The link between non-human primate vocalizations and cognition is not constrained by maturation alone: Evidence from healthy preterm infants.

To acquire language, infants must not only identify the signals of their language(s), but also discover how these signals are connected to meaning. By 3 months of age, infants' native language, non-native languages, and vocalizations of non-human primates support infants' formation of object categories-a building block of cognition. But by 6 months, only the native language exerts this cognitive advantage. Prior work with preterm infants indicates that maturation constrains this developing link between the native language and cognition. Here, we assess whether maturation exerts similar constraints on the influence of non-human primate vocalizations on infant categorization. Cross-sectional growth curve analyses of new data from preterm infants and extant data from fullterm infants indicate that developmental tuning of this signal's influence on categorization is best predicted by infants' chronological age, and not gestational status. This evidence, together with prior work, suggests that as infants tune the initially broad set of signals that support early cognition, they are guided by two independent processes: maturation constrains the expression of a link between their native language and cognition, while the influence of non-linguistic signals are guided by other factors, such as postnatal age and experience.

Theorizing "Place" in Aging in Place: The Need for Territorial and Relational Perspectives.

This paper argues for a greater theorization of "place" within aging-in-place research. It extends calls for a relational conceptualization of place by demonstrating the need for aging-in-place researchers to also pay greater attention to territorial aspects of place. This complementary understanding will help establish a new spatial grammar within aging-in-place research, that not only would improve conceptual clarity to aging in place, but would also support a more critical engagement of aging in place in questions of inequality. The paper demonstrates this through a discussion of 2 forms of inequality pertinent to older people: the uneven capacity of places to support older people and experiences of social exclusion in relation to place attachment for older people from marginalized groups.

Children's susceptibility to online misinformation.

Children have a reputation for credulity that is undeserved; even preschoolers have proven adept at identifying implausible claims and unreliable informants. Still, the strategies children use to identify and reject dubious information are often superficial, which leaves them vulnerable to accepting such information if conveyed through seemingly authoritative channels or formatted in seemingly authentic ways. Indeed, children of all ages have difficulty differentiating legitimate websites and news stories from illegitimate ones, as they are misled by the inclusion of outwardly professional features such as graphs, statistics, and journalistic layout. Children may not be inherently credulous, but their skepticism toward dubious information is often shallow enough to be overridden by the deceptive trappings of online misinformation.

Many preschoolers do not distinguish the possible from the impossible in a marble-catching task.

Do preschoolers differentiate events that might and might not happen from events that cannot happen? The current study modified Redshaw & Suddendorf's "Y-shaped tube task" to test how the ability to distinguish mere possibilities from impossibilities emerges over ontogenesis. In the Y-shaped tube task, the experimenter holds a ball above a tube shaped like an upside-down "Y" and asks a participant to catch it. A participant who identifies the two possible paths the ball can take should cover both exits at the bottom of the Y. But children might cover both exits without identifying both possibilities. For example, there are two good places to put hands, so they might just put one hand in each place. This does not require checking whether there is a path from the entrance to each exit. If children cover both exits because they have identified two possible paths for the ball, then they should differentiate exits where it is possible for the ball to come out from impossible exits, where there is no path from the entrance to the exit. In total, 24 36-month-olds and 24 48-month-olds were tested. Less than 20% of 36-month-olds and only about half of 48-month-olds distinguished between possible and impossible exits. Children who do not distinguish the possible from the impossible might not be evaluating possibilities at all. Results converge with existing literature suggesting that action planning that is sensitive to incompatible possibilities often emerges after the fourth birthday.

It's not just what we don't know: The mapping problem in the acquisition of negation.

