The effects of discourse coherence on the persistence of sentence structures.

We studied the role of discourse coherence relations on structure formulation in sentence production by examining whether a connective, an essential signal of coherence relations, modulates the tendency for speakers to reuse sentence structures (i.e., structural priming). We further examined three possible modulating factors: the type of connectives (additive vs. adversative connective), event similarity (similar event vs. different event), and topic cohesion (with or without available anaphoric antecedent). In four structural priming experiments, native Dutch participants were asked to read either a Dutch double object sentence or a prepositional object sentence and describe pictures that depicted ditransitive events. Critically, the prime and the target either were linked by a connective (en "and" or maar "but") or were not linked. The verb overlap between the prime and the target was also manipulated. In Experiment 1, the presence of en facilitated structural priming, but only when the verbs were different. In Experiment 2, maar reduced structural priming when the verbs were repeated. Experiment 3 replicated the findings of Experiments 1 and 2 in a within-subjects design. In Experiment 4, there was no referential link between the sentences. Now there was no connective effect on structural priming. Taken together, we demonstrated that the insertion of a connective influences syntactic persistence. The connective effects vary across semantic properties of the connectives, event similarity, and referential continuity, suggesting that the production of sentence structure is modulated by speakers' prediction about listeners' inference of coherence relations between consecutive utterances.

Two sides of the same coin? Comparing structural priming between production and comprehension in choice data and in reaction times.

Although structural priming seems to rely on the same mechanisms in production and comprehension, effects are not always consistent between modalities. Methodological differences often result in different data types, namely choice data in production and reaction time data in comprehension. In a structural priming experiment with English ditransitives, we collected choice data and reaction time data in both modalities. The choice data showed priming of the DO and PO dative. The reaction times revealed priming of the PO dative. In production, PO targets were chosen faster after a PO prime than after a baseline prime. In comprehension, DO targets were read slower after a PO prime than after a baseline prime. This result can be explained from competition between alternatives during structure selection. Priming leads to facilitation of the primed structure or inhibition of the opposite structure depending on the relative frequency of structures, which may differ across modalities.

Envisioning multilingualism in source-based writing in L1, L2, and L3: The relation between source use and text quality.

In this article, we report on a study that investigates how master's students consult external sources for reading-to-write integrated tasks in their L1 (Dutch), L2 (English), and L3 (French). Two hundred and eighty master's students in professional communication wrote synthesis texts based on three external sources, including a report, a web text, and a newspaper article in their L1 (Dutch), and in L2 (English), or L3 (French) at two moments of measurement, which were separated by an interval of 6 months. Their source use activities during the writing process were registered using Inputlog - a keylogging program. Inputlog enabled us to determine the amount of time the writers spent composing their main texts and consulting the sources (when the source consultation activities took place during the writing process, which sources were consulted most frequently, and how frequently the writers transitioned between the various sources). Final text quality was assessed holistically using pairwise comparisons (D-pac, now Comproved). Confirmatory factor analysis indicated three components that could describe source use processes in L1, L2, and L3 writing: (a) initial reading time, (b) source interaction, and (c) variance of source use throughout the writing process. Within-subject comparisons revealed that there were no improvements in the students' text quality in L1, L2, and L3 over an academic year. Structural equation modeling indicated that the source use approach, particularly source interaction, is related to text quality, but only in L1 and L3. We provide further explanations for this variation based on language proficiency, temporal distribution of writing process, and individual differences.

On the limits of shared syntactic representations: When word order variation blocks priming between an artificial language and Dutch.

