a versatile preservative to limit the microbial growth and to control the taste in some food and beverage. However, it has been reported to cause a wide spectrum of severe adverse reactions. Therefore, it is important to determine the amount of sulfite in food and beverage to ensure consumer safety. An efficient electrocatalytic biosensor for sulfite detection was developed by immobilizing of human sulfite oxidase (hSO) on 3-aminoproplytriethoxysilane (APTES) modified indium tin oxide (ITO) electrode. Cyclic voltammetry was employed to investigate the electrochemical characteristics of the hSO modified ITO electrode for various pretreatment and binding conditions. Amperometry was also utilized to demonstrate the current responses of the sulfite sensor toward sodium sulfite in an aqueous solution at a potential of 0 V (vs. Ag/AgCl 1 M KCl). The proposed sulfite sensor has a linear range between 0.5 to 2 mM with a correlation coefficient 0.972. Then, the additional polymer layer of PVA was introduced to extend the linear range of sulfite sensor and protect the enzyme. The linear range of sulfite sensor with 5% coverage increases from 2.8 to 20 mM at a correlation coefficient of 0.983. In addition, the stability of sulfite sensor with 5% PVA coverage increases until 14 days when kept in 0.5 mM Tris-buffer, pH 7.0 at 4 8C. Therefore, this sensor could be applied for the detection of sulfite in the real sample, especially in food and beverage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sulfite%20oxidase" title="sulfite oxidase">sulfite oxidase</a>, <a href="https://publications.waset.org/abstracts/search?q=bioelectrocatalytsis" title=" bioelectrocatalytsis"> bioelectrocatalytsis</a>, <a href="https://publications.waset.org/abstracts/search?q=indium%20tin%20oxide" title=" indium tin oxide"> indium tin oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20electrochemistry" title=" direct electrochemistry"> direct electrochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfite%20sensor" title=" sulfite sensor"> sulfite sensor</a> </p> <a href="https://publications.waset.org/abstracts/67534/development-of-sulfite-biosensor-based-on-sulfite-oxidase-immobilized-on-3-aminoproplytriethoxysilane-modified-indium-tin-oxide-electrode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67534.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">231</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> CSR and Its Internal Communication – Effects on the Employee Commitment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silke%20Bustamante">Silke Bustamante</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Pelzeter"> Andrea Pelzeter</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Deckmann"> Andreas Deckmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Rudi%20Ehlscheidt"> Rudi Ehlscheidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Franziska%20Freudenberger"> Franziska Freudenberger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CSR is associated with a great number of positive effects. This also includes the positive impact of CSR on the commitment of its employees. The internal CSR communication here takes the essential function as a mediator of the CSR performance of a company to the employees. The importance of CSR communication is, therefore, essential. Employees can usually only perceive the CSR efforts of a company if it is also communicated to them. Only if the employees perceive the CSR of their employer positively, the employer-CSR can also have a positive impact on their affective commitment. Therefore, organizational and individual factors are crucial and thus need to consider. This relationship between the organizational and individual factors was investigated in a qualitative case study in six companies of the German service sector. Expert interviews and focus group interviews were conducted and questionnaire-based ratings by company representatives were raised. Among the individual factors, in terms of CSR, the expectations and relevance of its employees, as well as the perception of CSR by the staff, are included. The organizational factors include the actual CSR performance and its communication. Ultimately, the impact of CSR on the commitment is examined with this holistic approach. The results show that the individual CSR perception does not always match the corporate CSR performance and its depiction in internal communication. Furthermore, employees have given suggestions on how CSR should be communicated by their employer. Knowledge memory systems (e.g. wiki) on the on hand and media-based information, on the other hand, were highlighted. Primarily the employee-related CSR is most important for the employees, whereas ecological CSR activities hardly play a role. The findings indicate the importance of CSR communication in the CSR concept as it provides the missing link between CSR performance and appreciation by an increase in commitment. It should only be communicated, what is done. CSR communication should also be carried out in a plausible and transparent way. