The relativity of linguistic intuition: The effect of repetition on grammaticality judgments

Three experiments were performed to show the relativity of linguistic intuition in grammaticality judgments. In Experiment 1, 12 students judged the relative grammaticality of isolated 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 show that the repetition treatment makes a judgment criterion more stringent for both grammatical and ungrammatical sentences. In Experiment 2, a release-from-the-proactive-inhibition paradigm was used. Twelve students first judged the grammaticality of the isolated sentences, then received the repetition treatment, and finally, made a second judgment for the sentences embedded in context. No change in judgment criterion was found for the second judgment. Judgments of the ungrammatical sentences, when embedded in context, were found to be more lenient. In Experiment 3, 12 students judged sentences embedded in context. No change in judgment criterion was found. These findings are interpreted as suggesting that linguistic intuitions as revealed in grammaticality judgments are not absolute but relative in that they are easily influenced by repetition and other variables, such as embedded context.     

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.     

How does repetition affect memory? Evidence from judgments of recency

Four experiments were done to investigate the effects of repetition on judgment of recency (JOR). Experiment 1 showed that repetition can make an item seem either more recent or less recent than a nonrepeated item, depending on presentation spacing. Experiments 2-4 showed that subjects are able to judge the recency of a repeated item’s first presentation or of its second presentation with a high degree of independence, especially if they report that the item occurred twice. The data are more consistent with an independent-trace explanation of JOR and repetition than with a cumulative-strength account, but neither hypothesis explains how repetition can make an item seem less recent. It is proposed that the findings as a whole can be better explained by a hypothesis based on recursive reminding.     

Repetition priming and face processing: Priming occurs within the system that responds to the identity of a face

A familiar stimulus that has recently been recognized will be recognized a second time more quickly and more accurately than if it had not been primed by the earlier encounter. This is the phenomenon of “repetition priming”. Four experiments on repetition priming of face recognition suggest that repetition priming is a consequence of changes within the system that responds to the familiarity of a stimulus. In Experiment 1, classifying familiar faces by occupation facilitated subsequent responses to the same faces in a familiarity decision task (Is this face familiar or unfamiliar?) but not in an expression decision task (Is this face smiling or unsmiling?) or a sex decision task (Is this face male or female?). In Experiment 2, familiar faces showed repetition priming in a familiarity decision task, regardless of whether a familiarity judgment or an expression judgment had been required when the faces were first encountered. Expression decisions to familiar faces again failed to show repetition priming. In Experiment 3, familiar faces showed repetition priming in a familiarity decision task, regardless of whether a familiarity judgment or a sex judgment had been asked for when the faces were first encountered. Sex decisions to familiar faces again failed to show repetition priming. In Experiment 4, familiarity decisions continued to show repetition priming when a brief presentation time with encouragement to respond while the face was displayed reduced response latencies to speeds comparable to those for sex and expression judgments in Experiments 1 to 3. The results are problematic for theories that propose that repetition priming is mediated by episodic records of previous acts of stimulus encoding.     

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.     

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.     

Reactions to objective self-awareness

In order to determine reactions to objective self-awareness, 96 female undergraduates received either positive or negative feedback on a “creativity” task prior to being given an opportunity to write a response to a visual cue. Half of the subjects were made objectively self-aware, via a mirror, during the visual cue task; half were not. In addition, half of the subjects were led to believe that the visual cue task was highly related to creativity, while half learned that the task was low in relevance. A “longer the response, the better” standard of correctness was established for all subjects. As predicted, the results indicated that when made objectively self-aware, subjects who received negative feedback wrote more in response to the visual cue than did those who received positive feedback, a difference which was not obtained for the subjectively self-aware subjects. The task relevance manipulation also produced a significant main effect. A similar pattern of results was obtained on a measure of the time spent on the task. The implications of the results for objective self-awareness theory are considered.     

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.

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.     

