A fundamental goal of linguistic theory is to explain how natural languages are acquired. This paper describes some recent findings on how learners acquire syntactic knowledge for which there is little, if any, decisive evidence from the environment. The first section presents several general observations about language acquisition that linguistic theory has tried to explain and discusses the thesis that certain linguistic properties are innate because they appear universally and in the absence of corresponding experience. A third diagnostic for innateness, (...) early emergence, is the focus of the second section of the paper, in which linguistic theory is tested against recent experimental evidence on children's acquisition of syntax.

This study examined patterns of auxiliary provision and omission for the auxiliaries BE and HAVE in a longitudinal data set from 11 children between the ages of two and three years. Four possible explanations for auxiliary omission—a lack of lexical knowledge, performance limitations in production, the Optional Infinitive hypothesis, and patterns of auxiliary use in the input—were examined. The data suggest that although none of these accounts provides a full explanation for the pattern of auxiliary use and nonuse observed in (...) children's early speech, integrating input-based and lexical learning-based accounts of early language acquisition within a constructivist approach appears to provide a possible framework in which to understand the patterns of auxiliary use found in the children's speech. The implications of these findings for models of children's early language acquisition are discussed. (shrink)

L’acquisition des pronoms chez les enfants à développement langagier typique est complexe car elle combine de nombreux paramètres, notamment une capacité d’abstraction. Dans une première partie, ces paramètres sont décrits en rapport avec les trajectoires d’apprentissage mises en évidence par la littérature. La seconde partie est consacrée aux difficultés que pose l’acquisition des pronoms chez des enfants à développement langagier atypique, pour des raisons de troubles spécifiques du langage ou de surdité profonde.

It has been argued that the primary acquisition of genericity in early child speech poses a problem for standard quantificational approaches to generics and instead motivates the claim that generics give voice to an innate, default mode of generalising. This article argues that analogous puzzles involving the acquisition of A‐quantifiers undermine the empirical support for a purely cognition‐based approach to generics. Instead, these acquisition puzzles should be solved by generalising the core insight of the cognitive defaults theory to these expressions, (...) reconciling formal semantic approaches with the role that cognitive development plays on lexical competence.

Three proposals are made regarding values acquisition in schools. It is believed that: (a) optimal conditions for the integration of values into school-students' lives will include students' voluntary commitments; (b) values learning must lead to personally transformed relationships between students and topics considered worthwhile; (c) since values learning is, arguably, the core of formal education, there has to be some consistency between what is learned and the wider socio-political scene. It is argued that these conditions are hard to fulfil via (...) the prescribed, performance-oriented curricula currently on offer in English school classrooms. (shrink)

In Pitjantjatjara, a central Australian Indigenous language, speakers typically describe sequences of actions using clause chaining constructions. While similar constructions are common among the world’s languages, very little is known about how children acquire them. A notable exception are the converb constructions of Turkish, which have been relatively well-studied. The present paper examines the acquisition of Pitjantjatara clause chaining constructions and compares this with the acquisition of Turkish converb constructions. Data is drawn from a naturalistic corpus recorded between 2016 and (...) 2019. The corpus contains over 4000 utterances from 23 children aged between 10 months and 10 years, five of whom are recorded at multiple ages. The corpus also includes approximately 1600 utterances from 21 adults, aged between 16 and 70. Results show that the acquisition of Pitjantjatjara clause chains consists of three stages. Stage 1 features juxtaposition of finite verb forms. In Stage 2, children make regular use of clause chain morphology, but primarily for modification purposes. In Stage 3, clause chains are the preferred strategy for sequential actions as well as modification purposes. The initial use of verb juxtaposition followed by increasing use of dedicated morphology is consistent with findings for Turkish converb acquisition, with speakers of both languages utilizing dedicated forms from around 2;6 onwards. A notable difference between the acquisition of Pitjantjatjara clause chains and Turkish converbs is in the order of acquisition of semantic functions. In Turkish, children acquire temporal functions, such as sequential actions, before modifying functions, such as manner specification. In Pitjantjatjara, the order is reversed, with children first using clause chaining constructions for modification and simultaneous aspects of events before utilizing them to combine sequential actions. This raises questions regarding the distribution and relative timing of event combination and modification strategies. (shrink)

