| Summary, etc | A reliable and practical measure of listening effort is crucial<br/>in the aural rehabilitation of children with communication disorders. In<br/>this article, we propose a novel behavioral paradigm designed to measure<br/>listening effort in school-age children based on different depths<br/>and levels of verbal processing. The paradigm consists of a classic word<br/>recognition task performed in quiet and in noise coupled to one of three<br/>additional tasks asking the children to judge the color of simple pictures<br/>or a certain semantic category of the presented words. The response<br/>time (RT) from the categorization tasks is considered the primary indicator<br/>of listening effort.<br/>Design: The listening effort paradigm was evaluated in a group of 31 normal-<br/>hearing, normal-developing children 7 to 12 years of age. A total of<br/>146 Dutch nouns were selected for the experiment after surveying 14 local<br/>Dutch-speaking children. Windows-based custom software was developed<br/>to administer the behavioral paradigm from a conventional laptop computer.<br/>A separate touch screen was used as a response interface to gather<br/>the RT data from the participants. Verbal repetition of each presented word<br/>was scored by the tester and a percentage-correct word recognition score<br/>(WRS) was calculated for each condition. Randomized lists of target words<br/>were presented in one of three signal to noise ratios (SNR) to examine the<br/>effect of background noise on the two outcome measures of WRS and RT.<br/>Three novel categorization tasks, each corresponding to a different depth<br/>or elaboration level of semantic processing, were developed to examine the<br/>effect of processing level on either WRS or RT. It was hypothesized that,<br/>while listening effort as measured by RT would be affected by both noise<br/>and processing level, WRS performance would be affected by changes in<br/>noise level only. The RT measure was also hypothesized to increase more<br/>from an increase in noise level in categorization conditions demanding a<br/>deeper or more elaborate form of semantic processing.<br/>Results: There was a significant effect of SNR level on school-age children’s<br/>WRS: their word recognition performance tended to decrease<br/>with increasing background noise level. However, depth of processing<br/>did not seem to affect WRS. Moreover, a repeated-measure analysis<br/>of variance fitted to transformed RT data revealed that this measure of<br/>listening effort in normal-hearing school-age children was significantly<br/>affected by both SNR level and the depth of semantic processing. There<br/>was no significant interaction between noise level and the type of categorization<br/>task with regard to RT.<br/>Conclusions: The observed patterns of WRS and RT supported the<br/>hypotheses regarding the effects of background noise and depth of<br/>processing on word recognition performance and a behavioral measure<br/>of listening effort. The magnitude of noise-induced change in RT did<br/>not differ between categorization tasks, however. Our findings point to<br/>future research directions regarding the potential effects of age, working<br/>memory capacity, and cross-modality interaction when measuring<br/>listening effort in different levels of semantic processing. |
