The effects of phrase-length order and scrambling in the processing of visually presented Japanese sentences

The present study investigated the effects of phrase length and scrambling in the processing of Japanese sentences. Reading times of short phrases, long phrases, verbs, and whole sentences, measured by the method of self-paced reading, did not differ in terms of phrase-length order and scrambling. In addition, four types of sentences constructed on the basis of phrase-length order and scrambling did not affect duration times of correctness decision-making for sentences. However, error rates differed between canonical and scrambled sentences regardless of phrase-length order. This result implies that scrambled sentences were harder to judge as correct sentences than canonical sentences. Thus, scrambling affects the appropriate integration of information, whereas phrase-length order is simply an indication of preference and not of cognitive processing. To explain the present result, the authors propose the configurational structure without movement, which predicts no difference in speed between the processing of canonical and scrambled sentences, apart from error rates.     

Plausibility and subcategorization preference in children's processing of temporarily ambiguous sentences: Evidence from self-paced reading

Three self-paced reading experiments investigated children's processing of temporarily ambiguous sentences. Across the three experiments, subcategorization preference of a verb in a subordinate clause and the semantic plausibility of the misanalysis were manipulated. Reading times in the temporarily ambiguous region and following syntactic disambiguation indicated that children in the age range tested (8 years, 11 months to 12 years, 11 months) routinely misanalyse sentences of the type tested, and their tendency to misanalyse the sentences does not depend on the subcategorization preferences of the initial verb. Additional correlational analyses suggested that subcategory information did affect the degree of difficulty that readers experienced processing the critical noun and matrix verb.

Levels of processing of normal and ambiguous sentences in different contexts

Summary An experiment was conducted to investigate the effect of depth of semantic analysis on the recall of sentences presented for comprehension. The depth of semantic analysis was varied by presenting 48 subjects with 24 unambiguous or lexically ambiguous sentences that were either preceded by a picture or not. Each picture showed either one or both interpretations of the respective ambiguous sentence. The sentence remained on display until the subject had pressed a key to indicate that he had understood its meaning. After the presentation of all the sentences the subjects were tested for recall. Ambiguous sentences were equally well understood as unambiguous sentences, but were better recalled when their ambiguity had been noticed. The subject's awareness of sentence ambiguity, and hence the depth of semantic analysis, was found to depend on the pictorial context in which the sentences were presentend. The pictorial context was also found to affect the depth of processing of unambiguous sentences, which, when presented without a picture, were more time-consuming in comprehension and less well recalled than when preceded by a picture. These findings provide the background for a discussion of the interrelations between the comprehension of sentences, the depth of their semantic processing, and the recall of these sentences.The author gratefully acknowledges the assistance of Lorenz Sichelschmidt in collecting and analyzing data and B.

Temporal course of activation of the antecedent by the reflexive in syntactically ambiguous sentences in Japanese

Three experiments examined the temporal course of the activation of an antecedent triggered by a reflexive,jibun, in syntactically ambiguous sentences in Japanese. Twenty-two students in Experiment 1 were tested for sentences where a subject word occupied the first position and an indirect object word the second, with the probe given for each word either immediately after the reflexive or at the end of the sentence. Reaction times (RTs) were faster when the probe was for subject (S-probe) than when it was for indirect object (IO-probe) irrespective of the probe position. Experiment 2 tested 22 students to determine the effect of order of mention of participant on the probe recognition time. RTs were faster for the S-probe than for the IO-probe, although the difference between the two probes was smaller when the probe was given immediately after the reflexive. Experiment 3 tested 22 students to examine the effect of context on an activation pattern. RTs were lower for the S-probe than for the IO-probe, though no difference was found between them for the probe given at the end of the sentence. Findings were interpreted as supporting the single-interpretation model for on-line analysis of syntactically ambiguous sentences and also the immediate-activation model in an assignment of the reflexive to its antecedent.     

