist-based memory strategy. The recognition response latencies were used as activation index of nonrepresented items in memory. Results revealed that age differences in false memory were dependent on gist-based memory processes. In relation to false recognition, younger individuals exhibited reduced tendencies for false perceptions.