How do learners learn what no and not mean when they are only presented with what is? Given its complexity, abstractness, and roles in logic, truth-functional negation might be a conceptual accomplishment. As a result, young children's gradual acquisition of negation words might be due to their undergoing a gradual conceptual change that is necessary to represent those words' logical meaning. However, it's also possible that linguistic expressions of negation take time to learn because of children's gradually increasing grasp of their language. To understand what no and not mean, children might first need to understand the rest of the sentences in which those words are used. We provide experimental evidence that conceptually equipped learners (adults) face the same acquisition challenges that children do when their access to linguistic information is restricted, which simulates how much language children understand at different points in acquisition. When watching a silenced video of naturalistic uses of negators by parents speaking to their children, adults could tell when the parent was prohibiting the child and struggled with inferring that negators were used to express logical negation. However, when provided with additional information about what else the parent said, guessing that the parent had expressed logical negation became easy for adults. Though our findings do not rule out that young learners also undergo conceptual change, they show that increasing understanding of language alone, with no accompanying conceptual change, can account for the gradual acquisition of negation words.

Could it? Should it? Cognitive reflection facilitates children's reasoning about possibility and permissibility.

Children can be unduly skeptical of events that violate their expectations, claiming that these events neither could happen nor should happen even if the events violate no physical or social laws. Here, we explored whether children's reasoning about possibility and permissibility-modal cognition-is aided by cognitive reflection, or the disposition to privilege analysis over intuition. A total of 99 children aged 4 to 11 years judged the possibility and permissibility of several hypothetical events, and their judgments were compared with their scores on a developmental version of the Cognitive Reflection Test (CRT-D). Children's CRT-D scores predicted their ability to differentiate possible events from impossible ones and their ability to differentiate impermissible events from permissible ones as well as their ability to differentiate possibility from permissibility in general. Such differentiations were predicted by children's CRT-D scores independent of age and executive function. These findings suggest that mature modal cognition may require the ability to reflect on, and override, the intuition that unexpected events cannot happen.

Universities as Intermediary Organizations: Catalyzing the Construction of an Age-Friendly City in Hong Kong.

Background and Objectives: The construction of an Age-Friendly City (AFC) requires active contribution from relevant interest groups including older adults, nonprofit organizations, and policy-makers. However, given that relevant interest groups may have limited resources, knowledge, and skills, as well as unique contextual factors, they often require help from intermediary organizations-actors that aim to build interest groups' capabilities. Our objectives were to examine the functions of universities, as an example of intermediary organizations, in facilitating the construction of an AFC, and identify critical factors that enable intermediary organizations to perform their functions. Research Design and Methods: We conducted three focus groups and one individual interview with multiple interest groups including older adults and social workers from nonprofit organizations and local government involved in a 6-year citywide AFC project in Hong Kong. Participants were asked to share their views on the role of universities in relation to their own experiences and roles in the project. Data generated from the interviews were analyzed using thematic analysis. Results: Four themes pertinent to the functions of universities in facilitating development were identified: facilitating cross-sector collaborations, knowledge diffusion, interest-group building, and mediating divergent interests. We also found that neutrality and reputability are key characteristics for intermediary organizations to wield sufficient legitimacy to perform their functions efficiently. Discussion and Implications: Findings underscore the important yet overlooked role of intermediary organizations in bridging and mediating different interest groups to facilitate AFC development. We advance gerontological scholarship by providing insights into the theoretical mechanisms and practice implications for intermediary organizations in fostering an AFC.

Don't you see the possibilities? Young preschoolers may lack possibility concepts.

Preschoolers struggle to solve problems when they have to consider what might and might not happen. Instead of planning for all open possibilities, they simulate one possibility and treat it as the fact of the matter. Why? Are scientists asking them to solve problems that outstrip their executive capacity? Or do children lack the logical concepts needed to take multiple conflicting possibilities into account? To address this question, task demands were eliminated from an existing measure of children's ability to think about mere possibilities. One hundred nineteen 2.5- to 4.9-year-olds were tested. Participants were highly motivated but could not solve the problem. Bayesian analysis revealed strong evidence that reducing task demands while holding reasoning demands constant did not change performance. Children's struggles with the task cannot be explained by these task demands. Results are consistent with the hypothesis that children struggle because they cannot deploy possibility concepts that allow them to mark representations as merely possible. RESEARCH HIGHLIGHTS: Preschoolers are surprisingly irrational when faced with problems that ask them to consider what might and might not be the case. These irrationalities could arise from deficits in children's logical reasoning capacities or from extraneous task demands. This paper describes three plausible task demands. A new measure is introduced that preserves logical reasoning demands while eliminating all three extraneous task demands. Eliminating these task demands does not change performance. These task demands are not likely a cause of children's irrational behavior.

