We have previously shown that several brain areas are activated both during sequence learning at wake and during subsequent rapid-eye-movements (REM) sleep (Nat. Neurosci. 3 (2000) 831– 836), suggesting that REM sleep participates in the reprocessing of recent memory traces in humans. However, the nature of the reprocessed information remains open. Here, we show that regional cerebral reactivation during posttraining REM sleep is not merely related to the acquisition of basic visuomotor skills during prior practice of the serial (...) reaction time task, but rather to the implicit acquisition of the probabilistic rules that defined stimulus sequences. Moreover, functional connections between the reactivated cuneus and the striatum—the latter being critical for implicit sequence learning—are reinforced during REM sleep after practice on a probabilistic rather than on a random sequence of stimuli. Our results therefore support the hypothesis that REM sleep is deeply involved in the reprocessing and optimization of the high-order information contained in the material to be learned. In addition, we show that the level of acquisition of probabilistic rules attained prior to sleep is correlated to the increase in regional cerebral blood flow during subsequent REM sleep. This suggests that posttraining cerebral reactivation is modulated by the strength of the memory traces developed during the learning episode. Our data provide the first experimental evidence for a link between behavioral performance and cerebral reactivation during REM sleep. © 2003 Elsevier Inc. All rights reserved. (shrink)

This article suggests evidence for and reasons why prior acquisition may either facilitate or inhibit acquisition of a new construction. It investigates acquisition of the German passive and future constructions which contain a lexical verb with either the auxiliary sein “to be” or werden “to become”, and are related through these to potential supporting constructions. We predicted that a supported construction should be acquired earlier, faster, and unusually rapidly. An inhibited construction should show an extended depressed usage. (...) We analyzed a dense corpus of a German boy between 2;0 and 5;0. He acquired the sein- before the werden-passive. The former was supported by his prior acquisition of the sein copula, whereas the werden-passive itself supported one werden copula construction. He acquired the werden-future extremely slowly due to the hindrance of a semantically identical construction. These results fit with an emergentist approach in which apparently “sudden” acquisition is still due to gradual learning mechanisms. (shrink)

Do children acquire language rapidly, or slowly? From the vantage point of linguistic theory, all normal children could be expected to have full command of a rich and intricate system of linguistic principles in just a few years. Experimental studies of child language, however, paint a different picture of language development: It appears that language learning extends over many years, with children making numerous missteps along the way. Attempts have been made to reconcile theory and data, by looking for features (...) of language development that might impede the emergence of linguistic knowledge, and by looking in more detail at the experimental findings themselves. We begin by reviewing the reasons, based on current linguistic theory, for anticipating the rapid growth of linguistic knowledge in children. Then we turn to the laboratory, to consider both findings that do not sit well with the expectations of linguistic theory, as well as ones that comport well with theory. (shrink)

This article is concerned with the childhood experience that seems to be preparatory for the onset of bulimia. Three women's serial experiences of bulimia were investigated and one pattern of experiencing that led to bulimia emerged. As the interview process deepened, the data moved from symptom-related to life-related. The general structure that captured the essence of the lived experience of bulimia remained the same but the individual experiences varied as these women live out their unique lives. In understanding the totality (...) of the phenomenon of bulimia, it is important to remember that although each of the six key constituents is described separately, in the life-world all the constituents merge together as they interact with each other and with the whole of the experience. These bulimic women reported having family backgrounds in which they experienced a sense of diminished self and dissatisfaction in interactions with significant others and self. They found themselves pressured to maintain a less than integrated life, and in rapid transition from 'awareful' behaving to automatic and anonymous functioning. A psychological hunger seems to possess them and this is lived out during the anonymous phase of their existence. Their need for the mastery and control ordinarily lacking in their lives becomes a symptomatic expression that has relevance for them in respect to the deep psychological pain that is only partially expressed. The phenomenal body and self are given priority over objective reality, resulting in distorted perceptions of "fatness" and feelings of terror of "fat.". (shrink)

The present commentary emphasizes that the acquisition of fear always involves complex changes in several quasi-independent response systems. Stimulus-specific electrodermal response differentiation as well as the bias to overestimate the belongingness of certain stimulus pairs mainly indicates cognitive processes of selective orienting and attention. Emotion, however, also involves the activation of subcortical motivational circuits. Why certain stimuli acquire rapid access to these basic motivational systems is not explained by the expectancy bias model.

Previous studies have found the effect of cognitive skills on reading ability, but the role of different reading-related skills in acquisition of Chinese as a second/foreign language remains unexplored. Prior meta-analyses on the relationship between cognitive skills and reading have been conducted primarily in native English-speaking or Mandarin-speaking children. The purpose of the present meta-analysis was to examine the relationship between Chinese reading-related skills and Chinese word reading of CSL/CFL learners. A search of English and Chinese databases yielded 42 (...) effect sizes, comprising 1103 subjects met the criteria for meta-analysis and were included in the final meta-analysis. Results revealed a moderate relationship between phonological awareness, morphological awareness, orthographic awareness, rapid automatized naming and Chinese word reading in CSL/CFL learners. In addition, a moderating effect of length of study on the relationship between phonological awareness and Chinese word reading : phonological awareness and Chinese word reading correlated more strongly for beginning learners than for advanced learners. These results suggest importance of cognitive factors in the acquisition of Chinese word reading as a second language. Results also shed light on the impact of length of study on the influence from phonological awareness to the sensitive period of phonological learning for CSL/CFL learners. (shrink)