Memorability judgments for high- and low-frequency words

Five experiments were conducted in order to examine subjects’ judgments of the memorability of high- (HF) and low-frequency (LF) words in the context of a recognition memory task. In Experiment 1, the subjects were provided study/test experience with a list of HF and LF words prior to making memorability judgments for a new list of HF and LF items. The findings were consistent with previous evidence (Greene & Thapar, 1994; Wixted, 1992) suggesting that subjects are not explicitly aware of the greater recognition memorability of LF words. Experiments 2–5 embedded the memorability judgment task within the recognition test itself. In these experiments, the subjects consistently gave higher memorability ratings to LF items. The contrast between the pattern of results found when the subjects made their judgments at the time of list presentation (Experiment 1) and that when they made their judgments during the recognition test (Experiments 2–5) is consistent with recent evidence that even seemingly highly related metamnemonic judgments (e.g., ease of learning judgments vs. judgments of learning for the same items) may be based on very different factors if they occur at different points in the study/test cycle. The present findings are also consistent with the possibility that very rapid retrieval of memorability information for HF and LF words may affect recognition decisions and may contribute to the recognition memory word frequency effect.     

Repetition blindness: The effects of stimulus modality and spatial displacement

Repetition blindness (Kanwisher, 1986, 1987) is the failure to detect repetitions of words in lists presented in rapid serial visual presentation (RSVP). Two questions were investigated in the present study. First, if repetition blindness is not found with auditory presentation, it would support a specifically visual account of the effect. Second, if displacement of the two instances in visual space eliminates repetition blindness, it would suggest that repetition blindness is restricted to instances in which identical stimuli are distinguished soley by temporal differences. In Experiment 1, the subjects omitted second occurrences of repeated words in verbatim recall of rapid sentences presented visually (in RSVP), but not auditorily (using compressed speech), indicating that repetition blindness is a modality-specific phenomenon. In Experiments 2 and 3, repetition blindness was observed even when two occurrences of a written word were presented in different locations, showing that distinct locations do not guarantee token individuation. The results are discussed within a model that distinguishes between processes of type recognition and token individuation.     

Recency judgments as a function of word frequency: A framing effect and frequency misattributions

The effects of word frequency on judgments of recency of item presentation were examined in two experiments. Subjects in Experiment 1 were presented two mixed lists of high- and low-frequency words followed by a list assignment task for recognized items. It was found that subjects were biased toward assigning low-frequency words to the more recently presented list. Subjects in Experiment 2 were presented a single mixed list of high- and low-frequency words followed by either a relative recency of presentation judgment task or a relative primacy of presentation judgment task. Each word pair on the tests contained one high-frequency word and one low-frequency word. It was found that, for the recency judgment task, subjects were biased to select the low-frequency item as having been presented more recently. However, on the parallel primacy judgment task, there were no effects of word frequency; moreover, overall accuracy levels were higher with primacy than with recency instructions. We interpret the effects of word frequency on recency judgments in Experiments 1 and 2 in terms of a misattribution of frequency-related differences in recollection-based recognition. The finding that recency and primacy instructions produced different patterns of results provides further evidence (Flexser & Bower, 1974) for an effect on performance of the way in which the temporal judgment task was framed.     

Evidence for a late-occurring effect of phoneme repetition during silent reading

Two reading experiments were conducted to investigate the effect of phoneme repetition during silent reading (also referred to as the visual tongue-twister effect, see McCutchen & Perfetti, 1982; Perfetti & McCutchen, 1982) in conjunction with end-of-clause and end-of-sentence wrap-up effects (Just & Carpenter, 1982; Rayner, Sereno, Morris, Schmauder, & Clifton, 1989). In both experiments, reading time was measured on sentences containing either six or zero words sharing the same initial phoneme. Sentences were presented in a phrase-by-phrase moving window, with each phrase either containing one word that involved a repeated phoneme or a matched word not involving a repeated phoneme. The sixth presentation region either contained or did not contain a comma (Experiment 1) or a period (Experiment 2). The results showed that the effect of phoneme repetition occurred relatively late during sentence processing, only after integration processing related to end-of-clause and end-of-sentence wrap-up occurred.     

