Such disorders are of theoretical interest, in that they offer a unique window onto the mechanisms of normal processing. More importantly, they have serious consequences for the people affected, since without verb argument structures it is very difficult to talk about the things that most interest us. By developing a better understanding of verb impairments we should be more able to respond to the dilemma of these individuals, and create more effective and functionally relevant therapies. The Verb Group was set up by researchers and clinicians in University College London and City University to pursue these issues. The group meets in the Department of Human Communication Science at University College London. It is multidisciplinary and intercollegiate, bringing together clinical linguists, psychologists and speech and language therapists. In 2001 the group was awarded an ESRC Seminar Grant. The Verb Group provides a forum for researchers from different disciplines and clinicians with a common interest in: modelling the normal processes that allow us to translate thoughts into words, especially pivotal words such as verbs that determine many aspects of sentence structure. explaining why verbs are particularly difficult for many people with language impairments and modelling the interaction of intact and impaired processing that gives rise to specific patterns of performance. developing theoretically motivated materials for the clinical assessment of verb and sentence processing impairments translating these materials into functionally and therapeutically useful activities that are acceptable and enjoyable for people with language impairments.

For instance, we have supervised a number of student projects investigating whether noun/verb differences in aphasia are primarily syntactic or involve additional semantic factors. Since 2001, we have also staged a programme of seminars on themes related to verb processing. This conference is the culmination of our seminar programme. Our contributors bring a range of clinical and theoretical expertise to the questions of verb processing and can address the topic from both an acquired and developmental perspective. We have no doubt that they will provide us with an extremely stimulating and enjoyable day. We hope that delegates are equally satisfied.

However, it is unclear whether semantic representations or phonological and/or orthographic representations are accessed independently for nouns versus verbs. I will review studies of stroke and dementia that address this question. First, patients with chronic stroke have been reported who have selectively impaired naming of verbs in a single output modality (written or oral); naming of nouns in the affected modality, and naming both nouns and verbs in the other modality were spared. More recently, longitudinal studies of patients with nonfluent primary progressive aphasia show deterioration in oral naming of verbs, before deterioration in oral naming of nouns, and before deterioration in written naming of either. In contrast, fluent primary progressive aphasic patients opposite pattern: deterioration in written naming of nouns, before written naming of verbs and before oral naming either. These cases together provide evidence that some mechanism for accessing orthographic and phonological representations for output is separate for nouns versus verbs. It is unclear from these studies what brain regions are devoted specifically to nouns or verbs. Therefore, we have recently studied written and oral naming and comprehension of nouns and verbs in acute stroke, identifying regions of hypoperfusion (dysfunction) associated with disruption in access to orthographic, phonologic, and semantic representations of verbs. In these studies, hypoperfusion of frontal regions was associated with impaired access to phonological and orthographic representations of verbs, while hypoperfusion of middle temporal gyrus was associated with impaired access to nouns. In contrast, hypoperfusion of left superior temporal gyrus was associated with impaired access to semantic representations of nouns and verbs. These results provide evidence that networks of brain regions recruited in naming nouns versus verbs are only partially overlapping: a frontal component is specific to verbs, a middle temporal component is more essential for nouns.

I will review evidence that verbs differ from nouns across a wide range of phenomena, including memory recall, translatability, semantic mutability, linguistic borrowing, and acquisitional patterns. Based on these differences, I make the following theoretical claim: the open-class -- closed-class distinction is more usefully seen as a continuum with nouns at the open end, grammatical terms at the closed end, and verbs and spatial prepositions in the middle. A further claim is that referential patterns are more variable cross-linguistically for relational terms than for object terms, even in perceptual domains. Thus the meanings of spatial propositions and motion verbs are more linguistically shaped than the meanings of concrete nouns. One corollary is that object names should form the initial point of entry in language acquisition, because concrete nouns can be learned piecemeal, by attaching individual object concepts to words, whereas verbs and other relational terms – including verbs of motion and spatial prepositions -- must be learned as part of a semantic system. A further implication is that verbs should be more closely related to grammar in neural organization than should nouns.

