Children have difficulty comprehending novel verbs in the double object dative as compared to the prepositional dative. We explored this pattern with 3 and 4 year olds. In Experiment 1, we replicated the documented difficulty with the double object frame, even though we provided more contextual support. In Experiment 2, we tested a novel hypothesis that children would comprehend novel verbs in, and generalize them to, the double object frame if they were first familiarized to the verbs in the prepositional (...) frame. They did, suggesting that part of their difficulty with the double object frame is due to uncertainty about a new verb's semantic/syntactic properties, information that the easy-to-comprehend prepositional frame provides. The benefits of training were short-lived, however; children again struggled after a 2-h delay. The results are discussed in the context of mechanisms underlying verb acquisition. (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.

This study adjudicates between two opposing accounts of morphological productivity, using English past-tense as its test case. The single-route model posits that both regular and irregular past-tense forms are generated by analogy across stored exemplars in associative memory. In contrast, the dual-route model posits that regular inflection requires use of a formal “add -ed” rule that does not require analogy across regular past-tense forms. Children saw animations of an animal performing a novel action described with a novel verb. Past-tense (...) forms of novel verbs were elicited by prompting the child to describe what the animal “did yesterday.” Collapsing across age group, the likelihood of a verb being produced in regular past-tense form was positively associated with the verb's similarity to existing regular verbs, consistent with the single-route model only. Results indicate that children's acquisition of the English past-tense is best explained by a single-route analogical mechanism that does not incorporate a role for formal rules. (shrink)

Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection. Such difficulties are less apparent in languages with rich verb morphology like Spanish and Italian. Here we show how these differential profiles can be understood in terms of an interaction between properties of (...) the input language, and the child's ability to learn predictive relations between linguistic elements that are separated within a sentence. We apply a simple associative learning model to sequential English and Spanish stimuli and show how the model's ability to associate cues occurring earlier in time with later outcomes affects the acquisition of verb inflection in English more than in Spanish. We relate this to the high frequency of the English bare form (which acts as a default) and the English process of question formation, which means that (unlike in Spanish) bare forms frequently occur in third‐person singular contexts. Finally, we hypothesize that the pro‐drop nature of Spanish makes it easier to associate person and number cues with the verb inflection than in English. Since the factors that conspire to make English verb inflection particularly challenging for learners with weak sequential learning abilities are much reduced or absent in Spanish, this provides an explanation for why learning Spanish verb inflection is relatively unaffected in children with DLD.

This paper investigates frequency effects in the L2 acquisition of the catenative verb construction by German learners of English from a usage-based perspective by presenting findings from two experimental studies and a complementary corpus study. It was examined if and to what extent the frequency of the verb in the catenative verb construction affects the choice of the target-like complement type and if the catenative verb construction with a to-infinitive complement, which is highly frequent in (...) English, is more accurately acquired and entrenched than the less frequent variant with an -ing complement. In all three studies, the more frequent construction with a to-infinitive yielded higher numbers of target-like complement choices. Furthermore, it was shown that the verb’s faithfulness to the construction made a significant prediction of a target-like complement preference. It is argued that a higher faithfulness promotes a target-like entrenchment of the construction and motivates a taxonomic generalisation across related exemplars. Furthermore, the results provide support for the idea that the mental representation of language is comprised of item-specific as well as more abstract schema knowledge, where frequency determines the specificity with which the construction is entrenched.

Languages encode motion in strikingly different ways. Languages such as English communicate the manner of motion through verbs (e.g., roll, pop), while languages such as Greek often lexicalize the path of motion in verbs (e.g., ascend, pass). In a set of studies with English- and Greek-speaking adults and 5-year-olds, we ask how such lexical constraints are combined with structural cues in hypothesizing meanings for novel motion verbs. We show that lexicalization biases generate different interpretations of novel motion verbs across ages (...) and languages; furthermore, they generalize to the domain of caused motion. Crucially, these language-specific effects interact with universal mappings between syntactic structure and semantic content, and these interactions are respected by both adults and young children.