Ambiguity in the brain: what brain imaging reveals about the processing of syntactically ambiguous sentences

Two fMRI studies investigated the time course and amplitude of brain activity in language-related areas during the processing of syntactically ambiguous sentences. In Experiment 1, higher levels of activation were found during the reading of unpreferred syntactic structures as well as more complex structures. In Experiments 2A and 2B higher levels of brain activation were found for ambiguous sentences compared with unambiguous sentences matched for syntactic complexity, even when the ambiguities were resolved in favor of the preferred syntactic construction (despite the absence of this difference in previous reading time results). Although results can be reconciled with either serial or parallel models of sentence parsing, they arguably fit better into the parallel framework. Serial models can admittedly be made consistent but only by including a parallel component. The fMRI data indicate the involvement of a parallel component in syntactic parsing that might be either a selection mechanism or a construction of multiple parses.     

ERP evidence for telicity effects on syntactic processing in garden-path sentences

Verbs contain multifaceted information about both the semantics of an action, and potential argument structures. Linguistic theory classifies verbs according to whether the denoted action has an inherent (telic) end-point (fall, awaken), or whether it is considered homogenous, or atelic (read, worship). The aim of our study was to examine how this distinction influences on-line sentence processing, investigating the effects of verbal telicity on the ease of syntactic re-analysis of Object reduced relative clauses. Event-related brain potentials (ERPs) were recorded from 22 English speakers as they read sentences in which the main verb was either telic or atelic, e.g., “The actress awakened/worshipped by the writer left in a hurry”. ERPs elicited by telic and atelic verbs, the preposition “by” introducing the second argument (Agent), and the second argument itself, e.g., “writer”, were compared. Additionally, participants were grouped according to receptive syntactic proficiency: normal (NP) or high (HP). ERPs from the NP group first diverged at the second argument, with the atelic condition eliciting larger amplitude negativity at the N100, and continuing to the P200 interval. In contrast, ERPs from the HP group first diverged earlier in the sentence, on the word “by”. ERPs elicited by “by” in the atelic condition were also characterized by increased negativity, in this case significant at P200 and Anterior Negativity between 320 and 500 ms post stimulus onset. Our results support the postulated conceptual/semantic distinction underlying the two verb categories, and demonstrate that world-knowledge about actions designated by verbs and syntactic proficiency are reflected in on-line processing of sentence structure.     

The processing of constituent characters in Kanji words in proofreading Japanese sentences

In two proofreading experiments the processing of constituent characters in Japanese words was studied. In Experiment 1, the subjects were asked to detect misspellings on a CRT displaying a character, a word, a phrase, or a full sentence at a time. In Experiment 2, a comprehension task was added to make sure that the subjects read sentences in left-to right fashion with comprehension. Both experiments showed consistent results. The manipulation of visual similarity between misspelled and correct characters revealed that misspellings having supraletter features nearly identical to the correct characters received lower detection rates, and that the subjects utilized word-level information when proofreading. The disruptive effect on character processing in reading a sentence that was expected from the unitization hypothesis (Healy & Drewnowski, 1983) was not found. The constituent-level units in Japanese words are considered to be functionally equivalent to word-level units, instead of constituting a hierarchy.Part of this research was presented at the Second International Conference on Visual Search, Durham, U.K., September 1990     

A new look at the syntax-discourse interface: the use of binding principles in sentence processing

Within Generative Grammar, binding constraints on co-reference are usually defined in syntactic terms. However, some researchers have pointed out examples in which syntactically defined binding constraints do not seem to apply, proposing instead that a complete account of linguistic co-reference needs to consider notions of discourse structure. There have been several proposals in the literature for the division of labor between syntax and discourse in the definition of binding constraints. In this paper, we review these proposals in the context of recent work that applies on-line techniques to explore the roles of syntactic and discourse preferences in terms of the time course with which they become active during sentence comprehension. Some of this research suggests that (syntactic) binding principles may be momentarily applied during processing, even in cases in which the final interpretation suggests otherwise. We end the paper by considering the theoretical and methodological implications of this view.     

