A series of experiments investigated the effect of speakers’ language, accent, and race on children’s social preferences. When presented with photographs and voice recordings of novel children, 5-year-old children chose to be friends with native speakers of their native language rather than foreign-language or foreign-accented speakers. These preferences were not exclusively due to the intelligibility of the speech, as children found the accented speech to be comprehensible, and did not make social distinctions between foreign-accented and foreign- (...) class='Hi'>language speakers. Finally, children chose same-race children as friends when the target children were silent, but they chose other-race children with a native accent when accent was pitted against race. A control experiment provided evidence that children’s privileging of accent over race was not due to the relative familiarity of each dimension. The results, discussed in an evolutionary framework, suggest that children preferentially evaluate others along dimensions that distinguished social groups in prehistoric human societies. (shrink)

What leads humans to divide the social world into groups, preferring their own group and disfavoring others? Experiments with infants and young children suggest these tendencies are based on predispo- sitions that emerge early in life and depend, in part, on natural language. Young infants prefer to look at a person who previously spoke their native language. Older infants preferentially accept toys from native-language speakers, and preschool children preferentially select native-language speakers as friends. Variations in accent (...) are sufficient to evoke these social preferences, which are observed in infants before they produce or comprehend speech and are exhibited by children even when they comprehend the foreign-accented speech. Early-developing preferences for native-language speakers may serve as a foundation for later-developing preferences and conflicts among social groups. (shrink)

This chapter argues that human and animal minds indeed depend on a collection of domain-specific, task-specific, and encapsulated cognitive systems: on a set of cognitive ‘modules’ in Fodor's sense. It also argues that human and animal minds are endowed with domain-general, central systems that orchestrate the information delivered by core knowledge systems. The chapter begins by reviewing the literature on spatial reorientation in animals and in young children, arguing that spatial reorientation bears the hallmarks of core knowledge and of modularity. (...) It then considers studies of older children and adults, arguing that human spatial representations change qualitatively over development and show capacities not found in any other species. Finally, it presents two new experiments that investigate the role of emerging spatial language in uniquely human navigation performance. (shrink)

This innovative study posits that myths in general, and Greek theogonic myth in particular, have a latent meaning that is responsible both for the emotional energy inherent in myths, and for the special attraction they have even to those who no longer believe in their literal meaning. Caldwell describes, in clear and comprehensible language, aspects of psychoanalytic theory relevant to the understanding of Greek myth, implementing a psychoanalytic methodology to interpret the Greek myth of origin and succession, particularly as (...) stated in Hesiod's Theogony. In reassessing this work, which tells the story of the world's beginning from unbounded Chaos to the defeat of the Titans, Caldwell addresses several unexplained problems-- why does the world begin with the spontaneous emergence of four uncaused entities, and why in this particular order? Why does Ouranos prevent his children from being born by confining them in their mother's body? Why is Ouranos castrated by his son, and why is Aphrodite born from the severed genitals? Why is it always the youngest son who overthrows his father, the sky-god, and what is the logic of the steps taken by Zeus to prevent the same thing happening to him? Presenting a new definition and analyses of the psychological functions in myth, this new study should appeal to a wide range of classicists, teachers and students of mythology, and those interested in the application of psychoanalytic methods to literature.

Because human languages vary in sound and meaning, children must learn which distinctions their language uses. For speech perception, this learning is selective: initially infants are sensitive to most acoustic distinctions used in any language1–3, and this sensitivity reflects basic properties of the auditory system rather than mechanisms specific to language4–7; however, infants’ sensitivity to non-native sound distinctions declines over the course of the first year8. Here we ask whether a similar process governs learning of word meanings. We investigated (...) the sensitivity of 5-month-old infants in an English-speaking environment to a conceptual distinction that is marked in Korean but not English; that is, the distinction between ‘tight’ and ‘loose’ fit of one object to another9,10. Like adult Korean speakers but unlike adult English speakers, these infants detected this distinction and divided a continuum of motion-into-contact actions into tightand loose-fit categories. Infants’ sensitivity to this distinction is linked to representations of object mechanics11that are shared by non-human animals12–14. Language learning therefore seems to develop by linking linguistic forms to universal, pre-existing representations of sound and meaning. Our research focuses on the crosscutting conceptual distinctions between actions producing loose- and tight-fitting contact relationships (compare left and right columns in Fig. 1a) and actions producing containment versus support relationships (compare first and second rows in Fig. 1a). As early as Korean and English children begin to talk about such actions, they categorize them differently from one another and similarly to Korean- and Englishspeaking adults9,15. Moreover, English and Korean adults differ in their performance on non-linguistic categorization tasks involving heterogeneous examples of these actions, in accord with the differing semantics of their languages16,17, whereas the performance of young children on such tasks has been mixed9,10,18,19..