Mental-content verbs such as think, believe, imagine and hope seem to pose special problems for the young language learner. One possible explanation for these diYculties is that the concepts that these verbs express are hard to grasp and therefore their acquisition must await relevant conceptual development. According to a diVerent, perhaps complementary, proposal, a major contributor to the diYculty of these items lies with the informational requirements for identifying them from the contexts in which they appear. The experiments reported (...) here explore the implications of these proposals by investigating the contribution of observational and linguistic cues to the acquisition of mental predicate vocabulary. We Wrst demonstrate that particular observed situations can be helpful in prompting reference to mental contents, speciWcally, contexts that include a salient and/or unusual mental state such as a false belief. We then compare the potency of such observational support to the reliability of alternate or concomitant syntactic information (e.g., sentential complementation) in tasks where both children and adults are asked to hypothesize the meaning of novel verbs. The Wndings support the eYcacy of false belief situations for increasing the saliency of mental state descriptions, but also show that.. (shrink)

This study aims to disentangle the often-confounded effects of input frequency and morphophonological complexity in the acquisition of inflection, by focusing on simple and complex verb forms in Japanese. Study 1 tested 28 children aged 3;3–4;3 on stative and simple past forms, and Study 2 tested 30 children aged 3;5–5;3 on completive and simple past forms, with both studies using a production priming paradigm. Mixed effects models for children's responses were built to test the prediction that children's (...) class='Hi'>verb use is explained by the relative bias in input frequency between the two inflectional forms. Although Study 1 did not show a significant effect of input bias, Study 2, which corrected for this problem, yielded the predicted relationship. These findings suggest that input frequency effects, at the level of different inflectional forms of the same verb stem, hold even after controlling for morphophonological complexity. (shrink)

There is growing evidence that words that are acquired early in life are processed faster and more accurately than words acquired later, even by adults. As neuropsychological and neuroimaging studies have implicated different brain networks in the processing of action verbs and concrete nouns, the present study was aimed at contrasting reaction times to early and later-acquired action verbs and concrete nouns, in order to determine whether effects of word learning age express differently for the two types of words. Our (...) results show that while word frequency affected both types of words in the same way, distinct learning age effects were observed for action verbs and concrete nouns. A further experiment specified that this difference was observed for verbs describing actions belonging to the human motor repertoire, but not for verbs denoting actions past this repertoire (e.g., to neigh). We interpret these data within a recently emerging framework according to which language processing is associated with sensory motor programs. (shrink)

It is well known that languages differ in how they encode motion. Languages such as English use verbs that communicate the manner of motion (e.g., climb, float), while languages such as Greek often encode the path of motion in verbs (e.g., advance, exit). In two studies with English- and Greek-speaking adults and 5-year-olds, we ask how such lexical constraints are used in combination with structural cues in hypothesizing meanings for novel motion verbs cross-linguistically. We show that lexicalization biases affect the (...) interpretations of motion verbs in both young children and adults across different languages; furthermore, their scope of application is larger than previously thought, since they also extend to the domain of caused motion events. Crucially, we find that the language-specific effects of such biases interact with universal mappings between syntactic structure and semantic content. Finally, we demonstrate that the combined effects of lexical and structural cues shift non-linguistic biases observed during event categorization: even though speakers of English and Greek share non-linguistic preferences in categorizing spontaneous and caused motion, they focus on different components of motion events when building hypotheses about the meaning of novel motion verbs.

