The development of adaptive competence: Why cultural psychology is necessary and not just nice

Predictors of executive function among 2 year olds from a Thai birth cohort

Executive function (EF) is a critical skill for academic achievement. Research on the psychosocial and environmental predictors of EF, particularly among Southeast Asian, agricultural, and low income/rural populations, is limited. Our longitudinal study explored the influence of agricultural environmental, psychosocial, and temperamental factors on children's emerging EF. Three-hundred and nine farm worker women were recruited during the first trimester of pregnancy. We evaluated the effects of prenatal insecticide exposure and psychosocial factors on "cool" (i.e., cognitive: A-not-B task, looking version) and "hot" EF (i.e., affective, response inhibition) measures of emerging EF. Maternal urine samples were collected monthly during pregnancy, composited, and analyzed for dialkylphosphate (DAP) metabolites of organophosphate insecticides. Psychosocial factors included socioeconomic status, maternal psychological factors, and quality of mother-child behavioral interactions. Backward stepwise regressions evaluated predictors of children's EF at 12 (N = 288), 18 (N = 277) and 24 (N = 280) months of age. We observed different predictive models for cool EF, as measured by A-not-B task, vs. hot EF, as measured by response inhibition tasks. Report of housing quality as a surrogate for income was a significant predictor of emerging EF. However, these variables had opposite effects for cool vs. hot EF. More financial resources predicted better cool EF performance but poorer hot EF performance. Qualitative findings indicate that homes with fewer resources were in tribal areas where children must remain close to an adult for safety reasons. This finding suggests that challenging physical environments (e.g., an elevated bamboo home with no electricity or running water), may contribute to development of higher levels of response inhibition through parental socialization methods that emphasize compliance. Children who tended to show more arousal and excitability, and joy reactivity as young infants in the laboratory setting had better cognitive performance. In contrast, maternal emotional availability was a significant predictor of hot EF. As expected, increased maternal exposure to pesticides during pregnancy was associated with worse cognitive performance but was not associated with inhibitory control. Identifying risk factors contributing to the differential developmental pathways of cool and hot EF will inform prevention strategies to promote healthy development in this and other unstudied rural, low income Southeast Asian farming communities.

What is the expected human childhood? Insights from evolutionary anthropology

In psychological research, there are often assumptions about the conditions that children expect to encounter during their development. These assumptions shape prevailing ideas about the experiences that children are capable of adjusting to, and whether their responses are viewed as impairments or adaptations. Specifically, the expected childhood is often depicted as nurturing and safe, and characterized by high levels of caregiver investment. Here, we synthesize evidence from history, anthropology, and primatology to challenge this view. We integrate the findings of systematic reviews, meta-analyses, and cross-cultural investigations on three forms of threat (infanticide, violent conflict, and predation) and three forms of deprivation (social, cognitive, and nutritional) that children have faced throughout human evolution. Our results show that mean levels of threat and deprivation were higher than is typical in industrialized societies, and that our species has experienced much variation in the levels of these adversities across space and time. These conditions likely favored a high degree of phenotypic plasticity, or the ability to tailor development to different conditions. This body of evidence has implications for recognizing developmental adaptations to adversity, for cultural variation in responses to adverse experiences, and for definitions of adversity and deprivation as deviation from the expected human childhood.

The Hidden Talents Approach: Theoretical and Methodological Challenges

It is well established that people living in adverse conditions tend to score lower on a variety of social and cognitive tests. However, recent research shows that people may also develop 'hidden talents', that is, mental abilities that are enhanced through adversity. The hidden talents program sets out to document these abilities, their development, and their manifestations in different contexts. Although this approach has led to new insights and findings, it also comes with theoretical and methodological challenges. Here, we discuss six of these challenges. We conclude that the hidden talents approach is promising, but there is much scope for refining ideas and testing assumptions. We discuss our goal to advance this research program with integrity despite the current incentives in science.

Hidden talents in harsh conditions? A preregistered study of memory and reasoning about social dominance

Although growing up in stressful conditions can undermine mental abilities, people in harsh environments may develop intact, or even enhanced, social and cognitive abilities for solving problems in high-adversity contexts (i.e. 'hidden talents'). We examine whether childhood and current exposure to violence are associated with memory (number of learning rounds needed to memorize relations between items) and reasoning performance (accuracy in deducing a novel relation) on transitive inference tasks involving both violence-relevant and violence-neutral social information (social dominance vs. chronological age). We hypothesized that individuals who had more exposure to violence would perform better than individuals with less exposure on the social dominance task. We tested this hypothesis in a preregistered study in 100 Dutch college students and 99 Dutch community participants. We found that more exposure to violence was associated with lower overall memory performance, but not with reasoning performance. However, the main effects of current (but not childhood) exposure to violence on memory were qualified by significant interaction effects. More current exposure to neighborhood violence was associated with worse memory for age relations, but not with memory for dominance relations. By contrast, more current personal involvement in violence was associated with better memory for dominance relations, but not with memory for age relations. These results suggest incomplete transfer of learning and memory abilities across contents. This pattern of results, which supports a combination of deficits and 'hidden talents,' is striking in relation to the broader developmental literature, which has nearly exclusively reported deficits in people from harsh conditions.

