Religious polarization and justification of belief in invisible scientific versus religious entities

Children and adults express greater confidence in the existence of invisible scientific as compared to invisible religious entities. To further examine this differential confidence, 5- to 11-year-old Turkish children and their parents (N = 174, 122 females) from various regions in Türkiye, a country with an ongoing tension between secularism and religion, were tested in 2021 for their belief in invisible entities. Participants expressed more confidence in the existence of scientific than religious entities. For scientific entities, children justified their belief primarily by elaborating on the properties of the entity, rather than referring to the testimonial source of their judgment. This pattern was reversed for religious entities, arguably, highlighting the role of polarization in shaping the testimony children typically hear.

How does caregiver-child conversation during a scientific storybook reading impact children's mindset beliefs and persistence?

This study explores how caregiver-child scientific conversation during storybook reading focusing on the challenges or achievements of famous female scientists impacts preschoolers' mindset, beliefs about success, and persistence. Caregiver-child dyads (N = 202, 100 female, 35% non-White, aged 4-5, ƒ = .15) were assigned to one of three storybook conditions, highlighting the female scientist's achievements, effort, or, in a baseline condition, neither. Children were asked about their mindset, presented with a persistence task, and asked about their understanding of effort and success. Findings demonstrate that storybooks highlighting effort are associated with growth mindset, attribution of success to hard work, and increased persistence. Caregiver language echoed language from the assigned storybook, showing the importance of reading storybooks emphasizing hard work.

The development and diversity of religious cognition and behavior: Protocol for Wave 1 data collection with children and parents by the Developing Belief Network

The Developing Belief Network is a consortium of researchers studying human development in diverse social-cultural settings, with a focus on the interplay between general cognitive development and culturally specific processes of socialization and cultural transmission in early and middle childhood. The current manuscript describes the study protocol for the network's first wave of data collection, which aims to explore the development and diversity of religious cognition and behavior. This work is guided by three key research questions: (1) How do children represent and reason about religious and supernatural agents? (2) How do children represent and reason about religion as an aspect of social identity? (3) How are religious and supernatural beliefs transmitted within and between generations? The protocol is designed to address these questions via a set of nine tasks for children between the ages of 4 and 10 years, a comprehensive survey completed by their parents/caregivers, and a task designed to elicit conversations between children and caregivers. This study is being conducted in 39 distinct cultural-religious groups (to date), spanning 17 countries and 13 languages. In this manuscript, we provide detailed descriptions of all elements of this study protocol, give a brief overview of the ways in which this protocol has been adapted for use in diverse religious communities, and present the final, English-language study materials for 6 of the 39 cultural-religious groups who are currently being recruited for this study: Protestant Americans, Catholic Americans, American members of the Church of Jesus Christ of Latter-day Saints, Jewish Americans, Muslim Americans, and religiously unaffiliated Americans.

Children's beliefs in invisible causal agents-Both religious and scientific

Against the proposal that children have a natural disposition for supernatural or religious beliefs, we review the decades-old evidence showing that children typically invoke naturalistic causes-even in the face of unusual outcomes. Instead, we propose that children's tendency to endorse supernatural agents reflects their capacity for cultural learning rather than an inherent inclination to believe in divine powers. We support this argument by reviewing the findings that religious exposure in childhood, not individual cognitive or personality factors, is the major determinant of religiosity in adulthood. We highlight the role of cultural learning in children's endorsement of invisible divine agents by drawing on cross-cultural evidence that children are equally receptive to claims regarding the existence of invisible natural agents. We end by introducing a hypothesis to explain how children come to endorse religious beliefs despite their bias toward naturalistic explanation.

