From the perspective of pragmatic tolerance, this study investigates L1-Mandarin Chinese L2-English speakers’ derivation of scalar implicatures, with a focus on L2 speakers’ pragmatic tolerance when facing a violation of pragmatic principle. Results from a graded judgment task show that L2 speakers have native-like pragmatic tolerance of underinformative sentences. More importantly, this pragmatic tolerance does not differ between L2 speakers’ native and second languages. This study aims to provide insight for experimental design in semantics-pragmatics research, as well as for second language acquisition of scalar implicatures.

This study explores how L1 and L2 Chinese speakers use world knowledge and classifier information to predict fine-grained referent features. In a visual-world-paradigm eye-tracking experiment, participants were presented with two visual objects that were denoted by the same noun in Chinese but matched different shape classifiers. Meanwhile, they heard sentences containing world knowledge triggering context and classifiers. The effect of world knowledge has been differentiated from word-level associations. Native speakers generated anticipations about the shape/state features of the referents at an early processing stage and quickly integrated linguistic information with world knowledge upon hearing the classifiers. In contrast, L2 speakers show delayed, reduced anticipation based on world knowledge and minimal use of classifier cues. The findings reveal different cue-weighting strategies in L1 and L2 processing. Specifically, L2 speakers whose first languages lack obligatory classifiers do not employ classifier cues in a timely manner, even though the semantic meanings of shape classifiers are accessible to them. No evidence supports over-reliance on world knowledge in L2 processing. This study contributes to the understanding of L2 real-time processing, particularly in L2 speakers’ utility of linguistic and non-linguistic information in anticipating fine-grained referent features.

Linguistic communication requires interlocutors to consider differences in each other’s knowledge (perspective-taking). However, perspective-taking might either be spontaneous or strategic. We monitored listeners’ eye movements in a referential communication task. A virtual speaker gave temporally ambiguous instructions with scalar adjectives (“big” in “big cubic block”). Scalar adjectives assume a contrasting object (a small cubic block). We manipulated whether the contrasting object (a small triangle) for a competitor object (a big triangle) was in common ground (visible to both speaker and listener) or was occluded so it was in the listener’s privileged ground, in which case perspective-taking would allow earlier reference-resolution. We used a complex visual context with multiple objects, making strategic perspective-taking unlikely when all objects are in the listener’s referential domain. A turn-taking, puzzle-solving task manipulated whether participants could anticipate a more restricted referential domain. Pieces were either confined to a small area (requiring fine-grained coordination) or distributed across spatially distinct regions (requiring only coarse-grained coordination). Results strongly supported spontaneous perspective-taking: Although comprehension was less time-locked in the coarse-grained condition, participants in both conditions used perspective information to identify the target referent earlier when the competitor contrast was in privileged ground, even when participants believed instructions were computer-generated.

Events are not isolated but rather linked to one another in various dimensions. In language processing, various sources of information—including real-world knowledge, (representations of) current linguistic input and non-linguistic visual context—help establish causal connections between events. In this review, we discuss causal inference in relation to events and event knowledge as one aspect of world knowledge, and their representations in language comprehension. To evaluate the mechanism and time course of causal inference, we gather insights from studies on (1) implicit causality/consequentiality as a specific form of causal inference regarding the protagonists of cause/consequence events, and (2) the processing of causal relations. We highlight the importance of methodology in measuring causal inference, compare the results from different research methods, and emphasize the contribution of the visual-world paradigm to achieve a better understanding of causal inference. We recommend that further investigations of causal inference consider temporally sensitive measures and more detailed contexts.

The visual world paradigm (VWP) assesses real-time language processing by tracking and measuring eye movements in visual contexts. Linking hypotheses, such as the coordinated interplay account and the goal-based linking hypothesis, establish the link between eye movements and the cognitive processes of language comprehension. Time sensitivity is characteristic of the data generated by this paradigm. Analytical methods include the analysis of fixation proportions within time windows, divergence point analysis and growth-curve analysis, etc. Studies using the VWP provide important evidence for speech and lexical recognition, syntactic parsing, semantic integration, and the processing of discourse and pragmatic information.