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)

Many studies show a developmental advantage for transitive sentences with familiar verbs over those with novel verbs. It might be that once familiar verbs become entrenched in particular constructions, they would be more difficult to understand (than would novel verbs) in non-prototypical constructions. We provide support for this hypothesis investigating German children using a forced-choice pointing paradigm with reversed agent-patient roles. We tested active transitive verbs in study 1. The 2-year olds were better with familiar than novel verbs, while the (...) 2½-year olds pointed correctly for both. In study 2, we tested passives: 2½-year olds were significantly below chance for familiar verbs and at chance for novel verbs, supporting the hypothesis that the entrenchment of the familiar verbs in the active transitive voice was interfering with interpreting them in the passive voice construction. The 3½-year olds were also at chance for novel verbs but above chance with familiar verbs. We interpret this as reflecting a lessening of the verb-in-construction entrenchment as the child develops knowledge that particular verbs can occur in a range of constructions. The 4½-year olds were above chance for both familiar and novel verbs. We discuss our findings in terms of the relative entrenchment of lexical and syntactic information and to interference between them. (shrink)

Verb extension is a crucial gauge of the acquisition of verb meaning. In English, studies suggest that young children show conservative extension. An important test of whether an early conservative extension is a general phenomenon or a function of the input language is made possible by Chinese, a language in which verbs are more frequent and acquired earlier. This study tested whether 3-year-old Chinese children extended a group of familiar verbs that specify various ways to carry objects. (...) Shown videos that portrayed typical, mid-typical, or atypical carrying actions, children were asked to judge whether they were examples of specific Chinese carry verbs. Children’s verb extensions were mostly limited to typical exemplars, suggesting that an early conservative extension may be universal. Furthermore, extension breadth was related to the onset of verb production: verbs acquired earlier elicited more extension judgments than those acquired later. (shrink)

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.

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)

In this study, we test a number of predictions concerning children's knowledge of the transitive Subject-Verb-Object (SVO) construction between two and three years on one child (Thomas) for whom we have densely collected data. The data show that the earliest SVO utterances reflect earlier use of those same verbs, and that verbs acquired before 2;7 show an earlier move towards adult-like levels of use in the SVO construction and in object argument complexity than later acquired verbs. There is not (...) a close relation with the input in the types of subject and object referents used, nor a close adherence to Preferred Argument Structure (PAS) before 2;7, but both early and late acquired verbs show a simultaneous move towards PAS patterns in selection of referent type at 2;9. The event semantics underpinning early transitive utterances do not straightforwardly fit prototype (high or inalienable) notions of transitivity, but rather may reflect sensitivity to animacy and intentionality in a way that mirrors the input. We conclude that children's knowledge of the transitive construction continues to undergo significant development between 2;0 and 3;0, reflecting the gradual abstraction and integration of the SVO and VO constructions, verb semantics, discourse pragmatics, and the interactions between these factors. These factors are considered in the context of a prototype for the transitive construction. (shrink)

The set of English modal verbs is widely recognized to communicate two broad clusters of meanings: epistemic and root modal meanings. A number of researchers have claimed that root meanings are acquired earlier than epistemic ones; this claim has subsequently been employed in the linguistics literature as an argument for the position that English modal verbs are polysemous (Sweetser, 1990). In this paper I offer an alternative explanation for the later emergence of epistemic interpretations by linking them to the development (...) of the child’s theory of mind (Wellman, 1990); if correct, this hypothesis might have important implications for the shape of the semantics of modal verbs.

The apparent very close similarity between the learning of the past tense by Adam and the Plunkett and Marchman model is exaggerated by several misleading comparisons--including arbitrary, unexplained changes in how graphs were plotted. The model's development differs from Adam's in three important ways: Children show a U-shaped sequence of development which does not depend on abrupt changes in input; U-shaped development in the simulation occurs only after an abrupt change in training regimen. Children overregularize vowel-change verbs more than no-change (...) verbs; the simulation overregularizes vowel-change verbs less often than no-change verbs. Children, including Adam, overregularize more than they irregularize; the simulation overregularized less than it irregularized. Interestingly, the RM model--widely criticized as being inadequate--does somewhat better, correctly overregularizing vowel-change verbs more often than no-change verbs, and overregularizing more often than it irregularizes. Although Plunkett and Marchman's (1993) state of the art model incorporated hidden layers and back-propagation, used a more realistic phonological coding scheme, and explored a broader range of parameters than Rumelhart and McClelland's model, their results are farther from psychological reality. It is unknown whether any connectionist model can mimic a child's performance without resorting to unrealistic exogenous changes in the training or input, but it is clear that adding a hidden-layer and back-propagation does not ensure a solution.

