Greater explicit cognitive resources support speech-in-noise identification in elderly normal-hearing listeners
2015 (English)Conference paper, Poster (Refereed)
Prior studies have demonstrated that cognitive capacity of listeners is a key factor in speech-in-noise tests in young-normal-hearing listeners (e.g., Moradi et al., 2014) and hearing-impaired individuals (e.g., Foo et al., 2007; Rudner et al., 2012). In addition, aging is associated with decline in sensory and cognitive functions that may impair speech perception in noisy conditions.
The present study aimed to investigate the relationships between working memory and attentional capacities and speech-in-noise identification in elderly normal-hearing listeners. Twenty-four native Swedish speakers (13 women and 11 men) normal hearing were recruited to participate in the study. The mean age of participants was 71.5 years (SD = 3.1 years, range: 66–77 years). The reading span test (RST) and the Paced Auditory Serial Attention Test (PASAT) were used to measure working memory capacity and attentional capacity, respectively. The speech-in-noise identification measured using the HINT (at 50% correct level) and Hagerman test (at 80% correct level). Results showed that individuals with greater working memory and attentional capacities had better performance in HINT and Hagerman tests. These findings support the notion that explicit cognitive resources of listeners play a critical role in identification of speech stimuli under degraded listening conditions.