Maria Black The meaning of verbs and other relational terms has often been said to consist of a “core” and a “relational” component (see Marshall, Black and Byng 1999). In this paper, I will argue that we need to revise how we think about “relational meaning” and how we represent it. I will then examine the clinical implications of such a shift. “Relational meaning” has traditionally been represented in terms of list of arguments or thematic roles associated with the verb – its thematic or predicate-argument structure. This conception has been shown to be theoretically inadequate and there is converging evidence from both generative and cognitive linguistics that it should be changed (see Tenny and Pustejovsky 2000; McKoon and Macfarland 2002 among others). . I will claim that “event schemas” or “templates” provide a psycholinguistically and clinically more relevant way of understanding and representing relational meaning (Black & Chiat 2003; McKoon & Macfarland 2002 ). I will argue that event structure is the semantic scaffolding that supports many aspects of sentence processing. In particular, event schemas allow for: a better fit with both syntactic structure and non-linguistic event conceptualization, thus throwing new light on the dynamics of sentence production and its impairments. a basis for thinking about linguistic meaning as an attention guiding system, with different patterns and strengths of attention (Black and Chiat, 2003; Langacker 1998; Talmy 2000) - an aspect of meaning that is almost entirely neglected in clinical practice. a better integration of sentence-level and discourse processes. I will give some specific examples of how event structure and syntactic structure provide "a frame for organizing and managing cognitive costs" (Du Bois 2003) for speakers and listeners. contd/ VENUE: UCL, Dept. of Human Communication Science, 2 Wakefield Street, London WCIN IPF, UK Contact: Cristina Gardini, CLaSS Unit, UCL, Tel.(020)7679 4204/3, email: c.gardini@ucl.ac.uk, Conference website. www.hcs.ucl.ac.uk/class ABSTRACTS References o Black M and Chiat S (2003) Linguistics for Clinicians.

ABSTRACTS Grammatical relations in the acquisition of British Sign Language Gary Morgan, Isabelle Barriere & Bencie Woll Current models of the acquisition of grammatical relations are polarized around two positions. According to those who have proposed bootstrapping hypotheses children’s expression of grammatical relations is best described as productive in that it does not reflect lexically-based learning. In contrast, according to Tomasello (1992, 2000), children’s early multi-word utterances provides evidence for an item-by-item verbspecific expression of grammatical relations This study addresses this issue by investigating the development of verb production by a native British Sign Language (henceforth BSL) signer who has been exposed since infancy to BSL from his parents and older siblings. The aim of the main analysis was to investigate whether the early expression of grammatical expressions by this BSL learner exhibited any evidence of lexicallybased learning versus semantic or syntactic rules. The study of the acquisition of BSL can significantly contribute to this debate: the semantic distinction between eventive and stative meaning in BSL verbs interacts with the transitive/intransitive verb pattern. Transitive eventive verbs (such as ASK, GIVE, PUSH, BITE, HIT) can be inflected for both subject/object agreement while transitive stative verbs (KNOW, LIKE WANT, BELIEVE) cannot. A detailed analysis of the data was developed and each verb was coded for a) presence or absence of agreement marker, b) the semantic relation expressed by the verb, c) the presence and absence of obligatory and optional arguments, d) the thematic roles assigned to the arguments and the semantic features which characterize them, and e) the order in which arguments appear. Our results are discussed in light of the Verb-Island Hypothesis proposed by Tomasello (1992) and cross-linguistics findings obtained on other signed and spoken languages.

Alternatively, the scarcity of verbs is the consequence of these patients’ grammatical deficits and due to verbs being a grammatically complex category in so far that they determine the number and type of noun phrases around them and are marked for tense and agreement. Only the first hypothesis implies a deficit in verb production in single word tasks too. The present study explores the relationship between action naming and sentence production of an agrammatic patient, who, in connected speech, instead of lexical verbs, uses almost exclusively the copula is while he produces many semantically rich nouns, adjectives and adverbials. Although his action picture naming is significantly worse than his object picture naming (62% vs 76%), it seems unlikely that this degree of single verb production deficit could account for the total lack of lexical verbs in his speech. We also show that the patient is able to generate grammatically correct sentences using the present progressive form when provided with a verb or an action picture as cues. This, and his insertion of the copula in most utterances, either in grammatically correct copula constructions, or as (ungrammatical) rudimentary verb substitutes, we think, is evidence that some aspects of his grammar, including the requirement that sentences need verbs is preserved. In a series of experiments we demonstrate that the patient has lost all knowledge related to tense marking not only in production but also in comprehension and grammaticality judgement (while plural production and judgement of argument structure violations remain preserved). We argue that the reason for the lack of verbs in his speech is the unavailability of tense features, including abstract ones that mark morphologically unmarked tense forms in English. This might be because verbs within sentences unmarked for tense would create major ungrammaticality.