Productivity is a central concept in the study of language and language acquisition. As a test case for exploring the notion of productivity, we focus on the noun slots of verb frames, such as __want__, __see__, and __get__. We develop a novel combination of measures designed to assess both the flexibility and creativity of use in these slots. We do so using a rigorously controlled sample of child speech and child directed speech from three English-speaking children between the (...) ages of 2–3 years and their caregivers. We find different levels of creativity and flexibility between the adult and child samples for some measures, for some slots, and for some developmental periods. We discuss these differences in the context of verb frame semantics, conventionality versus creativity and child errors, and draw some tentative conclusions regarding developmental changes in children's early grammatical representations.

The expression of time in languages is universal, whereas the means of expressing time are language specific. Hence the acquisition of a foreign language always involves the acquisition of different linguistic means to express time. Generally the writer/ speaker of a language can apply lexical means to do so, i.e. s/he may apply temporal adverbs, adjectives, substantives, prepositions, conjunctions, particles and verbs, and grammatical means, i.e. tenses, aspects, and syntactical means. Usually time is not conveyed by the use (...) of only one of these means, but by employing several means,1 what makes the acquisition of a second language all the more difficult. (shrink)

This paper investigates the acquisition of residual verb second (V2) in three corpora consisting of data from Norwegian-English bilinguals (Emma, Emily, and Sunniva) in order to determine to what extent these structures are affected by cross-linguistic influence (CLI) from Norwegian V2. The three girls exhibit three different patterns with regard to the relevant constructions. They are very target-like in their use of auxiliaries in the relevant structures. However, when it comes to do-support, Emily and Sunniva are equally target-like, (...) while Emma mainly produces non-target-like structures. These either involve the omission of do, or non-target-like movement of a lexical verb. Furthermore, Emma also allows verb movement across the subject with both lexical verbs and auxiliaries in topicalized structures, suggesting that she has overgeneralized residual V2 across verb types and clause types. Emily, on the other hand, is very target-like in structures involving residual V2 in English, but also allows auxiliaries and dummy-do to move across the subject in topicalized structures, overgeneralizing residual V2 to apply to non-subject-initial declaratives. Finally, Sunniva, is very precocious and very target-like in all the relevant structures, which may be an indication of acceleration due to CLI from Norwegian V2. We discuss these results with reference to language balance, finding that the measures available to us suggest that the differences between the children cannot straightforwardly be explained by language dominance. Instead, we suggest that these results can be accounted for by ambiguity in the English system, leaving the data open to several possible interpretations when acquired in contact with the consistent V2 system in Norwegian. This has several consequences: (i) the three girls’ parsers interpret the input differently, (ii) differences between the three children are qualitative rather than quantitative, and (iii) there has to be some mechanism that ensures that the children can ‘recover’ from these non-target-like grammars. In this paper, we will focus on the first two issues. (shrink)

Learning to map words onto their referents is difficult, because there are multiple possibilities for forming these mappings. Cross-situational learning studies have shown that word-object mappings can be learned across multiple situations, as can verbs when presented in a syntactic context. However, these previous studies have presented either nouns or verbs in ambiguous contexts and thus bypass much of the complexity of multiple grammatical categories in speech. We show that noun word learning in adults is robust when objects are moving, (...) and that verbs can also be learned from similar scenes without additional syntactic information. Furthermore, we show that both nouns and verbs can be acquired simultaneously, thus resolving category-level as well as individual word-level ambiguity. However, nouns were learned more quickly than verbs, and we discuss this in light of previous studies investigating the noun advantage in word learning. (shrink)

L’objectif de ce travail de recherche est d’étudier la distinction formelle entre les locutions verbales et les constructions à verbe support telles qu’elles sont présentées et décrites par les chercheurs travaillant dans le cadre théorique du lexique-grammaire.

