Differentiating among pragmatic uses of words through timed sensicality judgments
Pragmatic and cognitive accounts of figurative language posit a difference between metaphor and metonymy in terms of underlying conceptual operations. Recently, other pragmatic uses of words have been accounted for in the Relevance Theory framework, such as approximation, described in terms of conceptual adjustment that varies in degree and direction with respect to the case of metaphor. Despite the theoretical distinctions, there is very poor experimental evidence addressing the metaphor/metonymy distinction, and none concerning approximation. Here we used meticulously built materials to investigate the interpretation mechanisms of these three phenomena through timed sensicality judgments.…
Topicality matters: Position-specific demands on Chinese discourse processing
We report an event-related potential study designed to explore the nature of context-induced topicality in Chinese discourse processing. Topic is what an utterance is about and represents the most prominent discourse element, which occurs sentence-initially in Chinese. We tested question-answer pairs consisting of topic and non-topic questions followed by different continuations (Topic-Continuity, Topic-Shift, Novel-Topic). ERPs were measured at distinct sentential positions and revealed that sentence-initially information processing is guided by topicality, which affects N400 and Late Positivity effects alike. In non-initial positions, the given-new distinction is the dominant principle, a…
Age-Related Changes in Predictive Capacity Versus Internal Model Adaptability: Electrophysiological Evidence that Individual Differences Outweigh Effects of Age
Hierarchical predictive coding has been identified as a possible unifying principle of brain function, and recent work in cognitive neuroscience has examined how it may be affected by age related changes. Using language comprehension as a test case, the present study aimed to dissociate age-related changes in prediction generation versus internal model adaptation following a prediction error. Event related brain potentials (ERPs) were measured in a group of older adults (60-81 years; n = 40) as they read sentences of the form "The opposite of black is white/yellow/nice." Replicating previous work in young adults, results showed a target related P300 for the expected antonym ("white"; an eff…
Constraints on ontology changing complexation processes: Evidence from event-related brain potentials
This paper investigates complex anaphoric reference (i.e., when an anaphor refers to a propositionally structured referent). Complex anaphors (e.g., this process, this event) differ in their ontological feature setup, and the ontological type assigned to a referent can change due to the lexical meaning of the complex anaphor. Previous research has proposed that such changes have to comply with an ontological ‘abstractness constraint’ restricting the direction of ontological change. We present an event-related potential study that provides evidence that violations of the abstractness constraint result in processing costs. The data reveal that violating this constraint by shifting the referen…
Context and topic marking affect distinct processes during discourse comprehension in Japanese
Abstract In languages like English or German, definite and indefinite markers serve to distinguish given/old from new information in the discourse model. Japanese, in contrast, lacks definiteness markers, but has a topic marker. The present paper examines how the information status of a noun phrase (NP) in Japanese is represented and integrated into the discourse model. An ERP experiment investigated the processing of topic-marked and non-topic-marked NPs following three different context sentences (making available a given, inferred, or new reading). The results revealed an increase in the N400 as a function of contextual cueing, i.e. the less accessible a referential expression is in the …
Event-related brain potentials of masked repetition and semantic priming while listening to sentences.
We combined for the first time electrophysiological measures and masked priming technique in sentential context, by setting up a cross-modal masked priming paradigm involving the auditory presentation of sentences. ERPs were time-locked to an auditorily presented word that was preceded by a repeated, related or unrelated pattern masked prime. We registered a two-way N400-difference between unrelated and related/repeated primes, followed by a late positive component (LPC) for repetition priming. Related primes appear to facilitate the lexical-semantic processing of the target to the same extent repeated primes do (equally attenuated N400). Repetition priming exerts additional demands (LPC), …
Register affects language comprehension: ERP evidence from article omission in newspaper headlines
Abstract Language processing involving syntax-discourse interface operations has been claimed to be particularly resource-consuming. In production, this additional complexity is claimed to be the source of article omission in the speech of young children and certain language-impaired speakers. In comprehension, article omission in some “special registers” (e.g., newspaper headlines) has been attributed to the trade-off between spending more processing resources and increasing processing speed. We investigated the comprehension of noun phrases (NPs) with and without articles (e.g., (a) policeman arrests (a) monk) when readers were or were not aware of reading headlines by recording electroph…
New is not always costly: evidence from online processing of topic and contrast in Japanese.