Expressions of uncertainty in invisible scientific and religious phenomena during naturalistic conversation

Across cultures, studies report more confidence in the existence of unobservable scientific phenomena, such as germs, as compared to unobservable religious phenomena, such as angels. We investigated a potential cultural mechanism for the transmission of confidence in the existence of invisible entities. Specifically, we asked whether parents in societies with markedly different religious profiles-Iran and China-signal differential confidence across the domains of science and religion during unmoderated conversations with their children (N = 120 parent-child dyads in total; 5- to 11-year-olds). The results revealed that parents used fewer lexical cues to uncertainty when discussing scientific phenomena, as compared to religious phenomena. Unsurprisingly, this cross-domain distinction was observed among majority belief, secular parents in China (Study 2). More importantly, however, the same pattern was observed among parents in Iran, a highly religious society (Study 1), as well as among minority belief, religious parents in China (Study 2). Thus, adults in markedly different belief communities spontaneously express less confidence in religious, as compared to scientific, invisible entities in naturalistic conversation. These findings contribute to theories on the role of culture and testimony in the development of beliefs about unobservable phenomena.

Social robots as social learning partners: Exploring children's early understanding and learning from social robots

Clark and Fischer propose that people interpret social robots not as social agents, but as interactive depictions. Drawing on research focusing on how children selectively learn from social others, we argue that children do not view social robots as interactive toys but instead treat them as social learning partners and critical sources of information.

The impact of visualizing the group on children's persistence in and perceptions of STEM

Women are underrepresented in STEM fields across the world. We investigate a perceptual mechanism that may contribute to this gender disparity beginning in early childhood. We explore how visual information about the gender composition of a group of scientists impacts children's persistence on a STEM task and their evaluations of group members. One hundred sixty-six 4- to 6-year-old children viewed one of four groups of scientists: all-male, all-female, a lone female among all-males, or a lone male among all-females. Whereas children's persistence on a STEM task did not change across conditions, their trait judgments did. Children judged the all-male and all-female group scientists as "hardworking," but judged the lone female scientist as "smart." However, they were as likely to judge the lone male scientist as "smart" as to judge him "hardworking." The role of group visualization as a learning mechanism impacting children's perceptions of scientists as early as the preschool years is discussed.

What would happen if?: A comparison of fathers' and mothers' questions to children during a science activity

Parents' questions are an effective strategy for fostering the development of young children's science understanding and discourse. However, this work has not yet distinguished whether the frequency of questions about scientific content differs between mothers and fathers, despite some evidence from other contexts (i.e., book reading) showing that fathers ask more questions than mothers. The current study compared fathers' and mothers' questions to their four- to six-year-old children (N = 49) while interacting with scientific stimuli at a museum research exhibit. Results indicated that fathers asked significantly more questions than mothers, and fathers' questions were more strongly related to children's scientific discourse. Results are discussed in terms of the importance of adult questions for the development of children's scientific understanding as well as broadening research to include interlocutors other than mothers.

Belief, culture, & development: Insights from studying the development of religious beliefs and behaviors

We describe the theoretical and methodological contributions of a cultural and developmental approach to the study of religious belief and behavior. We focus on how the study of religious development can provide a foothold into answering some key questions in developmental science: What is belief? What is culture? What is the nature of human development? Throughout the chapter, we provide examples of methodological innovations that have emerged over the course of the first year of a global, collaborative research project into the development of religious beliefs and behaviors.

What could have been done? Counterfactual alternatives to negative outcomes generated by religious and secular children

Recent research has shown that a religious upbringing renders children receptive to ordinarily impossible outcomes, but the underlying mechanism for this effect remains unclear. Exposure to religious teachings might alter children's basic understanding of causality. Alternatively, religious exposure might only affect children's religious cognition, not their causal judgments more generally. To test between these possibilities, 6- to 11-year-old children attending either secular (n = 49, 51% female, primarily White and middle-class) or parochial schools (n = 42, 48% female, primarily White and middle-class) heard stories in which characters experienced negative outcomes and indicated how those characters could have prevented them. Both groups of children spontaneously invoked interventions consistent with natural causal laws. Similarly, when judging the plausibility of several counterfactual interventions, participants endorsed the intervention consistent with natural laws at high levels, irrespective of schooling. However, children's endorsement of supernatural interventions inconsistent with these laws revealed both group similarities and differences. Although both groups of children judged divine intervention (i.e., via prayer) as more plausible than mental (i.e., via wishing) and magical (i.e., via magical powers) interventions, children receiving religious (vs. secular) schooling were more likely to do so. Moreover, although children with a secular upbringing overwhelmingly chose naturalistic interventions as the most effective, children with a religious upbringing chose divine as well as naturalistic intervention. These results indicate that religious teaching does not alter children's basic understanding of causality but rather adds divine intervention to their repertoire of possible causal factors.

