Overview

Stephen J. Suomi is affiliated with the National Institutes of Health in the United States. Their research primarily focuses on psychology, with a total of 24 publications categorized under this main field of study. Within psychology, they have contributed extensively to subfields such as social psychology, clinical psychology, experimental and cognitive psychology, developmental and educational psychology, and cellular and molecular neuroscience.

Suomi's work covers a range of topics including neuroendocrine regulation and behavior, child and adolescent psychosocial and emotional development, evolutionary psychology and human behavior, child and animal learning development, primate behavior and ecology, stress responses and cortisol, and birth, development, and health. These thematic areas illustrate a broad and interdisciplinary approach to understanding behavior and development from both biological and psychological perspectives.

The scientist has published articles in various academic journals, with frequent appearances in Developmental Psychobiology, Neuropsychopharmacology, American Journal of Primatology, Journal of the American Academy of Child & Adolescent Psychiatry, and Hormones and Behavior. This distribution highlights a sustained engagement with both developmental and neuropharmacological aspects of behavior in nonhuman primates and related models.

Recent papers by Stephen J. Suomi include:

  • Intergenerational effects of mother's early rearing experience on offspring treatment and socioemotional development, 2020, Developmental Psychobiology
  • Clitoral length in immature and mature captive tufted capuchin (Sapajus spp.) females: A cross-sectional study, 2020, American Journal of Primatology
  • A nonhuman primate model of human non-suicidal self-injury: serotonin-transporter genotype-mediated typologies, 2021, Neuropsychopharmacology