Previous studies of verbal short-term memory indicate that STM for serial order may be linked to language development and developmental language disorder. To clarify whether a domain-general mechanism is impaired in DLD, we studied the relations between age, non-verbal serial STM, and language competence. We hypothesized that non-verbal serial STM differences between groups of children with DLD and typically developing children are linked to their language acquisition differences. Fifty-one children with DLD and sixty-six TD children participated as part of (...) the HelSLI project in this cross-sectional study. The children were 4–6-year-old monolingual native Finnish speakers. They completed several tests of language and cognitive functioning, as well as new game-like tests of visual and auditory non-verbal serial STM. We used regression analyses to examine how serial STM moderates the effect of age on language. A non-verbal composite measure of serial visual and auditory STM moderated cross-sectional development of receptive language in the children with DLD. This moderation was not observed in the TD children. However, we found more rapid cross-sectional development of non-verbal serial STM in the TD children than in the children with DLD. The results suggest that children with DLD may be more likely to have compromised general serial STM processing and that superior non-verbal serial STM may be associated with better language acquisition in children with DLD.

During the last two decades, economic development has been slow in most of the countries of Sub-Saharan Africa (World Bank, 1981). In the middle of the 1970s when the world economy experienced inflation and recession, no where did the crises hit with greater impact than in Sub-Saharan Africa. This region shows slow overall economic growth, sluggish agricultural performance, rapid rates of population increase, and a balance of payment crises. Between 1960 and 1979, per capita income in 19 countries grew (...) by less than 1% per annum. During the last decade 15 countries recorded a negative rate of income growth per capita (World Bank, 1981).The economic state of the oil exporting countries (Angola, Congo and Nigeria) in Sub-Saharan Africa is not any different. The average annual growth rate of GNP per capita from 1960–1979 shows Angola at –2.1%, Congo at 0.9% and Nigeria at 3.7%. (shrink)

Nietzsche's wider political thinking has been widely recognized as therapeutic in orientation, as part of its connection to the history of psychology. This chapter examines the remarks that Nietzsche does make with respect to the political in Dawn, focusing on his concern with the effects on humanity of capital and industrial development upon Europeans. It explores his remarks on migration as a therapeutic measure for the workers of Europe and considers some of the problematic claims involved in Nietzsche's appeal to (...) migration as a key part of his therapeutic approach. The chapter discusses whether or not Nietzsche's therapeutic politics in Dawn can be defended. Nietzsche contends that money substitutes for truth, and that the same fanaticism that previously drove truth‐seeking now drives people to the increasing, and increasingly rapid, acquisition of wealth.

It is predicted that the rapid acquisition of new genetic knowledge and related applications during the next decade will have significant implications for virtually all members of society. Currently, most people get exposed to information about genes and genetics only through stories publicized in the media. We sought to understand how individuals in the general population used and understood the concepts of ???genetics??? and ???genes.??? During in-depth one-on-one telephone interviews with adults in the United States, we asked questions (...) exploring their basic understanding of these terms, as well as their belief as to the location of genes in the human body. A wide range of responses was received. Despite conversational familiarity with genetic terminology, many noted frustration or were hesitant when trying to answer these questions. In addition, some responses reflected a lack of understanding about basic genetic science that may have significant implications for broader public education measures in genetic literacy, genetic counseling, public health practices, and even routine health care.

Gerald Harrison has argued that the readiness with which we have and agree to moral intuitions about the value of disembodied persons shows that persons are essentially non-material, for if we were essentially material we would not so easily be able to ascribe moral value to an impossible non-material person. To support this point, he advances a somewhat novel metaphor of intuitions as a "call" to a help desk which can answer our queries about counter-factual scenarios. I first point out (...) that the help desk metaphor is not only compatible with, but actually suggestive of, the possibility of systematic error on the part of our intuitions. But more crucially, rapid acquisition of and widespread agreement on even plausible intuitions about counter-factual scenarios does nothing to show that the counter-factual scenarios are possible, let alone true, giving several other counter-examples to this idea. I conclude with the suggestion that imagining such counter-factual scenarios should not be seen as a mode of accessing a fixed source of truths in a "help desk" manual, but as a constructive way of understanding the relationship between concepts, and hence ultimately as a mode of writing small parts of this heretofore unwritten text.