Children's Ideas About What Can Really Happen: The Impact of Age and Religious Background

Five- to 11-year-old U.S. children, from either a religious or secular background, judged whether story events could really happen. There were four different types of stories: magical stories violating ordinary causal regularities; religious stories also violating ordinary causal regularities but via a divine agent; unusual stories not violating ordinary causal regularities but with an improbable event; and realistic stories not violating ordinary causal regularities and with no improbable event. Overall, children were less likely to judge that religious and magical stories could really happen than unusual and realistic stories although religious children were more likely than secular children to judge that religious stories could really happen. Irrespective of background, children frequently invoked causal regularities in justifying their judgments. Thus, in justifying their conclusion that a story could really happen, children often invoked a causal regularity, whereas in justifying their conclusion that a story could not really happen, they often pointed to the violation of causal regularity. Overall, the findings show that children appraise the likelihood of story events actually happening in light of their beliefs about causal regularities. A religious upbringing does not impact the frequency with which children invoke causal regularities in judging what can happen, even if it does impact the type of causal factors that children endorse.

If I told you everyone picked that (non-affordant) tool, would you? Children attend to conventional language when imitating and transmitting tool use

This study explored how conventional versus instrumental language influenced children's imitation and transmission of non-affordant tool use. Rather than examining children's imitation of unnecessary actions that do not impede goal completion, we examined children's conformity with a modeled behavior that may result in sacrificing goal completion. Children (N = 96 4- to 6-year-olds) were presented with either a conventional or instrumental description of a model's actions before watching the model choose a non-affordant tool. Children who heard conventional language imitated and transmitted the model's non-affordant tool choice at significantly higher rates than when they heard instrumental language. The results have implications for children, parents, and teachers regarding the extent to which children will conform with what "we" are "supposed" to do.

Children's developing capacity to calibrate the verbal testimony of others with observed evidence when inferring causal relations

Across two studies (N = 120), we investigated the development of children's ability to calibrate the certainty of verbal testimony with observable data that varied in the degree of predictive causal accuracy. In Study 1, 4- and 5-year-olds heard a certain explanation or an uncertain explanation about deterministic causal relations. The 5-year-olds made more accurate causal inferences when the informant provided a certain and more calibrated explanation. In Study 2, children heard similar explanations about probabilistic relations, making the uncertain informant more calibrated. The 5-year-olds were more likely to infer the correct causal relations when the informant was uncertain, but only when the explanation was attuned to the stochasticity of the individual causal events (or outcomes that sometimes occur). These findings imply that the capacity to integrate, and make efficient inferences, from distinct sources of knowledge emerges during the preschool years.

Parents’ Beliefs about Their Influence on Children’s Scientific and Religious Views: Perspectives from Iran, China and the United States

Parents in Iran, China and the United States were asked 1) about their potential influence on their children’s religious and scientific views and 2) to consider a situation in which their children expressed dissent. Iranian and US parents endorsed their influence on the children’s beliefs in the two domains. By contrast, Chinese parents claimed more influence in the domain of science than religion. Most parents spoke of influencing their children via Parent-only mechanisms in each domain (e.g., discussion, teaching), although US parents did spontaneously note Multiple sources for the transmission of religious views (e.g., church, other influential adults). Parents proposed a similar stance towards children’s dissenting religious and scientific views. Chinese and US parents were more likely to express Supportive approaches and Iranian parents were more likely to express a Directive approach by comparison. The present research informs our understanding of the cultural transmission of views about science and religion.

Beliefs of children and adults in religious and scientific phenomena

Within the domains of both science and religion, beliefs in unobservable phenomena - such as bacteria or the soul - are common. Yet given the radically different trajectory of scientific as compared to religious beliefs across human history, it is plausible that the psychological basis for beliefs in these two domains is also different. Indeed, there is evidence from children and adults in various cultures that people have greater confidence in their scientific beliefs than in their religious beliefs. However, when individuals are invited to indicate the basis for their beliefs within each domain, a surprisingly similar pattern of justification is apparent.