A developmental investigation of group concepts in the context of social hierarchy: Can the powerful impose group membership?

Group membership is not always voluntary and can be imposed within a social context; moreover, those with power disproportionately shape group membership. We asked if children and adults view group membership as imposed by the powerful. We undertook four studies (465 children ages 4-9, 150 adults): Studies 1-2 used novel minimal groups; Study 3 used 'cool' and 'uncool'; Study 4 used novel ethnic groups. In the first three studies, children saw groups varying in power asserting that a non-categorized individual ought to belong to one of the operating groups in the context. Adults indicated that the declarations of the high-power group (and only the high-power group) made the individual a member of the declared group. Young children rejected that group membership could be imposed. In Study 4, children of all ages reasoned that the high-power group could decide membership for a consenting individual and impose clothing restrictions on a non-consenting individual; unlike adults, children of all ages did not reason the high-power group could impose group membership more frequently than chance. Taken together, adult participants consistently reasoned that group membership was imposed and disproportionately by those with power but children, more often than adults, reasoned that group membership was voluntary.

Having less means wanting more: Children hold an intuitive economic theory of diminishing marginal utility.

Judgments surrounding resource acquisition and valuation are ubiquitous in daily life. How do humans decide what something is worth to themselves or someone else? One important cue to value is that of resource quantity. As described by economists, the principle of diminishing marginal utility (DMU) holds that as resource abundance increases, the value placed on each unit decreases; likewise, when resources become more scarce, the value placed on each unit rises. While prior research suggests that adults make judgments that align with this concept, it is unclear whether children do so. In Study 1 (n = 104), children (ages 5 through 8) were presented with scenarios involving losses or gains to others' resources and predicted the actions and emotions of the individuals involved. Participants made decisions that aligned with DMU, e.g., expecting individuals with fewer resources to expend more effort for an additional resource than individuals with greater resources. In Study 2 (n = 104), children incorporated information about preferences when inferring others' resource valuations, showing how quantity and preference are both included in children's inferences about others' utility. Our results indicate the early emergence of an intuitive economic theory that aligns with an important economic principle. Long before formal learning on this topic, children integrate quantity and preference information to sensibly predict others' resource valuations, with implications for economic decision-making, social preferences, and judgments of partner quality across the lifespan.

Stereotypes as prototypes in children's gender concepts.

How do gender stereotypes shape prototypes across development? In the current pre-registered study with children ages 3- to 10-years-old and adults (N = 257), participants made judgements about which members of gender categories (boys and girls) and animal categories (for comparison) were the most representative and informative about their kinds, using simplified scales of five category members varying on a stereotypical feature (e.g., girls wearing more or less pink). Young children chose boys and girls with extreme stereotypical features (e.g., the girl in head-to-toe pink) as both representative and informative of their categories and this tendency declined with age, similar to developmental patterns in prototypes of animal categories. Controlling for age, children whose parents reported more conservative social-political views also held more extreme gender (but not animal) prototypes. Thus, stereotypes play a central role in children's gender prototypes, especially young children and those living in socially-conservative households. A video abstract of this article can be viewed at https://youtu.be/Ps9BwuukyD0 RESEARCH HIGHLIGHTS: Stereotypes play a central role in children's gender prototypes, especially young children and those in socially-conservative households. Children ages 3-10 and adults chose which girls, boys, and animals were most representative and informative. Younger children chose category members with more extreme stereotypical features (e.g., the girl in head-to-toe pink) than older children and adults. Children with more conservative parents also held more extreme gender prototypes.

Minimal representations of possibility at age 3.

