While early-life adverse experiences have been linked to late-life cognitive decline, few studies have explored war exposure. Paradoxically, one study even indicated a late-life cognitive advantage of early-childhood war exposure. In the present study, we explored these associations.
Methods:
We examined older adults exposed to World War II (1940–1944; n = 1179) and the subsequent Civil war (1946–1949; n = 962) in Greece during early and middle childhood with a comprehensive neuropsychological assessment and for ApoE-ε allele status, including demographic information and medical history.
Results:
Higher cognitive performance in language tasks predicted middle childhood, relative to early childhood, WWII-exposure group membership (B = .316, p = .038, OR:1.372, 95%CI:1.018–1.849), primarily for men, while higher attention/speed (B = .818, p = .002, OR:2.265, 95%CI:1.337–3.838) and total cognitive score (B = .536, p = .040, OR:1.709, 95%CI:1.026–2.849) were predictors of belonging to the middle-childhood group, only in men. Individuals who did not meet criteria for Mild Cognitive Impairment (MCI)/dementia were more likely to belong to the middle-childhood war-exposure group. Similarly, for the Civil war, higher cognitive scores and reduced likelihood to meet criteria for MCI/dementia were predictors of middle, relative to early childhood war exposure group membership (visuospatial score: B = .544, p = .001, OR:1.723, 95%CI:1.246–2.381, MMSE: B = .134, p = .020, OR:1.143, 95%CI:1.021–1.297), primarily for women. Results remained consistent when adjusting for multimorbidity, sex, education, current age, depression, and anxiety.
Conclusion:
The present findings suggest that better cognitive performance and lower likelihood of MCI or dementia were associated with being exposed to significant hardships, such as war, during middle childhood, regardless of potentially confounding factors. Further studies are needed to shed light on this relationship.
The Foundling Hospital was established in London in 1739 to save impoverished infants from destitution and abandonment by separating them from their mothers and raising them in an institutional setting. The Hospital, which also housed an art collection, concert series, and fashionable park, became a monument to the largess of the benefactors willing to support the reshaping of supposedly unwanted babies into “worthy” citizens useful to their nation. In 2024 the Coram Foundation digitized parts of its voluminous archive from the eighteenth and nineteenth centuries, making these records available to the public in unprecedented ways. Through a close examination of the material artifacts of the Hospital, this analysis of the first few decades of this institution makes visible the uneasy tension between the perspective of the benefactors and the experiences of foundlings from the moment of separation from their birth parent(s) through their years associated with the Foundling Hospital.
This longitudinal study examined the impact of L2 acquisition on the narrative development of L1-Turkish dominant children who were exposed to L2-English immersion compared to their peers who were not exposed to L2-English immersion but to L1-Turkish. The study involved 155 children, aged 5, 7, and 9 at Time 1, assessing their narrative production, linguistic complexity, and narrative comprehension over a one-year period. Children who were exposed to L2-English immersion received intensive L2-English instruction from a young age while living in an L1-Turkish dominant society. For both time points, L2-English immersion children performed better than L1-Turkish dominant children for L1 narrative production. While no overall group differences emerged in linguistic complexity, L2-English immersion children exhibited higher complexity in L1 relative to their L2 for both time points, suggesting a facilitative effect of early L2 exposure on L1 narrative structure. These findings support the idea that bilingualism may foster narrative skills. These results highlight the importance of early bilingual education, especially when both languages are equally supported, contributing to children’s overall language development.
Variability in the second language (L2) referential choice could be due to lower language proficiency in the L2 or cross-linguistic influence. We compare the L2 English referential choices of bilinguals of typologically different languages (Spanish and English, null subject and non-null subject) to those of bilinguals of typologically similar languages (Dutch and English, both non-null subject and both using pronouns similarly in the target context). Bilinguals’ performance was further compared to that of a group of functional monolingual English speakers. Both bilingual groups were highly proficient, to explore whether high proficiency would attenuate differences with monolinguals. Participants completed a picture-description task eliciting references to antecedents in two-character contexts. Performance was comparable among all three groups in all conditions—evidence that cross-linguistic influence did not play a role for bilingual referential choices. These results thus show that highly proficient bilinguals of both typologically different and similar languages can perform comparably to monolinguals.
Thai researchers developed a new self-report measure of executive functions for adolescents based on Diamond’s framework (the Behavioral Inventory Measure of Executive Functions [BIMEFs]). How it was developed, its psychometric properties, and norms by sex and age are reported here.
Method:
An independent panel of experts evaluated the content validity of BIMEFs. Reliability was checked using Cronbach’s alpha with a sample of 45 secondary students. 1,865 students, ages 12 – 18 years (65% female) from across Thailand participated in the normative study.