Cette étude démontre que, bien que la perception des structures verbales complexes par les apprenants du FL2 soit assez semblable à celle des locuteurs natifs de cette langue, leur production représente un aspect assez difficile pour les premiers.

Entrenchment and schematisation are the two most important cognitive processes in language acquisition. In this article, the role of the two processes, operationalised by token and type frequency, in the production of overgeneralised verb forms in Croatian preschool children is investigated using a parental questionnaire and computational simulation of language acquisition. The participants of the questionnaire were parents of children aged 3;0–5;11 years (n = 174). The results showed that parents of most children (93 %) reported the (...) parallel use of both adult-like and overgeneralised verb forms, suggesting that Croatian-speaking preschool children have not yet fully acquired the verbal system. The likelihood of overgeneralised forms being reported decreases with the age of the children and verb type frequency. The results of the computational simulation show that patterns with a higher type frequency also show a greater preference for the correct form, while lexical items show both learning and unlearning tendencies during the process.

This paper is concerned with the acquisition of certain aspects of the meaning of epistemic modal verbs. Epistemic modals encode the probability, predictability or certainty of the proposition embedded under the modal verb. The sentences in (1) are examples of epistemic modality1.

Noam Chomsky's ideas and work on the human language faculty and how language is acquired opened new territory on which a whole new framework in non‐native language acquisition was established: generative second language acquisition, or GenSLA. Investigating Chomsky's principles and parameters within the GenSLA framework has brought additional and convincing evidence for the essential validity of Chomsky's original insights. This chapter highlights Chomsky's lasting legacy embodied in the GenSLA framework. In addition to interpretation, poverty of the stimulus situations (...) provide an opportunity to test Universal Grammar (UG)‐based knowledge of graded distinctions beyond simple acceptability. The Subjacency Condition was probably the most studied principle of UG in the 1980s and 1990s. Structure dependence is directly demonstrated in languages with auxiliary verb movement to form questions. The Feature Reassembly Hypothesis brought grammatical features reflected in functional categories to the front of GenSLA research. (shrink)

Embodied cognition theory posits that concept representations inherently rely on sensorimotor experiences that accompany their acquisitions. This is well established through concrete concepts. However, it is debatable whether representations of abstract concepts are based on sensorimotor representations. This study investigated the causal role of associated motor experiences that accompany concept acquisition in the involvement of the motor system in the abstract verb processing. Through two experiments, we examined the action–sentence compatibility effect, in the test phase after an increase (...) in motor features during the learning phase for abstract verbs with low motor features or novel words with no conceptual features at all. After associated motor experiences were added in the word learning phase, action–sentence compatibility effect was found in the semantic processing tasks during the test phase for abstract verbs and novel words. This was lacking in the word font color judgment task requiring no semantic processing. Coupled with our previous study, these findings suggest that motor features formed during word learning could causally affect embodiment in the motor system for abstract verbs, and reactivation of motor experiences in abstract verb processing depends on a given task’s demands. Our study supports the view that conceptual representations, even abstract concepts, can be grounded in sensorimotor experiences. (shrink)

How children go about learning the general regularities that govern language, as well as keeping track of the exceptions to them, remains one of the challenging open questions in the cognitive science of language. Computational modeling is an important methodology in research aimed at addressing this issue. We must determine appropriate learning mechanisms that can grasp generalizations from examples of specific usages, and that exhibit patterns of behavior over the course of learning similar to those in children. Early learning of (...) verb argument structure is an area of language acquisition that provides an interesting testbed for such approaches due to the complexity of verb usages. A range of linguistic factors interact in determining the felicitous use of a verb in various constructions—associations between syntactic forms and properties of meaning that form the basis for a number of linguistic and psycholinguistic theories of language. This article presents a computational model for the representation, acquisition, and use of verbs and constructions. The Bayesian framework is founded on a novel view of constructions as a probabilistic association between syntactic and semantic features. The computational experiments reported here demonstrate the feasibility of learning general constructions, and their exceptions, from individual usages of verbs. The behavior of the model over the timecourse of acquisition mimics, in relevant aspects, the stages of learning exhibited by children. Therefore, this proposal sheds light on the possible mechanisms at work in forming linguistic generalizations and maintaining knowledge of exceptions. (shrink)