Memory is fleeting. New material rapidly obliterates previous material. How, then, can the brain deal successfully with the continual deluge of linguistic input? We argue that, to deal with this “Now-or-Never” bottleneck, the brain must compress and recode linguistic input as rapidly as possible. This observation has strong implications for the nature of language processing: (1) the language system must “eagerly” recode and compress linguistic input; (2) as the bottleneck recurs at each new representational level, the language system must build (...) a multilevel linguistic representation; and (3) the language system must deploy all available information predictively to ensure that local linguistic ambiguities are dealt with “Right-First-Time”; once the original input is lost, there is no way for the language system to recover. This is “Chunk-and-Pass” processing. Similarly, language learning must also occur in the here and now, which implies that language acquisition is learning to process, rather than inducing, a grammar. Moreover, this perspective provides a cognitive foundation for grammaticalization and other aspects of language change. Chunk-and-Pass processing also helps explain a variety of core properties of language, including its multilevel representational structure and duality of patterning. This approach promises to create a direct relationship between psycholinguistics and linguistic theory. More generally, we outline a framework within which to integrate often disconnected inquiries into language processing, language acquisition, and language change and evolution. (shrink)

How does a child rapidly acquire and develop a structured mental organization for the vast number of words in the first years of life? How does a bilingual individual deal with the even more complicated task of learning and organizing two lexicons? It is only until recently have we started to examine the lexicon as a dynamical system with regard to its acquisition, representation, and organization. In this article, I outline a proposal based on our research that takes the (...) dynamical approach to the lexicon, and I discuss how this proposal can be applied to account for lexical organization, structural representation, and competition within and between languages. In particular, I provide computational evidence based on the DevLex model, a self‐organizing neural network model, and neuroimaging evidence based on functional magnetic resonance imaging (fMRI) studies, to illustrate how children and adults learn and represent the lexicon in their first and second languages. In the computational research, our goal has been to identify, through linguistically and developmentally realistic models, detailed cognitive mechanisms underlying the dynamic self‐organizing processes in monolingual and bilingual lexical development; in the neuroimaging research, our goal has been to identify the neural substrates that subserve lexical organization and competition in the monolingual and the bilingual brain. In both cases, our findings lead to a better understanding of the interactive dynamics involved in the acquisition and representation of one or multiple languages. (shrink)

Words associated with perceptually salient, highly imageable concepts are learned earlier in life, more accurately recalled, and more rapidly named than abstract words (R. W. Brown, 1976; Walker & Hulme, 1999). Theories accounting for this concreteness effect have focused exclusively on semantic properties of word referents. A novel possibility is that word structure may also contribute to the effect. We report a corpus-based analysis of the phonological and morphological structures of a large set of nouns with imageability ratings (N = (...) 2,023). High- and low-imageability nouns differed by length, etymology, prosody, affixation, phonological neighborhood density, and rates of consonant clustering. On average, nouns denoting abstract concepts were longer, more derivationally complex, and emerged in English from a different distribution of languages than did concrete nouns. We address implications for interactivity of word form and meaning as pertain to theories of word concreteness, lexical acquisition, and word processing. (shrink)

Natural languages contain many layers of sequential structure, from the distribution of phonemes within words to the distribution of phrases within utterances. However, most research modeling language acquisition using artificial languages has focused on only one type of distributional structure at a time. In two experiments, we investigated adult learning of an artificial language that contains dependencies between both adjacent and non-adjacent words. We found that learners rapidly acquired both types of regularities and that the strength of the adjacent (...) statistics influenced learning of both adjacent and non-adjacent dependencies. Additionally, though accuracy was similar for both types of structure, participants’ knowledge of the deterministic non-adjacent dependencies was more explicit than their knowledge of the probabilistic adjacent dependencies. The results are discussed in the context of current theories of statistical learning and language acquisition. (shrink)

With the rapid growth of information technology and sports, analyzing sports information has become an increasingly challenging issue. Sports big data come from the Internet and show a rapid growth trend. Sports big data contain rich information such as athletes, coaches, athletics, and swimming. Nowadays, various sports data can be easily accessed, and amazing data analysis technologies have been developed, which enable us to further explore the value behind these data. In this paper, we first introduce the background (...) of sports big data. Secondly, we review sports big data management such as sports big data acquisition, sports big data labeling, and improvement of existing data. Thirdly, we show sports data analysis methods, including statistical analysis, sports social network analysis, and sports big data analysis service platform. Furthermore, we describe the sports big data applications such as evaluation and prediction. Finally, we investigate representative research issues in sports big data areas, including predicting the athletes’ performance in the knowledge graph, finding a rising star of sports, unified sports big data platform, open sports big data, and privacy protections. This paper should help the researchers obtaining a broader understanding of sports big data and provide some potential research directions. (shrink)

With its focus on intellectual virtues and their role in the acquisition and transmission of knowledge and related epistemic goods, virtue epistemology provides a rich set of tools for educational theory and practice. In particular, characteristics under the rubric of "responsibilist" virtue epistemology, like curiosity, open-mindedness, attentiveness, intellectual courage, and intellectual tenacity, can help educators and students define and attain certain worthy but nebulous educational goals like a love of learning, lifelong learning, and critical thinking. This volume is devoted (...) to exploring the intersection between virtue epistemology and education. It assembles leading virtue epistemologists and philosophers of education to address such questions as: Which virtues are most essential to education? How exactly should these virtues be understood? How is the goal of intellectual character growth related to other educational goals, for example, to critical thinking and knowledge-acquisition? What are the "best practices" for achieving this goal? Can growth in intellectual virtues be measured? The chapters are a prime example of "applied epistemology" and promise to be a seminal contribution to an area of research that is rapidly gaining attention within epistemology and beyond. (shrink)