Two visual ERP experiments were conducted to investigate topic and contrast assigned by various cues such as discourse context, sentential position and marker during referential processing in Japanese. Experiment 1 showed that there was no N400-difference for new vs. given noun phrases (NPs) when the new NP was expected (contrastively focused) based on its preceding context and sentential position. Experiment 2 further revealed that the N400 for new NPs can be modulated by the NP’s contrastive meaning (exhausitivity) induced from the marker. Both experiments also showed that new NPs engendered an increased Late Positivity. The reduced N400 for new vs. given supports an expectation-based lin…
(De-)Accentuation and the Processing of Information Status: Evidence from Event-Related Brain Potentials
The paper reports on a perception experiment in German that investigated the neuro-cognitive processing of information structural concepts and their prosodic marking using event-related brain potentials (ERPs). Experimental conditions controlled the information status (given vs. new) of referring and non-referring target expressions (nouns vs. adjectives) and were elicited via context sentences, which did not – unlike most previous ERP studies in the field – trigger an explicit focus expectation. Target utterances displayed prosodic realizations of the critical words which differed in accent position and accent type. Electrophysiological results showed an effect of information status, maxi…
Definiteness Marking Shows Late Effects during Discourse Processing: Evidence from ERPs
This paper investigates the processing of indefinite and definite noun phrases in discourse. It presents data from an Event-Related brain Potential (ERP) study that contrasted definite and indefinite noun phrases following three distinct context sentences. The data suggest that coherence considerations influence early processing stages, while morphological definiteness features only affect later stages during reference resolution. In addition, the processing of a definite determiner (prior to encountering the subsequent noun) exerts processing demands, supporting the functional contribution of definiteness marking. Supplementary data from a plausibility questionnaire and two completion stud…
Pitch accent type affects the N400 during referential processing
Discourse processing depends on semantic memory as well as maintaining and updating of a mental model. Using event-related potentials, we investigated how a referent's information status (new, accessible, given) is processed in combination with three different prosodic realizations (an appropriate accent and two inappropriate accents). The data reveal a biphasic N400-late positivity pattern, indicating that prosodic information affects an early discourse linking stage, during which prominence information reflecting a referent's accessibility is computed (N400), and a later discourse updating stage, during which conflicts between prosodic information and a referent's actual information statu…
Positional influences on information packaging: Insights from topological fields in German
Abstract We present three event-related potential studies that investigated the contribution of givenness and position-induced topicality (what a sentence is about) to information processing. The studies compared two types of referential expressions (given and inferred noun phrases (NPs)) in distinct sentential positions. The data revealed position-specific effects, reflected by an interaction of topicality and givenness: inferred NPs registered a more pronounced Late Positivity than given NPs in the canonical sentence-medial position, but not sentence-initially (Experiment 1). Additionally, there was a stable effect of givenness across positions, reflected by an N400 for inferred over give…
Perspective in the Processing of the Chinese Reflexive ziji: ERP Evidence
We investigated the comprehension of the Chinese reflexive ziji, which is typically subject to long-distance binding. However, this preference can be overridden by verb semantics (some verbs require local binding) as well as by subtle feature combinations of intervening noun phrases (NPs) (e.g., 1st/2nd person pronouns block dependencies with more distant 3rd person antecedents). The processing of ziji was examined in sentences containing two verb types (local/self-oriented, distant/other-oriented) and three different intervening NPs (1st, 2nd , 3rd person). The event-related potential data revealed an early interaction of verb and intervener: other-oriented verbs showed more processing eff…
Animacy matters: ERP evidence for the multi-dimensionality of topic-worthiness in Chinese
Abstract An event-related potential (ERP) study was conducted to investigate how animacy interacts with givenness during topic processing. Both animacy and givenness have been considered as within-discourse factors that contribute to an element׳s potential to form an optimal topic (i.e., topic-worthiness). ERPs were recorded while participants read question–answer pairs, of which the target sentence induced either a continuation or an alternation of a previously introduced topic (i.e., given vs. new). Depending on the context, a potential topic further differed in its animacy from the preceding one (i.e., animate vs. inanimate). The data revealed a robust givenness effect with an N400 reduc…
Reversibility in Chinese word formation influences target identification.
We recorded event-related brain potentials during the processing of visually presented compound words in Mandarin Chinese. We capitalized on a particular characteristic of Chinese word formation, where two constituents can be combined in two different orders (A+B or B+A), yielding distinct meanings-so-called "reversible words". By investigating the impact of structural reversibility on the processing of compounds in Chinese during a lexical decision task, the present study revealed a pronounced difference between reversible and non-reversible words. Analyses revealed a more enhanced negativity (N400) for reversible words, reflecting demands during semantic processing, followed by a P300-lik…