Recent research suggests that language evolution is a process of cultural change, in which linguistic structures are shaped through repeated cycles of learning and use by domain-general mechanisms. This paper draws out the implications of this viewpoint for understanding the problem of language acquisition, which is cast in a new, and much more tractable, form. In essence, the child faces a problem of induction, where the objective is to coordinate with others (C-induction), rather than to model the structure of the (...) natural world (N-induction). We argue that, of the two, C-induction is dramatically easier. More broadly, we argue that understanding the acquisition of any cultural form, whether linguistic or otherwise, during development, requires considering the corresponding question of how that cultural form arose through processes of cultural evolution. This perspective helps resolve the “logical” problem of language acquisition and has far-reaching implications for evolutionary psychology. (shrink)

Material acquisition—buying, inheriting, being given—and nonmaterial—learning a word, assimilating a form—have been likened, and in both, meaningful acquisition cannot take place without a taxonomy, a scheme of categories into which the acquired element can be fitted. Then with these elements—both material and nonmaterial—we create a world or build and project a self, the painter and the interior decorator equally manipulating the elements in a vocabulary. The coarseness of such an outlook seems to bludgeon away long-established fine distinctions. We need not (...) deny, however, that there may be a kind of "indifference" in regard to "the real existence of the thing" which allows us "to play the part of judge in matters of taste," as Kant would have it,1 we need not deny the existence of an "aesthetic attitude: it is just that such indifference and such an attitude probably don't have much to do with our day-to-day experience of artifacts and perhaps needn't. The "aesthetic attitude" was not long ago defined by Jerome Stolnitz as "disinterested and sympathetic attention to and contemplation of any object of awareness whatever, for its own sake alone."2 Stolnitz is at pains to distinguish the aesthetic attitude from "interests" with which it may be preferable to confuse it. "One of them," he writes, "is the interest in owning a work of art for the sake of pride or prestige". And again, "Another nonaesthetic interest is the 'cognitive,' i.e., the interest in gaining knowledge about an object". Both these interests sound rather acquisitive, and let us consider the "aesthetic attitude" as somehow tied in everyday practice to the bundle of "acquiring" activities. · 1.

We use the comparative method of language acquisition research to investigate children’s expression of directional expressions in two Eastern Mayan languages – K’iche’ and Mam. Both languages add clitics derived from verbs such as ‘go’ and ‘stay’ to their verb complex to express the direction an agent takes in the course of accomplishing an event. Historic changes to the prosodic structure of the verb complex in both languages explain why the directional clitics are predominately postverbal in K’iche’, while they occur (...) in preverbal and postverbal positions in Mam. Prosody explains why K’iche’ children initially produce clitics postverbally, while Mam children produce clitics both preverbally and postverbally. Prosody also explains why the children acquiring both languages produce morphemes in the verb complex that are relatively infrequent but prosodically prominent, while omitting obligatory morphemes that are prosodically weak.

In light of the dramatic growth of Chinese learners worldwide and a need for cross-linguistic research on Chinese literacy development, this study drew upon theories of visual complexity effect (Su & Samuels, 2010) and dual-coding processing (Sadoski & Paivio, 2013) and investigated a) the effects of character properties (i.e., visual complexity and radical presence) on character acquisition and b) the relationship between individual learner differences in radical awareness and character acquisition. Participants included adolescent English-speaking beginning learners of Chinese in the (...) U.S. Following Kuo et al. (2014), a novel character acquisition task was used to investigate the process of acquiring the meaning of new characters. Results showed that a) characters with radicals and with less visual complexity were easier to acquire than characters without radicals and with greater visual complexity; and b) individual differences in radical awareness were associated with the acquisition of all types of characters, but the association was more pronounced with the acquisition of characters with radicals. Theoretical and practical implications of the findings were discussed. (shrink)