Perceptual learning is an enduring change in the perceptual system – and our resulting perceptions – due to practice or repeated exposure to a perceptual stimulus. It is involved in the acquisition of perceptual expertise: the ability to make rapid and reliable high-level categorizations of objects unavailable to novices. Attentional weighting is one process by which perceptual learning occurs. Advancing our understanding of this process is of particular importance for understanding what is learned in perceptual learning. Attentional weighting (...) seems to favour the hypothesis that what experts learn is simply to better direct their attention to elements of the stimulus relevant to making post-perceptual categorizations. Here I argue against this hypothesis. Attentional weighting is an integral component of the process that allows experts to come to represent high-level properties in perceptual experience. (shrink)

Linguistic predictions may be generated from and evaluated against a representation of events and referents described in the discourse. Compatible with this idea, recent work shows that predictions about novel noun phrases include their definiteness. In the current follow-up study, we ask whether people engage similar prediction-related processes for definite and indefinite referents. This question is relevant for linguistic theories that imply a processing difference between definite and indefinite noun phrases, typically because definiteness is thought to require a uniquely identifiable (...) referent in the discourse. We addressed this question in an event-related potential (ERP) study (N = 48) with preregistration of data acquisition, preprocessing, and Bayesian analysis. Participants read Dutch mini-stories with a definite or indefinite novel noun phrase (e.g., “het/een huis,” the/a house), wherein (in)definiteness of the article was either expected or unexpected and the noun was always strongly expected. Unexpected articles elicited enhanced N400s, but unexpectedly indefinite articles also elicited a positive ERP effect at frontal channels compared to expectedly indefinite articles. We tentatively link this effect to an antiuniqueness violation, which may force people to introduce a new referent over and above the already anticipated one. Interestingly, expectedly definite nouns elicited larger N400s than unexpectedly definite nouns (replicating a previous surprising finding) and indefinite nouns. Although the exact nature of these noun effects remains unknown, expectedly definite nouns may have triggered the strongest semantic activation because they alone refer to specific and concrete referents. In sum, results from both the articles and nouns clearly demonstrate that definiteness marking has a rapid effect on processing, counter to recent claims regarding definiteness processing. (shrink)

Attention is often dichotomized into controlled vs. automatic processing, where controlled processing is slow, flexible, and intentional, and automatic processing is fast, inflexible, and unintentional. In contrast to this strict dichotomy, there is mounting evidence for context-specific processes that are engaged rapidly yet are also flexible. In the present study we extend this idea to the domain of implicit learning to examine whether flexibility in automatic processes can be implemented through the reliance on contextual features. Across three experiments we show (...) that participants can learn implicitly two complementary sequences that are associated with distinct contexts, and that transfer of learning when the two contexts are randomly intermixed depends on the distinctiveness of the two contexts. Our results point to the role of context-specific processes in the acquisition and expression of implicit sequence knowledge, and also suggest that episodic details can be represented in sequence knowledge.

It is widely assumed that human learning and the structure of human languages are intimately related. This relationship is frequently suggested to derive from a language-specific biological endowment, which encodes universal, but communicatively arbitrary, principles of language structure (a Universal Grammar or UG). How might such a UG have evolved? We argue that UG could not have arisen either by biological adaptation or non-adaptationist genetic processes, resulting in a logical problem of language evolution. Specifically, as the processes of language change (...) are much more rapid than processes of genetic change, language constitutes a both over time and across different human populations, and, hence, cannot provide a stable environment to which language genes could have adapted. We conclude that a biologically determined UG is not evolutionarily viable. Instead, the original motivation for UG arises because language has been shaped to fit the human brain, rather than vice versa. Following Darwin, we view language itself as a complex and interdependent which evolves under selectional pressures from human learning and processing mechanisms. That is, languages themselves are shaped by severe selectional pressure from each generation of language users and learners. This suggests that apparently arbitrary aspects of linguistic structure may result from general learning and processing biases deriving from the structure of thought processes, perceptuo-motor factors, cognitive limitations, and pragmatics.

The co-evolutionary concept of tri-modal stable evolutionary strategy (SESH) of Homo sapiens is developed. The concept based on the principle of evolutionary complementarity of anthropogenesis: value of evolutionary risk and evolutionary path of human evolution are defined by descriptive (evolutionary efficiency) and creative-teleological (evolutionary correctness) parameters simultaneously, that cannot be instrumental reduced to others ones. Resulting volume of both parameters define the vectors of human evolution by two gear mechanism ˗ genetic and cultural co-evolution and techno-humanitarian balance. Explanatory model and (...) methodology of evaluation of creatively teleological evolutionary risk component of NBIC technological complex is proposed. The mechanism of influence of each module on the evolution of the two remaining modules of SESH a priori can be twofold: (1) informational co-evolution (direct selective pressure); (2) semantic co-evolution (time-varying semantic code, the compliance of the biological, socio- cultural and techno-rationalist adaptive modules of human stable evolutionary strategy). More rapidly evolving autonomous element of the co-evolutionary pair becomes making sense factor for the partner. Semantic co-evolution is the discrete acquisition of adaptive significance of individual alleles by changing socio-cultural types, manifested as an increase in the genetic variability of populations of Homo sapiens, and domesticated species parallel to socio-culturogenesis. The socio- cultural landscape leads to drastically difference of direction in biological evolution of Atlantic and East-Slavic ethnicities/civilizations. (shrink)