Results:
The BIMEFs consists of 42 items that assess inhibitory control (IC), working memory (WM), and cognitive flexibility (CF), including eight subcomponents. For all items, the index of item-objective congruence was >0.5 and Cronbach’s alpha was >0.7. Confirmatory factor analysis (CFA) showed the adjusted goodness of fit index to be 0.9. The strongest sex difference was for IC. Students of 13 years scored lower on EFs overall, IC, WM, CF, and all subcomponents than older students. Self-control, verbal working memory, and being able to change perspectives showed the most pronounced differences by age.
Conclusion:
The BIMEFs, which is designed to be culturally-appropriate for Thailand and cross-culturally generally, is the first EF questionnaire based on Diamond’s framework. It shows good psychometric properties and sensitivity to age and sex differences. It indicates that IC development, at least in Thailand, plateaus earlier than WM and CF and that CF shows a more protracted development during adolescence than IC or WM.
The pervasive integration of digital media into daily life is reshaping how individuals encounter and internalize harmful contents. Unrestricted access exposes students to emotionally disruptive materials, including depictions of violence, substance use, and harassment, raising concerns about its impact on well-being. This study examines a serial mediation model linking antisocial media exposure to subjective well-being (SWB) through school-based victimization as sequential pathways. Using data from 326 high school students in Nigeria, we applied partial least squares structural equation modeling to test hypothesized relationships. Results indicate that antisocial media exposure was not directly associated with SWB but significantly predicted experiences of teacher and peer victimization. Peer victimization mediated the relationship between antisocial media exposure and SWB (β = −0.023, 95% CI: [−0.054, −0.004], p < 0.05). Furthermore, antisocial media exposure increased the likelihood of teacher victimization, which facilitated peer victimization, ultimately compromising SWB (β = −0.030, 95% CI: [−0.058, −0.011], p < 0.05). Effects varied by gender and academic level, underscoring intersectional risks linked to media exposure. Findings highlight the need for targeted interventions addressing both teacher and peer victimization in resource-constrained educational contexts.
Play has a significant role in children's learning and development. Play in the Early Years examines the central questions about play from the perspectives of children, families and educators, providing a comprehensive introduction to the theory and practice of play for children from birth to eight years. In its fourth edition, Play in the Early Years has been thoroughly updated in line with the revised Early Years Learning Framework and the new version of the Australian Curriculum. It takes both a both a theoretical and a practical approach, and covers recent research into conceptual play and wellbeing. The text looks at social, cultural and institutional approaches to play, and explores a range of strategies for successfully integrating play into early years settings and primary classrooms. Each chapter features case studies and play examples, with questions and reflection activities incorporated throughout to enhance learners' understanding.
The increasing levels of job demands and work stress experienced daily by workers in multiple contexts have increased the experience of the need for recovery after work. This study aims to provide validity evidence for the Danish Need for Recovery (NFR) Scale. We analyzed the psychometric properties of the scale, its factor structure, internal consistency, measurement invariance, and validity based on relationships with other variables (job stress, general health, and affective states) in two samples of Spanish workers. The results obtained through exploratory and confirmatory factor analyses strongly support the unidimensional structure of the Spanish version of the NFR in its full eight-item version after eliminating one item not applicable in our cultural context, with good data fit. The values obtained regarding internal consistency, besides measurement invariance across groups, ensure the scale’s reliability and applicability. The validity and associations with other constructs tested were also confirmed in the hypothesized relationships with the respective variables analyzed. However, the short three-item version does not present a better fit compared to the full version in its Spanish validation. The Spanish adaptation of the Danish NFR scale in its full eight-item version constitutes a reliable and valid instrument for the assessment of this construct. The methodological and practical implications of the Spanish version of the NFR scale are detailed in the discussion.
Researchers have long speculated about the evolutionary benefits of religiosity. One explanation for the evolution of religious ritual is that rituals signal commitment to co-religionists. As a major domain of prosocial behavior, alloparental care – or care directed at children by non-parents – is a plausible benefit of religious signaling. The religious alloparenting hypothesis posits that parents who signal religious commitment receive greater alloparental support. Prior research on religiosity, cooperation, and allocare tends to treat individuals as isolated units, despite the inherent collective nature of religious cooperation. Here, we address this limitation in a survey-based study of 710 parents in rural Bangladesh. Instead of focusing only on mothers, we consider the interplay between both mothers and fathers in eliciting allocare, and leverage variation in the covertness of religious rituals to test a key mechanistic assumption linking religious ritual with cooperation. We find that parents who practice religious rituals more frequently receive greater alloparental support from co-religionists. This effect is moderated by parent gender, as well as variation in the visibility of religious rituals. Women’s private practices positively affect only those alloparents with whom they share a household, while men’s public practices positively affect alloparents more broadly.
