25 Years of Molecular Psychology: The best is yet to come

Abstract

This editorial defines the scope of the field of Molecular Psychology, which refers to the study of behavior and its underlying neural systems using the toolset of molecular biology, particularly molecular genetics and epigenetics. It is related to other well-established fields that use molecular tools in animal model organisms (Behavioral Neuroscience; Neuroethology) or that focus on molecular mechanisms of human mental health and disease (Molecular Psychiatry; Health Psychology), but extends beyond these fields by its inclusion of broad domains of human behavior; the precise molecular mechanisms by which environmental exposure and experiences modify gene expression; and the ethical, legal, and social implications (ELSI) of these discoveries. Considering the first 25 years of studies that included candidate gene and genome-wide association studies, I suggest a roadmap for the next decade of work. On the launch of F1000 Molecular Psychology: Brain, Behavior & Society, I hope this publication platform will become instrumental in growing this field by promoting a spirit of support and community among its practitioners, embracing transparency and rigor, and publishing novel ideas and studies ranging from pilot and proof-of-concept first steps to gold-standard definitive milestones.