Effects of animacy and noun-phrase relatedness on the processing of complex sentences

Previous work has suggested that syntactically complex object-extracted relative clauses are easier to process when the head noun phrase (NP1) is inanimate and the embedded noun phrase (NP2) is animate, as compared with the reverse animacy configuration, with differences in processing difficulty beginning as early as NP2 (e.g., The article that the senator . . . vs. The senator that the article . . .). Two eye-tracking-while-reading experiments were conducted to better understand the source of this effect. Experiment 1 showed that having an inanimate NP1 facilitated processing even when NP2 was held constant. Experiment 2 manipulated both animacy of NP1 and the degree of semantic relatedness between the critical NPs. When NP1 and NP2 were paired arbitrarily, the early animacy effect emerged at NP2. When NP1 and NP2 were semantically related, this effect disappeared, with effects of NP1 animacy emerging in later processing stages for both the related and arbitrary conditions. The results indicate that differences in the animacy of NP1 influence early processing of complex sentences only when the critical NPs share no meaningful relationship.     

There's more to emotion than meets the eye: A processing bias for neutral content in the domain of emotional prosody

Research on emotion processing in the visual modality suggests a processing advantage for emotionally salient stimuli, even at early sensory stages; however, results concerning the auditory correlates are inconsistent. We present two experiments that employed a gating paradigm to investigate emotional prosody. In Experiment 1, participants heard successively building segments of Jabberwocky “sentences” spoken with happy, angry, or neutral intonation. After each segment, participants indicated the emotion conveyed and rated their confidence in their decision. Participants in Experiment 2 also heard Jabberwocky “sentences” in successive increments, with half discriminating happy from neutral prosody, and half discriminating angry from neutral prosody. Participants in both experiments identified neutral prosody more rapidly and accurately than happy or angry prosody. Confidence ratings were greater for neutral sentences, and error patterns also indicated a bias for recognising neutral prosody. Taken together, results suggest that enhanced processing of emotional content may be constrained by stimulus modality.     

Hemispheric asymmetries in processing L1 and L2 idioms: effects of salience and context

This study investigates the contribution of the left and right hemispheres to the comprehension of bilingual figurative language and the joint effects of salience and context on the differential cerebral involvement in idiom processing. The divided visual field and the lexical decision priming paradigms were employed to examine the activation of salient and nonsalient ambiguous idiom interpretations (i.e., literal vs. non-literal) in the two hemispheres. Literally plausible ambiguous idioms, L1 (Polish) and L2 (English), were embedded in unconstraining ambiguous (e.g., I knew he kept an ace up his sleeve) or constraining unambiguous context clearly favoring their conventional idiomatic interpretation (e.g., The debating president kept an ace up his sleeve). Idioms were presented centrally, followed by laterally presented targets related to the figurative (e.g., GAIN) or literal (e.g., SHIRT) meaning of the idiom and displayed at Interstimulus Intervals (ISIs) of 0 ms (Experiment 1), 300 ms (Experiment 2), and 800 ms (Experiment 3). Results indicate that context and salience effects are significantly modulated by the language (native vs. nonnative) of the stimulus materials being presented to each hemisphere. Literal facilitation was found for L2 idioms in all three ISI conditions, which supports the notion of the special status that literal meanings of L2 idioms enjoy in the course of their processing by nonnative language users. No significant differences were found between the right and left hemispheres in regards to their sensitivity to contextual constraints. Results are discussed in terms of the Graded Salience Hypothesis and the Fine/Coarse Coding Theory.

Interpretation of ambiguous information in clinical depression

The present study used two cognitive tasks--a text comprehension task and a homophone task--to investigate whether clinically depressed individuals have a negative bias when interpreting ambiguous information. Previous research indicates that both tasks are sensitive to anxiety-related interpretive biases, and that the former is less prone to response bias effects. Negative memory biases were also assessed. Results showed that, compared with normal controls, depressed individuals made more negative interpretations on the homophone task, and they also showed an enhanced negative recall bias. However, the groups did not differ in interpretative bias on the text comprehension task. Possible explanations of the results are discussed, including the potential influences of self-referent processing and response bias.     

