The Effect Of Comprehension Feedback And Listener Age On Speech Complexity, Tara Lineweaver, Paul Hutman, Christopher Ketcham, John Bohannon
Tara T. Lineweaver
Forty college-aged participants told a story and gave verbal walking directions to either a same-age peer or a 75-year-old adult. The listeners gave some participants comprehension feedback and gave other participants mixed comprehension and noncomprehension feedback. Analyses examined length of utterance immediately preceding or following feedback cues. Participants did not globally simplify their speech when talking to the older compared with the young adult. However, speech was sensitive to comprehension feedback from both listeners, and listener age affected speech complexity by influencing the magnitude of this fine tuning effect. Participants simplified their speech more in response to feedback cues from …

Aging Of Attention: Does The Ability To Divide Decline?, T. Salthouse, N. Fristoe, Tara Lineweaver, V. Coon

Previous research has yielded conflicting results regarding the relationship between adult age and the ability to divide attention between two concurrent tasks. At least some of the inconsistency is probably attributable to methodological variations, such as the manner in which divided-attention ability has been assessed, how single-task performance has been considered, and the degree of control over relative emphasis placed on each task. Two experiments employing procedures sensitive to these concerns were conducted in which a speeded decision task was performed during the retention interval of a letter-memory task. The results of both experiments indicated that there were relatively few …