The transition of object to mental manipulation: beyond a species-specific view of intelligence

Many attempts have been made to classify and evaluate the nature of intelligence in humans and other species (referred to as the 'g' factor in the former and the G factor in the latter). The search for this essential structure of mental life has generated various models and definitions, yet open questions remain. Specifically, referring to intelligence by overemphasizing the anthropocentric terminology and its ethnocentric overlay is insufficient to account for individual differences and limits its generalizability in biological and cultural contexts. The present work is an attempt to adopt a different perspective on the 'g/G' factor and its measurement. We suggest that intelligence, or g/G, is reflected in a biological capacity that evolved from object manipulation in animals, into mental manipulation in humans, in response to various environmental conditions.

The Strengths of People in Poverty

On average, psychological variables are often statistically different in people living in poverty compared with people living in affluence. The default academic response to this pattern is often the deficit model: Poverty damages or impairs brain function, which leads to poor performance that only exacerbates the poverty. Deficits and damage are real phenomena. However, there are also other processes: People living in poverty may have made reasonable psychological responses to their circumstances or may have developed strengths that enhance their ability to cope with challenges in their lives. We illustrate these points by discussing the linked examples of time preference, early reproduction, and hidden talents. We argue for a balanced approach to the psychology of poverty that integrates deficit and strengths-based models. Future research could focus on the ways in which impairment and adaptation interact.

Bronfenbrenner's Bioecological Theory Revision: Moving Culture From the Macro Into the Micro

Bronfenbrenner's bioecological theory of human development is one of the most widely known theoretical frameworks in human development. In spite of its popularity, the notion of culture within the macrosystem, as a separate entity of everyday practices and therefore microsystems, is problematic. Using the theoretical and empirical work of Rogoff and Weisner, and influenced as they are by Vygotsky's sociocultural perspective, we reconceptualize Bronfenbrenner's model by placing culture as an intricate part of proximal development processes. In our model, culture has the role of defining and organizing microsystems and therefore becomes part of the central processes of human development. Culture is an ever changing system composed of the daily practices of social communities (families, schools, neighborhoods, etc.) and the interpretation of those practices through language and communication. It also comprises tools and signs that are part of the historical legacy of those communities, and thus diversity is an integral part of the child's microsystems, leading to culturally defined acceptable developmental processes and outcomes.

Speculations on the Role of Successful Intelligence in Solving Contemporary World Problems †

In this article, I argue that conventional views of intelligence and its measurement have contributed toward at least some of the societal problems of today. I suggest that to escape from a degenerative process, society needs to consider the importance not only of intelligence, as conventionally defined but also of successful intelligence, involving in addition to conventional analytical intelligence, common sense, creativity, and wisdom.

Why Should We All Be Cultural Psychologists? Lessons From the Study of Social Cognition

I call the attention of psychologists to the pivotal role of cultural psychology in extending and enriching research programs. I argue that it is not enough to simply acknowledge the importance of culture and urge psychologists to practice cultural psychology in their research. I deconstruct five assumptions about cultural psychology that seriously undermine its contribution to the building of a true psychological science, including that cultural psychology (a) is only about finding group differences, (b) does not appertain to group similarities, (c) concerns only group-level analysis, (d) is irrelevant to basic psychological processes, and (e) is used only to confirm the generalizability of theories. I discuss how cultural psychology can provide unique insights into psychological processes and further equip researchers with additional tools to understand human behavior. Drawing lessons from the 20 years of cultural research that my colleagues and I have done on the development of social cognition, including autobiographical memory, future thinking, self, and emotion knowledge, I demonstrate that incorporating cultural psychology into research programs is not only necessary but also feasible.

Beyond Risk and Protective Factors: An Adaptation-Based Approach to Resilience

How does repeated or chronic childhood adversity shape social and cognitive abilities? According to the prevailing deficit model, children from high-stress backgrounds are at risk for impairments in learning and behavior, and the intervention goal is to prevent, reduce, or repair the damage. Missing from this deficit approach is an attempt to leverage the unique strengths and abilities that develop in response to high-stress environments. Evolutionary-developmental models emphasize the coherent, functional changes that occur in response to stress over the life course. Research in birds, rodents, and humans suggests that developmental exposures to stress can improve forms of attention, perception, learning, memory, and problem solving that are ecologically relevant in harsh-unpredictable environments (as per the specialization hypothesis). Many of these skills and abilities, moreover, are primarily manifest in currently stressful contexts where they would provide the greatest fitness-relevant advantages (as per the sensitization hypothesis). This perspective supports an alternative adaptation-based approach to resilience that converges on a central question: “What are the attention, learning, memory, problem-solving, and decision-making strategies that are enhanced through exposures to childhood adversity?” At an applied level, this approach focuses on how we can work with, rather than against, these strengths to promote success in education, employment, and civic life.