Young children do not always consider alternative possibilities when planning. Suppose a prize is hidden in a single occluded container and another prize is hidden in an occluded pair. If given a chance to choose one container and receive its contents, choosing the singleton maximizes expected reward because each member of the pair might be empty. Yet, 3-y-olds choose a member of the pair almost half the time. Why don't they maximize expected reward? Three studies provide evidence that 3-y-olds do not deploy possibility concepts like MIGHT, which would let them represent that each container in the pair might and might not contain a prize. Rather, they build an overly specific model of the situation that correctly specifies that the singleton holds a prize while inappropriately specifying which member of the pair holds a prize and which is empty. So, when asked to choose a container, they see two equally good options. This predicts approximately 50% choice of the singleton, observed in studies 1 and 3. But when asked to throw away a container so that they can receive the remaining contents (study 2), they mostly throw away a member of the pair. The full pattern of data is expected if children construct overly specific models. We discuss whether 3-year-olds lack possibility concepts or whether performance demands prevent deployment of them in our tasks.

Examining children's questions and parents' responses about COVID-19 pandemic in Turkey.

COVID-19 pandemic has had a significant impact on both adults' and children's everyday lives. Conversations about biological processes such as viruses, illness, and health have started to occur more frequently in daily interactions. Although there are many guidelines for parents about how to talk to their children about the coronavirus, only a few studies have examined what children are curious about the coronavirus and how they make sense of the changes in their everyday lives. This study addresses this need by examining children's questions and parents' responses about the COVID-19 Pandemic in the Turkish sociocultural context. Using an online survey, we asked 184 parents of 3- to 12-year-olds to report their children's questions about coronavirus and their answers to these questions. We analyzed children's questions and parents' responses using qualitative and quantitative analyses (Menendez et al., 2021). Children's questions were mainly about the nature of the virus (34%), followed by lifestyle changes (20%). Older children were more likely to ask about school/work and less likely to ask about lifestyle changes than younger children. Parents responded to children's questions by providing realistic explanations (48%) and reassurance (20%). Only 18% of children's questions were explanation-seeking "why" and "how" questions. Parents were more likely to provide explanations if children's questions were explanation-seeking. Family activities such as playing games and cooking were the most common coping strategies reported by parents (69.2%). The findings have important implications for children's learning about the coronavirus and how adults can support children's learning and help them develop coping strategies in different sociocultural contexts.

Giving, Receiving, and Doing Together: Interorganizational Interactions in Age-Friendly Community Initiatives.

Multi-sectoral collaboration is widely considered essential for age-friendly community change; however, there has been little empirical research to describe the ways in which organizations interact as part of age-friendly community initiatives (AFCIs). We conducted a qualitative descriptive study using data from multiple waves of semi-structured interviews with core teams of eight grant-funded AFCIs in the north-eastern U.S. We employed iterative, inductive coding to systematically describe ways in which AFCI core teams described working with other organizational entities. Findings indicated two overarching themes: (a) helping each other (giving and receiving linking, informational, and instrumental assistance), and (b) doing something together (organizing community events, planning collaborative projects, participating in meetings). We discuss the implications of this characterization for guiding research, evaluation, and policy to optimize AFCI implementation and impact across diverse settings.

Logical word learning: The case of kinship.

We examine the conceptual development of kinship through the lens of program induction. We present a computational model for the acquisition of kinship term concepts, resulting in the first computational model of kinship learning that is closely tied to developmental phenomena. We demonstrate that our model can learn several kinship systems of varying complexity using cross-linguistic data from English, Pukapuka, Turkish, and Yanomamö. More importantly, the behavioral patterns observed in children learning kinship terms, under-extension and over-generalization, fall out naturally from our learning model. We then conducted interviews to simulate realistic learning environments and demonstrate that the characteristic-to-defining shift is a consequence of our learning model in naturalistic contexts containing abstract and concrete features. We use model simulations to understand the influence of logical simplicity and children's learning environment on the order of acquisition of kinship terms, providing novel predictions for the learning trajectories of these words. We conclude with a discussion of how this model framework generalizes beyond kinship terms, as well as a discussion of its limitations.

Counting and the ontogenetic origins of exact equality.

