The effect of aging on context use and reliance on context in speech: A behavioral experiment with Repeat-Recall Test.

ABSTRACT:

Purpose

To elucidate how aging would affect the extent of semantic context use and the reliance on semantic context measured with the Repeat-Recall Test (RRT).

Methods

A younger adult group (YA) aged between 18 and 25 and an older adult group (OA) aged between 50 and 65 were recruited. Participants from both the groups performed RRT: sentence repeat and delayed recall tasks, and subjective listening effort and noise tolerable time, under two noise types and seven signal-to-noise ratios (SNR). Performance-Intensity curves were fitted. The performance in SRT50 and SRT75 was predicted.

Results

For the repeat task, the OA group used more semantic context and relied more on semantic context than the YA group. For the recall task, OA used less semantic context but relied mo