Usage-based approaches to language hold that we learn multiword expressions as patterns of language from language usage, and that knowledge of these patterns underlies fluent language processing. This paper explores these claims by focusing upon verb–argument constructions such as “V about n.” These are productive constructions that bind syntax, lexis, and semantics. It presents analyses of usage patterns of English VACs in terms of their grammatical form, semantics, lexical constituency, and distribution patterns in large corpora; patterns of VAC usage (...) in child-directed speech and child language acquisition; and investigations of VAC free-association and psycholinguistic studies of online processing. We conclude that VACs are highly patterned in usage, that this patterning drives language acquisition, and that language processing is sensitive to the forms of the syntagmatic construction and their distributional statistics, the contingency of their association with meaning, and spreading activation and prototypicality effects in semantic reference. Language users have rich implicit knowledge of the statistics of multiword sequences. (shrink)

This study investigated the second language processing and acquisition of Chinese temporality, specifically the interaction of grammatical and lexical aspects. An experimental group of 31 English-speaking learners of Chinese and a control group of 29 native speakers of Mandarin Chinese completed an online sentence-picture matching task and an offline translation task. Results from these experiments demonstrated the prototype effect: In aspectual development, perfective aspect started with telic verbs and progressive aspect started with activity verbs, in accordance with the Aspect (...) Hypothesis, both for online processing and offline comprehension. The prototype effect of the grammatical aspect was evident for activity verbs but less so for accomplishment verbs in the L2 group across tasks, and this was explained through language-specific properties and L2 learners’ instructional input. In addition, L2 proficiency and working memory capacity were found to modulate these processes. (shrink)

Talmy divided the world’s languages according to how they express movement. Spanish, a verb-framed language, purportedly constrains the use of motion verbs expressing the manner of movement (such as roll) to contexts in which no spatial boundary is crossed. Previous research suggests that this constraint sometimes does not apply. We report the first large-scale investigation of the constraint and its modulating factors (movement direction, verb type, entering/exiting, Ground size, the preposition used) across different Spanish-speaking communities. A task with (...) open-ended description of animated videos, a sentence interpretation task, and a rating task found that Spanish and Latin American speakers (n = 180 in total) often use manner verbs to describe boundary-crossing situations (especially entering a place), although this is modulated by the preposition following the verb (more with a than en). Better understanding of this constraint in verb-framed languages has applications in, for instance, L2 acquisition research. (shrink)

Bloom's theory of word learning has difficulty accounting for children's verb acquisition. There is no predominant preverbal event concept, akin to the preverbal object concept, to direct children's early event-verb mappings. Children may take advantage of grammatical and linguistic information in verb acquisition earlier than Bloom allows. A distinction between lexical and grammatical learning is difficult to maintain for verb acquisition.

This article reports the structure of associations among 101 common verbs and body parts. The verbs are those typically learned by children learning English prior to 3 years of age. In a free association task, 50 adults were asked to provide the single body part that came to mind when they thought of each verb. Analyses reveal highly systematic and structured patterns of associations that are also related to the normative age of acquisition of the verbs showing a (...) progression from verbs associated with actions by the mouth, to verbs strongly associated with actions by hand and arm, to verbs not so strongly associated with any one body part. The results have implications for proposals about embodied verb meaning and also for processes of early verb learning. (shrink)