Debating on Second Language Acquisition is not merely in terms of concept but also the real phenomena which postulate each research result. It needs more investigation on SLA due to the various realities on how children and adults acquire and learn any language. This research aims to describe how children and adults acquire and learn their first and second language. Participants consisted of children and adults whose ages determined by the researcher based on the purposive sampling technique. They were all (...) six persons and chosen based on certain characteristics. Content analysis technique was applied in order to analyze all data gained. The result showed that since human alive inside mother’s womb especially at up to the age of three months, a fetus has tried to acquire sounds subconsciously. Language proficiency is really determined by three factors of Phased Process Approach namely Subconscious Acquisition, Conscious Acquisition, and Learning. The ideal time for learning something is begun from the age of 2 or 3 years old, by the fact that children have had the ability to bear a meaning on any input that they catch. The learning process has been begun within the process of acquisition. Based on the findings, it is clear that the children acquire the language step by step based on the development of the brain. Children acquire language is just the same as adult in acquiring the language although there will be some constraints faced by adult concern with the first language because adult has had the strong basis of the first language just than children.

ABSTRACTA paper in two parts, the first is a critique of the commonly held view among both cognitivist and non-cognitivist sport philosophers that conscious mental representation of knowledge that is a necessary condition for skill acquisition. The second is a defense of a necessary causal condition for skill acquisition, a necessary causal condition that is mimetic, physically embodied, and socially embedded. To make my case I rely throughout on a common thought experiment in and beyond the philosophy of sport literature, (...) the seminal work of Kuhn and Quine counter the representational theory of knowledge, and recent argument in the philosophy of sport related to neurophysiology, cognition, and intentionality. Ultimately I conclude that the failure of a necessary representational condition and its replacement by a necessary casual condition in skill acquisition jeopardizes much of what has been said in the philosophy of sport about not just skill acquisition but the more popular topic of high-level skill. It does, because it challenges the assumption that there is some necessary baseline knowledge that which, according to cognitivists, is brought forward in some way into highly skillful performance or, according to non-cognitivists, is somehow left behind or subsumed into a background in highly skillful performance.

For more than 60 years, Chomsky has been an intellectual Colossus bestriding the worlds of language, philosophy, and the cognitive sciences, and focusing attention on the whole field and emphasizing the crucial importance of domains overlooked by the mainstream. One such area is the study of first‐language acquisition. This chapter considers “atypical acquisition” to cover two conceptually related situations. First, it covers a variety of cases where there is an obvious “poverty of the stimulus” in that children either receive or (...) perceive no linguistic input at the essential early stages referred to as critical periods. Second, it covers where there is rather the opposite situation. The chapter presents atypicality in language acquisition that stems from the learner's atypical neurological profile rather than environmental or input properties. It focuses on Developmental Language Disorder, Autism Spectrum Disorder, and the case of the polyglot‐savant Christopher to exemplify atypical acquisition. (shrink)

The acquisition of professional knowledge is a core issue in the formation of auditor industry expertise; however, previous literature has neglected the time required for auditors to acquire professional knowledge. We examine the audit quality and fees of audit firms in different stages of an auditor acquiring professional knowledge and find that, in the initial stage of the process of knowledge acquisition, audit quality and audit fees decrease. However, in the long run, knowledge learning has a more obvious effect on (...) the improvement of audit quality and audit fees. Specifically, knowledge learning has a positive effect on the development of audit firms. (shrink)

