Small pieces make the big picture: the etiology of the relationship between executive functions and personality traits.

ABSTRACT:

Background

This study primarily aimed to explore the etiology of the phenotypic relationships between personality traits and executive functions. We assessed common genetic and environmental sources of variance in these phenomena by examining different dimensions of the Five Factor Model (FFM) and executive function factors. An additional research question focused on whether specific facets within the FFM share a greater genetic overlap with executive functions compared to broader personality dimensions.

Methods

The NEO-PI-R, the Wisconsin Card Sorting Test, the Trail Making Test, and verbal fluency tests were applied to a sample of 468 twins from the Serbian Twin Advanced Registry (153 monozygotic twin pairs).