What did science make possible for colonial rule? How was science in turn marked by the knowledge and practices of those under colonial rule? Here I approach these questions via the social history of Madras Observatory. Constructed in 1791 by the East India Company, the observatory was to provide local time to mariners and served as a clearinghouse for the company’s survey and revenue administration. The astronomical work of Madras’ Brahmin assistants relied upon their knowledge of jyotiśāstra [Sanskrit astronomy/astrology], and (...) can be seen as a specialized form of the kind of South Indian scribal labor and knowledge that also staffed the company’s tax offices. If at Greenwich the division of labor meant observatory work bore resemblances to the factory and the accounts office, in Madras, astronomy and accounting drew on similar labor forms because they were part of the same enterprise. But the company did not just adapt preexisting forms of labor, it also attempted to produce its own at a school built near the observatory to train “half-caste” orphans as apprentice surveyors and assistant computers. The school, staffed by the Brahmins, drew upon knowledge and pedagogical practice associated with the tinnai, the schools in which upper-caste children learned to read, write, and calculate. For a time, the observatory’s social order was literally “half-caste.” The paper also considers how the relationship between caste, status, and instrument was reflected in the visual and material culture of the observatory, such as in Indian-language inscriptions on its central pillar. For company astronomers, the measurement of time meant reworking the relationships among the Indian past, the colonial present, and an imperial posterity. Science under colonial rule spanned multiple temporal and social registers because it was the result of negotiations between the demands of political economy and the knowledge and practices of colonized others.

Abstract Christopher Gauker has argued that a cause?effect analysis of the acquisition of communication skills in chimpanzees is adequate to describe the data reported in our work at the Language Research Center. I agree that the cause?effect approach to language function is the only viable method of analyzing language. Language must be studied as a process that functions to organize behavior between two or more individuals. However, the problem of language understanding is not addressed satisfactorily (...) by the perspective offered by Gauker. Some more recent work, particularly with the pygmy chimpanzee ?Kanzi?, is now beginning to explicate a cause?effect analysis of language comprehension. It is argued that in the young chimpanzee, as with children, language comprehension is the driving force underlying the language acquisition process. It is further argued that the transition from comprehension to production is made possible by the capacity for goal?directed observational imitation. (shrink)

In order for artificial intelligent systems to interact naturally with human users, they need to be able to learn from human instructions when actions should be imitated. Human tutoring will typically consist of action demonstrations accompanied by speech. In the following, the characteristics of human tutoring during action demonstration will be examined. A special focus will be put on the distinction between two kinds of motion events: path-oriented actions and manner-oriented actions. Such a distinction is inspired by the literature pertaining (...) to cognitive linguistics, which indicates that the human conceptual system can distinguish these two distinct types of motion. These two kinds of actions are described in language by more path-oriented or more manner-oriented utterances. In path-oriented utterances, the source, trajectory, or goal is emphasized, whereas in manner-oriented utterances the medium, velocity, or means of motion are highlighted. We examined a video corpus of adult–child interactions comprised of three age groups of children—pre-lexical, early lexical, and lexical—and two different tasks, one emphasizing manner more strongly and one emphasizing path more strongly. We analyzed the language and motion of the caregiver and the gazing behavior of the child to highlight the differences between the tutoring and the acquisition of the manner and path concepts. The results suggest that age is an important factor in the development of these action categories. The analysis of this corpus has also been exploited to develop an intelligent robotic behavior—the tutoring spotter system—able to emulate children's behaviors in a tutoring situation, with the aim of evoking in human subjects a natural and effective behavior in teaching to a robot. The findings related to the development of manner and path concepts have been used to implement new effective feedback strategies in the tutoring spotter system, which should provide improvements in human–robot interaction.

Natural language is full of patterns that appear to fit with general linguistic rules but are ungrammatical. There has been much debate over how children acquire these “linguistic restrictions,” and whether innate language knowledge is needed. Recently, it has been shown that restrictions in language can be learned asymptotically via probabilistic inference using the minimum description length (MDL) principle. Here, we extend the MDL approach to give a simple and practical methodology for estimating how much linguistic data (...) are required to learn a particular linguistic restriction. Our method provides a new research tool, allowing arguments about natural language learnability to be made explicit and quantified for the first time. We apply this method to a range of classic puzzles in language acquisition. We find some linguistic rules appear easily statistically learnable from language experience only, whereas others appear to require additional learning mechanisms (e.g., additional cues or innate constraints).