Humans are unique in their capacity to both represent number exactly and to express these representations symbolically. This correlation has prompted debate regarding whether symbolic number systems are necessary to represent large exact number. Previous work addressing this question in innumerate adults and semi-numerate children has been limited by conflicting results and differing methodologies, and has not yielded a clear answer. We address this debate by adapting methods used with innumerate populations (a "set-matching" task) for 3- to 5-year-old US children at varying stages of symbolic number acquisition. In five studies we find that children's ability to match sets exactly is related not simply to knowing the meanings of a few number words, but also to understanding how counting is used to generate sets (i.e., the cardinal principle). However, while children were more likely to match sets after acquiring the cardinal principle, they nevertheless demonstrated failures, compatible with the hypothesis that the ability to reason about exact equality emerges sometime later. These findings provide important data on the origin of exact number concepts, and point to knowledge of a counting system, rather than number language in general, as a key ingredient in the ability to reason about large exact number.

We Know More Than We Ever Learned: Processes Involved in the Accumulation of World Knowledge.

Accumulating information and knowledge is a major task of development. A common assumption is that we build our storehouse of world knowledge, our semantic memory, through direct experience. Although direct experience is involved, to explain fully how we know all that we know, we also must consider processes that allow for integration of information learned in separate yet related episodes of direct learning, as well as inferential processes that operate over integrated representations and permit productive extension of knowledge. In this article, I describe the self-derivation through integration paradigm my colleagues and I developed to model these processes. Using this paradigm, we charted individual and developmental variability throughout childhood and in young adults. Several findings support the contention that the self-derivation through integration paradigm provides a valid model for how we build semantic knowledge, including the observations that performance on the task correlates with and predicts individuals' world knowledge and academic success.

The Substance of Cold: Indonesians' Use of Cold Weather Theory to Explain Everyday Illnesses.

Many people across the world use cold conditions, such as cold air and wet clothes, to explain everyday illness, such as colds and flu. In Indonesia, the concept masuk angin, or "trapped wind," appears to reflect this line of folknatural thinking. Interestingly, Indonesians distinguish masuk angin from the common cold, which is a frequent target for "cold weather" explanations in other cultures. We interviewed Indonesian 8- and 10-year-old children, lay adults, and medical expert adults, about the cause, contagiousness, and treatment of everyday illnesses: the common cold, the flu, and masuk angin. Most Indonesian children, and especially adults, believed that cold and flu are caused by germs and are contagious. In contrast, most children and lay adults (but not experts) attributed masuk angin to cold conditions and viewed it as non-contagious. These findings reveal how folknatural and scientific theories of illness coexist in the minds of Indonesian children and lay adults.

Categories convey prescriptive information across domains and development.

Young children display a pervasive bias to assume that what they observe in the world reflects how things are supposed to be. The current studies examined the nature of this bias by testing whether it reflects a particular form of reasoning about human social behaviors or a more general feature of category representations. Children aged 4 to 9 years and adults (N = 747) evaluated instances of nonconformity among members of novel biological and human social kinds. Children held prescriptive expectations for both animal and human categories; in both cases, they said it was wrong for a category member to engage in category-atypical behavior. These prescriptive judgments about categories depended on the extent to which people saw the pictured individual examples as representative of coherent categories. Thus, early prescriptive judgments appear to rely on the interplay between general conceptual biases and domain-specific beliefs about category structure.

Capturing Death in Animated Films: Can Films Stimulate Parent-Child Conversations about Death?

We present three studies examining death in children's animated films. Study 1 is a content analysis of 49 films. We found that death is often portrayed in films, but many deaths occurred off-screen. Deaths were mostly portrayed in a biologically accurate manner, but some films portrayed biological misconceptions. Study 2 (n = 433) reports on parents' attitudes and parent-child conversations about death in films. Children's questions about death in animated films were similar to their questions about death more generally. Animated films may provide a context for parent-child conversations about death, as parents often watched these films with their children. However, it appeared that few parents took advantage of this opportunity to talk about death with their children.
