Abstract
Dyslexia is a language-based disorder that is mainly charac-
terized by di culties in reading and writing. The behavior of people with
dyslexia expresses itself by poor ability in discriminating letters, causing
reversal of letters, less accuracy and
uency while reading. Therefore,
this research will focus on the question whether people who su er from
dyslexia experience similarity of letters di erently than people without
dyslexia, based on perceived phonological and visual features. Moreover,
this research tries to detect if speci c features are decisive in distinguish-
ing dyslectic behavior. To measure the di erences in perceived similarity,
the multidimensional scaling inverse method was used. This method is
used, because it represents the mental representation of similarities be-
tween perceived objects by representing dissimilarity between objects as
a distance in space. The results of this research do not show any sig-
ni cant di erence between the two groups. Also, none of the examined
phonological or visual features form any indication for dyslexia. How-
ever, the study was limited due to the small amount of participants and
the di culty of the task. It therefore is not possible to draw any strong
conclusion from this research. Future research with a larger sample size
and a more accessible task is recommended.
