The aim of the current paper was to identify the multidimensional conceptual integration of university students, and the differences in it according to the variable of gender, academic specialization and stage of study, and the research sample consisted of (400) students of Wasit University for morning preliminary studies, and for the scientific and humanitarian specialization, and the first and fourth stages were selected by random class equal method, and to achieve the objectives of the research, the researcher has built a multidimensional conceptual integration test by two parts, one of which is called (verbal conceptual integration), The other is called (conceptual formal merging), adopting the theory of conceptual integration of both (Faucónier and Turner, 2003), and after the researcher extracted the descriptive properties of the test, she applied it to the members of the research sample, and after collecting the data and processing them statistically using the statistical bag spss, it became clear through the results of the research that the university students have a weak ability in conceptual integration in both dimensions (verbal and formal), The results also indicated that there were no statistically significant differences in conceptual integration that could be attributed to both the gender variable and the school stage, while there were significant differences depending on the variable of the study specialization and in favor of the scientific specialization, and in the light of the results and conclusions of the current research, the researcher made a number of recommendations and suggestions.
