Bridging Inferences and Reference Management: Evidence from an Experimental Investigation in Catalan and Russian.

This article focuses on the choice of nominal forms in a language with articles (Catalan) in comparison to a language without articles (Russian). An experimental study (consisting of various naturalness judgment tasks) was run with speakers of these two languages which allowed to show that in bridging contexts native speakers' preferences vary when reference is made to one single individual or to two disjoint referents. In the former case, Catalan speakers chose (in)definite NPs depending on their accessibility to contextual information that guarantees a unique interpretation (or the lack of it) for the entity referred to. Russian speakers chose bare nominals as a default form. When reference is made to two disjoint referents (as encoded by the presence of an additional altre/drugoj "other" NP), speakers prefer an optimal combination of two indefinite NPs (i.e., un NP followed by un altre NP in Catalan; odin "some/a" NP followed by drugoj NP in Russian). This study shows how speakers of the two languages manage to combine grammatical knowledge (related to the meaning of the definite and the indefinite articles and altre in Catalan; and the meaning of bare nominals, odin and drugoj in Russian) with world knowledge activation and accessibility to discourse information.

On the distribution and interpretation of voice in Greek anticausatives.

This paper provides experimental evidence in support of the view that Greek does not have three productive morphological classes of anticausative verbs, but only two: the class of verbs that bear non-active voice morphology and the class of verbs that are morphologically active. Across two experiments, native Greek speakers are found to prefer for each anticausative verb either non-active or active voice morphological marking, in the presence or absence of explicit contextual information. It is also shown experimentally that native speakers prefer an interpretation that involves a specific cause for all anticausatives, especially when the existence of such a cause is favored by the contextual setting. Our empirical findings are consistent with the view that the Voice Phrase that is realized as non-active voice morphology in Greek anticausatives is expletive. From a theoretical perspective, we analyze the expletiveness of this Voice projection as the result of semantic redundancy: the Voice head of Greek anticausatives combines with a v head that encodes a redundant cause meaning component and is, therefore, interpreted merely as introducing an identity function.

Beat gestures help preschoolers recall and comprehend discourse information.

Although the positive effects of iconic gestures on word recall and comprehension by children have been clearly established, less is known about the benefits of beat gestures (rhythmic hand/arm movements produced together with prominent prosody). This study investigated (a) whether beat gestures combined with prosodic information help children recall contrastively focused words as well as information related to those words in a child-directed discourse (Experiment 1) and (b) whether the presence of beat gestures helps children comprehend a narrative discourse (Experiment 2). In Experiment 1, 51 4-year-olds were exposed to a total of three short stories with contrastive words presented in three conditions, namely with prominence in both speech and gesture, prominence in speech only, and nonprominent speech. Results of a recall task showed that (a) children remembered more words when exposed to prominence in both speech and gesture than in either of the other two conditions and that (b) children were more likely to remember information related to those words when the words were associated with beat gestures. In Experiment 2, 55 5- and 6-year-olds were presented with six narratives with target items either produced with prosodic prominence but no beat gestures or produced with both prosodic prominence and beat gestures. Results of a comprehension task demonstrated that stories told with beat gestures were comprehended better by children. Together, these results constitute evidence that beat gestures help preschoolers not only to recall discourse information but also to comprehend it.

The timing of head movements: The role of prosodic heads and edges.

This study examines the influence of the position of prosodic heads (accented syllables) and prosodic edges (prosodic word and intonational phrase boundaries) on the timing of head movements. Gesture movements and prosodic events tend to be temporally aligned in the discourse, the most prominent part of gestures typically being aligned with prosodically prominent syllables in speech. However, little is known about the impact of the position of intonational phrase boundaries on gesture-speech alignment patterns. Twenty-four Catalan speakers produced spontaneous (experiment 1) and semi-spontaneous head gestures with a confirmatory function (experiment 2), along with phrase-final focused words in different prosodic conditions (stress-initial, stress-medial, and stress-final). Results showed (a) that the scope of head movements is the associated focused prosodic word, (b) that the left edge of the focused prosodic word determines where the interval of gesture prominence starts, and (c) that the speech-anchoring site for the gesture peak (or apex) depends both on the location of the accented syllable and the distance to the upcoming intonational phrase boundary. These results demonstrate that prosodic heads and edges have an impact on the timing of head movements, and therefore that prosodic structure plays a central role in the timing of co-speech gestures.

Relating (Un)acceptability to Interpretation. Experimental Investigations on Negation.

Although contemporary linguistic studies routinely use unacceptable sentences to determine the boundary of what falls outside the scope of grammar, investigations far more rarely take into consideration the possible interpretations of such sentences, perhaps because these interpretations are commonly prejudged as irrelevant or unreliable across speakers. In this paper we provide the results of two experiments in which participants had to make parallel acceptability and interpretation judgments of sentences presenting various types of negative dependencies in Basque and in two varieties of Spanish (Castilian Spanish and Basque Country Spanish). Our results show that acceptable sentences are uniformly assigned a single negation reading in the two languages. However, while unacceptable sentences consistently convey single negation in Basque, they are interpreted at chance in both varieties of Spanish. These results confirm that judgment data that distinguish between acceptable and unacceptable negative utterances can inform us not only about an adult's grammar of his/her particular language but also about interesting cross-linguistic differences. We conclude that the acceptability and interpretation of (un)grammatical negative sentences can serve linguistic theory construction by helping to disentangle basic assumptions about the nature of various negative dependencies.

Vocative intonation preferences are sensitive to politeness factors.

Although intonation has been traditionally associated with the expression of attitudes and intentions on the part of the speaker, little is known about whether sociopragmatic factors, such as power or social distance, or situational ones, like physical distance or insistence, can constrain the use and felicity of pitch contours. This article investigates the felicity conditions underlying the choice of three vocative pitch contours in Central Catalan by means of two experiments, namely a production experiment based on the Discourse Completion Task (320 vocative contours produced by 20 speakers), and an acceptability judgment task in which 72 listeners were asked to rate the appropriateness match between a set of vocative contours and a previous discourse context (3,456 responses). The results from the two experiments show that both situational and social politeness factors govern the choice of vocative intonation. Finally, the results are discussed in line with the traditional classification of politeness strategies defined by Brown and Levinson, in the sense that the three intonation contours can be linked to negative, positive, and bald on-record politeness strategies.

Specific neural traces for intonational discourse categories as revealed by human-evoked potentials.

The neural representation of segmental and tonal phonological distinctions has been shown by means of the MMN ERP, yet this is not the case for intonational discourse contrasts. In Catalan, a rising-falling intonational sequence can be perceived as a statement or as a counterexpectational question, depending exclusively on the size of the pitch range interval of the rising movement. We tested here, using the MMN, whether such categorical distinctions elicited distinct neurophysiological patterns of activity, supporting their specific neural representation. From a behavioral identification experiment, we set the boundary between the two categories and defined four stimuli across the continuum. Although the physical distance between each pair of stimuli was kept constant, the central pair represented an across-category contrast, whereas the other pairs represented within-category contrasts. These four auditory stimuli were contrasted by pairs in three different oddball blocks. The mean amplitude of the MMN was larger for the across-category contrast, suggesting that intonational contrasts in the target language can be encoded automatically in the auditory cortex. These results are in line with recent findings in other fields of linguistics, showing that, when a boundary between categories is crossed, the MMN response is not just larger but rather includes a separate subcomponent.
