ObjectivesThe study's main objective was to compare Listening Effort (LE) in children with central auditory processing disorder [(C)APD] and typically developing children in quiet and at −2 and −6 dB SNR conditions. And to determine the relationship between LE and auditory processing abilities in children with (C)APD. MethodsThe study included 30 children (15 typically developing children and 15 diagnosed with (C)APD) aged 10–12 years. LE was measured using a dual-tasking paradigm. The primary task required the child to repeat the words. The second task required the child to click the mouse based on the image displayed on the laptop's screen. The primary task was done at quiet, −2 dB SNR, and −6 dB SNR conditions. LE was correlated with dichotic CV, duration pattern test, speech perception in noise - Indian English, and gap detection test in children with (C)APD. ResultsA mixed ANOVA was performed with LE in various conditions as the within-subject factor and group as the between-subject factor for both repetition and reaction time. The study found that LE repetition and reaction time had a significant main effect across conditions and groups. The correlation results revealed a significant relationship between LE reaction time with dichotic scores and GDT thresholds only at −2 dB SNR and −6 dB SNR conditions. There was no significant correlation between other auditory processing abilities and LE under different conditions, such as quiet, SPIN-IE, and DPT at −2 dB SNR and −6 dB SNR. ConclusionThe study emphasizes the importance of cognitive abilities for adequate listening comprehension in challenging situations. As a result, assessing LE in this population may provide additional information for developing therapeutic activities and assisting the child in overcoming listening difficulties.
