![]() One promising approach that might bring new evidence of top-down control processes on the auditory system is the dichotic listening paradigm (DL), more specifically, the clinical use of non-forced and forced recall on DL tests. The controversy has mainly involved the lack of strong evidence of impaired processing in the auditory system, the heterogeneous nature of APD, with varied symptoms and extensive comorbidities, and the lack of a gold standard for diagnostic accuracy, including the challenge involving the influence of high-order cognitive functions on auditory processing tasks. The role of the additional cognitive processes such as inhibitory control in LD is discussed.ĭespite decades of research, auditory processing disorder (APD) is still a topic of intense debate and controversy. However, the WM, although impaired in the LDG group, was not the main factor in segregating both groups. These results indicate that LD presented by the LDG might be due to a combination of sensory and cognitive deficits, with emphasis on the cognitive component. Both groups presented an overall right ear advantage with no difference in terms of the magnitude of advantage. This same result was observed when controlling for working memory (WM) variance. The results indicated an overall significantly worse performance of LDG compared to the CG, which was greater for forced-left condition. We assessed the performance of a listening difficulties group (LDG) ( n = 24, mean age = 24, backward digit span = 4.0) and a control group (CG) ( n = 25, mean age = 29.2, backward digit span = 6.4) in DL tests involving non-forced and both right and left-forced attention. This study aims to investigate DL processing in adults with listening difficulties (LD). Previous studies have suggested that varying attention demands in dichotic listening (DL) tasks might be a clinically feasible method to distinguish ‘bottom-up’ from ‘top-down’ deficits in listening.