Children learn their native language by exposure to their linguistic and communicative environment, but apparently without requiring that their mistakes be corrected. Such learning from “positive evidence” has been viewed as raising “logical” problems for language acquisition. In particular, without correction, how is the child to recover from conjecturing an over-general grammar, which will be consistent with any sentence that the child hears? There have been many proposals concerning how this “logical problem” can be dissolved. In this study, (...) we review recent formal results showing that the learner has sufficient data to learn successfully from positive evidence, if it favors the simplest encoding of the linguistic input. Results include the learnability of linguistic prediction, grammaticality judgments, language production, and form-meaning mappings. The simplicity approach can also be “scaled down” to analyze the learnability of specific linguistic constructions, and it is amenable to empirical testing as a framework for describing human language acquisition.

Microethics is about the ethics of everyday clinical practice. The subtle nuances in communication between doctor and patient (the doctor’s choice of words, tone, body language, gestures, etc.) can influence the exercise of the patient’s autonomy. The four models of the doctor- patient/physician-patient relationship (paternalistic, informative, interpretive, deliberative) weigh respect for autonomy and beneficence in varying proportions. Each model may be appropriate in certain circumstances. This article considers these models from the perspective of microethics and the unique dimensions created (...) by the doctor-child-parent relationship. In particular, the article considers the nuances to the autonomy principle created by the child’s developing maturity and the parent’s role as a co-fiduciary of the child’s interests. Ultimately, the deliberative model seems most appropriate to the paediatric setting, since it accommodates the child’s developing maturity in making healthcare-related decisions. This model infuses care into the doctor’s communication with the child and parent. (shrink)

In this article, Peter and Rowland explore the role of implicit statistical learning in syntactic development. It is often accepted that the processes observed in classic implicit learning or statistical learning experiments play an important role in the acquisition of natural language syntax. As Peter and Rowland point out, however, the results from neither research strand can be used to fully explain how children's syntax becomes adult‐like. They propose to address this shortcoming by using the structural priming paradigm.

The relationship of language to cognition, especially in development, is an issue that has occupied philosophers, psychologists, and linguists for centuries. In recent years, the scientific study of sign languages and deaf individuals has greatly enhanced our understanding of deafness, language, and cognition. This Counterpoints volume considers the extent to which the use of sign language might affect the course and character of cognitive development, and presents a variety of viewpoints in this debate. This volume brings the (...) language-thought discussion into a clearer focus, both theoretically and practically, by placing it in the context of children growing up deaf and the influences of having sign language as their primary form of communication. The discussion is also sharpened by having internationally recognized contributors, such as Patricia Siple, Diane Lillo-Martin, and Ruth Campbell, with specialties in varied areas, all converging on a common interest in which each has conducted empirical research. These contributors clarify and challenge the theoretical assumptions that have driven arguments in the language-thought debate for centuries. An introduction by the editors provides a historical overview of the issues as well as a review of empirical findings that have been offered in response to questions about language-thought relations in deaf children. The final chapters are structured in the form of "live" debate, in which each contributor is given the opportunity to respond to the other perspectives presented in this volume. (shrink)

Many social situations require a mental model of the knowledge, beliefs, goals, and intentions of others: a Theory of Mind (ToM). If a person can reason about other people’s beliefs about his own beliefs or intentions, he is demonstrating second-order ToM reasoning. A standard task to test second-order ToM reasoning is the second-order false belief task. A different approach to investigating ToM reasoning is through its application in a strategic game. Another task that is believed to involve the application of (...) second-order ToM is the comprehension of sentences that the hearer can only understand by considering the speaker’s alternatives. In this study we tested 40 children between 8 and 10 years old and 27 adult controls on (adaptations of) the three tasks mentioned above: the false belief task, a strategic game, and a sentence comprehension task. The results show interesting differences between adults and children, between the three tasks, and between this study and previous research. (shrink)

Chest pain is the pain felt in the chest by infants, children and adolescents. In most cases the pain is not associated with the heart. It is mainly recognized by the observance or report of pain by the infant, child or adolescent by reports of distress by parents or care givers. Chest pain is not unusual in children. Lots of children are seen in ambulatory clinics, emergency rooms and hospitals and cardiology clinics. Usually there is a benign cause for the (...) pain for utmost children. Certain patients have conditions that are serious and perhaps life-threatening. Chest pain in pediatric patients needs careful physical examination and a detailed history that would point to the possibility of a serious cause. Researches of pediatric chest pain are scarce. It has been difficult to create evidence-based guidelines for evaluation. In this paper we propose an expert system to help doctors and parents, and care giver in diagnosing chest pain in infants and children. This expert System is design and implemented in SL5 Object language. (shrink)

Background: With the coming of the Industrial Revolution, the levels of pollution grow significantly. This Technological development contributed to the worsening of shortness breath problems in great shape. especially in infants and children. There are many shortness breath diseases that infants and children face in their lives. Shortness of breath is one of a very serious symptom in children and infants and should never be ignored. Objectives: Along these lines, the main goal of this expert system is to help physician (...) in diagnosing and describe some common causes of shortness of breath in infants and children by diagnosing their cases through our expert system. Moreover, this system which we are presenting will give patient the appropriate diagnosis of disease and the treatment required.