Six of the nine subjects had clear Wernicke’s profiles on the Boston Diagnostic Aphasia Examination while the profiles of the other three resembled anomic aphasia. Procedures used in the study included testing single verb comprehension, single word production, sentence comprehension and a grammaticality judgement taken from the Verb and Sentence Test (Bastiaanse, Edwards and Rispens 2002). Additional tests of verb production and sentence judgement, including tests of verb event structure, constructed by the first author, were used to probe additional features of event structure associated with a set of verbs. Results showed a number of apparent anomalies. All subjects had superior understanding of single verbs compared with their ability to produce verbs as single words. Comprehension of verbs as single words was superior to comprehension of sentences. Most strikingly, subjects showed different levels of ability in detecting violations associated with verbs. They were reasonably accurate when asked to identify violations of thematic roles but were poor when asked to identify event structure violations. This series of tests confirmed that verb deficits are complex and, as yet, only partly understood. Despite relatively good comprehension of verbs and an ability to identify thematic role violations, this group of fluent aphasic speakers had difficulties judging whether the telicity required by a verb was correctly given in a sentence. These findings highlight a property of verbs that has not, to date, been explored in aphasic speakers and highlight an area of investigation where it is possible to look at the semantic-syntactic interface within the lexical properties of verbs. By teasing apart the components of verb comprehension we gain further understanding of verb deficits in aphasia. References Bastiaanse, R., Edwards, S. and Rispens, J.

People with aphasia typically have problems with the language of events, both in production and comprehension. Do their event processing problems extend to the non-linguistic domain? An experiment was designed to compare performance on a task which involves linguistic encoding: drawing events from a spoken description, and one in which no overt linguistic encoding is required: drawing events from a visual stimulus. The event types selected for investigation were Caused change of position and Caused change of possession. This paper describes the results of a control study, the purpose of which was to identify some of the attentional factors and procedures used to “package” the events for communication in drawing from the two input modalities. The results revealed differences in performance in the verbal and visual conditions. In addition differences in performance were found in response to the two event types and these differences varied across the two input modalities. These results suggest that the influencing factors that guide attention and foregrounding decisions in communicating events in drawing vary according to the input modality used. In the verbal condition order of mention was the strongest influencing factor, whilst in the visual condition foregrounding depended on the interaction of a number of perceptual factors. Results obtained from two of the participants with aphasia are discussed in the light of the above findings and reveal differences in performance, both in comparison with the controls and with one another.

The outcome of therapy in relation to his performance on formal and informal measures and his spontaneous speech production will be discussed. NS was a 49 year old gentleman who was 6 years post-onset when he was referred to the Newcastle Aphasia Clinic. His spontaneous speech was hesitant and characterised by incomplete, fragmented sentences and a reliance on sentences produced around the copular verb. Detailed assessment showed a significant impairment in verb retrieval and in the realisation of the predicate argument structure (PAS). Therapy aimed to improve NS’s sentence production by:- a) Improving his retrieval of verbs b) Increasing his awareness of the relationship between nouns and verbs and c) Improving his production of one, two and three argument structures. Therapy resulted in a significant improvement in his retrieval of treated verbs but no generalisation to untreated verbs. His sentence production more generally showed several changes:- improved realisation of the nouns within the PAS, reduced argument omission and a greater variety of argument structures within his connected speech. Therapy seemed to result in a greater awareness of the role of the verb within a sentence and a strategy for producing a PAS frame. This resulted in improved sentence production although verb retrieval difficulties were still evident. The implications of the results will be discussed.