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CSR" title="CSR">CSR</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20commitment" title=" employee commitment"> employee commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=employer%20brand" title=" employer brand"> employer brand</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20communication" title=" internal communication"> internal communication</a> </p> <a href="https://publications.waset.org/abstracts/46336/csr-and-its-internal-communication-effects-on-the-employee-commitment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46336.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">265</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> CSR and Employer Attractiveness: The Relationship of Value Orientation of High-Potential Applicants and Their Decision for an Employer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silke%20Bustamante">Silke Bustamante</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Pelzeter"> Andrea Pelzeter</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Deckmann"> Andreas Deckmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Rudi%20Ehlscheidt"> Rudi Ehlscheidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Franziska%20Freudenberger"> Franziska Freudenberger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Against the background of demographic changes and the need for motivated and talented employees, companies have a growing interest in being perceived as an attractive employer and gain a competitive edge in the market for talents. Research indicates that corporate social responsibility plays an important role employer choice. This is assumed to be particularly true for the cohorts of the so-called generations y younger applicants born later. Several studies identified cultural, educational and generational differences in CSR preferences. However, until now literature that links preferences for employers’ responsibility with the individual value orientation of the job applicant is scarce. This paper seeks to close this gap and analyzes the preference structure of 500 German university graduates for CSR-related and non-CSR-related employer attributes contingent on their value orientation. In a first step, we identified 17 CSR related attributes in five CSR dimensions (ecology, community, workplace, governance, and market) as well as 11 traditional attributes such as salary, reputation, personal development etc. based on literature review and focus groups. We then used an adapted Conjoint Analysis framework in order to understand the relative preference of each attribute for each participant. Additionally, we surveyed the value orientation of participants based on the European Social Survey (ESS) 21-item human values scale that allow a differentiation of participants into clusters of value orientation. The results allow us not only to operationalize preferences for CSR and other important employer attributes, but – more importantly – to answer the question how different values structures play together with CSR preferences of potential employees. They hereby allow companies to customize employee directed messages to their respective target group and design their employer brand accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20social%20responsibility" title="corporate social responsibility">corporate social responsibility</a>, <a href="https://publications.waset.org/abstracts/search?q=employer%20attractiveness" title=" employer attractiveness"> employer attractiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=employer%20brand" title=" employer brand"> employer brand</a>, <a href="https://publications.waset.org/abstracts/search?q=recruiting" title=" recruiting"> recruiting</a>, <a href="https://publications.waset.org/abstracts/search?q=values" title=" values"> values</a> </p> <a href="https://publications.waset.org/abstracts/46339/csr-and-employer-attractiveness-the-relationship-of-value-orientation-of-high-potential-applicants-and-their-decision-for-an-employer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46339.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Decisional Regret in Men with Localized Prostate Cancer among Various Treatment Options and the Association with Erectile Functioning and Depressive Symptoms: A Moderation Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caren%20Hilger">Caren Hilger</a>, <a href="https://publications.waset.org/abstracts/search?q=Silke%20Burkert"> Silke Burkert</a>, <a href="https://publications.waset.org/abstracts/search?q=Friederike%20Kendel"> Friederike Kendel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Men with localized prostate cancer (PCa) have to choose among different treatment options, such as active surveillance (AS) and radical prostatectomy (RP). All available treatment options may be accompanied by specific psychological or physiological side effects. Depending on the nature and extent of these side effects, patients are more or less likely to be satisfied or to struggle with their treatment decision in the long term. Therefore, the aim of this study was to assess and