This would have been a better book if Sampson had argued his main point, the usefulness of the Simonian principle as an explanation of the evolution, structure, and acquisition of language, on its own merits, instead of making it subsidiary to his attack on ‘limited-minders’ (e.g., Noam Chomsky). The energy he has spent on the attack he might then have been willing and able to employ in developing his argument at reasonable length and detail. He might then have found (...) that argument faulty, or even wrong. Underdeveloped as it is, however, his point about the Simonian principle does seem to have thepossibility of some significance in understanding the empirical issues of this book (and the dichotomy of ‘limited’ and ‘creative’ minds is certainly not one of these).What Sampson has done inMaking Sense has the appearance of science, and theoretical linguistics, and therefore it is somewhat puzzling to find the conclusions that the human mind cannot be scientifically studied (p. 10), and that theoretical linguistics is a “mirage” (p. 210). His statement that It may still seem worthwhile to some to work out the exact implications for present-day linguistic structure of the fact that languages are evolved systems, but I cannot see that there is much glamour or, indeed, much substance in this task (p. 210) would surely be surprising to a geneticist or ethologist. We hope his apparent misunderstanding on this point will not lead him to give up his profession, in which he seems willing and able to make a significant contribution.What in particular is required is a clear indication of how the Simonian principle imposes itself in the ontogenesis of language. Consider Chomsky's example of the rule for forming questions in English. For sentence (1) below, children able to deal with such examples would give (2) but not (3) as the corresponding question (Chomsky, 1975, p. 31).The man who is tall is in the room.Is the man who is tall in the room?*Is the man who tall is in the room?Now compare Sampson's evolutionary explanation for the structure-dependence of rules which is illustrated in (1)-(3): “once a behavior-pattern has become thoroughly established, it will tend to be treated as a fixed given when used as a constituent of a more complex, later-learned behavior-pattern” (p. 183). In order for this to account for Chomsky's example it would have to be the case that children learn relative clauses before they learn questions, which simply isn't true.In conclusion, we wish not to seem unaware of the problems with the position Sampson is attacking, or unaware of the sometimes dogmatic way it too has been presented. Chomsky's hypothesis of innate linguistic ideas seems, fundamentally, to derive from the claimed rapidity and uniformity of language acquisition in the face of limited and degenerate data. Chomsky appears to have been unwilling to argue these points directly or to show their relation to others, for which he has argued, for example, the implausibility of some abstract constraint's having been learned (cf. 1971, pp. 22–44; 1975, pp. 30–33; 1980, pp. 35–52). And almost from his first invoking of rationalism in support of his linguistic method, Chomsky has himself resorted to an unnecessarily polemical attack on empiricism (cf. 1965, p. 58, n. 33). The innateness issue is just not clear or simple enough to justify so much animus, or even conviction. (shrink)

In spoken interactions, interlocutors carefully plan and time their utterances, minimising gaps and overlaps between consecutive turns. Cross-linguistic comparison has indicated that spoken languages vary only minimally in terms of turn-timing, and language acquisition research has shown pre-linguistic vocal turn-taking in the first half year of life. These observations suggest that the turn-taking system may provide a fundamental basis for our linguistic capacities. The question remains however to what extent our capacity for rapid turn-taking is determined by modality (...) constraints. The avoidance of overlapping turns could be motivated by the difficulty of hearing and speaking at the same time. If so, turn-taking in sign might show greater toleration for overlap. Alternatively, signed conversations may show a similar distribution of turn-timing as spoken languages, thus avoiding both gaps and overlaps. To address this question we look at turn-timing in question-answer sequences in spontaneous conversations of Sign Language of the Netherlands. The findings indicate that although there is considerable overlap in two or more signers' articulators in conversation, when proper allowance is made for onset preparation, post-utterance retraction and the intentional holding of signs for response, turn-taking latencies in sign look remarkably like those reported for spoken language. This is consistent with the possibility that, at least with regard to responses to questions, speakers and signers follow similar time courses in planning and producing their utterances in on-going conversation. This suggests that turn-taking systems may well be a shared cognitive infrastructure underlying all modern human languages, both spoken and signed. (shrink)