However when investigating languages in which the valency of the verb is morphologically marked, most researchers have implicitly assumed that the thematic role assignment applied to the (sometimes ambiguous) morphological markers by children is appropriate (see Allen, 1996, among others). Thus children’s overgeneralizations have typically been classified into two categories: increased valency and decreased valency (Figueira, 1984; Allen, 1996). This classification fails to consider instances of unadult-like mapping between appropriate thematic role assignment and the inappropriate valencymarking morphological pattern associated with a verb which children have been shown to apply (see Allen, 1996 for examples in Inuktitut and Pye, 1988 & 1994 for Quiche). In light of this problem, we propose an alternative classification which includes an additional category -*Maintained Valency- which refers to instances when the thematic role assignment of the verb is maintained while the valency-marking morphological pattern associated with the verb is inappropriate. The consideration of these issues and the application of this new classification require the use of complementary research strategies when investigating the acquisition of AS. We illustrate our argument by presenting a study on ASA by French speaking children which relies on a range of methodological procedure (speech production, comprehension and grammaticality judgments, using real and nonce-verbs) and enable us to investigate children’s assignment of thematic roles to morphologically ambiguous constructions. The implications for theories on the acquisition of Argument Structure which have typically emphasized children’s reliance on semantic cues (Semantic Bootstrapping, Pinker, 1989) or syntactic cues (Gleitman, 1990), the re-interpretation of crosslinguistic findings and clinical populations are discussed.

Wester, R. Bastiaanse, E. Maas, D. den Ouden, L. Shapiro & D. Swinney We examined verb activation in Dutch matrix clauses during on-line sentence comprehension. The canonical word order in Dutch is SOV, but in matrix clauses the finite verb appears in the second position (SVO) (Koster, 1975). Thus, in Dutch matrix sentences the verb is not in its canonical position. Evidence for the relative complexity of V2 is found in neurolinguistic studies. For Dutch-speaking individuals with Broca's aphasia, finite verbs in second position are more difficult to produce than those in clause-final position (Bastiaanse & van Zonneveld, 1998; Bastiaanse et al., 2002a). The same holds for young children with and without language impairments (Bastiaanse et al., 2002b; De Jong, 1999). This supports the idea that the clause final position is the basic position of the verb, and that the word order in matrix clauses is more complex. It is now well established that in non-canonical structures, a noun that is displaced from its canonical position is reactivated on-line at that position (e.g. Love & Swinney 1996). It is unknown, however, whether displaced verbs will be similarly reactivated at their canonical positions. If they are, then a stronger case can be made for the possibility that listeners attempt to recover canonical word order on-line whenever they encounter a structure that is non-canonical. We studied the on-line activation pattern of verbs in Dutch matrix clauses by using the Cross-Modal Lexical Priming task: participants listened to sentences and at a specific point during each sentence, they had to make a lexical decision (word/nonword) to a probe that appeared on a screen. The word-probes that we used were verbs either related or unrelated to the displaced verb in the matrix clause. If the verb is activated at a particular point in a sentence, reaction times are expected to be faster for related than for unrelated probes (priming). We used sentences as in (1), embedded with two-argument verbs, and tested for priming at three probepoints: directly after the verb, 700 milliseconds downstream from the verb, and at the offset of the complementizer (the point where the parser unambiguously knows that there was a gap).

The results are presented in Table 1. Summarizing, we observed significantly faster reaction times to related probes relative to control probes (priming) both directly after the verb and 700 milliseconds downstream from the verb. Yet, we found no priming - no evidence for activation of the verb - at its 'canonical' position. Table 1. Mean reaction times (in msec) and standard deviations per probe-point and probe-type (subject-based analysis) control probe related probe difference probe-point 1 643 (77) 627 (74) 16* probe-point 2 645 (73) 628 (71) 17* probe-point 3 634 (77) 632 (83) 2 * p<.01 (one tailed, paired t-test) This pattern suggests that verbs behave differently from nouns; compared to the literature on gap-filling, verbs remain activated longer than nouns and they do not appear to be reactivated at the gap. In our experiment the third probe position occurred after the second argument. We suggest therefore that verbs remain active to 'find' their arguments to theta-mark them. Once thematic roles are discharged, we assume that activation for the verb will dissipate. In a second experiment we are taking a closer look at the temporal aspects of verb activation in Dutch matrix clauses. In this experiment we included a probe-point at the offset of the object head noun (the canonical position of the verb). Furthermore we lengthened the sentences and placed probe-point 2 at 1500 milliseconds downstream from the verb. We will present preliminary data at the conference.

