  1. The Quality of Informed Consent: Mapping the Landscape. A Review of Empirical Data From Developing and Developed Countries.Amulya Mandava, Christine Pace, Benjamin Campbell, Ezekiel Emanuel & Christine Grady - 2012 - Journal of Medical Ethics 38 (6):356-365.
    Objective Some researchers claim that the quality of informed consent of clinical research participants in developing countries is worse than in developed countries. To evaluate this assumption, we reviewed the available data on the quality of consent in both settings. Methods We conducted a comprehensive PubMed search, examined bibliographies and literature reviews, and consulted with international experts on informed consent in order to identify studies published from 1966 to 2010 that used quantitative methods, surveyed participants or parents of paediatric participants (...)

    Adrenarche and Middle Childhood.Benjamin C. Campbell - 2011 - Human Nature 22 (3):327-349.
    Middle childhood, the period from 6 to 12 years of age, is defined socially by increasing autonomy and emotional regulation, somatically by the development of anatomical structures for subsistence, and endocrinologically by adrenarche, the adrenal production of dehydroepiandrosterone (DHEA). Here I suggest that DHEA plays a key role in the coordinated development of the brain and body beginning with middle childhood, via energetic allocation. I argue that with adrenarche, increasing levels of circulating DHEA act to down-regulate the release of glucose (...)

    Stress and Age at Menarche of Mothers and Daughters.Benjamin C. Campbell & J. Richard Udry - 1995 - Journal of Biosocial Science 27 (2):127-134.
    SummaryThe hypothesis that psychological stress during early childhood leads to advanced reproductive maturation was assessed using data from the California Childhood Health and Development Study. Regression analyses failed to indicate that bed wetting, nightmares or thumb-sucking at age 5 predict age at menarche, regardless of controls for mother's age at menarche. Among socioeconomic variables suggested as contextual stressors measured at age 9–11 only mother's education was a significant predictor of daughter's age at menarche, though its effect is trivial compared to (...)

    Evolutionary and Ecological Aspects of Early Brain Malnutrition in Humans.William D. Lukas & Benjamin C. Campbell - 2000 - Human Nature 11 (1):1-26.
    This article reviews the effects of malnutrition on early brain development using data generated from animal experiments and human clinical studies. Three related processes, each with their own functional consequences, are implicated in the alteration of brain development. (1) Maternal undernutrition at the start of pregnancy results in reduced transfer of nutrients across the placenta, allowing the conservation of effort for future reproductive episodes. (2) Differential allocation to growing organs by the fetus in response to nutritional stress spares the brain (...)
