Sažetak
Eye-tracking is a methodology that is slowly becoming more and more recognised in the field of speech and language pathology (SLP) as a valuable tool for diagnostic and clinical procedures. As a diagnostic instrument it can be used e.g. to complete and round the process of differentiation of children with dyslexia or specific language impairment from typically developing children and also among themselves. Additionally, it can be used in clinical purposes to e.g. monitor improvement in reading and understanding language resulting from the consistent and systematic speech and language therapy. In order to examine its usefulness in SLP, this pilot study was conducted. The main aim was to compare the reading proficiency of a second-grade child with language impairment (LI) and a second-grade child without LI. It was intended to test if the participants differ in the following variables: total reading time, number of fixations, saccades and regressions and total fixation duration. Two eye-tracking devices were used: a) one stationary ; SMI Hi- Speed View 500 and b) one mobile ; SMI-Red-M system. Moreover, the texts used varied in fonts: a) one dyslexia friendly font and b) one complex font, and in the linguistic complexity, one including a) mostly simple sentences and the other including also some b) compound and complex sentences. The analysis was exclusively based on descriptive statistical methods considering the number of participants included in the study. The results confirm the well- known findings that children with LI read more slowly, have more fixations and regressions and a longer fixation duration. Furthermore, they indicate that fonts and text complexity influence more significantly on the overall reading proficiency for a child with LI than for the typically developing child. Both children prefer the mobile apparatus because it allows them not to be so strictly fixated, but it is open to question if the devices are equally reliable. Bearing all this in mind, new questions arise and are to be discussed during author’s presentation at CLEAR workshop: what is the best sitting position for the assessment of children, which measures are best to be taken and are most informative for the reading paradigm, should the SLPs conducting a research or using eye-tracking in clinical settings additionally adjust the text stimuli for the participants with LI (e.g. font, text alignment, text complexity, background colours, …), how to handle data etc. It is the author’s intention to accept new discoveries and conclusions and to incorporate them in larger studies of language processing and reading including participants with LI.
