Distinctiveness and encoding effects in online sentence comprehension.

In explicit memory recall and recognition tasks, elaboration and contextual isolation both facilitate memory performance. Here, we investigate these effects in the context of sentence processing: targets for retrieval during online sentence processing of English object relative clause constructions differ in the amount of elaboration associated with the target noun phrase, or the homogeneity of superficial features (text color). Experiment 1 shows that greater elaboration for targets during the encoding phase reduces reading times at retrieval sites, but elaboration of non-targets has considerably weaker effects. Experiment 2 illustrates that processing isolated superficial features of target noun phrases—here, a green word in a sentence with words colored white—does not lead to enhanced memory performance, despite triggering longer encoding times. These results are interpreted in the light of the memory models of Nairne, 1990, 2001, 2006, which state that encoding remnants contribute to the set of retrieval cues that provide the basis for similarity-based interference effects.

A dual task procedure combined with rapid serial visual presentation to test attentional blink for nontargets.

When viewers search for targets in a rapid serial visual presentation (RSVP) stream, if two targets are presented within about 500 msec of each other, the first target may be easy to spot but the second is likely to be missed. This phenomenon of attentional blink (AB) has been widely studied to probe the temporal capacity of attention for detecting visual targets. However, with the typical procedure of AB experiments, it is not possible to examine how the processing of non-target items in RSVP may be affected by attention. This paper describes a novel dual task procedure combined with RSVP to test effects of AB for nontargets at varied stimulus onset asynchronies (SOAs). In an exemplar experiment, a target category was first displayed, followed by a sequence of 8 nouns. If one of the nouns belonged to the target category, participants would respond 'yes' at the end of the sequence, otherwise participants would respond 'no'. Two 2-alternative forced choice memory tasks followed the response to determine if participants remembered the words immediately before or after the target, as well as a random word from another part of the sequence. In a second exemplar experiment, the same design was used, except that 1) the memory task was counterbalanced into two groups with SOAs of either 120 or 240 msec and 2) three memory tasks followed the sequence and tested remembrance for nontarget nouns in the sequence that could be anywhere from 3 items prior the target noun position to 3 items following the target noun position. Representative results from a previously published study demonstrate that our procedure can be used to examine divergent effects of attention that not only enhance targets but also suppress nontargets. Here we show results from a representative participant that replicated the previous finding.

Two sides of gender: ERP evidence for the presence of two routes during gender agreement processing

The present ERP study aimed at providing evidence for the existence of two routes in the brain for the processing of morphosyntactic features during language comprehension; a lexical route which retrieves grammatical properties stored in the lexicon without reliance on formal cues, and a form-based route that takes advantage of sub-lexical units strongly related to a specific grammatical class. In the experiment, we investigated grammatical gender agreement processing in Spanish article–noun word pairs using a grammaticality judgment task. Article–noun pairs either agreed or did not agree in gender. Noun transparency was manipulated such that the ending could be strongly associated with a specific gender class (i.e., transparent nouns) or not (i.e., opaque nouns). A visual half-field method was employed and ERPs were recorded in response to the target nouns in order to disentangle the initial hemisphere-specific computations of gender processing. ERP results showed that, while both hemispheres compute agreement dependencies, the left hemisphere is sensitive to the presence of formal gender cues at an early stage (i.e., 350–500ms) indicating the presence of a form-based route. The right hemisphere showed an ERP effect of transparency, but later than the left hemisphere (i.e., 500–750ms). These findings confirm the presence of two routes to gender, which can be differently used depending on the availability of transparent endings. In addition, the results showed hemispheric differences in the time course of the form-based route.

Is it or isn’t it: Listeners make rapid use of prosody to infer speaker meanings

A visual world experiment examined the time course for pragmatic inferences derived from visual context and contrastive intonation contours. We used the construction It looks like an X pronounced with either (a) a H* pitch accent on the final noun and a low boundary tone, or (b) a contrastive L+H* pitch accent and a rising boundary tone, a contour that can support contrastive inference (e.g., It LOOKSL+H*like a zebraL-H%… (but it is not)). When the visual display contained a single related set of contrasting pictures (e.g. a zebra vs. a zebra-like animal), effects of LOOKSL+H* emerged prior to the processing of phonemic information from the target noun. The results indicate that the prosodic processing is incremental and guided by contextually-supported expectations. Additional analyses ruled out explanations based on context-independent heuristics that might substitute for online computation of contrast.

