SummaryCountries vary in their geographical and cultural properties. Only a few studies have explored how such variations influence how humans navigate or reason about space [1–7]. We predicted that these variations impact human cognition, resulting in an organized spatial distribution of cognition at a planetary-wide scale. To test this hypothesis we developed a mobile-app-based cognitive task, measuring non-verbal spatial navigation ability in more than 2.5 million people, sampling populations in every nation state. We focused on spatial navigation due to its universal requirement across cultures. Using a clustering approach, we find that navigation ability is clustered into five distinct, yet geographically related, groups of countries. Specifically, the economic wealth of a nation was predictive of the average navigation ability of its inhabitants, and gender inequality was predictive of the size of performance difference between males and females. Thus, cognitive abilities, at least for spatial navigation, are clustered according to economic wealth and gender inequalities globally, which has significant implications for cross-cultural studies and multi-centre clinical trials using cognitive testing.

AbstractCultural and geographical properties of the environment have been shown to deeply influence cognition and mental health. However, how the environment experienced during early life impacts later cognitive abilities remains poorly understood. Here, we used a cognitive task embedded in a video game to measure non-verbal spatial navigation ability in 442,195 people from 38 countries across the world. We found that on average, people who reported having grown up in cities have worse navigation skills than those who grew-up outside cities, even when controlling for age, gender, and level of education. The negative impact of cities was stronger in countries with low average Street Network Entropy, i.e. whose cities have a griddy layout. The effect was smaller in countries with more complex, organic cities. This evidences the impact of the environment on human cognition on a global scale, and highlights the importance of urban design on human cognition and brain function.

Since the mid-2000s, India has been beset by widespread farmer protests against “land grabs.” Dispossession without Development argues that beneath these conflicts lay a profound transformation in the political economy of land dispossession. While the Indian state dispossessed land for public-sector industry and infrastructure for much of the 20th century, the adoption of neoliberal economic policies since the early 1990s prompted India’s state governments to become land brokers for private real estate capital—most controversially, for Special Economic Zones (SEZs). Using long-term ethnographic research, the book demonstrates the consequences of this new regime of dispossession for a village in Rajasthan. Taking us into the diverse lives of villagers dispossessed for one of North India’s largest SEZs, it shows how the SEZ destroyed their agricultural livelihoods, marginalized their labor, and excluded them from “world-class” infrastructure—but absorbed them into a dramatic real estate boom. Real estate speculation generated a class of rural neo-rentiers, but excluded many and compounded pre-existing class, caste, and gender inequalities. While the SEZ disappointed most villagers’ expectations of “development,” land speculation fractured the village and disabled collective action. The case of “Rajpura” helps to illuminate the exclusionary trajectory of capitalism that underlay land conflicts in contemporary India—and explain why the Indian state is struggling to pacify farmers with real estate payouts. Using the extended case method, Dispossession without Development advances a sociological theory of dispossession that has relevance beyond India.

Traditional attempts to understand the evolution of human cognition compare humans with other primates. This research showed that relative brain size covaries with cognitive skills, while adaptations that buffer the developmental and energetic costs of large brains (e.g. allomaternal care), and ecological or social benefits of cognitive abilities, are critical for their evolution. To understand the drivers of cognitive adaptations, it is profitable to consider distant lineages with convergently evolved cognitions. Here, we examine the facilitators of cognitive evolution in corvid birds, where some species display cultural learning, with an emphasis on family life. We propose that extended parenting (protracted parent–offspring association) is pivotal in the evolution of cognition: it combines critical life-history, social and ecological conditions allowing for the development and maintenance of cognitive skillsets that confer fitness benefits to individuals. This novel hypothesis complements the extended childhood idea by considering the parents' role in juvenile development. Using phylogenetic comparative analyses, we show that corvids have larger body sizes, longer development times, extended parenting and larger relative brain sizes than other passerines. Case studies from two corvid species with different ecologies and social systems highlight the critical role of life-history features on juveniles’ cognitive development: extended parenting provides a safe haven, access to tolerant role models, reliable learning opportunities and food, resulting in higher survival. The benefits of extended juvenile learning periods, over evolutionary time, lead to selection for expanded cognitive skillsets. Similarly, in our ancestors, cooperative breeding and increased group sizes facilitated learning and teaching. Our analyses highlight the critical role of life-history, ecological and social factors that underlie both extended parenting and expanded cognitive skillsets. This article is part of the theme issue ‘Life history and learning: how childhood, caregiving and old age shape cognition and culture in humans and other animals’.

Abstract Many studies find gender differences in how older adults’ report on their memory, perform on cognitive testing, and manage functional impairments that can accompany cognitive impairment. Thus, understanding gender’s effects in aging and Alzheimer’s research is key for advancing methods to prevent, slow, manage, and diagnosis cognitive impairment. Our study, CoGenT3 – The study of Cognition and Gender in Three Generations – seeks to disambiguate the effects of gender on cognition in order to inform a conceptual model, guide innovations in measurement, and support future study. To accomplish this ambitious goal, we have gathered an interdisciplinary team with expertise in psychology, cognition, sexual and gender minorities, library science, measurement, quantitative methods, qualitative methods, and gender and women’s studies. The team benefits from the intersections of expertise in being able to build new research ideas, gain novel insights, and evaluate a wide-range of actions and re-actions but this novelty can also raise challenges.

