In the study of Siguan Jr., (1994) as cited in Sonsona (2012)self-concept was also found significant on the choice of specializationof students.

The study you mentioned highlights the importance of self-concept in influencing students' choices regarding their specialization. Self-concept pertains to an individual's perception of themselves and significantly impacts their decision-making processes, particularly in academic and vocational contexts.

In educational settings, a positive self-concept can lead to greater motivation and confidence in pursuing specific areas of study. Students who believe in their capabilities are more likely to choose fields that align with their interests and skills, thus affecting their career trajectories. Conversely, a negative self-concept may result in self-doubt and limited exploration of potential specializations, potentially hindering academic and professional growth.

The citation of Siguan Jr. in Sonsona's work indicates that there is empirical evidence supporting the relationship between self-concept and specialization choices among students. This suggests that educational institutions could benefit from fostering positive self-concept among students to enhance their decision-making regarding specializations, which may lead to more fulfilling educational experiences and professional outcomes.