Two experiments are reported that evaluated survey learning of youth with DS and typically developing children (TD) matched on Mental Age (MA). In Experiment 1, the experimenter navigated participants through a novel virtual environment along a circuitous path, beginning and ending at a target landmark (i.e., a door). Then, the participants were placed at a pre-specified location in the environment and instructed to navigate to the same door using the shortest possible path from their current location. They completed the task (...) three times: once after being shown the environment one time, once after three exposures, and once after five exposures. Results indicated that the participants with DS exhibited significantly less skill at identifying the shortcut than did the TD participants. In Experiment 2, participants learned two overlapping routes through a simple environment. Following acquisition, they were tested on several measures of survey knowledge: finding a shortcut, identifying the direction of landmarks not currently visible from their location in the environment, and recognizing a bird’s-eye representation of the overall environment. The results of Experiment2 indicated that the participants with DS were at least as good as the TD participants on all of our measures of survey learning. Hence, we concluded that people with DS can acquire some survey knowledge when they learn a simple environment. However, the performance of both groups was relatively poor in Experiment 2, indicating a need to consider identifying the mechanisms underlying the poor performance on wayfinding of people with DS. Identifying the underlying mechanisms, is a logical first step in devising methods of enhancing environmental learning of people with DS. (shrink)

We are reviewing and summarizing evidence for the processes of acquisition of information outside of conscious awareness (processing information about covariations, nonconscious indirect and interactive inferences, self-perpetuation of procedural knowledge). A considerable amount of data indicates that as compared to consciously controlled cognition, the nonconscious information-acquisition processes are not only much faster but also structurally more sophisticated in the sense that they are capable of efficient processing of multidimensional and interactive relations between variables. Those mechanisms of nonconscious acquisition of information (...) provide a major channel for the development of procedural knowledge which is indispensable for such important aspects of cognitive functioning as encoding and interpretation of stimuli and the triggering emotional reactions.

Suppose libertarians could prove that durable, unqualified private property rights could be created through 'original acquisition' of unowned resources in a state of nature. Such a proof would cast serious doubt on the legitimacy of the modern state. It could also render the approach to property rights that I favour irrelevant. I argue here that none of the familiar Lockean-libertarian arguments for a strong natural right to acquisition succeed, and that any successful argument for grounding a right to acquire would (...) have to use my favoured approach to property rights - the 'vector-sum' approach. I conclude with some doubts about original acquisition theory and natural property rights. (shrink)

Christiansen & Chater (C&C) focus solely on general-purpose cognitive processes in their elegant conceptualization of language evolution. However, numerous developmental facts attested in L1 acquisition confound C&C's subsequent claim that the logical problem of language acquisition now plausibly recapitulates that of language evolution. I argue that language acquisition should be viewed instead as a multi-layered construction involving the interplay of general and domain-specific learning mechanisms.

A recent hypothesis in empirical brain research on language is that the fundamental difference between animal and human communication systems is captured by the distinction between finite-state and more complex phrase-structure grammars, such as context-free and context-sensitive grammars. However, the relevance of this distinction for the study of language as a neurobiological system has been questioned and it has been suggested that a more relevant and partly analogous distinction is that between non-adjacent and adjacent dependencies. Online memory resources are central (...) to the processing of non-adjacent dependencies as information has to be maintained across intervening material. One proposal is that an external memory device in the form of a limited push-down stack is used to process non-adjacent dependencies. We tested this hypothesis in an artificial grammar learning paradigm where subjects acquired non-adjacent dependencies implicitly. Generally, we found no qualitative differences between the acquisition of non-adjacent dependencies and adjacent dependencies. This suggests that although the acquisition of non-adjacent dependencies requires more exposure to the acquisition material, it utilizes the same mechanisms used for acquiring adjacent dependencies. We challenge the push-down stack model further by testing its processing predictions for nested and crossed multiple non-adjacent dependencies. The push-down stack model is partly supported by the results, and we suggest that stack-like properties are some among many natural properties characterizing the underlying neurophysiological mechanisms that implement the online memory resources used in language and structured sequence processing.

