Moreover, it would be beneficial to consider behavioral measures that may be useful intermediate phenotypes between personality and neurological functioning. As previously noted, significant neurodevelopment of the prefrontal cortex occurs during emerging and early adulthood and may contribute to changes in both problematic alcohol involvement and personality. Miyake et al. (2000) conducted factor analyses on behavioral measures of executive functioning and identified specific subtypes of this construct, including facets related to impulsivity. Future research should consider incorporating behavioral measures when examining personality change and related constructs.
