Gene–environmental architecture of adolescent substance use
(Cambridge University Press, 2018-02-19)

Early warm-rewarding parenting moderates the genetic contributions to callous-unemotional traits in childhood
Warm-rewarding genetic callous-unemotional
Background Previous gene–environment interaction studies of CU traits have relied on the candidate gene approach, which does not account for the entire genetic load of complex phenotypes. Moreover, these studies have ...
Associations between daily mood states and brain gray matter volume, resting-state functional connectivity and task-based activity in healthy adults
(Frontiers Media, 2018-05-01)
Numerous studies have shown differences in the functioning in the areas of the frontal-limbic circuitry between depressed patients and controls. However, current knowledge on frontal-limbic neural substrates of individual ...
Using single-case designs in practical settings: Is replication always necessary?
Is within-subject replication always necessary?
Behavior analysts have widely adopted and embraced within-subject replication through the use of reversal and multielement designs. However, the withdrawal of treatment, which is central to these designs, may not be ...