Intelligible speakers achieve specific vocal tract constrictions in rapid sequence. These constrictions are associated in theory with speech motor goals. Adult-focused models of speech production assume that discrete phonological representations, sequenced into word-length plans for output, define these goals. This assumption introduces a serial order problem for speech. It is also at odds with children's speech. In particular, child phonology and timing control suggest holistic speech plans, and so the hypothesis of whole word production. This hypothesis solves the serial (...) order problem by avoiding it. When the same solution is applied to adult speech the problem becomes how to explain the development of highly intelligible speech. This is the problem addressed here. A modeling approach is used to demonstrate how perceptual-motor units of production emerge over developmental time with the perceptual-motor integration of holistic speech plans that are also phonological representations; the specific argument is that perceptual-motor units are a product of trajectories (nearly) crossing in motor space. The model, which focuses on the integration process, defines the perceptual-motor map as a set of linked pairs of experienced perceptual and motor trajectories. The trajectories are time-based excursions through speaker-defined perceptual and motor spaces. By hypothesis, junctures appear where motor trajectories near or overlap one another in motor space when the shared (or extremely similar) articulatory configurations in these regions are exploited to combine perceptually-linked motor paths along different trajectories. Junctures form in clusters in motor space. These clusters, along with their corresponding (linked) perceptual points, represent perceptual-motor units of production, albeit at the level of speech motor control only. The units serve as pivots in motor space during speaking; they are points of transition from one motor trajectory to another along perceptually-linked paths that are selected to produce best approximations of whole word targets.

While the rate of Internet use among the older population in China is rapidly increasing, the outcomes associated with Internet use remain largely unexplored. Currently, there are contradictory findings indicating that Internet use is sometimes positively and sometimes negatively associated with older adults’ subjective well-being. Therefore, we examined the associations between different types of Internet use, social networks, and loneliness among Chinese older adults using data from the Chinese Longitudinal Ageing Society Survey. Internet use was classified as interpersonal communication and (...) information acquisition, and social networks were divided into family and friendship ties. The results showed that both interpersonal communication and information acquisition were associated with lower loneliness. Interpersonal communication can increase social networks, and family ties have a mediating effect on the association between Internet use for interpersonal communication and loneliness. Although information acquisition can directly decrease loneliness in older adults, it can also damage existing social networks and further increase loneliness. Family ties act as a suppressor in the association between Internet use for information acquisition and loneliness. Our study further discusses important implications for improving the subjective well-being of older adults in the digital era, based on the empirical findings. (shrink)

Cross-situational word learning, like any statistical learning problem, involves tracking the regularities in the environment. However, the information that learners pick up from these regularities is dependent on their learning mechanism. This article investigates the role of one type of mechanism in statistical word learning: competition. Competitive mechanisms would allow learners to find the signal in noisy input and would help to explain the speed with which learners succeed in statistical learning tasks. Because cross-situational word learning provides information at multiple (...) scales—both within and across trials/situations—learners could implement competition at either or both of these scales. A series of four experiments demonstrate that cross-situational learning involves competition at both levels of scale, and that these mechanisms interact to support rapid learning. The impact of both of these mechanisms is considered from the perspective of a process-level understanding of cross-situational learning. (shrink)

How linguistic structures evolve so as to become easier to process is addressed by Isbilen and Christiansen for the Now‐or‐Never bottleneck. The authors suggest that this fundamental challenge in language processing is coped with by rapid compression of the transient linguistic input into chunks then to be passed on. As linguistic structures that can be chunked more easily tend to stabilize and proliferate, language evolves to fit learners’ cognitive capabilities.

The political make-up of the contemporary world changes with such rapidity that few attempts have been made to consider with adequate care, the nature and value of the concept of sovereignty. What exactly is meant when one speaks about the acquisition, preservation, infringement or loss of sovereignty? This book revisits the assumptions underlying the applications of this fundamental category, as well as studying the political discourses in which it has been embedded. Bringing together historians, constitutional lawyers, political philosophers and (...) experts in international relations, Sovereignty in Fragments seeks to dispel the illusion that there is a unitary concept of sovereignty of which one could offer a clear definition. This book will appeal to scholars and advanced students of international relations, international law and the history of political thought. (shrink)

Here, we describe how Casas Grandes Medio period (AD 1200 to 1450) shamanic practices of the North American Southwest used tobacco shamanism, a ritual stance called the Tennessee Diviner (TD) posture, and cultural expectations to generate trance experiences of soul flight and divination. We introduce a conceptual model that holds that specific trance experiences are the emergent result of human minds interacting with additional factors including entheogens, cultural expectations, physiological states, postures/movement, and sound/stimulation. Experimental and ethnographic evidence indicates initiating trance (...) with either tobacco intoxication or the TD posture accompanied with a rapidly beating drum or rattle corresponds with perceptions of soul flight, transformation, and divination/information acquisition. Both have similar results but pairing them together as they were during the Medio period likely helped ensure the culturally desired trance experiences. This practice of mutually reinforcing factors was likely part of tobacco‐based shamanism found in other New World cultures as well. We suggest our general model can be applied to other contexts to examine how various aspects of trance induction interact to produce the cultural patterns (and resulting cosmological and spiritual frameworks) anthropologists have documented in other cultures.

