The article examines the impact of artificial intelligence (AI) technologies on the cognitive development of modern students. It analyzes changes in areas such as attention, memory, thinking, and perception that emerge with the active use of AI in educational environments. Special focus is given to positive effects (personalization of learning, increased information processing speed, expanded self-education opportunities) and potential risks (decline in critical thinking, dependence on digital technologies, reduced depth of information processing). The results of theoretical and empirical analysis are presented, offering insights into the prospects of AI integration into education from the perspective of students' cognitive development.

As the research subjects, first- and second-year students aged 18–20 were selected and divided into experimental and control groups. Informed consent for participation in the study was obtained from all participants. During the study, diagnostic and formative experiments were conducted. In the formative stage, significant changes in cognitive processes were observed among students after they used ChatGPT for three months. The research results demonstrated the notable impact of artificial intelligence tools on students' cognitive processes: on one hand, improvements were noted in skills related to comprehending scientific texts and identifying key ideas, while on the other hand, a decline was observed in attention stability and focus, as well as in working memory speed and reasoning ability. The obtained data support this scientific hypothesis
