Item Does Chronic Subjective Tinnitus Affect Cognitive Performance In Adults with Hearing Thresholds of 25 dB and Less Between 0.5-4 kHz(JOURNAL OF THE AMERICAN ACADEMY OF AUDIOLOGY, 2024) Deniz-Sakarya, Merve; Cinar-Satekin, Merve; Yaldiz, Zahide C. B.; Tokgoz-Yilmaz, SunaBackground In literature, the cognitive performance results of normal hearing individuals with tinnitus are inconsistent. It also differs in the control of other factors that may affect cognition. Purpose This study aimed to determine the differences in attention and memory performance between normal hearing individuals with chronic subjective tinnitus and age-sex-education-matched healthy controls. Study Sample Normal hearing individuals with subjective chronic tinnitus between 18 and 55 years of age, who have normal cognitive abilities (tinnitus group, n = 30) and age-sex-matched normal hearing individuals without tinnitus who have normal cognitive abilities (control group, n = 30) were included in this study. Data Collection The Montreal Cognitive Assessment Test measured participants' general cognitive screening, and depressive symptoms were measured by Beck Depression Inventory (BDI). Tinnitus Handicap Inventory was used to determine the tinnitus handicap levels. Attention performance was evaluated with Stroop Test-TBAG Form, and short-term and working memory performances were evaluated with the Wechsler Adult Intelligence Scale-Revised (WAIS-R)-Digit Span Test. Results The tinnitus and control groups' depressive symptom scores were similar concerning the BDI ( p = 0.90). There was no statistically significant difference between both groups according to the completion time of the five sections of the Stroop Test, the number of errors and corrections of the Stroop 5 test, and the (WAIS-R)-Digit Span Test scores ( p > 0.05). Conclusion In our study, the Stroop Test and Digit Span Test performances of individuals with tinnitus and normal hearing were similar to the control group. Despite previous studies claiming an effect of tinnitus on cognition, our contrary findings are discussed in the light of other demographic, audiological, and psychological measurement variables, especially hearing loss.Item Working Memory, Attention Skills, and Language Proficiency in Children with Unilateral and Bilateral Cochlear Implants(JOURNAL OF THE AMERICAN ACADEMY OF AUDIOLOGY, 2024) Dikderi, Cagla; Atak, Hilal B. Ozkan; Yucel, EsraBackground Previous studies observed that children with cochlear implants (CIs) have poor language, working memory, and attention skills. The ability to perform cognitive tasks, such as attention and memory, plays a crucial role in the academic achievement and everyday life of children with hearing impairment. Purpose This study aimed to evaluate and compare the effects of age at the time of implantation and bilateral hearing on cognitive skills, such as language development, working memory, and selective attention, among children with CIs. Research Design Language skills were assessed using the Test of Language Development-Primary: Fourth Edition (TOLD-P:4), working memory using the Visual-Aural Digit Span Test-Revised Form (VADS-R), and selective attention skills using the Stroop Test TBAG Form. Study Sample A total of 58 participants, comprised of 21 children with early unilateral CIs (before 2 years), 18 children with late unilateral CIs (after 2 years), and 19 children with bilateral CIs, between the ages of 6 and 9 years, were included in the study. Data Collection and Analysis According to the age at the time of implantation and whether or not the participant was unilaterally or bilaterally implanted, the mean scores, percentage values, and resultant scores of the participants were calculated using the Mann-Whitney U test. The number of repeated backward digit spans for the VADS-R test, completion times, number of errors and corrections for the Stroop test, raw scores, scaled scores corresponding to raw scores at the relevant age, descriptive terms for the TOLD-P:4 test, and within-group comparisons for all tests were examined. Results There were significant differences in language, working memory, and attention skills between individuals with early and late unilateral cochlear implantation, whereas there were no significant differences in many subtests between individuals with early unilateral and bilateral cochlear implantation. Conclusion These findings demonstrate the importance of early cochlear implantation and bilateral hearing on the development of cognitive processes, such as language development, selective attention, and memory skills, which are important factors that may contribute to children's academic performance and overall success.Item Multimodal Video Captioning Using Object-Auditory Information Fusion with Transformers(2023) Selbes, Berkay; Sert, MustafaVideo captioning aims to generate natural language sentences of an input video. Generating coherent natural language sentences is a challenging task due to the complex nature of video content such as object and scene understanding, extraction of object- and event-specific auditory information, and acquisition of relationships among objects. In this study, we address the problem of efficient modeling of object interactions in scenes, as they include crucial information regarding the events in the visual scene. To this end, we propose to use object features along with auditory information to better model the audio-visual scene appearing within the video. Specifically, we extract Faster R-CNN as the object features and VGGish as the auditory features and design a transformer encoder-decoder architecture in the multimodal setup. Experiments on MSR-VTT show encouraging results and object features better model the object interactions along with the auditory information in comparison to the ResNet features.
