abstract = {Background: Cognition is marked by complex cognitive
processes and can be quantifiedusing intelligence
constructs. On the other hand, affect is an indistinct
construct,seemingly happening subconsciously and difficult
to quantify (Newell $\&$ Shanks, 2014;Tamietto $\&$ de
Gelder, 2010). A large body of evidence has shown that
cognition isheritable and relates to brain structure (Devlin
et al., 1997; Krapohl et al., 2014). Indeed,studies have
shown that co-variation of cognition and brain structure is
driven by sharedadditive genetic effects (Toga $\&$
Thompson, 2005). Contrary to this, little is known aboutthe
genetic basis of affective behavior. The current study
investigates how cognition hasa phenotypic and genetic
correlation with emotion processing, and positive and
negativeaffect, and whether these aptitudes relate to
similar brain regions.Methods: Using a large sample of
healthy individuals based on the open access twindesignof
the Human Connectome Project, phenotypic correlation and
heritability and coheritabilityof cognitive abilities,
emotion processing, and positive and negative affectwere
tested using SOLAR-Eclipse. Following, these aptitudes were
correlated to corticalthickness, using a 200 parcel-based
approach (Schaefer et al., 2018) to summarizeindividual
differences in grey-matter structure in the cortex. Last,
the genetic correlationbetween total cognitive score,
emotion processing, and positive and negative affect on
onehand, and cortical thickness on the other was
assessed.Results: Behaviorally, a positive phenotypic
correlation of cognitive abilities with bothsuccessful
emotion processing and positive affect was observed. The
positive correlationbetween cognitive abilities and emotion
processing was shown to be driven by additivegenetic
effects. At the brain level, phenotypic and genetic
correlation between cognitionand affect was strongest in the
dorsolateral prefrontal cortex. Positive affect
additionallyshowed phenotypic correlation in occipital and
parietal lobe. In sum, this study pointstoward a shared
genetic basis of cognition and affect, anchored in the
dorsolateralprefrontal cortex.},
