Beyond Co-Regulation: Interplay as a Methodological Framework for Examining Self-Regulation in Generative AI-Assisted Writing
As generative artificial intelligence (GenAI) tools become embedded in writing practices, researchers must refine methodologies for studying self-regulation in AI-assisted composition. While sociocognitive and co-regulation frameworks have effectively captured self-regulatory processes in human collaboration, they are insufficient for understanding how writers manage the dynamic and probabilistic nature of AI-generated text. This article introduc…
Long panel studies of small-scale rural societies in the Global South: What is their value, why are they rare, and suggestions to make them happen
Many topics in the behavioral sciences and epidemiology require researchers to directly observe entities (e.g., individuals, households) over a long time to identify lasting effects. Long-term panel data collection is more common in high-income countries than in small-scale rural societies (SSRS) of low-income countries. SSRS are mobile, nature-dependent, linguistic minorities, and highly autarkic. Analyzing such data using a life-course perspect…
Adult knowledge of wild plants associated with limited delayed health and nutritional benefits for children or adults in the face of external change: A yearly panel (2003−2010) study among Tsimane’, a…
Cross-sectional studies suggest that local ecological knowledge (LEK) helps humans cope with their environment. Among the forms of LEK, adult knowledge of wild plants has been associated with better child and adult health. We assess if the concurrent links between i) LEK and ii) health and nutritional status last and examine if LEK yields delayed benefits when societies face large socioeconomic and environmental changes. We use a yearly panel (20…
Changes in adult well-being and economic inequalities: An exploratory observational longitudinal study (2002–2010) of micro-level trends among Tsimane’, a small-scale rural society of Indigenous Peopl…
Knowing what happens over time to the lifeways of people in contemporary small-scale non-industrial societies of the rural Global South matters because it helps assess changes in the quality of life of underrepresented groups. It has been hard to answer the question because longitudinal information is rarely collected in such settings. A longitudinal dataset of nine years (2002–2010) from a horticultural-foraging society of Indigenous People in t…
Biocultural Strategies for Measuring Psychosocial Stress Outcomes in Field-based Research
The goal of assessing psychosocial stress as a process and outcome in naturalistic (i.e., field) settings is applicable across the social, biological, and health sciences. Meaningful measurement of biology-in-context is, however, far from simple or straightforward. In this brief methods review, we introduce theoretical framings, methodological conventions, and ethical concerns around field-collection of markers of psychosocial stress that have em…
Birth seasons and heights among girls and boys below 12 years of age: Lasting effects and catch-up growth among native Amazonians in Bolivia
The results suggest that redressing stunting will require attention to conditions in utero, infancy and late childhood

Water from fruit or the river? Examining hydration strategies and gastrointestinal illness among Tsimane’ adults in the Bolivian Amazon
Objective Water is an essential nutrient overlooked in many cross-cultural studies of human nutrition. The present article describes dietary water intake patterns among forager-horticulturalist adults in lowland Bolivia, compares daily intake with international references and examines if variation in how people acquire water relates to gastrointestinal illness. Design Cross-sectional observational study used survey, anthropometric and qualitative…

The consequences of linear growth stunting: Influence on body composition among youth in the bolivian amazon
Stunting, or linear growth retardation, has been documented in up to half of all children in rural indigenous populations of South America. Stunting is well understood as a signal of adverse conditions during growth, and has been associated with developmentally induced modifications to body composition, including body fat and muscularity, that stem from early growth restriction. This article examines the relation between short stature and three a…
Health and disease: Exploring the relation between parasitic infections, child nutrition status, and markets
Research in bioarchaeology and among living people provides insight into the biological and biocultural consequences of subsistence, political, and economic transitions. Central to this effort is examining infectious disease, such as diarrheal disease, respiratory infections, and parasitic infections because they are an important source of nutritional and energetic stress in both past and current groups. Although infection may not always result i…
Precursors to overnutrition: The effects of household market food expenditures on measures of body composition among Tsimane' adults in lowland Bolivia
Diurnal cortisol rhythms and child growth: Exploring the life history consequences of HPA activation among the Tsimane
OBJECTIVE: Although psychosocial stress has also been implicated as a contributor to growth failure by imposing energetic constraints during development, the direct physiological pathways by which these life history trade-offs are imposed are not well understood. This study explores associations between diurnal cortisol rhythms and differential patterns of linear child growth among the Tsimane, a horticulturalist and foraging society in the Boliv…

