Behavioral inhibition (CI) is a temperamental variable that generates shyness, withdrawal, social avoidance, restlessness or social discomfort, as well as fear of unknown people, objects and / or situations (García-Coll, Kagan & Reznick, 1984).
The CI variable has been the object of study in considerable research during the last decades.
Specifically, since 2000, a large number of studies have focused on understanding the relationship between HF and psychopathology, the variables associated with inhibition, and the methods for evaluating it.
