As a result of globalization and the intensification of migration

processes, the number of bilingual and multilingual individuals is

rapidly increasing. This situation has made the study of

psycholinguistic features of code-switching in bilingual individuals an

urgent task in linguistics, psycholinguistics, and cognitive

psychology. The purpose of this study is to determine the general state,

development dynamics, and main trends of scientific research on the

cognitive and psycholinguistic aspects of code-switching in bilingual

individuals between 2002-2025 using bibliometric methods. In the

study, a total of 384 articles were selected from the ScienceDirect

scientific database using the keywords “code-switching,” “bilingual,”

and “switching costs.” These were analyzed using Excel software in

terms of years, publication types, methods used, geographical

distribution, and leading journals. The results revealed a sharp

increase in research in this field since 2019, with the majority of

studies conducted in the USA, China, and European countries. The

most active journals were found to be the “Journal of Pragmatics” and

“Language & Communication.” This analysis will serve as an

important resource for future researchers studying code-switching,

helping to guide research directions and identify existing gaps in the

field.
