On the early development of aspect in greek and russian child language, a comparative analysis
(2003)
The category of aspect is grammaticized in both Greek and Russian opposing perfective and imperfective verb forms in all inflectional categories except the nonpast (‘present’). Despite these similarities there are important differences in the way the aspectual systems function in the two languages. While in Greek nearly all verbs oppose a perfective to a given imperfective grammatical form, Russian aspect is more strongly lexicalized with pairs of imperfective and perfective lexemes not only differing aspectually, but also as far as their lexical meanings are concerned. This is especially true of perfective verbs formed by prefixes as compared to their imperfective bases. Thus, in pairs of prefixed and unprefixed dynamic verbs, the derived prefixed (perfective) member has a telic meaning while its unprefixed (imperfective) counterpart is atelic (e.g. sjest’ (PFV) ‘to eat up’ vs. jest’ (IPF) ‘to eat’). Such derived perfective verbs may in turn be “secondarily” imperfectivized by suffixation furnishing the only “true” perfective/imperfective pairs of verbs (e.g. sjest’ (PFV) ‘to eat up’ vs. sjedat’ (IPF) ‘to eat up’ (iterative)). “Secondary” imperfectives do not occur in our child data.
In this pilot study, we will analyze the tense-aspect-mood forms of the 20 most frequent verbs with equivalent meanings occurring in the longitudinal audiotaped data of a Greek and a Russian boy between 2;1 and 2;3 (their entire lexical inventories comprise approx. 100 verbs each).
We adopt a constructivist perspective on the development of aspect in Greek and Russian child language and will show that in spite of a broad inventory of imperfective and perfective verb forms to be found in the speech of both children aspect has not yet developed into a generalized grammatical category, but is strongly dependent on aktionsart (stative/dynamic, telic/atelic) in both languages. While this results in a strong preference for perfective verb forms of telic verbs and of imperfective forms of atelic ones in the speech of the Greek boy, the Russian child tends to use the unmarked members.
In this squib, I want to argue that the morphological structure of words is, at least to some extent, motivated. As an example I have choosen the partonomic (and for the less part taxonomic) nomenclature of the human body. While important work by Brown et alii (1973), Anderson (1978) and Schladt (1997) exists on this topic, these analyses focus on the conceptualization of body-parts and their semantics, but not on their morphological representation.
In the following, I want to check two predictions about the morphological complexity of lexical items denoting parts of the human body. The first assumption is that the most canonical body-parts are always expressed by mono-lexematic items. The second one consists in the assumption that body-parts of the lowest levels in the hierarchy are always morphologically complex. A set of six body-parts has been analysed in 27 languages. The set consists of two canonical (HEAD and EAR) and of one from the lowest level of the hierarchy (TOENAIL). For this I have adopted a sample from Schladt (1997) and a small one compiled by myself
This paper reviews research on English past-tense acquisition to test the validity of the single mechanism model and the dual mechanism model, focusing on regular-irregular dissociation and semantic bias. Based on the review, it is suggested that in L1 acquisition, both regular and irregular verbs are governed by semantics; that is, early use of past tense forms are restricted to achievement verbs—regular or irregular. In contrast, some L2 acquisition studies show stronger semantic bias for regular past tense forms (e.g., Housen, 2002, Rohde, 1996). It is argued that L1 acquisition of the past-tense morphology can be accounted for more adequately by the single-mechanism model.
In my Cahuilla Grammar (Seiler 1977:276-282) and in a subsequent paper (Seiler 1980:229-236) I have drawn attention to the fact that many kin terms in this language, especially those that have a corresponding reciprocal term in the ascending direction – like niece or nephew in relation to aunt – occur in two expressions of quite different morphological shape. The following remarks are intended to furnish an explanation of this apparent duplicity.
The focus of the present paper is on the difference between English and German learners‘ use of perfectivity and imperfectivity. The latter is expressed by means of suffixation (suffix -va-). In contrast, perfectivity is encoded either by suffixation (-nou-) or by prefixation (twenty different prefixes that mostly modify not only aspectual but also lexical properties of the verb).
In the native Czech data set, there is no significant difference between the number of imperfectively and perfectively marked verb forms. In the English data, imperfectively and perfectively marked verb forms are equally represented as well. However, German learners use significantly more perfective forms than English learners and Czech natives. When encoding perfectivity in Czech, German learners prefer to use prefixes to suffixes. Overall, English learners in comparison to German learners encode more perfectives by means of suffixation than prefixation.
These results suggest that German learners of Czech focus on prefixes expressing aspectual and lexical modification of the verb, while English learners rather pay attention to the aspectual opposition between perfective and imperfective. In a more abstract way, the German learner group focuses on the operations carried out on the left side from the verb stem while the English learner group concentrates on the operations performed on the right side qfrom the verb stem.