SL5 Object Expert System language was utilized for designing and implementing the proposed expert system. Results: The proposed shortness of breath in children and infants diseases diagnosis expert system was estimated by Medical students and they were satisfied with its result. Conclusions: The Proposed expert system is very useful for Respiratory physician, pediatrician, recently graduated physician, and for children's parents with shortness of breath problem. (shrink)

Background: Arthritis is very common but is not well understood. Actually, “arthritis” is not a single disease; it is an informal way of referring to joint pain or joint disease. There are more than 100 different types of arthritis and related conditions. People of all ages, sexes and races can and do have arthritis, and it is the leading cause of disability in America. More than 50 million adults and 300,000 children have some type of arthritis. It is most common (...) among women and occurs more frequently as people get older. Common arthritis joint symptoms include swelling, pain, stiffness and decreased range of motion. Symptoms may come and go. They can be mild, moderate or severe. They may stay about the same for years, but may progress or get worse over time. Severe arthritis can result in chronic pain, inability to do daily activities and make it difficult to walk or climb stairs. Arthritis can cause permanent joint changes. These changes may be visible, such as knobby finger joints, but often the damage can only be seen on X-ray. Some types of arthritis also affect the heart, eyes, lungs, kidneys and skin as well as the joints. Objectives: The main goal of this expert system is to get the appropriate diagnosis of disease and the correct treatment and give the appropriate method of treatment through several tips that concern the disease and how to treat it and we will see it through the application on the expert system. Methods: in this paper the design of the proposed Expert System which was produced to help Orthopedist in diagnosing Arthritis disease through its symptoms such as: pain on pressure in a joint , Inflammation indicated by joint swelling, Stiffness especially in the morning , Loss of flexibility of joint, Limited, joint movement, Deformity of the joints , Weight loss and fatigue , Non-specific fever and Crepitus. The proposed expert system presents an overview about Arthritis disease is given, the cause of diseases is outlined and the treatment of disease whenever possible is given out. SL5 Object Expert System language was used for designing and implementing the proposed expert system. Results: The proposed Arthritis disease diagnosis expert system was evaluated by Orthopedics students and they were satisfied with its performance. Conclusions: The Proposed expert system is very useful for Orthopedist, patients with arthritis and newly graduated Orthopedics students. (shrink)

Behavior analysis, a rapidly growing profession, began with the use and application of conditioning and learning techniques to modify the behavior of children or adults presenting severe management problems, often because of developmental disabilities. Now behavior analysts work in a variety of settings, from clinics and schools to workplaces. Especially since their practice often involves aversive stimuli or punishment, they confront many special ethical challenges. Recently, the Behavior Analysis Certification Board codified a set of ten fundamental ethical guidelines to be (...) followed by all behavior analysts and understood by all students and trainees seeking certification. This book shows readers how to follow the BACB guidelines in action. The authors first describe core ethical principles and then explain each guideline in detail, in easily comprehensible, everyday language. The text is richly illuminated by more than a hundred vivid case scenarios about which the authors pose, and later answer questions for readers. Useful appendices include the BACB Guidelines, an index to them, practice scenarios, and suggested further reading. Practitioners, instructors, supervisors, students, and trainees alike will welcome this invaluable new aid to professional development. (shrink)

Although the language of vocation was born in a religious context, the contributors in this volume demonstrate that it has now taken root within the broad framework of higher education and has become intertwined with a wide range of concerns. This volume makes a compelling case for vocational reflection and discernment in undergraduate education today, arguing that it will encourage faculty and students alike to venture out of their narrow disciplinary specializations and to reflect on larger questions of meaning (...) and purpose. In conversation with a growing range of scholarly resources, these essays advance the cause of vocational reflection and discernment well beyond its occasional mention in general education courses and career placement offices. The book's thirteen contributors all work in higher education, but they do so as biologists and musicians, sociologists and engineers, doctors and lawyers, college presidents and deans, and scholars of history, literature, and business administration. Together, they demonstrate that vocation has an important role to play across the entire range of traditional academic disciplines and applied fields. Regardless of major, all undergraduates need to consider their current and future responsibilities, determine the stories they will live by, and discover resources for addressing the tensions that will inevitably arise among their multiple callings. Vocation across the Academy will help to reframe current debates about the purpose of higher education. It underscores the important role that colleges and universities can play in encouraging students to reflect more deeply on life's most persistent questions and to consider how they might best contribute to the common good.