explain decisional regret in men with localized PCa. The role of erectile functioning as one of the main physiological side effects of invasive PCa treatment, depressive symptoms as a common psychological side effect, and the association of erectile functioning and depressive symptoms with decisional regret were investigated. Men with localized PCa initially managed with AS or RP (N=292) were matched according to length of therapy (mean 47.9±15.4 months). Subjects completed mailed questionnaires assessing decisional regret, changes in erectile functioning, depressive symptoms, and sociodemographic variables. Clinical data were obtained from case report forms. Differences among the two treatment groups (AS and RP) were calculated using t-tests and χ²-tests, relationships of decisional regret with erectile functioning and depressive symptoms were computed using multiple regression. Men were on average 70±7.2 years old. The two treatment groups differed markedly regarding decisional regret (p<.001, d=.50), changes in erectile functioning (p<.001, d=1.2), and depressive symptoms (p=.01, d=.30), with men after RP reporting higher values, respectively. Regression analyses showed that after adjustment for age, tumor risk category, and changes in erectile functioning, depressive symptoms were still significantly associated with decisional regret (B=0.52, p<.001). Additionally, when predicting decisional regret, the interaction of changes in erectile functioning and depressive symptoms reached significance for men after RP (B=0.52, p<.001), but not for men under AS (B=-0.16, p=.14). With increased changes in erectile functioning, the association of depressive symptoms with decisional regret became stronger in men after RP. Decisional regret is a phenomenon more prominent in men after RP than in men under AS. Erectile functioning and depressive symptoms interact in their prediction of decisional regret. Screening and treating depressive symptoms might constitute a starting point for interventions aiming to reduce decisional regret in this target group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20surveillance" title="active surveillance">active surveillance</a>, <a href="https://publications.waset.org/abstracts/search?q=decisional%20regret" title=" decisional regret"> decisional regret</a>, <a href="https://publications.waset.org/abstracts/search?q=depressive%20symptoms" title=" depressive symptoms"> depressive symptoms</a>, <a href="https://publications.waset.org/abstracts/search?q=erectile%20functioning" title=" erectile functioning"> erectile functioning</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer" title=" prostate cancer"> prostate cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=radical%20prostatectomy" title=" radical prostatectomy"> radical prostatectomy</a> </p> <a href="https://publications.waset.org/abstracts/62967/decisional-regret-in-men-with-localized-prostate-cancer-among-various-treatment-options-and-the-association-with-erectile-functioning-and-depressive-symptoms-a-moderation-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62967.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">218</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> The Impact of CSR Satisfaction on Employee Commitment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silke%20Bustamante">Silke Bustamante</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Pelzeter"> Andrea Pelzeter</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Deckmann"> Andreas Deckmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Rudi%20Ehlscheidt"> Rudi Ehlscheidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Franziska%20Freudenberger"> Franziska Freudenberger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many companies increasingly seek to enhance their attractiveness as an employer to bind their employees. At the same time, corporate responsibility for social and ecological issues seems to become a more important part of an attractive employer brand. It enables the company to match the values and expectations of its members, to signal fairness towards them and to increase its brand potential for positive psychological identification on the employees’ side. In the last decade, several empirical studies have focused this relationship, confirming a positive effect of employees’ CSR perception and their affective organizational commitment. The current paper aims to take a slightly different view by analyzing the impact of another factor on commitment: the weighted employee’s satisfaction with the employer CSR. For that purpose, it is assumed that commitment levels are rather a result of the fulfillment or disappointment of expectations. Hence, instead of merely asking how CSR perception affects commitment, a more complex independent variable is taken into account: a weighted satisfaction construct that summarizes two different factors. Therefore, the individual level of commitment contingent on CSR is conceptualized as a function of two psychological processes: (1) the individual significance that an employee ascribes to specific employer