Short but catching up: Statural growth among native Amazonian Bolivian children
The ubiquity and consequences of childhood growth stunting ( Z score, HAZ) in rural areas of low‐income nations has galvanized research into the reversibility of stunting, but the shortage of panel data has hindered progress. Using panel data from a native Amazonian society of foragers‐farmers in Bolivia (Tsimane'), we estimate rates of catch‐up growth for stunted children. One hundred forty‐six girls and 158 boys 2 ≤ age ≤ 7 were measured annual…
Cultural Consonance and Psychological Well-Being. Estimates Using Longitudinal Data from an Amazonian Society
Cultural consonance and body morphology: Estimates with longitudinal data from an Amazonian society
Researchers have hypothesized that the degree to which an individual's actual behavior approximates the culturally valued lifestyle encoded in the dominant cultural model has consequences for physical and mental health. We contribute to this line of research by analyzing data from a longitudinal study composed of five annual surveys (2002–2006 inclusive) from 791 adults in one society of foragers–farmers in the Bolivian Amazon, the Tsimane'. We e…
Does civilization cause discontentment among indigenous Amazonians? Test of empirical data from the Tsimane' of Bolivia
Individual Wealth Rank, Community Wealth Inequality, and Self-Reported Adult Poor Health: A Test of Hypotheses with Panel Data (2002-2006) from Native Amazonians, Bolivia
Growing evidence suggests that economic inequality in a community harms the health of a person. Using panel data from a small-scale, preindustrial rural society, we test whether individual wealth rank and village wealth inequality affects self-reported poor health in a foraging-farming native Amazonian society. A person's wealth rank was negatively but weakly associated with self-reported morbidity. Each step up/year in the village wealth hierarc…
Cultural transmission of ethnobotanical knowledge and skills: An empirical analysis from an Amerindian society
Why no adult stunting penalty or height premium
Concepts and Methods in Studies Measuring Individual Ethnobotanical Knowledge
We review 34 quantitative studies that have measured individual-level variations in ethnobotanical knowledge, analyzing how those studies have conceptualized and operationalized ethnobotanical knowledge. We found that this type of research is recent but growing, and is concentrated in indigenous peoples of developing countries. We also found that studies differ on how they conceptualize and measure individual ethnobotanical knowledge. As it is th…
Long-Term (Secular) Change of Ethnobotanical Knowledge of Useful Plants: Separating Cohort and Age Effects
Anthropologists, conservation biologists, and psychologists have generally found a long-term (secular) decline of ethnobotanical knowledge among indigenous people. To estimate such knowledge loss, researchers have typically relied on a single cross-sectional data set to (a) measure knowledge among people of different ages, (b) compare measures between ages, and (c) infer a loss of knowledge if the old knew more than the young. We improve on the a…
Evaluating indices of traditional ecological knowledge: A Methodological Contribution
BACKGROUND: New quantitative methods to collect and analyze data have produced novel findings in ethnobiology. A common application of quantitative methods in ethnobiology is to assess the traditional ecological knowledge of individuals. Few studies have addressed reliability of indices of traditional ecological knowledge constructed with different quantitative methods. METHODS: We assessed the associations among eight indices of traditional ecol…

Moving beyond a Snapshot to Understand Changes in the Well-Being of Native Amazonians: Panel Evidence (2002-2006) from Bolivia
Forces such as the opening of trade, globalization, multinational corporate resource extraction, urbanization, acculturation, and colonization catalyze economic, ecological, and sociocultural change, which can threaten the well-being and habitat of native Amazonians. Understanding these forces is of paramount importance to improve the well-being of native Amazonians and to foster the conservation of biological diversity, yet most analyses of thes…