Investigating Science Together: Inquiry-Based Training Promotes Scientific Conversations in Parent-Child Interactions

This study examined the effects of two pedagogical training approaches on parent-child dyads’ discussion of scientific content in an informal museum setting. Forty-seven children (mean age = 5.43) and their parents were randomly assigned to training conditions where an experimenter modeled one of two different pedagogical approaches when interacting with the child and a science-based activity: (1) a scientific inquiry-based process or (2) a scientific statement-sharing method. Both approaches provided the same information about scientific mechanisms but differed in the process through which that content was delivered. Immediately following the training, parents were invited to model the same approach with their child with a novel science-based activity. Results indicated significant differences in the process through which parents prompted discussion of the targeted information content: when talking about causal scientific concepts, parents in the scientific inquiry condition were significantly more likely to pose questions to their child than parents in the scientific statements condition. Moreover, children in the scientific inquiry condition were marginally more responsive to parental causal talk and provided significantly more scientific content in response. These findings provide initial evidence that training parents to guide their children using scientific inquiry-based approaches in informal learning settings can encourage children to participate in more joint scientific conversations.

Embedding Scientific Explanations Into Storybooks Impacts Children's Scientific Discourse and Learning

Children’s understanding of unobservable scientific entities largely depends on testimony from others, especially through parental explanations that highlight the mechanism underlying a scientific entity. Mechanistic explanations are particularly helpful in promoting children’s conceptual understanding, yet they are relatively rare in parent–child conversations. The current study aimed to increase parent–child use of mechanistic conversation by modeling this language in a storybook about the mechanism of electrical circuits. We also examined whether an increase in mechanistic conversation was associated with science learning outcomes, measured at both the dyadic- and child-level. In the current study, parents and their 4- to 5-year-old children (N = 60) were randomly assigned to read a book containing mechanistic explanations (n = 32) or one containing non-mechanistic explanations (n = 28). After reading the book together, parent–child joint understanding of electricity’s mechanism was tested by asking the dyad to assemble electrical components of a circuit toy so that a light would turn on. Finally, child science learning outcomes were examined by asking children to assemble a novel circuit toy and answer comprehension questions to gauge their understanding of electricity’s mechanism. Results indicate that dyads who read storybooks containing mechanistic explanations were (1) more successful at completing the circuit (putting the pieces together to make the light turn on) and (2) used more mechanistic language than dyads assigned to the non-mechanistic condition. Children in the mechanistic condition also had better learning outcomes, but only if they engaged in more mechanistic discourse with their parent. We discuss these results using a social interactionist framework to highlight the role of input and interaction for learning. We also highlight how these results implicate everyday routines such as book reading in supporting children’s scientific discourse and understanding.

Epistemic justifications for belief in the unobservable: The impact of minority status

Children hold beliefs about religious and scientific entities, such as angels or germs, that they cannot directly observe or interact with. Given their limited opportunities for first-hand observation, children's beliefs in these entities are a clear example of cultural learning and are likely to vary based on cultural factors. In the present study, we investigated variation in the epistemic stance of 4-11-year-old children growing up in a religious minority in China (N = 47), a religious majority in Iran (N = 85), and a religious majority in the U.S. (N = 74). To assess the role of community status as a domain-specific, as opposed to a domain-general, factor contributing to children's beliefs about unobservable entities, we compared children's beliefs about religious unobservable entities with their beliefs about scientific unobservable entities in these three communities. In all three communities, younger and older children were confident that unobservable religious and scientific entities exist. However, compared to children in Iran and the U.S., children from the religious minority group in China were more likely to justify their ontological beliefs about religious entities by appealing to the source of their beliefs. These results highlight the impact of community status on learning from testimony about unobservable entities. Additionally, the results show that under certain circumstances - notably when holding minority beliefs - tracking the source of beliefs serves as a central epistemic justification.

