Effect of repetition on grammaticality judgments under objective and subjective self-awareness conditions

Three experiments were performed to investigate the differential effect of repeated presentation of sentences on judgments of grammaticality under the two mental states of objective and subjective self-awareness. In Experiment 1, 22 students judged the relative grammaticality of sentences twice, receiving a repetition treatment between the two judgments. During the repetition phase, they were exposed to a repeated presentation of sentences. The findings showed that repetition makes a judgment criterion more stringent on judgments after repetition than on those before repetition for the subjectively self-aware subjects, while it does not influence the judgments for the objectively self-aware subjects. Experiment 2 was run using a revised procedure with 26 students. The findings showed the expected, interaction, such that the repetition makes a criterion stringent for the subjectively self-aware subjects while it makes the criterion lenient for the objectively self-aware subjects. Experiment 3 examined with 12 students whether the finding for the latter subjects could be explained, by divided attention theory in a concurrent task condition. The findings showed no change of judgment criterion. These findings indicate that repeated exposure to the sentences exerts differential effects on grammaticality judgments dependent on whether the subjects are objectively or subjectively self-aware.     

Judgments of grammaticality of sentences with a differing number of arguments: a comparison of English and Japanese speakers

This study explored native speakers' linguistic intuition as revealed in judging the grammaticality of sentences. Speakers of English (n = 36) and Japanese (n = 57) judged the relative grammaticality of sentences involving a verb which occurred together with one, two or three arguments. Findings showed that English speakers were more affected by the number of arguments in sentences. They judged sentences having three arguments as grammatical most often and ones having one or two arguments as grammatical less often. However, Japanese speakers gave rather similar and more grammatical judgments regardless of the number of arguments in sentences. The findings indicate a difference in tightness of argument structure in the two languages even when the sentences judged are simple sentences and they are given without any sentential context.     

Judgments of Grammaticality of Japanese Sentences Violating the Principle of Full Interpretation

Two experiments investigated the linguistic intuition of Japanese speakers in which they judged the grammaticality of sentences violating Chomsky's principle of Full Interpretation. Experiment 1 used bitransitive sentences, which included an extra argument that assumed a role of either subjective, dative, or objective on the one hand and that specified semantically a preceding argument or stood in par with it on the other. Findings showed that the speakers judged ungrammatical sentences involving a dative or an objective extra argument as more grammatical than those involving a subjective extra argument. Ungrammatical sentences with an extra specified argument were judged more grammatical than those with an extra par argument when the extra argument was objective. Experiment 2 used sentences that included a verbal noun (VN) comprising a noun followed by a verb, shita (did). Ungrammatical VN sentences contained two arguments given the same objective marker. These sentences were judged to be highly grammatical despite the violation of the principle. Findings suggest that speakers' actual knowledge of language is not fully consistent with the knowledge they are alleged by Chomsky to possess, including the principle of Full Interpretation.     

Syntactic Features in Reanalysis: Positive and Negative Symptoms

Meng and Bader have presented evidence that a Case conflict is a more effective cue for garden-path reanalysis than a number conflict is, for German wh-sentences with subject–object ambiguities. The preferred first-pass analysis has the wh-trace in subject position, although object position is correct. In a speeded grammaticality judgment task, perceivers accepted Case-disambiguated examples more often and more rapidly than number-disambiguated examples, although comprehension questions indicated that both were eventually understood correctly. For ungrammatical sentences, a Case mismatch error resulted in more false positive grammaticality judgments than a number mismatch error. We offer an explanation for why Case and number features differ in these two ways in their effects on sentence processing. We propose, within the Diagnosis Model of garden-path processing, that reanalysis triggered by a Case mismatch guides the parser more effectively toward the correct structure. Case is a positive symptom, which carries information about the new structure that must be built. By contrast, a number mismatch is a negative symptom; it invalidates the incorrect structure without showing how to rebuild it. This difference in the transparency of garden-path repair can also account for the greater overacceptance of Case-disambiguated ungrammatical sentences. The speeded grammaticality judgment task is designed to encourage hasty responses. Usually, these are hasty rejections of garden path sentences that, on calmer reflection, the parser would find acceptable. Conversely, over-hasty acceptance could occur if some initial progress is made in resolving a grammatical problem. Thus, a higher rate of false positives on ungrammaticals is to be expected where reanalysis proceeds successfully for a while before blocking.     