_The Arachnean and Other Texts _by Fernand Deligny is a collection of writings from the second half of the 1970s. In 1968 Deligny established a “network” for informally taking care of children with autism that was more than a mere site of living: it was a _milieu_ created out of a reflection on the _mode of being_ autistic. What is a space perceived outside of language? What is the form of a movement without perspective or goal? How do we (...) engage with a world that is not our own, a world turned upside down yet truly common, where _acting_ cohabitates with our actions and the _unknown_ with our forms of knowledge? Such is the mythical web of the “Arachnean,” made of lines, holes, traces, enigmas, and questions without answers that demand to see that which cannot be seen. Long before the digital age of social networks, meshworks, and digital webs, Fernand Deligny speaks to us in his own autobiographical and aphoristic manner. For Deligny, his life was always experienced in the form of “the network as a mode of being.”. (shrink)

The feeling thinking talking intervention was designed because early childhood seems to be a prime time for fostering young children's language skills. This intervention involved teaching teachers from N = 28 kindergarten groups in N = 13 German kindergartens language support strategies to be used in everyday conversations with the children in their care. The FTT intervention was evaluated in a business-as-usual control group design with N = 281 children who were individually tested using objective tests on grammar, (...) vocabulary and working memory before and after the FTT intervention, and in a follow-up about one year after T1. After propensity matching was applied, multilevel models demonstrated that the children taught by the intervention group teachers made faster progress in their understanding of sentences, their application of morphological rules, and their memory for sentences when numerous covariates were controlled. Results suggest that complex language processing abilities in young children can be promoted by a teacher-led intervention in early childhood education. Improved language skills will further all children's academic and social success in school. (shrink)

In some sense, and perhaps this is the hallmark of the modern era, all families cope with competing identities. Children may choose high‐demand careers, such as the priesthood or the military, that may well make them seem like strangers to their parents, speaking almost a different language and embracing values and loyalties unknown at home. Grown children can convert to alien religions and live halfway across the world. Children of immigrants assimilate and may not even have a language (...) in common with their grandparents. But in his book Far from the Tree, Solomon focuses on identities that are inborn, although not necessary genetic, so that, while the child is still “in the nest,” he or she is already somehow a changeling. As the title has it, sometimes the apple does fall “far from the tree.”. (shrink)

The dramatic increases in the survival rate of prematurely born, very low birth weight infants (<1500 g) have created concern about the possible sequelae experienced by these children, in terms of both severe problems and less severe learning and behavior problems. The methodological difficulties involved in answering questions about the outcomes of these children, including the choice of appropriate outcome measures, the analysis of individual variation, the problems associated with dropouts, the relevant comparison groups, the importance of survival rate, and (...) the question of correcting for the degree of prematurity, are considered. In spite of the difficulties in interpreting the studies, the research indicates that many premature children have learning disabilities, particularly in the perceptual and visual motor functioning and some aspects of language and reading. In addition, ethical issues related to prematurity are discussed, including parents’ rights, decision-making, and cost and treatment. Finally, some solutions are proposed involving the use of risk indices for the early detection of developmental problems. (shrink)

At 14 months, children appear to struggle to apply their fairly well-developed speech perception abilities to learning similar sounding words (e.g., bih/dih; Stager & Werker, 1997). However, variability in nonphonetic aspects of the training stimuli seems to aid word learning at this age. Extant theories of early word learning cannot account for this benefit of variability. We offer a simple explanation for this range of effects based on associative learning. Simulations suggest that if infants encode both noncontrastive information (e.g., cues (...) to speaker voice) and meaningful linguistic cues (e.g., place of articulation or voicing), then associative learning mechanisms predict these variability effects in early word learning. Crucially, this means that despite the importance of task variables in predicting performance, this body of work shows that phonological categories are still developing at this age, and that the structure of noninformative cues has critical influences on word learning abilities.

We develop an approach to automatically identify the most probable multiword constructions used in children’s utterances, given syntactically annotated utterances from the Brown corpus of CHILDES. The found constructions cover many interesting linguistic phenomena from the language acquisition literature and show a progression from very concrete toward abstract constructions.

Infants learn from adults readily and cooperate with them spontaneously, but how do they select culturally appropriate teachers and collaborators? Building on evidence that children demonstrate social preferences for speakers of their native language, Experiment 1 presented 10- month-old infants with videotaped events in which a native and a foreign speaker introduced two different toys. When given a chance to choose between real exemplars of the objects, infants preferentially chose the toy modeled by the native speaker. In Experiment 2, (...) 2.5-year-old children were presented with the same videotaped native and foreign speakers, and played a game in which they could offer an object to one of two individuals. Children reliably gave to the native speaker. Together, the results suggest that infants and young children are selective social learners and cooperators, and that language provides one basis for this selectivity. (shrink)