attributes and (2) the individual satisfaction based on the fulfillment of expectation that rely on preceding perceptions of employer attributes. The results presented are based on a quantitative survey that was undertaken among employees of the German service sector. Conceptually a five-dimensional CSR construct (ecology, employees, marketplace, society and corporate governance) and a two-dimensional non-CSR construct (company and workplace) were applied to differentiate employer characteristics. (1) Respondents were asked to indicate the importance of different facets of CSR-related and non-CSR-related employer attributes. By means of a conjoint analysis, the relative importance of each employer attribute was calculated from the data. (2) In addition to this, participants stated their level of satisfaction with specific employer attributes. Both indications were merged to individually weighted satisfaction indexes on the seven-dimensional levels of employer characteristics. The affective organizational commitment of employees (dependent variable) was gathered by applying the established 15-items Organizational Commitment Questionnaire (OCQ). The findings related to the relationship between satisfaction and commitment will be presented. Furthermore, the question will be addressed, how important satisfaction with CSR is in relation to the satisfaction with other attributes of the company in the creation of commitment. Practical as well as scientific implications will be discussed especially with reference to previous results that focused on CSR perception as a commitment driver. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20social%20responsibility" title="corporate social responsibility">corporate social responsibility</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20commitment" title=" organizational commitment"> organizational commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20attitudes%2Fsatisfaction" title=" employee attitudes/satisfaction"> employee attitudes/satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20expectations" title=" employee expectations"> employee expectations</a>, <a href="https://publications.waset.org/abstracts/search?q=employer%20brand" title=" employer brand"> employer brand</a> </p> <a href="https://publications.waset.org/abstracts/46338/the-impact-of-csr-satisfaction-on-employee-commitment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46338.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">267</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Analysis of Superconducting and Optical Properties in Atomic Layer Deposition and Sputtered Thin Films for Next-Generation Single-Photon Detectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nidhi%20Choudhary">Nidhi Choudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Silke%20A.%20Peeters"> Silke A.

Hadfield</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Superconducting Nanowire Single Photon Detectors (SNSPDs) have become leading devices in quantum optics and photonics, known for their exceptional efficiency in detecting single photons from ultraviolet to mid-infrared wavelengths with minimal dark counts, low noise, and reduced timing jitter. Recent advancements in materials science focus attention on refractory metal thin films such as NbN and NbTiN to enhance the optical properties and superconducting performance of SNSPDs, opening the way for next-generation detectors. These films have been deposited by several different techniques, such as atomic layer deposition (ALD), plasma pro-advanced plasma processing (ASP) and magnetron sputtering. The fabrication flexibility of these films enables precise control over morphology, crystallinity, stoichiometry and optical properties, which is crucial for optimising the SNSPD performance. Hence, it is imperative to study the optical and superconducting properties of these materials across a wide range of wavelengths. This study provides a comprehensive analysis of the optical and superconducting properties of some important materials in this category (NbN, NbTiN) by different deposition methods. Using Variable angle ellipsometry spectroscopy (VASE), we measured the refractive index, extinction, and absorption coefficient across a wide wavelength range (200-1700 nm) to enhance light confinement for optical communication devices. The critical temperature and sheet resistance were measured using a four-probe method in a custom-built, cryogen-free cooling system with a Sumitomo RDK-101D cold head and CNA-11C compressor. Our results indicate that ALD-deposited NbN shows a higher refractive index and extinction coefficient in the near-infrared region (~1500 nm) than sputtered NbN of the same thickness. Further, the analysis of the optical properties of plasma pro-ASP deposited NbTiN was performed at different substrate bias voltages and different thicknesses. The analysis of substrate bias voltage indicates that the maximum value of the refractive index and extinction coefficient observed for the substrate biasing of 50-80 V across a substrate bias range of (0 V - 150 V). The optical properties of sputtered NbN films are also investigated in terms of the different substrate temperatures during deposition (100 °C-500 °C). We find the higher the substrate temperature during deposition, the higher the value of the refractive index and extinction coefficient has been observed. In all our superconducting thin films ALD-deposited NbN films possess the highest critical temperature (~12 K) compared to sputtered (~8 K) and plasma pro-ASP (~5 K). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20communication" title="optical communication">optical communication</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=superconductivity" title=" superconductivity"> superconductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20layer%20deposition%20%28ALD%29" title=" atomic layer deposition (ALD)"> atomic layer deposition (ALD)</a>, <a href="https://publications.waset.org/abstracts/search?q=niobium%20nitride%20%28NbN%29" title=" niobium nitride (NbN)"> niobium nitride (NbN)</a>, <a href="https://publications.waset.org/abstracts/search?q=niobium%20titanium%20nitride%20%28NbTiN%29" title=" niobium titanium nitride (NbTiN)"> niobium titanium nitride (NbTiN)</a>, <a href="https://publications.waset.org/abstracts/search?q=SNSPD" title=" SNSPD"> SNSPD</a>, <a href="https://publications.waset.org/abstracts/search?q=superconducting%20detector" title=" superconducting detector"> superconducting detector</a>, <a href="https://publications.waset.org/abstracts/search?q=photon-counting." title=" photon-counting."> photon-counting.</a> </p> <a href="https://publications.waset.org/abstracts/190213/analysis-of-superconducting-and-optical-properties-in-atomic-layer-deposition-and-sputtered-thin-films-for-next-generation-single-photon-detectors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190213.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">29</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Deficient Multisensory Integration with Concomitant Resting-State Connectivity in Adult Attention Deficit/Hyperactivity Disorder (ADHD)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Schulze">Marcel Schulze</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrem%20%20Aslan"> Behrem Aslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Silke%20%20Lux"> Silke Lux</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20%20Philipsen"> Alexandra Philipsen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Patients with Attention Deficit/Hyperactivity Disorder (ADHD) often report that they are being flooded by sensory impressions. Studies investigating sensory processing show hypersensitivity for sensory inputs across the senses in children and adults with ADHD. Especially the auditory modality is affected by deficient acoustical inhibition and modulation of signals. While studying unimodal signal-processing is relevant and well-suited in a controlled laboratory environment, everyday life situations occur multimodal. A complex interplay of the senses is necessary to form a unified percept. In order to achieve this, the unimodal sensory modalities are bound together in a process called multisensory integration (MI). In the current study we investigate MI in an adult ADHD sample using the McGurk-effect – a well-known illusion where incongruent speech like phonemes lead in case of successful integration to a new perceived phoneme via late top-down attentional allocation . In ADHD neuronal dysregulation at rest e.g., aberrant within or between network functional connectivity may also account for difficulties in integrating across the senses. Therefore, the current study includes resting-state functional connectivity to investigate a possible relation of deficient network connectivity and the ability of stimulus integration. Method: Twenty-five ADHD patients (6 females, age: 30.08 (SD:9,3) years) and twenty-four healthy controls (9 females; age: 26.88 (SD: 6.3) years) were recruited. MI was examined using the McGurk effect, where - in case of successful MI - incongruent speech-like phonemes between visual and auditory modality are leading to a perception of a new phoneme. Mann-Whitney-U test was applied to assess statistical differences between groups. Echo-planar imaging-resting-state functional MRI was acquired on a 3.0 Tesla Siemens Magnetom MR scanner. A seed-to-voxel analysis was realized using the CONN toolbox. Results: Susceptibility to McGurk was significantly lowered for ADHD patients (ADHDMdn:5.83%, ControlsMdn:44.2%, U= 160.5, p=0.022, r=-0.34). When ADHD patients integrated phonemes, reaction times were significantly longer (ADHDMdn:1260ms, ControlsMdn:582ms, U=41.0, p<.000, r= -0.56). In functional connectivity medio temporal gyrus (seed) was negatively associated with primary auditory cortex, inferior frontal gyrus, precentral gyrus, and fusiform gyrus. Conclusion: MI seems to be deficient for ADHD patients for stimuli that need top-down attentional allocation. This finding is supported by stronger functional connectivity from unimodal sensory areas to polymodal, MI convergence zones for complex stimuli in ADHD patients. <p