Agreement processing and attraction errors in aging: evidence from subject-verb agreement in German

Effects of aging on lexical processing are well attested, but the picture is less clear for grammatical processing. Where age differences emerge, these are usually ascribed to working-memory (WM) decline. Previous studies on the influence of WM on agreement computation have yielded inconclusive results, and work on aging and subject-verb agreement processing is lacking. In two experiments (Experiment 1: timed grammaticality judgment, Experiment 2: self-paced reading + WM test), we investigated older (OA) and younger (YA) adults’ susceptibility to agreement attraction errors. We found longer reading latencies and judgment reaction times (RTs) for OAs. Further, OAs, particularly those with low WM scores, were more accepting of sentences with attraction errors than YAs. OAs showed longer reading latencies for ungrammatical sentences, again modulated by WM, than YAs. Our results indicate that OAs have greater difficulty blocking intervening nouns from interfering with the computation of agreement dependencies. WM can modulate this effect.     

The role of intonation cues in aphasic patients' performance of the grammaticality judgment task

This study investigated the possibility that the reported success of agrammatic aphasic patients in performing auditory grammaticality judgments results from their use of intonational cues to sentence well-formedness. Two agrammatic aphasics, two anomic aphasics, and two nonagrammatic patients with comprehension deficits for semantically reversible sentences were asked to judge grammatical well-formedness in three conditions. Results in a "natural" listening condition replicated the finding of M.C. Linebarger, M.F. Schwartz, and E. M. Saffran (1983, Cognition, 13, 361-392) that agrammatic patients are sensitive to grammaticality despite poor ability to use syntatic cues in comprehension tasks. Two additional listening conditions employed signal-processed auditory stimuli in which the fundamental frequency was normal or was set at a constant level. Right-hemisphere-damaged and normal controls showed no performance deficit for judgments of monotone sentences. The aphasic patients' performance was slightly worse for both signal-processed conditions, but there was little apparent effect of removing sentence intonation on their ability to judge sentence grammaticality. These results indicate that the high levels of performance on grammaticality judgement tasks have not resulted from patients' detection of intonational cues in ungrammatical sentences.     

The conscious, the unconscious, and familiarity

This article examines the role of subjective familiarity in the implicit and explicit learning of artificial grammars. Experiment 1 found that objective measures of similarity (including fragment frequency and repetition structure) predicted ratings of familiarity, that familiarity ratings predicted grammaticality judgments, and that the extremity of familiarity ratings predicted confidence. Familiarity was further shown to predict judgments in the absence of confidence, hence contributing to above-chance guessing. Experiment 2 found that confidence developed as participants refined their knowledge of the distribution of familiarity and that differences in familiarity could be exploited prior to confidence developing. Experiment 3 found that familiarity was consciously exploited to make grammaticality judgments including those made without confidence and that familiarity could in some instances influence participants' grammaticality judgments apparently without their awareness. All 3 experiments found that knowledge distinct from familiarity was derived only under deliberate learning conditions. The results provide decisive evidence that familiarity is the essential source of knowledge in artificial grammar learning while also supporting a dual-process model of implicit and explicit learning.     

Sensitivity to inflectional morphology in agrammatism: investigation of a highly inflected language

We present the results of a study with six Serbo-Croatian-speaking agrammatic patients on a test of inflectional morphology in which subjects judged whether spoken sentences were grammatical or ungrammatical. Sensitivity to two kinds of syntactic features was investigated in these aphasic patients: (1) subcategorization rules for transitive verbs (which must be followed by a noun in the accusative case; intransitive verbs can be followed by nouns in other noun cases); (2) sensitivity to the inflectional morphology marking noun case. The test items consisted of three-word sentences (noun-verb-noun) in which verb transitivity and appropriateness of the case inflection of the following noun were manipulated. Results of the grammaticality judgment task show that both syntactic properties are preserved in these patients.     