The Body–Object Interaction (BOI) variable measures how easily a human body can physically interact with a word's referent (Siakaluk, Pexman, Aguilera, Owen, & Sears, ). A facilitory BOI effect has been observed with adults in language tasks, with faster and more accurate responses for high BOI words (e.g., mask) than for low BOI words (e.g., ship; Wellsby, Siakaluk, Owen, & Pexman, ). We examined the development of this effect in children. Fifty children (aged 6–9 years) and a group of (...) 21 adults completed a word naming task with high and low BOI words. Younger children (aged 6–7 years) did not show a BOI effect, but older children (aged 8–9 years) showed a significant facilitory BOI effect, as did adults. Magnitude of children's BOI effect was related to age as well as reading skills. These results suggest that bodily experience (as measured by the BOI variable) begins to influence visual word recognition behavior by about 8 years of age. (shrink)

Under many circumstances, children and adult rats reorient themselves through a process which operates only on information about the shape of the environment (e.g., Cheng, 1986; Hermer & Spelke, 1996). In contrast, human adults relocate themselves more flexibly, by conjoining geometric and nongeometric information to specify their position (Hermer & Spelke, 1994). The present experiments used a dual-task method to investigate the processes that underlie the flexible conjunction of information. In Experiment 1, subjects reoriented themselves flexibly when they performed no (...) secondary task, but they reoriented themselves like children and adult rats when they engaged in verbal shadowing of continuous speech. In Experiment 2, subjects who engaged in nonverbal shadowing of a continuous rhythm reoriented like nonshadowing subjects, suggesting that the interference effect in Experiment 1 did not stem from general limits on working memory or attention but from processes more specific to language. In further experiments, verbally shadowing subjects detected and remembered both nongeometric information (Experiment 3) and geometric information (Experiments 1, 2, and 4), but they failed to conjoin the two types of information to specify the positions of objects (Experiment 4).

Theory‐of‐mind (ToM) is an integral part of social cognition, but how it develops remains a critical question. There is evidence that children can gain insight into ToM through experience, including language training and explanatory interactions. But this still leaves open the question of how children gain these insights—what processes drive this learning? We propose that analogical comparison is a key mechanism in the development of ToM. In Experiment 1, children were shown true‐ and false‐belief scenarios and prompted to engage (...) in multiple comparisons (e.g., belief vs. world). In Experiments 2a, 2b, and 3, children saw a series of true‐ and false‐belief events, varying in order and in their alignability. Across these experiments, we found that providing support for comparing true‐ and false‐belief scenarios led to increased performance on false‐belief tests. These findings show that analogical comparison can support ToM learning. (shrink)

Numerical magnitude information is assumed to be spatially represented in the form of a mental number line defined with respect to a body-centred, egocentric frame of reference. In this context, spatial language skills such as mastery of verbal descriptions of spatial position have been proposed to be relevant for grasping spatial relations between numerical magnitudes on the mental number line. We examined 4- to 5-year-old’s spatial language skills in tasks that allow responses in egocentric and allocentric frames of (...) reference, as well as their relative understanding of numerical magnitude. In addition, we evaluated influences of children’s absolute understanding of numerical magnitude assessed by their number word comprehension and of their knowledge on numerical sequences. Results indicated that when considering responses that corresponded to the egocentric perspective, children’s spatial language was associated significantly with their relative numerical magnitude understanding, even after controlling for covariates, such as children’s SES, mental rotation skills, and also absolute magnitude understanding or knowledge on numerical sequences. This suggests that the use of egocentric reference frames in spatial language may facilitate spatial representation of numbers along a mental number line and thus seem important for preschoolers’ relative understanding of numerical magnitude.