Do patients with schizophrenia use prosody to encode contrastive discourse status?

Patients with schizophrenia (SZ) often display social cognition disorders, including Theory of Mind (ToM) impairments and communication disruptions. Thought language disorders appear to be primarily a disruption of pragmatics, SZ can also experience difficulties at other linguistic levels including the prosodic one. Here, using an interactive paradigm, we showed that SZ individuals did not use prosodic phrasing to encode the contrastive status of discourse referents in French. We used a semi-spontaneous task to elicit noun-adjective pairs in which the noun in the second noun-adjective fragment was identical to the noun in the first fragment (e.g., BONBONS marron “brown candies” vs. BONBONS violets “purple candies”) or could contrast with it (e.g., BOUGIES violettes “purple candles” vs. BONBONS violets “purple candies”). We found that healthy controls parsed the target noun in the second noun-adjective fragment separately from the color adjective, to warn their interlocutor that this noun constituted a contrastive entity (e.g., BOUGIES violettes followed by [BONBONS] [violets]) compared to when it referred to the same object as in the first fragment (e.g., BONBONS marron followed by [BONBONS violets]). On the contrary, SZ individuals did not use prosodic phrasing to encode contrastive status of target nouns. In addition, SZ's difficulties to use prosody of contrast were correlated to their score in a classical ToM task (i.e., the hinting task). Taken together, our data provide evidence that SZ patients exhibit difficulties to prosodically encode discourse statuses and sketch a potential relationship between ToM and the use of linguistic prosody.

Idiosyncratic Grammars: Syntactic Processing in Second Language Comprehension Uses Subjective Feature Representations

Learning the syntax of a second language (L2) often represents a big challenge to L2 learners. Previous research on syntactic processing in L2 has mainly focused on how L2 speakers respond to "objective" syntactic violations, that is, phrases that are incorrect by native standards. In this study, we investigate how L2 learners, in particular those of less than near-native proficiency, process phrases that deviate from their own, "subjective," and often incorrect syntactic representations, that is, whether they use these subjective and idiosyncratic representations during sentence comprehension. We study this within the domain of grammatical gender in a population of German learners of Dutch, for which systematic errors of grammatical gender are well documented. These L2 learners as well as a control group of Dutch native speakers read Dutch sentences containing gender-marked determiner-noun phrases in which gender agreement was either (objectively) correct or incorrect. Furthermore, the noun targets were selected such that, in a high proportion of nouns, objective and subjective correctness would differ for German learners. The ERP results show a syntactic violation effect (P600) for objective gender agreement violations for native, but not for nonnative speakers. However, when the items were re-sorted for the L2 speakers according to subjective correctness (as assessed offline), the P600 effect emerged as well. Thus, rather than being insensitive to violations of gender agreement, L2 speakers are similarly sensitive as native speakers but base their sensitivity on their subjective-sometimes incorrect-representations.

Lexical Retrieval of Nouns and Verbs in a Sentence Completion Task.

This study explored noun and verb retrieval using a sentence completion task to expand upon previous findings from picture naming tasks. Participants completed sentences missing either a target noun or verb in the final position. Non-target responses were coded for substitution type, imageability and frequency. Like picture naming, nouns and verbs differed in non-target substitution type-within-category substitutions were primarily nouns and out-of-category substitutions were primarily verbs. Imageability predicted multiple substitution types for both word classes, whereas frequency predicted noun substitution types but not verbs. Findings support theories of noun and verb differences in semantic retrieval, showing the robustness of this effect across methodologies, and shed new light on the influence of imageability and frequency during semantic retrieval.

Can the meaning of multiple words be integrated unconsciously?

What are the limits of unconscious language processing? Can language circuits process simple grammatical constructions unconsciously and integrate the meaning of several unseen words? Using behavioural priming and electroencephalography (EEG), we studied a specific rule-based linguistic operation traditionally thought to require conscious cognitive control: the negation of valence. In a masked priming paradigm, two masked words were successively (Experiment 1) or simultaneously presented (Experiment 2), a modifier ('not'/'very') and an adjective (e.g. 'good'/'bad'), followed by a visible target noun (e.g. 'peace'/'murder'). Subjects indicated whether the target noun had a positive or negative valence. The combination of these three words could either be contextually consistent (e.g. 'very bad - murder') or inconsistent (e.g. 'not bad - murder'). EEG recordings revealed that grammatical negations could unfold partly unconsciously, as reflected in similar occipito-parietal N400 effects for conscious and unconscious three-word sequences forming inconsistent combinations. However, only conscious word sequences elicited P600 effects, later in time. Overall, these results suggest that multiple unconscious words can be rapidly integrated and that an unconscious negation can automatically 'flip the sign' of an unconscious adjective. These findings not only extend the limits of subliminal combinatorial language processes, but also highlight how consciousness modulates the grammatical integration of multiple words.