Language,cognition, and second language grammaticality judgments

In first language research, there appear to be two predominant positions relating metalinguistic awareness to language development. One suggests that since metalinguistic awareness is related to primary language acquisition (comprehension and production), general cognitive processes perform a limited role in metalinguistic awareness. The other suggests that since metalinguistic awareness is more closely related to secondary language acquisition (reading and writing), a greater role is assumed by general cognitive processes. There have been some indirect attempts to study the role of language and cognition with respect to second language grammaticality judgments. There is growing evidence that metalinguistic awareness is a reliable indicator of developing second language competence. Furthermore, it has been shown that language aptitude is significantly related to metalinguistic awareness. The present study was designed to investigate the statistical relationship between second language grammaticality judgments and selected cognitive and linguistic variables. The variables studied were second language proficiency, second language classroom achievement, first language reading competence, language aptitude, nonverbal intelligence, field dependence-independence, and a written grammaticality judgment test tapping the ability to recognize, and correct, deviance. Subjects were college students in advanced English-as-a-second-language classes. Multivariate statistical techniques were used to determine the relative contribution of linguistic and cognitive variables to the individual variation demonstrated by the learners in their ability to detect deviance in English. The results showed that second language proficiency, second language achievement in the classroom, and language aptitude were significant predictors of the subjects' ability to make grammaticality judgments. First language reading competence was significantly related to subjects' ability to correct deviance. These observations are discussed in the light of: (1) the relationship among cognition, language, and metalinguistic awareness, and (2) the role of metalinguistic awareness in second language acquisition and second language learning.     

Judgments of grammaticality of sentences violating the principle of full interpretation: a further exploration

54 Japanese speakers judged isolated simple bitransitive sentences involving an unnecessary extra argument in addition to three legitimate arguments. Two variables were manipulated, with one variable concerning the role the extra argument assumed in a sentence, subjective, dative, or objective and the other concerning the relation it bore with the legitimate argument. The sentences with the extra arguments were judged to be an average grammaticality of about 3 on a 7-point scale. This score, although still lower than that obtained for sentences involving only the legitimate arguments, suggests that speakers' judgments are not fully consistent with the judgments expected if they might possess and demonstrate the knowledge of the principle of Full Interpretation.     

Grounding by Attention Simulation in Peripersonal Space: Pupils Dilate to Pinch Grip But Not Big Size Nominal Classifier

Grammatical categories represent implicit knowledge, and it is not known if such abstract linguistic knowledge can be continuously grounded in real‐life experiences, nor is it known what types of mental states can be simulated. A former study showed that attention bias in peripersonal space (PPS) affects reaction times in grammatical congruency judgments of nominal classifiers, suggesting that simulated semantics may include reenactment of attention. In this study, we contrasted a Chinese nominal classifier used with nouns denoting pinch grip objects with a classifier for nouns with big object referents in a pupil dilation experiment. Twenty Chinese native speakers read grammatical and ungrammatical classifier‐noun combinations and made grammaticality judgment while their pupillary responses were measured. It was found that their pupils dilated significantly more to the pinch grip classifier than to the big object classifier, indicating attention simulation in PPS. Pupil dilations were also significantly larger with congruent trials on the whole than in incongruent trials, but crucially, congruency and classifier semantics were independent of each other. No such effects were found in controls.     