Virtuosity in music performance is often associated with fast, precise, and efficient sound-producing movements. The generation of such highly skilled movements involves complex joint and muscle control by the central nervous system, and depends on the ability to anticipate, segment, and coarticulate motor elements, all within the biomechanical constraints of the human body. When successful, such motor skill should lead to what we characterize as fluency in musical performance. Detecting typical features of fluency could be very useful for technology-enhanced learning (...) systems, assisting and supporting students during their individual practice sessions by giving feedback and helping them to adopt sustainable movement patterns. In this study, we propose to assess fluency in musical performance as the ability to smoothly and efficiently coordinate while accurately performing slow, transitionary, and rapid movements. To this end, the movements of three cello players and three drummers at different levels of skill were recorded with an optical motion capture system, while a wireless electromyogrphy (EMG) system recorded the corresponding muscle activity from relevant landmarks. We analyze the kinematic and coarticulation characteristics of these recordings separately and then propose a combined model of fluency in musical performance predicting music sophistication. Results suggest movements from expert performers' are characterized by consistently smooth strokes and scaling of muscle phasic coactivation. The explored model of fluency as function of movement smoothness and coarticulation patterns was shown to be limited by the sample size but serves as a proof of concept. Results from this study show the potential of a technology-enhanced objective measure of fluency in musical performance, which could lead to improved practices for aspiring musicians, instructors, and researchers.

Self-relevance has been demonstrated to impair instrumental learning. Compared to unfamiliar symbols associated with a friend, analogous stimuli linked with the self are learned more slowly. What is not yet understood, however, is whether this effect extends beyond arbitrary stimuli to material with intrinsically meaningful properties. Take, for example, stimulus valence an established moderator of self-bias. Does the desirability of to-be-learned material influence self-learning? Here, in conjunction with computational modelling (i.e. Reinforcement Learning Drift Diffusion Model analysis), a probabilistic selection task (...) was used to establish if and how stimulus valence (i.e. desirable/undesirable posters) impacts the acquisition of knowledge relating to object-ownership (i.e. owned-by-self vs. owned-by-friend). Several interesting results were observed. First, undesirable posters were learned more rapidly for self compared to friend, an effect that was reversed for desirable posters. Second, learning rates were accompanied by associated differences in reward sensitivity toward desirable and undesirable choice selections as a function of ownership. Third, decisional caution was greater for self-relevant (vs. friend relevant) responses. Collectively, these findings inform understanding of self-function and how valence and stimulus relevance mutually influence probabilistic learning. (shrink)

Within the next few years scientists will almost certainly have pieced together a broad map of the major gene locations on the twenty‐three human chromosomes. The rapid unfolding of this new knowledge raises new questions: What limits, if any, should be imposed on its acquisition? Who should control the wealth of resulting data? How should it be used? If, because of a deep‐seated need for certitude, many persons are likely to perceive a positive gene probe test as an (...) indicator of biologic destiny, probes may acquire a misleading status in our medical armamentarium.

As the national awareness of health keeps deepening, online health communities have achieved rapid development. Users’ participation is critically important to the sustainable development of OHCs. Nevertheless, users usually lack the motive for participation. Based on the social capital theory, this research examines factors influencing users’ participation in OHCs. The purpose of this research is to find out decisive factors that influence users’ participation in OHCs, enrich the understanding of users’ participation in OHCs, and help OHCs address the issue (...) of sustainable development. The research model was empirically tested using 1277 responses from an online survey conducted in China. Data was analyzed using the structural equation modeling. We found informational support and emotional support to have significant direct effects over the structural capital, relational capital and cognitive capital of OHCs. Meanwhile, it is observed that relational capital and cognitive capital degree have a significant influence on knowledge acquisition and knowledge contribution of OHCs. For researchers this study provides a basis for further refinement of individual models of users’ participation. For practitioners, understanding the social capital is crucial to users’ knowledge acquisition and knowledge contribution that achieve high participation in OHCs. (shrink)

Signed and written languages are intimately related in proficient signing readers. Here, we tested whether deaf native signing beginning readers are able to make rapid use of ongoing sign language to facilitate recognition of written words. Deaf native signing children received prime target pairs with sign word onsets as primes and written words as targets. In a control group of hearing children, spoken word onsets were instead used as primes. Targets either were completions of the German signs or of (...) the spoken word onsets. Task of the participants was to decide whether the target word was a possible German word. Sign onsets facilitated processing of written targets in deaf children similarly to spoken word onsets facilitating processing of written targets in hearing children. In both groups, priming elicited similar effects in the simultaneously recorded event related potentials, starting as early as 200 ms after the onset of the written target. These results suggest that beginning readers can use ongoing lexical processing in their native language – be it signed or spoken – to facilitate written word recognition. We conclude that intimate interactions between sign and written language might in turn facilitate reading acquisition in deaf beginning readers. (shrink)

The de‐repression of transposable elements (TEs) in mammalian genomes is thought to contribute to genome instability, inflammation, and ageing, yet is viewed as a cell‐autonomous event. In contrast to mammalian cells, prokaryotes constantly exchange genetic material through TEs, crossing both cell and species barriers, contributing to rapid microbial evolution and diversity in complex communities such as the mammalian gut. Here, it is proposed that TEs released from prokaryotes in the microbiome or from pathogenic infections regularly cross the kingdom barrier (...) to the somatic cells of their eukaryotic hosts. It is proposed this horizontal transfer of TEs from microbe to host is a stochastic, ongoing catalyst of genome destabilization, resulting in structural and epigenetic variations, and activation of well‐evolved host defense mechanisms contributing to inflammation, senescence, and biological ageing. It is proposed that innate immunity pathways defend against the horizontal acquisition of microbial TEs, and that activation of this pathway during horizontal transposon transfer promotes chronic inflammation during ageing. Finally, it is suggested that horizontal acquisition of prokaryotic TEs into mammalian genomes has been masked and subsequently under‐reported due to flaws in current sequencing pipelines, and new strategies to uncover these events are proposed.

