- PublikationNaming images in aphasia: effects of illustrative and photographic images on naming performance in people with and without aphasia(Taylor & Francis, 03.05.2022) Reymond, Claire; Widmer Beierlein, Sandra; Müller, Christine; Kuntner, Katrin Petra; Falcón García, Noelia; Grumbinaite, Indre; Hemm-Ode, Simone; Degen, Markus; Parrillo, Fabrizio; Karlin, Stefan; Park, Sung Hea; Blechschmidt, Anja; Reutimann, Ricarda [in: Aphasiology]Background: Picture naming is a common tool in aphasia diagnosis and therapy. However, opin-ions differ as to which type of image (e.g., photographs, drawings) is most suitable for naming tasks and whether there is a difference on naming correctness and latencies based on image type. Moreover, recent studies have mainly analysed colour photographs and black-and-white line drawings leaving out image types like graphic representations that apply image features that can facilitate naming such as colour, controlled size, or texture. Aims: To shed more light on ap-propriate image types for persons with aphasia, we created graphic representations depicting nouns and verbs and compared them to photographic stimuli in a naming task including persons with aphasia (PWA) and a control group (CG). Methods & Procedures: 33 PWA and 33 age matched persons (CG) participated in the study. Naming correctness and latencies were meas-ured in two different conditions: concepts depicted as coloured photographs vs. as graphic rep-resentations. 128 pictures of linguistically controlled German-language concepts (64 nouns, 64 verbs) had to be named. The designed graphic stimuli were developed by professional designers based on photographs. The photographs were selected from stock image databases according to a defined image concept. This image concept was based on empirical findings regarding im-age features that facilitate naming (e.g., colour, texture, shading) and was applied to the selec-tion of the photographs as well as to the creation of the graphic representations. The images were presented in pseudo-randomized sequences on a tablet and all reactions of the participants were videotaped. The data from the main study was analysed using generalized linear mixed models (GLMM) and linear mixed models (LMM).01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationErratum to “Lamb waves and adaptive beamforming for aberration correction in medical ultrasound imaging”(IEEE, 02/2021) Mozaffarzadeh, Moein; Minonzio, Claudio; De jong, Nico; Verweij, Martin; Hemm-Ode, Simone; Renaud, Guillaume; Daeichin, Verya [in: IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control]In the above article [1] , we mentioned that the superposition of the different symmetric (S) modes in the frequency wavenumber (f-k) domain results in a high-intensity region where its slope corresponds to the longitudinal wave speed in the slab. However, we have recently understood that this high intensity region belongs to the propagation of a wave called lateral wave or head wave [2] – [5] . It is generated if the longitudinal sound speed of the aberrator (i.e., the PVC slab) is larger than that of water and if the incident wavefront is curved. When the incidence angle at the interface between water and PVC is near the critical angle, the refracted wave in PVC reradiates a small part of its energy into the fluid (i.e., the head wave). As discussed in [4] , if the thickness of the waveguide is larger than the wavelength, the first arriving signal is the head wave. This is also the case in our study [1] where the ultrasound wavelength of a compressional wave in PVC was close to 1 mm, and a PVC slab with a thickness of 8 mm was used.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationE-Inclusion – Ein interdisziplinäres, Schweizerisches Aphasie-Forschungsprojekt(Aphasie Suisse, 2021) Widmer Beierlein, Sandra; Reymond, Claire; Kuntner, Katrin Petra; Blechschmidt, Anja; Degen, Markus; Müller, Christine; Falcón García, Noelia; Altermatt, Sven; Elsener, Claudia; Karlin, Stefan; Park, Sung Hea; Reutimann, Ricarda; Parrillo, Fabrizio; Bucheli, Sandra; Grumbinaite, Indre; Jochmann, Angela; Harvey, Morgaine; Lee, Jingyu; Loew, Joelle; Meier, Lena; Poffet, Laurent; Renner, Michael; Schiltknecht, Sarah; Shah, Ashesh; Schneider, Gerold; Strub, Alisa; Trachsel, Karen; Winkler, Manon; Wyss, Sandra; Hemm-Ode, Simone [in: Aphasie und verwandte Gebiete]«E-Inclusion» ist ein interdisziplinäres, schweizerisches Aphasie-Forschungsprojekt mit dem Ziel einen App-Prototypen für die Benenntherapie zu entwickeln. Dazu wurden wissenschaftliche Fragestellungen zu den drei Themengebieten «Bildart», «Sprachvarietät » und «neue Technologien» in zwei Hauptstudien und fünf ergänzenden Studien untersucht. In der Hauptstudie 1 wurde bei niederfrequenten Nomen und Verben in einer Benennstudie mit Menschen mit einer Aphasie und einer Kontrollgruppe getestet, ob die Bildart (Fotografie vs. Illustration) und die Sprachvarietät (Dialekt vs. Hochdeutsch) die Benennleistung beeinflussen. In der Hauptstudie 2 wurde die mündliche Benennreaktion auf Nomen aus dem AAT (Aachener Aphasie Test) von Menschen mit Aphasie auf Wortebene gemessen, um Veränderungen beispielsweise in der Benennlatenz objektiv aufgrund akustischer Parameter messbar zu machen. Die ergänzenden Studien dienten der Überprüfung des Materials in Bezug auf das schriftliche und mündliche «Name Agreement». Ausserdem wurden Daten zu sog. subjektiven Frequenzen erhoben, um beispielsweise logopädisches Therapie- und Diagnostikmaterial in der Schweiz besser psycholinguistisch kontrollieren zu können. Eine weitere Studie widmete sich der Einschätzung von Sprachkenntnissen im Dialekt und Hochdeutschen sowie dem Gebrauch der Varietäten in verschiedenen Kontexten und Modalitäten. Die Ergebnisse dieser Studien wurden in einer Prototypen-App zusammengeführt.01B - Beitrag in Magazin oder Zeitung