Perspective-taking, which is important for communication and social activities, can be cultivated through joint actions, including musical activities in children. We examined how rhythmic activities requiring coordination affect perspective-taking in a referential communication task with 100 Chinese 4- to 6-year-old children. In Study 1, 5- to 6-year-old children played an instrument with a virtual partner in one of three coordination conditions: synchrony, asynchrony, and antiphase synchrony. Eye movements were then monitored with the partner giving instructions to identify a shape referent which included a pre-nominal scalar adjective (e.g., big cubic block). When the target contrast (a small cubic block) was in the shared ground and a competitor contrast was occluded for the partner, participants who used perspective differences could, in principle, identify the intended referent before the shape was named. We hypothesized that asynchronous and antiphase synchronous musical activities, which require self-other distinction, might have stronger effects on perspective-taking than synchronous activity. Children in the asynchrony and antiphase synchrony conditions, but not the synchrony condition, showed anticipatory looks at the target, demonstrating real-time use of the partner's perspective. Study 2 was conducted to determine if asynchrony and antiphase asynchrony resulted in perspective-taking that otherwise would not have been observed, or if synchronous coordination inhibited perspective-taking that would otherwise have occurred. We found no evidence for online perspective-taking in 4- to 6-year-old children without music manipulation. Therefore, playing instruments asynchronously or in alternation, but not synchronously, increases perspective-taking in children of this age, likely by training self-other distinction and control.

We evaluated the effectiveness of new indices of text comprehension in measuring relative text difficulty. Specifically, we examined the efficacy of automated indices produced by the web-based computational tool Coh-Metrix. In an analysis of 60 instructional science texts, we divided texts into groups that were considered to be more or less difficult to comprehend. The defining criteria were based on Coh-Metrix indices that measure independent factors underlying text coherence: referential overlap and vocabulary accessibility. In order to validate the text difficulty groups, participants read and recalled two “difficult” and two “easy” texts that were similar in topic and length. Easier texts facilitated faster reading times and better recall compared to difficult texts. We discuss the implications of these results in the context of theoretically motivated techniques for improving textbook selection. 

Interpreting subjectivity in causal relations takes effort: Subjective, claim-argument relations are read slower than objective, cause-consequence relations. In an eye-tracking-while-reading experiment, we investigated whether connectives and stance markers can play a facilitative role. Sixty-five Chinese participants read sentences expressing a subjective causal relation, systematically varied in the use of stance markers (no, attitudinal, epistemic) in the first clause and connectives (neutral suoyi “so”, subjective kejian “so”) in the second clause. Results showed that processing subjectivity proceeds highly incrementally: The interplay of the subjectivity markers is visible as the sentence unfolds. Subjective connectives increased reading times, irrespective of the type of stance marker being used. Stance markers did, however, facilitate the processing of modal verbs in subjective relations. We conclude that processing subjectivity involves evaluating how the argument supports the claim and that connectives, modal verbs, and stance markers function as processing instructions that help readers achieve this evaluation.

Collocation analysis can be used to extract meaningful linguistic information from large-scale corpus data. This paper reviews the methodological issues one may encounter when performing collocation analysis for discourse studies on Chinese. We propose four crucial aspects to consider in such analyses: (i) the definition of collocates according to various parameters; (ii) the choice of analysis and association measures; (iii) the definition of the search span; and (iv) the selection of corpora for analysis. To illustrate how these aspects can be addressed when applying a Chinese collocation analysis, we conducted a case study of two Chinese causal connectives: yushi ‘that is why’ and yin’er ‘as a result’. The distinctive collocation analysis shows how these two connectives differ in volitionality, an important dimension of discourse relations. The study also demonstrates that collocation analysis, as an explorative approach based on large-scale data, can provide valuable converging evidence for corpus-based studies that have been conducted with laborious manual analysis on limited datasets.

