Resumen: The different theories about personality traits have progressively evolved. There is, however, a general agreement on the considerable barriers that shyness behaviors can pose to well-being and personal development. Under the paradigm of quantitative research, the present study aims to analyze behaviors related to shyness in a sample of 391 people aged between 11 and 63 years. A questionnaire was used in which the frequency with which different behaviors appeared was estimated. The results have evidenced a more frequent presence of shy behaviors in the female sex. Considering different age groups, significant differences have also been found in certain specific behaviors. These findings have important implications since the prolonged time of pronounced shyness could lead to the appearance of more serious psychological disorders. In response to the avoidance of these psychological consequences, it is proposed that emotional and social competencies be assessed by the educational guidance teams as the main triggers that can affect the comprehensive development of students. In addition, it would be advisable to include in their educational centers different strategies or socio-emotional education programs that contribute to the personal, social, and emotional development of all students in all educational stages.