Conflicting perspectives mediate the relation between parents' and preschoolers' self-referent mental state talk during collaboration

We examined the relations between the referent of parents and preschoolers' mental state talk during a collaborative puzzle-solving task (N = 146 dyads; n = 81 3-year-olds, n = 65 4-year-olds). The results showed that parents' references to their own knowledge and beliefs (self-referent cognitive talk), and references to their child's knowledge and beliefs (child-referent cognitive talk) were both related to children's (primarily self-referent) cognitive talk. We then tested whether any of the observed relations could be explained by the presence of conflicting perspectives within the collaborative interaction. Mediational analyses revealed that conflicting perspectives mediated the positive relation between parents' production of self-referent cognitive talk and child cognitive talk. By contrast, the positive relation between parents' production of child-referent cognitive talk and child cognitive talk did not depend on the presence of this type of conflict. These findings highlight an important mechanism through which parents' references to their own mind might promote children's developing mental state talk in collaborative contexts.

I don't believe what you said before: Preschoolers retrospectively discount information from inaccurate speakers

Children use speakers' past accuracy to make inferences about novel word meanings those individuals provide in the future. An open question is whether children can retrospectively reevaluate information after learning that the source was inaccurate. We addressed this question in two experiments where a speaker first introduced labels for novel objects and then revealed that she is either accurate or inaccurate in naming familiar objects. Experiment 1 showed that 3.5- to 6.5-year-olds displayed enhanced performance on a word knowledge test when they had learned novel words from a speaker who then showed herself to be an accurate labeler as opposed to an inaccurate labeler. Experiment 2 replicated this procedure but had a different speaker provide inaccurate label information. This manipulation did not affect learning, suggesting that children discount speakers and are not simply influenced by the demands of processing inaccurate information. Together, these results indicate that 3.5- to 6.5-year-olds continue to monitor the speakers' accuracy after learning new words from them, update their beliefs as accuracy data become available, and selectively retain words learned from speakers who they deem to be epistemically competent.

On the malleability of selective trust

Although much research has explored the cues that young children use to determine informant credibility, little research has examined whether credibility judgments can change over time as a function of children's language environment. This study explored whether changes in the syntactic complexity of adults' testimony shifts 4- and 5-year-old children's (N = 42) credibility and learning judgments. Children from lower-socioeconomic status (SES) backgrounds were randomly assigned to hear a high proportion of complex language (the passive voice) or simpler language (the active voice) during 10 days of book-reading interactions with adult experimenters. Before and after the book-reading sessions, children's learning preferences for informants who used passive versus active voice were measured. Exposure to the complex passive voice led children to use syntactic complexity as a cue to make inferences about who to learn from, whereas active voice exposure resulted in no such shift. Implications for the role of the language environment in children's selective trust are discussed.

Beliefs About Religious and Scientific Entities Among Parents and Children in Iran

Previous research has shown that children and adults express more confidence in the existence of unobservable scientific (e.g., germs), as compared to religious, phenomena (e.g., the soul). We asked if the same pattern would emerge among parents ( N = 77) and children ( N = 85) in Iran, a country with widespread commitment to religious values and beliefs. Parents expressed confidence in the existence of various scientific and religious phenomena but were more confident that scientific phenomena exist. Moreover, even though Iranian parents expressed a high valuation of both science and religion, their valuation of science was higher than that of religion. Like their parents, older children also expressed greater confidence in the existence of scientific, as compared to religious, phenomena. We conclude that with age, the kind of discourse children are exposed to elicits more confidence in the existence of scientific phenomena even in a religious society.

The Theoretical and Methodological Opportunities Afforded by Guided Play With Young Children

For infants and young children, learning takes place all the time and everywhere. How children learn best both in and out of school has been a long-standing topic of debate in education, cognitive development, and cognitive science. Recently, guided play has been proposed as an integrative approach for thinking about learning as a child-led, adult-assisted playful activity. The interactive and dynamic nature of guided play presents theoretical and methodological challenges and opportunities. Drawing upon research from multiple disciplines, we discuss the integration of cutting-edge computational modeling and data science tools to address some of these challenges, and highlight avenues toward an empirically grounded, computationally precise and ecologically valid framework of guided play in early education.

