Some CI users can utilize timbre cues remarkably well when perceiving vocal emotions. Echoing previous research, we found that better vocal emotion perception was associated with better quality of life ratings. There was enormous variability between CI users, with low performers responding close to guessing level. Thus, under the conditions of this task, CIs were inefficient in conveying emotion based on F0 alone. Importantly, while NH individuals used timbre and fundamental frequency (F0) information to equivalent degrees, CI users were far more efficient in using timbre (compared to F0) information for this task. Unsurprisingly, CI users as a group showed lower performance in vocal emotion perception overall. Twenty-five CI users and 25 NH individuals (matched for age and gender) performed fearful-angry discriminations on bisyllabic pseudoword stimuli from morph continua across all acoustic parameters (Full), or across selected parameters (F0, Timbre, or Time information), with other parameters set to a noninformative intermediate level. We compared emotion perception in CI users and normal-hearing (NH) individuals, using parameter-specific voice morphing. Research on cochlear implants (CIs) has focused on speech comprehension, with little research on perception of vocal emotions. Future studies on larger cohort examining musical emotion perception and neurocognition is imperative to have deeper understanding of this debilitating condition. Limitations of study include small sample size and heterogeneity. There exists a significant relationship between music cognition and attention, which could be implicated in use of music interventions to ameliorate cognitive deficits. Individuals with mild-moderate MDD show significant deficits in working memory, verbal learning and memory, however, not in music cognition. Similarly, music cognition significantly predicted focused attention ( p < 0.01). Attention alone contributed to 62.1% of variance in music cognition. Focused attention and memory index predicted music cognition in HC and the combined group (MDD + HC) ( p < 0.01). Groups did not differ significantly in any of the indices - focused attention, executive function, learning and memory as well as on music cognition. Three indices were computed for a comprehensive evaluation. MDD group performed significantly lower than HC on working memory ( p = 0.007), verbal learning ( p = 0.02) and retention ( p = 0.03). Patients diagnosed with mild or moderate MDD ( n = 19) and matched healthy controls (HC) ( n = 18) were evaluated on selected tests from NIMHANS Neuropsychological test battery and Montreal battery for evaluation of amusia (MBEA). To examine musical and neuro-cognitive deficits in patients with mild-moderate MDD. With growing evidence on use of music based intervention to target cognitive deficits, it is imperative to explore nature of music cognitive ability in MDD. In MDD, large focus has been on evaluating emotion deficits and just a handful on music cognition. Recently, studies have explored music as cognitive ability in various clinical conditions. Studies have explored cognitive deficits in MDD, however, given inconsistent results, especially in mild-moderate MDD. Cognitive deficits are one of the core features of major depressive disorder (MDD) that play crucial role in functional recovery.
