Summary

The observational study aims to investigate the effect of two factors that influence the ease with which aphasic and healthy participants name visual stimuli. The main factors investigated here are the image type of the visual stimulus (drawing or photographic image) and the response variety (standard language vs dialect). The hypothesis is formulated as follows: The image type of the visual stimulus (drawing or photographic image) and the response variety (standard language or dialect) will have an effect on naming correctness and/or naming latencies in people with aphasia within the picture naming test.

The experiment was as follows: Persons with aphasia and healthy participants were presented with objects and verbs depicted as photographs or illustrations on a tablet. All participants were asked to name the depicted term in two different language varieties as correctly and as fast as possible. Answers were recorded synchronously. No feedback should be given to the participants (=no therapy). The results of picture naming were not analyzed patient-specifically in relation to their condition or therapy. Naming performance was collected as a momentary data set in order to investigate the speed of naming in general.

The ethic committee Northwestern and Central Switzerland approved the study to be observational as no effect of intervention(s) on biomedical or other health related outcomes were evaluated, but only the influence of type of the visual stimulus and the response variety on correctness and naming latencies in the two participant groups.