The five-stage skill-acquisition model developed by Stuart Dreyfus is revisited as an integral part of culture acquisition. This examination sheds light on the role intuitive knowledge plays during the 4th and 5th stages. When modern technology becomes universal and detaches itself from culture, this intuitive knowledge changes. This accounts for the loss of technologies that were socially appropriate and environmentally sustainable.

An experiment explored the acquisition of conscious and unconscious knowledge of semantic prosody in a second language under incidental and intentional learning conditions. Semantic prosody is the conotational coloring of the semantics of a word, largely uncaptured by dictionary definitions. Contrary to some claims in the literature, we revealed that both conscious and unconscious knowledge were involved in the acquisition of semantic prosody. Intentional learning resulted in similar unconscious but more conscious knowledge than incidental learning. The results are discussed in (...) terms of second language learning and the nature of unconscious knowledge. (shrink)

Specification acquisition in the system design process has been improved since the middle of the 1980s when the upper CASE tools appeared. On the contrary the quality of requirement acquisition in the upper processes of system design has not been enhanced as much as specification acquisition. Understanding the user's requirements is indispensable as one of the basic conditions for building systems that can really satisfy users.This article discusses obtaining requirement knowledge, in terms of human-centred design. The focus is on the (...) process of requirement acquisition, where there is room for one to make full use of human knowledge in a dynamic manner. (shrink)

The study considers development and use of verb/predicate chaining constructions by Hebrew speakers from early childhood to adolescence, based on analysis of authentic conversational and narrative corpora. Three types of such constructions are considered, ordered hierarchically by stage of acquisition: (1) monoclausal extended predicates consisting of a verb (modal, aspectual, or evaluative) marked for tense or mood and followed by one or more complements in the infinitive – e.g., yaxol la-asot ‘can, is able to-do’; (2) coreferential interclausal predicate chaining; and (...) (3) mature discursively-motivated topic-chaining. Relevant typological features of Modern Hebrew are reviewed to explain the lack of canonic clause-chaining construction in the language (e.g. the paucity of non-finite constructions in everyday usage, lack of an uninflected basic form of verbs, lack of auxiliary verbs expressing categories of aspect and voice, and monolexemic verb-internal complexity). Monoclausal verb-chaining emerges early in the speech of toddlers in interaction with their caretakers, whereas predicate chaining by coordination across clauses occurs only later, and chunking of such constructions at the service of discourse connectivity is a late-developing device. Nonfinite subordination is an advanced form of clause-combining, in contrast to straightforward subordination with the multifunctional subordinator še’that’. The conclusion is that, unlike the obligatorily fused monoclausal “extended predicates”, bi- and multi-clausal predicate chaining represents an optional rhetorical choice on the part of a given speaker-writer in a particular communicative context.

What makes a word easy to learn? Early‐learned words are frequent and tend to name concrete referents. But words typically do not occur in isolation. Some words are predictable from their contexts; others are less so. Here, we investigate whether predictability relates to when children start producing different words (age of acquisition; AoA). We operationalized predictability in terms of a word's surprisal in child‐directed speech, computed using n‐gram and long‐short‐term‐memory (LSTM) language models. Predictability derived from LSTMs was generally a better (...) predictor than predictability derived from n‐gram models. Across five languages, average surprisal was positively correlated with the AoA of predicates and function words but not nouns. Controlling for concreteness and word frequency, more predictable predicates and function words were learned earlier. Differences in predictability between languages were associated with cross‐linguistic differences in AoA: the same word (when it was a predicate) was produced earlier in languages where the word was more predictable.