What is the nature of the underlying representations and mechanisms which allow very young children to acquire the words and structures of their native language? Our research looks especially at children between the ages of 3-5 when language acquisition still proceeds rapidly and uses multiple methodologies, including act-out tasks, truth value judgment tasks, and elicited imitation and production tasks.

We explore the relationship between first language attrition and language dominance, defined here as the relative availability of each of a bilingual’s languages with respect to language processing. We assume that both processes might represent two stages of one and the same phenomenon (Köpke, 2018; Schmid & Köpke, 2017). While many researchers agree that language dominance changes repeatedly over the lifespan (e.g. Silva-Corvalan & Treffers-Daller, 2015), little is known about the precise time scales involved in dominance shifts and attrition. We (...) investigated such time scales in a longitudinal case study of pronominal subject production by a near-native L2-German (semi-null subject/topic-drop but non-pro-drop) and L1-Bulgarian (pro-drop) bilingual speaker with 15 years of residence in Germany. This speaker’s spontaneous speech showed a significantly higher rate of overt subjects (OS) in her L1 than the controls’ rates when tested in Germany. After a three-week L1 reexposure in Bulgaria, however, attrition effects disappeared and the OS rate fell within the monolinguals’ range (Genevska-Hanke, 2017). The findings of this first investigation were now compared to those of a second investigation five years later, involving data collection in both countries. The results show that after 15 years of immigration, no further attrition was attested and OS production remained monolingual-like for data collection in both language environments. The discussion focuses on the factors that are likely to explain these results. First, these show that attrition and language dominance are highly dependent on immediate language use context and change rapidly when the language environment is modified. Additionally, the data obtained after L1 reexposure illustrate that time scales involved in dominance shift or attrition are much shorter than previously thought. Second, the role of age of acquisition in attrition has repeatedly been acknowledged. The present study demonstrates that attrition of a highly entrenched L1 is a phenomenon affecting language processing only temporarily and that it is likely to regress quickly after reexposure or return to balanced L1 use. The discussion suggests that dominance shift and attrition probably involve similar mechanisms and are influenced by the same external factors, showing that both may be different steps of the same process.

Much of Edmonton’s municipal past lacked any overarching development plan. Once such absentee municipal planning gave way to more concrete forms of municipal planning in terms of shaping the urban environment, conflicting goals soon emerged. Between 1949 and the early 1980s a conflict in planning goals within both the Edmonton District Planning Commission and the City of Edmonton, at this time governed with a commission board became apparent. Often this conflict played out in Edmonton’s river valley with competing visions of (...) preservation and freeway construction. River valley neighborhoods were threatened with land acquisition policies that viewed the river valley as the sole domain of parkland. Concurrently, those neighborhoods and much of the river valley were also threatened by the Metropolitan Edmonton Transportation Study. Citizen engagement in an otherwise politically apathetic city led to its demise, although the threat of large-scale removal of river valley parks and homes throughout the city loomed for some time. The period between 1949 and 1983 represents a period in Edmonton’s history where environmental protection policy clashed with transportation policy that advocated for the wholesale destruction of the river valley and countless homes. It is this conflict that led to increased political awareness that directly contributed to the demise of the METS scheme and gave rise to renewed support for river valley protection while making rapid transit a possibility for Edmonton.

Light sheet microscopy is an easy to implement and extremely powerful alternative to established fluorescence imaging techniques such as laser scanning confocal, multi‐photon and spinning disk microscopy. By illuminating the sample only with a thin slice of light, photo‐bleaching is reduced to a minimum, making light sheet microscopy ideal for non‐destructive imaging of fragile samples over extended periods of time. Millimeter‐sized samples can be imaged rapidly with high resolution and high depth penetration. A large variety of instruments have been developed (...) and optimized for a number of different samples: Bessel beams form thin light sheets for single cells, and selective plane illumination microscopy (SPIM) offers multi‐view acquisition to image entire embryos with isotropic resolution. This review explains how light sheet microscopy involves a conceptually new microscope design and how it changes modern imaging in biology. (shrink)

The life we considered normal was disrupted due to measures taken to limit the spread of the novel coronavirus. Quarantine, isolation, social distancing, and community containment have influenced consumer behavior and contributed to the rapid development of e-commerce. In pandemic times, even those unfamiliar with the online environment have had to adapt and make acquisitions in this new manner. Hence, we focused our research on measuring the perception of consumers on how the restrictive measures imposed to limit the spread (...) of the COVID-19 virus had influenced their decision to buy a product or service from the online environment, given that purchases are highly subjective and influenced by cumulative effects of economic, social, psychological and behavioral factors. Our paper comes with additional insights from the literature. It adds empirical evidence that reveals that the number of transactions and the value per transaction increased during the COVID-19 pandemic and highlights that online purchases will continue as such even after the pandemic.