Several studies used artificial language (AL) learning paradigms to investigate structural priming between languages in early phases of learning. The presence of such priming would indicate that these languages share syntactic representations. Muylle et al. (2020a) found similar priming of transitives and ditransitives between Dutch (SVO order) and an AL with either SVO or SOV order. However, it is unclear whether such sharing would occur if the AL allows both the same and different word order as the L1. Indeed, the presence of a (easy to share) similar structure might block (i.e., impede) sharing of a less similar structure. Here, we report 2 experiments that each tested 48 Dutch native speakers on an AL that allowed both SVO and SOV order in transitive and ditransitive sentences. We assessed both within-AL and AL-Dutch priming. We predicted (a) priming of both structure and word order within the AL, and (b) weaker AL-Dutch priming from SOV versus SVO sentences due to the presence of SVO sentences in the AL. Indeed, cross-linguistic priming was significantly weaker in SOV versus SVO conditions, but the blocking hypothesis was only supported by the transitive results. Unexpectedly, in the absence of a condition with verb overlap between prime and target sentences, no priming was found in AL and Dutch target conditions without verb overlap (Experiment 1), but priming emerged when a verb overlap condition was added (Experiment 2). This finding suggests that lexical repetition across sentences is crucial to establish abstract syntactic representations during early L2 acquisition.

The role of explicit memory in syntactic persistence: Effects of lexical cueing and load on sentence memory and sentence production.

Speakers' memory of sentence structure can persist and modulate the syntactic choices of subsequent utterances (i.e., structural priming). Much research on structural priming posited a multifactorial account by which an implicit learning process and a process related to explicit memory jointly contribute to the priming effect. Here, we tested two predictions from that account: (1) that lexical repetition facilitates the retrieval of sentence structures from memory; (2) that priming is partly driven by a short-term explicit memory mechanism with limited resources. In two pairs of structural priming and sentence structure memory experiments, we examined the effects of structural priming and its modulation by lexical repetition as a function of cognitive load in native Dutch speakers. Cognitive load was manipulated by interspersing the prime and target trials with easy or difficult mathematical problems. Lexical repetition boosted both structural priming (Experiments 1a-2a) and memory for sentence structure (Experiments 1b-2b) and did so with a comparable magnitude. In Experiment 1, there were no load effects, but in Experiment 2, with a stronger manipulation of load, both the priming and memory effects were reduced with a larger cognitive load. The findings support an explicit memory mechanism in structural priming that is cue-dependent and attention-demanding, consistent with a multifactorial account of structural priming.

English norming data for 423 short animated action movie clips.

We present a set of 423 animated action movie clips of 3 s, that we expect to be useful for a variety of experimental paradigms in which sentences are elicited. The clips either depict an action involving only an agent (intransitive action, e.g., a policeman that is sleeping), an action involving an agent and a patient (transitive action, e.g., a policeman shooting a pirate), or an action involving an agent, an object, and a beneficiary (ditransitive action, e.g., a policeman showing a hat to a pirate). In order to verify that the movie clips (when presented with a verb) indeed elicit intransitive, transitive, or ditransitive sentences, we conducted a written norming study with native speakers of American English. We asked 203 participants to describe the clips with a sentence using a given verb. The movie clips elicited valid responses in 90% of the cases. Moreover, there was an active response bias for the transitives, and a prepositional object dative (PO-dative) response bias for the ditransitives. This bias differed between verbs in the ditransitives. A list is provided with all clips and the proportion of each response type for each clip. The clips are stored as MP4-files and can be freely downloaded.

Syntactic levels, lexicalism, and ellipsis: The jury is still out.

Structural priming data are sometimes compatible with several theoretical views, as shown here for three key theoretical claims. One reason is that prime sentences affect multiple representational levels driving syntactic choice. Additionally, priming is affected by further cognitive functions (e.g., memory). We therefore see priming as a useful tool for the investigation of linguistic representation but not the only tool.

From language-specific to shared syntactic representations: the influence of second language proficiency on syntactic sharing in bilinguals.