The search for knowledge has continued to expand to new domains since its start in the seventeenth century. Some of them have proved unusually resistant. Methods have had to proliferate to deal with the obstacles, for example in the social domain. There also have been ideological reactions. Surprisingly frequently, methods and activities that appear to be effective in dealing with such domains are classified as "preliminary" or are distinguished by a "point of view" that has yet to be transcended to (...) achieve "true" knowledge. One such activity is the acquisition of high quality experience. It is argued in the paper that it does not deserve being treated as a poor relative. It has a history of its own and can point to many successes, for example in the development of new values and emotions. Its only drawback seems to be that the search for high quality experiences has tended to be heuristic, or if one wishes, artistic. This situation is changing, however. In the paper the differences between the acquisition of knowledge and that of high quality experience are delineated. It is argued that facilitation of the latter's searches requires the development of interactions between entities that generate and structure experiences--i.e., of human collectives that stabilise sufficiently to execute a collective action in their environment. They are characterised by the use of coordinating languages. (shrink)

Using connectionist modeling, we address fundamental questions concerning the acquisition process of musical tonal schema of listeners. Compared to models of previous studies, our connectionist model (Learning Network for Tonal Schema, LeNTS) was better equipped to fulfill three basic requirements. Specifically, LeNTS was equipped with a learning mechanism, bound by culture-general properties, and trained by sufficient melody materials. When exposed to Western music, LeNTS acquired musical ‘scale’ sensitivity early and ‘harmony’ sensitivity later. The order of acquisition of scale and harmony (...) sensitivities shown by LeNTS was consistent with the culture-specific acquisition order shown by musically westernized children. The implications of these results for the acquisition process of a tonal schema of listeners are as follows: (a) the acquisition process may entail small and incremental changes, rather than large and stage-like changes, in corresponding neural circuits; (b) the speed of schema acquisition may mainly depend on musical experiences rather than maturation; and (c) the learning principles of schema acquisition may be culturally invariant while the acquired tonal schemas are varied with exposed culture-specific music.

Capitalism is often defended by appeals to natural rights: only in a free market, it is said, are people protected from the illegitimate intrusions of others. Coercion, either to prevent exchanges or to redistribute wealth, violates people's rights. But much of the property people have acquired came not from their own effort or the efforts of those who gave them gifts, but instead was taken from nature. Thus the question I propose to discuss in this paper: How is it that (...) an unowned natural resource can legitimately be acquired for private benefit? Much thought has been given by libertarian defenders of capitalism to justifying the claim that, once owned, property cannot be taken without its owner's consent. Relatively little attention has been paid, however, to how the original acquisition can be justified. Indeed, I argue here that if one approaches the problem of resource appropriation from the perspective of the Lockean ‘proviso,’ that enough and as good must be left in common, then the typical method of acquiring property under capitalism is unjust. Libertarians must either give up the individualistic, state of nature approach to economic justice or admit that appropriation of natural resources requires compensation of people who do not get a share of the resource.

Disciplinary boundaries become increasingly unclear when grappling with “wicked problems,” which present a complex set of policy, cultural, technological, and scientific dimensions. “T-shaped” professionals, i.e. individuals with a depth and breadth of expertise, are being called upon to play a critical role in complex problem-solving. This paper unpacks the notion of the “T-shaped expert” and seeks to situate it within the broader academic literature on expertise, integration, and developmental learning. A component of this project includes an exploratory study, which is (...) aimed at evaluating the emergent attributes of T-shaped expertise in two different educational programs completed between January and May in 2015. The two programs build disciplinary knowledge in science, technology engineering, and mathematics fields at the core, while expanding the students’ awareness and comprehension of other expertise. The courses introduced science and engineering students to case study topics focusing around complex human-technological-ecological systems in a nanotechnology and society course; and the governance of genetically modified organisms in a science, technology, and society course. We analyze pre- and post-test data from this pilot project before presenting findings that pertain to student learning, as well as variants in the methodology and reflect on the utility of the selected methodology for evaluating expertise as it evolves over time. The paper closes with a discussion of a theory of acquisition with implications for delineating early attributes and characteristics of T-shaped expertise. (shrink)