The discounting of ambiguous information in economic decision making

In three experimental studies we investigated how decision makers respond to ambiguous information about costs and benefits. In Experiment 1, we studied the effect of ambiguity about prior costs. Experiments 2 and 3 focused on the effect of ambiguity about future outcomes. The collective results of the three studies suggest that decision makers discount ambiguous information. The findings are related to insights on the disjunction effect, the sunk cost effect, transaction decoupling, and ambiguity aversion. Copyright © 2003 John Wiley & Sons, Ltd.     

Anticipating explanations in relative clause processing

We show that comprehenders’ expectations about upcoming discourse coherence relations influence the resolution of local structural ambiguity. We employ cases in which two clauses share both a syntactic relationship and a discourse relationship, and hence in which syntactic and discourse processing might be expected to interact. An off-line sentence-completion study and an on-line self-paced reading study examined readers’ expectations for high/low relative-clause attachments following implicit-causality and non-implicit causality verbs (John detests/babysits the children of the musician who…). In the off-line study, the widely reported low-attachment preference for English is observed in the non-implicit causality condition, but this preference gives way to more high attachments in the implicit-causality condition in cases in which (i) the verb’s causally implicated referent occupies the high-attachment position and (ii) the relative clause provides an explanation for the event described by the matrix clause (e.g., …who are arrogant and rude). In the on-line study, a similar preference for high attachment emerges in the implicit-causality context—crucially, before the occurrence of any linguistic evidence that the RC does in fact provide an explanation—whereas the low-attachment preference is consistent elsewhere. These findings constitute the first demonstration that expectations about ensuing discourse coherence relationships can elicit full reversals in syntactic attachment preferences, and that these discourse-level expectations can affect on-line disambiguation as rapidly as lexical and morphosyntactic cues.     

Effects of NP type on the resolution of word-order ambiguities

Locally ambiguous NP₁ NP₂ V clauses in Dutch are preferably assigned a subject-object rather than an object-subject interpretation, presumably on the basis of structurally based principles such as the Active-Filler Strategy. The present study investigates whether this preference can be affected by a nonconfigurational factor, namely the nature of NP₂. The type of an NP (indefinite NPs, full definite NPs, pronouns) conveys information about the discourse status of the NP referent, which, in turn, is associated with a specific syntactic position. More specifically, pronouns are used to refer to given, salient entities in the discourse (topics); and NPs with such referents are generally encoded in subject position. A self-paced reading experiment shows that NP₁ NP₂ V relative clauses are preferably interpreted as subject-object when NP₂ is a full definite NP (e.g., de vrouwen the women), but not when NP₂ is the second person pronoun jullie (you-PL). This suggests that the structural bias for a subject-first order is not as strong as has been previously assumed, but is influenced by discourse information encoded in the NPs. Implications for parsing models are discussed.     

Influence of duration and location of pauses on comprehension of a temporarily ambiguous utterance in adults

Despite the important influence of prosody on comprehension, it remains unclear how the individual parameters of prosody contribute to the process. Therefore, this study examined the magnitude of one prosodic cue, duration of the pause, that precipitates comprehension when the pause is located either early or late in an ambiguous phrase. Adults between the ages of 20 and 40 years (men: M = 27.9, SD = 4.1, women: M = 26.2, SD = 3.7) listened to a series of phrases and made a decision regarding the meaning of each phrase. Analysis of variance for repeated measures yielded main effects of location and duration of pause with an interaction of location by duration. When the pause was located early in the phrase, a longer pause was needed before adults selected the correct meaning. However, when the pause was located later in the phrase, a pause of much shorter duration was sufficient for accurate selection of the intended meaning. A difference in pause duration of 175 msec. was found between the two locations studied.