Converging evidence suggests that these literacy difficulties stem from a language disorder which critically affects the phonological domain of language. However, recent data have demonstrated that the language deficit may go beyond phonological problems, affecting vocabulary and syntactic skills. For example, dyslexic children showed delayed acquisition of inflectional verb morphology at pre-school age (Scarborough, 1990). Older dyslexic children were found to be less sensitive to verb agreement morphology compared to normally developing children (Rispens & Koster, 2002). Neuroimaging studies (MEG/EEG), undertaken to find neurophysiological correlates of language deficits, suggest weaker and delayed neuronal activation for adult dyslexic readers when processing semantic information (Helenius et al., 1999, 2002). The present study investigates cortical activation in response to morphosyntactic information in adult dyslexics, using Event-Related brain Potentials (ERPs), focusing on the presence and properties of the P600 component which reflects syntactic repair/revision. Grammatical sentences and sentences containing subject-verb agreement violations were presented auditorily to Dutch speaking dyslexic and normal reading participants. Detection of agreement errors was unimpaired for the dyslexic subjects, as demonstrated by a grammaticality judgement task. The ERP data, however, showed differences between the two groups. The distribution of the P600 was more restricted to the right posterior brain region for the dyslexic subjects, in contrast with the control subjects who showed a significant P600 in the left, right and centroparietal region. In addition, the peak of the P600 component was delayed for the dyslexic subjects in comparison with the controls. In conclusion, the results demonstrate more restricted and delayed neuronal activation engaged in processing verb morphology information in dyslexic subjects. These data are in accordance with findings for semantic activation and underline the language basis of developmental dyslexia.

Verbs are the target of therapy as a) people with aphasia find accessing verbs difficult and b) verbs are central to sentence structure as they carry essential semantic and syntactic information. It is a multiple single subject study that uses an A1 B A2 design. In the first stage, subjects are given a series of repeated assessment over a 3month period. Repeated base-line measures are taken in order to gauge the stability of the language status. Measures include standardised assessments and continuous speech data, namely, conversational and monologic samples. A set of 100 verbs is used, 50 of which will be used in the therapy and 50 for control measures. Further control measures are included in the base-line phase where improvements are not predicted. The second stage is the treatment stage. Therapy is given in hourly sessions, twice a week using target verbs for four months. Subjects are required to practise at home for 20 minutes each day. Performance is logged for each session and records of home practice are kept. Therapy tasks are ranked from sentence completion, to naming from description to picture naming. A hierarchy of cues are used to aid error-free learning. The third stage is the follow-up assessment stage. Multiple testing is repeated at monthly intervals to reveal a) therapy effects and b) maintenance of therapy effects. Appropriate statistical tests are used to compare pre and post-therapy scores. Analyses of continuous speech data are made following Thompson et al’s procedures. Improvement in verb naming will demonstrate the effectiveness of therapy but an improvement in verb naming, sentence generation and grammatically well-formed continuous speech will demonstrate the key role of verbs in sentence production and the importance of treating verbs in aphasia therapy.

There were two groups of children participated in the experimental part of the study: one group of 4 SLI children and one control group of 12 normally developing children matched on chronological age. Two experiments were carried out; in the first one a picture description task was used while in the second one a picture-pointing task was used. The first experiment indicated that the SLI children used a limited verb lexicon comprising a considerable number of light verb constructions (LVCs) that were often used in a non-adult fashion. Despite the apparent differences between the performance of the SLI children and the control group on verb production, it is argued that the SLI children even when they produce non-adult LVCs follow the rules of the adult verb system in Greek. The second experiment indicated that there were no significant differences between the two groups in the comprehension of verbs. It is suggested that the SLI children’s problems with verb production can be attributed to difficulties in verb retrieval rather than to completely impaired lexical representations. The SLI children compensate for these difficulties by relying on a limited verb lexicon and exploiting the rules of LVCs formation in Greek.

First, can we capture important aspects of the semantic representations of words referring to objects and words referring to actions using the same tools? Second, does the distinction between nouns and verbs arise, in general, as a result of the underlying distinction between objects and actions, which is highly correlated to grammatical class? We will present modeling and experimental evidence compatible with a view in which the same tools can in fact be used to represent the meanings of both types of words, but crucially, in which the syntactic distinction (between nouns and verbs) and the semantic distinction (between objects and actions) are strictly separate.
