The Cognitive Information Processing Theory emphasizes that career decision-making is viewed from the perspective of information processing, which means the key to improve the job-seeker's ability of career choice is the connotation from accurate "cognition" to career choice. By studying the basic state of college students' career decision-making, through factor analysis, the factors creating college students' career decision-making difficulties are condensed into three aspects: "inadequate preparation", "lack of information" and "emotional factors". Countermeasures are put forward from three aspects: the knowledge domain, the decision-making skill domain, and the execution processing domain.
