Processing Difficulty

Interference has been identified as a cause of processing difficulty in linguistic dependencies, such as the subject-verb relation (Van Dyke and Lewis, 2003). However, while mounting evidence implicates retrieval interference in sentence processing, the nature of the retrieval cues involved - and thus the source of difficulty - remains largely unexplored. Three experiments used self-paced reading and eye-tracking to examine the ways in which the retrieval cues provided at a verb characterize subjects. Syntactic theory has identified a number of properties correlated with subjecthood, both phrase-structural and thematic. Findings replicate and extend previous findings of interference at a verb from additional subjects, but indicate that retrieval outcomes are relativized to the syntactic domain in which the retrieval occurs. One, the cues distinguish between thematic subjects in verbal and nominal domains. Two, within the verbal domain, retrieval is sensitive to abstract syntactic properties associated with subjects and their clauses. We argue that the processing at a verb requires cue-driven retrieval, and that the retrieval cues utilize abstract grammatical properties which may reflect parser expectations.

Recent Extension

Among theories of human language comprehension, cue-based memory retrieval has proven to be a useful framework for understanding when and how processing difficulty arises in the resolution of long-distance dependencies. Most previous work in this area has assumed that very general retrieval cues like [+subject] or [+singular] do the work of identifying (and sometimes misidentifying) a retrieval target in order to establish a dependency between words. However, recent work suggests that general, hand-picked retrieval cues like these may not be enough to explain illusions of plausibility (Cunnings & Sturt, 2018), which can arise in sentences like The letter next to the porcelain plate shattered. Capturing such retrieval interference effects requires lexically specific features and retrieval cues, but hand-picking the features is hard to do in a principled way and greatly increases modeler degrees of freedom. To remedy this, we use word embeddings, a well-established method for creating distributed feature representations, for lexical features and retrieval cues. We show that the similarity between the features and the cues (a measure of plausibility) predicts total reading times in Cunnings and Sturt’s eye-tracking data. The features can easily be plugged into existing parsing models (including cue-based retrieval and self-organized parsing), putting very different models on more equal footing and facilitating future quantitative comparisons. In addition to this methodological contribution, our results suggest that, contrary to Cunnings and Sturts’ original conclusions, focused words might be more prominent in memory, making them less susceptible to interference, as predicted by a recent extension to ACT-R (Engelmann, Jäger, & Vasishth, 2019).

Retrieval Interference

Several comprehension studies have found evidence for number attraction effects: Processing a number-inflected verb is harder when a NP with the same number intervenes between the subject and verb (Pearlmutter et al., 1999; Wagers et al., 2009). This predicts that "was" in Example 1 should be harder when the verb is preceded by a plural ("customers" or "directors") than a singular NP. In contrast, similarity-based interference (Dyke & Lewis, 2003; Vasishth & Lewis 2005) predicts retrieval interference when a verb needs to be integrated with its dependents. The retrieval of a dependent should be more difficult when it shares retrieval cues (e.g., number) with another phrase. This predicts longer reading times at "was" with singular interfering NPs (customer or director). 1. The secretary | who argued with | the customer(s) of the director(s) | was on | the train | to the meeting. An eye-tracking experiment showed a number interference effect from the local NP ("director") in first fixation for the train and from the second NP ("customer") in total times for the same region. There was no number attraction effect. One possibility is that we did not find evidence for number attraction because the number attractor was syntactically deeply embedded in a relative clause. To test number attraction from nouns not in a relative clause, the intervening attractor ("farmers") was in a PP in Experiment 2. We also tested whether attraction effects might be part of checking processes after initial structure building. If so, these effects should be strong during reanalysis. Thus, we compared structurally ambiguous (2, without comma) and unambiguous sentences (with comma). The verb "has" not only resolves the ambiguity, it also agrees with "cousin". Thus, when the verb is preceded by a plural number attractor ("farmers"), reanalysis should be harder according to the number attraction account. 2. After Virginia answered(,) the cousin of the farmer(s) | has to | think it | all over again. Ambiguous sentences took longer to read than unambiguous sentences. More importantly, although there was no attraction or interference effect for unambiguous sentences, regression-path times for "has to" in the ambiguous sentences were longer when there was a plural than singular attractor. This suggests that number attraction affects comprehension as part of a checking process. We will discuss the implications of both experiments for number attraction and similarity-based interference.

Default Assumption

A long-standing debate in the sentence processing literature concerns the time course of syntactic and semantic information in online sentence comprehension. The default assumption in cue-based models of parsing is that syntactic and semantic retrieval cues simultaneously guide dependency resolution. When retrieval cues match multiple items in memory, this leads to similarity-based interference. Both semantic and syntactic interferencehave been shown to occur in English. However, the relative timing of syntactic vs. semantic interference remains unclear. In this first-ever cross-linguistic investigation of the time course of syntactic vs. semantic interference, the data from two eye-tracking reading experiments (English and German) suggest that the two types of interference can in principle arise simultaneously during retrieval. However, the data also indicate that semantic cues may be evaluated with a small timing lag in German compared to English. This suggests that there may be cross-linguistic variation in how syntactic and semantic cues are used to resolve linguistic dependencies in real-time.