How many words is a bilingual 2-year-old supposed to know or say in each of her languages? Speech and language therapists or researchers lack the tools to answer this question, because several factors have an impact on bilingual language skills: gender, amount of exposure, mode of acquisition, socio-economic status and the distance between L1 and L2. Unfortunately, these factors are usually studied separately, making it difficult to evaluate their weight on a unique measure of vocabulary. The present study (...) measures the contribution of the following factors to the vocabulary scores of bilingual toddlers: i) gender; ii) sibling ranking; iii) relative amount of exposure to each language; iv) mode of exposure; v) SES; vi) linguistic distance; vii) language spoken between parents. Close to the child’s second birthday, parents of 278 UK-based bilinguals completed successively: a 100-word version of the Oxford-CDI, the CDI in the child’s Additional Language, a family questionnaire, and the Language Exposure Questionnaire. Thirty-six British-English-AL pairs were considered, with languages contrasted on a second-language-learning scale : for example, Dutch and French are close to British-English, while Polish or Cantonese are more distant. Data from the corpus were included in two mixed-effect models, one with the English scores in comprehension as the dependent variable, and the other with production scores. The seven factors listed above were included as predictors. The amount of English exposure was the strongest predictor of comprehension scores = 9.35, p <.005, β = 0.02, t = 3.08, p <.005), followed by the language that parents speak between themselves = 14.94, p <.001, β = 1.37, t = 3.76, p <.0005), linguistic distance = 6.92, p <.01, β = -0.74, t = -2.66, p <.01) and age = 4.86, p <.05, β = 0.55, t = 2.17, p <.05). In production, gender = 13.57, p <.0005, β = -0.91, t = -03.72, p <.0005), amount of exposure to English = 13.57, p <.0005, β = -0.91, t = -03.72, p <.0005), the language that parents speak between themselves = 11.85, p <.005, β = 1.09, t = 3.41, p <.001), and the mother’s occupation = 4.51, p <.05, β = 0.63, t = 2.13, p <.05) were the significant predictors. The more English parents use to address one another, the more English words the child says and understands. This surprising result could be simply explained by the fact that parents who speak English together are also more likely to speak English to their child. The main results of this study is that linguistic distance is a powerful predictor of toddlers’ vocabulary in English, with children learning two close languages growing their vocabulary faster than those learning distant languages.

In many communities around the world, speech to infants and small children has increased mean pitch, increased pitch range, increased vowel duration, and vowel hyper-articulation when compared to speech directed to adults. Some of these IDS and CDS features are also attested in foreigner-directed speech, which has been studied for a smaller range of languages, generally major national languages, spoken by millions of people. We examined vowel acoustics in CDS, conversational ADS, and monologues directed to a foreigner in the Towet (...) dialect of the Papuan language Nungon, spoken by 300 people in a remote region in northeastern Papua New Guinea. Previous work established that Nungon CDS entails optional use of consonant alteration, special nursery vocabulary, and special morphosyntax. This study shows that Nungon CDS to children aged 2;2–3;10 lacks vowel hyper-articulation, but still displays other common prosodic traits of CDS styles around the world: increased mean pitch and pitch range. A developmental effect was also attested, in that speech to 2-year-olds contained vowels that were significantly longer than those in speech to 3-year-olds, which in turn had vowels of similar duration to those in Nungon ADS. We also found that Nungon FDS vowel triangles, measured from monologues primarily directed to a non-native speaker, were significantly larger than those of either CDS or conversational ADS, indicating vowel hyper-articulation. The Nungon pattern may align with the patterns of vowels in Norwegian IDS, CDS, and FDS, where hyper-articulation is found in FDS, but not CDS or IDS. The languages of the New Guinea area constitute 20% of the world's languages, but neither an acoustic comparison of vowels in CDS and ADS, nor an acoustic study of FDS, has previously been completed for any language of New Guinea. The function of an FDS style in a small, closed community like those of much of New Guinea may differ from that in larger societies, since there are very few non-native speakers of Nungon. Thus, this study uses monologues recorded with a foreign researcher as interlocutor to study Nungon FDS. (shrink)