Cognitive Foundations of Learning from Testimony

Humans acquire much of their knowledge from the testimony of other people. An understanding of the way that information can be conveyed via gesture and vocalization is present in infancy. Thus, infants seek information from well-informed interlocutors, supply information to the ignorant, and make sense of communicative acts that they observe from a third-party perspective. This basic understanding is refined in the course of development. As they age, children's reasoning about testimony increasingly reflects an ability not just to detect imperfect or inaccurate claims but also to assess what inferences may or may not be drawn about informants given their particular situation. Children also attend to the broader characteristics of particular informants-their group membership, personality characteristics, and agreement or disagreement with other potential informants. When presented with unexpected or counterintuitive testimony, children are prone to set aside their own prior convictions, but they may sometimes defer to informants for inherently social reasons.

Preschoolers' Preference for Syntactic Complexity Varies by Socioeconomic Status

Two experiments investigated whether 4- and 5-year-old children choose to learn from informants who use more complex syntax (passive voice) over informants using more simple syntax (active voice). In Experiment 1 (N = 30), children viewed one informant who consistently used the passive voice and another who used active voice. When learning novel words from the two informants, children were more likely to endorse information from the passive informant. Experiment 2 (N = 32) explored whether preference for the passive informant varied by socioeconomic status (SES; eligibility for free/reduced lunch). Although higher SES children selectively preferred the passive informant, lower SES children preferred the active informant. Explanations are discussed for why SES might moderate children's sensitivity to syntactic complexity when choosing from whom to learn.

Monoracial and biracial children: effects of racial identity saliency on social learning and social preferences

Children prefer learning from, and affiliating with, their racial in-group but those preferences may vary for biracial children. Monoracial (White, Black, Asian) and biracial (Black/White, Asian/White) children (N = 246, 3-8 years) had their racial identity primed. In a learning preferences task, participants determined the function of a novel object after watching adults (White, Black, and Asian) demonstrate its uses. In the social preferences task, participants saw pairs of children (White, Black, and Asian) and chose with whom they most wanted to socially affiliate. Biracial children showed flexibility in racial identification during learning and social tasks. However, minority-primed biracial children were not more likely than monoracial minorities to socially affiliate with primed racial in-group members, indicating their in-group preferences are contextually based.

Judgments about fact and fiction by children from religious and nonreligious backgrounds

In two studies, 5- and 6-year-old children were questioned about the status of the protagonist embedded in three different types of stories. In realistic stories that only included ordinary events, all children, irrespective of family background and schooling, claimed that the protagonist was a real person. In religious stories that included ordinarily impossible events brought about by divine intervention, claims about the status of the protagonist varied sharply with exposure to religion. Children who went to church or were enrolled in a parochial school, or both, judged the protagonist in religious stories to be a real person, whereas secular children with no such exposure to religion judged the protagonist in religious stories to be fictional. Children's upbringing was also related to their judgment about the protagonist in fantastical stories that included ordinarily impossible events whether brought about by magic (Study 1) or without reference to magic (Study 2). Secular children were more likely than religious children to judge the protagonist in such fantastical stories to be fictional. The results suggest that exposure to religious ideas has a powerful impact on children's differentiation between reality and fiction, not just for religious stories but also for fantastical stories.

To the letter: early readers trust print-based over oral instructions to guide their actions

Children have many opportunities to learn from others through oral and written sources. Recent evidence suggests that early readers place more trust in written over oral testimony when learning names for unfamiliar objects. Across three studies, we examined whether the authority of print extends beyond mere naming to guide children's actions in the physical world. In Study 1, 3- to 6-year-olds received conflicting oral and print-based advice from two puppets about how to operate a novel apparatus. Whereas pre-readers were indiscriminate in their trust, early readers preferred to follow the print-based advice. In Study 2, we replicated this finding, controlling for the amount of corroborating evidence presented by both sources, and the location of the print. In Study 3, we explored whether readers' preference for print-based information was due to a global preference for external representations, or a more specific preference for text. Children were presented with conflicting instructions based on text versus a coloured circle. Whereas pre-readers preferred to follow the colour circle, readers preferred to follow the text. Together, the results suggest that when children learn to read, they rapidly come to regard the written word as a particularly authoritative source of information about how to act in the world.