Subject-Object Ambiguities in German Embedded Clauses: An Across-the-Board Comparison

This paper examines the processing of embedded clauses in German which are ambiguous between a subject-before-object and an object-before-subject order. In an experiment using a speeded grammaticality judgment task, four types of locally ambiguous clauses were compared: (i) sentences involving movement of a definite noun phrase (NP), (ii) sentences involving pronoun movement, (iii) relative clauses, and (iv) embedded questions. We found that readers were consistently garden-pathed in the object-before-subject condition, regardless of sentence type. Furthermore, there were considerable differences with respect to garden-path strength. The garden-path effect was strongest for sentences involving scrambling. In addition, sentences involving pronoun movement induced more processing difficulty than embedded questions and relative clauses. We argue that our findings can be best explained within a serial processing model that acknowledges both syntactic and nonsyntactic influences on reanalysis and that can account for graded effects of garden-path strength.     

Sentence processing deficits in two Cantonese aphasic patients

This paper reports the performances of two Cantonese aphasics on tasks examining their sentence processing deficits. The data on sentence comprehension show that thematically noncanonical sentences, full passives, and subject-gap sentences present greater difficulty to these patients than canonical sentences, truncated passives, and object-gap sentences, respectively. These patterns are consistent with previous observations on Chinese aphasics and are expected given the structural differences between Chinese and English. In a Cantonese grammaticality judgment test, a set of structures are identified that can elicit clear judgments from normal subjects and aphasics, contrary to the claim that grammaticality judgments in Chinese are probabilistic and fragile. Most interestingly, the patients' overall performance patterns reveal a double dissociation between sentence comprehension and judgment of sentence well-formedness, suggesting that the two tasks are supported by independent processing mechanisms.     

The role of similarity in artificial grammar learning

The authors examine the role of similarity in artificial grammar learning (AGL; A. S. Reber, 1989). A standard finite-state language was used to create stimuli that were arrangements of embedded geometric shapes (Experiment 1), connected lines (Experiment 2), and sequences of shapes (Experiment 3). Main effects for well-known predictors from the literature (grammaticality, associative global and anchor chunk strength, novel global and anchor chunk strength, length of items, and edit distance) were observed, thus replicating previous work. However, the authors extend previous research by using a widely known similarity-based exemplar model of categorization (the generalized context model; R. M. Nosofsky, 1989) to fit grammaticality judgments, by nested regression analyses. The results suggest that any explanation of AGL that is based on the existing theories is incomplete without a similarity process as well. Also, the results provide a foundation for further interpreting AGL in the wider context of categorization research.     

Code switching by bilinguals: Evidence against a third grammar

Bilingual code switching within sentences (as in “The towel roja was dirty”) is often observed in bilingual communities. The present study addressed two issues. First, what is the nature of the grammatical rules that underlie code switching? Second, how do bilingual speakers acquire such rules? We addressed the first issue by obtaining judgments of the grammaticality of four types of sentences containing code-switched words. Judgments of acceptability seemed to be based on two rules: (1) Code switching can occur only when the code-switched words are positioned in accord with the rules for which they are approriate lexical items; (2) code switching within word boundaries is considered ungrammatical. We addressed the second issue by exploring the effects of age and code switching experience on the grammatical judgments of bilingual children and adults. Extensive code-switching experience did not seem to be necessary for bilingual speakers to know the grammatical constraints of code switching. This suggests that the constraints of code switching are based on the integration of the grammars of the two code-switched languages rather than on the creation of a third grammar. There were developmental changes in the judgments made to the sentences. All aged subjects found sentences that violated the word-order rule (1 above) unacceptable. However, the youngest children (8- to 10-year-olds) found mixing within a word acceptable. This developmental change could be due to a change in the grammar of code switching, in the ability to make metalinguistic judgments, or in the child's general knowledge about the nature of languages.     

