Gene-environment interactions across development: Exploring DRD2 genotype and prenatal smoking effects on self-regulation.

Genetic factors dynamically interact with both pre- and postnatal environmental influences to shape development. Considerable attention has been devoted to gene-environment interactions (G x E) on important outcomes (A. Caspi & T.

Dopamine receptor (DRD2) genotype-dependent effects of nicotine on attention and distraction during rapid visual information processing.

The effects of nicotine, distractor type, and dopamine type-2 receptor (DRD2) genotype on rapid visual information processing (RVIP) task performance were assessed in habitual smokers. Four RVIP tasks differed in terms of distractor location (central vs. peripheral) and distractor type (numeric vs.