Language deficits are frequently described by patients with multiple sclerosis (MS); however, objective characterization remains somewhat limited due to its omission from standard MS cognitive evaluation and the inconsistent findings that arise from current language measures.
Objective:
To establish alternative approaches to characterizing single-word level language in MS, this study (i) validates the Sydney Language Battery (SYDBAT) visual confrontation naming subtest and (ii) examines the insights provided by examining naming errors and latencies.
Methods:
40 MS patients from Royal Melbourne Hospital’s Cognitive Neuroimmunology Clinic and 40 matched controls completed a series of neuropsychological tests, including the SYDBAT and ‘gold standard’ confrontation naming task, the Boston Naming Test (BNT). Error types and latencies on the SYDBAT were extracted from assessment audio recordings.
Results:
SYDBAT and BNT scores were highly correlated (r = 0.81, p < .001) and these tasks reported comparable receiver operating characteristic curves (p = .091). Latency analysis captured lexical retrieval difficulties, with patients displaying significantly longer mean latencies than controls on the SYDBAT (p = .012, β = 0.54).
Conclusions:
These findings support the validity of the SYDBAT and value of the latency analysis in characterizing language impairment in MS. Use of the SYDBAT and latency considerations contribute to a broader assessment with a briefer administration time compared to gold-standard evaluation. The study thereby offers clinicians an enhanced toolkit to more effectively and appropriately evaluate language functioning and supplement standard cognitive evaluation in this population.
Through reading this chapter, you will gain insights into Vygotsky’s cultural-historical conception of play and the range of contemporary models of play that have been informed by cultural-historical theory.
Without counting, adult and infant humans and many other animals are able to compare amounts of solids, intensities of stimuli, and quantities of discrete objects or stimuli – if the sizes of the sets being compared differ by a large enough ratio. For example, an infant of a given age might be able to identify the larger of two sets, where one set consists of forty items and the other set ten items, so a ratio of 4:1. The same infant might not be able to recognize which was larger, a set of 10 items and a set of 5. The cognitive system that makes these > or < discriminations is called the analog magnitude system, or the approximate magnitude system (AMS). The principle neuropsychological substrate of this system is in the lateral segment of the intraparietal sulcus. This same region is activated when people compare social ranks.

Concrete Operations of One-to-One Correspondence for Equality Matching, Arbitrary Symbolism for Market Pricing, Combinations of Conformations, and What Children Discover
To conform equality matching, the most effective, frequent, intuitive, and widespread conformations consist of concrete operations of one-to-one correspondence. This may take the form of aligning things side by side, or doing rounds of “one for you, one for you, and one for you.” Starting together and then stopping at the same time assures temporal equality of labor. Piaget originally formulated the concept of concrete operations to describe what he inferred to be a stage of cognitive development in which children inferred equality between quantities. Humans have developed various technologies for doing concrete operations of one-to-one correspondence, such as ballots, pan balances, and placeholder items showing whose turn it is. It turns out that even infants recognize concrete operations of one-to-one correspondence, which they expect agents to use by default when distributing items between agents. Nonhuman animals have not been observed to do this.

Modes of Minding Social Action: Bodily Indices of Unity, Dimensional Icons of Rank, Concrete Matching Operations of Equality, Arbitrary Symbols of Proportions
There four fundamental relational models: communal sharing, authority ranking, equality matching, and market pricing. Each of them utilizes a distinct conformation system to represent, communicate, coordinate, motivate, and evaluate social relationships of that kind. The conformation systems are indexical equivalence of bodies, iconic dimensions of rank, concrete operations of one-to-one matching, and purely conventional symbolism of proportions. The chapter also introduces complementarity theory, which posits innate structures that can function only in conjunction with cultural complements. It concludes by saying that the book is intended to be an antitheses to symbolic anthropology.
People imagine high-status persons as tall, and in premodern art often depict rulers as bigger than others. Similarly, to evoke suitable emotions while representing the “greatness” of the Buddha and high gods, people often make statues of them as large as their technology permits. Rulers usually wear headdresses that make them seem tall, and are depicted wearing them. Rulers also tend to wear voluminous robes that make them appear especially large. Modern banners and statues of great political leaders depict them as huge, and their statues are often placed atop tall columns. Another conformation of authority ranking consists of lowering one’s head, bowing, kneeling, or prostrating oneself so as to be below a ruler or other person of “higher” rank. Rulers may place themselves on a dais.
