to better capture the trait of interest. Interestingly, previous studies [23, 24] found a relation between GABRA2 and adults’ NEO-Impulsiveness, which reflects impulsivity under negative affectivity. Nonetheless, because few studies have shown an association between GABRA2 variation and impulsive behavior characterized specifically by a lack of planfulness and cognitive control, this association should be considered as preliminary until replicated in other studies.
