Naming images in aphasia: effects of illustrative and photographic images on naming performance in people with and without aphasia

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).
E-Inclusion – Defining Basic Image Properties for Illustrated Stimuli in Aphasia Treatment
2019-12, Reymond, Claire, Müller, Christine, Grumbinaite, Indre
Word production is stimulated by images in treatment processes for people with aphasia (Heuer & Hallowell, 2007). Although stimulation through pictorial stimuli has a long tradition in aphasia therapy, there is a lack in research on which image stimuli are the most suitable for this purpose (Brown & Thiessen, 2018). Current research assumes that stimulation via photographic images evokes better and more direct retrieve of searched words, than stimulation by illustrations (Heuer, 2016). However, the illustrations investigated so far mostly comprise black and white line drawings and there are hardy no studies investigating possible effects of different image parameters as style, image cropping or perspective in relation to clear naming. We developed a visual concept of illustrated images enabling clear determinability of activities and objects. The 128 designed stimuli that meet linguistic research criteria were named by 62 students regarding "name agreement" and evaluated on a 5-point scale with respect to "visual complexity" and "image agreement". The illustrated images will be examined in a following study regarding the correctness of the naming by persons with aphasia and be compared with corresponding photographic stimuli. The analysis presented here is part of the study E-Inclusion, an interdisciplinary project that includes researchers in life science technology, linguistics and speech therapy as well as image research from the University of Applied Sciences and Art Northwestern Switzerland (FHNW).