Differences in the acoustic correlates of intonation in child and adult speech

During speech perception, toddlers use prosodic cues, such as pitch, in order to identify the most salient/prominent information in the discourse. This process is critical in facilitating early word recognition and learning. How do children then use these acoustic cues in their own speech in comparison to mature adult speech? The motivation for this study is to examine the acoustic correlates of intonation employed by child (mean: 2.5 years) and adult speakers of English during a guided spontaneous production task. During an interactive game, we elicit a set of target nouns and label them as one of three types: (1) new, uttered for the first time by the participant, (2) given, previously uttered at least once by the participant, or (3) contrastive, uttered in direct opposition to a previously mentioned referent. Along with labeling the pitch accent, we measured f0 range, f0 slope, duration, and intensity for each target word under these varying conditions. These measurements allow us to compare the types of pitch accents used by children and adults, and how each group employs the acoustic correlates of intonation. Identifying how these parameters are used during production is an important step in understanding speech development in early language acquisition.

The effects of paper-based DDL on the acquisition of lexico-grammatical patterns in L2 writing

AbstractThis paper examines whether and to what extent data-driven learning (DDL) activities can improve the lexico-grammatical use of abstract nouns in L2 writing. A topic-based corpus was compiled to develop concordance learning activities, and 40 Chinese students majoring in English were randomly assigned to a control group or an experimental group. At the prewriting stage, both groups were given a list of five abstract nouns: the experimental group was provided with paper-based concordance lines to study the collocations of the words, while the control group was allowed to consult dictionaries for the usage of the words. The written texts of the pre-test, immediate post-test, and delayed post-test were analysed and compared between and within groups. The results showed that the written output by the experimental group, as compared with the control group, contained a higher variety of collocational and colligational patterns and had fewer linguistic errors in using the target abstract nouns. The post-experiment learning journals and questionnaires administered to the experimental group further confirmed that concordance activities encouraged usage-based learning, helped students notice the lexical collocations and prepositional colligations of the target words, and thus improved accuracy and complexity in their productive language. Despite these positive findings, potential problems of using concordance activities for independent learning were also reflected in the students’ written output and reported in the learning journals.

Semantic preview benefit in reading English: The effect of initial letter capitalization.

A major controversy in reading research is whether semantic information is obtained from the word to the right of the currently fixated word (word n + 1). Although most evidence has been negative in English, semantic preview benefit has been observed for readers of Chinese and German. In the present experiment, we investigated whether the discrepancy between English and German may be attributable to a difference in visual properties of the orthography: the first letter of a noun is always capitalized in German, but is only occasionally capitalized in English. This visually salient property may draw greater attention to the word during parafoveal preview and thus increase preview benefit generally (and lead to a greater opportunity for semantic preview benefit). We used English target nouns that can either be capitalized (e.g., We went to the critically acclaimed Ballet of Paris while on vacation.) or not (e.g., We went to the critically acclaimed ballet that was showing in Paris.) and manipulated the capitalization of the preview accordingly, to determine whether capitalization modulates preview benefit in English. The gaze-contingent boundary paradigm was used with identical, semantically related, and unrelated previews. Consistent with our hypothesis, we found numerically larger preview benefits when the preview/target was capitalized than when it was lowercase. Crucially, semantic preview benefit was not observed when the preview/target word was not capitalized, but was observed when the preview/target word was capitalized.