Studies on cross-linguistic syntactic priming suggest that bilinguals can share syntactic representations across languages (e.g., Hartsuiker, Pickering, & Veltkamp, 2004). But how are these representations established in late learners of a second language? Specifically, are representations of syntactic structures in a second language (L2) immediately collapsed with similar structures of the first language (L1), or are they initially represented separately? In order to investigate this, we primed the use of English genitives with Dutch (Experiment 1) and English (Experiment 2) genitives (e.g., het hemd van de jongen/the shirt of the boy vs. de jongen zijn hemd/the boy's shirt) in late Dutch-English bilinguals with varying levels of proficiency in English (their L2). The head nouns of prime and target constructions either had the same meaning (hemd/shirt - shirt) or a different meaning (duim/thumb - shirt), in order to test whether the use of both genitives was generalized across nouns. Experiment 1 found stronger between-language priming for more than less proficient bilinguals in both conditions, thus suggesting a shift from language-specific to shared syntactic representations. Experiment 2 suggests that these early, language-specific syntactic representations might be item-specific: Less proficient bilinguals showed much weaker priming when the heads of prime and target constructions had different meanings than when they were repeated.

Does verb bias modulate syntactic priming?

In a corpus analysis of spontaneous speech Jaeger and Snider (2007) found that the strength of structural priming is correlated with verb alternation bias. This finding is consistent with an implicit learning account of syntactic priming: because the implicit learning model implemented by Chang (2002), Chang, Dell, and Bock (2006), and Chang, Dell, Bock, and Griffin (2000) uses probabilistic information about different verb-structure combinations to predict the form of sentences, it predicts that primes exert stronger priming when they are less expected, given the syntactic preference of their main verb. We tested this claim experimentally by comparing the strength of double-object dative priming (DO) and prepositional object dative priming (PO) between dative verbs with differing syntactic preferences in a syntactic priming experiment. The syntactic preferences of the prime and target verbs were first measured in a picture description experiment. Consistent with an implicit learning account, the results showed a verb-specific effect of inverse preference: the strength of DO-priming was modulated by the alternation bias of the dative verbs that were used in the primes.

Persistence of emphasis in language production: a cross-linguistic approach.

This study investigates the way in which speakers determine which aspects of an utterance to emphasize and how this affects the form of utterances. To do this, we ask whether the binding between emphasis and thematic roles persists between utterances. In one within-language (Dutch-Dutch) and three cross-linguistic (Dutch-English) structural priming experiments, we measured persistence effects for four different Dutch transitives (actives, PP-initial passives, PP-medial passives, and PP-final passives). Whereas English allows only one passive (PP-final passive), Dutch allows three different variants with the same functional assignment, but different constituent structures. Additionally, the degree of emphasis on the agent differs significantly between the PP-initial passive and the other passives (Experiment 1). Experiment 2 showed persistence of actives, PP-medial, and PP-final passives in Dutch, but no priming between passives with different constituent structures. Experiments 3 and 4, however, showed that both PP-medial and PP-final passives prime the use of English passives. Experiment 5 confirmed that the emphasis on thematic roles persists: the proportion of passives in the PP-initial passive condition fell midway between the proportions produced in the active and PP-medial passive condition.

Shared syntactic representations in bilinguals: Evidence for the role of word-order repetition.

Studies on syntactic priming strongly suggest that bilinguals can store a single integrated representation of constructions that are similar in both languages (e.g., Spanish and English passives; R. J. Hartsuiker, M. J. Pickering, & E. Veltkamp, 2004). However, they may store 2 separate representations of constructions that involve different word orders (e.g., German and English passives; H. Loebell & K. Bock, 2003). In 5 experiments, the authors investigated within--and between--languages priming of Dutch, English, and German relative clauses. The authors found priming within Dutch (Experiment 1) and within English as a 2nd language (Experiments 2 and 4). An important finding is that priming occurred from Dutch to German (Experiment 5), which both have verb-final relative clauses; but it did not occur between Dutch and English (Experiments 3 and 4), which differ in relative-clause word order. The results suggest that word-order repetition is needed for the construction of integrated syntactic representations.