Individual differences in scene imagination, autobiographical memory recall, future thinking and spatial navigation have long been linked with hippocampal structure in healthy people, although evidence for such relationships is, in fact, mixed. Extant studies have predominantly concentrated on hippocampal volume. However, it is now possible to use quantitative neuroimaging techniques to model different properties of tissue microstructure in vivo such as myelination and iron. Previous work has linked such measures with cognitive task performance, particularly in older adults. Here we investigated whether performance on scene imagination, autobiographical memory, future thinking and spatial navigation tasks was associated with hippocampal grey matter myelination or iron content in young, healthy adult participants. Magnetic resonance imaging data were collected using a multi-parameter mapping protocol (0.8 mm isotropic voxels) from a large sample of 217 people with widely-varying cognitive task scores. We found little evidence that hippocampal grey matter myelination or iron content were related to task performance. This was the case using different analysis methods (voxel-based quantification, partial correlations), when whole brain, hippocampal regions of interest, and posterior:anterior hippocampal ratios were examined, and across different participant sub-groups (divided by gender and task performance). Variations in hippocampal grey matter myelin and iron levels may not, therefore, help to explain individual differences in performance on hippocampal-dependent tasks, at least in young, healthy individuals.

Abstract INTRODUCTION Subjective cognitive dysfunction is an important outcome measure in neuro-oncology and may provide additional information beyond performance-based neuropsychological testing. The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is a frequently used quality of life (QoL) measure that includes indices of physical, emotional, social, and neurologic aspects of disease, but does not measure cognitive concerns. This study seeks to develop and validate an index of self-reported cognition derived from existing items on the FACT-Br. METHODS 145 patients (Mage=51.08, Medu=15.63) with heterogeneous brain tumor diagnoses completed neuropsychological evaluation including cognitive testing and self-report measures. Nine FACT-Br items regarding cognition were combined to form the Cognitive Index (CI). Reliability of the CI was measured with Cronbach’s alpha. Concurrent validity was assessed by correlating the CI with the Patient-Reported Outcomes Measurement Information System (PROMIS) Cognitive Abilities-8 or PROMIS Cognitive Concerns-8. Discriminant validity was assessed by correlation of the CI with other FACT-Br indices and the Beck Depression and Anxiety Inventories (BDI, BAI). RESULTS Internal consistency within the CI was high (Cronbach’s a 0.864). The CI correlated strongly with the PROMIS-Abilities (r =.680; p< 0.001) and PROMIS-Concerns (r=.780; p< 0.001) indicating high convergent validity. Moderate correlations were observed between the CI and the physical and functional subscales of the FACT (r=.453 and .555), whereas correlations with the social and emotional functioning subscales were weaker (r=.381 and .325). The FACT-Br-CI correlated strongly with BDI (r=-.622) and more weakly with the BAI (r=-.344). Consistent with prior literature, the CI showed modest correlations with neuropsychological measures, including verbal memory encoding (r=.300), verbal fluency (r=.252) and a composite measure of cognition (r=.249; all p’s< .01). CONCLUSIONS The FACT-Br-CI is a reliable and valid measure of self-reported cognition. Studies that include the FACT-Br could be retrospectively analyzed to assess self-reported cognitive outcomes, enriching the information gained from prior research.

Evolutionary theory suggests that commonly found sex differences are largest in healthy populations and smaller in populations that have been exposed to stressors. We tested this idea in the context of men’s typical advantage (vs. women) in visuospatial abilities (e.g., mental rotation) and women’s typical advantage (vs. men) in social-cognitive (e.g., facial-expression decoding) abilities, as related to frequent binge drinking. Four hundred nineteen undergraduates classified as frequent or infrequent binge drinkers were assessed in these domains. Trial-level multilevel models were used to test a priori Sex × Group (binge drinking) interactions for visuospatial and social-cognitive tasks. Among infrequent binge drinkers, men’s typical advantage in visuospatial abilities and women’s typical advantage in social-cognitive abilities was confirmed. Among frequent binge drinkers, men’s advantage was reduced for one visuospatial task (Δ d = 0.29) and eliminated for another (Δ d = 0.75), and women’s advantage on the social-cognitive task was eliminated (Δ d = 0.12). Males who frequently engaged in extreme binges had exaggerated deficits on one of the visuospatial tasks, as did their female counterparts on the social-cognitive task. The results suggest sex-specific vulnerabilities associated with recent, frequent binge drinking, and support an evolutionary approach to the study of these vulnerabilities.

This paper proposes that there is a need to push beyond the popular discourses of ‘flexibility’ and ‘work-life balance’. Developing a feminist-Bourdieuian approach and drawing on three illustrative case studies from my interview research with 27 mothers in the UK, I show the importance of maintaining a focus on class and gender inequalities. In the first part of the paper the concepts of capitals, dependencies and habitus which shaped, and were shaped by, this interview research are discussed. An analysis of three women's accounts of their experiences across work and family life is then used to illustrate that although these women all used terms such as ‘flexibility’ and ‘juggling’ in describing their work, the experience of that work was crucially influenced by their histories and current positioning. Tracing each of these women's trajectories from school, attention is focused on the influence of differential access to capitals and relations of dependency in the emergence of their dispositions toward work. Overall, the paper points to the significance of examining the classed and gendered dimensions of women's experiences of employment and motherhood.

Our article aims to study the attitudes of the elite to family life and gender equality. This is a social group who still experiences significant gender imbalances. We focus on attitudes to family life, which has thus far been underresearched in elite literature. With the help of the analysis of 34 individual interviews with members of the Hungarian political, economic, and cultural elite, we identify and present three types of narrative identities: dominant, deferential, and egalitarian. The main finding from our qualitative content analysis is that egalitarian partnership norms which were discussed in every narrative and gender equality appear in most cases as a norm among the elite. However, there is a narrative tension between this norm and the couples’ actual experiences of their family life. We conclude our article with some comments on how the ideology of egalitarian essentialism strengthens gender inequalities reinforcing the underrepresentation of women in elite positions.