音乐启动刺激的跨通道情感启动效应

以往研究表明存在跨通道情感启动效应，然而这些研究在启动材料选择上存在时长短、缺乏生态效度等问题，本研究首次采用长时呈现的来自真实歌曲的纯音乐片段为启动刺激，以30名在校大学生为被试，进一步对该问题进行探讨。研究结果显示：启动音乐效价与目标词效价一致时的正确率显著高于不一致时的正确率，但两者在反应时上无显著差异；当目标词为中性时，被试倾向于选择与启动效价一致的反应效价，但不同启动音乐效价对被试的选择反应时没有显著影响。上述结果表明在知觉范围内存在无意识的跨通道情感启动效应，为拓展情感启动的实验范式以及进一步探讨情感启动效应的心理发生机制提供了依据。 Previous studies have proved that there exist cross-modal affective priming, but those still remain some flaws, such as short exposure time and ecological validity lacking in the selection of priming materials. This research firstly chose simple music clips lasting for a long time as priming stimulus, with 30 undergraduates as participants, to explore the issue further. The results were as follows: when the valence of priming music and the one of target stimulus were consistent, participants’ accuracy was significant higher than it when not, but there was no apparent difference in reaction time; when presenting a neutral noun target, participants were inclined to choose the valence that was consistent with the priming valence, and similarly, there existed no difference in reaction time when the valence of priming music differed. The research indicated that there existed unconscious cross-modal affective priming effect. This study provided important foundation for the expansion of the affective priming paradigm as well as the mental mechanism of affective priming effect.

Articulatory and lexical repetition effects on durational reduction: speaker experience vs. common ground

Speakers tend to reduce the duration of words that they have heard or spoken recently. We examine the cognitive mechanisms behind duration variation, focusing on the contributions of speaker-internal constraints and audience design. In three experiments, we asked speakers to give instructions to listeners about how to move objects. In Experiment 1, the instruction was preceded by an auditory prime, which elicited reduced spoken word duration on a target noun in a speaker-privilege condition, and additional reduction on a determiner in a mutual-knowledge condition. In Experiments 2a and 2b, we tested the related hypothesis that the speaker's experience articulating the target leads to fluent processing above and beyond fluency in other processing, such as lexical selection. While prior articulation of the target led to greater reduction than just thinking about the word (Experiment 2a), saying the prime led to equal reduction as hearing the prime (Experiment 2b). The pattern of results leads to the conclusion that facilitated processing, perhaps brought on primarily as a function of having heard a word, is a major contributor to durational reduction in running speech. While audience design also has a small effect, its effect may also be mediated by processing fluency.

Cognate and word class ambiguity effects in noun and verb processing

This study examined how noun and verb processing in bilingual visual word recognition are affected by within and between-language overlap. We investigated how word class ambiguous noun and verb cognates are processed by bilinguals, to see if co-activation of overlapping word forms between languages benefits from additional overlap within a language, and whether this effect is sensitive to the grammatical category of a word. Although effects of form overlap are ubiquitous in studies on nouns, little is known about such effects in verbs. In two experiments, Dutch–English bilinguals performed lexical decision tasks in L2 in which cognate status and word class ambiguity were manipulated in nouns and verbs. Responses to verb targets in both experiments showed facilitatory effects of both types of overlap. In contrast, noun targets in both experiments showed only a cognate effect, but no ambiguity effect. We argue that the difference between verbs and nouns arises because verb representations are more complex than those of nouns. As a consequence, verb processing benefits more from within-language form overlap than noun processing.

Predictability speeds up the re-analysis process: An ERP investigation of gender agreement and cloze probability

To investigate the timing relationship between lexical access and later processes, the present study compared event-related potentials (ERPs) in response to spoken Dutch sentences that were either correct or contained gender agreement violations on the article or adjective preceding the noun. The target noun was either unpredictable from the preceding sentence information (low cloze) or was preceded by a highly constraining context (high cloze) to investigate whether contextual constraints influence morphological processing of grammatical gender in real-time. In line with previous findings, gender violations elicited a clear P600 indicating processes of repair or re-analysis evoked by the gender mismatch. Low cloze items, independent of the gender mismatch, elicited an increased N400 reflecting lexical access and semantic integration difficulty. Interestingly, an interaction between gender mismatch and cloze probability occurred in the early portion of the P600 time window, with the P600 starting significantly later in the low cloze conditions as compared to the high cloze conditions, although they had the same amplitude in the later part of the window. These results indicate that semantic expectancy facilitates the late processes sensitive to syntactic violations, suggesting an interplay between semantics and syntax in later stages of processing and supporting interactive accounts of language comprehension.

Function Words Constrain On-Line Recognition of Verbs and Nouns in French 18-Month-Olds

In this experiment using the conditioned head-turn procedure, 18-month-old French-learning toddlers were trained to respond to either a target noun (“la balle”/the ball) or a target verb (“je mange”/I eat). They were then tested on target word recognition in two syntactic contexts: the target word was preceded either by a correct function word (“une balle”/a ball or “on mange”/they eat), or by an incorrect function word, signaling a word from the other category (*“on balle”/they ball or *“une mange”/a eat). We showed that 18-month-olds exploit the syntactic context on-line to recognize the target word: verbs were recognized when preceded by a personal pronoun but not when preceded by a determiner and vice-versa for nouns. These results suggest that 18-month-olds already know noun and verb contexts. As a result, they might be able to exploit them to categorize unknown words and constrain their possible meaning (nouns typically refer to objects whereas verbs typically refer to actions).