We investigated whether fine-grained coordination in a screen-based puzzle task with a (virtual) partner would influence on-line perspective-taking. Participants played a screen-based puzzle game with a computer player. In the high-coordination condition, the player presented participants with puzzle pieces that could be placed near their partner’s last piece. In the low-coordination condition, pieces could only be placed further away from their partner’s last piece. Participant’s eye movements were then measured in a referential communication task, with the partner giving the instructions, and whether possible competitor referents were in shared or privileged ground. The results demonstrate clear effects of ground and coordination. Participants in both coordination groups were sensitive to the perspective of the interlocutor. In addition, participants in the high-level coordination condition were more sensitive to statistical regularities in the input and their comprehension was more time-locked to the utterance of the speaker.

This study explores how subjectivity is expressed in coherence relations, by means of a distinctive collocational analysis on two Chinese causal connectives: the specific subjective kejian ‘so’, used in subjective argument-claim relations, and the underspecified suoyi ‘so’, which can be used in both subjective argument-claim and objective cause-consequence relations. On the basis of both Horn’s pragmatic Relation and Quality principles and the Uniform Information Density Theory, we hypothesized that the presence of other linguistic elements expressing subjectivity in a discourse segment should be related to the degree of subjectivity encoded by the connective. In line with this hypothesis, the association scores showed that suoyi is more frequently combined with perspective markers expressing epistemic stance: cognition verbs and modal verbs. Kejian, which already expresses epistemic stance, co-occurred more often with perspective markers related to attitudinal stance, such as markers of expectedness and importance. The paper also pays attention to similarities and differences in collocation patterns across contexts and genres.

Causal relations can be presented as subjective, involving someone's reasoning, or objective, depicting a real- world cause-consequence relation. Subjective relations require longer processing times than objective relations. We hypothesize that the extra time is due to the involvement of a Subject of Consciousness (SoC) in the mental representation of subjective information. To test this hypothesis, we conducted a Visual World Paradigm eye- tracking experiment on Dutch and Chinese connectives that differ in the degree of subjectivity they encode. In both languages, subjective connectives triggered an immediate increased attention to the SoC, compared to objective connectives. Only when the subjectivity information was not expressed by the connective, modal verbs presented later in the sentence induced an increase in looks at the SoC. This focus on the SoC due to the linguistic cues can be explained as the tracking of the information source in the situation models, which continues throughout the sentence.

Language users need to interpret others’ subjective opinions in communication. In causal relations, subjectivity is defined as the involvement of a speaker who is responsible for the causal reasoning. Subjectivity can be expressed by various linguistic cues such as perspective markers (e.g. I think, it is said) and modal verbs (e.g. may, must). Some connectives encode subjectivity as well – the Chinese connective kejian ‘so/therefore’ and the Dutch connective dus ‘so’ indicate that a causal relation is based on the subjective reasoning of the speaker. These linguistic cues function as instructions for comprehenders in on-line language processing. This dissertation explores the use of linguistic markers expressing subjectivity in discourse and how these markers influence the representation and processing of discourse. Three different methods were applied to Mandarin Chinese: a collocational analysis, an on- line reading study and a visual world paradigm eye-tracking study. The results show that linguistic cues such as perspective markers and modal verbs are used in combination with connectives to express subjectivity in causal relations. In on-line reading, these linguistic cues function as processing instructions to readers – helping them track the source of information and interpret subjectivity. Moreover, this process is highly incremental. An eye-tracking study using the visual world paradigm provided evidence about how subjectivity influences processing: the processing of subjectivity involves activating the source of information in the mental representation of the linguistic input. Combining these three methods has proved to be a fruitful way of gaining more insight into the phenomenon of subjectivity.