"Why does rain fall?": children prefer to learn from an informant who uses noncircular explanations

These two studies explored 3- and 5-year-olds' evaluation of noncircular and circular explanations, and their use of such explanations to determine informant credibility. Although 5-year-olds demonstrated a selective preference for noncircular over circular explanations (Experiment 1: Long Explanations; Experiment 2: Short Explanations), 3-year-olds only demonstrated a preference for the noncircular when the explanations were shortened (Experiment 2). Children's evaluation of the explanations extended to their inferences about the informants' future credibility. Both age groups demonstrated a selective preference for learning novel explanations from an informant who had previously provided noncircular explanations-although only 5-year-olds also preferred to learn novel labels from her. The implications and scope of children's ability to monitor the quality of an informant's explanation are discussed.

The good, the strong, and the accurate: preschoolers' evaluations of informant attributes

Much recent evidence shows that preschoolers are sensitive to the accuracy of an informant. Faced with two informants, one of whom names familiar objects accurately and the other inaccurately, preschoolers subsequently prefer to learn the names and functions of unfamiliar objects from the more accurate informant. This study examined the inference process underlying this preference. We asked whether preschoolers make narrow inferences about informants, broader trait-based inferences, or more global evaluative inferences. We further asked what inferences preschoolers make about a potential informant based on distinctions in the unrelated domain of physical strength. The results indicate that preschoolers make relatively narrow inferences when observing individual differences in accuracy even though they are prone to global evaluative inferences when observing individual differences in strength. Preschoolers' burgeoning understanding of others as expert language users may underlie their selective endorsement of a more accurate informant.

Young children's selective trust in informants

Young children readily act on information from adults, setting aside their own prior convictions and even continuing to trust informants who make claims that are manifestly false. Such credulity is consistent with a long-standing philosophical and scientific conception of young children as prone to indiscriminate trust. Against this conception, we argue that children trust some informants more than others. In particular, they use two major heuristics. First, they keep track of the history of potential informants. Faced with conflicting claims, they endorse claims made by someone who has provided reliable care or reliable information in the past. Second, they monitor the cultural standing of potential informants. Faced with conflicting claims, children endorse claims made by someone who belongs to a consensus and whose behaviour abides by, rather than deviating from, the norms of their group. The first heuristic is likely to promote receptivity to information offered by familiar caregivers, whereas the second heuristic is likely to promote a broader receptivity to informants from the same culture.

Preschoolers trust particular informants when learning new names and new morphological forms

Across three studies, we investigated whether 4-year-olds would trust a previously reliable informant when learning novel morphological forms. In Experiment 1, children (N= 16) were presented with two informants: one who correctly named familiar objects and another who named them incorrectly. Children were invited to turn to these informants when learning novel labels and morphological forms. The majority of children chose the previously correct labeller when learning novel label and morphology. In Experiment 2, children (N= 16) were presented with an informant who used familiar plurals correctly and one who used them incorrectly. Children chose the previously correct morphologist when learning novel labels and past tense forms. Thus, children track both semantic and morphological accuracy. In Experiment 3, some children (N= 16) were presented with two informants who differed in naming accuracy, whereas others (N= 16) were presented with two informants who differed in morphological accuracy. To forestall any risk of experimenter cuing, one experimenter blind to the training children had received, tested children with novel labels and morphology. The results replicated those of Experiments 1 and 2. Implications for how children's trust in an informant might play a role in their acquisition of morphological forms are discussed.

Auditory processing and early literacy skills in a preschool and kindergarten population

Although the relationship between auditory processing and reading-related skills has been investigated in school-age populations and in prospective studies of infants, understanding of the relationship between these variables in the period immediately preceding formal reading instruction is sparse. In this cross-sectional study, auditory processing, phonological awareness, early literacy skills, and general ability were assessed in a mixed sample of 88 three- to six-year-old children both cross-sectionally and longitudinally. Results from both cross-sectional and longitudinal analyses suggest the importance of early auditory rise time sensitivity in developing phonological awareness skills, especially in the development of rhyme awareness.
