The current positive, exploratory and pre experimental research aimed at setting the differences in the visual attention distribution of translators in lexical elements present in the Source Text (ST) and Target Text (TT) with high and low specialized-language considering the time pressure variable. In order to achieve this purpose, two texts were presented to five subjects, who should read in order to comprehend. One of the texts with high-specialized language, while the other one with low-specialized language, both of them from the medicine area. Data was collected through the Eye-Tracker instrument, as well as a Likert scale questionnaire. The results obtained showed that participants’ visual attention distribution was focused on the terminological units of the texts; also, it was noticed that visual attention distribution was not significantly affected by time pressure, however, it was altered by the language specialization of the text. It was observed that the amount of time and the number of eye fixations were greater in the high–specialized language text in contrast to the low–specialized language text. Additionally, it was perceived that time pressure by itself did not affect in a significant way the development of the tasks, but it did affect participants’ mood when it was combined with a high- specialized language text.