This sensitivity can be to certain degree motivated by the linguistic devices of the corresponding source languages: English learners of Czech use imperfectives mainly because English has marked fully grammatical form for the expression of imperfective aspect – the progressive -ing form. German learners, on the other hand, pay in Czech more attention to the prefixes, which like in German modify the lexical meaning of the verb. In this manner, Czech prefixes used for perfectivization function similar to the German verbal prefixes (such as ab-, ver-) modifying Aktionsart.
Although verb forms encoding focus were recorded in various Bantu languages during the twentieth century it was not until the late 1970's that they became the centre of serious attention, starting with the work of Hyman and Watters. In the last decade this attention has grown. While focus can be expressed variously, this paper concentrates largely on its morphological, partly on its tonal expression. On the basis of morphological and tonal behaviour, it identifies four blocks of languages, representing less than a third of all Bantu languages: those with metatony, those with a binary constituent contrast between verb ("disjunctive") and post-verbal ("conjunctive") focus, those with a three-way contrast, and those with verb initial /ni-/. Following Güldemann's lead, it is shown there is a fairly widespread grammaticalisation path whereby focus markers may come to encode progressive aspect, then present tense. Many Bantu languages today have a pre-stem morpheme /a/ 'non-past' and it is hypothesized that many of these /a/, which are otherwise hard to explain historically, may derive from an older focus marker.
This paper reports results from a series of experiments that investigated whether semantic and/or syntactic complexity influences young Dutch children’s production of past tense forms. The constructions used in the three experiments were (i) simple sentences (the Simple Sentence Experiment), (ii) complex sentences with CP complements (the Complement Clause Experiment) and (iii) complex sentences with relative clauses (the Relative Clause Experiment). The stimuli involved both atelic and telic predicates. The goal of this paper is to address the following questions.
Q1. Does semantic complexity regarding temporal anchoring influence the types of errors that children make in the experiments? For example, do children make certain types of errors when a past tense has to be anchored to the Utterance Time (UT), as compared to when it has to be anchored to the matrix topic time (TT)?
Q2. Do different syntactic positions influence children’s performance on past-tense production? Do children perform better in the Simple Sentence Experiment compared to complex sentences involving two finite clauses (the Complement Clause Experiment and the Relative Clause Experiment)? In complex sentence trials, do children perform differently when the CPs are complements vs. when the CPs are adjunct clauses? (Lebeaux 1990, 2000)
Q3. Do Dutch children make more errors with certain types of predicate (such as atelic predicates)? Alternatively, do children produce a certain type of error with a certain type of predicates (such as producing a perfect aspect with punctual predicates)? Bronckart and Sinclair (1973), for example, found that until the age of 6, French children showed a tendency to use passé composé with perfective events and simple present with imperfective events; we will investigate whether or not the equivalent of this is observed in Dutch.
Our results indicate some differences in the use of aspect between French and Croatian speaking children. In Croatian language children always manage to keep the appropriate aspect, unlike French children. However, the imperfective aspect seems to be better acquired in French children than the perfective aspect. The perfective aspect, the marked form both in French as well as in Croatian, is related to the lexical meaning of the verbs. The acquisition of the Aktionsart in both languages seems to be more a matter of semantics than of morphology. Furthermore, our data suggest the existence of a specific developmental trend in the use of Aktionsart (intensive, iterative and inchoative), which is similar for children speaking Slavic and Romanic languages.
The current study investigates the relation between aspect and particle verbs in the acquisition of English. Its purpose is to determine whether children associate telicity, as argued in previous studies, or rather perfectivity, which entails completion of a telic situation, with their early particle verb use. The study analyzes naturalistic data of four monolingual children between 1;6 and 3;8 from CHILDES acquiring English as their first language. On the one hand, it finds that children use both –ed and irregular perfective morphology with simplex verbs before particle verbs. They further use imperfective before perfective morphology with particle verbs. These findings suggest that there is no correlation between telic particle verbs and perfective morphology, as would have been predicted on an account which claims that lexical aspect of predicates guides the acquisition of grammatical aspect (Olsen & Weinberg 1999). On the other hand, the study finds that the children’s particle verbs denote telic situations from early on, but not half of them were used to refer to situations that are also completed. This finding questions analyses which claim that, at an initial stage, children will only interpret predicates as telic if they refer to situations that are at the same time completed. Completion information is not necessary for children in order to use particle verbs correctly for telic situations, as would have been predicted on an extended account along the lines of Wagner (2001). As a conclusion, it is suggested that the divergent findings result from a difference in methodology. While restrictions of perfective and imperfective morphology to particular classes of lexical aspect pertain to the production of grammatical aspect morphology, perfective and imperfective viewpoints on situations pertain to the level of interpretation of telic and atelic situations.