Does village inequality in modern income harm the psyche? Anger, fear, sadness, and alcohol consumption in a pre-industrial society
Is there a divide between local medicinal knowledge and Western medicine? a case study among native Amazonians in Bolivia
BACKGROUND: Interest in ethnomedicine has grown in the last decades, with much research focusing on how local medicinal knowledge can contribute to Western medicine. Researchers have emphasized the divide between practices used by local medical practitioners and Western doctors. However, researchers have also suggested that merging concepts and practices from local medicinal knowledge and Western science have the potential to improve public healt…
On the Measure of Income and the Economic Unimportance of Social Capital: Evidence from a Native Amazonian Society of Farmers and Foragers
Economists equate economic self-sufficiency (autarky) with low income and stress the economic role of social capital as a form of self-insurance in poor rural areas of developing nations. In contrast, anthropologists speak of the "original affluence" of foragers and see social capital as serving economic and social roles. Economists do not work with highly autarkic peoples such as part- or full-time foragers, and cultural anthropologists have not…

Ethnobotanical Skills and Clearance of Tropical Rain Forest for Agriculture: A Case Study in the Lowlands of Bolivia
Indigenous peoples are often considered potential allies in the conservation of biological diversity. Here we assess whether ethnobotanical skills of indigenous people contribute to a reduction in the clearance of tropical rain forest. We measured ethnobotanical skills of male household heads and area of rain forest cleared for agriculture among 128 households of Tsimane', a native Amazonian group in Bolivia. We used multivariate regressions to e…

Schooling's contribution to social capital: Study from a native Amazonian society in Bolivia
Understanding why traditional cultures weaken matters because they embody humanity's heritage. Schooling has been singled out as an abrader of traditional culture. We assess whether schooling erodes one aspect of traditional culture: social capital as shown by generosity to people outside the household. In industrial nations researchers find positive associations between social capital and schooling. We hypothesize that in pre‐industrial societie…
Acceptance and Perceptions of NORPLANT Among Users in San Francisco, USA
Two hundred and five women participating in a five-year clinical trial of NORPLANT and NORPLANT-2 were interviewed about their contraceptive and reproductive history, sources of information and knowledge of NORPLANT, experiences using the method, and the impressions of friends and family about the method. The most common reasons for trying the implants were dissatisfaction with other methods and perceptions about NORPLANT's ease of use. Forty-one…

Enzyme immunoassay for total immunoglobulin E in dried blood spots
Elevated circulating levels of total immunoglobulin E (IgE) are associated with both allergic disease and repeated macro‐parasitic infections. Population‐based research on IgE has been limited by the logistical constraints associated with obtaining and processing venipuncture blood samples. In this short report, we present an enzyme immunoassay protocol for quantifying circulating total IgE levels in capillary whole blood, collected from a finger…

Non-market Returns to Traditional Human Capital: Nutritional Status and Traditional Knowledge in a Native Amazonian Society
In industrial economies schooling produces positive non-market returns but do traditional forms of human capital also produce such returns, and do schooling and traditional human capital act as complements or substitutes in their association with well-being? Drawing on data from 450 adults (16+ years of age) from an indigenous Amazonian society in Bolivia, we estimate the association between traditional plant knowledge and nutritional status as m…
The effect of rainfall during gestation and early childhood on adult height in a foraging and horticultural society of the Bolivian Amazon
Recent research documents the effects of adverse conditions during gestation and early childhood on growth responses and health throughout life. Most research linking adverse conditions in early life with adult health comes from industrial nations. We know little about the plasticity of growth responses to environmental perturbations early in life among foragers and horticulturalists. Using 2005 data from 211 women and 215 men 20+ years of age fr…
Developmental changes in the relationship between leptin and adiposity among Tsimané children and adolescents
Leptin is thought to signal energy stores, thus helping the body balance energy intake and expenditure. However, the strong relationship between leptin and adiposity in populations with adequate nutrition or common obesity is not universal across ecologic contexts, and leptin often correlates only weakly, or not at all, with adiposity in populations of lean or marginally‐nourished males. To clarify whether the relationship between adiposity and l…

Can We Trust an Adult's Estimate of Parental School Attainment? Disentangling Social Desirability Bias and Random Measurement Error
Researchers often need to know the parental school attainment of adult subjects. When researchers cannot ask parents about their school attainment, they must ask adult offspring about the school attainment of their parents. We assess the accuracy of answers provided by adults about the school attainment of their parents with data from a native Amazonian society in Bolivia (Tsimane'). Offspring overestimate the school attainment of their parents. …