Supporters of eliminative connectionism have argued for a pattern association-based explanation of language learning and language processing. They deny that explicit rules and symbolic representations play any role in language processing and cognition in general. Their argument is based to a large extent on two artificial neural network (ANN) models that are claimed to be able to learn the past tenses of English verbs (Rumelhart & McClelland, 1986, Parallel distributed processing, Vol. 2, Cambridge, MA: MIT Press; MacWhinney & Leinbach, 1991, (...) Cognition, 40, 121-157). In this article we critically review Rumelhart and McClelland's as well as MacWhinney and Leinbach's ANN models and conclude that they do not succeed in the assigned task of learning the past tenses of English verbs. In order to answer their challenge to the symbolic processing approach, we present our symbolic pattern associator (SPA)-a general-purpose pattern associator that can learn to associate arbitrary discrete patterns. We carried out several experiments with the SPA using the same set of verbs that was used in MacWhinney and Leinbach's simulation with more realistic training and testing procedures. The SPA outperformed the connectionist models by a wide margin in the accuracy of learning, and successful inductive generalizations to unseen verbs. Our SPA has very natural and psychologically realistic explanations to many psychological effects such as U-shaped learning curve, and is much closer to human subjects in predicting past tense of the pseudo-verbs. In contrast to ANNs, whose internal representations are entirely opaque, the SPA can represent the acquired knowledge in the form of production rules that allow for further higher-level processing and integration, resulting in linguistically realistic associative templates for irregular verbs and production rules for regular verbs. In the light of these findings, we conclude that eliminative connectionists' vision of cognition as simple pattern association and pattern recognition without symbolic representation is inadequate. Pattern association as such does not imply rule-less or cue-based models of language acquisition or of human learning in general. (shrink)

Children show a remarkable degree of consistency in learning some words earlier than others. What patterns of word usage predict variations among words in age of acquisition? We use distributional analysis of a naturalistic corpus of child‐directed speech to create quantitative features representing natural variability in word contexts. We evaluate two sets of features: One set is generated from the distribution of words into frames defined by the two adjacent words. These features primarily encode syntactic aspects of word usage. (...) The other set is generated from non‐adjacent co‐occurrences between words. These features encode complementary thematic aspects of word usage. Regression models using these distributional features to predict age of acquisition of 656 early‐acquired English words indicate that both types of features improve predictions over simpler models based on frequency and appearance in salient or simple utterance contexts. Syntactic features were stronger predictors of children's production than comprehension, whereas thematic features were stronger predictors of comprehension. Overall, earlier acquisition was predicted by features representing frames that select for nouns and verbs, and by thematic content related to food and face‐to‐face play topics; later acquisition was predicted by features representing frames that select for pronouns and question words, and by content related to narratives and object play.

In this paper we investigate whether timing in monolingual acquisition interacts with age of onset and input effects in child bilingualism. Six different morpho-syntactic and semantic phenomena acquired early, late or very late are considered, with their timing in L1 acquisition varying between age 3 (subject-verb agreement) and after age 6 (case marking). Data from simultaneous bilingual children (2L1) whose mean age of onset to German was three months are compared with data from early second language learners (...) of German (eL2) whose mean age of onset to German was 35 months as well as with data from monolingual children. To explore change over time, children were tested twice at the ages of 4;4 years and 5;8 years. The main findings were that 2L1 children had an advantage over their eL2 peers in early acquired phenomena, which disappeared with time, whereas in late acquired phenomena 2L1 and eL2 children did not differ. Moreover, 2L1 children performed like monolingual children in early acquired phenomena but had a disadvantage in the late acquired phenomena with the amount of delay decreasing with time. We conclude that age of onset effects are modulated by effects of timing in monolingual acquisition. Contrary to expectation, input in terms of language dominance, measured as the dominant language used at home, did not affect simultaneous bilingual children’s performance in any of the phenomena. We discuss the implications of our findings for the hypothesis that acquisition of late phenomena is determined by input alone and suggest an alternative concept: the learner’s internal need for time to master a phenomenon, which is determined by its complexity and cross-linguistic robustness.