Processing resource capacity and the comprehension of garden path sentences

Three experiments explored the relationship between verbal working memory capacity and the comprehension of garden path sentences. In Experiment 1, subjects with high, medium, and low working memory spans made acceptability judgments about garden path and control sentences under whole sentence and rapid serial visual presentation (RSVP) conditions. There were no significant differences between subjects with different working memory spans in the comprehension of garden path sentences in either condition. In Experiments 2A and 2B, subjects with high and low working memory spans were tested on the same materials at three RSVP rates. There were no significant differences between subjects with different working memory spans in the magnitude of the effect of garden path sentences at any presentation rate. The results suggest that working memory capacity, as measured by the Daneman and Carpenter (1980) reading span task, is not a major determinant of individual differences in the processing of garden path sentences.     

REPETITION DEAFNESS:

Abstract— This research demonstrates a new cognitive phenomenon known as repetition deafness, a difficulty in immediate recall of repeated words in computer-compressed speech Sixty-four subjects heard sentences and lists at four speeded rates 70, 55, 35, and 28 msl phoneme Each target word in the materials followed a pretarget word that was either identical (repeated-target condition) or different (unrepeated-target condition), and targets were harder to recall when repeated than unrepeated Repetition deafness was rate-limited, occurring only with rapid rates of presentation (55 mslphoneme or less), and decreased in magnitude as structure increased from lists to sentences Implications for current theories of repetition deficits are discussed     

Text cohesion and metacomprehension: Immediate and delayed judgments

In three experiments, we examined comprehension judgments made after a piece of text had been read. We propose that such metacognitive judgments are based on the content of working memory at the exact moment of assessment. Generally speaking, this working metacognition hypothesis is in agreement with Koriat's cue utilization approach, which implies that different elements of information will be available (and used) depending on the moment at which a judgment is made. More specifically, our hypothesis focuses on the management of working memory during reading as a cause for cue (un)availability. In support of these views, the results of Experiment 1 showed that a cohesion manipulation affecting the comprehension of specific paragraphs influences judgments only on these paragraphs, and not on judgments on the whole text. In Experiment 2, we showed that an interfering task that takes place just before this paragraph judgment is made wipes out this cohesion effect. Experiment 3 showed, on the other hand, that the whole-text judgment may, nevertheless, be affected by text cohesion, provided that the readers keep an access to the text when the judgment is made. These results support the idea that working memory management makes different cues available for metacognitive ratings at different delays.     

Integration of Intention and Outcome Information by Students and Circuit Court Judges: Design Economy and Individual Differences1

In two experiments the subjects, who included State Circuit Court Judges, assigned a quantitative judgment of blame to hypothetical offenders as a function of level of intention and seriousness of outcome. In accordance with the findings of numerous other investigators using the Intent x Damage paradigm, averaged subjects appeared to follow an adding rule for the integration of intention and outcome damage information. Furthermore, and in keeping with a key methodological purpose of the research, equivalent averaged results were observed whether student subjects made just one judgment of a single Level of Intention x Level of Outcome Damage treatment combination (independent groups design) or multiple judgments of all possible such factorial treatment combinations (repeated measures design). However, statistical analysis of individual students' and individual judges' repeated measures showed that about half of them adopted an adding rule whereas the judgments of others conformed to an intention-only rule. Some implications of the findings are: (a) in critical respects students' results are quite generalizable since there were no striking student versus judge differences; (b) averaged outcomes conceal important interpretable individual differences in information processing that are highly commensurate for students and judges; and (c) there is thus a defensible and pragmatically desirable economy in the adoption of repeated measures designs for the study of individual persons in such less accessible categories as the Judiciary.
