However, equivalent systematic attempt in evaluating the possible correlations and consequences of specialization in reference to multiple psycho-cognitive aspects of the indi- vidual’s personality is not observable from the point of view of psychological science. Objective of the current study is the introduction of a theoretical model of specialization as a dynamic variable, as a trend, and from that stand point to evaluate a person’s specialization degree in relation to other parameters of its psycho-cognitive being. In order to test the validity of the conception of specialization as a measurable factor, the Specialization Questionnaire (S.Q.) is created and intro- duced. More specifically, the S.Q. is aiming, on the one hand, at quantifying the degree of profes- sional specialization and, on the other hand, at investigating the possible correlation between professional specialization and the tendency to seek for, respectively, specialized stimuli in other aspects of life, such as the personal-free time and the interpersonal relations.