Absolute identification of notes and intervals by musicians

Speech sounds are judged reliably and absolutely, while the judgment of nonspeech stimuli, such as tones, is thought to be unreliable and dependent on contextual cues. Here we demonstrated that the judgment of tonal stimuli may also be reliable and absolute, provided that the subjects are trained musicians. In Experiment 1, musicians with relative pitch identified 21 tonal intervals ranging from unison to major third, and the resulting identification functions were similar to those that have been previously obtained for speech. In Experiment 3, the judgment of intervals by musicians was shown to be free of context effects, since the best subjects gave virtually identical judgments to the same intervals in two stimulus contexts. Similar results were obtained in Experiments 2 and 4 for the judgment of single tones by possessors of absolute pitch. Performance with both notes and intervals by nonmusicians, however, was unreliable and greatly influenced by context. These findings suggest that musicians acquire categories for pitch that are functionally similar to phonemic categories for speech     

Faulty Japanese sentences are judged more grammatical when punctuation is used: negative implications for Chomsky's principle of Full Interpretation

88 adult Japanese speakers judged the grammaticality of isolated simple bitransitive sentences involving an uninterpretable extra argument in addition to three legitimate arguments. The sentences thus violated Chomsky's principle of Full Interpretation which prohibits the structure building of a sentence including uninterpretable elements. The primary variable of interest was the presence or absence of punctuation, i.e., commas, which enclosed the extra argument. Findings showed that sentences with punctuation were judged more grammatical than the ones without punctuation, with an average score of judged grammaticality exceeding 3 on a 7-point scale (1 =least grammatical; 7=most grammatical). This score would not be expected if the speakers possess and judge the sentences in conformity with the principle of Full Interpretation.     

Cross‐Linguistic Differences in Processing Double‐Embedded Relative Clauses: Working‐Memory Constraints or Language Statistics?

An English double‐embedded relative clause from which the middle verb is omitted can often be processed more easily than its grammatical counterpart, a phenomenon known as the grammaticality illusion. This effect has been found to be reversed in German, suggesting that the illusion is language specific rather than a consequence of universal working memory constraints. We present results from three self‐paced reading experiments which show that Dutch native speakers also do not show the grammaticality illusion in Dutch, whereas both German and Dutch native speakers do show the illusion when reading English sentences. These findings provide evidence against working memory constraints as an explanation for the observed effect in English. We propose an alternative account based on the statistical patterns of the languages involved. In support of this alternative, a single recurrent neural network model that is trained on both Dutch and English sentences is shown to predict the cross‐linguistic difference in the grammaticality effect.     

The effect of constant outcome value on judgments and decision making given linguistic probabilities

Two experiments were performed to determine whether judgments of the relative chances of two independent events occurring are biased by constant outcome values contingent on the events when the uncertainties are specified by linguistic expressions (e.g. doubtful). In Experiment 1, subjects directly judged the relative chances of the two events, of which one was represented by a spinner and the other by a linguistic probability expression. In Experiment 2, only linguistic probability expressions were used to describe the two events and a betting procedure was used. A bias was evident in both studies, such that the relative judgments tended to favour the event with the positive rather than the negative contingent outcome. The bias was smaller for the low- than for the high-probability phrases. Individual differences were great, with the bias appearing strongly in only about one-third of the population. Theoretical implications of the present and related results are discussed.     

Effect of Repeated Evaluation and Repeated Exposure on Acceptability Ratings of Sentences

This study investigated the effect of repeated evaluation and repeated exposure on grammatical acceptability ratings for both acceptable and unacceptable sentence types. In Experiment 1, subjects in the Experimental group rated multiple examples of two ungrammatical sentence types (ungrammatical binding and double object with dative-only verb), and two difficult to process sentence types [center-embedded (2) and garden path ambiguous relative], along with matched grammatical/non-difficult sentences, before rating a final set of experimental sentences. Subjects in the control group rated unrelated sentences during the exposure period before rating the experimental sentences. Subjects in the Experimental group rated both grammatical and ungrammatical sentences as more acceptable after repeated evaluation than subjects in the Control group. In Experiment 2, subjects answered a comprehension question after reading each sentence during the exposure period. Subjects in the experimental group rated garden path and center-embedded (1) sentences as higher in acceptability after comprehension exposure than subjects in the control group. The results are consistent with increased fluency of comprehension being misattributed as a change in acceptability.