A key motivation for Universal Grammar (UG) is developmental: UG can help children acquire the linguistic knowledge that they do as quickly as they do from the data that's available to them. Some of the most fruitful recent work in language acquisition has combined ideas about different hypothesis space building blocks with domain‐general statistical learning. Statistical learning can then provide a way to help navigate the hypothesis space in order to converge on the correct hypothesis. Reinforcement learning is a (...) principled way to update the probability of a categorical option that's in competition with other categorical options. There are two prominent options for linking theory theoretical representations: the Uniformity of Theta Assignment Hypothesis (UTAH) and the relativized form of that theory, relativized UTAH. The learning strategy of Pearl and Sprouse shares the intuition with subjacency that there's a local structural anomaly when syntactic islands occur. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Crafting Marks Into MeaningsJoseph S. CatalanoIn his fascinating book about the Mayan Code, Michael D. Coe writes, “I challenge any native English speaker to avoid thinking of the word ‘twelve’ when looking at ‘12,’ or an Italian to avoid the utterance ‘dodici’ when going through the same performance.” 1 I accept the challenge, and claim that I have done just that. What shall the reply be—“I should not have (...) done so?” One suspects that linguists confuse theoretical problems about writing and reading with the experience itself.The nature of reading and writing is difficult to understand because on the one hand it seems to involve a complex of conventional marks, but on the other hand these marks seem capable of being understood independently of their relationship to speech or to things. One can claim, of course, that the competent reader works under an illusion: meaning comes to a script through spoken language, through a deep-structured language, through concepts, or through the way the neurons work in the brain. Without denying that the written word enters into many relations, I want to make a case that the history of writing shows that we have crafted marks into meanings and, therefore, that a text is meaningful on the level of the script itself.Before proceeding, I want both to clarify my use of the term “script,” and to give the basic outline of this essay. Studies on writing frequently distinguish among writing systems, scripts, and orthographies. Writing system is the most general of these terms. For example, the alphabet forms one writing system, and Chinese characters another. A script is a particular form of writing system; examples are the Roman alphabetic script and the Greek alphabetic script. An orthography is the way a particular language uses a script; for example, the way the English or [End Page 47] French languages use the Roman alphabetic script. In the concrete, however, there are only orthographies, and without wishing to challenge the traditional distinction, I will frequently interchange script and orthography.The first part of the essay is a discussion of my perspective on writing. My perspective is a substantive part of my case about writing, and I will clarify it at some length. Then I will examine some of the steps that led to our ability to read and write fluently. I will be recommending that in reading histories about writing, we view speech merely as a mediation through which written marks are crafted into meanings. My claim is that every artifact, indeed, every thing, needs to be correctly “read” in order to be used, and that the invention of an elegant system of writing lifts this readability from its specific materiality. For example, to use a fork properly one must be able to read this use in the fork. Language lifts this readability from the matter of the fork, the silver or stainless steel, and makes the readability itself an object.IRecall the last time you were engrossed while reading a novel. Most likely, you were not concerned with questions about the meaning of meaning or the difference between meaning and signification. But did your engaged reading and writing involve an inner speech and, if it did, how did you recognize homonyms, for example the difference between there and their? I suspect that only a small part of our vocabulary is acquired by vocalization. But more importantly, I want to question whether writing must be related to speech to be understood.Frank Smith has persistently questioned the belief that reading must involve vocalizations, and he has criticized the notion that the best way to proceed with reading instruction is by mapping speech onto print. In Understanding Reading, he writes: “Phonics is complicated.... We now know that if we really expect to give children a mastery of phonetics, that we are not talking about a dozen or so rules. We are talking about 166 rules, which will still not account for hundreds of the words they might expect to meet in their early reading.” 2In Reading, he notes: “How is it possible to recognize written words without sounding them out? The answer is that we recognize words in... (shrink)

As children with Down syndrome (DS) typically manifest significant delays in language development, the research has pointed out the predictors of later language skills for this clinical population. The purpose of this study was to systematically explore the evidence for early predictors of language outcomes in infants and toddlers with DS from studies published between 2012 and 2022. After the search, nine studies met the inclusion criteria. The results indicated that maternal educational level, adaptive level of functioning, (...) cognitive function, attention skills, communicative intent of the child, early vocalizations, gestures, baby signs, parents’ translation of their children’s gestures into words, and vocabulary level are significant predictors of language outcomes in children with DS. These findings provide a timely and warranted summary of published work that contributes to current understanding of the development of language and communication in DS. They are therefore useful to researchers, clinicians, and families. (shrink)

To construct their first lexicon, infants must determine the relationship between native phonological variation and the meanings of words. This process is arguably more complex for bilingual learners who are often confronted with phonological conflict: phonological variation that is lexically relevant in one language may be lexically irrelevant in the other. In a series of four experiments, the present study investigated English-Mandarin bilingual infants’ abilities to negotiate phonological conflict introduced by learning both a tone and a non-tone language. (...) In a novel word learning task, bilingual children were tested on their sensitivity to tone variation in English and Mandarin contexts. Their abilities to interpret tone variation in a language-dependent manner were compared to those of monolingual Mandarin learning infants. Results demonstrated that at 12 to 13 months, bilingual infants demonstrated the ability to bind tone to word meanings in Mandarin, but to disregard tone variation when learning new words in English. In contrast, monolingual learners of Mandarin did not show evidence of integrating tones into word meanings in Mandarin at the same age even though they were learning a tone language. However, a tone discrimination paradigm confirmed that monolingual Mandarin learning infants were able to tell these tones apart at 12 to 13 months under a different set of conditions. Later, at 17 to 18 months, monolingual Mandarin learners were able to bind tone variation to word meanings when learning new words. Our findings are discussed in terms of cognitive adaptations associated with bilingualism that may ease the negotiation of phonological conflict and facilitate precocious uptake of certain properties of each language.

Humans possess two nonverbal systems capable of representing numbers, both limited in their representational power: the first one represents numbers in an approximate fashion, and the second one conveys information about small numbers only. Conception of exact large numbers has therefore been thought to arise from the manipulation of exact numerical symbols. Here, we focus on two fundamental properties of the exact numbers as prerequisites to the concept of EXACT NUMBERS : the fact that all numbers can be generated by (...) a successor function and the fact that equality between numbers can be defined in an exact fashion. We discuss some recent findings assessing how speakers of Munduruc (an Amazonian language), and young Western children (3-4 years old) understand these fundamental properties of numbers. (shrink)