The role of commonality, distinctiveness and importance of semantic features in persons with aphasia

Objective: Semantic feature approaches are frequently included in treatment for people with aphasia. The present study investigated the role of distinctiveness and importance in the semantic feature knowledge of people with aphasia. The relationships between feature knowledge and the ability to choose among semantically-related foils, comprehension and naming abilities were examined.Methods: Participants distinguished target nouns from related foils and completed a sorting task involving mid-importance common (MIC), mid-importance distinctive (MID), low-importance common (LIC) and low-importance distinctive (LID) features. Participants also completed sub-tests from the short version of the Boston Diagnostic Aphasia Examination—Third Edition (BDAE-3) and Boston Naming Test—Second Edition (BNT-2). Participants were divided into two groups based on ability to accurately select target nouns from semantically-related foils.Results: Group 1, participants with intact ability to choose among related foils, was significantly less impaired with the identification of distinctive features than Group 2, those with difficulty choosing among related foils. Importance was not a significant factor when comparing mid-importance to low-importance features.Conclusions: These results suggest that distinctive feature knowledge contributes in a significant way to the integrity of semantic representations in people with aphasia which can influence their performance of language tasks.

Delayed use of fundamental frequency (F0) rise in non-native speech segmentation

Research has shown that second/foreign language (L2) speech segmentation is less efficient than native language (L1) segmentation, because L2 learners cannot suppress L1 segmentation routines. This study uses visual-world eye-tracking to determine whether English learners of French can learn to use F0 for locating word-final boundaries in French. F0 rise is often word-initial in English but often word-final in French. Native French speakers and English learners of French heard sentences where lexical competitors were created between the target noun and the following adjective (stimulus: chat grincheux ‘cranky cat’; target: chat ‘cat’; competitor: chagrin ‘sorrow’). The target was either accented or unaccented, and the stimuli were either natural or resynthesized (swapped F0 between accented and unaccented targets). Participants selected the word they heard from given options (target, competitor, distracters), and fixations were recorded from target-word onset. Accuracy (word selection): learners, but not natives, were more accurate for target words with F0 rise than without it. Fixations: natives, but not learners, showed higher differential proportions of target and competitor fixations for target words with F0 rise than without it. Proficiency did not interact with the variables. This suggests that L2 learners’ use of F0 rise is delayed compared to that of natives.

Conditional automaticity in subliminal morphosyntactic priming

We used a gender-classification task to test the principles of subliminal morphosyntactic priming. In Experiment 1, masked, subliminal feminine or masculine articles were used as primes. They preceded a visible target noun. Subliminal articles either had a morphosyntactically congruent or incongruent gender with the targets. In a gender-classification task of the target nouns, subliminal articles primed the responses: responses were faster in congruent than incongruent conditions (Experiment 1). In Experiment 2, we tested whether this congruence effect depended on gender relevance. In line with a relevance-dependence, the congruence effect only occurred in a gender-classification task but was absent in another categorical discrimination of the target nouns (Experiment 2). The congruence effect also depended on correct word order. It was diminished when nouns preceded articles (Experiment 3). Finally, the congruence effect was replicated with a larger set of targets but only for masculine targets (Experiment 4). Results are discussed in light of theories of subliminal priming in general and of subliminal syntactic priming in particular.

Evaluating Word in Phrase: The Modulation Effect of Emotional Context on Word Comprehension

The present study aims to explore the influence of emotional context on word evaluation. Participants were asked to read an "adjective +noun" phrase, where the adjective could be a positive or negative word, and the noun could be a positive, neutral or negative word, and then to make an emotional evaluation on the emotional tone of the target noun based on a 9-point Likert scale. In a control condition, an isolated noun was presented with no context. Results showed that positive context made the evaluation of target words bias toward positive tone, while negative context shaped the evaluation of target words toward negative tone. The modulatory effect of negative context was greater than that of positive context in shaping evaluation of emotional words with opposite valence. Moreover, the modulatory effect of emotional context was constrained by the inherent meaning of target word. The present study demonstrated the flexibility as well as the relative stability of emotional meaning of word.
