In recent years, with the emergence of connectionism theory and the deepening of psycholinguistics, the research foundation of second language acquisition has been provided. This paper delves into the impact of learning frequency on the development of language sense in second language acquisition. It provides a brief overview of the relationship between learning frequency and second language acquisition. Additionally, it emphasizes the positive effects of learning frequency on the cultivation of language sense from three angles: efficiency of language sense acquisition, self-improvement of language sense, and cognitive processes and memory in the brain. The paper further substantiates these claims through comparative experiments that demonstrate the promotion effect of learning frequency on the cultivation of language sense in learners.
