The development of technology is happening faster and faster, and the devices we used 10 years ago are already outdated. With the sudden development of technology, everyday life is changing, and it requires more and more flexibility and adaptability. Therefore, technology enters all aspects of human development and affects them positively or negatively. Regardless of the usefulness or harm of technology on human development, we spend more and more time in front of various devices with screens. As a result, children start to be handy and resourceful with mobile phones and tablets earlier because they use them from an earlier age. It is precisely because of this phenomenon that discussions about the impact of technology on language development have recently gained momentum. Lexical development begins with the appearance of the first word, and in the first three years of life language development is very intensive. With the onset of the vocabulary spurt around 18 months of life, children rapidly increase their vocabulary because of mapping and associating objects and actions with words. At the age of 3 to 4, children have acquired the basics of their mother tongue. Considering the increasing time of exposure to devices with screens, the purpose of this research was to examine the correlation between time spent in front of screens on vocabulary development of toddlers. The participants were 52 parents of toddlers. Data on the amount of time of being exposed to screens were obtained from the Screen Devices Usage Questionnaire (2021) and data on the vocabulary development of boys and girls were obtained from Croatian version of the MacArthur-Bates Communicative Development Inventory (CDI-III) (KORALJE – III; Kuvač Kraljević i Matić Škorić, in preparation). The results showed that there is no statistically significant correlation between the time a child spends in front of the screen during the weekday and weekend and the total number of words in the dictionary and in the specific categories nutrition, body, cognition and emotional state. Also, no statistically significant difference was obtained between boys and girls in vocabulary development with regard to exposure to screens. The interpretation of the results should be approached with caution and the limitations of the research should be taken into account.