Syntactic Properties

This chapter examines expressions of commands (imperatives) in Wolaitta and the ways in which the imperative is distinguished from statements and questions. Although each sentence type is formally distinct, imperatives and questions share a number of morpho-syntactic properties. Similar to declarative and interrogative sentences, imperatives in Wolaitta involve verbal grammatical categories such as the distinction of person, number, and gender of the subject as well as negative and positive polarity. In contrast to previous studies, the present contribution establishes the function of a set of morphemes based on -árk and -érk to be the expression of plea or appeal to an addressee rather than politeness when issuing a command. Instead, politeness in commands is expressed by using plural (pro)nominal and verbal elements. The imperative in Wolaitta is a robust construction which is also used in formulaic speeches such as leave-taking as well as in blessing, curses, and advice.

AbstractThis paper discusses a series of morpho-syntactic properties of Romance languages that have the functional projection vP as its locus, showing a continuum that goes from strongly configurational Romance languages to partially configurational Romance languages. It is argued that v-related phenomena like Differential Object Marking (DOM), participial agreement, oblique clitics, auxiliary selection, and others align in a systematic way when it comes to inflectional properties that involve Case-agreement properties. In order to account for the facts, I argue for a micro-parametric approach whereby v can be associated with an additional projection subject to variation (cf. D’Alessandro, Merging Probes. A typology of person splits and person-driven differential object marking. Ms., University of Leiden, 2012; Microvariation and syntactic theory. What dialects tell us about language. Invited talk given at the workshop The Syntactic Variation of Catalan and Spanish Dialects, Universitat Autònoma de Barcelona, Barcelona, June 26–28, 2013; Ordóñez, Cartography of postverbal subjects in Spanish and Catalan.

Amsterdam: John Benjamins, 2007). I label such projection “X,” arguing that its feature content and position varies across Romance. More generally, the present paper aims at contributing to our understanding of parametric variation of closely related languages by exploiting the intuition, embodied in the so-called Borer-Chomsky Conjecture, that linguistic variation resides in the functional inventory of the lexicon.

In this study, we examined eye movements and comprehension in sentences containing a relative clause. To date, few studies have focused on syntactic processing in dyslexia and so one goal of the study is to contribute to this gap in the experimental literature. A second goal is to contribute to theoretical psycholinguistic debate concerning the cause and the location of the processing difficulty associated with object-relative clauses. We compared dyslexic readers (n = 50) to a group of non-dyslexic controls (n = 50). We also assessed two key individual differences variables (working memory and verbal intelligence), which have been theorised to impact reading times and comprehension of subject- and object-relative clauses. The results showed that dyslexics and controls had similar comprehension accuracy. However, reading times showed participants with dyslexia spent significantly longer reading the sentences compared to controls (i.e., a main effect of dyslexia). In general, sentence type did not interact with dyslexia status. With respect to individual differences and the theoretical debate, we found that processing difficulty between the subject and object relatives was no longer significant when individual differences in working memory were controlled. Thus, our findings support theories, which assume that working memory demands are responsible for the processing difficulty incurred by (1) individuals with dyslexia and (2) object-relative clauses as compared to subject relative clauses.

ABSTRACTIn this paper we report on a visual world eye-tracking experiment that investigated the differing abilities of adults and children to use referential scene information during reanalysis to overcome lexical biases during sentence processing. The results showed that adults incorporated aspects of the referential scene into their parse as soon as it became apparent that a test sentence was syntactically ambiguous, suggesting they considered the two alternative analyses in parallel. In contrast, the children appeared not to reanalyze their initial analysis, even over shorter distances than have been investigated in prior research. We argue that this reflects the children's over-reliance on bottom-up, lexical cues to interpretation. The implications for the development of parsing routines are discussed.

In recent years, the number of studies in tourism using the eye tracking technique has increased and started generating valuable information for both academics and the industry. However, there is a gap in the literature concerning systematic reviews focused on recent articles and their findings. Thus, the aim of this study is to close this gap by systematically analysing 70 research papers tackling the subject of eye tracking in tourism and published in highly ranked tourism journals. The study identifies the most popular topics and trends for eye tracking research, as well as the most used types of visual stimuli, such as exhibitions, restaurant menus, promotional pictures or websites. The study also details on measurements specific for the analysis of eye tracking data, including fixations, saccades and heat maps. Results are emphasized along with their theoretical and practical implications. In addition, we highlight the lack of the use of dynamic stimuli in the existing literature and suggest further research directions using the eye tracking technique.

Partial Success

We present a comprehensive empirical evaluation of the ACT-R-based model of sentence processing developed by Lewis & Vasishth (2005) (LV05). The predictions of the model are compared with the results of a recent meta-analysis of published reading studies on retrieval interference in reflexive-/reciprocal-antecedent and subject-verb dependencies (Jäger, Engelmann, & Vasishth, 2017). The comparison shows that the model has only partial success in explaining the data; and we propose that its prediction space is restricted by oversimplifying assumptions. We then implement a revised model that takes into account differences between individual experimental designs in terms of the prominence of the target and the distractor in memory and context-dependent cue-feature associations. The predictions of the original and the revised model are quantitatively compared with the results of the meta-analysis. Our simulations show that, compared to the original LV05 model, the revised model accounts for the data better. The results suggest that effects of prominence and variable cue-feature associations need to be considered in the interpretation of existing empirical results and in the design and planning of future experiments. With regard to retrieval interference in sentence processing and to the broader field of psycholinguistic studies, we conclude that well-specified models in tandem with high-powered experiments are needed in order to uncover the underlying cognitive processes.
